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 moves axially on a support surface. The piston is welded at a radially outer position to thin clutch plate, which is supported at another radial location on the cover. As the piston moves into engagement with the ring and cover, the clutch plate permits this movement by bending elastically. When clutch apply pressure is reduced, energy stored in the clutch plate is used to move the piston out of engagement with the drive ring and cover.
