Abstract
A multiple-circuit brake system for motor vehicles in which a multiple-circuit braking value transducer is embodied partially electrically and partially as a pneumatic control valve and is intended for triggering pressure control valves, the wheel brake cylinders being disposed following these pressure control valves. One pressure-medium reservoir is associated with each pressure control valve, and the controlling energy for each of these pressure control valves is drawn from the pressure-medium reservoir associated with that valve. In the pneumatic brake circuit (I), a further pressure-medium reservoir is provided preceding the braking value transducer, as a result of which it is possible, with the aid of two-way check valves, to actuate the wheel brake cylinders with the pneumatic brake circuit (I) whenever the electrical brake circuits (II, III) have failed.
