うにしたことを特徴とする液圧クラッチ用制御弁。 ′[Scope of Claim for Utility Model Registration] A spool and a push rod that connect the cylinder port to the pump port and the tank port alternately are slidably inserted into the valve hole of the valve body, and a spring that presses the spool toward the push rod is fitted. A piston is positioned between the spool and the push rod, and the piston enters from the large diameter part and the small diameter part, and the large diameter part of the piston is slidably fitted into a pressure receiving chamber formed at one end of the spool and communicating with the cylinder port. A pair of spring receiving seats with a spring interposed between the stepped part of the large diameter part and a stopper provided in the small diameter part of the piston are elastically fitted, and the pump hydraulic pressure is guided to the pressure receiving chamber. The push rod is in contact with the end of the small diameter portion and is located at the end of the stroke so as to substantially contact one of the spring receiving seats, and also to form a predetermined amount of clearance between the spool and the other spring receiving seat opposing thereto. A control valve for a hydraulic clutch characterized by: ′
