Abstract

The invention relates to a jet former (2) disposed in the water outlet (4) of a sanitary outlet fitting (5), and a flow channel (6) having a noncircular clear channel cross-section, the channel longitudinal sides (7, 8) of which are configured longer for forming a flat jet compared to the narrow sides of the channel (9, 10). The jet former (2) according to the invention has a deflection bevel (11) configured as a cross-sectional constriction on one of the two longitudinal sides of the channel (7, 8) thereof, the bevel being aligned with the deflection direction thereof with a wall section of the interior circumferential wall defining the outlet channel (6), wherein the section is provided on the opposite longitudinal side (8) and configured as a rebounding surface (12). A water jet can be formed by means of the jet former (2) according to the invention, the jet following a desired cross-sectional shape predefined by the water outlet (4) across a distance that is as long as possible, without contracting due to the adhesion forces of the water, which would otherwise be optically perceivable in the form of an apparent pivoting motion of the water jet already after only a few centimeters of jet length.

Description

Die Erfindung betrifft einen Strahlformer, der im Wasserauslauf einer sanitären Auslaufarmatur angeordnet ist und einen Durchlasskanal mit einem unrunden lichten Kanalquerschnitt aufweist, dessen Kanal-Längsseiten zur Bildung eines Flachstrahles im Vergleich zu den Kanal-Schmalseiten länger ausgestaltet sind.The invention relates to a jet former, which is arranged in the water outlet of a sanitary outlet fitting and has a passage channel with a non-circular clear channel cross-section, the channel longitudinal sides are designed to be longer to form a flat jet compared to the channel narrow sides.

Im Zuge der immer größer werdenden Bandbreite an Gestaltungsvarianten für Sanitärarmaturen und Sanitärarmaturenausläufe spielen neben den altbekannten runden kreiszylindrischen Wasseraustritten abweichende Formen, wie insbesondere Rechteckquerschnitte mit belüfteten oder unbelüfteten breiten Flachstrahlen, eine immer größere Rolle.In the course of the ever-increasing range of design options for sanitary fittings and Sanitary fittings outlets play in addition to the well-known round circular cylindrical water outlets deviating forms, such as in particular rectangular cross-sections with ventilated or non-ventilated wide flat jets, an increasingly important role.

Ziel der Armaturengestalter ist es dabei, Gestaltungselemente der Sanitärarmatur im Wasserstrahl des austretenden Wassers fortzuführen, das heißt, kantige, quadratische oder rechteckige Geometrieformen der Armatur sollen nach Möglichkeit auch auf den ausfließenden Wasserstrahl übertragen werden, um ein homogenes Gesamterscheinungsbild zu ergeben.The aim of the fitting designer is to continue design elements of the sanitary fitting in the water jet of the exiting water, that is, angular, square or rectangular geometry of the fitting should be transferred to the outflowing water jet, if possible, to give a homogeneous overall appearance.

Dabei besteht jedoch regelmäßig das Problem, dass nicht auf standardisierte und zum großen Teil auch belüftete oder unbelüftete genormte Strahlregler, wie sie beispielsweise in der Europäischen Norm EN 246 beschrieben sind, zurückgegriffen werden kann, wenn aus einem rechteckig gestalteten Armaturenkörper oder Armaturenauslassrohr ein möglichst transparenter Strahl austreten soll, der eine quadratische oder breite, aber flache und zeitlich gesehen stabile Kontur aufweist, das heißt keinen Fluktuationen oder plötzlich schwankenden Strömungsabrissen unterliegt.However, there is regularly the problem that not standardized and largely ventilated or non-ventilated standardized jet regulator, as described for example in the European Standard EN 246, can be used if a rectangular as possible fitting body or Armaturenauslassrohr a transparent as possible beam should emerge, which has a square or wide, but flat and temporally stable contour, that is none Fluctuations or sudden fluctuating stall is subject.

Aus der DE-A-25 52 786 ist bereits eine Vorrichtung bekannt, mittels der das aus einer Brause ausströmende Wasser möglichst geräuscharm in eine Wanne eingelassen werden kann. Die vorbekannte Vorrichtung weist dazu einen an der Wanne anbringbaren Hohlkörper auf, der eine zum Anschließen der Brause bestimmte Frischwassereintrittsöffnung und wenigstens eine an einer Innenwand der Wanne mündende Frischwasseraustrittsöffnung hat. Um die geräuschmindernde Wirkung der vorbekannten Vorrichtung zu begünstigen, und um die durch ihre Frischwasseraustrittsöffnungen durchfließende Wassermenge zu begrenzen, sind im Hohlkörper aus DE-A-25 52 786 vorbekannten Vorrichtung zwischen der Wassereintrittsöffnung und der wenigstens einen Frischwasseraustrittsöffnung Mittel vorgesehen, welche das aus der Brause kommende Wasser verteilen und/oder umlenken sollen, so dass eine rasche Beruhigung und ein glatter Übergang in die laminare Strömung eintreten kann. Solche Verteil- und/oder Umlenkmittel können beispielsweise entsprechend ausgebildete Leitkörper, Leitflächen und/oder Siebe sein, die natürlich keinen so großen Rückstau erzeugen sollten, dass ein solcher Überdruck im Hohlkörper entsteht, in dessen Folge Wasser aus ihm herausspritzen könnte.From the DE-A-25 52 786 A device is already known by means of which the effluent from a shower water can be admitted as quietly as possible in a tub. For this purpose, the known device has a hollow body which can be attached to the tub and which has a fresh water inlet opening intended for connecting the shower and at least one fresh water outlet opening opening on an inner wall of the tub. In order to favor the noise-reducing effect of the prior art device, and to limit the amount of water flowing through their fresh water outlet openings are in the hollow body DE-A-25 52 786 previously known device between the water inlet opening and the at least one fresh water outlet opening provided means which distribute the water coming from the shower and / or divert, so that a rapid reassurance and a smooth transition can occur in the laminar flow. Such distributing and / or deflecting means may be, for example, suitably designed guide bodies, guide surfaces and / or screens which, of course, should not generate such a large backwater that such overpressure arises in the hollow body, as a result of which water could spurt out of it.

Aus der DE 41 08 521 A1 ist eine Strahlbrause mit einem Brausekopf vorbekannt, der zur Bildung eines Brausestrahles eine Vielzahl von Wasseraustrittsöffnungen hat. Der Brausekopf weist eine Strahlbündeleinrichtung mit einer zentralen Wasserdurchtrittsöffnung auf, die an ihrem äußeren Umfangswandbereich in einer ringförmig umlaufenden und taschenförmig ausgestalteten Strömungsumlenkung mündet, in welcher der durchströmende Wasserstrahl zur gegenüberliegenden inneren Mantelfläche des Brausekopf-Gehäuses umgelenkt wird. U. a. auch durch diese, der Strahlbündeleinrichtung nachfolgende Strömungsumlenkung wird in Fließrichtung des Wasserstrahls ein Strömungsrotor ausgebildet, durch den ein direktes Abfließen des Wassers durch die Wasseraustrittsöffnungen vermieden wird. Mit dieser speziellen Strömungsführung wird eine nur sehr geringe Geräuschentwicklung und ein weicher Brausestrahl angestrebt.From the DE 41 08 521 A1 is a jet shower with a shower head previously known, which has a plurality of water outlet openings to form a shower jet. The shower head has a beam bundling device with a central water passage opening, which opens at its outer peripheral wall region in an annular circumferential and pocket-shaped flow deflection, in which the water jet flowing through to the opposite inner The lateral surface of the shower head housing is deflected. U. a. also by this, the beam assembly subsequent flow deflection is formed in the flow direction of the water jet, a flow rotor, through which a direct flow of water through the water outlet openings is avoided. With this special flow control, only a very small amount of noise and a soft shower jet are desired.

Aus der gattungsgemässen DE 203 17 910 U1 ist ein Strahlregler vorbekannt, dessen Gehäuse zur Befestigung innerhalb eines unrunden Auslauf-Innenquerschnitts als entsprechend geformtes, aus zwei gleichen, spiegelbildlich aneinander befestigbaren Kunststoff-Spritzgußteilen gebildet wird. An den inneren, den Durchtrittskanal umgrenzenden Längsseiten dieser Kunststoff-Spritzgußteile ist eine vertikal umlaufende, in den Durchtrittskanal vorstehenden Mittelrippe sowie zwei beidseits der Mittelrippe beabstandet angeordnete Führungsrippen angeformt. Während die vertikal verlaufende Mittelrippe lediglich in ihrem Mittelbereich eine geringfügige Verbreiterung aufweist, sind die Führungsrippen vom Wasseraustritt wegweisend ebenfalls mit drosselartigen Verdickungen versehen, die zum Wasseraustritt hin ebenfalls allmählich auslaufen. Zwischen den vorgenannten Rippen sowie den Innenflächen der Schmalseiten ergeben sich somit vier Strömungsbereiche, die nach dem Zusammenbau der beiden Kunststoff-Spritzgußteile voneinander getrennt sind, da die gegenüberliegenden Rippen dieser Kunststoff-Spritzgußteile jeweils dichtend aufeinander stoßen. Da die zur Mittelrippe gerichteten Flächen der Führungsrippen sowie auch die Innenflächen der Schmalseiten einen zur vertikalen Mittelrippe leicht schräg nach außen gerichteten Verlauf aufweisen, haben auch die vier Strömungsbereiche jeweils tendenziell beim Wasseraustritt einen nach außen gerichteten Verlauf. Dies soll den Vorteil haben, dass der aus den vier Strömungsbereichen gebildete Wasserstrahl nach Austritt aus der wasserführenden Armatur unter Einwirkung des Luftdrucks zwar tendenziell sofort zusammengedrückt wird, jedoch relativ lange die durch den Innenquerschnitt der Auslaufarmatur gebildete Form der einzelnen Strömungsbereiche beibehalten werden kann.From the generic DE 203 17 910 U1 is a jet regulator previously known, the housing is formed for attachment within a non-circular outlet inner cross-section as a correspondingly shaped, of two identical, mirror-image fastened together plastic injection molded parts. At the inner, the passageway bounding longitudinal sides of these plastic injection molded parts is a vertically encircling, in the passage channel projecting central rib and two spaced on both sides of the central rib arranged guide ribs formed. While the vertically extending central rib has only a slight broadening in its central region, the guide ribs are also provided with throttle-like thickenings leading away from the water outlet, which likewise gradually run out towards the water outlet. Between the aforementioned ribs and the inner surfaces of the narrow sides, there are thus four flow areas, which are separated from each other after assembly of the two plastic injection molded parts, since the opposite ribs of these plastic injection molded parts each sealingly abut each other. Since the surfaces of the guide ribs directed towards the center rib and also the inner surfaces of the narrow sides have a course slightly obliquely directed outwards relative to the vertical center rib, the four flow areas also each tend to become trailing when the water exits outward course. This should have the advantage that the water jet formed from the four flow regions tends to be compressed immediately after exiting the water-conducting fitting under the action of the air pressure, but the shape of the individual flow regions formed by the inner cross section of the outlet fitting can be maintained for a relatively long time.

Aus der US-A-2 320 530 ist ein Rohrstück vorbekannt, das in eine sanitäre Wasserleitung zwischengeschaltet werden kann. Das aus US-A-2 320 530 vorbekannte Rohrstück weist einen, entgegen der Durchflussrichtung der Rohrleitung gießkannenartig nach oben vorspringenden Wasserauslauf auf. Im Inneren des Rohrstücks ist eine schuhlöffelartige und am Leitungsinnenumfang verschwenkbar gehaltene Strömungsumlenkung vorgesehen, die in ihrer einen Schwenkstellung den Rohrleitungsquerschnitt der Rohrleitung freihält, um den durchströmenden Wasserstrahl in ihrer anderen Schwenkstellung, der Umlenkstellung, in Richtung zum Wasserauslauf umzulenken. Dabei ist die Auslauföffnung des Wasserauslaufs mit einem Verschlussstück verschließbar, das zum Verschwenken der Strömungsumlenkung mit dieser derart verbunden ist, dass beim Öffnen des Wasserauslaufs sich die Strömungsumlenkung in ihre Umlenkstellung bewegt und der durch die Rohrleitung in den Wasserauslauf umgelenkte Wasserstrahl fontänenartig aus dem Wasserauslauf ausströmen kann.From the US-A-2 320 530 is a piece of pipe previously known, which can be interposed in a sanitary water pipe. The end US-A-2 320 530 Previously known piece of pipe has a, opposite the flow direction of the pipeline watering can-like upwardly projecting water outlet. In the interior of the pipe section a shoehorn-like and pivotally held on the inner circumference flow deflection is provided, which holds in its one pivot position the pipe cross-section of the pipeline to deflect the water jet flowing through in its other pivotal position, the deflection, toward the water outlet. In this case, the outlet opening of the water outlet can be closed with a closure piece, which is connected for pivoting the flow deflection with this, that when opening the water outlet, the flow deflection moves into its deflection and the water jet deflected through the pipe into the water outlet can flow out of the water outlet fountain ,

Es besteht daher insbesondere die Aufgabe, einen Strahlformer der eingangs erwähnten Art zu schaffen, der einen Strahl mit einem unabhängig von den Druckschwankungen des öffentlichen Netzes möglichst gleichen und konstanten Erscheinungsbild zu formen vermag und der mit geringem Aufwand auch in Varianten herstellbar ist, die bezüglich des Wassermengenstroms auf die jeweilig Anwendung - wie beispielsweise Wannenfüllarmatur oder Waschtischarmatur - abgestimmt werden kann. Dabei soll der Wasserstrahl über eine möglichst lange wegstrecke einer gewünschten und durch den Auslass vorgegebenen Querschnittsform folgen, ohne sich durch Adhäsionskräfte des Wassers zusammenzuziehen, was sich andernfalls optisch in einer scheinbaren Drehbewegung des Wasserstrahls, die nach einigen Zentimetern Strahllänge auftritt, bemerkbar macht.It is therefore particularly the task of creating a beam shaper of the type mentioned, which is able to form a beam with an independent of the pressure fluctuations of the public network as equal and constant appearance and which can be produced with little effort in variants that respect Water flow on the respective application - such as tub filler or washbasin faucet - can be adjusted. In this case, the water jet over the longest possible distance of a desired and predetermined by the outlet cross-sectional shape without contracting by adhesive forces of the water, which otherwise makes optically apparent in an apparent rotational movement of the water jet, which occurs after a few centimeters beam length.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den Merkmalen des geltenden Anspruchs 1. Der erfindungsgemäße Strahlformer weist einen Durchlasskanal auf, der an einer seiner beiden Kanal-Längsseiten eine als Querschnittsverengung ausgestaltete Umlenkschräge aufweist, die in einen Teilbereich des Durchlasskanals hineinragt und die in ihrer Umlenkrichtung auf einen an der gegenüberliegenden Längsseite vorgesehenen und als Prallfläche ausgebildeten Wandungsabschnitt der den Durchlasskanal umgrenzenden Innenumfangswandung ausgerichtet ist. Da die Umlenkschräge als Querschnittsverengung ausgestaltet ist, die in einen Teilbereich des Durchlasskanals hineinragt, wird eine Teilmenge des zufließenden Wasserstroms in Richtung des als Prallfläche dienenden gegenüberliegenden Wandungsabschnitts abgelenkt. Durch die Gestaltung dieser Prallfläche, wie beispielsweise deren Neigung, Wölbung und Spreizung sowie deren in Ausströmrichtung orientierte Länge, kann der darauf auftreffende und daran entlanggeführte Wasserstrahl beim Verlassen der sanitären Auslaufarmatur signifikant in seinem Erscheinungsbild beeinflusst werden. Dabei ist von wesentlicher Bedeutung, dass nicht der komplett zulaufende Wasserstrom über die Umlenkschräge zu dem als Prallfläche dienenden Wandungsabschnitt umgelenkt wird, sondern nur eine Teilmenge dieses Wasserstroms, die jedoch dann auch die nicht über die Umlenkschräge geführte Restmenge des Wasserstroms beeinflusst. Das Zusammenwirken von Umlenkschräge einerseits und Prallfläche anderseits und die spezifische Ausrichtung und Abstimmung aufeinander, die eventuell auch in Abhängigkeit der Anströmbedingungen und der Gestaltung des Armaturenkörpers oder Armaturenauslaufs variieren kann, sind entscheidende Faktoren zur Beeinflussung des die Auslaufarmatur verlassenden Wasserstrahls, der die in der Aufgabenstellung geforderten Anforderungen zu erfüllen vermag. Um auf den ausströmenden Wasserstrahl eine strömungsverteilende, gleichrichtende und/oder strämungsberuhigende Wirkung auszuüben und um die Konstanz des von der Prallfläche abströmenden Wasserstrahls zu begünstigen, ist im erfindungsgemäßen Strahlformer dem Durchlasskanal zumindest ein Zulaufgitter oder dergleichen Strömungsgleichrichter in Durchströmrichtung vorgeschaltet.The inventive solution to this problem consists in the features of the current claim 1. The beam former according to the invention has a passage, which has at one of its two channel longitudinal sides designed as a cross-sectional constriction deflection, which projects into a portion of the passage channel and in their direction of deflection a provided on the opposite longitudinal side and designed as a baffle surface wall portion of the passage channel bounding inner peripheral wall is aligned. Since the deflecting bevel is designed as a cross-sectional constriction, which projects into a partial region of the passage channel, a subset of the inflowing water flow is deflected in the direction of the opposite wall portion serving as a baffle surface. Due to the design of this baffle, such as their inclination, curvature and spreading and their oriented in the outflow direction length, the incident on it and water jet along it are significantly influenced in its appearance when leaving the sanitary outlet fitting. It is essential that not the completely tapered water flow is deflected over the deflection bevel to the serving as a baffle wall section, but only a subset of this water flow, but then also affects the not guided over the deflection angle residual amount of water flow. The interaction of deflection on the one hand and baffle on the other hand and the specific alignment and coordination to each other, which may also vary depending on the flow conditions and the design of the fitting body or fitting spout are crucial factors for influencing the water outlet leaving the outlet fitting, which required in the task Is able to meet requirements. In order to exert on the outflowing water jet a flow-distributing, rectifying and / or calming effect and to promote the constancy of the effluent from the impact surface water jet, the passage channel upstream of the passage channel at least one inlet grate or the like flow rectifier in the flow direction.

Um die benötigte Teilmenge bestmöglich in Richtung zu dem als Prallfläche dienenden Wandungsabschnitt umlenken zu können, ist es vorteilhaft, wenn die Umlenkschräge eine in Durchströmrichtung zu ihrem freien, in den Durchlasskanal vorstehenden Längsrand hin gerundete Außenkontur hat.In order to be able to divert the required subset in the best possible direction towards the wall section serving as a baffle surface, it is advantageous if the deflecting bevel has an outer contour rounded in the throughflow direction to its free longitudinal edge protruding into the passage channel.

Dabei sieht eine besonders einfach herstellbare Ausführungsform gemäß der Erfindung vor, dass die Umlenkschräge spanförmig über die Kanal-Längsseite vorsteht. Damit dieses Zulaufgitter oder dergleichen praktisch als Strömungsgleichrichter dienen kann, ist es vorteilhaft, wenn die Gitteröffnungen zumindest eines Zulaufgitter durch in Durchströmrichtung langgezogene Strömungsführungswände umgrenzt sind.In this case, an embodiment which can be produced in a particularly simple manner according to the invention provides that the deflection bevel projects in a chip-shaped manner over the channel longitudinal side. In order for this inlet grid or the like to serve practically as a flow straightener, it is advantageous if the grid openings of at least one inlet grid are bounded by flow guide walls elongated in the flow direction.

Dabei sieht eine Ausführungsform gemäß der Erfindung vor, dass zumindest ein Zulaufgitter etwa in der durch eine der Kanal-längsseiten definierten Ebene angeordnet ist. Bei dieser Ausführungsform wird der durch das Zulaufgitter oder dergleichen durchfließende Wasserstrom in Richtung zum Durchlasskanal umgelenkt, bevor dieser Wasserstrahl im Strahlformer in der gewünschten Weise geformt werden kann. Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass dem Durchströmkanal eine ringförmige Umfangswandung in Durchströmrichtung vorgeschaltet ist, deren beide Wandungs-Längsseiten jeweils als Zulaufgitter ausgestaltet sind. Diese ringförmige Umfangswandung kann am Innenumfang der Auslaufarmatur dicht anliegen, so dass der in Richtung zum Strahlformer fließende Wasserstrom nur durch das an zumindest einer der Wandungs-Längsseiten vorgesehene Zulaufgitter passieren kann.An embodiment according to the invention provides that at least one inlet grid is arranged approximately in the plane defined by one of the channel longitudinal sides. In this embodiment, the water flow passing through the inlet grid or the like is deflected towards the passageway before this water jet can be formed in the beamformer in the desired manner. In this case, a preferred embodiment according to the invention provides that the flow-through channel is preceded by an annular circumferential wall in the direction of flow, the two longitudinal sides of which are configured in each case as an inlet grid. This annular peripheral wall can tightly rest on the inner circumference of the outlet fitting, so that the water flow flowing in the direction of the jet former can only pass through the inlet grid provided on at least one of the longitudinal sides of the wall.

Eine andere Ausführungsform gemäß der Erfindung sieht vor, dass zumindest ein Zulaufgitter in einer etwa quer zur Durchströmrichtung des Durchlasskanals orientierten Ebene angeordnet ist. Ein solches Zulaufgitter kann praktisch die zuströmseitige Stirnöffnung des Durchlasskanals überdecken.Another embodiment according to the invention provides that at least one inlet grid is arranged in a plane oriented approximately transversely to the flow direction of the passage channel. Such a supply grid can practically cover the inflow-side end opening of the passage channel.

Möglich ist, dass der Strahlformer in einem umlenkungsfreien Auslaufendbereich einer sanitären Auslaufarmatur angeordnet ist. Eine bevorzugte Ausführungsform gemäß der Erfindung, die insbesondere auch dem Zeitgeschmack bei der Gestaltung derartiger Auslaufarmaturen entgegenkommt, sieht demgegenüber vor, dass der Strahlformer in der Umlenkzone einer vorzugsweise etwa rechtwinklig orientierten Wasserumlenkung angeordnet ist.It is possible that the jet former is arranged in a deflection-free outlet end region of a sanitary outlet fitting. A preferred embodiment according to the invention, in particular the zeitgeschmack in the design of such Outflow fittings accommodates, on the other hand, that the beam shaper is arranged in the deflection zone of a preferably approximately at right angles oriented water deflection.

Der erfindungsgemäße Strahlformer kann im Wasserauslauf der sanitären Auslaufarmatur beispielsweise mit zumindest einer entsprechenden Befestigungsschraube gehalten sein. Möglich ist aber auch, dass der Strahlformer mittels einer Rastverbindung vorzugsweise lösbar im Wasserauslauf der Auslaufarmatur gehalten ist.The jet former according to the invention can be held in the water outlet of the sanitary outlet fitting, for example with at least one corresponding fastening screw. But it is also possible that the jet former is held by means of a latching connection preferably releasably in the water outlet of the outlet fitting.

Eine bevorzugte Weiterbildung gemäß der Erfindung sieht jedoch vor, dass der Strahlformer reibschlüssig und vorzugsweise lösbar im Wasserauslauf der Auslaufarmatur gehalten ist. Um eine möglichst sichere und feste reibschlüssige Verbindung des Strahlformers im Wasserauslauf zu begünstigen, ist es vorteilhaft, wenn zwischen Strahlformer und Wasserauslauf zumindest ein umlaufender Dichtring vorgesehen ist, der den Strahlformer vorzugsweise im Presssitz im Wasserauslauf hält.However, a preferred embodiment according to the invention provides that the jet former is held by friction and preferably releasably in the water outlet of the outlet fitting. In order to promote the most secure and firm frictional connection of the jet former in the water outlet, it is advantageous if at least one circumferential sealing ring is provided between the jet former and water outlet, which preferably holds the jet former in a press fit in the water outlet.

Die einfache und kostengünstige Herstellung des erfindungsgemäßen Strahlformers wird begünstigt, wenn der Strahlformer als ein- oder mehrteiliges Kunststoffspritzgussteil hergestellt ist.The simple and cost-effective production of the jet former according to the invention is favored when the jet former is produced as a one-part or multi-part plastic injection-molded part.

Eine Weiterbildung gemäß der Erfindung sieht vor, dass der Durchlassquerschnitt des Durchlasskanals in Kanal-Längsrichtung auf der Abströmseite im Vergleich zur Zuströmseite länger ist. Es hat sich überraschend gezeigt, dass der ausströmende Wasserstrahl bei einer solchen weiterbildenden Ausführungsform derart in die Breite auseinander gezogen werden kann, dass dieser Wasserstrahl über eine vergleichsweise große Strahllänge seine Breite beibehält, ohne sich zu einem weitgehend runden Strahl zusammenzuziehen.A development according to the invention provides that the passage cross-section of the passage channel is longer in the channel longitudinal direction on the downstream side compared to the inflow side. It has surprisingly been found that in such a further embodiment, the outflowing water jet can be pulled apart in width such that this water jet retains its width over a comparatively large jet length, without becoming a substantially round jet contract.

Dabei ist es besonders vorteilhaft, wenn die zuströmseitige(n) Eintrittsöffnung(en) des Durchlasskanals an zumindest einem Endbereich in Kanal-Längsrichtung geschlossen ist. Ist der Durchlasskanal an zumindest einem Endbereich in Kanal-Längsrichtung nur an seiner zuströmseitigen Eintrittsöffnung verschlossen, können sich unterhalb des verschlossenen Teilbereiches der Eintrittsöffnung Turbulenzen bilden, die einen seitlichen Unterdruckbereich im Durchlasskanal erzeugen, welcher ein Auseinanderziehen und Verbreitern des ausströmenden Wasserstrahls noch zusätzlich begünstigt.It is particularly advantageous if the inflow-side (s) inlet opening (s) of the passage channel is closed at at least one end region in the channel longitudinal direction. If the passage channel is closed at at least one end region in the channel longitudinal direction only at its inflow-side inlet opening, turbulences can form underneath the closed partial region of the inlet opening, which generate a lateral negative pressure region in the passage channel, which additionally favors the spreading and widening of the outflowing water jet.

Dabei sieht eine besonders einfach herstellbare Ausführungsform gemäß der Erfindung vor, dass das Zulaufgitter an zumindest einem Endbereich in Kanal-Längsrichtung geschlossen ausgestaltet ist.In this case, an embodiment according to the invention that can be produced in a particularly simple manner provides that the inlet grid is designed to be closed at least at one end region in the channel longitudinal direction.

Die einfache Herstellbarkeit des erfindungsgemäßen Strahlformers wird begünstigt, wenn das Zulaufgitter in oder am Strahlformer lösbar befestigbar ist. Ist das Zulaufgitter im oder am Strahlformer lösbar befestigt, wird auch eine modulare Bauweise ermöglicht, so dass ein Strahlformer bei Bedarf mit verschieden ausgestalteten Zulaufgittern kombinierbar ist.The ease of manufacture of the beam former according to the invention is favored when the inlet grid in or on the jet former is releasably fastened. If the inlet grid is detachably fastened in or on the jet former, a modular design is also made possible so that a jet former can be combined, if necessary, with differently configured inlet grilles.

Die einzelnen Merkmale können je für sich oder zu mehreren bei einer Ausführungsform gemäß der Erfindung verwirklicht sein.Further features of the invention will become apparent from the following description of inventive embodiments in conjunction with the claims and the drawings.

In den Figuren 1 bis 12 sind verschiedene Ausführungen 2,3 und 4 eines Strahlformers dargestellt, der einen breiten und über eine lange Wegstrecke stabilen Flachstrahl formen soll. Aus den Figuren 1,3,5 und 7 wird deutlich, dass der Strahlformer 2,3 in dem Wasserauslauf 22 einer hier nur in ihrem auslaufseitigen Endbereich dargestellten sanitären Auslaufarmatur 5 angeordnet ist. Der Strahlformer 2,3 oder 4 weist einen Durchflusskanal 6 mit einem unrunden lichten Kanalquerschnitt auf, dessen Kanal-Längsseiten 7, 8 zur Bildung eines unrunden und breiten Flachstrahles im vergleich zu den Kanal-Schmalseiten 9, 10 länger ausgestaltet sind.In the FIGS. 1 to 12 Different versions 2, 3 and 4 of a beam former are shown which are intended to form a wide flat beam that is stable over a long distance. From the FIGS. 1 . 3 . 5 and 7 It is clear that the jet former 2,3 is arranged in the water outlet 22 of a sanitary outlet fitting 5 shown here only in its outlet end region. The jet former 2, 3 or 4 has a flow channel 6 with a non-circular clear channel cross section on, the channel longitudinal sides 7, 8 are designed to form a non-circular and wide flat jet compared to the channel narrow sides 9, 10 longer.

Dabei ist an der einen der beiden Kanal-Längsseiten 7, 8 - in den Figuren 1,3,7,11 und 12 an der zulaufseitigen Kanal-Längsseite 7 - eine als Querschnittsverengung ausgestaltete Umlenkschräge 11 vorgesehen, die in ihrer Umlenkrichtung auf einen an der gegenüberliegenden Längsseite 8 vorgesehenen und als Prallfläche 12 ausgebildeten Wandungsabschnitt der den Durchflusskanal 6 umgrenzenden Innenumfangswandung ausgerichtet ist.It is on the one of the two channel longitudinal sides 7, 8 - in the FIGS. 1 . 3 . 7 . 11 and 12 on the inlet-side channel longitudinal side 7 - designed as a constriction narrowing bevel 11 is provided, which is aligned in its deflection on a provided on the opposite longitudinal side 8 and formed as a baffle surface 12 wall portion of the flow channel 6 bounding inner peripheral wall.

Der erfindungsgemäße strahlformer 2,3 und 4 weist einen Durchlasskanal 6 auf, der an einer seiner beiden Kanal-Längsseiten eine als Querschnittsverengung ausgestaltete Umlenkschräge 11 aufweist, die in ihrer Umlenkrichtung auf einen, an der gegenüberliegenden Längsseite 8 vorgesehenen und als Prallfläche 12 ausgebildeten Wandungsabschnitt der den Durchlasskanal 6 umgrenzenden Innenumfangswandung ausgerichtet ist. Da die Umlenkschräge 11 als Querschnittsverengung ausgestaltet ist, die in einen Teilbereich des Durchlasskanals 6 hineinragt, wird eine Teilmenge des zufließenden Wasserstroms in Richtung des als Prallfläche 12 dienenden gegenüberliegenden Wandungsabschnitts abgelenkt. Durch die Gestaltung dieser Prallfläche 12, wie beispielsweise deren Neigung, Wölbung und Spreizung sowie deren in Ausströmrichtung orientierte Länge, kann der darauf auftreffende und daran entlanggeführte Wasserstrahl beim Verlassen der sanitären Auslaufarmatur signifikant in seinem Erscheinungsbild beeinflusst werden. Dabei ist von wesentlicher Bedeutung, dass nicht der komplett zulaufende Wasserstrom über die Umlenkschräge 11 zu dem als Prallfläche 12 dienenden Wandungsabschnitt umgelenkt wird, sondern nur eine Teilmenge dieses Wasserstroms, die jedoch dann auch die nicht über die Umlenkschräge 11 geführte Restmenge des Wasserstroms beeinflusst. Das Zusammenwirken von Umlenkschräge 11 einerseits und Prallfläche 12 anderseits und die spezifische Ausrichtung und Abstimmung aufeinander, die eventuell auch in Abhängigkeit der Anströmbedingungen und der Gestaltung des Armaturenkörpers oder Armaturenauslaufs variieren kann, sind entscheidend Faktoren zur Beeinflussung des die Auslaufarmatur 5 verlassenden Wasserstrahls, der die in der Aufgabenstellung geforderten Anforderungen zu erfüllen vermag.The beamformer 2, 3 and 4 according to the invention has a passage channel 6 which has a deflection bevel 11 configured as a cross-sectional constriction on one of its two channel longitudinal sides which, in its deflection direction, is provided on a wall section which is provided on the opposite longitudinal side 8 and designed as a baffle surface 12 is aligned with the passageway 6 bounding inner circumferential wall. Since the deflection bevel 11 is designed as a cross-sectional constriction which projects into a partial region of the passage channel 6, a subset of the inflowing water flow is deflected in the direction of the opposite wall section serving as impact surface 12. Due to the design of this baffle 12, such as its inclination, curvature and spreading and their oriented in the outflow length, the water jet incident on it and along it can be significantly influenced in its appearance when leaving the sanitary outlet fitting. It is essential that not the completely tapered water flow is deflected over the deflection bevel 11 to serving as a baffle 12 wall portion, but only a subset of this flow of water, which, however, then also affects the not guided over the deflection bevel 11 residual amount of water flow. The interaction of deflection bevel 11 on the one hand and baffle 12 on the other hand and the specific alignment and coordination, which may also vary depending on the flow conditions and the design of the fitting body or fitting spout, are crucial factors influencing the outlet valve 5 leaving the water jet, the in fulfills the requirements of the task.

In den Figuren 1,3,5 bis 7, 11 und 12 wird deutlich, dass die hier spanförmig über die Kanal-Längsseite 7 vorstehende Umlenkschräge 11 eine in Durchströmrichtung zu ihrem freien, in den Durchlasskanal 6 vorstehenden Längsrand 13 hin gerundete Außenkontur hat.In the Figures 1,3,5 to 7, 11 and 12 It is clear that the deflecting bevel 11 projecting here in a span shape over the channel longitudinal side 7 has an outer contour rounded in the throughflow direction to its free longitudinal edge 13 protruding into the passage channel 6.

Wie aus den Figuren 1 bis 12 deutlich wird, kann den Strahlformern 2, 3 zumindest ein Zulaufgitter 14, 15 bzw. 23 in Durchströmrichtung vorgeschaltet sein, das auf den vom Strahlformer 2, 3 geformten ausfließenden Wasserstrahl eine vergleichmäßigende, beruhigende und stabilisierende Wirkung hat.Like from the FIGS. 1 to 12 becomes clear, the jet formers 2, 3, at least one inlet grille 14, 15 and 23 may be upstream in the flow direction, which has a uniform, calming and stabilizing effect on the effluent water jet formed by the beam shaper 2, 3.

Bei den in den Figuren 1,2,5 bis 7, 11 und 12 dargestellten Strahlformern 2, 4 ist das Zulaufgitter 14, 23 als separates und in einer etwa quer zur Durchströmrichtung des Durchlasskanals 6 orientierten Ebene angeordnetes Bauteil ausgebildet, das an der zuströmseitigen Stirnöffnung des Strahlformers 2 mittels einer Rastverbindung lösbar gehalten ist.In the in the Figures 1,2,5 to 7, 11 and 12 illustrated jet formers 2, 4, the inlet grid 14, 23 is formed as a separate and arranged in an approximately transversely to the flow direction of the passageway 6 oriented plane component which is releasably held at the inflow-side end opening of the beam former 2 by means of a latching connection.

In den Figuren 3 und 4 ist eine demgegenüber anders ausgestaltete Ausführungsform 3 gezeigt, bei dem dem Durchströmkanal 6 eine ringförmige Umfangswandung 16 in Durchströmrichtung vorgeschaltet ist, deren beide Wandungs-Längsseiten jeweils als Zulaufgitter 15 ausgestaltet sind. Das auch hier strömungsberuhigend wirkende Zulaufgitter 15, das nahezu parallel zu den Kanal-Längsseiten des Strahlformers 3 angeordnet ist, begünstigt die Konstanz des von der Prallfläche 12 abströmenden wasserstroms und zeichnet sich ebenfalls durch eine strömungsverteilende, gleichrichtende und strömungsberuhigende Wirkung aus.In the FIGS. 3 and 4 is a contrast designed differently Embodiment 3 shown, in which the flow channel 6 is preceded by an annular peripheral wall 16 in the flow direction, the two wall longitudinal sides are each configured as a feed grille 15. The inflow grid 15, which also acts to calm the flow and is arranged almost parallel to the channel longitudinal sides of the jet former 3, favors the constancy of the water flow flowing out from the impact surface 12 and is likewise distinguished by a flow-distributing, rectifying and flow-calming effect.

Aus einem Vergleich der Figuren 1,2,5 bis 7, 11 und 12 einerseits und der Figuren 3 und 4 andererseits wird deutlich, dass die Zulaufgitter 14, 15, 23 an den Strahlformer 2, 3 bzw. 4 angeformt oder daran lösbar befestigt sein können; eine hier nicht weiter dargestellte Ausführungsform kann jedoch auch darin bestehen, dass derartige Zulaufgitter, die als Strömungsgleichrichter dienen, separat in Durchströmrichtung vor dem Strahlformer im Armaturenkörper der Auslaufarmatur montiert sein können. Die Zulaufgitter oder dergleichen Strömungsgleichrichter 14, 15, 23 können beispielsweise eine wabenförmige oder - wie hier - eine gitterförmige Wasserführungsstruktur aufweisen.From a comparison of Figures 1,2,5 to 7, 11 and 12 on the one hand and the FIGS. 3 and 4 On the other hand, it is clear that the inlet grille 14, 15, 23 can be formed on the jet former 2, 3 or 4 or detachably secured thereto; However, an embodiment not shown here may also consist in that such inlet grid, which serve as a flow straightener, can be mounted separately in the flow direction before the jet former in the fitting body of the outlet fitting. The inlet gratings or similar flow rectifiers 14, 15, 23 may, for example, have a honeycomb-shaped or, as here, a grid-shaped water-guiding structure.

Die Figuren 1 bis 4 und 7 zeigen den häufigen Einsatzfall, bei welcher der Strahlformer 2 bzw. 3 in der Umlenkzone einer vorzugsweise etwa rechtwinklig orientierten Wasserumlenkung angeordnet ist. Im Bereich dieser Wasserumlenkung wird der durch den Armaturenkörper der Auslaufarmatur 5 geführte Wasserstrom umgelenkt und zu dem etwa beispielsweise rechtwinklig davon angeordneten wasserauslauf 4 geführt. In den Figuren 5 und 6 ist eine demgegenüber abweichend ausgestaltete Variante gezeigt, bei welcher der zulaufende wasserStrom im Bereich des Strahlformers 2 praktisch umlenkungsfrei geführt werden kann und bei welcher der auslaufseitige Endbereich der Auslaufarmatur 5 eine umlenkungsfreie Strömungsführung umgrenzt. In den Figuren 5 und 6 verläuft die durch die Auslaufarmatur 5 zuströmende Wasserführung nahezu parallel zu dem aus dem Strahlformer 2 austretenden Wasserstrahl.The FIGS. 1 to 4 and 7 show the frequent application, in which the beam shaper 2 or 3 is arranged in the deflection zone of a preferably approximately at right angles oriented water deflection. In the area of this water diversion, the water flow guided through the fitting body of the outlet fitting 5 is deflected and guided to the water outlet 4 arranged approximately at right angles, for example. In the FIGS. 5 and 6 On the other hand, a deviating variant is shown in which the incoming water flow can be performed practically free of deflection in the region of the beam former 2 and in which the outlet-side end region of the outlet fitting 5 defines a deflection-free flow guide. In the FIGS. 5 and 6 The inflowing through the outlet fitting 5 water supply runs almost parallel to the emerging from the jet former 2 water jet.

In den Figuren 5 und 6 ist ein mit Figur 1 und 2 vergleichbarer Strahlformer 2 dargestellt.In the FIGS. 5 and 6 is one with FIGS. 1 and 2 comparable beam shaper 2 shown.

Um unabhängig vom wasserdruck des öffentlichen Wassernetzes einen stets optisch gleichen Rechteckflachstrahl zu erhalten, kann es besonders vorteilhaft sein, wenn zuströmseitig - vorzugsweise hinter dem Drosselventil der Armatur - ein Durchflussmengenregler eingebaut ist, der auf die jeweilige Literleistung im konkreten Anwendungsfall abgestimmt ist und diese Literleistung auf einen bestimmten Maximalwert pro Zeiteinheit begrenzt. Durch Variation der Literleistung lässt sich das Strahlbild des Strahlformers ebenfalls in Bezug auf seine Breite, der nutzbaren parallelen Länge, sowie der Geschwindigkeit und der Auftreffgeschwindigkeit im Waschbecken oder auf Gegenständen, die in den Wasserstrahl hineingehalten werden, variieren. Dabei ist es besonders vorteilhaft, wenn die Lage eines solchen druckunabhängigen Durchflussmengenreglers zulaufseitig möglichst weit vom Strahlformer beabstandet ist, um den Wasserstrahl vor Eintritt in den Strahlformer und dessen Auslaufstruktur möglichst optimal zu vergleichmäßigen.In order to obtain a consistently optically equal rectangular flat jet regardless of the water pressure of the public water network, it may be particularly advantageous if a flow regulator is installed on the inflow side - preferably behind the throttle valve of the valve - which is tuned to the respective liter performance in a specific application and this liter performance limits a certain maximum value per unit of time. By varying the liter power, the jet pattern of the jet former can also be varied in terms of its width, the useful parallel length, as well as the speed and impact velocity in the sink or on items held in the water jet. It is particularly advantageous if the position of such a pressure-independent flow rate regulator is as far as possible spaced from the beam former to maximize the water jet before entering the jet former and its outlet structure as optimal as possible.

In den Figuren 1 bis 12 sind die Strahlformer 2, 3 und 4 reibschlüssig und vorzugsweise lösbar im Wasserauslauf 22 der Auslaufarmatur 5 gehalten. Dazu ist in einer am Außenumfang des Strahlformers 2, 3 bzw, 4 vorgesehenen Haltenut 16 ein Dichtring 17 vorgesehen, der den strahlformer 2, 3 bzw. 4 vorzugsweise im Presssitz im Wasserauslauf 4 hält. Zum Lösen des Strahlformers 2, 3 bzw. 4 - beispielsweise aus Reinigungsgründen oder zum Spülen der Auslaufarmatur nach erfolgter Erstinstallation - ist an der der Sichtseite abgewandten Längsseite 7 in dem über den wasserauslauf 4 vorstehenden Wandungsaußenumfang rückseitig eine Vertiefung 16 angebracht. In diese Vertiefung 18 kann die Spitze eines Schraubendrehers eingebracht werden, der durch Abstützen an der Auslaufarmatur 5 zum Heraushebeln des Strahlformers 2, 3 bzw. 4 verwendet werden kann.In the FIGS. 1 to 12 the jet formers 2, 3 and 4 are frictionally and preferably releasably held in the water outlet 22 of the outlet fitting 5. For this purpose, a sealing ring 17 is provided in a provided on the outer circumference of the beam shaper 2, 3, 4, 4 holding groove 16, the jet former 2, 3 and 4, respectively preferably in a press fit in the water outlet 4 holds. To release the beam former 2, 3 or 4 - for example, for cleaning reasons or for flushing the outlet fitting after initial installation - is on the side facing away from the visible side 7 in the over the water outlet 4 protruding Wandungsaußenumfang back a recess 16 is attached. In this recess 18, the tip of a screwdriver can be introduced, which can be used by supporting on the outlet fitting 5 for levering out the beam former 2, 3 and 4 respectively.

Die hier dargestellten Ausführungen 2, 3 und 4 eines Strahlformers zeigen, dass die den Wasserauslauf des Strahlformers 2, 3 bzw. 4 umgrenzenden Ränder scharfkantig ausgestaltet werden können, so dass diese Ränder oder Kanten 19 stets als Abtropfkanten wirken und sich das ausströmende Wasser nicht durch seine Adhäsion zum Strahlformer 2, 3 bzw. 4 an diesem unerwünscht entlang zieht und eventuell über Kapillarwirkungen an die Unterseite der Auslaufarmatur 5 gelangt, um an der Auslaufarmatur 5 entlang weiterzulaufen, was im Laufe der Zeit zu unschönen Verschmutzungen führen kann.The embodiments 2, 3 and 4 of a jet former shown here show that the edges surrounding the water outlet of the jet former 2, 3 and 4 can be made sharp-edged so that these edges or edges 19 always act as dripping edges and the outflowing water does not pass through its adhesion to the beam former 2, 3 or 4 undesirably pulls along this and eventually reaches the underside of the outlet fitting 5 via capillary action in order to continue along the outlet fitting 5, which can lead to unsightly soiling over time.

In Figur 7 ist erkennbar, dass der an der Auslaufarmatur 5 tiefer gelegene Teilbereich der Strahlformer-Umfangswandung mit Überstand über den Wasserauslauf 4 der Auslaufarmatur 5 vorsteht, so dass das Wasser stets an der Unterkante des Strahlformers abtropft und nicht außenseitig an die Auslaufarmatur 5 entlang laufen kann.In FIG. 7 It can be seen that the lower part of the jet former peripheral wall protruding at the outlet fitting 5 protrudes beyond the water outlet 4 of the outlet fitting 5, so that the water always drips off at the lower edge of the jet former and can not run on the outlet fitting 5 on the outside.

Aus einem Vergleich der Figuren 1 bis 12 wird deutlich, dass die hier dargestellten Strahlformer 2, 3 bzw. 4 sowohl als einteiliges als auch als mehrteiliges Kunststoffspritzgussteil hergestellt werden können.From a comparison of FIGS. 1 to 12 It is clear that the jet shaper 2, 3 and 4 shown here can be produced both as a one-piece and as a multi-part plastic injection molded part.

Der in den Fig. 8 bis 12 dargestellte Strahlregler 4 weist ebenfalls einen Durchlasskanal 6 auf, der an einer seiner beiden Kanal-Längsseiten eine als Querschnittsverengung ausgestaltete Umlaufschräge 11 hat, die in ihrer Umlenkrichtung auf einen an der gegenüberliegenden Längsseite 8 vorgesehenen und als Prallfläche 12 ausgebildeten Wandungsabschnitt der den Durchlasskanals 6 umgrenzenden Umfangswandung ausgerichtet ist. Diese hier spanförmig über die Kanal-Längsseite 7 vorstehende Umlenkschräge 11 weist in Durchströmrichtung zu ihrem freien, in den Durchlasskanal 6 vorstehenden Längsrand 13 hin eine gerundete Außenkontur auf. In den Fig. 8 bis 12 ist erkennbar, dass der Durchlassquerschnitt des Durchströmkanals 6 in Kanal-Längsrichtung auf der Abströmseite im Vergleich zur Zuströmseite länger ist. Um dazu die zuströmseitige Eintrittsöffnung des Durchströmkanals 6 an den Endbereichen in Kanal-Längsrichtung geschlossen auszugestalten, weist das Zulaufgitter 23 nur in seinem Mittelbereich eine vielzellige offene Gitterstruktur auf, während das Zulaufgitter 23 demgegenüber an seinen beiden Endbereichen in Kanal-Längsrichtung geschlossen ist. Da der Durchströmkanal an seinen beiden Endbereichen in Kanal-Längsrichtung an der zuströmseitigen Eintrittsöffnung verschlossen ausgestaltet ist, können sich unterhalb des verschlossenen Teilbereiches der Eintrittsöffnung Turbulenzen bilden, die einen seitlichen Unterdruckbereich 21 im Durchströmkanal 6 erzeugen, welcher Unterdruckbereich 21 ein Auseinanderziehen und Verbreitern des ausströmenden Wasserstrahls begünstigt. Bei dem in den Fig. 8 bis 12 gezeigten Strahlregler 4 wird der ausströmende Wasserstrahl sogar über die Längserstreckung des abströmseitigen lichten Öffnungsquerschnitts des Strahlformers 4 derart in die Breite auseinander gezogen, dass dieser Wasserstrahl über eine vergleichsweise große Strahllänge seine Breite beibehält, ohne sich zu einem weitgehend runden Strahl wieder zusammenzuziehen. Auf diese Weise kann ein breites und dennoch flaches Strahlbild erzeugt werden, wobei der aus dem Strahlformer 4 ausströmende Strahl im Vergleich zu den Strahlformern 2 bzw. 3, bei denen der Durchströmkanal 6 einen im wesentlichen gleich bleibenden Durchlassquerschnitt hat, auch über eine größere Strahllänge wesentlich breiter ausströmt.The in the 8 to 12 illustrated jet regulator 4 also has a passage channel 6 which has on one of its two channel longitudinal sides designed as a cross-sectional constriction 11 which in its deflection to a provided on the opposite longitudinal side 8 and formed as a baffle surface 12 wall portion of the passage channel 6 bounding peripheral wall is aligned. This deflecting bevel 11 projecting here in a span shape over the channel longitudinal side 7 has a rounded outer contour in the direction of flow to its free longitudinal edge 13 protruding into the passage channel 6. In the 8 to 12 It can be seen that the passage cross-section of the flow channel 6 in the channel longitudinal direction on the downstream side is longer compared to the inflow side. In order to design the inflow-side inlet opening of the flow channel 6 closed at the end regions in the channel longitudinal direction, the inlet lattice 23 has a multicellular open lattice structure only in its middle region, while the inlet lattice 23 is closed at its two end regions in the channel longitudinal direction. Since the flow-through channel is configured to be closed at its two end regions in the channel longitudinal direction at the inflow-side inlet opening, turbulences can form underneath the closed partial region of the inlet opening which produce a lateral negative pressure region 21 in the flow-through channel 6, which negative-pressure region 21 is a spreading and widening of the outflowing water jet favored. In the in the 8 to 12 shown jet stream 4, the outflowing water jet is pulled apart even over the longitudinal extent of the downstream clear opening cross-section of the beam former 4 in the width that this water jet over a comparatively long beam length its Width maintains, without contracting to a largely round beam again. In this way, a broad, yet flat jet pattern can be generated, wherein the effluent from the beam former 4 beam compared to the beam formers 2 and 3, in which the flow channel 6 has a substantially constant passage cross-section, even over a larger beam length substantially flows out wider.
