Abstract

775,547. Centrifugal blowers and pumps; turbines. BUCHI, A. July 9, 1953 [July 12, 1952], No. 19088/53. Classes 110 (1) and 110(3). A contra-rotating blower or pump comprising an inner axial-radial flow stage discharging into a contra-rotating outer radial flow stage is driven by a turbine mounted on the shaft of one stage which is connected by gearing to the other stage; the ratio of the gearing being-other than 1 : 1 and so arranged that the inner stage rotates at a higher speed than the outer stage. The inner flow stage, Fig. 1, comprises rotors 1, 3 having radial flow and axial flow vane systems 2, 4 respectively. The outer flow stage consists of a rotor 9 carrying a radial flow vane system 11. The rotor 9 is carried by a shaft 8, 8<SP>1</SP> on which is mounted a two-stage turbine 43, 44. The rotors 1, 3 are carried by a shaft 5 which is driven from the shaft 8<SP>1</SP> by gearing 31, 32, 33 and 34, Fig. 2. The shaft 5 is mounted in an axial and radial bearing 21 and a bearing 28. The shaft 8, 8<SP>1</SP> is mounted in bearings 60, 61. A freely rotating bearing bush 29 may be located between the shaft 5 and shaft 8, 8<SP>1</SP>. Seals are provided to prevent leakage of working or lubricating medium. The gearing may comprise friction wheel drives or belt drives. A stationary vane system may be provided between the contra-rotating rotors.
