An air spring assembly or air spring damper with an integrated valve control for controlling a level position of a vehicle or of a driver's cab includes a rolling tube, a lid and an air spring bellows which together delimit a pressure chamber with compressed air. A control valve includes an actuation device for feeding compressed air into the pressure chamber or for discharging compressed air from the pressure chamber. A compression spring device has a first end operatively connected to the rolling piston or the lid and a second end operatively connected to the actuation device. The compression spring device is configured with at least two parts including a central spring facing towards the rolling piston or the lid and a control valve biasing spring facing towards the control valve. The central spring is biased to a greater extent than the control valve biasing spring.
