A viscous fan clutch is provided to improve a cooling and driving performance by preventing the oil temperature from rising over 150 °C and maintaining a driving shear force. A viscous fan clutch(100) comprises a partition plate(10) formed with a pair of first oil ports for introducing oil, which divide the viscous fan clutch into an oil storage chamber and a rotor and a first valve(20), a guide portion connected between the pair of first oil ports, a second valve, and a bimetal(40). The first valve includes a second oil port(21), which is optionally communicated with the first oil port. The bimetal is installed to be guided along the guide portion and to be expanded according to the continuous operation of the clutch when the internal temperature of the viscous fan clutch increases. |
