Abstract

1363525 Centrifugal blowers GES FUR ELEKTRISCHE GERATE mbH 29 Oct 1971 [31 Oct 1970 14 April 1971] 50399/71 Heading F1C [Also in Division H2] A lateral-duct blower 1 concentrically surrounding and driven by an electric motor 6, 7, has an impeller 5 having vanes 2 which pass over a lateral duct 19 formed in the housing 3, 4 so that a medium fed into the blower is drawn in one direction through the motor (between the stator 7 and rotor 6) and then in the opposite direction through a suction port 12 to the lateral-duct. The central disc 8 of the impeller 5 is driven by shaft 13 and has perforations 9 between vanes 10 forming an axial flow pre-compressor. Housing port 4 has a protective grid 18, and openings 16 between guide vanes 17 which co-operate with the axial flow blower. An exhaust port 15 is provided, generally adjacent the suction port 12. A sound absorbing liner 3', 4', may be provided on the inner surfaces of the housing and on the vanes 10. The impeller 5 and disc 8 may be formed as a single die cast unit or the disc may be a synthetic resin part pressed on a cast impeller, and the vanes 10 of disc 8 may be profiled so that the axial speed of the flow is the same at all radii. Two series connected lateral ducts (19, 19') Fig.6 (not shown) may be provided, a circular set of vanes (2, 2') passing over each duct.
