Abstract

Damping element having a container tube, a piston mounted with freedom of movement in the damping medium-filled tube, a piston rod connected to the piston, and a fastening part for connecting the damping element to the first of the masses which are to be isolated from each other as effectively as possible with respect to vibration, where the piston rod is connected to the other of the masses. The fastening part includes a shaft and a fork, which serves to connect the fastening part to the first mass, where the fork is permanently connected to the shaft outside the area of the fork which is subject to dynamically alternating loads.
