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.
- an injection device is described in which two or more jets are generated in an injection nozzle, which intersect or collide in the combustion chamber.
- the purpose of this arrangement is that the high velocity fuel jet collide in the combustion chamber, thereby realizing extremely intense atomization of the fuel and thus comparatively small fuel droplets.
- 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 into an operating room, which at least partially eliminates the disadvantages of the prior art.
- a device according to the invention is characterized in that an offset between central axes of the liquid jets is provided in the impact zone.
- 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 according to the invention is substantially improved.
- the orientation or the orientation of the fan level can be set and specified exactly according to the application.
- 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 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 designed such that it has a substantially round cross-section and, for example, a diameter of approximately 100 to 300 micrometers, preferably approximately 150 micrometers. 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, to provide greater than substantially 5% or 10% of the channel diameter or realize.
- This is not only feasible in terms of manufacturing technology, but it also generates a relevant twist or change compared to 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 microns e.g. less than 10 or approximately 7 micrometer sized droplets are generated. This has an advantageous effect for the combustion and / or for a (rapid) evaporation of the liquid in the operating room.

- the offset is maximum approximately corresponds to the channel diameter of one of the beam channels, that is twice the radius or the first radius of the first beam channel plus the second radius of the second beam channel, the latter may be relevant in particular for different radii.
- a sufficient coverage and thus a sufficient transmission of kinetic energy or the pulse is ensured to provide, inter alia, an advantageous nebulization or spray of the liquid or the fuel safely.
- At least one predetermined free space of the operating space is recessed from the spray area of the multi-jet nozzle.
- 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 illuminated by the fan beam as possible.
- 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.

- This measure is particularly advantageous in fuel or fuel applications or in an internal combustion engine.
- the operating space or the combustion chamber is approximately cylindrical in such applications.
- 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 atomization or injection of the liquid or of the fuel into the cylinder chamber can be generated.
- a certain clearance e.g. a valve opening or the like recessed, i. not be sprayed.

- 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.
- the jet channels are at least partially aligned in the direction of a geometric axis or in the longitudinal direction of a nozzle body. So can be injected or atomized in the direction of the piston movement.
- FIG. 1 schematically a nozzle body 6 with a plurality of circumferentially arranged radially arranged multiple jet nozzles 1, each with two jet channels 2, 3 and their outlet openings 4, 5 and a separate section with a generated flat fan beam 7 with a fan plane P shown.
- the fan level P is the level or orientation or Alignment of the fan beam 7, in which the fan beam 7 is significantly or many times greater than in the (vertical) transverse direction, ie according to FIG. 1 in the direction of a longitudinal axis 8 of the nozzle body 8.
- the two beam channels 2, 3 are aligned along the longitudinal axis 8 of the nozzle body 6 and also at an acute angle to each other.
- FIG. 2 b) or FIG. 6 The acute-angled alignment of the jet channels 2, 3 is in FIG. 2 b) or FIG. 6 can be seen, in which schematically a nozzle 1 is sketched in side view.
- FIG. 2 b) Shown schematically are central axes 9, 10 of jet channels 2, 3, not shown, of a multi-jet nozzle 1 arranged in the longitudinal direction 8 or of a flat fan jet 7 (not shown). It can be seen that the extension of the central axes 9, 10 or the beam channels 2, 3 meet in an intersection point 11 and a baffle zone 12, respectively. This collision or collision leads to an advantageous nebulization or atomization of the liquids (jets) flowing through the jet channels 2, 3 and thus to a flat fan jet 7.
- the central axes 9, 10 are in FIG. 2 b) preferably aligned between approximately 10 ° and approximately 60 ° at an acute angle to the longitudinal axis 8.
- This nozzle 1 according to FIG. 2 (optionally) arranged in the longitudinal direction 8 at the lower end of the nozzle body 6 FIG. 2 b) has due to the selected page representation both in a nozzle 1 according to the prior art, the intersection 11 and in a nozzle 1 according to the invention with a transversely to the sheet / plane oriented offset 13 the intersection 11 of the central axes 9, 10. That is to say, the two liquid jets which are guided through the jet channels 2, 3 strike one another in the baffle zone 12 and generate the flat fan jet 7.
- a nozzle 1 according to the invention has an offset 13. That is, the beam channels 2, 3 or their central axes 9, 10 are at a distance from each other arranged, which corresponds to the offset 13.
- jet channels 2, 3 are aligned on planes which are essentially parallel to one another and are arranged vertically or in the longitudinal direction 8.
- inventive offset 13 of the central axes 9, 10 realized both in the area of the baffle zone 12 and between the two outlet openings 4, 5 as the distance 13.
- FIGS. 1, 2 and 4 to 6 the nozzles 1 and the outlet openings 4, 5 in the circumferential direction radially circumferentially or along the nozzle body 6 along horizontal circumferential lines 14, 15 and planes arranged.
- FIG. 6 a section along the upper line 14 and through the upper level, along or in which the upper, horizontally disposed beam channels 2 and whose center lines 9 are located.
- outlet openings 4, 5 are arranged in a recess 16, wherein the recess 16 is formed such that the outlet openings 4, 5 orthogonal to the jet channel 2, 3 and the center lines 9, 10 are aligned. As a result, an advantageous escape of the liquid jet is generated.
- FIG. 3 is a relationship between offset 13 and angle A shown schematically in particular for different pressures of the liquid.
- the Y-axis relates to the angle A, wherein the angle A of the angle of rotation or the orientation of the fan plane P of the flat fan beam 7 compared to the orientation or orientation of the fan beam 7 or its fan plane P without offset 13 (see. FIG. 1 ).
- the in FIG. 3 mapped 50% on the X-axis an offset 13 or X equal to the radius R and half the diameter D of the beam channel 2, 3.
- the angle A at an offset 13 in the size of the radius R is about 45 ° relative to the non-offset orientation (see. FIG. 1 ).
- This embodiment is in FIG. 4 shown.
- the beam channels 2, 3 are oriented horizontally along the lines 14, 15 and their planes, which is in FIG. 6 especially clarified.
- FIG. 5 shown a further embodiment, wherein the beam channels 2, 3 in turn horizontally along the lines 14, 15 and their planes are aligned, but have a distance of the lines 14, 15 and an offset 13, the diameter D of the beam channels 2, 3rd equivalent.
- the angle A is about 90 °. That is rotated by about 90 ° with respect to the orientation of the fan plane P with an arrangement of the beam channels 2, 3 without offset 13.
- the plane P would be aligned along the line 8, ie when the beam channels 2, 3 or central axes. 9 10 would lie on a common horizontal plane or perimeter line 14, 15.
- a comparison between the two FIGS. 1 and 5 also illustrates that the orientation or orientation of the fan level P in the end result may be the same, although a different orientation of the beam channels 2, 3 or their central axes and on the one hand an offset 13 (according to FIG. 5 ) in the size of the diameter D and on the other hand no offset 13 (according to FIG FIG. 1 ) is provided. Accordingly, the Orientation of the beam channels 2, 3 and the center axes 9, 10 are selected / specified depending on the need and / or space or the like. On the other hand, the orientation or orientation of the fan level P can be selected / determined as needed and / or desired exclusion of open spaces or the like.
- a (parallel) alignment of the beam channels 2, 3 or their central axes 9, 10 along the longitudinal axis 8 of the nozzle body 6 at relatively small nozzle body 6 and / or at relatively many nozzles 1 advantageous in the circumferential direction or along the Line 14, 15 are to order, for example to generate an almost complete nebulization or injection.
- the generation of spray fan or flat fan beams 7 by the collision of at least two individual beams can be realized in an advantageous manner by the described arrangements of the beam channels 2, 3 or holes 2, 3 of a nozzle pair and the orientation, penetration depth, Sauter diameter and / or Location of the generated spray fan 7 can be adjusted exactly.
- the position of the spray fan 7 is thus virtually freely positionable for the alignment or arrangement of the nozzle pair or the nozzle 1.
- Spray compartments generated by two or more bores 2, 3 form a spray fan 7, such as, inter alia FIG. 1 shown. Also, the Sauter diameter and the penetration depth are substantially the same. In order to effectively prevent wetting of the inlet / outlet valves, piston crown and cylinder wall or the like with liquid or the fluid, esp. Fuel, no spray fan 7 should be generated at these locations.
- the spray fan 7 can be changed by rotation / tilting of the nozzle 1 and the nozzle pair 1, but this must complete nozzle pair 1 can be arranged differently to generate this effect. For this often the necessary space is not given or must a larger death volume be created by eg a kind of "blind hole".
- the Sauter diameter and the penetration depth of the fan beam 7 can be adjusted to the application by the inclination of the beam channels 2, 3, the diameter D or the like in an advantageous manner.
- the coverage of the beams can be set in the range of> 0% to> 100%.
- the spray fan 7 rotates out of its (actual) position compared to the orientation without offset 13.
- the Sauter diameter and the penetration depth of the generated spray fan change.
- a particular advantage of this design of fan beams 7 is that targeted areas (inlet / outlet valves, piston crown, combustion chamber walls, etc.) can be recessed and thus not wetted with fuel. There is no coking of the components and the pollutant emissions are reduced. Wetting these parts in the combustion chamber leads to coking of said components and to an increase in pollutant emissions.
- Another advantage is the smaller footprint of a nozzle pair 1, which is designed according to the method or context according to the invention.
- a pair of nozzles 1 can still radially on Injector (nozzle area) are attached and produce a vertical instead of horizontal fan spray 7.
- the holes 2, 3 of the nozzle pair 1 with the same orientation of the fan beam 7 otherwise horizontal are introduced into the injector or nozzle body 6 in order to produce a fan spray 7 that is radially radial to the injector in a vertical position.
- the space of the nozzle pair 1 increases significantly.

Durch die in den Unteransprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.This object is achieved by a device of the aforementioned type, with the features of
Dementsprechend zeichnet sich eine erfindungsgemäße Vorrichtung dadurch aus, dass in der Prallzone ein Versatz zwischen Mittelachsen der Flüssigkeitsstrahlen vorgesehen ist.Accordingly, a device according to the invention is characterized in that an offset between central axes of the liquid jets is provided in the impact zone.
Es hat sich nämlich überraschenderweise gezeigt, dass durch den Versatz zwischen den Mittelachsen der Flüssigkeitsstrahlen bei einem flachen Fächerstrahl die Orientierung der Fächerebene einstellbar ist. Das heißt, dass der Versatz zwischen den Mittelachsen der Flüssigkeitsstrahlen eine Verdrehung der Fächerebene einstellt bzw. definiert. Hierdurch ist eine aufwendig drehbare Düse, wie dies die Druckschrift
So kann gemäß der Erfindung die Ausrichtung bzw. die Orientierung der Fächerebene je nach Anwendungsfall exakt eingestellt und vorgegeben werden.Thus, according to the invention, the orientation or the orientation of the fan level can be set and specified exactly according to the application.
Vorzugsweise weist ein Querschnitt des Fächerstrahls in Fächerebene im Wesentlichen die Form eines Dreiecks bzw. Kreisausschnittes auf. Die Dicke bzw. Höhe des Fächerstrahls quer zur Fächerebene bzw. quer zur Fläche des Kreisausschnittes ist höchstens halb so groß wie die Breite des Kreisausschnittes. Beispielsweise ist die Breite des Fächerstrahls in der Fächerebene bzw. ist die Breite des Kreisausschnittes um das ca. 5-fache oder 10-fache bis 100-fache größer als die quer gerichtete Ausdehnung bzw. Höhe des Fächerstrahls quer zur Kreisausachnittsfläche bzw. Fächerebene.Preferably, 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. For example, 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 Kreisausachnittsfläche or fan level.
Mit einem derartigen vorteilhaften sehr flachen Fächerstrahl, der gemäß der Erfindung in vorteilhafter Weise exakt ausgerichtet bzw. verdreht ist in Bezug zu einem Fächerstrahl, bei dem kein Versatz der Mittelachsen der Flüssigkeitsstrahlen vorgesehen ist, dass heißt in Bezug zu einem Fächerstrahl mit sich in der Prallzone schneidenden Mittelachsen der Flüssigkeitsstrahlen, kann eine definierte Zerstäubung bzw. Vernebelung erreicht und somit u.a. eine vorteilhafte Verbrennung von Kraftstoff in einem Verbrennungsmotor erreicht werden. Dementsprechend können gemäß der Erfindung sehr hohe Anforderungen an die Abgasqualität und an die Kraftstoffeinsparung bzw. Effizienz erfüllt werden.With such an advantageous very flat fan beam which is advantageously aligned according to the invention advantageously in relation to a fan beam, in which no offset of the central axes of the liquid jets is provided, that is with respect to a fan beam in the baffle zone Cutting central axes of the liquid jets, can achieve a defined atomization or nebulization and thus, inter alia An advantageous combustion of fuel in an internal combustion engine can be achieved. Accordingly, according to the invention, very high demands can be met on the exhaust gas quality and fuel economy or efficiency.
Der erfindungsgemäße Versatz in der Prallzone kann beispielsweise dadurch realisiert werden, dass die konisch zueinander ausgerichteten Strahlkanäle der Mehrfachstrahldüse nicht auf einer gemeinsamen Ebene, sondern zu dieser (gedachten) Ebene etwas spitzwinklig zueinander angeordnet sind. Das bedeutet, dass eine erste Austrittsöffnung eines der Strahlkanäle z.B. eine Ebene mit der Mittelachse des Strahlkanals (d.h. somit auch mit der zweiten Austrittsöffnung) definiert, jedoch die Mittelachse des die erste Austrittsöffnung umfassenden, ersten Strahlkanals winklig zu dieser Ebene ausgerichtet ist. Dementsprechend ergibt sich durch die Beabstandung der Austrittsöffnungen zur Prallzone ein erfindungsgemäßer Versatz, sodass eine gegenüber dem Zustand, bei dem sich die Mittelachsen der Flüssigkeitsstrahlen in der Prallzone schneiden würden, eine definierte Verdrehung bzw. unterschiedliche Orientierung des Fächerstrahls und somit der Fächerebene eingestellt wird. Hierbei kann durch eine Festlegung des spitzen Winkels zwischer der Mittelachse des o.g. ersten Strahlkanals zu der durch die Mittelachse des anderen bzw. o.g. zweiten Strahlkanals und der ersten Öffnung definierten (gedachten) Ebene, die somit beide Mittelpunkte der Austrittsöffnungen beider Strahlkanäle umfasst, die Verdrehung bzw. die Orientierung gemäß der Erfindung eingestellt bzw. festgelegt werden.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. This means that 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. Accordingly, due to the spacing of the outlet openings to the impact zone, 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. In this case, by fixing the acute angle between the center axis of the above-mentioned first beam channel and the second axis through the middle axis of the other Beam channel and the first opening defined (imaginary) plane, which thus comprises both centers of the outlet openings of both jet channels, the rotation or the orientation can be set or fixed according to the invention.
In einer besonderen Weiterbildung der Erfindung weißt die Mehrfachstrahldüse Austrittsöffnungen der Strahlkanäle auf, wobei zwischen den Austrittsöffnungen der Versatz vorgesehen ist. Vorzugsweise sind die beiden Mittelachsen der Flüssigkeitsstrahlen bzw. der Strahlkanäle auf zwei im Wesentlichen parallelen Ebenen angeordnet. So sind die beiden Ebenen in vorteilhafter Weise mit einem Abstand voneinander beabstandet, der dem Versatz gemäß der Erfindung entspricht.In a particular embodiment of the invention, the Mehrfachstrahldüse know outlet openings of the jet channels, wherein between the outlet openings of the offset is provided. Preferably, the two central axes of the liquid jets or the jet channels are arranged on two substantially parallel planes. Thus, the two planes are advantageously spaced apart with a distance corresponding to the offset according to the invention.
Die bevorzugt auf im Wesentlichen parallelen Ebenen angeordneten Strahlkanäle können in vorteilhafter Weise hergestellt werden. Beispielsweise wird ein Düsenkörper z.B. mittels eines Laserstrahls oder dergleichen in vorteilhafter Weise durchbohrt. Der erfindungsgemäße Versatz kann durch ein paralleles Verstellen des Düsenkörpers relativ zum Bohrer bzw. Laserstrahl im Maß des Versatzes gemäß der Erfindung realisiert werden. Das bedeutet, dass beispielsweise ein erster Strahlenkanal hergestellt wird und durch eine Querverstellung/-bewegung des Düsenkörpers bzw. des Lasers oder dergleichen der zweite Strahlkanal im Abstand zum ersten Strahlkanal hergestellt wird, so dass der Abstand dem Versatz gemäß der Erfindung entspricht.The preferably arranged on substantially parallel planes beam channels can be prepared in an advantageous manner. For example, 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.
Gemäß der Erfindung ist ein Strahlkanal derart ausgebildet, dass dieser im Wesentlichen einen runden Querschnitt und zum Beispiel einen Durchmesser von ca. 100 bis 300 Mikrometer, vorzugsweise ca. 150 Mikrometer, beträgt. Es hat sich gezeigt, dass eine derartige kleine Dimensionierung des/der Strahlkanäle gerade für einen Einsatz in einem Injektor einer Brennkraftmaschine von großem Vorteil ist.According to the invention, a jet channel is designed such that it has a substantially round cross-section and, for example, a diameter of approximately 100 to 300 micrometers, preferably approximately 150 micrometers. 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.
Generell ist von Vorteil, den Versatz zwischen den Mittelachsen der Flüssigkeitsstrahlen größer als Null und vorzugsweise größer als im Wesentlichen 5% oder 10% eines der Kanaldurchmesser vorzusehen bzw. zu realisieren. Dies ist nicht nur fertigungstechnisch umsetzbar, sondern es wird hierdurch auch eine gegenüber dem nicht-versetzten bzw. nichtverdrehten Zustand eine relevante Verdrehung bzw. Änderung generiert. Es hat sich gezeigt, dass kleinere Ungenauigkeiten, z.B. aufgrund ggf. begrenzter fertigungstechnischer Möglichkeiten, zu keiner nennenswerten Beeinträchtigung bzgl. der gewünschten Orientierung des flachen Fächerstrahls und/oder bzgl. der Verbrennung in einem Verbrennungsmotor führen.In general, it is advantageous, the offset between the center axes of the liquid jets greater than zero and Preferably, to provide greater than substantially 5% or 10% of the channel diameter or realize. This is not only feasible in terms of manufacturing technology, but it also generates a relevant twist or change compared to 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.
In einer vorteilhaften Variante der Erfindung entspricht der Versatz zwischen den Mittelachsen der Flüssigkeitsstrahlen im Wesentlichen bis zu einem Kanaldurchmesser bzw. im Wesentlichen bis zum doppelten Radius der oder eines der Strahlkanäle der Mehrfachstrahldüse, durch die/den der jeweilige Flüssigkeitsstrahl geführt ist. Es hat sich gezeigt, dass mit einer derartigen Ausführung bzw. Überdeckung der aufeinander prallenden Flüssigkeitsstrahlen in vorteilhafter Weise eine Impulsübertragung generiert wird, sodass die Fächerebene des flachen Fächerstrahls gemäß der Erfindung ausgerichtet werden kann. Hierbei wird gerade durch den Impuls bzw. die Energie der Anteile der aufeinanderprallenden Flüssigkeitsstrahlen eine vorteilhafte, kleine Tröpfchengröße innerhalb des Fächerstrahls generiert, was sich vorteilhaft für die Verneblung bzw. das Einspritzen von Flüssigkeit z.B. in den Brennraum einer Brennkraftmaschine auswirkt.In an advantageous variant of the invention, 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.
Grundsätzlich können gemäß der Erfindung Tröpfchengrößen von wenigen Mikrometer z.B. kleiner als 10 oder ca. 7 Mikrometer große Tröpfchen generiert werden. Dies wirkt sich vorteilhaft für die Verbrennung und/oder für eine (rasche) Verdampfung der Flüssigkeit im Betriebsraum auf.In principle, according to the invention, droplet sizes of a few microns, e.g. less than 10 or approximately 7 micrometer sized droplets are generated. This has an advantageous effect for the combustion and / or for a (rapid) evaporation of the liquid in the operating room.
Gemäß einer ersten, vorteilhaften Variante der Erfindung ist ein Winkel der Orientierung der Fächerebene im Vergleich zu einer Orientierung bei einem Schneiden der Mittelachsen der Flüssigkeitsstrahlen durch eine Dimensionierung des Versatzes derart eingestellt, dass im Wesentlichen A = X/D * 90° ist, wobei A der Winkel der Orientierung der Fächerebene ist und X der Versatz der Mittelachsen und D ein Kanaldurchmesser ist. In einer alternativen bzw. zweiten, vorteilhaften Variante der Erfindung ist der Winkel A derart eingestellt, dass im Wesentlichen A = 88° * X/D - 2,35° ist, wobei X der Versatz der Mittelachsen und D ein Kanaldurchmesser sowie X größer Null ist.According to a first advantageous variant of the invention, an angle of the orientation of the fan level is compared to an orientation in a cutting of the center axes of the liquid jets by dimensioning the offset is set such that substantially A = X / D * 90 °, where A is the angle of orientation of the fan plane and X is the offset of the center axes and D is a channel diameter. In an alternative or second advantageous variant of the invention, the angle A is set such that substantially A = 88 ° * X / D - 2.35 °, where X is the offset of the center axes and D is a channel diameter and X is greater than zero is.
Es hat sich in ersten aufwendigen Versuchen gezeigt, dass der Zusammenhang zwischen dem Winkel A, dass heißt einer Verdrehung des Fächerstrahls gegenüber einem Fächerstrahl mit sich schneidenden Mittelachsen der Flüssigkeitsstrahlen, gemäß den zuvor genannten Zusammenhängen bzw. Gleichungen näherungsweise sehr gut eingestellt werden kann.It has been shown in first elaborate experiments that the relationship between the angle A, that is to say a rotation of the fan beam with respect to a fan beam with intersecting central axes of the liquid jets, can be set approximately very well in accordance with the aforementioned relationships or equations.
Dementsprechend wird etwa bei einem Versatz X, der dem Radius eines Strahlkanals entspricht, im Vergleich zum sich schneidenden Fächer, eine Verdrehung bzw. Orientierung um ca. 45° verstellt realisiert. Die Orientierung des erfindungsgemäßen bzw. verdrehten Fächerstrahls bei einem Versatz X zwischen Null und etwa dem Kanaldurchmesser folgt überraschender Weise nahezu linear, was in den oben genannten beiden Varianten bzw. Geradengleichungen in etwa zum Ausdruck kommt.Correspondingly, in the case of an offset X, which corresponds to the radius of a beam channel, 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.
In zahlreichen Versuchen hat sich gezeigt, dass eine unterschiedlich starke Druckbeaufschlagung der Flüssigkeit nur zu vergleichsweise kleinen Schwankungen gegenüber den zuvor dargelegten Zusammenhängen bzgl. der Dimensionierung des Versatz und der Verdrehung bzw. Orientierung der erzeugten Fächerebene gemäß der Erfindung führt.Numerous experiments have shown that a different levels of pressurization of the liquid leads only to comparatively small fluctuations with respect to the above-described relationships regarding the dimensioning of the offset and the rotation or orientation of the generated fan level according to the invention.
Beim Versatz gemäß der Erfindung ist von Vorteil, dass die beiden aufeinanderprallenden Flüssigkeitsstrahlen bzw. die Verlängerungen der beiden Strahlkanäle eine ausreichende Überdeckung aufweisen. Dies wird durch die zuvor genannten zusammenhänge bzw. dadurch beachtet, dass der Versatz maximal etwa dem Kanaldurchmesser eines der Strahlkanäle entspricht, dass heißt dem zweifachen Radius bzw. dem ersten Radius des ersten Strahlkanals plus dem zweiten Radius des zweiten Strahlkanals, wobei letzteres insbesondere bei unterschiedlich großen Radien relevant sein kann. Hierdurch ist eine ausreichende Überdeckung und somit eine ausreichende Übertragung der kinetischer Energie bzw. das Impulses sicher gestellt, um u.a. eine vorteilhafte Vernebelung bzw. Versprayung der Flüssigkeit bzw. des Kraftstoffes sicher zu stellen.When 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 aforementioned relationships or by the fact that the offset is maximum approximately corresponds to the channel diameter of one of the beam channels, that is twice the radius or the first radius of the first beam channel plus the second radius of the second beam channel, the latter may be relevant in particular for different radii. In this way, a sufficient coverage and thus a sufficient transmission of kinetic energy or the pulse is ensured to provide, inter alia, an advantageous nebulization or spray of the liquid or the fuel safely.
Es hat sich in einzelnen Versuchen sogar gezeigt, dass durchaus der Versatz auch etwas größer als die Summe der beiden Radien der beiden Kanäle bzw. größer als ein Kanaldurchmesser ausgebildet werden kann. Die Bildung eines Fächerstrahls mit entsprechender Drehung wird trotzdem noch realisiert, da die Flüssigkeitsstrahlen nach dem Austritt aus dem jeweiligen Strahlkanal sich etwas aufweiten bzw. konisch sich ausdehnen, so dass diese sich in der Prallzone doch noch ein wenig überschneiden und zusammenprallen. Allerdings ist hier von größeren, erzeugten Flüssigkeitströpfchen im Fächerstrahl auszugehen.It has even been shown in individual experiments that quite the offset can also be formed slightly larger than the sum of the two radii of the two channels or larger than a channel diameter. The formation of a fan beam with appropriate rotation is still realized, since the liquid jets expand slightly after exiting the respective jet channel or expand conically, so that they still overlap and collide a little in the impingement zone. However, here larger, generated liquid droplets in the fan beam can be assumed.
Vorzugsweise ist wenigstens ein vorbestimmter Freiraum des Betriebsraumes aus dem Sprühbereich der Mehrfachstrahldüse ausgespart. Hiermit kann beispielsweise ein an einem Düsenkörper der Mehrfachstrahldüse vergleichsweise nahe angeordneter Körper bzw. eine Wand des Betriebsraumes in vorteilhafter Weise nicht angestrahlt bzw. an einem derartigen Körper bzw. der Wand vorbei gesprayt bzw. gestrahlt werden. Gerade bei Anwendungen in Brennkraftmaschinen oder dergleichen sind z.B. in einem Brennraum eines Verbrennungsmotors Ventile bzw. Klappen, Ausbuchtungen, der bewegliche Kolben oder dergleichen vorhanden, die möglichst nicht vom Fächerstrahl angestrahlt werden sollten. Ein entsprechendes Anstrahlen bzw. Niederschlagen des Fächerstrahls an entsprechenden Komponenten bzw. Wände des Betriebsraums führt zu einer nachteiligen Verbrennung, was in erhöhten Schadstoffmissionen resultiert. Aufgrund der immer steigenden Anforderungen an den Schadstoffausstoß von Verbrennungskraftmaschinen ist dies jedoch von entscheidendem Nachteil bzw. führt zu einem nicht akzeptablen Schadstoffausstoß.Preferably, at least one predetermined free space of the operating space is recessed from the spray area of the multi-jet nozzle. Hereby, for example, 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. Especially in applications in internal combustion engines or the like 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 illuminated by the fan beam as possible. A corresponding lighting or impingement of the fan beam on corresponding components or walls of the operating room leads to an adverse combustion, which results in increased pollutant emissions. Due to the ever increasing demands on the Pollutant emissions from internal combustion engines, however, this is a significant disadvantage or leads to an unacceptable pollutant emissions.
In einer vorteilhaften Ausführungsform der Erfindung umfasst ein Düsenkörper wenigstens eine erste Mehrfachstrahldüse mit dem Versatz der Mittelachsen der Flüssigkeitsstrahlen und mindestens eine zweite Mehrfachstrahldüse mit einem Schneiden bzw. Schnittpunkt der Mittelachsen der Flüssigkeitsstrahlen. Hierdurch ist eine vorteilhafte Anpassung an unterschiedlichsten Betriebsräume bzw. Verbrennungsräume/Brennkammern realisierbar. Je nach Anwendungsfall kann die Orientierung der Fächerstrahlen gemäß der Erfindung eingestellt werden. Hierdurch ist eine hohe Flexibilität an unterschiedlichste Betriebsbedingungen bzw. Betriebsräume realisierbar.In an advantageous embodiment of the invention, 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. As a result, an advantageous adaptation to a wide variety of operating rooms or combustion chambers / combustion chambers can be realized. Depending on the application, the orientation of the fan beams can be adjusted according to the invention. As a result, a high degree of flexibility can be realized in a wide variety of operating conditions or operating rooms.
Beispielsweise können die Kanaldurchmesser der Strahlkanäle der Mehrfachstrahldüse unterschiedlich groß ausgebildet werden. Beispielsweise kann ein erster Strahlkanal einen Kanaldurchmesser von ca. 150 Mikrometer aufweisen und ein zweiter Strahlkanal kann ca. 200 Mikrometer aufweisen. Mit dem erfindungsgemäßen Versatz kann hierbei die Energieübertragung bzw. der Impuls für das Zerstäuben bzw. Vernebeln in vorteilhafter Weise auch im versetzten Zustand in vorteilhafter Weise realisiert werden.For example, the channel diameter of the jet channels of the multi-jet nozzle can be made different in size. For example, a first beam channel may have a channel diameter of about 150 microns and a second beam channel may have about 200 microns. With the offset according to the invention, in this case the energy transfer or the pulse for atomizing or atomizing can advantageously also be realized in the offset state in an advantageous manner.
Vorzugsweise sind die Kanaldurchmesser der Strahlkanäle der Mehrfachstrahldüse im Wesentlichen gleich groß. Hiermit wird die Herstellung der Mehrfachstrahldüse mit besonders wenig Aufwand realisierbar. So kann für alle Strahlkanäle der Mehrfachstrahldüse ein und dasselbe Werkzeug zur Herstellung verwendet werden. Beispielsweise wird ein Laserstrahl verwendet, der bei unterschiedlich großen Durchmessern entsprechend unterschiedlich eingesetzt bzw. betrieben werden müsste.Preferably, the channel diameters of the jet channels of the multi-jet nozzle are substantially the same size. Hereby, the production of the multi-jet nozzle with very little effort can be realized. Thus, one and the same tool can be used for production for all jet channels of the multi-jet nozzle. For example, a laser beam is used, which would have to be used or operated correspondingly differently for diameters of different sizes.
Auch hat sich gezeigt, dass die erfindungsgemäße Dimensionierungen des Versatzes bei im Wesentlich gleichgroßen Kanaldurchmessern der Strahlkanäle und somit die gewünschte Orientierung bzw. Verdrehung besser eingestellt werden können.It has also been found that 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.
Beispielsweise wird gemäß der Erfindung ein Düsenkörper verwendet, der eine definierte Längsrichtung bzw. Längsachse/geometrische Achse aufweist. Eine Mehrfachstrahldüse gemäß der Erfindung kann beispielsweise in Längsrichtung bzw. Verlängerung des Düsenkörpers einen herkömmlichen oder einen erfindungsgemäßen Fächerstrahl erzeugen.For example, according to the invention, a nozzle body is used 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.
Vorzugsweise ist die Fächerebene der Mehrfachstrahldüse quer und/oder geneigt zur geometrischen Achse oder in Längsrichtung eines Düsenkörpers ausgerichtet. Diese Maßnahme ist vor allem bei Brennstoff- bzw. Kraftstoffanwendungen bzw. in einer Brennkraftmaschine von besonderem Vorteil. Der Betriebsraum bzw. der Brennraum ist bei derartigen Anwendungen in etwa zylinderförmig ausgebildet. Durch die quer bzw. geneigt ausgerichtete Orientierung gemäß der vorgenannten Variante der Erfindung können z.B. mehrere Fächerstrahlen bzw. deren Fächerebenen quer zur Längsrichtung des Düsenkörpers ausgerichtet werden, insbesondere in der Art einer flachen Scheibe und ggf, mit einem einzelnen verdrehten Fächerstrahl. Dies ist beispielsweise von besonderem Vorteil, bei einer Anordnung des Düsenkörpers im mittleren bzw. zentralen Bereich des zylinderförmigen Betriebsraumes bzw. Brennraumes. So kann beispielsweise eine nahezu gleichmäßige Vernebelung bzw. Einspritzung der Flüssigkeit bzw. des Kraftstoffs in den Zylinderraum generiert werden.Preferably, 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 operating space or the combustion chamber is approximately cylindrical in such applications. By 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. Thus, for example, a virtually uniform atomization or injection of the liquid or of the fuel into the cylinder chamber can be generated.
Gemäß der Erfindung kann bei derartigen Anwendungen in vorteilhafter Weise durch eine Verdrehung bzw. Änderung der Orientierung durch den erfindungsgemäßen Versatz ein bestimmter Freiraum, z.B. eine Ventilöffnung bzw. -klappe oder dergleichen ausgespart, d.h. nicht angesprüht werden.According to the invention, in such applications, by a rotation of the orientation according to the invention, a certain clearance, e.g. a valve opening or the like recessed, i. not be sprayed.
Vorteilhafterweise sind mehrere Mehrfachstrahldüsen wenigstens über eine in radialer Richtung bzw. um die Längsachse herum ausgerichtete Umfangsfläche eines Düsenkörpers verteilt angeordnet. Dementsprechend kann eine radiale Vernebelung bzw. Einspritzung nahezu um den vollen Umfang des Düsenkörpers verwirklicht werden, insbesondere im Wesentlichen in Form einer flachen Scheibe mit einem oder einzelnen verdrehten Fächerstrahlen gemäß der Erfindung. So kann eine besonders großflächige Vernebelung vor allem in einen zylinderförmigen Betriebsraum wie einen Brennraum einer Verbrennungskraftmaschine erreicht werden. Die sehr große Oberfläche der (scheibenförmig ausgebreiteten) vernebelten Flüssigkeitströpfchen führt zu einer besonders schnellen bzw. raschen Verdampfung von Brenn-/Kraftstoff innerhalb des Betriebs- bzw. Brennraumes. Dies wirkt sich beispielsweise bei Verbrennungsvorgängen in Motoren in besonders vorteilhafter Weise positiv im Bezug zur vollständigen Verbrennung des Endstoffs bzw. Kraftstoff aus.Advantageously, 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. Thus, 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.
Beispielsweise sind die Strahlkanäle wenigstens teilweise in Richtung einer geometrischen Achse oder in Längsrichtung eines Düsenkörpers ausgerichtet. So kann in Richtung der Kolbenbewegung eingespritzt bzw. verdüst werden.For example, the jet channels are at least partially aligned in the direction of a geometric axis or in the longitudinal direction of a nozzle body. So can be injected or atomized in the direction of the piston movement.

Die Generierung von Sprayfächern bzw. flachen Fächerstrahlen 7 durch das Aufeinanderprallen von mindestens zwei Einzelstrahlen, kann in vorteilhafter Weise durch die dargelegten geeigneten Anordnungen der Strahlkanäle 2, 3 bzw. Bohrungen 2, 3 eines Düsenpaares verwirklicht und die Ausrichtung, Eindringtiefe, Sauterdurchmesser und/oder Lage des generierten Sprayfächers 7 exakt justiert werden. Die Lage des Sprayfächers 7 ist somit quasi frei positionierbar zur Ausrichtung bzw. Anordnung des Düsenpaares bzw. der Düse 1.The generation of spray fan or flat fan beams 7 by the collision of at least two individual beams, can be realized in an advantageous manner by the described arrangements of the

Nachteil bisheriger Injektoren ist u.a. weniger Kraftstoff, schlechtere Kraftstoffverteilung, keine Variabilität bei Änderung der Anforderungen durch den Kunden.Disadvantage of previous injectors u.a. less fuel, less fuel distribution, no variability when customers change their requirements.
Der Sprayfächer 7 kann zwar durch Drehung/Kippen der Düse 1 bzw. des Düsenpaares 1 verändert werden, jedoch muss dazu das komplette Düsenpaar 1 anders angeordnet werden, um diesen Effekt zu generieren. Hierzu ist oftmals der notwenige Platz nicht gegeben bzw. muss ein größeres Todvolumen durch z.B. eine Art "Sackloch" geschaffen werden.Although the spray fan 7 can be changed by rotation / tilting of the

Die Sauterdurchmesser und die Eindringtiefe des Fächerstrahls 7 kann auf den Anwendungsfall durch die Neigung der Strahlkanäle 2, 3, dem Durchmesser D oder dergleichen in vorteilhafter Weise eingestellt werden. Je geringer die Überschneidung/Überdeckung der einzelnen Strahlen, d.h. je größer der Versatz 13, umso größer wird der Sauterdurchmesser. Die Überdeckung der Strahlen kann im Bereich von >0% bis >100% eingestellt werden.The Sauter diameter and the penetration depth of the fan beam 7 can be adjusted to the application by the inclination of the
Je nach %-Anteil der Überdeckung von mindestens zwei Strahlen dreht der Sprayfächer 7 im Vergleich zur Orientierung ohne Versatz 13 aus seiner (eigentlichen) Lage aus. Je geringer die Überdeckung umso höher/größer ist der Verdrehwinkel A des Sprayfächers 7. Gleichzeitig ändern sich der Sauterdurchmesser und die Eindringtiefe des generierten Sprayfächers.Depending on the% share of the coverage of at least two beams, the spray fan 7 rotates out of its (actual) position compared to the orientation without offset 13. The lower the overlap, the higher / greater is the angle of rotation A of the spray fan 7. At the same time, the Sauter diameter and the penetration depth of the generated spray fan change.
Besonderer Vorteil dieser Auslegung von Fächerstrahlen 7 ist, dass gezielte Bereiche (Ein-/Auslassventile, Kolbenboden, Brennraumwände, etc.) ausgespart werden können und somit nicht mit Brennstoff benetzt werden. Es findet keine Verkokung der Bauteile statt und die Schadstoffemissionen werden reduziert. Eine Benetzung dieser Teile im Brennraum führt zu Verkokungen der besagten Bauteile und zu einer Erhöhung der Schadstoffemissionen.A particular advantage of this design of fan beams 7 is that targeted areas (inlet / outlet valves, piston crown, combustion chamber walls, etc.) can be recessed and thus not wetted with fuel. There is no coking of the components and the pollutant emissions are reduced. Wetting these parts in the combustion chamber leads to coking of said components and to an increase in pollutant emissions.
Ein weiterer Vorteil ist der geringere Platzbedarf eines Düsenpaares 1, welches nach dem Verfahren bzw. Zusammenhang gemäß der Erfindung ausgelegt wird. Durch diesen gezielten Versatz 13 kann z.B. ein Düsenpaar 1 dennoch radial am Injektor (Düsenbereich) angebracht werden und einen vertikalen statt horizontalen Fächerspray 7 erzeugen. Ohne die erfindungsgemäße Auslegung müssten die Bohrungen 2, 3 des Düsenpaares 1 bei gleicher Ausrichtung des Fächerstrahls 7 ansonsten horizontal (vgl.
