Abstract
765,667. Screw fans. ROLLS-ROYCE, Ltd. Feb. 17, 1955 [Feb. 17, 1954], No. 4725/54. Class 110 (1). [Also in Group XXIX] A drive for a fan employed to pass a current of air through the matrix of a radiator for cooling the liquid coolant of an engine includes a hydrokinetic coupling in which liquid continually drains from the working chamber into a rotating reservoir in which a stationary scoop tube 23 is disposed for filling the coupling, a valve 30 regulating the flow from the scoop to the working chamber and being opened when a preselected coolant temperature has been reached to render the coupling effective. An impeller 13 is driven by a belt 14 from the engine, and is splined to a shaft 16 carrying a water pump impeller 17. A runner 12 is bolted to fan blades 10. The valve 30 is actuated by a thermostat capsule 31 in a chamber 32 through which the engine coolant is circulated by the impeller 17.
