Abstract
A lock-up clutch for a flow converter having pump and turbine blades which are hydraulically coupled, in which a ring piston is located between the converter cover and the turbine blades. The ring-piston and converter cover have mating conically shaped friction surfaces, thereby leaving a wedge-shaped space between the converter cover the turbine blades and the friction surface of the ring piston. An annular damper unit located in the wedge-shaped space has a plurality of damper elements which are coupled to the turbine vanes by fingers extending from the turbine vanes.
