ABSTRACT:
An impact-absorbing shock absorber with two telescoping tubes, in particular for motor vehicles, for decelerating, as a result of hydraulic damping forces and pneumatic spring forces, a vehicle which collides with an obstacle, has an inner tube closed by a bottom, a gas chamber adjacent to the bottom and containing a gas cushion at high pressure, a separating piston guided in a sealed manner so that it can move inside the inner tube, a first fluid chamber, a partition which has throttle openings, and a second fluid chamber which is connected via the throttle openings of the partition to the first fluid chamber. Above a defined energy absorption threshold, the partition is can be displaced from its original installed position toward the gas chamber, with an accompanying change in the shape of the inner tube.
