Abstract
A pressure medium actuated braking system comprises at least first and second braking circuits, and a multi-circuit braking power imparting device, such as a motorcar brake valve. The first braking circuit assigned to, e.g., the rear axle, has a first pressure medium storage container, at least one braking cylinder, and a first control valve system which connects the braking cylinder to the first pressure medium storage container or to a pressure medium sink (atmosphere) depending on a first control signal produced by the motorcar brake valve. The second braking circuit, assigned to, e.g., the front axle, has a second pressure medium storage container, first and second braking cylinders, and a second control valve system which connects the first and second braking cylinders to the second pressure medium storage container or to a pressure medium sink depending on a second control signal generated by the motorcar brake valve. The second braking circuit also includes an additional control valve system disposed between a pressure medium output of the second control valve system and one of the brake cylinders of the second braking circuit. The additional control valve system can connect this braking cylinder to a third pressure medium storage container which is independent of the second pressure medium storage container in dependence on the first control signal.
