ABSTRACT:
This invention achieves a complete dissipation of a residual pressure in a brake cylinder. The air brake system has a pressure control valve arranged between a brake valve and the brake cylinder. This pressure control valve has an outlet valve which controls the connection between an outlet chamber to which the brake cylinder is connected, and a venting space and has a control chamber. A connection between the control chamber and the venting space can be controlled by way of a control valve. There is furthermore a connecting conduit between the outlet chamber and the control chamber of the outlet valve. In the case of a braking operation, the control valve is switched briefly into its open position after the actuation of the brake valve ceases, allowing the residual pressure in the brake cylinder to be dissipated to the venting space via the connecting conduit. The method can be employed in commercial-vehicle air brake systems.
