Abstract
A piston plate anti-rotate mechanism in a closed piston, three passage torque converter including a cover having an inner radial surface, a drive plate comprising an annular plate, a piston plate having an axial inner crown, a front annular edge, an axial skirt, and a back annular edge, wherein the cover, drive plate, and piston plate are operatively arranged to rotate about a transverse axis of rotation, and wherein the piston plate is attached to the cover or the drive plate such that the piston plate is axially moveable and rotationally immovable relative to the cover. In some embodiment, the present invention further includes a leaf spring attaching the piston plate to the cover or the drive plate, such that the piston plate is axially moveable and rotationally immovable relative to the cover.
