Abstract:
A temperature-controlled fluid coupling for intermittently driving a cooling fan of an internal combustion engine. The coupling comprises a drive input shaft having a rotor thereon, a housing for supporting a cooling fan, a plurality of radial vanes accommodated within the rotor, and a valve member within the housing. The vanes are movable in radial directions within an elliptic chamber in the housing. The rotor and the vanes provide a kind of vane pump system. A temperature sensitive element is disposed outside of the housing and connected to the valve member. The element operates to open and close the valve in response to a change of ambient temperature. The fan rotates to cool the engine only when the temperature goes up to a predetermined level.
