Abstract:
A torque converter includes a front cover, an impeller assembly, a turbine assembly, a lock-up clutch, a backing plate, and a flow plate. The front cover is arranged to receive a torque. The lock-up clutch includes a piston and a seal plate disposed axially between the piston and a turbine shell. The backing plate is non-rotatably connected to the seal plate and is sealed to the piston. The flow plate is disposed axially between the backing plate and the front cover. The flow plate is non-rotatably connected to the backing plate and the front cover. A through-bore extends axially through the backing plate and the flow plate. 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.
