制御弁。[Scope of Claim for Utility Model Registration] An inertia valve that closes the flow path when a set deceleration is obtained and a differential pressure valve part are integrated into the fluid supply path to the actuator piston that sets the pressure reduction start point of the fluid pressure control mechanism. A load-responsive hydraulic pressure control valve is provided with a pressure increase sensing piston equipped with a pressure increase sensing piston, and an orifice is formed in a large diameter portion of the pressure increase sensing piston to generate a differential pressure according to a pressure increase rate of mask liquid pressure. A cylinder chamber is coaxially formed on the outside of the differential pressure valve part communicating with the liquid chamber on the outflow side of the orifice of the diameter part through an annular partition, and the cylinder chamber is composed of a ring member and a cup seal pressed against the cylinder chamber by a spring. A load-responsive hydraulic control valve characterized by having a dummy piston.
