Abstract

A device for damping vibrations comprising at least two coaxially arranged damper parts rotatable relative to each other to a limited extent in the circumferential direction, coupled by torque transmitting means and damping coupling means, which exhibit at least one energy accumulator unit, and forming the impingement areas for the energy accumulator units. At least one damper part forms a guide channel for the energy accumulator units. The individual impingement area on the damper part forming the guide channel for the energy accumulator units is formed by a stop element, connected in a torsion proof manner at least indirectly to the damper part and forms the abutment faces in the guide channel in the circumferential direction. The abutment face is capable of supporting the energy accumulator unit on both sides of the impingement area on the energy accumulator unit and is a part of the other damper part.
