Description

La présente invention concerne une pompe radiale comprenant un corps dans lequel est monté à rotation un arbre portant au moins un excentrique ou une came de commande et un ou plusieurs pistons disposés radialement autour de l'excentrique ou de la came.The present invention relates to a radial pump comprising a body in which is rotatably mounted a shaft carrying at least one eccentric or a control cam and one or more pistons arranged radially around the eccentric or the cam.

Elle a pour objet une pompe de ce genre qui peut comporter à volonté une, deux ou plusieurs unités de pompage, ce qui permet d'adapter la pompe aux besoins d'utilisation et ainsi de fabriquer cette pompe en grande série, à un prix de revient réduit.It relates to a pump of this kind which can comprise at will one, two or more pumping units, which makes it possible to adapt the pump to the needs of use and thus to manufacture this pump in large series, at a price of returns reduced.

La pompe selon l'invention est caractérisée en ce que le corps de pompe est muni d'une série d'alésages radiaux disposés circonférentiellement autour de la came ou de l'excentrique et en ce que chaque alésage peut recevoir à volonté soit un bouchon d'obturation, soit une unité de pompage indépendante comprenant une chemise extérieure, un piston monté coulissant dans la chemise, un ressort de rappel tendant à appliquer le piston sur la came ou l'ex- centrique, et un clapet de refoulement.The pump according to the invention is characterized in that the pump body is provided with a series of radial bores arranged circumferentially around the cam or of the eccentric and in that each bore can receive at will either a plug of shutter, an independent pumping unit comprising an outer jacket, a piston slidably mounted in the sleeve, a return spring tending to apply the piston on the cam or the centri f q ue, and a discharge valve.

Suivant les besoins, on munit chaque alésage d'un bouchon ou d'une unité de pompage.As required, each bore is fitted with a plug or a pumping unit.

L'unité de pompage ou le bouchon peut être maintenue en position par un jonc métallique. L'élément est ainsi amovible et on peut, si on le désire, remplacer une unité de pompage par un bouchon, ou inversement.The pumping unit or the plug can be held in position by a metal rod. The element is thus removable and it is possible, if desired, to replace a pumping unit with a plug, or vice versa.

En variante, la chemise des unités de pompage et les bouchons comportent des gorges qui, lorsqu'une unité de pompage ou un bouc est mise en place dans un alésage, se trouvent en regard d'une gorge de cet alésage, en constituant une cavité torique, un jonc en matière plastique étant coulé dans la cavité, après la mise en place. Dans ce cas, l'ensemble de la pompe est monté d'une fa çon définitive.Alternatively, the jacket of the pumping units and the caps bear grooves which, when a pumping unit or a goat is placed in a bore, are located opposite a groove of this bore, constituting a toric cavity, a plastic rod being cast in the cavity , after installation. In this case, the entire pump is permanently mounted.

Les différentes cavités toriques sont de préférence reliées à un même conduit d'alimentation débouchant à l'extérieur par une buse de coulée.The various toric cavities are preferably connected to the same supply duct opening to the outside by a pouring nozzle.

On a décrit ci-après, à titre d'exemples non limitatifs, deux mo des de réalisation de la pompe modulaire selon l'invention, avec référence au dessin annexé dans lequel :

  • La Figure 1 est une vue en coupe axiale d'un premier mode de réalisation;
  • La Figure 2 est une vue en coupe transversale d'un détail;
  • La Figure 3 est une vue en coupe axiale d'un second mode de réalisation;
  • La Figure 4 est une vue semblable à la Figure 3 et montre ur. bouchon disposé dans un alésage.
There have been described below, by way of nonlimiting examples, two embodiments of the modular pump according to the invention, with reference to the appended drawing in which:
  • Figure 1 is an axial sectional view of a first embodiment;
  • Figure 2 is a cross-sectional view of a detail;
  • Figure 3 is an axial sectional view of a second embodiment;
  • Figure 4 is a view similar to Figure 3 and shows ur. plug placed in a bore.

Telle qu'elle est représentée aux Figures 1 et 2, la pompe selon l'invention comprend un corps 1 dans lequel est monté à rotation un arbre 2 portant un excentrique 3; sur celui-ci sont montés une bague 4 en bronze et une bague d'usure 5 en acier maintenues par deux rondelles 6.As shown in Figures 1 and 2, the pump according to the invention comprises a body 1 in which is rotatably mounted a shaft 2 carrying an eccentric 3; on this are mounted a ring 4 in bronze and a wear ring 5 in steel held by two washers 6.

L'arbre 2 repose sur deux paliers lisses montés l'un directement dans le carter, l'autre dans une bague 7 formant entretoise. La portion de l'arbre située au delà de cette bague traverse un jcint d'étanchéité 8 et porte une poulie d'entraînement 9.The shaft 2 rests on two plain bearings mounted one directly in the housing, the other in a ring 7 forming a spacer. The portion of the shaft located beyond this ring passes through a sealing jcint 8 and carries a drive pulley 9.

La chambre annulaire 10 qui entoure l'excentrique 3 est reliée à un conduit d'alimentation 11. Elle est par ailleurs reliée par un perçage 12 de l'arbre à une chambre 13 prévue en bout d'arbre dans le corps 1 et assurant le graissage du palier d'extrémité.The annular chamber 10 which surrounds the eccentric 3 is connected to a supply duct 11. It is moreover connected by a bore 12 of the shaft to a chamber 13 provided at the end of the shaft in the body 1 and ensuring the lubrication of the end bearing.

Le corps 1 comporte des alésages radiaux la qui communiquent avec la chambre annulaire 10 et peuvent soit être fermés par des bouchons, soit porter une unité de pompage 31. Dans l'exemple représenté, le corps est muni de deux alésages dont chacun porte une unité de pompage.The body 1 has radial bores la which communicate with the annular chamber 10 and can either be closed by plugs, or carry a pumping unit 31. In the example shown, the body is provided with two bores, each of which carries a unit pumping.

Chaque unité de porpage comprond une chemise 14 qui est engagée dans l'un des alésages la. Elle peut être en butée sur la bague 7 ou présenter un épaulement en butée sur le corps de pompe 1. Sa partie cylindrique de diamètre réduit est munie d'une première gorge contenant un joint torique d'étanchéité 15 et une deuxième gorge disposée en regard d'une deuxième gorge complémentaire prévue dans l'alésage la. L'ensemble des deux gorges constitue une cavité torique qui est reliée par un conduit 16 à une buse de coulée 17. Après mise en place des chemises 14 des unités de pompage dans leurs alésages, une matière plastique a été coulée dans la buse 17; cette matière plastique a rempli les cavités toriques et a formé dans chacune d'elles un jonc 18 qui fixe de manière définitive la chemise 14 dans son alésage.Each paging unit includes a jacket 14 which is engaged in one of the bores la. It can be in abutment on the ring 7 or have a shoulder in abutment on the pump body 1. Its cylindrical part of reduced diameter is provided with a first groove containing an O-ring seal 15 and a second groove arranged opposite a second complementary groove provided in the bore la. The assembly of the two grooves constitutes a toric cavity which is connected by a conduit 16 to a pouring nozzle 17. After fitting the jackets 14 of the pumping units in their bores, a plastic material was poured into the nozzle 17; this plastic material filled the toroidal cavities and formed in each of them a rod 18 which definitively fixes the jacket 14 in its bore.

Dans la chemise 14 est monté coulissant un piston 19 constitué par un tube borgne dont la face fermée est en appui sur l'excentrique 3. La partie cylindrique du piston comporte des trous 20 découverts ou non suivant la position du piston et propres à mettre la chambre 10 en communication avec l'intérieur du piston.In the sleeve 14 is slidably mounted a piston 19 consisting of a blind tube whose closed face is supported on the eccentric 3. The cylindrical part of the piston has holes 20 uncovered or not depending on the position of the piston and adapted to put chamber 10 in communication with the interior of the piston.

A l'intérieur du piston 19 est engagé un ressort de rappel 21 qui est interposé entre un compensateur de volume 33 en appui sur le fond du piston et une bague 22 immobilisée dans la chemise 14 par un jonc métallique 23.Inside the piston 19 is engaged a return spring 21 which is interposed between a volume compensator 33 bearing on the bottom of the piston and a ring 22 immobilized in the jacket 14 by a metal rod 23.

La bague 22 est percée d'un trou axial 24 et sa face opposée au piston 19 forme siège pour un clapet 25 pouvant obturer le trou 24. Ce clapet est mobile à l'intérieur d'une ouverture 26 ménagée à la fraise dans un embout de sortie 27 qui est emmanché dans la chemise 14 et est immobilisé en position par une goupille 28. Le clapet 25 est soumis aux actions antagonistes de la pression à l'intérieur du piston et d'un ressort de rappel 29 prenant appui sur l'embout 27.The ring 22 is pierced with an axial hole 24 and its face opposite the piston 19 forms a seat for a valve 25 which can close the hole 24. This valve is movable inside an opening 26 made with a milling cutter in a nozzle outlet 27 which is fitted into the jacket 14 and is immobilized in position by a pin 28. The valve 25 is subjected to the opposing actions of the pressure inside the piston and of a return spring 29 bearing on the end cap 27.

Dans le mode de réalisation de la Figure 3, la chemise 14 est immobilisée par un jonc métallique 30. Il est ainsi possible, si on le désire, de retirer la chemise et de la remplacer par un bouchon 32, comme le montre la Figure 4. Par ailleurs, la chemise 14 ne comporte pas d'épaulement et est en butée contre la bague entretoise 7.In the embodiment of Figure 3, the jacket 14 is immobilized by a metal rod 30. It is thus possible, if desired, to remove the jacket and replace it with a plug 32, as shown in Figure 4 Furthermore, the jacket 14 does not have a shoulder and is in abutment against the spacer ring 7.

Il va de soi que la présente invention ne doit pas être limitée aux modes de réalisation décrits et représentés mais en couvre, au contraire, toutes les variantes. C'est ainsi, en particulier, que l'arbre 2 pourrait porter deux ou plusieurs excentriques 3 actionnant chacun leurs propres pistons.It goes without saying that the present invention should not be limited to the embodiments described and shown, but on the contrary covers all variants. This is how, in particular, that the shaft 2 could carry two or more eccentrics 3 each actuating their own pistons.
