ABSTRACT:
Viscous magnetic clutch for a radiator cooling fan which is electrically energized on closure of thermoswitch mounted within coolant of engine radiator. The clutch plate serves as a fluid pump to feed the viscous sheer area of the clutch so that conventional pump plate construction is eliminated. A drain hole within the clutch plate is controlled by magnetically operated valve mechanism on thermoswitch signal to provide for the retention or exhaust of fluid from the sheer area to provide for the selective hydraulic clutching or declutching of the fan and the drive.
