Abstract
A multi-function torque converter including: an apply pressure chamber for a torque converter clutch; a first pressure chamber including a torus; and a resilient flow control element in fluid communication with the apply chamber and the first pressure chamber and arranged to control fluid flow to the apply pressure chamber. The resilient flow element is displaceable to block fluid flow to the apply pressure chamber in torque converter mode for the torque converter and to enable fluid flow to the apply chamber in lock-up mode. The torque converter includes a second pressure chamber and the clutch includes a piston plate at least partially bounding the apply pressure chamber and the second pressure chamber.
