Abstract

1437105 Centrifugal compressors GENERAL MOTORS CORP 8 Nov 1973 [20 Nov 1972] 51836/73 Heading F1C An annular diffuser for a radial-flow compressor comprises substantially radial front and back walls 8, 16, a set of pivotable vanes 70 in a radially inner zone of the diffuser and a set of fixed vanes 63, 64, in a radially outer zone, diverging passages being formed between adjacent vanes in each set, each pivotable vane 70 increasing in thickness from the leading edge 72 and having a trailing edge 75 movable so as to engage the leading edges of two mutually adjacent fixed vanes 63, 64 so as to close the passage 68 between them and provide continuous diffusing passages 94, 67 through the vanes of the two sets, the trailing edges being movable away from the fixed vanes and towards the compressor axis upon pivoting of the pivotable vanes so as to define a diffuser for small flow between the pivotable vanes, and open the passages between all of the fixed vanes for unimpeded flow of the diffused gas. An abutment 92 on each vane 70 engages a vane 63 to limit and fix the open position of the vane 70. The vanes 70 are pivoted at 75 and are moved in unison by means of a ring 80 via pins 79 engaging slots 78. The ring 80 is located radially by a shoulder 83 on the wall 16 and the inner surface of a ring 66 and located axially by the vanes 70 and the wall 16, and is rotated by an actuating ring 84 via six posts 88 extending through circumferential slots 90 in the wall 16. The ring 84 is supported by three rollers 86. Variable guide vanes 34 vary the swirl in a convergent inlet 32. A heat insulation ring 60 is provided.
