Abstract

A torsional vibration damper (1) serving as a counterweight is prepared for the mass balancing of a rotating crankshaft, in particular, for an internal combustion engine. Said torsional vibration damper (1) is characterised in being fixed to the crank web (5) of the crankshaft and the centre of mass thereof is opposite the crankpin (4), relative to the axis of rotation of the crankshaft and having a liquid tight sealable working chamber (14) in which at least one secondary mass (19, 19') is housed which moves relative to the working chamber (14). The remaining volume and gap spaces (28) between the secondary masses (19, 19') and the walls (11, 12, 13, 21) of the working chamber (14) are filled with a viscous damping medium. Internal combustion engines can be fitted with the above torsional vibration damper (1) without an increase in the fitted length thereof.
