ABSTRACT:
The hydraulic actuator (35) utilizes the centrifugal head developed in its pressure chambers (52,54) when the housing (44) rotates as a source of pressure. As actuator (35) rotates fluid exits outlet port (56) and passs through a servovalve (64) into chamber (54) to move vane (49) relative to the actuator (35). To move vane (49) in the other direction, fluid exits outlet port (58) and passes through the valve into chamber (52). This self-powered actuator has utility in systems requiring relative angular positioning between a pair of rotating elements such as a pair of voltage regulator rotors in a dual permanent magnet generator.
