ABSTRACT:
An air brake system for a railway vehicle has a brake control valve connected to a main air line which is maintained at a certain pressure when the brakes are released. Connected to the brake control valve is an air reservoir and a brake cylinder which is connected through suitable linkage to operate a friction brake. A valve device is provided which is actuated in response to the operating state of the friction brake and pressure in the main air line and includes a venting valve connected to the main air line so that the venting valve is opened during a simultaneous occurrence of the brake being in the braking state and the regular pressure level is maintained in the air line. Under other conditions the venting valve is closed.
