Abstract
Description
Die Erfindung betrifft eine Düse zum Zerstäuben einer Flüssigkeit mit einer Düsenöffnung, mit einer der Düsenöffnung vorgelagerten Rotationskammer, und mit mindestens einem tangential in die Rotationskammer einmündenden Rotationskanal zum Versetzen der Flüssigkeit in eine zur Düsenöffnung koaxiale Rotationsbewegung.The invention relates to a nozzle for atomizing a liquid having a nozzle opening, with a rotation chamber located upstream of the nozzle opening, and having at least one rotational channel opening tangentially into the rotation chamber for displacing the liquid into a rotational movement coaxial with the nozzle opening.
Eine derartige DĂĽse ist aus der
Hierbei ist von Nachteil, dass nur eine bestimmte minimale Tröpfchengröße erreichbar ist. Dies kann zu einer nicht optimalen Effektivität des Zerstäubers beispielsweise bei der Klimatisierung, beim Ausfiltern von Staub- und/oder Schmutzpartikeln und/oder beim Einsatz im Brandschutz führen.It is disadvantageous that only a certain minimum droplet size can be achieved. This can lead to a non-optimal effectiveness of the atomizer, for example in the air conditioning, the filtering of dust and / or dirt particles and / or use in fire protection.
Das der Erfindung zugrunde liegende Problem ist es, eine Düse der vorstehend genannten Art derart weiterzuentwickeln, dass eine geringere Tröpfchengröße erreichbar ist.The problem underlying the invention is to develop a nozzle of the aforementioned type such that a smaller droplet size can be achieved.
Zur Lösung des der Erfindung zugrunde liegenden Problems wird eine Düse der vorstehend genannten Art angegeben, wobei die Flüssigkeit mit einer der Düsenaustrittsrichtung entgegen gerichteten Komponente in die Rotationskammer einleitbar ist.To solve the problem underlying the invention, a nozzle of the aforementioned type is specified, wherein the liquid with one of the nozzle exit direction opposing component in the rotation chamber can be introduced.
Hierbei ist von Vorteil, dass sich auf überraschend einfache Weise eine erheblich größere Rotationsgeschwindigkeit der Flüssigkeit beim Austritt aus der Düsenöffnung ergibt. Aufgrund dieser höheren Rotationsgeschwindigkeit entsteht an der Düsenöffnung eine kegelförmige Verteilung des Sprühnebels mit erheblich geringeren Tröpfchengrößen. Somit lässt sich auch unter Verwendung des verhältnismäßig geringen Wasserleitungsdruckes eine sehr feine Vernebelung des Wassers erreichen.It is advantageous that results in a surprisingly simple way, a significantly greater rotational speed of the liquid at the exit from the nozzle opening. Due to this higher rotational speed, a conical distribution of the spray at considerably smaller droplet sizes is created at the nozzle opening. Thus, a very fine atomization of the water can be achieved even using the relatively low water line pressure.
Nach einer vorteilhaften Weiterbildung ist die in die Rotationskammer einströmende Flüssigkeit auf eine Rotationsbasis der Rotationskammer leitbar. Somit ist der in die Rotationskammer einmündende Rotationskanal einerseits mit einer Komponente entgegen der Düsenaustrittsrichtung und andererseits auf eine Rotationsbasis hin gerichtet. Aufgrund des tangential in die Rotationskammer einmündenden Rotationskanals bildet sich somit zunächst eine rotierende Fluid- bzw. Wasserscheibe auf der Rotationsbasis. Insbesondere wird die Flüssigkeit mittels des Rotationskanals fluchtend auf die Rotationsbasis geführt. Hierdurch werden die Entstehung einer turbulenzfreien Rotationsbewegung der Flüssigkeit begünstigt und unerwünschte Reibungsverluste reduziert. Vorteilhafterweise ist die Rotationsbasis der Düsenöffnung gegenüber angeordnet. Somit baut sich ausgehend von der Rotationsbasis in Richtung der Düsenöffnung eine rotierende Fluid- bzw. Wassersäule auf. Innerhalb der Wassersäule wirken auf die Moleküle geringere Reibungswiderstände als im Kontaktbereich zwischen der Wassersäule und der Wandung der Rotationskammer. Hierdurch kann sich innerhalb der Wassersäule eine größere Rotationsgeschwindigkeit als am Rand der Wassersäule einstellen.According to an advantageous development, the liquid flowing into the rotation chamber can be conducted to a rotation base of the rotation chamber. Thus, the opening into the rotation chamber rotation channel is directed on the one hand with a component opposite to the nozzle exit direction and on the other hand on a rotation basis. Due to the rotational channel which opens tangentially into the rotation chamber, a rotating fluid or water disk is thus initially formed on the rotation base. In particular, the liquid is guided in alignment with the rotation base by means of the rotation channel. This promotes the formation of a turbulence-free rotational movement of the liquid and reduces undesirable friction losses. Advantageously, the rotation base is arranged opposite the nozzle opening. Thus, starting from the rotation base in the direction of the nozzle opening, a rotating fluid or water column builds up. Within the water column lower friction resistances act on the molecules than in the contact area between the water column and the wall of the rotation chamber. As a result, a greater rotational speed can be set within the water column than at the edge of the water column.
Vorteilhafterweise ist die Rotationsbasis als eine kegelförmige oder halbkugelförmige Vertiefung oder als eine flache Ebene ausgebildet. Dies begünstigt einerseits die Entstehung der rotierenden Wasserscheibe beziehungsweise Wassersäule und andererseits wird aufgrund des größeren Wasservolumens die Ausbildung einer höheren Rotationsgeschwindigkeit der Wassermoleküle innerhalb der Wassersäule gefördert.Advantageously, the rotation base is formed as a conical or hemispherical recess or as a flat plane. On the one hand, this promotes the formation of the rotating water disk or water column and, on the other hand, due to the larger volume of water, the formation of a higher rotational speed of the water molecules within the water column is promoted.
Entsprechend einer Weiterbildung weist ein stromaufwärts von der Düsenöffnung angeordnetes Leitstück den Rotationskanal auf. Die Verwendung eines separaten Leitstückes erlaubt einen modulartigen Aufbau der Düse. Dieses erleichtert die Herstellung und den Austausch einzelner Elemente bei einem Defekt. Vorteilhafterweise setzt sich das Leitstück aus einem ersten Leitelement und einem zweiten Leitelement zusammen. Dies erleichtert vor allem die Herstellung des Rotationskanals, der Rotationskammer und der Rotationsbasis. So kann das erste Leitelement die Düsenöffnung, den Rotationskanal und einen ersten Teilbereich der Rotationskammer aufweisen. Somit ist die Düsenöffnung als eine feine Durchgangsbohrung, der Rotationskanal als eine Vertiefungsrille und der erste Teilbereich der Rotationskammer als eine Einsenkung vergleichsweise einfach herstellbar. Das zweite Leitelement kann die Rotationsbasis als zweiten Teilbereich der Rotationskammer aufweisen. Hierbei kann die Rotationsbasis als eine flache Ebene oder eine kegelförmige oder halbkugelförmige Vertiefung ausgebildet sein, welches ebenfalls ohne größeren Aufwand leicht und somit kostengünstig herstellbar ist. Durch eine geeignete Anordnung des ersten und zweiten Leitelementes zueinander bildet sich das Leitstück, welches den Rotationskanal und die Rotationskammer aufweist.According to a development, a guide piece arranged upstream of the nozzle opening has the rotation channel. The use of a separate guide piece allows a modular design of the nozzle. This facilitates the manufacture and replacement of individual elements in the event of a defect. Advantageously, the guide piece is composed of a first guide element and a second guide element. This facilitates above all the production of the rotation channel, the rotation chamber and the rotation base. Thus, the first guide element may have the nozzle opening, the rotation channel and a first subregion of the rotation chamber. Thus, the nozzle opening as a fine through-hole, the rotary channel as a recessed groove, and the first portion of the rotary chamber as a recess are relatively easy to manufacture. The second guide element may have the rotation base as the second portion of the rotation chamber. Here, the rotation base may be formed as a flat plane or a conical or hemispherical depression, which is also easy and thus inexpensive to produce without much effort. By a suitable arrangement of the first and second guide element to each other, the guide piece, which has the rotation channel and the rotation chamber.
Nach einer Weiterbildung nimmt die Höhe der Rotationskammer zur Rotationsachse der Rotationsbewegung hin zu. Dies kann einerseits dadurch erfolgen, dass der erste Teilbereich der Rotationskammer im ersten Leitelement als eine kegelförmige oder als halbkugelförmige Vertiefung ausgebildet ist. Alternativ oder zusätzlich kann die Rotationsbasis als eine kegelförmige oder halbkugelförmige Vertiefung ausgebildet sein. Hierdurch bildet sich unterhalb der Düsenöffnung eine vergleichsweise hohe innere Wassersäule mit einer sehr hohen Rotationsgeschwindigkeit, wobei diese innere Wassersäule im Wesentlichen die Rotationsachse bildet. Auf die diese Rotationsachse bzw. innere Wassersäule umgebende ebenfalls rotierende äußere Wassersäule wirken nur sehr geringe Reibungswiderstände.According to a further development, the height of the rotation chamber increases towards the axis of rotation of the rotational movement. On the one hand, this can take place in that the first subregion of the rotation chamber in the first guide element is designed as a conical or hemispherical depression. Alternatively or additionally, the rotation base may be formed as a conical or hemispherical recess. As a result, a comparatively high internal water column forms at a very high rotational speed below the nozzle opening, this inner water column essentially forming the axis of rotation. On the this rotating axis or inner water column surrounding also rotating outer water column only very low frictional resistance.
Entsprechend einer weiteren Ausführungsform ist auf der von der Rotationskammer abgewandten Seite des ersten Leitelementes eine kegelförmige oder kegelstumpfförmige Einsenkung oder ein Plateau koaxial zur Düsenöffnung ausgebildet. Hierbei ist von Vorteil, dass durch diese Einsenkung ein zylindrischer Teil des Düsenkanals als Teil der Düsenöffnung vergleichsweise kurz gehalten wird, wodurch unnötige Reibung vermieden wird. Dennoch ergibt sich eine ausreichende Festigkeit und Widerstandsfähigkeit des ersten Leitelementes gegen den Druck der Flüssigkeit. Bei der Ausgestaltung mit dem Plateau lässt sich eine Tropfenbildung auf der die Düsenöffnung umgebenden Stirnfläche des Leitelementes durch den Sprühnebel wirkungsvoll unterdrückenAccording to a further embodiment, on the side facing away from the rotation chamber side of the first guide element, a conical or frusto-conical depression or a plateau coaxial with the nozzle opening educated. In this case, it is advantageous that a cylindrical part of the nozzle channel is kept comparatively short as part of the nozzle opening by this depression, whereby unnecessary friction is avoided. Nevertheless, there is sufficient strength and resistance of the first guide element against the pressure of the liquid. In the embodiment with the plateau, droplet formation on the end face of the guide element surrounding the nozzle opening can be effectively suppressed by the spray mist
Vorzugweise sind mehrere, insbesondere zwei oder vier, Rotationskanäle vorgesehen. Die Rotationskanäle werden derart zueinander angeordnet, dass die Flüssigkeit möglichst gleichmäßig von allen Seiten der Rotationskammer in diese eingeleitet wird. Hierbei ist vorzugsweise der Wirkquerschnitt des Rotationskanals oder die Summe der Wirkquerschnitte der Rotationskanäle gleich oder größer dem Wirkquerschnitt der Düsenöffnung. Bei gleichem Wirkquerschnitt bzw. Leitwert treten von den Rotationskanälen bis zur Düsenöffnung keine Druckdifferenzen auf. Eine Expansion der Flüssigkeit und damit einhergehender Turbulenzbildung findet erst beim Austritt der Flüssigkeit aus der Düsenöffnung statt. Weist der Rotationskanal einen wesentlich größeren Wirkquerschnitt bzw. Leitwert als die Düsenöffnung auf, wird hierdurch die Austrittsgeschwindigkeit der Flüssigkeit erhöht. Dadurch lässt sich die Flüssigkeit noch feiner vernebeln.Preferably, several, in particular two or four, rotation channels are provided. The rotation channels are arranged to each other such that the liquid is introduced as uniformly as possible from all sides of the rotary chamber in this. In this case, the effective cross section of the rotational channel or the sum of the effective cross sections of the rotational channels is preferably equal to or greater than the effective cross section of the nozzle opening. With the same effective cross section or conductance, no pressure differences occur from the rotation channels to the nozzle opening. An expansion of the liquid and associated turbulence formation takes place only when the liquid exits the nozzle opening. If the rotation channel has a significantly larger effective cross section or conductance than the nozzle opening, the exit velocity of the liquid is thereby increased. As a result, the liquid can be atomized even finer.
Nach einer weiteren Ausführungsform nimmt ein Querschnitt des Rotationskanals von außen nach innen in Richtung der Rotationskammer, insbesondere in Bezug auf die Höhe und/oder die Breite des Rotationskanals ab. Hierdurch wird die Strömungsgeschwindigkeit der Flüssigkeit erhöht. Dies führt wiederum zu einer höheren Rotationsgeschwindigkeit der entstehenden Wassersäule, wodurch schließlich die Entstehung eines sehr feinen Sprühnebels begünstigt wird.According to a further embodiment, a cross-section of the rotation channel decreases from outside to inside in the direction of the rotation chamber, in particular with respect to the height and / or the width of the rotation channel. As a result, the flow velocity of the liquid is increased. This in turn leads to a higher rotational speed of the resulting water column, which ultimately favors the formation of a very fine spray.
Des Weiteren ist es von Vorteil, wenn die Düsenöffnung als ein Düsenkanal mit im Wesentlichen konstantem Wirkquerschnitt ausgebildet ist. Hierdurch wird ein rotierender Wasserzylinder, der im wesentlichen die Rotationsachse der gesamten rotierenden Wassersäule darstellt, aus dem Zentrum der Rotationskammer im wesentlichen laminar bis zum Austritt aus der Düsenöffnung geführt.Furthermore, it is advantageous if the nozzle opening is designed as a nozzle channel with a substantially constant effective cross-section. As a result, a rotating water cylinder, which essentially represents the axis of rotation of the entire rotating water column, is guided from the center of the rotation chamber substantially laminarly up to the exit from the nozzle opening.
Vorzugsweise entspricht die Länge des Düsenkanals dem Durchmesser der Düsenöffnung oder die Länge des Düsenkanals ist kleiner als der Durchmesser der Düsenöffnung. Hierdurch ergibt sich, insbesondere bei einer koaxial zur Düsenöffnung angeordneten kegelförmigen oder kegelstumpfförmigen Ausgestaltung des ersten Teilbereiches der Rotationskammer, eine besonders hohe Austrittsgeschwindigkeit der Flüssigkeit aus der Düsenöffnung. Hierbei wird mindestens ein Teil der Flüssigkeit von einem ersten der Rotationskammer zugewandten Bereich des Düsenkanals bzw. der Düsenöffnung zu einem diametral von der Rotationskammer und dem ersten Bereich abgewandten zweiten Bereich des Düsenkanals bzw. der Düsenöffnung geführt.Preferably, the length of the nozzle channel corresponds to the diameter of the nozzle opening or the length of the nozzle channel is smaller than the diameter of the nozzle opening. This results in a particularly high exit velocity of the liquid from the nozzle opening, in particular in the case of a conical or frusto-conical configuration of the first subarea of the rotary chamber arranged coaxially with the nozzle opening. Here, at least a part of the liquid from a first of the rotation chamber facing the region of the nozzle channel or the nozzle opening to a diametrically remote from the rotation chamber and the first region second region of the nozzle channel and the nozzle opening.
Nach einer Weiterbildung weist das Leitstück dem Rotationskanal oder den Rotationskanälen jeweils über die volle axiale Länge des Leitstücks zugeordnete Speisekanäle auf. Durch die Speisekanäle ergibt sich eine einfach herzustellende Wasserversorgung für die Rotationskanäle. Vorzugsweise ist eine in dem Leitstück zwischen dem Rotationskanal und dem zugeordneten Speisekanal ausgebildete erste Ausgleichskammer vorgesehen. Hierdurch lassen sich Druckschwankungen und Geschwindigkeitsverluste durch turbulente Strömung einfach ausgleichen.According to a development, the guide piece on the rotation channel or the rotation channels in each case over the full axial length of the Leitstücks associated feed channels. Through the feed channels results in an easy to produce water supply for the rotation channels. Preferably, a first compensation chamber formed in the guide piece between the rotation channel and the associated feed channel is provided. This makes it easy to compensate for pressure fluctuations and speed losses due to turbulent flow.
Entsprechend einer weiteren Ausführungsform ist ein Druckstück zum Fixieren des Leitstückes vorgesehen. Hierbei ist von Vorteil, dass sich mittels dieses Druckstückes das Leitstück in einer vorbestimmten Position zu der Düsenöffnung fixieren lässt. Ein Sinterfilter kann die Funktion des Druckstückes übernehmen. Vorzugsweise weist das Druckstück mehrere den Speisekanälen jeweils zugeordnete Bohrungen auf und zwischen den Bohrungen und den Speisekanälen ist eine zweite Ausgleichskammer angeordnet. Die Zuführung des Fluids erfolgt hierbei im Wesentlichen kreisringförmig. Somit wird auch bei Fixierung des Leitstückes mit dem Druckstück eine ausreichende Wasserzufuhr ohne größeren Aufwand gewährleistet.According to a further embodiment, a pressure piece for fixing the guide piece is provided. It is advantageous that can be fixed by means of this pressure piece, the guide piece in a predetermined position to the nozzle opening. A sintered filter can take over the function of the pressure piece. Preferably, the pressure piece has a plurality of the feed channels respectively associated holes and between the holes and the feed channels a second compensation chamber is arranged. The supply of the fluid takes place in this case substantially annular. Thus, a sufficient supply of water is ensured without much effort even when fixing the Leitstückes with the pressure piece.
Nach einer Weiterbildung ist ein Gehäuse zum Aufnehmen der Düse mit einem Innengewinde vorgesehen, wobei das Innengewinde mit einem Außengewinde des Druckstückes in Eingriff steht. Somit lässt sich die Düse durch einfaches Einlegen des Leitstückes in das Gehäuse und anschließendes Einschrauben des Druckstückes montieren. Vorzugsweise ist das Gehäuse und das Leitstück, insbesondere das erste Leitelement, einstückig hergestellt. Bei einer Materialverwendung von beispielsweise Edelstahl und/oder einem Edelstahl-Spritzgussverfahren lässt sich dieses kombinierte Bauteil auf einfache und günstige Weise herstellen. Hierdurch ist eine kostengünstige Düse herstellbar, die beispielsweise für den Brandschutz einsetzbar ist. Alternativ kann bei einer zweiteiligen Gestaltung von Gehäuse und Leitstück, insbesondere erstem Leitelement, das Leitstück und/oder das erste Leitelement aus Keramik hergestellt werden. Hierdurch ist eine erhöhte Abrasionsfestigkeit realisierbar. Somit wird eine dauerhafte Funktionstüchtigkeit auch bei einer dauerhaften und/oder regelmäßigen Verwendung der Düse, wie beispielsweise zum Klimatisieren und/oder zum Ausfiltern von Staub- und Schmutzpartikeln, gewährleistet.According to a development, a housing for receiving the nozzle is provided with an internal thread, wherein the internal thread is in engagement with an external thread of the pressure piece. Thus, the nozzle can be mounted by simply inserting the Leitstückes in the housing and then screwing the pressure piece. Preferably, the housing and the guide piece, in particular the first guide element, made in one piece. When using materials such as stainless steel and / or a stainless steel injection molding process, this combined component can be produced in a simple and inexpensive way. As a result, a cost-effective nozzle can be produced, which can be used for example for fire protection. Alternatively, in a two-part design of the housing and the guide piece, in particular the first guide element, the guide piece and / or the first guide element made of ceramic can be produced. As a result, an increased abrasion resistance can be realized. Thus, a permanent operation is guaranteed even with a permanent and / or regular use of the nozzle, such as for air conditioning and / or filtering out dust and dirt particles.
Von besonderem Vorteil ist die Verwendung der erfindungsgemäßen Düse zum Klimatisieren, zum Ausfiltern von Staub- und/oder Schmutzpartikeln und/oder für den Brandschutz.Of particular advantage is the use of the nozzle according to the invention for air conditioning, for filtering dust and / or dirt particles and / or for fire protection.

Der Zylinder 20 weist Rotationskanäle 13, 14 auf, die als Nuten beziehungsweise Einkerbungen ausgebildet sind. Die Rotationskanäle 13, 14 führen von außen kommend tangential in einen ersten Teilbereich einer Rotationskammer 15, wobei der erste Teilbereich der Rotationskammer 15 als eine im Wesentlichen kegelförmige Vertiefung um die Düsenöffnung 11 ausgebildet ist. Die Rotationskanäle 13, 14 sind derart ausgebildet, dass die Vertiefung von außen nach innen gehend, also in Richtung auf den ersten Teilbereich der Rotationskammer 15, abnimmt.The
Auf der von dem ersten Teilbereich der Rotationskammer 15 abgewandten Seite des Leitelementes 10 ist eine im Wesentlichen kegelförmige Einsenkung 18 koaxial zur Düsenöffnung 11 ausgebildet.On the side facing away from the first portion of the
Ein Leitstück 31 setzt sich aus einem ersten Leitelement 32 und einem zweiten Leitelement 33 zusammen. Hierbei ist das erste Leitelement 32 in dem Gehäuse 28 eingesetzt, während das zweite Leitelement 33 mittels des Druckstückes 29 in einer kreisscheibenförmigen Aufnahme des ersten Leitelementes 32 gehalten wird. Das zweite Leitelement 33 weist eine im Wesentlichen kreisscheibenförmige Gestalt auf, wobei an der Außenumfangsfläche des zweiten Leitelementes 33 mehrere gleichmäßig beabstandete Vertiefungen oder Rillen als Speisekanäle 34 vorgesehen sind. Die Speisekanäle 34 gehen in eine mittels des ersten Leitelementes 32 gebildete kreisringförmige erste Ausgleichskammer 36 über. Hiervon ausgehend ergeben sich Rotationskanäle 35, die die Flüssigkeit mit einer der Düsenaustrittsrichtung entgegen gerichteten Komponente auf eine ebene Rotationsbasis einer Rotationskammer 37 leiten. Hierbei verjüngen sich die Rotationskanäle 35 in Richtung auf die Rotationskammer 37 bzw. die Rotationsbasis.A
Die Düse 38 weist ein Leitstück 42 auf, welches sich aus einem ersten Leitelement 43 und einem zweiten Leitelement 44 zusammensetzt. Im Gegensatz zur Düse 26 ist hier das erste Leitelement 43 integraler Bestandteil des Gehäuses 39. Das erste Leitelement 43 und das Gehäuse 39 sind in dem hier gezeigten Ausführungsbeispiel einstückig ausgebildet.The
Das zweite Leitelement 44 ist teilweise innerhalb einer Bohrung 45 in dem Druckstück 40 angeordnet. Hierbei liegt das zweite Leitelement 44 auf einer ersten Seite fest an dem ersten Leitelement 43 bzw. dem Gehäuse 39 an, während es auf einer von dem ersten Leitelement 43 abgewandt liegenden zweiten Seite auf Schultern 46 des Druckstückes 40 aufliegt. Das zweite Leitelement 44 weist auf seiner Außenumfangsfläche mehrere gleichmäßig beabstandete Speisekanäle 47 auf. Die Speisekanäle 47 gehen in eine mittels des ersten Leitelementes 43 gebildete kreisringförmige erste Ausgleichskammer 53 über. Hiervon ausgehend ergeben sich Rotationskanäle 54, 55, die die Flüssigkeit mit einer der Düsenaustrittsrichtung entgegen gerichteten Komponente auf eine ebene Rotationsbasis 48 einer Rotationskammer 56 leiten. Hierbei verjüngen sich die Rotationskanäle 54, 55 in Richtung auf die Rotationskammer 56 bzw. die Rotationsbasis 48. Dabei ist die Rotationsbasis 48 an der von dem Druckstück 40 abgewandten ersten Seite des zweiten Leitelementes 44 angeordnet.The
An dem von der Rotationsbasis abgewandten Ende des zweiten Leitelementes 44 ist eine weitere Bohrung 49 in dem DruckstĂĽck 40 vorgesehen, wobei der Durchmesser der weiteren Bohrung 49 kleiner ist als der Durchmesser der Bohrung 45. Innerhalb der Bohrung 49 ist eine Feder 50 angeordnet, die sich an dem zweiten Leitelement 44 abstĂĽtzt und eine Kugel 51 auf eine Ă–ffnung eines ZufĂĽhrkanals 52 fĂĽr eine FlĂĽssigkeit drĂĽckt.At the end remote from the rotation base end of the
Sobald eine Flüssigkeit mit einem hinreichenden Druck in dem Zuführkanal 52 auf die Kugel 51 in Richtung der Düsenöffnung 57 drückt, wird die Kugel 51 gegen die Kraft der Feder 50 aus ihrem Sitz in Richtung des zweiten Leitelementes 44 gedrückt. Hierdurch kann die Flüssigkeit in die Bohrung 49 und in die Speisekanäle 47 fließen. Außerdem erleichtert eine Ausführung mit der Feder 50 die Montage, da sich das Leitelement 44 so bei der Montage selbst positioniert. Über die in dem Gehäuse 39 integrierte erste Ausgleichskammer 53 tritt die Flüssigkeit mittels der Rotationskanäle 54, 55 in die Rotationskammer 56 ein, um schließlich über die Düsenöffnung 57 aus der Düse 38 auszutreten.As soon as a liquid with a sufficient pressure in the

- Als ein Fluid gelangt beispielsweise Wasser mit dem üblichen Druck aus Wasserleitungen durch nicht näher dargestellte Bohrungen eines Druckstückes zu dem ersten Leitelement 10, 32, 43.
13, 14, 35, 54, 55 wird das Wasser von außen her tangential inMittels der Rotationskanäle 25, 37, 56, 65 eingeleitet. Hierbei wird das Wasser von außen auf einer umlaufenden Bahn nach innen und entgegen der Düsenaustrittsöffnung auf diedie Rotationskammer 24, 48 geleitet.Rotationsbasis 24, 48 bildet sich eine rotierende Wasserscheibe, welche sich mit zunehmender Wassermenge in Richtung auf dieAuf der Rotationsbasis 11, 57 als eine rotierende Wassersäule ausbildet. Die Wassermoleküle innerhalb der rotierenden Wassersäule im Bereich der Rotationsachse erreichen eine maximale Rotationsgeschwindigkeit. Hierbei ist der Einfluss des Reibungswiderstandes zwischen der Rotationsbasis 24, 48,Düsenöffnung der Kammerwand 16, der Wand des Kammerraumes 66 und des Kammerkegels 17, 67 einerseits sowie der Wassersäule im Bereich der Rotationsachse andererseits erheblich reduziert. Somit tritt das Wasser mit einer maximalen Rotationsgeschwindigkeit aus der Düsenöffnung 11, 57 aus. Die an 11, 57 frei werdende Zentrifugalkraft führt zu einer kegelförmigen Verteilung eines Sprühnebels mit sehr geringen Tröpfchengrößen. Somit lässt sich auch unter Verwendung eines verhältnismäßig geringen Wasserleitungsdruckes eine sehr feine Vernebelung erreichen.der Düsenöffnung - Dieser sehr feine Nebel kann sowohl zur Klimatisierung in der Tierhaltung als auch zum Ausfiltern von Staub- und/oder Schmutzpartikeln genutzt werden. Des weiteren kann die erfindungsgemäße Düse auch im Bereich des Brandschutzes eingesetzt werden. Hierbei ist im Vergleich zu üblichen Sprinkleranlagen von besonderem Vorteil, dass durch den feinen Sprühnebel nicht nur das Feuer erstickt beziehungsweise gelöscht wird, sondern zugleich Ruß- und Schmutzpartikel aus der Luft ausgefiltert werden. Zudem wird eine Beschädigung von Gegenständen durch einen übermäßigen Flüssigkeitseintrag vermieden. Der Löschwasserschaden kann somit weitgehend vermieden werden.
- As a fluid, for example, water passes with the usual pressure from water pipes through not shown holes of a pressure piece to the
10, 32, 43. By means of thefirst guide element 13, 14, 35, 54, 55, the water is tangentially into therotation channels 25, 37, 56, 65 initiated. In this case, the water is directed from the outside to a circulating path inwards and counter to the nozzle exit opening onto theoutside Rotation chamber 24, 48. On therotation base 24, 48 forms a rotating water disc, which forms with increasing amount of water in the direction of therotation base 11, 57 as a rotating water column. The water molecules within the rotating water column in the area of the axis of rotation reach a maximum rotational speed. Here, the influence of the frictional resistance between thenozzle opening 24, 48, therotation base chamber wall 16, the wall of thechamber space 66 and the 17, 67 on the one hand and the water column in the region of the axis of rotation on the other hand considerably reduced. Thus, the water exits thechamber cone 11, 57 at a maximum rotational speed. The centrifugal force released at thenozzle opening 11, 57 leads to a conical distribution of a spray with very small droplet sizes. Thus, a very fine nebulization can be achieved even using a relatively low water line pressure.nozzle opening - This very fine mist can be used both for air conditioning in animal husbandry and for filtering out dust and / or dirt particles. Furthermore, the nozzle according to the invention can also be used in the field of fire protection. This is compared to conventional sprinkler systems of particular advantage that not only the fire is suffocated or extinguished by the fine spray, but at the same time soot and dirt particles are filtered out of the air. In addition, damage to objects by excessive fluid entry is avoided. The extinguishing water damage can thus be largely avoided.
