ABSTRACT:
A torque converter and viscous clutch has a viscous fluid chamber and a hydraulic fluid chamber. The fluid chambers are sealingly separated and physically interconnected by a piston interface. The piston interface is responsive to the thermal expansion in the viscous fluid chamber to permit expansion thereof. The piston is also responsive to increased pressure in the hydraulic fluid chamber to correspondingly increase the pressure in the viscous fluid chamber.
