ABSTRACT:
In an oscillation damper with bypass between an annular working chamber and a compensating chamber, a shut-off valve is provided in the bypass. The shut-off valve is on the one hand exposed to the pressure in the annular working chamber and on the other hand to the pressure in a control chamber which is constructed directly adjacently to a valve shut-off element of the shut-off valve and is supplied by a throttle section with the pressure in the annular working chamber. The control chamber is constructed with a control chamber outlet. This control chamber outlet is opened or closed selectively by a cross section dimensioning module.
