Abstract

747,874. Rotary compressors. NICHOLS, T. W. Jan. 4, 1955 [Jan. 27, 1954], No. 2461/54. Class 110(2) In an outwardly-sliding vane type of compressor or pump the rotor 6 is free to move axially relatively to a driving shaft 9, and is provided with journals 7, 8, running in bearings. Oil passages through the shaft or rotor allow pressure on each end of the rotor to be equalized. The grooves, between shaft splines, may serve this purpose, being deep-cut. The oil, used for sealing and lubricating, may be led from an automatic control valve which shuts off the supply immediately the compressor stops running to prevent flooding of the working chamber. Water, for cooling purposes, may pass from an inlet 11 to an outlet 12.
