Claims

[Scope of utility model registration request]

- The fluid supply path to the actuator piston that sets the pressure reduction start point of the fluid pressure control mechanism is equipped with an inertia valve that closes the flow path when the set deceleration is achieved, and a pressure increase sensing piston that is integrally equipped with a differential pressure valve. A load-responsive hydraulic pressure control valve that is arranged in series and has a structure in which the housing is divided into two at a portion between the inertia valve and the pressure increase sensing screw,
- The pressure increase sensing piston and the inertia valve are housed in the same case member and assembled between the two divided housings, and mask liquid pressure is supplied to the large diameter portion of the pressure increase sensing piston from the inflow side of the inertia valve to the case member. A load-responsive hydraulic pressure control valve characterized by forming a liquid supply path.
