Claims

[Claims for Utility Model Registration] A pair of valve pistons that control the brake fluid pressure of two hydraulic circuits that independently supply brake fluid pressure to the left and right rear brakes of a vehicle are installed in a single housing, mutually. a valve portion disposed parallel to the housing with one end protruding outside the housing; An equalizer that evenly distributes and transmits a biasing force in the direction of pushing the valve piston into the housing to a protruding end thereof, a cover that covers the equalizer and is fixed to the housing, and a cover that extends through the cover. , a load-sensitive type including a load transmission member whose inner end is engaged with the equalizer, and a rear wheel load sensing mechanism that applies a load to the outer end of the load transmission member in accordance with the rear wheel load of the vehicle. In the hydraulic control valve, the equalizer and the load transmission member are arranged so that at least when the pair of valve pistons are both in non-operating positions, the equalizer is located on the valve piston side relative to the load transmission member. When the pair of valve pistons are both in the non-operating position, the load transmitting member or a member fixed thereto comes into contact with the cover, and when The rear independent dual system is characterized in that the load transmission member is movable toward the valve piston, so that the biasing force is not transmitted to the valve piston in a non-operating state. Hydraulic pressure control valve for braking equipment.
