Method and device for preparation of compressed air in motor vehicles

In a method and a device for compressed air preparation in motor vehicles, ambient air is drawn in and compressed by a compressor (2), dried in a downstream air dryer (4, 4′) and delivered to compressed air consumers (storage tanks 14, 16). The air dryer (4, 4′) is regenerated with system air stored...

Zusammenfassung:	In a method and a device for compressed air preparation in motor vehicles, ambient air is drawn in and compressed by a compressor (2), dried in a downstream air dryer (4, 4′) and delivered to compressed air consumers (storage tanks 14, 16). The air dryer (4, 4′) is regenerated with system air stored in a regeneration reservoir (30, 30′), passed via the air dryer (4, 4′) and vented via an associated vent valve (22). In predetermined operating states, a switch is made between a delivery phase and a regeneration phase via an electrically controlled governor (36, 36′). The delivery phase of the compressor takes place at least when compressed air consumption is high, and the regeneration phase takes place in the stationary mode at the idling speed of the drive motor, to keep the delivery phases short and to have sufficient time available for regeneration.
