Abstract
A torque converter, including: a cover; a lock-up clutch with a piston plate; an output hub; a first hub including a through-bore; a chamber bounded by the turbine; an apply chamber bounded by the piston plate; a release chamber bounded by the cover, the first hub, and the piston plate; a first flow path; a through-bore through the first hub; and a second flow path. The second flow path: is sealed from the first chamber; passes through the through-bore; and includes a portion circumferentially aligned with the first flow path. A line in an axial direction passes through the through-bore without intersecting the first hub. For a lock-up mode, pressurized fluid in the apply chamber displaces the piston plate in a first axial direction. For a torque converter mode, pressurized fluid in the release chamber displaces the piston plate in a second axial direction.
