Definitions

  • the improvement consists in that the distance between the two parallel walls gradually increases from the center in radial direction in accordance with the increase of the thin layer of fluid that remains behind on the walls from where it may be discharged to the fluid reservoir via at least one interrupted or noninterrupted annular slotlike opening provided concentrically with the rotor.
  • the invention relates to a centrifugal fluid vanes compressor for making an effluvium move in the direction of rotation of the fluid vanes and for compressing it.
  • Such compressors are known in the art.
  • the vanes are thereby formed by a flowing fluid, which emerges at a high velocity through openings in a rapidly rotating driven rotor.
  • power is transmitted to the effluvium again and again trapped between two vanes.
  • the distance between the two walls bounding the compression chamber must at least be equal to the height of the vanes that must touch the wall.
  • H6. 1 is a cross-sectional view of one embodiment of fluid vanes compressor utilizing this invention.
  • HO. 2 is a cross-sectional view of a detail of the fluid vanes compressor of FIG. 1 in an enlarged scale.
  • the compressor shown in FIG. 1 comprises a compressor housing 1, which has been assembled with a fluid casing 2.
  • a rotor 3 Centrally in compressor housing 1 a rotor 3 has been mounted, which is mounted fixedly on a shaft 4, which is driven by an electromotor 7 via cogwheels and 6. Rotor 3 has been provided with blades 8 for suctioning an effluvium to be compressed, for example air, through a suction nozzle 9. Further rotor 3 has been provided with jets 10, which have been connected to a fluid supply duct 11, which via an adjustment device 12 has been coupled with a pump 13 which is connected to fluid casing 2.
  • the chamber within which the fluid vanes are formed is bounded by walls 14 and 15, which gradually diverge from the center.
  • annular slotlike opening which may be interrupted at certain places, can be provided for discharging of fluid remained behind on the walls, with the distance between the walls, immediately after the annular slotlike opening being substantially equal again to the distance in the center immediately after the rotor.
  • Both walls have, concentrically with respect to the rotor, been provided with annular slotlike openings 16 and 17, which have been connected to annular collecting channels 18 and 19. These collecting channels 18 and 19 are in open connection with fluid casing 2 via discharges 20 and 21.
  • Collecting chamber22 of the compressor is likewise in open connection with casing 2.
  • the compressed gaseous effluvium is separated from the fluid in casing 2 by ways known in the art with the aid of partitions 28 and then discharged via outlet 27.
  • FIG. 2 on a strongly enlarged scale a detail of the compressor is shown, from which it appears clearly that fluid vane 23 emerging from rotor 3 is bounded by fluid layers 24 and 25 formed on walls 14 and 15. These fluid layers are discharged via slotlike openings 16 and 17 to collecting channels 18 and 19, while via passage 26, of which the distance between walls 14 and 15 is again equal to the distance between the walls near rotor 3, the fluid vane is flung into collecting chamber 22 of the compressor.
  • a centrifugal fluid vanes compressor comprising:
  • a compression chamber having a central inlet for a gas
  • said rotor being provided with vanes for suction of gas through the central inlet and having jet channels extending therethrough;
  • a fluid supply duct including a fluid pump connected to the jet channels of the rotor
  • a fluid reservoir in open communication with the compression chamber and connected with the fluid pump
  • said reservoir having a discharge pipe for the compressed gas
  • said chamber having a pair of spaced walls disposed on opposite sides of the rotor and extending radially outwardly away from the rotor,
  • said walls being disposed such that the distance therebetween gradually increases over a major portion of the radial extent of said walls as the radial distance from the center of the chamber increases.
