Definitions

  • the present invention relates generally to liquid or fluid handling machines and relates more particularly to certain new and useful improvements in such machines having utility in pumps, motors, compressors and engines.
  • the invention is principally concerned with volumetric vane pumps in which the liquid, admitted through an inlet opening of a stator, is discharged by vanes of a rotor at an outlet opening.
  • the stator is peripheral
  • the rotor is offset in relation to the stator
  • the vanes are mounted for sliding movement in slots of the rotor.
  • the vanes undergo a reciprocating movement owing to their edges cooperating with the stator.
  • the rotational speed is limited to a relatively small value because of the friction, particularly of the vanes in their guides which increases very quickly with the speed, and also because of the deterioration of the conditions under which the intake takes place.
  • a volumetric pump constructed according to the present invention overcomes these drawbacks and cong sists of a rotor having wheels regularly arranged about the axis of roation thereof, each wheel being mounted for roation about an axis perpendicular to its plane.
  • the wheels For the discharge of the liquid to be put under pressure, the wheels have vanes which cooperate with passges in a stator, whose peripheral surfaces correspond to the paths of a part of the periphery of a vane during the composite movement resulting frm the rotor rotation in relation with the stator as well as from the rotation of the vane wheel about the axis on which it is mounted.
  • the covering of the passages is ensured by cooperation of the incurved surfaces of the stator adjacent to the passages with a mating cooperating surface of the rotor, from which the vanes of a wheel protrude for penetration into the passages.
  • the direction of rotation of a vane wheel about its axis corresponds to the path of a passage from its end nearest the rotor axis to that remote therefrom, the effect of centrifgual force being thus fa' vorable to the intake of the liquid into the passage and discharge from the passage.
  • Each vane wheel advanatageously comprises several vanes and the position in which a vane approaches a passage is strictly determined by another passage guiding another vane of the wheel cooperating with said other passagev
  • a rotor preferably includes several vane wheels disposed about its axis and at any instant a plurality of vanes circulate in the passage of the stator.
  • a pump according to the invention can turn at extremely high speeds.
  • the discharge of the pump is regular, thus avoiding the need for accessories that are frequently provided to control the flow at the outlet of the vane pump.
  • the construction provides radial balancing, so that high pressures can be reached without difficulty.
  • a generally discshaped rotor operates on both faces, each face supporting a series of vane wheels. The combination is thus axially balanced without using special means.
  • the present invention relates not only to driven machines functioning as pumps, but also to machines functioning as motors, the liquid exerting a force on the vanes housed in the pasages, which, by means of the wheels, puts the rotor carrying them into rotation.
  • Turbo-compressors such as the axial or centrifugal compressors, as well as the volumetric compressors, such as the piston, vane or other compressors, have drawbacks which heretofore have not been possible to overcome.
  • Turbo-compressors in spite of their high rotational speed, which requires large, bulky speed-reducing gear, do not enable hihg compression ratios to be obtained. In most cases, the compression has to be performed in several stages. Furthermore, the efficiency of turbo' compressors is acceptable only in a relatively narrow range of proportion of compressions ratio versus inlet flow rate.
  • a vane compressor constructed according to the invention enables better performances than those of the exisiting vane gas compressors from the point of view of roational speed and flow rate, as well as from the point of view of compression ratio.
  • the invention relates to a driven machine for compressible fluids or gas compressor, as well as driving machine, although the description herein below refers only to driven machines or gas compressors for simplification.
  • the present invention thus also consists in a gas compressor having a rotor comprising wheels regularly dis tributed about the axis of rotation thereof, each wheel being mounted for rotation about an axis which is perpendicular to its plane.
  • the said vane wheels include vanes cooperating with passages of the stator for the compression of the gas, their peripheral surfaces corresponding to the path of a portion of the periphery of a vane during the combined movement resulting from the rotor rotation relative to the stator, as well as the rotation of the vane wheels about the shafts on which
