Definitions

  • each nozzle unit 89 Positioned in each nozzle unit 89 is a nozzle member 92, illustrated in cross-section in Figure 10.
  • the periphery of the central portion 83 of the rotor 80 has a plurality of semicircular grooves 93 in alignment with the nozzle members 92.
  • a circumferential groove 94 extends on either side of the grooves 93.
  • the grooves 93, with the nozzle members 92, form an air turbine structure. Air admitted to a nozzle unit 89 is ejected by the nozzle member to impinge on the grooves 93 to produce a rotational effort on the rotor 80.
  • the nozzle units 89 are mounted in circular housings 95 welded to the housing 82.
  • Air under pressure, is fed to chambers 102 and 103 via inlets 107 and 108 respectively and to chambers 97 via one or more inlets 109. Air escaping by flowing down between the end of the central portion 83 of the rotor and inner wall 105 of end member 100, at the left side of Figure 8, can flow between the circumference of the reduced diameter portion 84 and the end member into chamber 110 and exhaust via outlet 111.
