  • Bimetal activated viscous clutch with wiper on clutch disk
    Patent number: 9664238
    Abstract: Viscous fan drive systems with wiper members positioned on the OD of the clutch disks, and which rotate at high speed. The fluid reservoir also rotates at input speed. The wiper member directs viscous fluid radially back to the fluid reservoir. The valves in the viscous fan drive systems can be activated by a bimetal mechanism.
    Type: Grant
