Abstract
A pressure medium actuated braking system comprises a first (rear axle) braking circuit, a second (front axle) braking circuit, and a multi-circuit braking power imparting device, such as a motorcar brake valve. The motorcar brake valve produces first and second control signals for the first and second braking circuits. The first braking circuit has a first pressure medium storage container assigned to it, 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 the first control signal. The second braking circuit has a second pressure medium storage container, first and second braking cylinders, and a second control valve system. The second control valve system comprises first and second control valves assigned to the first and second brake cylinders respectively of the second braking circuit. The first control valve connects the first braking cylinder to the second pressure medium storage container, to a third pressure medium storage container, or to a pressure medium sink, depending on the first and second control signals. The second control valve connects the second braking cylinder of the second braking circuit to the second pressure medium storage container or to a pressure medium sink depending on the second control signal produced by the motorcar brake valve for the second braking circuit.
