ABSTRACT:
Vibration damper cylinder, in which a piston rod is guided with freedom of axial movement, where the cylinder has a compensating space, the volume of which is partially determined by an outer sleeve of a joint eye attached to the cylinder. The joint eye has an inner sleeve inside the outer sleeve, and where these two sleeves form a ring-shaped space, which is in flow connection with the compensating space.
