Abstract
A damping element for damping three-dimensional and torsional oscillations, in particular in hand tools, is proposed. The damping element includes an approximately bell-shaped rubber spring element defining a cavity which is filled with a damping fluid. The cavity is closed off at its open end with a rubber diaphragm. Within the cavity there is mounted at least one partition which defines overflow conduits or passages, and additional partitions at an angle to the partition defining the overflow conduits. The partition defining the overflow conduits is rigidly joined to a fastening sleeve situated in the rubber spring at the end thereof opposite to its open end.
