Patent ID: 8348036

Claim:
A multi-function torque converter comprising: a torque converter clutch including a piston plate; an apply pressure chamber for the torque converter clutch, the apply pressure chamber of the torque converter clutch at least partially bounded by the piston plate; a first pressure chamber including a torus, the first pressure chamber including an apply pressure chamber for a pump clutch; a second pressure chamber at least partially bounded by the piston plate and sealed with respect to the apply pressure chamber for the torque converter clutch; and, a resilient flow control element in fluid communication with the apply chamber for the torque converter clutch and the first pressure chamber and arranged to control fluid flow to the apply pressure chamber for the torque converter clutch and to the apply chamber for the pump clutch, wherein the piston plate is arranged to displace to close the torque converter clutch when fluid pressure in the apply chamber for the torque converter clutch is greater than fluid pressure in the second pressure chamber.
