ABSTRACT:
Disclosed is a vibration damper with an adjustable damping force and a method of producing the same. The adjustable vibration damper has a container tube to which is connected a shut-off valve arrangement. A damping medium is fed to the shut-off valve arrangement via a high-pressure partial length, an intermediate tube, if required, which is arranged inside the container tube, wherein the container tube and/or the intermediate tube with a cylinder in which a piston slides axially at a piston rod form the high-pressure partial length, and the container tube and/or the cylinder tube has a tube connection piece as a transition of the high-pressure partial length to the shut-off valve arrangement. The tube connection piece in at least one of the tubes forming the transition is constructed as a separate structural component part having a flange which contacts the inner region of the tube and projects through an opening in the tube.
