Abstract

1445415 Axial-flow compressors MOTOREN-UND TURBINEN-UNION MUNCHEN GmbH 18 Sept 1973 [27 Sept 1972] 43847/73 Heading F1C A device for bleeding off compressor air in a gas turbine jet propulsion engine comprising a plurality of mechanically independent compressors, comprises an internal ring 20 provided with a first annular chamber 19 supplied with compressor air, the ring 20 being movable in axial and circumferential direction to expose openings of an external ring 22, thus permitting the air to flow into a second annular chamber 23 located outside the ring 22 and communicating with a by-pass duct 12 of the engine or with atmosphere, e.g. via hollow struts 16. As shown by arrows K, the air is bled from between the I.P. compressor 2 and the H.P. compressor 3. The ring 20 has inclined or helical guide slots 33 co-operating with guide rollers 34 mounted via eccentric adjustment pins 35 on the ring 22. Movement of ring 20 is effected by means of an actuating shaft 28 via levers 29, 30. Seals 25, 26, 27 and spherical bearings 31, 32 are provided.
