Abstract
A fluid coupling assembly (11) in which the fluid coupling (43) is disposed within a coolant cavity (C) defined by an engine block (B) of an internal combustion engine. The fluid coupling includes an input coupling assembly (45) and disposed therein is an output coupling member (55), the input and output cooperating to define forward (61,65) and rearward (63,67) viscous shear areas to optimize torque capacity of the coupling. The input coupling assembly (45) includes a rearward body member (49) disposed within the cavity (C) and which includes impeller blades (73), such that the member (49) also serves as the water pump for the engine.
