Abstract
A compressed air control apparatus for compressed air systems of motor vehicles includes a pressure controller (2), an air dryer (4) and a multi circuit protection valve (3). The pressure controller (2) controls the pressure in the compressed air control apparatus. The pressure controller (2) includes an outlet valve (8). The air dryer (4) dries the compressed air flowing through the compressed air control apparatus. The multi circuit protection valve (3) supplies a plurality of circuits (I, II, III, IV, V) with compressed air. The multi circuit protection valve (3) includes a plurality of overflow valves (23), at least one solenoid valve (32) and a regeneration conduit (36). Each of the overflow valves (23) is associated with one of the circuits (I, II, III, IV, or V). The at least one solenoid valve (32) arbitrarily operates the overflow valve (23), and it controls a regeneration phase of the air dryer (4) in which water is removed from the air dryer (4). The regeneration conduit (36) connects the solenoid valve (32) to the outlet valve (8) of the pressure controller (2).
