Abstract

1,076,785. Centrifugal and mixed flow fans, compressors and pumps. JAMES HOWDEN & CO. Ltd. April 12, 1965 [April 15, 1964], No. 15564/64. Heading F1C. Fluid leaking through the clearance 14 between the cylindrical rim 8 of the impeller eye and the outlet 13 of an inlet guide 10 is guided towards the clearance by vanes 15. The vanes 15, which may be straight or curved and may project into the impeller eye, increase the efficiency and stability of the machine. The impeller may be of doubleinlet type.
