Because the fluid to be atomized flows through the supply ducts 22 at right angles to the plane of the drawing, each plate must have two duct openings 22, 22 so that a continuous supply duct is obtained on both sides of the nozzle chamber regardless of the orientation of the plate 17.
  • the fluids to be mixed
  • the desired mixing ratio can be obtained by the provision of different numbers of plates having different orientations.
  • An individual nozzle according to the invention having a plurality of inlets may l also be used for mixing a plurality of fluids if the various inlets are fed with the various fluids.

  • the first nozzle plate has circular openings and the succeeding nozzle plates have rectangular openings of progressively increasing area.
  • the last nozzle plate has a slot-shaped opening, which overlaps the underlying opening at two diametrically opposite corners to impart a special shape to the emerging spray.
  • FIGS. 2l and 22 Another possibility of controlling the shape of the spray is shown in FIGS. 2l and 22, in which the chamber consisting of identical or differently shaped plates 3 is divided in axial direction by one or more nozzle plates 4, which may have flow passage openings 24 of any desired shape in addition to the nozzle outlet 5.
  • FIG. 21 shows the division of the chamber by simple nozzle plates.
  • FIG. 22 shows the division by nozzle plates having tubular outlet extensions 25, which may be provided with peripheral openings 27 and/ or difusers. The lower outlet extension enters the upper one and for this reason is smaller in diameter than the latter.
  • the nozzle outlet openings 5 consist only of the outlet openings of the extensions 25 and of the slot formed in the uppermost nozzle plate 4 and exposed around the outlet extension.
  • the invention teaches to provide throttle openings 26 in the bottom and in the nozzle plates extending as far as to the housing wall.
  • the feeding to the various nozzle chambers may alternatively be effected in all cases by supply ducts extending through a side wall of the housing 7 surrounding the swirl generator (not shown in FIGS. 2l and 22) and opening into the clearance space 43 (FIG. 7). It is obvious that the inlet openings in the bottom of the housing 7 will be eliminated in this design. Protruding nozzle plates 4 (FIG. 21), which extend as far as to the housing wall, may be made without throttle openings.
  • a plurality of nozzles are arranged one behind the other and are connected by a central supply pipe 28 for the fluid to be atomized.
  • a spray of the atomized uid emerges from the annular slot S of each nozzle so that multiple sprays are obtained.
