Abstract
A hydrokinetic torque converter assembly has a turbine and an impeller located in a converter housing and a lockup clutch construction in the converter housing that includes a one-piece stamped clutch and piston housing secured to the inner wall of the converter housing wherein the outer extremity of the stamped housing carries friction discs. An annular piston is located between the discs and the converter housing wherein the piston is stroked toward the turbine upon introduction of control pressure to a control chamber defined by the piston and the cylinder, the driven discs of the clutch being connected to a turbine shaft through a damper and the friction elements of the clutch being continuously exposed to circulating fluid within the converter wherein piston charge pressure is established without a requirement for continuous flow when the clutch is actuated.
