Claim Text:
1. A hydrokinetic torque coupling device for coupling a driving shaft and a driven shaft together, comprising: a casing rotatable about a rotational axis and comprising opposite first and second sidewalls, the casing further comprising an outer wall extending between and interconnecting the opposite sidewalls; an impeller coaxially aligned with the rotational axis and comprising an impeller shell; a piston engagement member extending substantially radially inward from and non-rotatable relative to the outer wall of the casing and being spaced between the opposite sidewalls of the casing, the piston engagement member having a first engagement surface; and a turbine-piston coaxially aligned with and hydrodynamically drivable by the impeller, the turbine-piston comprising a turbine-piston shell including a turbine-piston flange having a second engagement surface axially movable toward and away from the first engagement surface of the piston engagement member to position the hydrokinetic torque coupling device into and out of a lockup mode in which the turbine-piston is mechanically locked to and non-rotatable relative to the piston engagement member.
