Le dispositif 10 de branchement d'alimentation pour système à pression de fluide qui est représenté sur les figures 1 à 5 comporte essentiellement une entrée d'alimentation 12 dont le corps 14, sensiblement tubulaire d'axe X-X, est solidaire d'un organe hydraulique récepteur (non représenté) et un raccord 16 prévu pour être fixé à l'extrémité d'une The supply connection device 10 for a fluid pressure system which is shown in FIGS. 1 to 5 essentially comprises a supply inlet 12 whose body 14, substantially tubular with axis XX, is integral with a hydraulic member receiver (not shown) and a connector 16 intended to be fixed to the end of a
canalisation d'alimentation (non représentée). supply line (not shown).
On a choisi de décrire le dispositif 10 pour le cas o le raccord 16 est considéré comme étant mobile par rapport à l'entrée d'alimentation 12 mais on pourra bien entendu, sans sortir du cadre de l'invention, réaliser un tel dispositif dans lequel le raccord 16 est fixe et dans lequel le corps 14 de l'entrée d'alimentation 12 est branché à l'extrémité d'une canalisation souple et étant ainsi relié à un organe récepteur indirectement. We have chosen to describe the device 10 for the case where the connector 16 is considered to be movable relative to the supply inlet 12 but it will of course be possible, without departing from the scope of the invention, to produce such a device in which the connector 16 is fixed and in which the body 14 of the supply inlet 12 is connected to the end of a flexible pipe and thus being connected to a receiving member indirectly.
Le raccord 16 selon l'invention comporte essentielle- The connector 16 according to the invention essentially comprises-
ment à l'avant, c'est-à-dire à gauche en considérant la figure 1, une tête 18 qui est destinée à être reçue axialement dans le lying at the front, that is to say on the left considering FIG. 1, a head 18 which is intended to be received axially in the
corps 14 d'entrée d'alimentation 12, et à l'arrière, c'est-à- supply inlet body 14 12, and at the rear, that is
dire à droite en considérant la figure 1, un embout de liaison pour le raccordement à la canalisation d'alimentation par say on the right considering Figure 1, a connecting piece for connection to the supply line by

Le raccord 16 est sensiblement tubulaire et comporte un canal interne 22 qui débouche à l'extrémité axiale avant 24 The connector 16 is substantially tubular and has an internal channel 22 which opens at the front axial end 24
du raccord 16 dans l'entrée d'alimentation 12. of connector 16 in supply inlet 12.
L'entrée d'alimentation 12 se présente sous la forme The power input 12 is in the form
d'un cylindre étagé.of a stepped cylinder.
De manière connue, le raccord d'alimentation 16 est susceptible d'occuper une position engagée axialement, qui est représentée sur la figure 3, dans laquelle il établit une communication étanche entre la canalisation d'alimentation et In known manner, the supply fitting 16 is capable of occupying an axially engaged position, which is shown in FIG. 3, in which it establishes a sealed communication between the supply pipe and
l'organe récepteur.the receiving organ.
A cet effet, un premier joint d'étanchéité 26 qui est agencé dans un logement annulaire radial 28, ici en forme de rainure, de l'extrémité axiale avant 24 du raccord 16 et qui coopère avec une première paroi cylindrique 30 de l'entrée For this purpose, a first seal 26 which is arranged in an annular radial housing 28, here in the form of a groove, of the front axial end 24 of the connector 16 and which cooperates with a first cylindrical wall 30 of the inlet
d'alimentation 12.supply 12.
Une purge 32 est réalisée sous la forme d'un trou de purge qui est percé transversalement dans le corps 14 de l'entrée d'alimentation 12 de manière à déboucher dans l'entrée d'alimentation 12, en arrière de la première surface cylindrique 30 afin que, lorsque le raccord 16 est en position engagée axialement, le joint d'étanchéité 26 sépare de manière étanche le canal interne 22 du raccord 16 et l'organe récepteur A purge 32 is produced in the form of a purge hole which is drilled transversely in the body 14 of the supply inlet 12 so as to open into the supply inlet 12, behind the first cylindrical surface 30 so that, when the connector 16 is in the axially engaged position, the seal 26 seals the internal channel 22 of the connector 16 and the receiving member
d'une part de la purge 32 d'autre part. on the one hand of the purge 32 on the other hand.
Ainsi, la purge 32 débouche en 33 dans une deuxième paroi cylindrique 34 de l'entrée d'alimentation 12 qui est de diamètre supérieur à la première paroi cylindrique 30 et qui Thus, the drain 32 opens at 33 into a second cylindrical wall 34 of the supply inlet 12 which is of greater diameter than the first cylindrical wall 30 and which
est agencée axialement en arrière par rapport à celle-ci. is arranged axially behind it.
Un second joint d'étanchéité 36 est agencé dans un logement annulaire 38, ici en forme de rainure, qui est taillé radialement dans la périphérie externe 40 d'un segment cylindrique 42 du raccord 16 dont le diamètre est sensiblement égal au diamètre de la seconde paroi cylindrique 34 de l'entrée A second seal 36 is arranged in an annular housing 38, here in the form of a groove, which is cut radially in the external periphery 40 of a cylindrical segment 42 of the connector 16 whose diameter is substantially equal to the diameter of the second cylindrical wall 34 of the entrance
12 et qui participe au guidage du raccord 16 dans l'entrée 12. 12 and which participates in guiding the connector 16 in the inlet 12.
Le joint d'étanchéité 36 est agencé entre l'extrémité débouchante 33 de la purge 32 et l'extrémité débouchante 44 de The seal 36 is arranged between the through end 33 of the drain 32 and the through end 44 of
l'entrée 12.entrance 12.
De manière connue, et comme cela est représenté sur les figures 2 et 3, le raccord 16 est maintenu en position engagée axialement à l'intérieur de l'entrée 12 par une goupille, ou broche, transversale 48 en forme de U dont les deux branches parallèles 49 sont engagées dans un logement transversal 46 du corps 14 de l'entrée d'alimentation 12. Les deux branches 49 de la goupille 48 coopèrent avec une première gorge annulaire 50 (figure 1) qui est agencée le raccord 16, en In known manner, and as shown in FIGS. 2 and 3, the connector 16 is held in the axially engaged position inside the inlet 12 by a transverse pin, or pin 48, U-shaped, the two of which parallel branches 49 are engaged in a transverse housing 46 of the body 14 of the supply inlet 12. The two branches 49 of the pin 48 cooperate with a first annular groove 50 (FIG. 1) which is arranged the connector 16, in
arrière du segment cylindrique de guidage 42. rear of the guide cylindrical segment 42.
Conformément aux enseignements de l'invention, le raccord 16 peut occuper une seconde position partiellement reculée, qui est représentée sur la figure 1 et dans laquelle le raccord 16 est partiellement retiré axialement par rapport à In accordance with the teachings of the invention, the connector 16 can occupy a second partially retracted position, which is shown in FIG. 1 and in which the connector 16 is partially withdrawn axially with respect to
sa position engagée dans l'entrée d'alimentation 12. its position engaged in the feed inlet 12.
Le raccord 16 est maintenu dans cette seconde position partiellement reculée par la goupille 48 qui coopère cette fois-ci avec une seconde gorge annulaire 52, similaire à la première gorge 50, mais agencée entre la première gorge 50 et The connector 16 is held in this second position partially retracted by the pin 48 which this time cooperates with a second annular groove 52, similar to the first groove 50, but arranged between the first groove 50 and
le segment cylindrique de guidage 42. the cylindrical guide segment 42.
Dans cette seconde position partiellement reculée, le raccord 16 est retiré axialement de sorte que le premier joint d'étanchéité 26 ne porte plus sur la première surface cylindrique 30 de l'entrée d'alimentation 12 et qu'ainsi la communication soit établie entre l'organe récepteur et la purge 32 d'une part, mais également entre le canal interne 22 du In this second partially retracted position, the connector 16 is removed axially so that the first seal 26 no longer bears on the first cylindrical surface 30 of the supply inlet 12 and that thus communication is established between the receiver and the purge 32 on the one hand, but also between the internal channel 22 of the
raccord 16 et la purge 32.connection 16 and drain 32.
Toutefois, dans cette seconde position partiellement reculée, le second joint d'étanchéité 36 demeure en contact avec la seconde surface cylindrique 34 afin que le fluide ne However, in this second partially retracted position, the second seal 36 remains in contact with the second cylindrical surface 34 so that the fluid does not
puisse pas s'évacuer ailleurs que par la purge 32. cannot be evacuated elsewhere than by purge 32.
Ainsi, on peut injecter à l'intérieur de l'organe récepteur du fluide sous pression par le raccord 16 et expulsé ainsi de l'air qui serait resté emprisonné à l'intérieur de l'organe récepteur et qui pourrait nuire au bon fonctionnement Thus, one can inject inside the receiving member pressurized fluid through the connector 16 and thus expelled air which would have remained trapped inside the receiving member and which could impair the proper functioning
de celui-ci.of it.
Selon une autre caractéristique de l'invention, la seconde gorge 52, qui est agencée axialement en avant de la première gorge 50, comporte une face axiale arrière 54 biseautée de manière que, le raccord 16 étant en position partiellement reculée et la goupille 48 étant en position engagée transversalement, et sous l'effet d'un effort axial exercé vers l'avant sur le raccord 16, la face arrière biseauté 54 de la seconde gorge 52 tend à provoquer l'écartement radial des branches 49 de la goupille 48 de manière à autoriser le passage du raccord 16 vers sa position engagée dans laquelle les branches 49 de la goupille 48 retombent élastiquement au According to another characteristic of the invention, the second groove 52, which is arranged axially in front of the first groove 50, has a rear axial face 54 bevelled so that, the connector 16 being in the partially retracted position and the pin 48 being in the transversely engaged position, and under the effect of an axial force exerted forwards on the connector 16, the bevelled rear face 54 of the second groove 52 tends to cause the radial separation of the branches 49 of the pin 48 of so as to allow the passage of the connector 16 to its engaged position in which the branches 49 of the pin 48 fall elastically to the
fond de la première gorge 50.bottom of the first groove 50.
Ainsi, on pourra, lors du branchement du raccord 16, engager la goupille 48 dans la seconde gorge 52 du raccord 16, injecter du fluide sous pression dans l'organe récepteur de manière à purger celui-ci et, la purge étant achevée, établir une communication étanche entre la canalisation d'alimentation et l'organe récepteur simplement en poussant axialement le Thus, when connecting the connector 16, it is possible to engage the pin 48 in the second groove 52 of the connector 16, inject pressurized fluid into the receiving member so as to purge the latter and, the purging being completed, establish tight communication between the supply line and the receiver simply by pushing the
raccord 16 vers l'avant.connection 16 forwards.
Cette disposition permet ainsi d'éviter de manipuler la goupille 48, voire de la retirer complètement, ce qui évite que sous l'effet de la pression accumulée dans l'organe récepteur lors de l'opération de purge, le raccord 16 ne recul et ne se dégage axialement totalement de l'entrée This arrangement thus makes it possible to avoid manipulating the pin 48, or even to withdraw it completely, which avoids that under the effect of the pressure accumulated in the receiving member during the purging operation, the connector 16 does not recoil and does not emerge completely axially from the entrance
d'alimentation 12.supply 12.
Selon une autre caractéristique de l'invention, la goupille transversale 48 peut occuper une seconde position intermédiaire dans laquelle elle est partiellement retirée transversalement de manière qu'elle coopère avec le raccord 16 According to another characteristic of the invention, the transverse pin 48 can occupy a second intermediate position in which it is partially withdrawn transversely so that it cooperates with the connector 16
par une portion extrême élargie 56. by an enlarged end portion 56.
Dans cette position de la goupille 48, le raccord 16 est libre de passer de sa position engagée axialement vers sa In this position of the pin 48, the connector 16 is free to pass from its axially engaged position towards its
position partiellement reculée, et inversement. partially retracted position, and vice versa.
Toutefois, dans cette seconde position intermédiaire de la goupille 48, le raccord 16 ne peut pas se dégager axialement vers l'arrière davantage que sa position partiellement reculée car il est prévu que la portion élargie 56 de la goupille 48 soit d'un écartement tel qu'elle vienne en butée contre la face d'extrémité axiale arrière 58 du segment However, in this second intermediate position of the pin 48, the connector 16 cannot disengage axially towards the rear more than its partially retracted position because it is provided that the enlarged portion 56 of the pin 48 is of such spacing that it abuts against the rear axial end face 58 of the segment
cylindrique de guidage 42.guide cylinder 42.
Ainsi, il est possible de faire passer le raccord 16 de sa position axiale engagée vers sa position intermédiaire partiellement retirée sans pour autant autorisé son Thus, it is possible to pass the connector 16 from its axial position engaged towards its partially withdrawn intermediate position without however allowing its
désengagement complet.complete disengagement.
Ainsi, on pourra par exemple faire chuter la pression régnant dans l'organe récepteur au travers de l'orifice de Thus, we can for example drop the pressure prevailing in the receiving member through the orifice
purge 32.purge 32.
Un collet radial cylindrique arrière 60, agencé entre la tête 18 et l'embout de raccordement 20 du raccord 16 coopère avec une surface cylindrique arrière 62 de l'entrée d'alimentation 12 pour participer au guidage du raccord 16. Ce A rear cylindrical radial collar 60, arranged between the head 18 and the connection end piece 20 of the connector 16 cooperates with a rear cylindrical surface 62 of the supply inlet 12 to participate in guiding the connector 16. This
collet délimite la gorge.collar delimits the throat.
Ainsi qu'on l'aura compris le joint 36 réalise As we will have understood the joint 36 realizes
également l'étanchéité à l'air (figure 1). also airtightness (Figure 1).
