HYDRAULIC MOTOR Russian patent published in 1996 - IPC

FIELD: mechanical engineering; hydraulic drives for transport facilities, such as self-propelled trolleys and motor scooters; hydraulic systems of mini transport facilities. SUBSTANCE: inlet and outlet passages are located in hydraulic motor tangentially relative to cylindrical working chamber. Bearing shoulders fitted in separating plates of rotor received by end slots of guide bushes make it possible to rotate separating plates in bearings providing for definite clearance between cylindrical surface of stator and longitudinal end of separating plates, thus reducing friction in motion.
