Abstract
A torsional vibration damper having a stator and a rotor provided with stator vanes and rotor wanes, respectively, which are arranged so as to form a plurality of work chambers fillable with damping medium and alternately changing their volumes during oscillation of the rotor. A damping device is provided in the rotor and has a compensation space in flow communication with the work chambers. The damping device has a throttle point configured so as to allow the compensation space to be pressurized by a relatively low pressure.
