Abstract
A torque converter including: a membrane forming a portion of a release chamber for the clutch; a friction plate for a torque converter clutch, the plate rotationally connected to a turbine hub and disposed within the release chamber; and a damper element rotationally connected to the turbine hub and to the torque converter clutch. In lock-up mode for the converter, the plate is arranged to transmit torque to the turbine hub. The torque converter includes cooling fluid and a torus and the clutch further comprises friction material and in some aspects, during the lock-up mode, the release chamber is sealed except for a flow of the cooling fluid from the release chamber through the friction material to the torus. The plate includes oppositely disposed first and second radial surfaces and during a torque converter mode for the torque converter, respective pressures on the first and second surfaces are substantially equal.
