Abstract

The invention provides a single-tube vibration damper of variable damping force which consists of simple and easily produced components and permits problem-free assembly. This is achieved in that the cylinder comprises an open cylinder end provided with the cylinder diameter and is arranged therewith on the side remote from the piston rod exit in the container. The inflow passages for a damping device externally fitted on the container are formed by an annular space present between cylinder and container and divided by means of seal.
