A rotary fluid energy converter which can be used either as a hydraulic pump or as a motor, can recover energy with high efficiency. The converter has a spring for biasing a pintle, which supports a torque ring, in one direction, and a hydraulic actuator for moving the pintle in the opposite direction against the action of the spring. A high pressure fluid used in the converter is introduced into the actuator via a pressure-compensating valve to maintain the pressure of this fluid at the pressure set for the valve at all times.
