Claims (1)

[Claims for Utility Model Registration] When the set deceleration is obtained, the inertia valve is closed by the forward movement of the inertia valve body, and hydraulic pressure is contained in the liquid passage from this inertia valve to the actuator piston, and the contained hydraulic pressure is used to close the inertia valve. In a load-responsive hydraulic control valve that sets a spring point in the hydraulic control valve by spring compression of an actuator piston, a liquid inflow path is formed substantially parallel to the moving direction of the inertial valve body opposite to the forward movement side of the inertial valve body. A load-responsive hydraulic pressure control valve characterized in that a donut-shaped cap is disposed at the front of the inertial valve body to receive the liquid flow from the liquid inlet passage at a substantially right angle.
