Abstract

L'invention concerne une machine hydraulique à pistons axiaux animés par un plateau oscillant, dont le bloc-cylindres 3 solidaire de l'arbre 4 se termine par une surface 32 percée d'un orifice de communication par cylindre et en contact constant, pendant le fonctionnement, avec un plateau 2 percé de deux orifices en arc de cercle, le mouvement rotatif relatif du bloc-cylindres et du plateau mettant alternativement chaque cylindre en communication avec les deux orifices en arc de cercle. Le dispositif améliore l'équilibrage des forces s'exerçant sur les divers éléments constitutifs de l'ensemble.The invention relates to a hydraulic machine with axial pistons driven by a swash plate, of which the cylinder block 3 integral with the shaft 4 ends in a surface 32 pierced with a communication orifice per cylinder and in constant contact, during the operation, with a plate 2 pierced with two circular arc openings, the relative rotary movement of the cylinder block and the plate alternately placing each cylinder in communication with the two circular arc openings. The device improves the balance of the forces exerted on the various constituent elements of the assembly.
