Abstract
A shock absorber has a cylinder with a piston and piston rod arrangement in the cylinder. Working medium can be guided in different flow paths via shim stacks for the purpose of obtaining different dampings based on the position of the piston. The piston arrangement can have a piston supporting shim stacks. One or more further shim stacks are arranged in a unit which is separate from the cylinder. In at least one of the shock absorber strokes, the working medium can be conveyed via the shim stack(s) in the unit separate from the cylinder.
