Abstract

650,393. Centrifugal pumps and compressors. BOWEN W. S. April 30, 1948, No. 11948. [Class 110(i)] A rotor for a pump, compressor or the like comprises a converging portion near the axis, an intermediate throat portion, and a diverging discharge portion. Each rotor of a two-stage compressor, Fig. 1, comprises discs 21, 22, 23, 24 which are dished to provide two Venturi passages for the fluid. Side discs 20, 25 are formed with labyrinth rings 40 which co-operate with similar stationary rings 39. Each rotor is followed by a Venturi stator p a s s a g e formed between walls 34, 35, and the discharge is by way of an annular passage 16. Oil and water may be injected through nozzles 37a and 38a, respectively. In the compressor shown in Fig. 2, the Venturi rotor passages are each formed by a converging part 48 and a diverging part 50 which leads the fluid inwardly towards a stator passage 53.
