Abstract
A torque converter, including: a cover; a pump fixedly secured to the cover; an axially displaceable turbine hydraulically coupled to the pump; and an axially displaceable stator at least partially disposed between the pump and the turbine and including a friction clutch with a plurality of clutch plates and respective friction material disposed between the plurality of clutch plates. When the ratio of the rotational speed of the turbine with respect to the rotational speed of the pump is less than a coupling point value, the turbine or the stator is arranged to axially displace to close the friction clutch. When the ratio of the rotational speed of the turbine with respect to the rotational speed of the pump is at least equal to the coupling point value: the stator or the turbine is arranged to axially displace to open the friction clutch; or the stator is arranged to axially displace to close the friction clutch.
