ABSTRACT:
An impact damper which is equipped with an economical, cost-effective work piston, on which not only can a weight reduction be made, but also a substantial simplification in manufacture can be achieved. This impact damper is also designed to be deformable instantaneously upon collision with an obstacle when the force of the collision exceeds a predetermined range. The work piston is designed as a tubular body closed on a side facing a fluid containing chamber, and is provided with a breaking or buckling point, whereby energies can readily be absorbed, even at relatively high impact velocities.
