Abstract

504,214. Turbo-compressors. RHEINMETALL-BORSIG AKT.-GES. WERK-BORSIG BERLIN-TEGEL. Jan. 31, 1938, No. 2962. Convention date, Feb. 24, 1937. [Class 110 (i)] Flow-separation inside the delivery passages 8 of axialflow or radial-flow turbo-com. pressors is prevented by suction openings 12 between the leading and trailing edges of the rotor blades 6 connected by passages 11 with the gap 4 on the inlet side of the blades 6. Similar openings and passages may be provided in the guide blades 26 and the casing parts surrounding the rotor blades. The openings 9 of gap 4 may be nozzle-shaped and oblique. Additional passages may be formed between the inlet and outlet sides of rotor wheel 1. Passages 13 may be formed in the casing between the inlet openings 20 and nozzles 9<1>. The Specification as open to inspection under Sect. 91 comprises also the application of the suction openings 34 and passages 32 to the diffuser passage 35 of radial compressors. This subject-matter does not appear in the Specification as accepted.
