Abstract

A torque converter, including: a cover; an impeller including an impeller blade, and an impeller shell with a first surface extending beyond the impeller blade in a radial direction and at an acute angle with respect to a first line in the radial direction; a turbine including a turbine blade, and a turbine shell with a second surface axially aligned with the first surface and at the acute angle with respect to the first line; a turbine clutch including the first and second surfaces and friction material disposed between the first and second surfaces; a torus at least partially enclosed by the impeller and turbine shells; and a pressure chamber at least partially formed by the turbine shell and the cover. For torque converter mode, the turbine and the impeller are independently rotatably with respect to each other. For lock-up mode, the first and second surfaces are non-rotatably connected.
