Abstract

In the case of a horizontally and vertically acting viscous vibration damper for damping vibrations of large masses exhibiting large amplitudes, at least one tube is disposed within the damper casing filled with viscous damping medium. Although this tube is able to move freely in the horizontal direction, i.e. parallel to the damper casing base, it is prevented from moving in the axial direction. The damping characteristics are thereby maintained, even in the event of vertical vibration movements.
