Description
Pompe hydraulique. La présente invention a pour objet. un pompe hydraulique à barillet dans laquelle le liquide, admis d'un côté du barillet, dans une chambre d'aspiration, passe à travers des liiston#, se déplaçant dans des cylindres mon- Ii' -# barillet et est refoulé de l'autre côté du barillet.
Cette pompe est caractérisée en ce que @lcë clapets plats r. fonctionnement automa tique sont prévus dans lesdits pistons et sont commandés par dépression.
Le dessin représente schématiquement, à titre d'exemple, une forme d'exécution de la pompe faisant l'objet de la présente inven tion.
La fig. 1 est une coupe axiale. L < t fi<I>n</I> ,,,. 2? en est une coupe transversale simplifiée et à plus petite échelle.
La, pompe comporte un carter 1, dc. forme générale cylindrique dont un des fonds ' présente un palier 3 pour un arbre moteur 1.<B>Cr-</B> dernier est également supporté, en son extrémité 5, dans un palier 6 formé à l'extré- iriité d'un tirant 7 traversant l'autre fond 8 (lu carter. L'extrémité 9 du tirant 7 faisant #4aillic par rapport au fond 8 est filetée et coopère avec un écrou<B>10</B> s'appuyant sur le fond 8.
A son autre extrémité, le tirant 7 forme le rebord 11 contre lequel prend appui tin barillet 1.2 percé d'un certain nombre d'alé- sages. Dans chacun de ces alésages est placé un cylindre 13 dont l'axe est parallèle à celui dus paliers 3 et 5. Ce cylindre présente une portée conique 14 qui, en coopération avec l'arête vive du bord de l'alésage, assure l'étan chéité entre le cylindre et le barillet à l'égard du liquide se trouvant dans la. chambre adja cente 1.6.
Les cylindres 13 prennent appui sur le fond 8, non pas directement, mais par l'in termédiaire d'un élément élastique 17. La partie élargie 18 du cylindre 1.3 limite une chambre 19 communiquant par des lumières \?() avec la chambre de refoulement 16 de la pompe. Un clapet plat ?1, soumis à l'action d'un ressort ??, est interposé entre la chambre 19 et la chambre 23 limitée par la. chemise 24 du cylindre. Dans celui-ci peut se déplacer, d'une manière étanche, un piston tubulaire ?5 présentant un canal longitudinal 26.
Celui-ci débouche dans une chambre 27 et la commu nication entre le canal 26 et la chambre 27 est contrôlée par un clapet plat 28, libre ou sou mis à l'action d'un très léger ressort (non re présenté). La. chambre 2 7 communique avec la chambre ?3 par une ouverture 29 pratiquée sur le fond du piston. Le canal 26 débouche dans la chambre d'aspiration 3C> par une lu mière 31. Le piston 25 présente une tête 32 dans laquelle est pratiquée une cavité sphéri que<B>'03</B> servant au logement d'une bille tron quée 34. Un ressort 35 est interposé entre, d'une part, le barillet 1? et, d'autre part, la tête 32. Les billes 34 prennent appui, par leur face plane 36, sur une butée à billes 37 dont.
l'axe forme un certain angle avec celui des paliers 3 et 6, un plateau 38 étant formé ,sur l'arbre 4 pour recevoir cette butée. Une tubu lure d'aspiration<B>39</B> débouche tangentiellement dans la chambre 30.
Le fonctionnement de cette pompe est le suivant: La rotation -des organes enfermés dans la chambre 30 met le liquide contenu dans cette chambre en rotation suivant le sens montré par la flèche f sur la fig. 2. Le liquide contenu dans la canalisation 39, dirigée tan gentiellement à la trajectoire des filets liquides dans la chambre 30, est donc entraîné, ce qui correspond à la création d'une certaine dépression dans la canalisation 39.
La rota tion du plateau 38 et de la butée 37 imprime un mouvement de va-et-vient aux pistons 25: renfoncement des pistons 25 est provoqué di rectement par l'action de la butée 3 7 s'exer çant par l'intermédiaire -des billes 34; le re tour des pistons s'effectue sous l'action des ressorts 35. Pendant l'enfoncement des pis tons 25, le liquide contenu dans la chambre 23 ne peut s'échapper par le canal 26, en rai son de la fermeture du clapet d'aspiration 28.
Le liquide contenu dans la chambre 23 est clone mis sous pression jusqu'à ce que celle-ci soit suffisante pour vaincre l'action du ressort 22 et le liquide est alors refoulé, sous pression,, dans l'a chambre de refoulement 16 et, de là, par les lumières 40 et le canal 41 pratiqués dans le tirant 7, vers la canalisation de re foulement. Pendant la course de retour du piston 25, le liquide contenu dans la chambre 19 et la chambre ,de refoulement 16 ne peut rétrograder, en raison de la fermeture -du cla pet de refoulement 21.
La dépression créée dans la chambre 23 soulève le clapet 28 et le liquide contenu dans la chambre d'admission 30 a accès dans la chambre 23 par la lumière 31 et le canal 26. Lorsque le piston 25 s'en fonce à nouveau, le clapet 28 est appliqué sur -son siège, le liquide contenu dans la chambre 23 est comprimé et le cycle recommence. On remarquera que le liquide ne subit pas d'in version dans le sens de son mouvement. La section de passage du liquide dans le piston 25 est considérable, puisque le canal 26 peut avoir un diamètre voisin de celui du pis- ton.
L'application de clapets plats tels que le clapet 28 permet le contrôle de la communica tion entre le côté admission et le côté refoule ment ,de la pompe sans que la section du pas sage du liquide en soit diminuée.
Le matelas élastique 17 assure la. portée simultanée des joints entre le barillet et les cylindres lorsque leur nombre est supérieur à trois, et cela sans sujétion onéreuse de fabri cation. L'appui d'une partie conique des cylin dres 13 contre une arêté vive du barillet 1 2 constitue une solution simple de l'étanchéité du montage de ces organes. La dépression créée dans la tubulure d'aspiration 39 par le mouvement -du liquide dans la chambre 30 permet d'étendre le domaine d'application de la pompe en rendant possible l'existence d'une dénivellation importante entre celle-ci et sa bâche d'alimentation, sans introduire de ris ques de désamorçage.
La pompe décrite a l'avantage d'être de construction simple, de bon rendement et d'avoir un fonctionnement particulièrement doux, sujet qu'à de faibles vibrations.
Hydraulic pump. The object of the present invention is. a hydraulic barrel pump in which the liquid, admitted from one side of the barrel, into a suction chamber, passes through liiston #, moving in cylinders my- Ii '- # barrel and is discharged from the other side of the barrel.
This pump is characterized in that @ lcë flat valves r. automatic operation are provided in said pistons and are controlled by vacuum.
The drawing shows schematically, by way of example, an embodiment of the pump forming the subject of the present invention.
Fig. 1 is an axial section. L <t fi <I> n </I> ,,,. 2? is a simplified cross section on a smaller scale.
The pump has a housing 1, dc. generally cylindrical shape, one of the ends of which has a bearing 3 for a motor shaft 1. The latter is also supported, at its end 5, in a bearing 6 formed at the end of a tie rod 7 passing through the other base 8 (see casing. The end 9 of the tie rod 7 making # 4aillic relative to the base 8 is threaded and cooperates with a nut <B> 10 </B> resting on the base 8 .
At its other end, the tie rod 7 forms the flange 11 against which bears a barrel 1.2 pierced with a number of bore holes. In each of these bores is placed a cylinder 13 whose axis is parallel to that of the bearings 3 and 5. This cylinder has a conical bearing 14 which, in cooperation with the sharp edge of the edge of the bore, ensures the sealing between the cylinder and the barrel with respect to the liquid in the. room adja cente 1.6.
The cylinders 13 are supported on the bottom 8, not directly, but via an elastic element 17. The widened part 18 of the cylinder 1.3 limits a chamber 19 communicating by openings \? () With the chamber of discharge 16 of the pump. A flat valve? 1, subjected to the action of a spring ??, is interposed between the chamber 19 and the chamber 23 limited by the. cylinder liner 24. Therein can move in a sealed manner a tubular piston 5 having a longitudinal channel 26.
This opens into a chamber 27 and the communication between the channel 26 and the chamber 27 is controlled by a flat valve 28, free or subjected to the action of a very light spring (not shown). Chamber 27 communicates with chamber 3 through an opening 29 in the bottom of the piston. The channel 26 opens into the suction chamber 3C> through a light 31. The piston 25 has a head 32 in which is formed a spherical cavity <B> '03 </B> serving to accommodate a trunn ball. quée 34. A spring 35 is interposed between, on the one hand, the barrel 1? and, on the other hand, the head 32. The balls 34 bear, by their flat face 36, on a ball stop 37 of which.
the axis forms a certain angle with that of the bearings 3 and 6, a plate 38 being formed, on the shaft 4 to receive this stop. A <B> 39 </B> suction pipe opens tangentially into chamber 30.
The operation of this pump is as follows: The rotation of the members enclosed in the chamber 30 causes the liquid contained in this chamber to rotate in the direction shown by the arrow f in FIG. 2. The liquid contained in the pipe 39, directed tangentially to the path of the liquid streams in the chamber 30, is therefore entrained, which corresponds to the creation of a certain depression in the pipe 39.
The rotation of the plate 38 and of the stop 37 induces a reciprocating movement on the pistons 25: recess of the pistons 25 is caused directly by the action of the stop 3 7 exerted by the intermediary - balls 34; the return of the pistons is effected by the action of the springs 35. While driving in the pis tons 25, the liquid contained in the chamber 23 cannot escape through the channel 26, due to the closing of the valve. suction 28.
The liquid contained in the chamber 23 is cloned pressurized until the latter is sufficient to overcome the action of the spring 22 and the liquid is then discharged, under pressure, into the delivery chamber 16 and , from there, through the slots 40 and the channel 41 made in the tie rod 7, to the return pipe. During the return stroke of the piston 25, the liquid contained in the chamber 19 and the discharge chamber 16 cannot downshift, due to the closing of the discharge valve 21.
The vacuum created in the chamber 23 lifts the valve 28 and the liquid contained in the intake chamber 30 has access to the chamber 23 through the opening 31 and the channel 26. When the piston 25 sinks again, the valve 28 is applied to its seat, the liquid contained in the chamber 23 is compressed and the cycle begins again. It will be noted that the liquid does not undergo inversion in the direction of its movement. The section of passage of the liquid in the piston 25 is considerable, since the channel 26 may have a diameter close to that of the piston.
The application of flat valves such as the valve 28 allows the control of the communication between the inlet side and the discharge side, of the pump without the section of the passage wise of the liquid being reduced.
The elastic mattress 17 ensures the. simultaneous bearing of the seals between the barrel and the cylinders when their number is greater than three, and this without costly manufacturing constraints. The support of a conical part of the cylinders dres 13 against a sharp edge of the barrel 1 2 constitutes a simple solution of the sealing of the assembly of these members. The depression created in the suction pipe 39 by the movement of the liquid in the chamber 30 makes it possible to extend the field of application of the pump by making possible the existence of a significant difference in level between the latter and its tank. power supply, without introducing any risk of defusing.
The pump described has the advantage of being of simple construction, of good efficiency and of having a particularly smooth operation, subject only to low vibrations.
