Title
(EN) Piston for torque transmitting systems
Abstract
(EN)

A device is provided for actuating force-receiving members of a torque transmission apparatus. The force-receiving members engage first and second rotatable members. The device includes a body with a working face adapted to apply a force to the force-receiving members, wherein at least a portion of the working face includes an arcuate surface.
