Abstract

La présente invention concerne une machine hydraulique comprenant un bloc cylindres (30) comportant des cylindres (32) logeant des pistons (50), un distributeur (60) comprenant des canaux (61, 64) qui communiquent avec les cylindres (32) et comprenant deux éléments complémentaires (62, 66) concentriques susceptibles de coulissement axial relatif et des moyens d'étanchéité (70, 72, 74 ; 100) disposés entre les deux éléments complémentaires concentriques (62, 66) dans lequel les moyens d'étanchéité (70, 72, 74) comprennent au moins deux joints annulaires continus comprenant chacun une base adaptée pour être placée dans une rainure respective formée dans l'un des éléments complémentaires (62, 66) de distributeur et une ailette en forme de lèvre adaptée pour reposer élastiquement contre une surface de l'autre élément complémentaire (66, 62) de distributeur placée en regard et assurer une étanchéité à ce niveau, les joints annulaires étant réalisés en un matériau permettant une déformation élastique du joint autorisant l'engagement de la base dans la rainure respectivement associée.The present invention relates to a hydraulic machine comprising a cylinder block (30) comprising cylinders (32) housing pistons (50), a distributor (60) comprising channels (61, 64) which communicate with the cylinders (32) and comprising two complementary concentric elements (62, 66) capable of relative axial sliding and sealing means (70, 72, 74; 100) arranged between the two complementary concentric elements (62, 66) in which the sealing means (70 , 72, 74) comprise at least two continuous annular seals each comprising a base adapted to be placed in a respective groove formed in one of the complementary distributor members (62, 66) and a lip-shaped fin adapted to resiliently rest against a surface of the other complementary element (66, 62) of the dispenser placed opposite and ensure a seal at this level, the annular seals being made of a material allowing deformation elastic seal allowing the base to engage in the respective associated groove.
