ABSTRACT:
An adjustable hydraulic vibration damper for motor vehicles includes a hydraulically and/or pneumatically adjustable control body of a damping valve which guarantees a continuous damping force adjustment, whereby when a control pressure falls below a minimum value, a high damping force is automatically generated. For this purpose, there is a control body for controlling passage of damping fluid through a flow channel, which control body has, on the side opposite the channel, a piston which works together with the control body, whereby a control pressure simultaneously presses against the neighboring end surfaces of the control body and of the control piston to provide a desired amount of damping force for control of the flow of damping fluid through the flow passage.
