Description

AGENCEMENT POUR RACCORDER UNE PREMIERE CANALISATION A UNE SECONDEARRANGEMENT FOR CONNECTING A FIRST LINE TO A SECOND

CANALISATIONPIPELINE

DESCRIPTION DOMAINE TECHNIQUE L'invention concerne un agencement pour raccorder une première canalisation à une seconde canalisation. On a représenté à la figure 1 un circuit de retour d'huile lubrification d'un turbo compresseur réalisé conformément aux enseignements de l'art antérieur. Le turbo compresseur 10 comporte un circuit interne (non représenté) de lubrification qui communique avec le circuit de lubrification du moteur 12 du véhicule. Il comporte à cet effet un canal d'arrivée d'huile (non représenté) et une canalisation de retour d'huile supérieure 14 d'évacuation de l'huile vers une canalisation réalisée dans le carter 16 du moteur que l'on a représenté à la figure 1 par son orifice d'entrée 18. Pour relier la canalisation de retour d'huile supérieure 14 au carter 16, le circuit de retour d'huile comporte une canalisation de retour d'huile inférieure qui est réalisée en un matériau métallique, dont une première extrémité supérieure 20s est reliée à la canalisation de retour d'huile supérieure 14 par l'intermédiaire d'un système à brides 22 et dont la deuxième extrémité inférieure 20i comporte un embout qui est introduit dans l'orifice d'entrée 18 de la canalisation.  TECHNICAL FIELD The invention relates to an arrangement for connecting a first pipe to a second pipe. There is shown in Figure 1 a lubricating oil return circuit of a turbo compressor made in accordance with the teachings of the prior art. The turbo compressor 10 has an internal lubrication circuit (not shown) that communicates with the engine lubrication circuit 12 of the vehicle. It comprises for this purpose an oil inlet duct (not shown) and an upper oil return line 14 for discharging the oil to a duct formed in the casing 16 of the motor that has been shown. in Figure 1 by its inlet 18. To connect the upper oil return line 14 to the housing 16, the oil return circuit comprises a lower oil return pipe which is made of a metallic material , whose first upper end 20s is connected to the upper oil return line 14 via a flange system 22 and whose second lower end 20i has a nozzle which is introduced into the inlet orifice 18 of the pipeline.

Un tel agencement présente de nombreux inconvénients. L'assemblage de la canalisation de retour d'huile supérieure 14 à la canalisation de retour d'huile inférieure 20 est encombrant. Le nombre de pièce est important. Un temps d'assemblage élevé est requis pour les assembler. Enfin, cette solution pose des problèmes d'accessibilité des vis pour le démontage, notamment en après-vente. La présente invention a pour objet un agencement pour raccorder une première canalisation à une seconde canalisation qui remédie à ces inconvénients. Ces buts sont atteints par le fait que la première canalisation comporte une collerette dans laquelle est montée un joint torique et en ce que la seconde canalisation comporte une partie de diamètre agrandi dans laquelle la collerette et le joint torique de la première canalisation se loge. Grâce à ces caractéristiques le nombre de pièces est réduit. En particulier, il n'y a pas de vis ni de bride. La première canalisation est en un seul composant (suppression des brides). La fabrication des pièces est plus simple et plus facile. Leur coût est diminué. L'assemblage est rapide et facile. Selon un avantage important, la première canalisation peut être orientée angulairement par rapport à la seconde canalisation grâce au fait que le raccordement se comporte comme un assemblage à rotule. L'assemblage permet le rattrapage de la dispersion dû au montage des deux canalisations. Enfin, il y a une absence de soudure.  Such an arrangement has many disadvantages. The assembly of the upper oil return line 14 to the lower oil return line 20 is bulky. The number of pieces is important. High assembly time is required to assemble them. Finally, this solution poses problems of accessibility of the screws for disassembly, especially after-sales. The present invention relates to an arrangement for connecting a first pipe to a second pipe which overcomes these disadvantages. These objects are achieved by the fact that the first pipe has a collar in which is mounted an O-ring and in that the second pipe has a portion of enlarged diameter in which the flange and the O-ring of the first pipe is housed. Thanks to these characteristics the number of pieces is reduced. In particular, there is no screw or flange. The first pipe is in one component (flanges removal). The manufacture of parts is simpler and easier. Their cost is decreased. Assembly is fast and easy. According to a major advantage, the first pipe can be oriented angularly with respect to the second pipe thanks to the fact that the connection behaves like a ball joint. The assembly allows the catching up of the dispersion due to the assembly of the two pipes. Finally, there is an absence of welding.

De préférence, la partie de diamètre agrandi de la seconde canalisation est précédé d'une partie évasée. Dans un mode de réalisation préféré la première canalisation est un canal évacuation d'un circuit de lubrification d'un turbo compresseur et la seconde canalisation et une canalisation raccordée à un carter d'un moteur à combustion interne. D'autres caractéristiques et avantages de la présente invention apparaîtront encore à la lecture de la description qui suit d'un exemple de réalisation donné à titre illustratif en référence aux figures annexées. Sur ces figures : - la figure 1, déjà décrite, est une représentation schématique en perspective d'un circuit de retour d'huile d'un turbo compresseur conforme à l'art antérieur ; - la figure 2 est une vue en perspective à échelle agrandie d'une liaison d'une canalisation de retour d'huile supérieure à une canalisation de retour d'huile inférieure conforme à la présente invention. Sur la figure 2 on a désigné par la référence 32 une canalisation de retour d'huile supérieure de turbo compresseur et par la référence 34 une canalisation de retour d'huile inférieure. La canalisation 34 comporte une partie de diamètre agrandi 36 précédée d'une partie évasée 38. La canalisation de retour d'huile supérieure 32 est terminée par une collerette 40 dans laquelle est monté un joint torique 42. La canalisation de retour d'huile inférieure 34 peut être réalisée par hydroformage ou par déformation mécanique. Une patte de fixation 44 maintient l'extrémité de la canalisation de retour d'huile supérieure 32. La collerette 40 et le joint torique 42 sont introduits dans la partie de diamètre agrandi 36. Le joint torique réalise une étanchéité entre la canalisation de retour d'huile supérieure 32 et la canalisation de retour d'huile inférieure 34. D'autre part, comme on la signalé précédemment, les canalisations de retour d'huile supérieure et inférieure 32, 34 peuvent pivotées l'une par rapport à l'autre parce que la liaison entre elles se comporte comme une liaison à rotule. Ceci permet un rattrapage des dispersions dues au montage des deux canalisations.  Preferably, the enlarged diameter portion of the second pipe is preceded by a flared portion. In a preferred embodiment the first pipe is a drain channel of a lubrication circuit of a turbo compressor and the second pipe and a pipe connected to a casing of an internal combustion engine. Other features and advantages of the present invention will become apparent upon reading the following description of an exemplary embodiment given by way of illustration with reference to the appended figures. In these figures: FIG. 1, already described, is a diagrammatic representation in perspective of an oil return circuit of a turbo compressor according to the prior art; - Figure 2 is an enlarged perspective view of a connection of an upper oil return line to a lower oil return line according to the present invention. In Figure 2 there is designated by reference 32 a top turbo compressor oil return line and by reference 34 a lower oil return line. The pipe 34 has an enlarged diameter portion 36 preceded by a flared portion 38. The upper oil return pipe 32 is terminated by a flange 40 in which is mounted an O-ring 42. The lower oil return pipe 34 can be performed by hydroforming or by mechanical deformation. A fastening tab 44 holds the end of the upper oil return pipe 32. The flange 40 and the O-ring 42 are introduced into the enlarged diameter portion 36. The O-ring seals between the return pipe upper oil 32 and the lower oil return line 34. On the other hand, as previously mentioned, the upper and lower oil return lines 32, 34 can be rotated relative to one another. because the connection between them behaves like a ball joint. This allows a recovery of the dispersions due to the assembly of the two pipes.
