The invention relates to a self-pumping air spring and damper unit for height adjustment of a vehicle body. The self-pumping air spring and damper unit can be articulated to the vehicle body by means of a first articulation point and to a wheel suspension by means of a second articulation point. The self-pumping air spring and damper unit comprises spring space filled with compressed air, which is bounded by a movable wall and which supports the two articulation points in a sprung manner relative to one another, and a damper cylinder, which can be connected to the spring space for fluid transmission by a connecting valve, is connected to one of the two articulation points and has at least two working spaces, which can be connected for fluid transmission by a throttle and which are separated by a working piston that is movable in the damper cylinder and is connected to the other of the two articulation points by a piston rod. The connecting valve and the throttle valve are each switchable valves, and one of the working spaces of the damper cylinder can be vented to the surrounding atmosphere via the switchable vent valve.
