Abstract
A torque converter comprises a front cover, an impeller including an impeller shell fixed to the front cover, and a turbine including a turbine shell axially movable to frictionally engage the impeller shell such that the turbine shell forms a piston of a lock-up clutch. A reaction plate is positioned axially between the front cover and the turbine shell. A first pressure chamber is defined axially between the reaction plate and the turbine shell, a second pressure chamber is defined axially between the turbine shell and the impeller shell, and a third pressure chamber is defined axially between the reaction plate and the front cover. An output hub includes a first bore and a second bore radially offset from each other, wherein the first bore is in fluid communication with the first pressure chamber and the second bore is in fluid communication with the third pressure chamber.
