Abstract
A torque converter, including: a cover arranged to receive a rotational torque; an impeller including an impeller shell connected to the cover; a turbine including a turbine shell; a lock-up clutch including a piston plate; an output element arranged to non-rotatably connect to an input shaft of a transmission; and a flow control assembly including a seal plate defining a through-bore. The cover, the flow control assembly, and the piston plate define, at least partly, a release pressure chamber. The cover, the impeller shell, the piston plate, and the flow control assembly define, at least partly, an apply pressure chamber. In a clutch closed mode of the two-pass torque converter: the lock-up clutch is arranged to transmit the rotational torque to the output element; and a fluid in the apply pressure chamber is arranged to flow through the through-bore and into the release pressure chamber.
