ABSTRACT:
The invention relates to a guide bushing between two components axially movable relative to each other, especially for guiding a piston rod subjected to longitudinal and transverse forces in the region of a piston rod seal of a hydropneumatic vibration damper. The guide bushing encompasses the piston rod, is held axially in a piston rod guide and is made of a material having good gliding characteristics. The guide bushing is arranged in the piston rod guide with a radial clearance having a gap with a changeable width when the piston rod is subjected to transverse forces created between the receptacle diameter of the piston rod guide and the outer diameter of the guide bushing.
