Abstract

In an oil filter in which an annular filter insertion unit (2) can be removed geodetically upwards from a pot-shaped filter housing, there is to be provision for flowing back of the oil present in the filter tube space (3) into an outlet channel (10) which opens when the filter insert is removed to occur in a simplified fashion with respect to the prior art. For this purpose, a pin (11) which protrudes out in the axial direction is to be formed at the lower end plate (5) of the annular filter insert (2) and when the annular filter insert (2) is fitted on the said pin (11) is to project in a sealing fashion into the opening of the outflow channel (10) and, in addition, fixing means (13) are to be provided on the annular filter insert (2) and the filter housing (1) and are to permit axial insertion of the filter insert only in one position which centres the pin (11) with respect to the opening of the outflow channel (10). <IMAGE>

Description

Die Erfindung betrifft ein Ölfilter zum Reinigen von Schmieröl nach dem Oberbegriff des Patentanspruchs 1The invention relates to an oil filter for cleaning Lubricating oil according to the preamble of patent claim 1

Ein solches Schmierölfilter ist beispielsweise aus DE 34 09 219 A1 bekannt.Such a lubricating oil filter is for example from DE 34 09 219 A1 known.

Gegenüber diesem bekannten Filter besteht die Aufgabe der Erfindung darin, den Verschluß des mit dem Roh­ raum des Filtergehäuses verbindbaren Ableitungskana­ les konstruktiv zu vereinfachen.The task is compared to this known filter the invention in the closure of the with the raw Space of the filter housing connectable drainage canals to simplify the design.

Gelöst wird diese Aufgabe durch eine Ausgestaltung des gattungsgemäßen Filters nach den kennzeichnenden Merkmalen des Patentanspruchs 1.This task is solved by a configuration of the generic filter according to the characteristic Features of claim 1.

Mit der Ausführung nach Anspruch 2 soll ein automati­ sches Öffnen des zusätzlichen Ableitungskanales am unteren Ende des Filtergehäuses erreicht werden.With the embodiment according to claim 2 is an automati opening of the additional discharge duct on lower end of the filter housing can be reached.

Weitere zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der übrigen Unteransprüche.Further expedient refinements of the invention are the subject of the remaining subclaims.

Ein Ausführungsbeispiel ist in der Zeichnung darge­ stellt. Es zeigen An embodiment is shown in the drawing poses. Show it  

Fig. 1 einen Längsschnitt durch ein Öl­ filtergehäuse, Fig. 1 a longitudinal section through the filter housing, an oil,

Fig. 2 einen Schnitt durch das Filterge­ häuse nach Linie II-II. Fig. 2 shows a section through the Filterge housing along line II-II.

In das Ölfiltergehäuse 1 ist ein ringförmiger Filter­ einsatz 2 eingesetzt. Der Filtereinsatz 2 trennt das Filtergehäuse in einen Rohraum 3 und einen Reinraum 4. Entsprechend den eingetragenen Pfeilen wird der Rohraum 3 mit Öl versorgt, das durch den Einsatz ra­ dial hindurchströmt und den Reinraum 4 gemäß den dor­ tigen Pfeilen verläßt.In the oil filter housing 1 , an annular filter insert 2 is used. The filter insert 2 separates the filter housing into a tube space 3 and a clean room 4 . According to the arrows entered, the raw space 3 is supplied with oil which flows through the insert ra dial and leaves the clean room 4 in accordance with the arrows there.

Zur Trennung zwischen Reinraum 4 und Rohraum 3 ist die untere Endscheibe 5 des Filtereinsatzes mit einem zentralen Rohr 6 verbunden, das in einen zylindri­ schen Kanal des Filtergehäuses hineinragt, gegen den es mit Hilfe eines radialen Dichtringes 7 gedichtet ist.To separate between clean room 4 and tube space 3 , the lower end plate 5 of the filter insert is connected to a central tube 6 which protrudes into a cylindrical channel of the filter housing, against which it is sealed by means of a radial sealing ring 7 .

Am oberen Ende des Ringfiltereinsatzes 2 ist an die dortige Endscheibe 8 ein Bypassventil 9 angeformt bzw. an dieser angeordnet.At the upper end of the ring filter insert 2 , a bypass valve 9 is integrally formed on the end disk 8 there or is arranged thereon.

Ein aus dem Rohraum 3 des Filtergehäuses 1 getrennt herausführender Abflußkanal 10 ist durch einen an die untere Endscheibe 5 des Ringfilterelementes 2 ange­ formten Zapfen 11, der mit einer Radialdichtung 12 versehen ist, dicht verschlossen. A from the tube 3 of the filter housing 1 leading outflow channel 10 is sealed by a to the lower end plate 5 of the ring filter element 2 molded pin 11 , which is provided with a radial seal 12 , sealed.

Damit beim Einsetzen des Ringfilterelementes 2 der Zapfen 11 in die Öffnung des Abflußkanales 10 gezielt eindringen kann, sind das Filtergehäuse 1 einerseits und der ringförmige Filtereinsatz 2 andererseits mit axial ineinandergreifenden aufeinander abgestimmten Nut- und Federmitteln 13 versehen.So that when inserting the ring filter element 2 the pin 11 can penetrate into the opening of the drain channel 10 , the filter housing 1 on the one hand and the annular filter insert 2 on the other hand are provided with axially interlocking, coordinated tongue and groove means 13 .

Verschlossen wird das Filtergehäuse mit einem auf­ schraubbaren Deckel 14. Über einen Schnappverschluß 15 ist in Umfangsrichtung drehbar jedoch axial fi­ xiert der Ringfiltereinsatz 2 an dem Deckel 14 befe­ stigt. Auf diese Weise wird beim Abschrauben des Deckels 14 der Ringfiltereinsatz derart axial nach oben verschoben, daß die Öffnung des Abflußkanales 10 durch den Zapfen 11 freigegeben wird.The filter housing is closed with a screw-on cover 14 . About a snap lock 15 is rotatable in the circumferential direction but axially fi xed the ring filter insert 2 on the cover 14 BEFE Stigt. In this way, when the cover 14 is unscrewed, the ring filter insert is displaced axially upward in such a way that the opening of the drainage channel 10 is released by the pin 11 .
