重応答型液圧制御弁。[Claim for Utility Model Registration] The master hydraulic pressure at that time is sealed in the actuator piston by actuation of an inertia valve that senses the set deceleration, and a spring load corresponding to the sealed hydraulic pressure is applied to the hydraulic pressure control mechanism. In a load-responsive hydraulic control valve that sets a split point, a control piston that is biased in one direction by a spring and can freely slide is provided in the middle of the hydraulic pressure supply passage from the inertia valve to the actuator piston. The control piston introduces a first master hydraulic pressure via the inertia valve into the spring contacting side liquid chamber, and supplies a second master hydraulic pressure introduced from the outer circumference to the actuator piston. It has an internal flow path, and closes the internal flow path when it moves in response to an increase in the second master hydraulic pressure due to the interruption of the first master hydraulic pressure due to the operation of the inertia valve. A load-responsive hydraulic pressure control valve, characterized in that a poppet valve mechanism is provided on the actuator piston side to confine hydraulic pressure, and a differential pressure valve is further provided in a passage for supplying master hydraulic pressure to the inertia valve.
