Abstract

1368205 Centrifugal pumps WESTINGHOUSE ELECTRIC CORP 3 Feb 1972 [1 March 1971] 5025/72 Heading F1C [Also in Division F2] A fan 10, for use at high temperatures, is mounted on a shaft 12 journalled in bearings 13, 14 and cooled by a medium (e.g. air) drawn along an axial hollow 15 in the shaft, closed adjacent the fan and pumped centrifugally by a radial tube 22, 23 from the hollow 15 when the shaft rotates. The tubes 22, 23 may serve as keys as shown.
