Abstract
A torque converter features an impeller including an impeller shell and impeller blades, a turbine-piston including a turbine-piston shell and turbine blades, and a restrictor. The turbine-piston shell is axially displaceable relative to the impeller shell to position the torque converter (or a hydrokinetic torque coupling device containing the torque converter) into and out of lockup mode. The restrictor positioned radially outward of the impeller blades and the turbine blades at an opening of a fluid passage connecting the torus chamber to an environment outside the torque converter.
