Abstract
A hydrokinetic torque coupling device features a casing including a casing shell and an impeller casing shell, an impeller including the impeller shell, a turbine-piston including a turbine-piston shell, and a restriction element. The turbine-piston shell includes a turbine-piston flange and partitions the interior volume of the casing into two chambers. The turbine-piston flange has an engagement surface movable axially toward and away from an engagement surface of a piston engagement portion of the impeller shell to position the hydrokinetic torque coupling device into and out of a lockup mode. The restriction element is configured to restrict fluid flow and create a pressure drop between the first and second chambers.
