Abstract

L'invention concerne une machine rotative hydraulique conçue de manière à réduire la résistance au glissement d'un piston alternatif et à supprimer la réduction de rendement volumique correspondant à la quantité de fuite d'huile hydraulique. Une pompe à piston (1) est munie d'un arbre rotatif (11), d'un bloc de cylindres (12), d'une tête de piston (13), d'une tige de piston (14), d'un élément de retenue (15), d'un plateau oscillant (16) et d'un mécanisme de régulation d'inclinaison (17). Lorsque le mécanisme de régulation d'inclinaison (17) fait basculer le plateau oscillant (16), le débit de la pompe à piston (1) est modifié de manière variable. L'élément de retenue (15) qui tourne conjointement avec la tête de piston (13) et la tige de piston (14) est soutenu par un manchon de retenue (11A) prévue sur l'arbre rotatif (11). La section sphérique (15A) de l'élément de retenue (15) et la section sphérique (11B) du manchon de retenue (11A) ont des formes sphériques de même courbure. Pendant la régulation de l'inclinaison, l'élément de retenue (15) bascule alors que la section sphérique (11B) de l'élément de retenue est en contact glissant avec le manchon de retenue (11A).
