Abstract
A torsional vibration damper includes two structural units rotatable relative to one another and linked to each other by a spring arrangement which includes at least one thrust piston. At certain angles of rotation between both structural units, the flow of force between the thrust piston of the spring arrangement and at least the secondary structural unit is realized via an outer surface area that engages the thrust piston, wherein the outer surface area is formed on a separate third structural unit which is resiliently mounted relative to the secondary structural unit.
