ABSTRACT:
A viscous fan clutch employing flat wipers with angled edges secured on the inner annular periphery of the clutch body which scavage viscous fluid from the space between the inner diameter of the main body and the outer diameter of the clutch plate which controls the rate of discharge of pumping slots formed on the inside diameter of the body to optimize fluid flow from the working cavity to the storage cavity by way of a discrete intermediate cavity to reduce horsepower requirement when a low output speed during disengaged mode is desired or a faster rate of disengagement is required.
