Abstract

Viscous fan coupling with refillable reserve chamber depending on the centrifugal force. It comprises a casing and at least one driveable rotor that, to transmit a torque through shear surfaces, is provided in a viscous liquid-filled working chamber which, to supply it with additional viscous liquid, has a function with the chamber reserve, at least one of the two chambers being connected, to prefix the degree of filling of the working chamber, with a pressure source by means of which it is possible to adjust the level of the viscous liquid that is established in the reserve chamber a position that prefixes the degree of filling. To guarantee the return of the viscous liquid from the working chamber, the reserve chamber is arranged radially outside of said working chamber, whereby the adjustment of the level of the viscous liquid can only be carried out depending on the magnitude and the direction of action of the pressure generated by the pressure source with respect to the action exerted on the viscous liquid by the centrifugal force caused by the number of revolutions.
