Abstract
A torque converter includes a front cover arranged to receive a torque; an impeller non-rotatably connected to the front cover; a turbine in fluid communication with the impeller; a lock-up clutch having a piston and a seal plate disposed axially between the piston and the turbine. The torque converter further includes a flow plate non-rotatably connected to the front cover, and a backing plate sealed to the piston and disposed axially between the flow plate and the seal plate. A through-bore extends axially through the backing plate and the flow plate. The flow plate is welded to the backing plate around the through-bore. A first chamber is bounded at least in part by the piston, the seal plate, and the backing plate, and a second chamber is bounded at least in part by the front cover, the piston, the backing plate, and the flow plate.
