Description

"Ensemble hydraulique à assemblage comportant une étanchéité perfectionnée" L'invention concerne un ensemble hydraulique. L'invention concerne plus particulièrement un ensemble de conduit de fluide comportant : - un premier organe, comportant un premier alésage d'un premier axe déterminé, débouchant dans une première face de fixation dudit premier organe, - un second organe, comportant un second alésage d'un second axe déterminé formant un angle d'inclinaison déterminé avec le premier axe, débouchant dans une seconde face de fixation dudit second organe, lesdits organes étant assemblés l'un à l'autre par l'intermédiaire de leur première et seconde faces de fixation, les premier et 15 second alésages étant agencés sensiblement en regard l'un avec l'autre. On connait de nombreux exemples d'ensembles hydrauliques de ce type. Dans de tels ensembles, l'étanchéité entre les organes est 20 conventionnellement effectuée à la jonction des première et deuxième faces de fixation, par exemple au moyen d'un joint qui circonvient les premier et second alésages. Selon la mobilité qui est prévue entre les premier et second organes hydrauliques le joint peut être de différents types, tel qu'un joint plan de type joint 25 papier ou encore un joint torique. La qualité de l'étanchéité est déterminée par la planéité des première et deuxième faces de fixation ainsi que par leur serrage l'une contre l'autre. De ce fait, et notamment dans le cas de premier et second organes hydrauliques traversés par un fluide soumis à une 30 pression élevée, l'étanchéité peut se révéler difficile à obtenir, ou tout du moins très couteuse. L'invention remédie à cet inconvénient en proposant une nouvelle conception d'un ensemble de conduit de fluide dont l'étanchéité est réalisée de manière interne entre les premier et second alésages. Selon cette conception, l'étanchéité proposée permet également de s'affranchir de l'angle d'inclinaison entre les premier et second alésages. Dans ce but, l'invention propose un ensemble de conduit de fluide du type décrit précédemment, caractérisé en ce qu'il comporte un élément tubulaire intermédiaire d'étanchéité qui est reçu dans les premier et second alésages, qui comporte des extrémités opposées reçues respectivement de manière étanche dans lesdits premier et second alésages, et qui comporte des moyens d'adaptation à l'angle d'inclinaison déterminé. Selon d'autres caractéristiques de l'invention : - l'élément tubulaire est rigide et les moyens d'adaptation comportent au moins une articulation, - chacune des extrémités opposées de l'élément tubulaire rigide comporte une articulation qui est interposée entre ladite extrémité et un tronçon correspondant du premier/second alésage dans laquelle elle est reçue, - chacune des extrémités est conformée en une tête de rotule qui est reçue avec un jeu fonctionnel de rotation dans le tronçon correspondant du premier/second alésage et qui comporte une gorge recevant un joint torique d'étanchéité avec ledit premier second alésage, - l'élément tubulaire rigide comporte entre ses extrémités un tronçon cylindrique de révolution, - chaque joint torique est agencé dans un plan transversal à l'axe du tronçon cylindrique de révolution, - chaque joint est compressible dans la gorge associée 30 selon une hauteur de compression associée à une pression déterminée d'un fluide circulant dans les premier et second organes hydrauliques, - chaque premier/second alésage du premier/second organe comporte au moins un premier/second tronçon d'articulation qui reçoit une extrémité associée conformée en tête de rotule de l'élément tubulaire, et un premier/second tronçon coaxial de débattement, d'un diamètre supérieur au premier/ second tronçon d'articulation, qui est interposé entre ledit premier/second tronçon d'articulation et la première/seconde face de fixation du premier/second organe, - chaque premier/second alésage du premier/second organe hydraulique comporte au moins un premier/second tronçon d'alimentation, qui est agencé coaxialement au premier/second tronçon d'articulation à l'opposé du premier/second tronçon coaxial de débattement, et qui présente un diamètre correspondant à un diamètre intérieur de l'élément tubulaire.The invention relates to a hydraulic assembly. The invention more particularly relates to a fluid conduit assembly comprising: - a first member, comprising a first bore of a first determined axis, opening into a first fixing face of said first member, - a second member, comprising a second bore a second determined axis forming an angle of inclination determined with the first axis, opening into a second attachment face of said second member, said members being assembled to one another via their first and second faces the first and second bores being arranged substantially facing each other. Many examples of hydraulic assemblies of this type are known. In such assemblies, the sealing between the members is conventionally performed at the junction of the first and second attachment faces, for example by means of a seal which circumscribes the first and second bores. Depending on the mobility that is provided between the first and second hydraulic members the seal may be of different types, such as a planar gasket or an O-ring. The quality of the seal is determined by the flatness of the first and second fixing faces as well as by their tightening against each other. Therefore, and particularly in the case of first and second hydraulic members traversed by a fluid subjected to high pressure, the seal may be difficult to obtain, or at least very expensive. The invention overcomes this disadvantage by proposing a new design of a fluid conduit assembly whose sealing is performed internally between the first and second bores. According to this design, the proposed seal also eliminates the angle of inclination between the first and second bores. For this purpose, the invention proposes a fluid conduit assembly of the type described above, characterized in that it comprises a tubular intermediate sealing element which is received in the first and second bores, which has opposite ends received respectively in a sealed manner in said first and second bores, and which comprises means of adaptation to the determined angle of inclination. According to other features of the invention: the tubular element is rigid and the adaptation means comprise at least one articulation, each of the opposite ends of the rigid tubular element comprises a hinge which is interposed between said end and a corresponding section of the first / second bore in which it is received, - each of the ends is shaped into a ball head which is received with a functional clearance of rotation in the corresponding portion of the first / second bore and which comprises a groove receiving a O-ring seal with said first second bore, - the rigid tubular element comprises between its ends a cylindrical section of revolution, - each O-ring is arranged in a plane transverse to the axis of the cylindrical section of revolution, - each seal is compressible in the associated groove 30 according to a compression height associated with a determined pressure of a fluid flowing in the first and second hydraulic members, - each first / second bore of the first / second member comprises at least a first / second hinge section which receives an associated end formed at the ball head of the tubular element, and a first / second coaxial portion of deflection, of a diameter greater than the first / second articulation section, which is interposed between said first / second articulation section and the first / second attachment face of the first / second member; each first / second bore of the first / second hydraulic member comprises at least a first / second feed section, which is arranged coaxially with the first / second hinge section opposite the first / second coaxial section of displacement, and which has a diameter corresponding to an inner diameter of the tubular element.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera au dessin annexé dans lequel la figure unique est une vue en coupe d'un ensemble hydraulique selon l'invention.Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the attached drawing in which the single figure is a sectional view of a hydraulic assembly according to the invention. .

Dans la description qui va suivre, des chiffres de référence identiques désignent des pièces identiques ou ayant des fonctions similaires. On a représenté à la figure unique un ensemble hydraulique 10 réalisé conformément à l'invention.In the following description, like reference numerals designate like parts or having similar functions. There is shown in the single figure a hydraulic assembly 10 made according to the invention.

De manière connue, l'ensemble 10 comporte un premier organe hydraulique 12, comportant un premier alésage 14 d'un premier axe « A » déterminé, qui débouche dans une première face de fixation 16 dudit premier organe 12. L'ensemble 10 comporte un second organe hydraulique 18, comportant un second alésage 20 d'un second axe « B » déterminé formant un angle « a » d'inclinaison déterminé avec le premier axe « A », qui débouche dans une seconde face 22 de fixation dudit second organe 18.In known manner, the assembly 10 comprises a first hydraulic member 12, having a first bore 14 of a first axis "A" determined, which opens into a first attachment face 16 of said first member 12. The assembly 10 comprises a second hydraulic member 18, comprising a second bore 20 of a second axis "B" determined forming an angle "a" of inclination determined with the first axis "A", which opens into a second face 22 for fixing said second member 18 .

Les premier et second organes 12, 18 sont assemblés l'un à l'autre par l'intermédiaire de leur première et seconde faces de fixation 16, 22. Les premier et second alésages 14, 20 sont agencés sensiblement en regard l'un avec l'autre.The first and second members 12, 18 are connected to each other via their first and second attachment faces 16, 22. The first and second bores 14, 20 are arranged substantially opposite each other. the other.

Dans un tel ensemble hydraulique 10, l'étanchéité entre les organes 12, 18 est conventionnellement effectuée à la jonction des première et deuxième faces 16, 22 de fixation, par exemple au moyen d'un joint qui circonvient les premier et second alésages 14, 20. Selon la mobilité qui est prévue entre les premier et second organes hydrauliques 12, 18, le joint peut être de différents types. Il peut s'agir d'un joint statique, mis en place préalablement à l'assemblage des organes 12, 18, tel qu'un joint plan de type joint papier ou élastomère.In such a hydraulic assembly 10, the seal between the members 12, 18 is conventionally made at the junction of the first and second fixing faces 16, 22, for example by means of a seal which circumscribes the first and second bores 14, 20. Depending on the mobility that is provided between the first and second hydraulic members 12, 18, the seal may be of different types. It may be a gasket, set up prior to the assembly of members 12, 18, such as a flat gasket type seal paper or elastomer.

Il peut aussi s'agir d'un joint permettant une certaine mobilité relative entre les premier et second organes 12, 18, tel qu'un joint torique reçu dans une gorge complémentaire formée dans une des faces 16, 22 de fixation. En tout état de cause, pour une pression déterminée de fluide hydraulique traversant les premier et second organes 12, 18, la qualité de l'étanchéité est déterminée d'une part la planéité des première et deuxième faces 16, 22 de fixation et d'autre part par le serrage desdites faces l'une contre l'autre qui détermine l'écrasement du joint.It may also be a seal allowing a certain relative mobility between the first and second members 12, 18, such as an O-ring received in a complementary groove formed in one of the faces 16, 22 of attachment. In any case, for a given pressure of hydraulic fluid passing through the first and second members 12, 18, the quality of the seal is determined on the one hand the flatness of the first and second faces 16, 22 of attachment and of secondly by clamping said faces against each other which determines the crushing of the seal.

De ce fait, et notamment dans le cas de premier et second organes 12, 18 qui sont traversés par un fluide soumis à une pression élevée par exemple une huile hydraulique de transmission de puissance, l'étanchéité peut se révéler difficile à obtenir, ou tout du moins très couteuse.Therefore, and in particular in the case of first and second members 12, 18 which are traversed by a fluid subjected to a high pressure, for example a hydraulic power transmission oil, sealing may be difficult to obtain, or any at least very expensive.

Pour remédier à cet inconvénient, l'invention propose un ensemble de conduit de fluide dans lequel l'étanchéité est réalisée dans les premier et second alésages 14, 20.To remedy this drawback, the invention proposes a fluid conduit assembly in which the seal is made in the first and second bores 14, 20.

Dans ce but, l'invention propose un ensemble 10 du type décrit précédemment, caractérisé en ce qu'il comporte un élément tubulaire intermédiaire d'étanchéité 24 qui est reçu dans les premier et second alésages 14, 20, qui comporte des extrémités opposées reçues respectivement de manière étanche dans lesdits premier et second alésages 14, 20 et qui comporte des moyens d'adaptation 26 à l'angle « a » d'inclinaison déterminé. Plusieurs possibilités peuvent être envisagées pour former les moyens d'adaptation 26 à l'angle « a » d'inclinaison déterminé. Par exemple l'élément tubulaire intermédiaire d'étanchéité pourrait être flexible. Toutefois, dans le mode de réalisation préféré de l'invention, l'élément tubulaire 24 est rigide et en ce que les moyens d'adaptation 26 comportent au moins une articulation.For this purpose, the invention proposes an assembly 10 of the type described above, characterized in that it comprises an intermediate tubular sealing element 24 which is received in the first and second bores 14, 20, which has opposite ends received respectively in said first and second bores 14, 20 and which comprises means 26 for matching the angle of inclination "a" determined. Several possibilities can be envisaged for forming the matching means 26 at the determined angle "a" of inclination. For example the intermediate tubular sealing element could be flexible. However, in the preferred embodiment of the invention, the tubular element 24 is rigid and in that the adaptation means 26 comprise at least one articulation.

Les moyens d'adaptation 26 pourraient comporter une articulation unique agencée dans une partie intermédiaire de l'élément tubulaire 24. Toutefois, de préférence, chacune des extrémités opposées 28, 30 de l'élément 24 tubulaire rigide comporte une articulation 26 qui est interposée entre ladite extrémité 28, 30 et un tronçon 32, 34 correspondant du premier/second alésage 14, 20 dans laquelle elle est reçue. Plus particulièrement, chacune des extrémités 28, 30 est conformée en une tête de rotule qui est reçue avec un jeu fonctionnel de rotation dans le tronçon correspondant 32, 34 du premier/second alésage 14, 20 et qui comporte une gorge associée 36, 38 recevant un joint torique 40, 42 d'étanchéité avec ledit premier second alésage 14, 20. La tête de rotule peut prendre toute forme apte à assurer une rotation dans le tronçon correspondant 32, 34 du premier/second alésage 14, 20. Elle peut donc être sphérique, ovoïde, ou ellipsoïde de révolution.The adaptation means 26 could comprise a single articulation arranged in an intermediate part of the tubular element 24. However, preferably, each of the opposite ends 28, 30 of the rigid tubular element 24 comprises a hinge 26 which is interposed between said end 28, 30 and a corresponding section 32, 34 of the first / second bore 14, 20 in which it is received. More particularly, each of the ends 28, 30 is shaped into a ball head which is received with a functional clearance of rotation in the corresponding section 32, 34 of the first / second bore 14, 20 and which has an associated groove 36, 38 receiving an o-ring 40, 42 sealing with said first second bore 14, 20. The ball head may take any form capable of ensuring a rotation in the corresponding section 32, 34 of the first / second bore 14, 20. It can therefore be spherical, ovoid, or ellipsoid of revolution.

Dans le mode de réalisation préféré de l'invention, l'élément tubulaire rigide 24 comporte entre ses extrémités 28, 30 un tronçon cylindrique 44 de révolution d'axe général « C ». Sur la figure unique, l'axe « C » du tronçon 44 est coaxial à l'axe « A » premier alésage 14. Toutefois cette configuration n'est pas limitative de l'invention et dépend de l'axe « A » d'inclinaison. De préférence. chaque joint torique 40, 42 est agencé dans un plan transversal à l'axe « C » du tronçon 44 cylindrique de révolution. Chaque joint 40, 42 est adapté à la pression du fluide hydraulique traversant les premier et second organes 12, 18. Ainsi, chaque joint 40, 42 est compressible dans la gorge associée 36, 38 selon une hauteur « X » de compression associée à une pression déterminée d'un fluide circulant dans les premier et second organes 12, 18. Pour permettre l'inclinaison l'élément tubulaire rigide 24, chaque premier/second alésage 14, 20 du premier/second organe hydraulique 18, 20 comporte au moins un premier/second tronçon d'articulation 32, 34 qui reçoit l'extrémité associée 28, 30 conformée en tête de rotule de l'élément tubulaire, et un premier/second tronçon coaxial 48, 50 de débattement, d'un diamètre supérieur au premier/second tronçon d'articulation 32, 34, qui est interposé entre ledit premier/second tronçon d'articulation 32, 34 et la première/seconde face de fixation 16, 22 du premier/second organe hydraulique 12, 18. Ce tronçon 48, 50 de débattement permet la mobilité du tronçon intermédiaire 44 de l'élément rigide tubulaire 24. Enfin, chaque premier/second alésage 14, 20 du premier/second organe 12, 18 comporte au moins un premier/second tronçon d'alimentation 52, 54, qui est agencé coaxialement au premier/second tronçon d'articulation 32, 34 à l'opposé du premier/second tronçon coaxial 48, 50 de débattement, et qui présente un diamètre correspondant à un diamètre intérieur « d » de l'élément tubulaire, pour permettre l'alimentation de l'élément intermédiaire 24. L'invention permet donc d'assurer de manière optimale la 5 liaison de deux organes hydrauliques ou aérauliques 12, 18 d'axes non coaxiaux.In the preferred embodiment of the invention, the rigid tubular element 24 comprises between its ends 28, 30 a cylindrical section 44 of revolution of general axis "C". In the single figure, the axis "C" of the section 44 is coaxial with the axis "A" first bore 14. However, this configuration is not limiting of the invention and depends on the axis "A" of tilt. Preferably. each O-ring 40, 42 is arranged in a plane transverse to the "C" axis of the cylindrical section of revolution. Each seal 40, 42 is adapted to the pressure of the hydraulic fluid passing through the first and second members 12, 18. Thus, each seal 40, 42 is compressible in the associated groove 36, 38 at a height "X" of compression associated with a determined pressure of a fluid flowing in the first and second members 12, 18. To allow the inclination of the rigid tubular element 24, each first / second bore 14, 20 of the first / second hydraulic member 18, 20 comprises at least one first / second articulation section 32, 34 which receives the associated end 28, 30 shaped as the ball head of the tubular element, and a first / second coaxial section 48, 50 of displacement, of a diameter greater than the first second articulation section 32, 34, which is interposed between said first / second articulation section 32, 34 and the first / second attachment face 16, 22 of the first / second hydraulic member 12, 18. This section 48, 50 of travel allows the mobility of the intermediate portion 44 of the rigid tubular element 24. Finally, each first / second bore 14, 20 of the first / second member 12, 18 comprises at least a first / second supply section 52, 54, which is arranged coaxially at the first / second articulation section 32, 34 opposite the first / second coaxial section 48, 50 of displacement, and which has a diameter corresponding to an internal diameter "d" of the tubular element, to allow the The invention thus optimally ensures the connection of two hydraulic or aeraulic members 12, 18 of non-coaxial axes.
