Abstract:
A pneumatic system for a motor vehicle, comprising:a compressor unit; a storage unit; on-off valves for supplying compressed air from said compressor unit to individual pneumatic springs of individual vehicle wheels; a main vent line provided between the compressor unit and the on-off valves, said vent line opening up into the atmosphere; a locking valve operatively arranged to close the vent line; and a separately lockable high-pressure vent line connected in parallel to the vent line, wherein a clear through-flow cross section of the separately lockable high-pressure vent line is smaller than a clear through-flow cross section of the main vent line, wherein an air mass flow emerging into the atmosphere via the vent line when opened is limited with respect to its unlimited state during a certain time interval.
