ABSTRACT:
A viscous fan clutch which employs a dynamic blocker ring positioned inside of the clutch between the pump plate and the clutch plate in such a manner that the fluid flow path is directed and not left to chance. The blocker ring, in effect, hydraulically separates the drive portion of the clutch from the pump and viscous fluid storage portion. The divider ring due to its location will provide support outboard of the bearing providing optimized durability.
