Connecting assembly comprising a housing component (14), a stop ring (22) consisting of two half-rings (22A, 22B), and a length of shaft (12). Axial end stops (25) formed on the length of shaft prevent the ring from moving axially along the length of shaft. The connecting assembly comprises retaining means (34A, 34B) able, when the ring is placed in a mounted position around the length of shaft and held axially by the axial end stops, to prevent respective first ends of the half-rings from moving apart. In the mounted position, the ring prevents relative movement in an axial direction (X) of the length of shaft (12) with respect to the housing component (14). It is therefore interposed between the length of shaft (12) and the housing component (14) and is held radially against the length of shaft (12) by the housing component (14). The invention also relates to a method of mounting such a connecting assembly.

Distributeur (40) pour appareil hydraulique, comprenant un noyau (50) et une couronne de distribution (60) le noyau (50) présentant une pluralité de gorges internes (50A, 50B) le couronne de distribution (60) présentant une pluralité de gorges externes (60A, 60B) lesdites gorges internes (50A, 50B) et externes (60A, 60B) étant configurées pour être mises en communication fluidique et former des conduits de circulation de fluide, le noyau (50) comprenant une pluralité de segments d'étanchéité (52) configurés de manière à isoler lesdits conduits de circulation de fluide, le noyau (50) présentant une section externe décroissante depuis une extrémité distale (50D) vers une extrémité proximale (50P), le distributeur (40) étant caractérisé en ce que le couronne de distribution (60) comprend une butée (65) configurée de manière à limiter le déplacement du noyau (50) par rapport au couronne de distribution (60) selon une direction définie par l'axe (A).
摘要:
The present invention relates to a system comprising: a shaft having a distal end and a proximal end; a casing defining a housing in which a hydraulic device is rotatably mounted on the shaft; and a sealing element comprising a low pressure dynamic sealing means and a reinforced dynamic sealing means formed by a static seal tightly mounted on a friction pad, such as to isolate the dynamic sealing means from the rotating hydraulic device, said sealing element defining a discharge chamber between the dynamic sealing means and the reinforced dynamic sealing means, which discharge chamber is connected to a drain via a pipe arranged on the surface of the shaft, between the hydraulic device and the shaft, so as to discharge the fluid located in the discharge chamber, such that said discharge chamber is not subjected to the pressure in the casing of the hydraulic device.
