  • Patent number: 7802776
    Abstract: Disclosed is a pneumatic spring shock absorber unit having working chambers (2, 3), which are filled with compressed air and which are partially delimited by rolling or folding bellows (7, 8, 9). These working chambers are situated one above the other and are interconnected via throttle valves that can be flowed through. Both working chambers are located inside a common pot-shaped housing (4) and are separated by a piston (6) so that one working chamber (2) is located on the front side of the piston and the other working chamber (3) is located on the rear side of the piston and at least partially surrounds the piston rod (5) so that the piston and the piston rod are sealed and guided inside the housing by rolling bellows (7, 8, 9).
