Abstract:
A load dependent braking pressure regulating device for railway vehicles, comprising an auxiliary reservoir (8) for storing pressurized air from a train pipe; a brake cylinder (10); and a control valve (9) operated by means of the pressure difference between the train pipe and the auxiliary reservoir (8) in such a manner that the pressurized air from the auxiliary reservoir (8) enters the brake cylinder (10) through the control valve (9) upon braking and that the pressurized air from the brake cylinder (10) is discharged to the atmosphere through the control valve (9) when the brake cylinder (10) is released, characterized in that a regulating valve (2), a sensor valve (4), a triggering board transmission mechanism (5) and a stop disc (6) are provided between the control valve (9) and the brake cylinder (10), a triggering head provided at the lower end of the stop disc (6) being directly opposite the center of a triggering board (28) of the triggering transmission mechanism (5), and the sensor valve (4) being connected through pipes with the control valve (9), the regulating valve (2), the brake cylinder (10) and a pressure reduction reservoir (7) respectively;said device being further characterized in that said sensor valve (4) and said stop disc (6) are installed on a support member (3), a round bar (12) extends from the bottom surface of the stop disc (6) into a vertical sleeve of said support member (3) and can move up and down in said sleeve.
