Abstract

A fluid rotary machine, e.g. a hydraulic motor, has radial pistons (11) and a shaft (2) with an eccentric cam (7) having a rotational movement relative to the housing (1). The cam mounts a ring (8) on the exterior thereof and the pistons (11) abut against the exterior surface of the ring (8) with each piston (11) mounted for sliding movement in the interior of the cylinder (10). The ring (8) is associated with the distribution of the fluid of the machine to the pistons (11) and cylinders (10). Means are provided to immobilize the ring (8) against rotation relative to the housing (1) and subjugate the ring to an essentially circular translation movement relative to the rotational movement of the eccentric cam (7) on which the ring (8) is mounted, and is characterized by the fact that the means for maintaining the ring (8) in such a position comprises a plurality of elastic members (80a to 80e) connecting predetermined points (43) of the ring to anchor points (45) unassociated with the ring. These elastic members (80a to 80e) are sufficiently strong to oppose the tendency of the ring (8) to rotate with the cam (7), but on the other hand, have sufficient elasticity to be adaptable to different eccentricities of the cam (7) when the actual displacement of the machine is being changed. <IMAGE>
