Abstract
A hydrokinetic torque coupling device includes a casing including a casing shell and an impeller shell, a piston engagement member non-rotatably coupled to the casing and having a first engagement surface, a turbine-piston including a turbine-piston shell partitioning an interior volume of the hydrokinetic torque coupling device into a torus chamber and a damper chamber and including a turbine-piston flange having a second engagement surface movable axially toward and away from the first engagement surface of the piston engagement member to position the hydrokinetic torque coupling device respectively into and out of a lockup mode, and a restricting washer disposed between the impeller shell and the turbine-piston shell for restricting a hydraulic fluid flow into and from the torus chamber for increasing a hydraulic fluid pressure in the torus chamber and pushing the turbine-piston shell toward the first engagement surface of the reaction plate.
