ABSTRACT:
A pneumatic spring and damper unit (1) has working chambers (2,3) which are filled with compressed air and are partially defined by rolled bellows or corrugated bellows. The working chambers are superimposed and connected through throttle valves, arranged inside a common pot-shaped cylindrical housing (4), and separated by a cylindrical piston (7), in such a way that one working chamber (2) is arranged on the front side of the piston and the other working chamber (3) is arranged on the rear side of the piston. The piston and the piston rod (5) are respectively sealed by roller bellows inside the cylindrical housing and guided therein, and the piston rod and the piston are interconnected by an articulation (6).
