Abstract
A torsional vibration damper has a hub part primary mass mountable on a motor drive shaft, and an interia ring secondary mass which at least partially encloses the hub part in the radially outer region. A gap between the hub part and the inertia ring is filled with fluid. A seal device between the hub part and the flywheel ring prevents escape of the fluid. The seal device has a first ring connected tightly to the hub part, a second ring connected tightly to the inertia ring, and an elastomer ring connected on one side sealingly to the first ring and on the other side to the second ring.
