ンシングバルブ。A differential piston is slidably mounted within the valve body so that the pressure output from the brake valve is applied to the small diameter end, and the pressure supplied to the relay valve is applied to the large diameter end, and the differential piston is slidably mounted together with the piston. A valve that moves to open and close the core passage from the brake valve to the relay valve, a spring that presses the piston toward the large diameter end and holds the valve open, and a spring that moves as the excitation current increases. an electromagnetic actuator that further reduces the pressing force caused by the tension of the frame; and a load detector that reduces the excitation current supplied to the electromagnetic actuator as the load detected based on the amount of relative displacement between the frame and the axle increases. A load sensing valve for air brakes.
