Abstract
A hydraulic motor has a housing with an inner toothed ring, and an outer toothed wheel eccentrically mounted within the ring, with pressure pocket space between the teeth of the ring and the wheel. The wheel is eccentrically rotatably and orbitally mounted within the ring. A rotary slide valve is mounted within the wheel. A valve plate with an open center is adjacent the wheel. A rotary slide valve is positioned within the open center of the valve plate. Fluid under pressure in passageways is provided to a front group of pressure pocket spaces to cause the wheel to rotate. An output shaft is operatively connected to the wheel.
