Compressed air supply system and pneumatic system

Abstract

The invention relates to a compressed air supply system (11, 21, 22, 23, 24, 25, 30, 41) for operating a pneumatic system (90, 901, 902), in particular a pneumatic suspension of a vehicle, comprising: a compressed air supply (1); a first pneumatic connection between the compressed air supply (1) and the pneumatic system (90, 901, 902), comprising an air desiccator (61), throttle means (62) and at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163); a second pneumatic connection which is pneumatically connected to the first pneumatic connection and to a ventilation connection (3) for connecting to the surroundings and which has at least one controllable ventilation valve (73, 73′, 73″, 73′″, 73IV, 173). According to the invention, said at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163) and the throttle means (62) are aligned in the first pneumatic connection in such a manner that the at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163) can be switched in an open state, into the flow through mode, and in the closed state, into a separation mode. In the closed state, the first pneumatic connection is completely closed in both directions and said at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163) can be switched, in the flow through mode, between a first control state, associated with a closed state, and a second control state which is associated with an open state.
