ABSTRACT:
In a double-tube vibration damper the working chamber adjacent the piston rod guide member is connected to the compensation chamber surrounding the cylinder through a by-pass valve. The by-pass valve is mounted in the cylinder or in a structural member stationary with respect to the cylinder. The by-pass valve has a cross-sectional area variable in dependency on a pressure signal or an electric signal. The damping characteristics of the vibration damper can be varied e.g. in dependency on the load charged onto the vehicle of which the vibration damper is a part.
