圧力制御弁。[Claim for Utility Model Registration] The valve chamber is equipped with a valve chamber into which handled fluid flows, and a discharge chamber that communicates with this valve chamber through a port. In a pressure control valve that houses a valve body that reciprocates in a predetermined direction to open and close, an inlet for introducing external fluid is provided in the discharge chamber at a position facing the valve body, and a connection between the inlet and the valve is provided. A bag-shaped expandable body that expands and contracts along the reciprocating direction of the valve body due to the pressure of external fluid is arranged between the valve body and the valve body.
A pressure control valve characterized in that the opening of the expandable body is fluid-tightly joined to the inlet, and the bottom is brought into contact with the valve body.
