Definitions

  • the invention relates to a device for atomizing or spraying or injecting liquid into an operating room according to the preamble of claim 1.
  • injectors in internal combustion engines have been known for a long time, such as in the EP 1 876 332 A1 .
  • WO 2011/028283 A1 US 2006/097077 A1 or US 2003/222159 A1 .
  • the DE 4 407 360 A1 can be seen that a flat fan beam can be rotated in the combustion chamber, so that the injected fuel quantity in the cylinder volume can be distributed to the amount of air available.
  • a flat fan beam can be rotated in the combustion chamber, so that the injected fuel quantity in the cylinder volume can be distributed to the amount of air available.
  • the object of the invention is in contrast to propose a device for atomizing or spraying or injecting liquid in an operating room, which eliminates the disadvantages of the prior art, at least by the line.
  • the orientation of the fan plane is adjustable by the offset between the center axes of the liquid jets in a flat fan beam.
  • a consuming rotatable nozzle as the document DE 4 07 60 1 revealed, dispensable. Consequently, both the constructive and the economic effort to realize a defined rotation of a flat Fan beam significantly improved according to the invention.
  • the orientation or the orientation of the fan level can be set and specified exactly according to the application.
  • a rotation or orientation is adjusted by approximately 45 °, as compared to the intersecting fan.
  • the orientation of the fan beam according to the invention or twisted at an offset X between zero and approximately the channel diameter surprisingly follows almost linearly, which is approximately expressed in the abovementioned two variants or straight line equations.
  • offset according to the invention is of advantage that the two colliding liquid jets or, the extensions of the two beam channels have sufficient coverage. This is taken into account by the abovementioned relationships or by the fact that the offset corresponds at most approximately to the channel diameter of one of the beam channels, that is to say twice the radius or the first radius of the beam first beam channel plus the second radius of the second beam channel, the latter may be relevant in particular for different radii. As a result, sufficient coverage and thus sufficient transmission of kinetic energy or the pulse is ensured to ensure, inter alia, an advantageous nebulization or spray of the liquid or the fuel.
  • a cross-section of the fan beam in the fan plane has substantially the shape of a triangle or a circular cutout.
  • the thickness or height of the fan beam transversely to the fan plane or transverse to the surface of the circular section is at most half as large as the width of the circular section.
  • the width of the Fan beam in the fan plane or the width of the circular section is about 5 times or 10 times to 100 times greater than the transverse extension or height of the fan beam transverse to Kreisausachnittsthesis or fan level.
  • the offset according to the invention in the impact zone can be realized, for example, by arranging the conical jet channels of the multiple jet nozzle not at a common plane, but at an acute angle to each other at this (imaginary) plane.
  • a first outlet opening of one of the jet channels for example, defines a plane with the central axis of the jet channel (ie thus also with the second outlet opening), but the central axis of the first jet channel comprising the first outlet opening is aligned at an angle to this plane.
  • an offset according to the invention results, so that a defined rotation or different orientation of the fan beam and thus of the fan level is set relative to the state in which the center axes of the liquid jets would intersect in the impact zone.
  • the rotation or the orientation can be set or fixed according to the invention.
  • the Mehrfachstrahldüse know outlet openings of the jet channels, wherein between the outlet openings of the offset is provided.
  • the two central axes of the liquid jets or the jet channels are arranged on two substantially parallel planes.

  • the preferably arranged on substantially parallel planes beam channels can be prepared in an advantageous manner.
  • a nozzle body is e.g. pierced by means of a laser beam or the like in an advantageous manner.
  • the offset according to the invention can be realized by a parallel adjustment of the nozzle body relative to the drill or laser beam in the amount of the offset according to the invention. This means that, for example, a first beam channel is produced and, by a transverse displacement / movement of the nozzle body or the laser or the like, the second beam channel is produced at a distance from the first beam channel, so that the distance corresponds to the offset according to the invention.
  • a jet channel is formed such that it is substantially a round cross-section and, for example, a diameter of about 100 to 300 microns, preferably about 150 microns. It has been found that such a small dimensioning of the / the jet channels just for use in an injector of an internal combustion engine is of great advantage.
  • the offset between the center axes of the liquid jets greater than zero and preferably greater than substantially 5% or 10% of one of the cana diameters to be provided or realized.
  • This is not only feasible in terms of production technology, but it also generates a relevant twist or change compared with the non-offset or non-twisted state. It has been found that minor inaccuracies, for example due to possibly limited production engineering possibilities, do not lead to any appreciable impairment with respect to the desired orientation of the flat fan beam and / or with regard to combustion in an internal combustion engine.
  • the offset between the center axes of the liquid jets substantially corresponds to a channel diameter or substantially up to twice the radius of one or more of the jet channels of the multiple jet nozzle, through which the respective liquid jet is guided. It has been shown that with such an embodiment or coverage of the colliding liquid jets advantageously an impulse transmission is generated, so that the fan plane of the flat fan beam according to the invention can be aligned. In this case, an advantageous, small droplet size is generated within the fan beam just by the momentum or the energy of the portions of the colliding liquid jets, which is advantageous for the nebulization or the injection of liquid, e.g. in the combustion chamber of an internal combustion engine.
  • droplet sizes of a few micrometers for example less than 10 or approximately 7 micrometer droplets, can be generated. This has an advantageous effect for the combustion and / or for a (rapid) evaporation of the liquid in the operating room.

  • a body of a nozzle body of the multi-jet nozzle comparatively close arranged body or a wall of the operating room can not be irradiated in an advantageous manner or sprayed or blasted on such a body or the wall over.
  • valves or flaps, protrusions, the movable piston or the like are present, for example, in a combustion chamber of an internal combustion engine, which should not be radiated as possible from the fan beam.
  • a nozzle body comprises at least a first multi-jet nozzle with the offset of the central axes of the liquid jets and at least one second multi-jet nozzle with a cutting or intersection of the central axes of the liquid jets.
  • the channel diameter of the jet channels of the multi-jet nozzle can be made different in size.
  • a first beam channel may have a channel diameter of about 150 microns and a second beam channel may have about 200 microns.
  • the energy transfer or the pulse for atomizing or atomizing can advantageously also be realized in the offset state in an advantageous manner.
  • the channel diameters of the jet channels of the multi-jet nozzle are substantially the same size.
  • the production of the multi-jet nozzle with very little effort can be realized.
  • one and the same tool can be used for production for all jet channels of the multi-jet nozzle.
  • a laser beam is used, which would have to be used or operated correspondingly differently for diameters of different sizes.
  • the dimensions of the offset according to the invention are substantially the same size Can channel diameters of the beam channels and thus the desired orientation or rotation can be better adjusted.
  • a nozzle body which has a defined longitudinal direction or longitudinal axis / geometric axis.
  • a multi-jet nozzle according to the invention can, for example, generate a conventional or a fan jet according to the invention in the longitudinal direction or extension of the nozzle body.
  • the fan level of the multi-jet nozzle is oriented transversely and / or inclined to the geometric axis or in the longitudinal direction of a nozzle body.
  • This measure is particularly advantageous in fuel or fuel applications or in an internal combustion engine.

  • the obliquely oriented orientation according to the aforementioned variant of the invention, e.g. several fan beams or their fan planes are aligned transversely to the longitudinal direction of the nozzle body, in particular in the manner of a flat disc and optionally with a single twisted fan beam.
  • This is for example of particular advantage in an arrangement of the nozzle body in the central or central region of the cylindrical operating space or combustion chamber.
  • a virtually uniform nebulisation or injection of the liquid or of the fuel into the cylinder space can be generated.
  • a certain clearance e.g. a valve opening or the like recessed, i. not be sprayed.
  • a plurality of multi-jet nozzles are distributed at least over a peripheral surface of a nozzle body aligned in the radial direction or about the longitudinal axis arranged. Accordingly, radial atomization can be realized nearly around the full circumference of the nozzle body, in particular substantially in the form of a flat disc with one or single twisted fan beams according to the invention.
  • a particularly large nebulization can be achieved, especially in a cylindrical operating space such as a combustion chamber of an internal combustion engine.
  • the very large surface of the (disc-shaped spread) atomized liquid droplets leads to a particularly rapid or rapid evaporation of fuel within the operating or combustion chamber. This has a positive effect, for example, in combustion processes in engines in a particularly advantageous manner in relation to the complete combustion of the end product or fuel.
