Claim:
1. A device for influencing vibrations in a system including a first unit mounted to vibrate and a second unit mounted to be damped, the device comprising: a parallel circuit for direct or indirect attachment between the first unit and the second unit, the parallel circuit including a first force path through which a first force path acts and a second force path in parallel with the first force path through which a second force path acts, at least one elastically deformable element located in the first force path, at least one force generator located in the second force path including a lever having a first end and a second end, a first rotary bearing rotatably mounting the lever at the first end thereof about a first axis of rotation which is oriented orthogonally to both the first force path and the second force path, a second rotary bearing rotatably mounting the lever about a second axis of rotation which is oriented parallel to the first axis of rotation and the first axis of rotation and the second axis of rotation are spaced apart, a mass located at the second end of the lever which is mounted to vibrate, a first attachment for attaching the second rotary bearing to the first unit, a second attachment for attaching the first rotary bearing to the second unit, at least one of the first attachment and the second attachment upon attachment to the first and second units are linearly moveable relative to the first and second units by at least one actively controllable element which changes a moment of inertia of an end of the lever by altering a distance between the first axis of rotation and the second axis of rotation by altering a location of one of the first axis of rotation and the second axis of rotation relative to one of the first unit and the second unit.
