A constant displacement reversible hydraulic vane motor capable of being used in power hydraulic systems, hydrostatic transmissions, and the like. In existing motors with vanes mounted in the rotor and inlet and exhaust passages in the housing great sophistication in the grinding, assembly, and maintenance of the system is required. The simplified motor of this invention has a rotor (2) with a symmetric lobular outline which is engaged by vanes (22) to (29) mounted in a circular housing (1). The fluid to drive the motor enters through groove (10), orifices (12) and passages (20) and exhausts through passages (19), orifices (13) and groove (11) all in the rotor. Fluid supplied through the rotor enables the motor to operate at uniform speed without torque oscillation. |
