プ・モータの制御装置。A cylinder small-area chamber into which hydraulic oil is constantly introduced, and a cylinder large-area chamber into which hydraulic oil is introduced or communicated with a tank, which are provided at both ends of a servo piston connected to an inclination control unit of a hydraulic pump/motor, respectively; An inclined surface provided on a part of the servo piston and inclined with respect to the axis, a pilot piston located in opposition to this inclined surface at a position approximately perpendicular to the axis, and connected to the pilot piston via a spring. A spring that converts the stroke of the pilot piston based on the stroke of the servo piston into an inclination detection signal and detects it, a pilot spool that has this spring on one end and receives control pressure on the other end, and a pilot spool that controls the movement of the pilot spool. A control device for a hydraulic pump/motor comprising a pilot valve that introduces hydraulic oil into a cylinder large-area chamber or communicates the cylinder large-area chamber with a tank to operate a servo piston.
