  Perfectionnements relatifs aux raccords flexibles   @   pour organes tubulaires. 



    @   
La présente invention se rapporte aux raccords flexibles du genre utilisé pour joindre des tubes, des réservoirs ou dès parties de ceux-ci, ou d'autres organes tubulaires, et l'un de ses buts est de procurer un joint à enfoncer perfectionné. 



   Conformément à la caractéristique principale de la présente invention, il a été créé un raccord du genre mentionné ci-dessus, comportant au moins deux manchons à enfoncer, prolongeant une partie intermédiaire faisant office de tête, chacun de ces manchons étant muni à l'extérieur de dispositifs d'étanchéité déformables circonférentiels, ayant la forme de rainures annulaires en profil de dents de scie, disposés de manière à faciliter l'introduction du manchon dans le tuyau ou l'organe tubulaire, mais à offrir une résistance lorsqu'on le retire, et comportant au moins un canal le traversant et réunissant les dits manchons, lequel raccord est caractérisé par le 

 <Desc/Clms Page number 2> 

 fait que la tête comporte un évidement, dans l'une de ses faces dirigées vers les extrémités des organes tubulaires assemblés par le joint oundans les deux,

   pour recouvrir le bord de l'organe tubulaire qui s'y engage. 



     Eventuellement,   la partie intermédiaire faisant office de tête peut être munie sur une ou sur deux de ses faces d'un rebord annulaire, disposé de manière à entourer de façon étanche l'extérieur   d'un   organe tubulaire placé sur l'un des manchons ou sur les deux, et ce rebord peut avoir une forme telle   qu'il   puisse être retourné au-dessus de l'organe   tubulsire;   après que ce dernier a été mis en place sur le manchon da raccord. 



   Ce raccord peut avantageusement comporter au moins un tube flexible en faisant intégralement partie, se prolongeant à l'extérieur du raccord, pour constituer une continuation du dit canal traversant le raccord. De plus, le raccord peut être combiné à un tube rigide fixé à l'intérieur du canal ménagé dans le raccord, et traversant éventuellement celui-ci de part en part, auquel cas le dit canal est muni de préférence de dispositifs déformables permettant   d'étreindre   le tube.

 deux manchons, auquel cas chacun des deux manchons constitue un joint d'étanchéité intérieur, et chacun des deux rebords un joint extérieur. Les rebords 10 peuvent comporter des dispositifs d'étanchéité déformables, comme indiqué en 11, ou peuvent être rendus complémentaires de l'organe tubulaire. Un seul rebord 10 est prévu à la figure 5. Le rebord 10, d'autre part, au lieu d'être disposé demanière à être poussé sur l'organe tubulaire, peut être réalisé de manière à pouvoir être retourné au-dessus de celui-ci, après la mise en plac.e du manchon, comme l'indique la figure 6. 



   Plusieurs canaux peuvent être prévus à travers le raccord      Le raccord ne doit pas nécessairement être rectiligne; il peut être réalisé sans forme de coude. Plus de deux manchons peuvent être incorporés dans un seul raccord, qui peut avoir la forme d'un T. Dans ce cas, un second canal peut être prévu à travers deux seulement des manchons, en plus du canal 3, qui peut traverser les trois manchons, ou seulement deux d'entre eux. Des dispositifs faisant office de valve, par exemple un clapet de sureté, peuvent être incorporés dans les raccords. En variante, n'importe quel raccord peut être adapté pour recevoir des valves séparées, au lieu des dispositifs indicateurs de pression ou analogues, par exemple sur un bossage ou dans une cavité de la tête 2 ou d'une partie équivalente communiquant avec le canal 3.

  Improvements relating to flexible connectors @ for tubular components.



    @
The present invention relates to flexible couplings of the kind used to join tubes, reservoirs or parts thereof, or other tubular members, and one of its objects is to provide an improved push-in joint.



   In accordance with the main characteristic of the present invention, a fitting of the type mentioned above has been created, comprising at least two push-in sleeves, extending an intermediate part acting as a head, each of these sleeves being provided on the outside circumferential deformable sealing devices, in the form of annular grooves in the shape of saw teeth, arranged so as to facilitate the introduction of the sleeve into the pipe or the tubular member, but to offer resistance when it is removed , and comprising at least one channel passing through it and joining said sleeves, which connection is characterized by the

 <Desc / Clms Page number 2>

 that the head has a recess, in one of its faces directed towards the ends of the tubular members assembled by the joint oundans both,

   to cover the edge of the tubular member which engages therein.



     Optionally, the intermediate part acting as a head can be provided on one or on two of its faces with an annular rim, arranged so as to surround in a sealed manner the outside of a tubular member placed on one of the sleeves or on both, and this rim may have a shape such that it can be turned over above the tubulsire member; after the latter has been fitted to the coupling sleeve.



   This connector can advantageously comprise at least one flexible tube forming an integral part, extending outside the connector, to constitute a continuation of said channel passing through the connector. In addition, the connector can be combined with a rigid tube fixed inside the channel formed in the connector, and possibly passing through the latter right through, in which case said channel is preferably provided with deformable devices making it possible to hugging the tube.



   The accompanying figures represent, by way of example, several embodiments of the invention.



   Figure 1 is a sectional view of a single model of double sleeve connector.



   Figure 2 is a view of a detail of a modified fitting.



   Figure 3 is a detail view of another construction of the connector.



   Figure 4 shows a double sleeve fitting, with two flanges.



   Figure 5 shows a double sleeve fitting, with a single flange.



   Figure 6 shows a double-sleeved seal, with profiled head and reversible rim.

 <Desc / Clms Page number 3>

 two sleeves, in which case each of the two sleeves constitutes an inner seal, and each of the two flanges an outer seal. The flanges 10 may include deformable sealing devices, as indicated at 11, or may be made complementary to the tubular member. A single rim 10 is provided in FIG. 5. The rim 10, on the other hand, instead of being arranged to be pushed onto the tubular member, can be made so that it can be turned over on top of it. here, after the sleeve has been placed, as shown in Figure 6.



   Several channels can be provided through the connector. The connector does not necessarily have to be straight; it can be done without the elbow shape. More than two sleeves can be incorporated into a single fitting, which can be T-shaped. In this case, a second channel can be provided through only two of the sleeves, in addition to channel 3, which can pass through all three. sleeves, or just two of them. Devices acting as a valve, for example a safety valve, can be incorporated into the fittings. Alternatively, any fitting may be adapted to receive separate valves, instead of pressure indicating devices or the like, for example on a boss or in a cavity of the head 2 or an equivalent part communicating with the channel. 3.
