Description

Die Erfindung betrifft eine Hochwasserschutzvorrichtung für Deckensektionaltore, wie sie als Garagen- oder Hallentore Verwendung finden. Deckensektionaltore sind aus sich über die Torbreite sowie über eine gewisse Höhendistanz erstreckenden Segmentplatten zusammengesetzt, die mit Scharniergelenken miteinander verbunden sind und ein Verschieben des Tors zum Öffnen und Schließen zwischen einer vertikalen Schließstellung und einer etwa horizontal entlang der Decke umgelenkten Öffnungsstellung ermöglichen.The invention relates to a flood protection device for overhead sectional doors, as they are used as garage or hall doors. Ceiling sectional doors are composed of over the gate width and over a certain height distance extending segment plates, which are connected by hinge joints and allow movement of the door to open and close between a vertical closed position and an approximately horizontally folded along the ceiling opening position.

Aufgrund der zunehmenden Häufigkeit und Schwere starker Regenfälle mit der Gefahr von Überschwemmungen ist es wünschenswert, Garagen- oder Hallentore mit einem Hochwasserschutz auszustatten, der das Eindringen von Hochwasser in die Garage oder Halle verhindert.Due to the increasing frequency and severity of heavy rains with the risk of flooding, it is desirable to provide garage or hall gates with flood protection that prevents the ingress of flood into the garage or hall.

Hochwasserschutzvorrichtungen zum Verschließen und Abdichten von Gebäudeöffnungen sind bereits in verschiedenen Ausgestaltungen bekannt.Flood protection devices for sealing and sealing of building openings are already known in various embodiments.

Aus der DE 295 18 074 U1 ist beispielsweise ein Notverschluß zum dichten Verschließen einer von starren Wänden begrenzten Öffnung eines Gebäudes bekannt, der aus einer an die Kontur der Öffnung angepaßten und die Öffnung im wesentlichen abdeckenden oder ausfüllenden Verschlußelement sowie einem zwischen diesem und den angrenzenden starren Wänden der Öffnung anliegenden Dichtelement besteht, das schlauchartig ausgebildet und durch Einleiten eines Druckmittels expandierbar ist, also beispielsweise mit Druckluft aufgeblasen werden kann.From the DE 295 18 074 U1 For example, an emergency seal for sealing a limited opening of a rigid wall of a building is known, which consists of an adapted to the contour of the opening and the opening substantially covering or filling closure element and a voltage applied between the latter and the adjacent rigid walls of the opening sealing element, the tube-like design and is expandable by introducing a pressure medium, so it can be inflated, for example, with compressed air.

Eine derartige Vorrichtung in Gestalt eines Garagenkipptors zum Verschließen einer Toröffnung unter Verwendung einer aufblasbaren Dichtung ist aus der DE 20 2011 004 273 U1 bekannt, wo der mit Druckgas befüllbare elastische Schlauch zur Herstellung einer wasserdichten Abdichtung bei geschlossenem Torflügel in einer umlaufenden Nut des Torflügels angeordnet ist.Such a device in the form of a garage door for closing a door opening using an inflatable seal is known from DE 20 2011 004 273 U1 known where the filled with compressed gas elastic hose for producing a watertight seal with the door closed in a circumferential groove of the door leaf is arranged.

Die bekannten Lösungen eignen sich aber nicht für Deckensektionaltore, die aus miteinander verbundenen, sich jeweils über die Torbreite erstreckenden und mit Scharnieren verbundenen Segmentplatten bestehen.However, the known solutions are not suitable for ceiling sectional doors, which consist of interconnected, each extending over the door width and connected with hinged segment panels.

Aufgabe der Erfindung ist es daher, eine Hochwasserschutzvorrichtung zu schaffen, die insbesondere auf die Anwendung bei Deckensektionaltoren abgestimmt ist.The object of the invention is therefore to provide a flood protection device, which is particularly adapted to the application in ceiling section doors.

Diese Aufgabe wird gemäß der Erfindung durch die im Anspruch 1 angegebene Anordnung gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved according to the invention by the arrangement specified in claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Ein wirksamer Hochwasserschutz erfordert bei einem Deckensektionaltor nicht nur die Abdichtung von Fugen, die zwischen dem geschlossenen Tor und dem Torrahmen bzw. dem Boden sowie auch zwischen benachbarten Segmentplatten bestehen, sondern erfordert auch Maßnahmen gegen eine Verformung des Tors unter dem Wasserdruck.Effective flood protection in a deck sectional door not only requires the sealing of joints existing between the closed gate and the goal frame or the floor, but also between adjacent segment panels, but also requires measures against deformation of the door under the water pressure.

Deckensektionaltore bestehen in der Regel aus Segmentplatten in Gestalt von Stahlpaneelen, die beispielsweise innen und außen eine Wand aus 0,5 mm dickem Stahlblech haben, wobei der Zwischenraum zwischen diesen Wänden mit PU-Schaum ausgeschäumt ist. Solche Paneele werden bei der Fertigung in der Breite entsprechend dem geforderten Tormaß geschnitten und mit U-Endkappen versehen. Handelsübliche Höhen der einzelnen Segmentplatten sind gegenwärtig 50 cm, 60 cm und 70 cm. Soll also ein wirksamer Schutz beispielsweise gegen Hochwasser mit einem Pegelstand bis zu 1 m gewünscht werden, ist es nötig, die zwei untersten Segmentplatten jeweils so zu versteifen, dass sie gegen ein Eindrücken bzw. Verformen durch von außen drückendes Wasser beständig sind, wobei die Qualität der Versteifung natürlich von der Breite des Tors abhängig ist.Ceiling sectional doors are usually made of segment panels in the form of steel panels, for example, inside and outside have a wall of 0.5 mm thick steel sheet, the gap between these walls is foamed with PU foam. Such panels are cut in the production in width according to the required Tormaß and provided with U-end caps. Commercial heights of the individual segment plates are currently 50 cm, 60 cm and 70 cm. So if an effective protection, for example against flood with a water level up to 1 m are desired, it is necessary to stiffen the two bottom segment plates in each case so that they are resistant to indentation or deformation by pressing from the outside water, the quality the stiffening of course depends on the width of the gate.

Die Versteifung der Segmentplatten kann durch einen an der Innenseite der betreffenden Segmentplatte angebauten Versteifungsrahmen erfolgen, der vorteilhafterweise aus Vierkantrohrprofilen aufgebaut ist.The stiffening of the segment plates can be done by a mounted on the inside of the relevant segment plate stiffening frame, which is advantageously constructed of square tube profiles.

Zur Abdichtung des Tors in geschlossenem Zustand dienen mit Druckmittel füllbare und expandierbare Dichtungselemente, die zwischen die Toröffnung beiderseits begrenzenden wandfesten Bauteilen und den Segmentplatten über die gewünschte Höhe angeordnet sind. Eine solche druckmittelbeaufschlagbare Dichtung kann auch vertikal an den beiden Seiten und horizontal entlang des Unterkantenbereichs der untersten Segmentplatte verlaufen und ist dann an der Segmentplatte oder vorzugsweise an dem damit verbundenen Versteifungsrahmen angeordnet.To seal the door in the closed state serve with pressure medium fillable and expandable sealing elements, which are arranged between the door opening on both sides limiting wall-fixed components and the segment plates over the desired height. Such a pressurizable seal may also extend vertically on both sides and horizontally along the lower edge region of the lowermost segment plate and is then disposed on the segment plate or, preferably, on the associated stiffening frame.

Als zusätzliche Maßnahme sind mechanische Verriegelungen vorgesehen, die an den wandfesten, die Toröffnung beiderseits begrenzenden Bauteilen angeordnete ausfahrbare Riegelbolzen umfassen, die bei Beaufschlagung der Dichtungen mit Druckmittel gleichzeitig durch Beaufschlagung mit Druckmittel ausgefahren und in Öffnungen der jeweiligen Segmentplatte eingeführt werden können. Dadurch werden die Segmentplatten in ihrer Position fixiert und stabilisiert, so dass sie unter der Einwirkung von drückendem Hochwasser nicht auslenkbar sind. Solche ausfahrbaren Riegelbolzen können auch im Boden über die Torbreite verteilt vorgesehen sein und in Öffnungen im Unterkantenbereich der untersten Segmentplatte einführbar sein. Alternativ können die Riegelbolzen am Versteifungsrahmen angeordnet und in Öffnungen der wandseitigen Bauteile und des Bodens ausfahrbar sein.As an additional measure mechanical interlocks are provided which on the wall-fixed, the door opening on both sides delimiting components arranged extendable locking bolts, which can be extended upon exposure to the seals with pressure medium simultaneously by applying pressure medium and inserted into openings of the respective segment plate. As a result, the segment plates are fixed in position and stabilized so that they are not deflected under the influence of oppressive flood. Such extendable locking bolts can also be provided distributed in the floor over the gate width and be insertable into openings in the lower edge region of the lowermost segment plate. Alternatively, the locking bolts can be arranged on the stiffening frame and extendable in openings of the wall-side components and the floor.

Zur Abdichtung der Fugen zwischen dem Unterkantenbereich der untersten Segmentplatte und zwischen aufeinanderfolgenden Segmentplatten können ebenfalls mit Druckmittel füllbare und expandierbare Dichtungen vorgesehen sein. Die Fixierung der Segmentplatten durch die ausfahrbaren Riegelbolzen verhindert dabei, dass durch das Expandieren der Dichtungen die Segmentplatten auseinander gedrückt oder vom Boden abgehoben werden können, so dass die Dichtungswirkung nicht beeinträchtigt wird.For sealing the joints between the lower edge region of the lowermost segmental plate and between successive segmental plates can also be provided with pressure medium fillable and expandable seals. The fixation of the segment plates by the extendable locking bolt thereby prevents the segment plates can be pushed apart or lifted off the ground by the expansion of the seals, so that the sealing effect is not affected.

Schließlich sieht die Erfindung vor, dass das Abdichten und Sichern des Tors bei Auftreten von Hochwasser automatisch erfolgt.Finally, the invention provides that the sealing and securing of the gate occurs automatically when flood occurs.

Dazu kann ein Behälter vorgesehen sein, der so angeordnet ist, dass er sich zwar nicht bei normalem Regen, aber bei beginnender Überschwemmung mit Wasser füllt, und in dem ein schwimmerbetätigter Auslöser vorhanden ist, der bei Betätigung durch den Schwimmer das Füllen und Expandieren der Dichtungen und das Ausfahren der Riegelbolzen bewirkt. Weiter ist ein Druckmittelspeicher vorhanden, in dem unter permanent aufrechterhaltenem Druck Druckmittel gespeichert ist, das über ein Ventil, das durch den schwimmerbetätigten Auslöser geöffnet werden kann, die Dichtungen füllt und expandiert und die Riegelbolzen ausfährt. Durch den Druckspeicher ist sichergestellt, dass auch bei Stromausfall der Druck vorhanden und nicht von der Funktionsfähigkeit eines elektrisch betriebenen Kompressors abhängig ist. Dementsprechend kann auch der schwimmerbetätigte Auslöser ein unmittelbar oder über eine Auslösestange betätigbares Schaltorgan in einem Druckmittelkreis sein und somit ebenfalls von einer elektrischen Stromversorgung unabhängig sein.For this purpose, a container may be provided which is arranged so that it does not fill with normal rain, but at the onset of flooding with water, and in which a float-actuated trigger is present, the filling and expanding the seals when actuated by the float and the extension of the locking bolt causes. Next, a pressure fluid reservoir is present in which pressure medium is stored under permanently maintained pressure, which fills and expands the seals and a valve that can be opened by the float-actuated trigger seals and extends the locking bolt. The pressure accumulator ensures that the pressure is available even in the event of a power failure and does not depend on the functionality of an electrically operated compressor. Accordingly, the float-actuated trigger can be an actuatable directly or via a trip bar switching element in a pressure medium circuit and thus also be independent of an electrical power supply.

Da das Abdichten und Sichern nur bei geschlossenem Tor geschehen kann, kann durch ein vom Tor betätigtes Organ, beispielsweise in Gestalt eines Endschalters, der Schließzustand des Tors verifiziert und nur dann das Auslösen des Expandierens der Dichtungen und des Ausfahrens der Riegelbolzen ermöglicht werden.Since the sealing and securing can only be done when the door is closed, can be verified by a gate operated organ, for example in the form of a limit switch, the closing state of the door and only then trigger the expansion of the seals and the extension of the locking bolts.

Weiter kann bei motorischem Torantrieb das automatische Schließen des geöffneten Tors durch den schwimmerbetätigten Auslöser ausgelöst werden, bevor dann nach Erreichen des Schließzustands das Expandieren der Dichtungen und das Ausfahren der Riegelbolzen ausgelöst wird.Next can be triggered by the float-actuated trigger with automatic door drive, the automatic closing of the open door, before then after reaching the closed state, the expansion of the seals and the extension of the locking bolt is triggered.

Als Druckmittel wird vorzugsweise Pressluft verwendet, und der Druckmittelbehälter kann ein Pressluftbehälter mit beispielsweise 10 Litern Fassungsvermögen sein, der auf einem vorgegebenen Druck gehalten wird, der bei Unterschreiten eines vorgegebenen Grenzwerts jeweils wieder durch einen sich automatisch einschaltenden elektrischen Kompressor aufgefüllt wird.As pressure medium preferably compressed air is used, and the pressure medium container may be a compressed air tank with, for example, 10 liters capacity, which is maintained at a predetermined pressure, which is filled when falling below a predetermined limit each again by an automatically turning on electric compressor.

Um eine noch größere stromversorgungsunabhängige Sicherheit zu erreichen, kann auch bei handbetätigtem oder elektromotorisch betriebenem Tor eine druckmittelbetätigte automatische Schließvorrichtung vorgesehen sein und der Druckmittelvorrat ausreichend groß gemacht werden, um bei geöffnetem Tor dieses bei Auslösung mittels Druckmittel, also beispielsweise Druckluft, erst zu schließen und dann die Dichtungen aufzublasen und die Riegel auszufahren. Da bei schweren Unwettern stets mit Stromausfall, beispielsweise durch Blitzeinschlag irgendwo im elektrischen Stromnetz, gerechnet werden muss, ist eine stromversorgungsunabhängige Funktion der Hochwassersicherung sehr wichtig. Ebenfalls wichtig ist die automatische Betätigung, um auch in Abwesenheit des Betreibers die Absicherung gegen Hochwasser sicher zu stellen.To achieve an even greater power supply independent security, a pressure-medium-operated automatic closing device can be provided and the pressure medium supply can be made sufficiently large even when manually operated or electric motor operated gate to open this door when triggered by pressure medium, ie For example, compressed air, first to close and then inflate the seals and extend the bolt. Since in heavy storms always with power failure, for example by lightning somewhere in the electrical network, must be expected, a power supply independent function of the flood protection is very important. Also important is the automatic operation, in order to ensure the protection against flood even in the absence of the operator.

Die Abdichtung der untersten Segmentplatte gegen den Boden kann auch durch eine rein mechanische Dichtung erfolgen, die beim Schließen des Tors zwischen dem Unterkantenbereich der untersten Segmentplatte und dem Boden gestaucht oder gequetscht wird, um einen für eine sichere Abdichtung erforderlichen hohen Anpressdruck zu erzeugen. Bei Auslösung der Hochwasserabdichtung kann auch vorgesehen sein, dass mittels Druckmittelzylindern, die gleichzeitig mit den Dichtungen druckmittelbeaufschlagt werden, das geschlossene Tor nach unten vorgespannt wird und erst dann die Sicherungsbolzen ausgefahren werden. Auch die Abdichtung zwischen benachbarten Segmentplatten kann dadurch erfolgen, dass zwischen diesen statt einer druckmittelbeaufschlagbaren Dichtung eine normale mechanische Dichtung vorgesehen wird, die, wenn die benachbarten Segmentplatten sich fluchtend in Schräglage befinden, so stark komprimiert ist, dass eine sichere Abdichtung sichergestellt ist.The sealing of the lowermost segment plate against the floor can also be effected by a purely mechanical seal, which is compressed or crushed when closing the door between the lower edge region of the lowermost segment plate and the ground to produce a high contact pressure required for a secure seal. When the flood seal is triggered, it can also be provided that the closed gate is biased downwards by means of pressure medium cylinders, which are subjected to pressure medium simultaneously with the seals, and only then the securing bolts are extended. The sealing between adjacent segment plates can also take place in that a normal mechanical seal is provided between them instead of a pressure-medium-loading seal, which, when the adjacent segment plates are aligned in an inclined position, is so strongly compressed that a secure seal is ensured.

Das ganze druckmittelbetätigte System kann an den wandfesten Bauteilen angeordnet sein und es bedarf keiner Druckmittelzufuhr zu Elementen des Tors, oder, wie oben erwähnt, können die druckmittelbeaufschlagbare Dichtung und die druckmittelbetätigten Riegelbolzen am Tor angeordnet sein, wobei dann flexible Druckmittelleitungen zu dem beweglichen Sektionaltor führen.The whole fluid-actuated system can be arranged on the wall-fixed components and it requires no pressure fluid supply to elements of the door, or, as mentioned above, the pressure-medium-loadable seal and the fluid-actuated locking bolt can be arranged at the gate, then lead flexible pressure medium lines to the movable sectional door.

Wird ein Hochwasserschutz gegen ein maximal erwartetes Hochwasser von beispielsweise ein Meter verlangt, ist es auch möglich, die beiden untersten Segmentplatten, die zusammen, je nach Höhe der einzelnen Segmentplatte, eine Gesamthöhe von 1,0 Meter bis 1,4 Meter ergeben, durch eine einstückige höhere Segmentplatte zu ersetzen oder die beiden untersten Segmentplatten nicht einzeln zu versteifen, sondern mit einem gemeinsamen Versteifungsrahmen zu einer einzigen Platte zu verbinden. Dadurch wird die Steifigkeit erhöht, und es kann dann auch eine entsprechende permanente Abdichtung der Fuge zwischen den beiden benachbarten Segmentplatten hergestellt werden.If a flood protection against a maximum expected flood of, for example, one meter is required, it is also possible, the two bottom segment plates, which together, depending on the height of each segment plate, a total height of 1.0 meters to 1.4 meters, by a to replace one piece higher segment plate or to stiffen the two bottom segment plates not individually, but to connect with a common stiffening frame to a single plate. This will increase the stiffness increases, and it can then be made a corresponding permanent sealing of the joint between the two adjacent segment plates.

Die beiden untersten Segmentplatten 2a und 2b sind durch einen an der Innenseite aufgesetzten Versteifungsrahmen 3 aus Vierkantrohrmaterial (wie in Figur 2 sichtbar) versehen, durch welchen die beiden untersten Segmentplatten 2a und 2b zu einer gemeinsamen Platte mit enormer Steifigkeit verbunden sind.The two lowermost segment plates 2a and 2b are secured by a stiffening frame 3 made of square tubing (as shown in FIG FIG. 2 Visible) provided by which the two lowermost segment plates 2a and 2b are connected to a common plate with enormous rigidity.

In Figur 2 ist das Sektionaltor 2 und die Wand 1 im Horizontalschnitt gezeigt, ebenso der an den beiden untersten Segmentplatten 2a und 2b innenseitig angebrachte Vierkantrohr-Versteifungsrahmen 3.In FIG. 2 is the sectional door 2 and the wall 1 shown in horizontal section, as well as the at the two lowermost segment plates 2a and 2b inside mounted square tube stiffening frame. 3

Weiter ist innenseitig an der Wand (wobei es sich auch um einen Stützpfosten handeln kann) auf jeder Seite der Toröffnung ein sich vertikal über die Höhe des gewünschten Hochwasserschutzes erstreckendes Profilteil 4 gegen die Wand 1 abgedichtet an dieser angebaut. Zwischen diesem Profilteil 4 und dem aus den beiden untersten Segmentplatten 2a und 2b bestehenden unteren Sektionaltorabschnitt ist eine aufblasbare Dichtung 5 vorgesehen. Beim Ausführungsbeispiel ist seitlich am Versteifungsrahmen 3 ein U-Profil 6 angebaut, das die aufblasbare Dichtung 5 aufnimmt, die sich dann an einer Gegenfläche 7 des Profilteils 4 abstützt.Next is on the inside of the wall (which may also be a support post) on each side of the door opening a vertically over the height of the desired flood protection extending profile part 4 sealed against the wall 1 grown on this. Between this profile part 4 and consisting of the two lowermost segment plates 2a and 2b lower Sektionaltorabschnitt an inflatable seal 5 is provided. In the embodiment, a U-profile 6 is attached to the side of the stiffening frame 3, which receives the inflatable seal 5, which is then supported on a mating surface 7 of the profile part 4.

Wie aus Figur 1 ersichtlich ist, verläuft die aufblasbare Dichtung 5 nicht nur entlang der beiden Seiten des Versteifungsrahmens 3, sondern durchgehend auch entlang der Unterkante des Versteifungsrahmens 3 in einem entsprechenden U-Profil, so dass eine Abdichtung seitlich und am Boden erfolgt.How out FIG. 1 it can be seen, the inflatable seal 5 extends not only along the two sides of the stiffening frame 3, but also continuously along the lower edge of the stiffening frame 3 in a corresponding U-profile, so that a seal takes place laterally and at the bottom.

Weiter sind, wie aus beiden Figuren 1 und 2 hervorgeht, sowohl seitlich als auch unten am Versteifungsrahmen 3 jeweils mehrere Riegelbolzen 8 vorgesehen, die druckmittelbetätigt ausfahrbar sind, um in Verriegelungsöffnungen im Boden und in den beiderseitigen Profilteilen 4 einzugreifen.Next are, like both FIGS. 1 and 2 It can be seen, both laterally and at the bottom of the stiffening frame 3 each provided a plurality of locking bolts 8, which are actuated by pressure medium to extend into locking openings in the bottom and in the mutual profile parts 4.

Der automatische Betätigungsmechanismus ist blockschaltbildartig in Figur 1 dargestellt. Er umfasst einen Druckbehälter 9, der ein Druckluftbehälter sein kann mit ausreichendem Druckluftvorratsvolumen, der mittels eines (nicht dargestellten) Kompressors ständig auf Druck gehalten wird.The automatic operating mechanism is block diagram in FIG FIG. 1 shown. It comprises a pressure vessel 9, which may be a compressed air tank with sufficient compressed air storage volume, which is kept under constant pressure by means of a compressor (not shown).

Außerhalb des Tors ist ein Behälter 10 vorgesehen, der so angeordnet ist, dass er nur bei besonderem Starkregen oder beginnender Überschwemmung mit Wasser vollläuft, und in dem sich ein Schwimmer befindet, der direkt oder über eine Kupplungsstange ein Auslöseventil 11 betätigt, das über Freigabeventile 12, 13 das Aufblasen der aufblasbaren Dichtung 5 sowie das Ausfahren der Riegelbolzen 8 bewirkt.Outside the door, a container 10 is provided, which is arranged so that it runs only in case of heavy rain or incipient flood with water, and in which there is a float which actuates directly or via a coupling rod, a trigger valve 11, the release valves 12th , 13 inflates the inflatable seal 5 and the extension of the locking bolt 8 causes.

Ein pneumatisch oder mechanisch wirkendes Kontrollelement 14 ist mit dem Auslöseventil 11 verbunden und stellt sicher, dass das Aufblasen der aufblasbaren Dichtung 5 und das Ausfahren der Riegelbolzen 8 nur bei geschlossenem Tor erfolgen kann.A pneumatically or mechanically acting control element 14 is connected to the trigger valve 11 and ensures that the inflation of the inflatable seal 5 and the extension of the locking bolt 8 can only be done with the gate closed.

Beim dargestellten Ausführungsbeispiel ist die aufblasbare Dichtung 5 am Sektionaltor 2 angeordnet, und auch die Riegelbolzen 8 sind am Sektionaltor angeordnet, das beweglich ist, und daher bewegliche Schlauchleitungen zu den ortsfest angeordneten pneumatischen Komponenten erfordert. Möglich ist auch eine Umkehrung, nämlich eine Anordnung der aufblasbaren Dichtung an stationären Teilen, und auch der Anordnung der Riegelbolzen an stationären Teilen, die dann in Öffnungen am Versteifungsrahmen oder anderen Bereichen der Segmentplatten ausfahrbar sind.In the illustrated embodiment, the inflatable seal 5 is disposed on the sectional door 2, and also the locking bolts 8 are arranged on the sectional door, which is movable, and therefore requires movable hose lines to the fixedly arranged pneumatic components. Also possible is a reversal, namely an arrangement of inflatable seal on stationary parts, and also the arrangement of the locking bolt on stationary parts, which are then extendable in openings on the stiffening frame or other areas of the segment plates.

Wie vorstehend schon erwähnt, kann auch ein automatisches Schließen des Tors durch eine nicht dargestellte druckmittelbetätigte Vorrichtung vorgesehen sein, wenn sich dieses bei Betätigung des Schwimmers in geöffnetem Zustand befindet.As already mentioned above, an automatic closing of the door can be provided by a pressure-medium-actuated device, not shown, when it is in operation when the float in the open state.
