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.

Damper apparatus for use with vehicle torque converters are disclosed. A disclosed damper assembly for a vehicle torque converter includes a first portion operatively coupled to a clutch of the vehicle torque converter and configured to receive an engine torque from the clutch based on a state of the clutch. The damper assembly also includes a second portion and a hub rotatably coupled to a turbine of the vehicle torque converter. The damper assembly also includes a gear train including a ring gear coupled to the first portion, a planet gear rotatably coupled to the second portion, and a sun gear coupled to the hub. The damper assembly also includes a primary damping element positioned in a cavity formed by the second portion. Rotation of the first portion relative to the second portion compresses and decompresses the primary damping element to dampen a torsional vibration associated with the engine torque.
