Abstract
A shock absorber for damping the movement of the body of an automobile is provided. The shock absorber comprises a pressure cylinder forming a working chamber operable to store damping fluid. The shock absorber further comprises a reciprocating piston disposed in the working chamber operable to divide the working chamber into first and second portions. An axially extending piston rod is disposed within the working chamber and is connected to the piston. Finally, the shock absorber includes an annular collar and a split ring for controlling the displacement of the piston.
