ABSTRACT:
A shock absorber with a shock absorber body having a cylinder. A piston is moveably guided in a receiving space of the cylinder. When the piston is moved, an air pressure generated in the receiving space exerts a braking force that acts on the piston. For air pressure reduction, the receiving space has at least one opening that produces an air-carrying connection between the receiving space and the environment. The shock absorber body has a simple design if the piston or the cylinder contains a receptacle into which an insert piece is inserted in a frictionally engaging fashion and if the opening is positioned between the insert piece and the wall of the receptacle that is touched by the insert piece.
