Torsional vibration damper for damping torsional vibrations in an internal combustion engine comprises a boundary surface extending in a boundary region of the surface of a housing which is sealed with an elastomeric material

摘要

Torsional vibration damper comprises a boundary surface running between a closing part (6) and an edge of a closed opening and extending in a boundary region of the surface of a housing which is sealed with an elastomeric material in a fluid-tight manner to prevent the escape of viscous fluid from the housing. An independent claim is also included for a process for the production of the torsional vibration damper. Preferred Features: The boundary region is covered with the elastomeric material. One layer of the elastomeric material extends over the boundary region on the surface of the housing. A secondary mass is joined to a primary mass (1) via a spring element (22) made from an elastomeric material.
