Abstract

A compressed air supply device for operating a pneumatic system, such as a vehicle pneumatic suspension system, comprises a compressed air supply, a first pneumatic connection between the compressed air supply and the pneumatic system, the first pneumatic connection having an air desiccator, a throttle device, and at least one controllable isolating valve, and a second pneumatic connection pneumatically connected to the first pneumatic connection and to a vent connection leading to the surroundings, the second pneumatic connection having at least one controllable vent valve. According to one embodiment, the controllable isolating valve and the throttle device are arranged in series in the first pneumatic connection such that the controllable isolating valve can be switched into an open state when in a through-flow mode, and into a closed state when in an isolating mode.
