A vibration damper which is particularly suitable for vehicle seats. An inner cylinder (13) is divided by piston (23) into chambers (24) and (25) interconnected by passages (27) and (28) situated along the outer wall of the inner cylinder. Each passage has a one way valve (33), (36) to provide unidirectional fluid flow. A control valve (39), (40) controls the rate of oil flow and hence the damping rate. Body (12) interior (14) forms a reservoir around inner cylinder (13) into and out of which oil flows through relief valves (48, 50) to compensate for the volume of the chamber (24) occupied by piston rod (22). |
