Abstract
A fan clutch assembly for a vehicle includes an electromagnetic control assembly for actuating a rotatable valve plate. A rotatable shaft is connected to the valve plate. A ferromagnetic element is slidably mounted on the shaft. When an electromagnetic coil is energized, the resulting flux attracts the ferromagnetic element. As the ferromagnetic element slides, it is rotated to cause rotation of the shaft, thereby opening the valve plate.
