ABSTRACT:
A shock absorber for a motor vehicle has a single-tube construction with an adjustable damping force. The shock absorber includes a cylinder tube and a piston rod guide inside which a piston rod with a piston is located so that the piston can move axially. The piston divides the cylinder tube into two work chambers. A container tube encloses the cylinder tube, at least in segments. Between the cylinder tube and the container tube at least one hydraulic connection, extending from one of the work chambers via an overflow orifice to a damping force adjustment valve located outside the container tube, is formed. A cylinder tube guide centers the cylinder tube with respect to the container tube. The damping force adjustment valve has two connection openings, one of which openings is separated from the other by a wall. The damping force adjustment valve is connected to the hydraulic connection, so that the container tube extends over the entire length of the hydraulic connection to the piston rod guide. The seal of the container tube is realized on the piston rod guide.
