Patent ID: 7225906

Claim:
A vibration damper comprising: a cylinder; a piston rod with a piston guided with freedom of axial movement in the cylinder, the piston dividing the cylinder into a first working space on a piston rod side and a second working space on a side away from the piston rod, which are at least partially filled with a damping medium; a further axially movable piston in the cylinder separating the second working space on the side away from the piston rod from a compensating space, which is filled with a compensating medium; and a joint eye bounding the compensating space, the joint eye having an outer sleeve fixed to the cylinder and an inner sleeve inside the outer sleeve, wherein the inner and outer sleeves of the joint eye are fixed relative to one another, the sleeves bounding a ring-shaped self-contained space which is in flow connection only with the compensating space in the cylinder.
