ABSTRACT:
The hydraulic motor has a shaft rotatably mounted in a housing and mounting an eccentric to which is journaled an annular ring. A plurality of radial pistons are adapted for sliding movement within spherical members having cylindrical bores for receiving the radial pistons. Each of the spherical members is adapted for oscillating movement between an annular abutment and a spring-mounted annular ring-type valve seat.
The ring acts as a distributor sleeve or and as a conduit for fluid passing to and from the cylinders and a planar distributor.
The hydraulic motor can be used either as a pump or a motor at low or high speeds and under high pressures and is reversible.
