Abstract

In a horizontally and vertically acting vibration damper, there is arranged within the damper housing filled with damping medium a series of annular discs, at least one of which is assigned to the damper strut and which are horizontally and vertically movable relative to one another as a whole, the two movements being designated as telescopic. Some of the discs have at their outer edge a driver, so that the horizontal or radial movement of the annular discs can be transmitted to adjacent annular discs after a predetermined travel has been exceeded. By an appropriate calculation of the diameter of the discs, these can be arranged nested one in the other, so that, even with large movements, small constructional sizes are guaranteed.
