A pneumatic spring arrangement with integrated valve control for controlling the level position of a vehicle or a driver's cab is described, comprising a rolling tube and a cover and a pneumatic spring bellows which, together with the rolling tube and the cover, delimits a pressure chamber with compressed air, a control valve for feeding compressed air into the pressure chamber or discharging compressed air from the pressure chamber, and a compression spring device, the one end of which acts on the rolling piston or cover and the other end of which acts on the actuating device for the control valve and switches the latter depending on the pneumatic spring stroke, which pneumatic spring arrangement is characterized in that the compression spring device is configured at least in two pieces, with a central spring which faces the rolling piston or the cover and a control valve prestressing spring which faces the control valve, wherein the central spring is prestressed to a more pronounced extent than the control valve prestressing spring.
