Abstract
An air spring system is disclosed. The air spring system has a compressor, which has a suction side and a delivery side, a pressure reservoir, a first valve device and a second valve device. Each valve device is connected between the compressor and the pressure reservoir. In order to provide the air spring system, which is of simple construction and can be produced economically, the first valve device and the second valve device are each embodied as 3/2-way valves.
