ABSTRACT:
A compressed air control apparatus for compressed air systems of motor vehicles includes a pressure controller (10) for controlling the pressure, an air dryer (6) for drying the compressed air flowing through the compressed air control apparatus and a multi circuit protection valve (9) for supplying a plurality of circuits (I, II, III, IV, V) with compressed air. The multi circuit protection valve (9) includes at least one solenoid valve (35) including a deaerating connection (15) leading to the atmosphere and a plurality of overflow valves (18). Each of the overflow valves (18) is associated with one of the circuits (I, II, III, IV or V). The overflow valves (18) include a valve body (20), a flow chamber (23), a rear chamber (34), a first effective surface (22), a second effective surface (27), a third effective surface (33) and a spring (31) being located in the rear chamber (34). The valve body (20) separates the flow chamber (23) from the rear chamber (34). The valve body (20) has a first side facing the flow chamber (23) and a second side facing away from the flow chamber (23). The overflow valve (18) has an opening pressure being greater than its closing pressure to allow for limited backflow. The first effective surface is directly impinged with pressure by the solenoid valve. The third effective surface (33) is arranged either at the first side to be directly impinged with pressure or at the second side to be indirectly impinged with pressure.
