Abstract

1,049,976. Centrifugal fans. DAVIDSON & CO. Ltd. Nov. 5, 1965 [Nov. 18, 1964], No. 47002/64. Heading F1C. In a centrifugal fan having adjustable guide blades 22 in its inlet 12, an orifice 26 is positioned downstream of each guide blade to permit recirculation of the gases between the inlet and the impeller chamber 11 via an annular passage 29 containing inclined guide vanes 33. The inlet is polyhedral in cross-section but is contoured to substantially circular cross-section at its ends. Each guide blade carries at its end 24 a transverse plate 28 which during rotation of the guide blade runs closely adjacent or in contact with the surface of the inlet. The plate fully closes the associated orifice 26 when the guide blade approaches or reaches its fully opened position, and fully opens the orifice when the guide blade approaches or reaches its fully closed position. When in their fully closed position the guide blades do not entirely close the inlet.
