Claims

[Scope of utility model registration request]

(1) 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 differential pressure valve. In a load-responsive hydraulic control valve, a pressure increase sensing piston is provided, and an orifice is formed in a large diameter portion of the pressure increase sensing piston to generate a differential pressure according to a rate of increase in mask liquid pressure. A load-responsive hydraulic pressure control valve characterized in that one of the liquid chambers on both sides communicating through an orifice flow path, which is on the differential pressure valve side, communicates with a dummy piston pressed with a constant spring load. .

(2) The operating range of the dummy piston is 5 kg/cm2.
The load-responsive air pressure control valve according to claim 1, wherein the spring load is set to 90 kg/cm2.

(3) The amount of fluid required for the dummy piston is 0.4cc to 0.
．． 6 cc of the load responsive hydraulic pressure control valve according to claim 1 of the registered utility model claim.
