Abstract

A flywheel arrangement has a first flywheel releasably connected with the crankshaft of an internal combustion engine, a second flywheel rotatable relative to the first flywheel, and a torque carrier including a torsional vibration damper disposed between the two flywheels in a chamber at least partially filled with a viscous medium. The chamber is bounded on its side facing the second flywheel by a cover plate, which cover plate coordinates preferably with a seal disposed in the radially inward region of the cover plate. The seal has a plurality of sealing elements disposed one after another in the discharge direction of the viscous medium, and the sealing elements are installed up to gap width on the respective associated components to be sealed, whereby at least one of these sealing elements is associated with a flow guide which is used to divert viscous medium into a return channel leading into the chamber.
