Claims

[Scope of utility model registration request]

A supply valve installed between the inlet and the outlet, and an exhaust valve installed between the outlet and the discharge port. The part includes a movable body that opens and closes the two valves, a load response device that changes the opening and closing positions of the two valves according to the load of the vehicle, an additional area portion provided at one end of the movable body, and a movable body that opens and closes the two valves. A load-responsive fluid pressure control valve comprising a valve device that introduces pressure to act on the additional area from the inlet side and closes when the inlet side pressure rises to a predetermined pressure, which acts on the additional area. A load-responsive fluid pressure control valve comprising a pressure regulating valve that opens and discharges water when the pressure exceeds the predetermined pressure.
