An improved prosthetic device having a plurality of independently movable members that operate at peak efficiency for a majority of the time that it is in the on state, thereby extending battery life, includes at least two members that are independently movable, a fluid actuator associated with each of the independently movable members for effecting movement, a fluid pump or compressor having a fluid inlet and a compressed or pressurized fluid outlet, an electrical motor coupled to the pump or compressor, a fluid conveying conduit between the pump or compressor outlet and the actuator, a fluid reservoir in communication with the conduit between the pump or compressor outlet and the actuator, and at least one valve associated with each of the independently movable members.
