Torque Converter Clutch System

A torque converter, comprising:

• a front cover configured to receive an input torque;
• an impeller having an outer shell non-rotatably connected to the front cover;
• a turbine fluidly coupled with the impeller;
• and
• a lock-up clutch disposed axially between the front cover and the turbine, the lock-up clutch comprising:
• a piston axially displaceable and including a first opening extending from a first axial side facing the front cover to a second axial side facing the turbine;
• a seal ring fixed to the front cover and sealed to the piston;
• a first fluid chamber formed at least in part by the piston and the turbine;
• a second fluid chamber formed at least in part by the front cover, the seal ring, and the piston;
• and
• a valve connected to the piston on the second axial side and configured to seal the first opening in response to a difference between a first pressure in the first fluid chamber and a second pressure in the second fluid chamber.
