ABSTRACT:
A hydrokinetic torque converter includes an impeller cover and a bypass clutch. A drive ring is located between adjacent surfaces of the cover and a clutch piston, which deflects flexurally axially. The piston is welded to the cover at a radially inner position, which is supported at another radial location on the cover. The piston deflects into engagement with the drive ring, and the drive ring engages with the cover. When clutch apply pressure is reduced, energy, in the form of elastic bending potential energy stored in the piston, is used to move the piston out of engagement with the drive ring and cover.
