Abstract:
1. A tire inflation system, comprising a compressed-air generating system, a compressed-air reservoir, a valve block and pneumatically driven wheel valves in the wheels of a motor vehicle, with electrically operated pilot control valves which are fixed to the vehicle each driving at least one wheel valve, the compressed-air generating system has a first compressor and a second compressor, the first compressor makes compressed air available to a first compressed-air system designed to receive compressed air at a first pressure level, and the second compressor makes compressed air available to a second compressed-air system designed to receive compressed air at a second-pressure level higher than the first pressure level, wherein the wheel valves are arranged in the first compressed-air system, and the pilot control valves are arranged in the second compressed-air system, and the second compressed-air system also supplies, in addition to the tire inflation system, air to a plurality of pneumatic suspension bellows for pneumatic wheel suspension or level control.
