Abstract: 731,822. Elastic-fluid turbines; centrifugal and axial flow compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 6, 1953 [March 14, 1952], No. 6753/52. Classes 110 (1) and 110 (3). An elastic fluid turbine or compressor having adjustable stator vanes operated together by a ring mounted within the casing actuated from outside of the casing by means passing through the casing in a fluid-tight manner has the ring split on one side to allow for thermal expansion. Gas from the volute 14, Fig. 1, passes to the radial inward flow turbine rotor 10 through a ring of nozzle vanes 11 which are tiltable about pivots 12 journalled in the turbine casing. The pivots 12 are arranged at about one-third of the length of the vanes from the outlet end of the vanes. The inlet ends of the vanes have pins 15 which engage a ring 17 which is freely supported on a spigot 35 of the casing in an annular recess 16. To prevent seizure due to thermal distortion the ring 17 is split at 18, Fig. 5. The inner surface of the ring is also recessed so that it contacts the spigot 35 only at spaced positions 19 which may be self-lubricating, e.g. graphite in character. The ring 17 is actuated by a shaft 23 from outside the casing through a pinion 22 which engages teeth 21 formed on part of the periphery of the ring. The ring 17 may be resiliently urged against the edges of the vanes 11 by springs or the split 18 may be made in a helical direction and the ring formed as part of a helix, in which case the natural resilience of the ring may urge it against the vanes 11. In a modification, the ring 17 is mounted on the spigot 35 by means of balls or rollers accommodated in recesses in the ring or spigot. Balls or rollers may be provided also on the outside surface of the ring. The application of the invention to an axial flow turbine or compressor is also described.
