Description

Die Erfindung betrifft einen Strahlregler mit zumindest einem Strahlzerleger, der den zuströmenden Wasserstrom aufteilt, mit einem hülsenförmigen Innengehäuse, dass von einem Außengehäuse umhüllt ist, und mit wenigstens einem zwischen Innengehäuse und Außengehäuse angeordneten Belüftungskanal, der mindestens eine Einlauföffnung und wenigstens eine, am Gehäuseumfang des Innengehäuses vorgesehene Durchtrittsöffnung hat.The invention relates to a jet regulator with at least one jet splitter, which divides the inflowing water flow, with a sleeve-shaped inner housing that is encased by an outer housing, and with at least one ventilation channel arranged between the inner housing and the outer housing, which has at least one inlet opening and at least one, on the housing circumference of the Has inner housing provided passage opening.

Aus der WO 2012/055 051 A1 ist bereits eine Vorrichtung zum Versprühen einer unter Druck stehenden Flüssigkeit vorbekannt, die als Mundstück einer sanitären Auslaufarmatur oder als Duschkopf dienen kann. Die vorbekannte Vorrichtung weist einen zentralen Zuführungskanal für die Flüssigkeit auf, der entlang der Vorrichtungsachse verläuft. Mit Abstand um die Vorrichtungsachse herum sind mehrere Wirbelkammern vorgesehen, die jeweils einen Einlass zur Zuführung der Flüssigkeit in die jeweilige Wirbelkammer sowie eine Auslassdüse zum Austritt eines Flüssigkeitsstrahles aus der Wirbelkammer aufweisen. Die Wirbelkammern sind mit dem Zuführungskanal über Einlaufkanäle verbunden, die im Wesentlichen quer zur Vorrichtungsachse angeordnet sind. Jede der Auslassdüsen ist derart schräg zur Vorrichtungslängsachse angeordnet, dass aus den Auslassdüsen austretende Flüssigkeitsstrahlen in einem vorbestimmten Abstand von den Auslassdüsen aufeinander treffen. Das Strahlbild des aus der vorbekannten Vorrichtung austretenden Wasserstrahls ist jedoch noch verbesserungswürdig.From the WO 2012/055 051 A1 a device for spraying a liquid under pressure is already known, which can serve as a mouthpiece of a sanitary outlet fitting or as a shower head. The previously known device has a central supply channel for the liquid, which runs along the axis of the device. A plurality of turbulence chambers are provided at a distance around the device axis, each of which has an inlet for feeding the liquid into the respective turbulence chamber and an outlet nozzle for exiting a jet of liquid from the turbulence chamber. The vortex chambers are connected to the feed duct via inlet ducts which are arranged essentially transversely to the device axis. Each of the outlet nozzles is arranged obliquely to the longitudinal axis of the device in such a way that liquid jets emerging from the outlet nozzles meet at a predetermined distance from the outlet nozzles. However, the jet pattern of the water jet emerging from the previously known device is still in need of improvement.

Man hat daher auch eine Zerstäuberdüse geschaffen, die ebenfalls am Wasserauslauf einer sanitären Auslaufarmatur montierbar ist, um das unter Druck zuströmende Wasser zu zerstäuben und dadurch zu einem homogenen Wasserstrahl zu formen (vgl. DE 20 2013 002 283 U1 ). Die vorbekannte Zerstäuberdüse weist eine Drallkammer auf, in der zumindest ein quer zur Düsen-Längsachse orientierter und derart tangential in die Drallkammer einlaufender Zuführkanal mündet, dass das in der Drallkammer einströmende Wasser einen Drall um die Drallkammer-Längsachse erfährt. Die Drallkammer verjüngt sich in Abströmrichtung in Richtung zu einem Düsenkanal, so dass der in der Drallkammer in Rotation um die Drallkammer-Längsachse versetzte Wasserstrahl in immer kleineren Kreisbahnen zusammengeführt und durch den Düsenkanal geleitet wird, bis der Wasserstrahl an dem Kanalendbereich des Düsenkanals in die Atmosphäre austritt, wo sich eine Fluid-Lamelle ausbildet, die an ihrem freien Umfangsrandbereich in derart feine Einzeltröpfchen zerplatzt, dass ein homogener und aus feinen Wassertröpfchen gebildeter Wasserstrahl entsteht.An atomizer nozzle has therefore also been created which can also be mounted on the water outlet of a sanitary outlet fitting in order to atomize the water flowing in under pressure and thereby shape it into a homogeneous water jet (cf. DE 20 2013 002 283 U1 ). The previously known atomizer nozzle has a swirl chamber in which at least one orientated transversely to the longitudinal axis of the nozzle and entering the swirl chamber tangentially in such a way that the water flowing into the swirl chamber experiences a swirl about the longitudinal axis of the swirl chamber. The swirl chamber tapers in the outflow direction in the direction of a nozzle channel, so that the water jet, which is rotated in the swirl chamber about the longitudinal axis of the swirl chamber, is brought together in ever smaller circular paths and guided through the nozzle channel until the water jet is released into the atmosphere at the end area of the nozzle channel exits, where a fluid lamella forms, which bursts into such fine individual droplets at its free peripheral edge area that a homogeneous water jet formed from fine water droplets is produced.

Mit Hilfe der vorbekannten und als Zerstäuberdüse ausgebildeten Strahlregler lässt sich das aus dem Wasserauslauf ausströmende Wasser jedoch nicht ohne weiteres mit der Umgebungsluft derart vermischen, dass auch bei einer geringen Durchflussleistung noch ein homogener, perlend-weicher und gut durchmischter Wasserstrahl gebildet wird.However, with the aid of the previously known aerator designed as an atomizer nozzle, the water flowing out of the water outlet cannot easily be mixed with the ambient air in such a way that even with a low flow rate, a homogeneous, sparkling-soft and well-mixed water jet is formed.

Aus der DE 10 2006 013 881 A1 ist ein Spar-Duschkopf vorbekannt, der unter Zuhilfenahme von Wasserwirbeln in Verbindung mit der durch den Wirbel angesaugten Umgebungsluft ein Wasser-/Luftgemisch bildet. Der vorbekannte Spar-Duschkopf weist dazu ein Gehäuse mit einem zentral angeordneten Lufteinlass auf, den eine konzentrisch, konisch oder hyperbolisch ausgeformte Wasserauslassblende mit Löchern umgibt. Der vorbekannte Spar-Duschkopf ist über ein Zulaufrohr mit einer unter Druck stehenden Wasserleitung verbunden. In diesem Zulaufrohr ist eine Steuerblende vorgesehen, die das zuströmende Wasser zu einem auf den Kopf gestellten hyperbolischen Wasserwirbel formt. Dieser Wasserwirbel erzeugt im Gehäuse des vorbekannten Spar-Duschkopfes einen Unterdruck, der ein Ansaugen von Umgebungsluft über den zentralen Lufteinlass in das Gehäuse bewirkt. Diese Luft wird dem durch das Gehäuse durchströmenden Wasser durch die Wasserauslassblende zugeführt. Das mit Umgebungsluft durchmischte Wasser verlässt den vorbekannten Spar-Duschkopf über die Löcher in der Wasserauslassblende in Form von kurzen strichartigen Wassergebilden, die mit Luftzwischenräumen gefüllt sind. In Folge dieser besonderen Formgebung des ausströmenden Wasser-/Luft-Gemisches entsteht für den Anwender das Gefühl, sich unter einem ununterbrochenen Wasserstrahl zu befinden. Ein homogener und perlend-weicher Auslaufstrahl lässt sich in dem vorbekannten Spar-Duschkopf jedoch nicht formen.From the DE 10 2006 013 881 A1 an economy shower head is already known, which forms a water/air mixture with the aid of water vortices in connection with the ambient air sucked in by the vortex. For this purpose, the previously known economy shower head has a housing with a centrally arranged air inlet, which is surrounded by a concentrically, conically or hyperbolically shaped water outlet screen with holes. The previously known economy shower head is connected to a pressurized water line via an inlet pipe. A control orifice is provided in this inlet pipe, which forms the inflowing water into an upside-down hyperbolic water vortex. This water vortex generates a negative pressure in the housing of the previously known savings shower head, which causes ambient air to be sucked in via the central Air intake causes in the housing. This air is supplied to the water flowing through the housing through the water outlet panel. The water mixed with ambient air leaves the previously known economy shower head through the holes in the water outlet panel in the form of short, line-like water formations that are filled with air gaps. As a result of this special shape of the outflowing water/air mixture, the user gets the feeling of being under a continuous jet of water. However, a homogeneous and sparkling-soft discharge jet cannot be formed in the previously known economy shower head.

Aus der EP 0 429 068 A1 ist eine Sprudelwasser-Auslassvorrichtung bekannt, die an einem Ende eines Auslaufs eines Wasserhahns, Duschkopfs oder dergleichen angebracht ist, um Blasen in dem Wasserfluss zu erzeugen.From the EP 0 429 068 A1 a sparkling water outlet device is known which is installed at an end of a spout of a faucet, Shower head or the like is attached to create bubbles in the water flow.

Es besteht daher die Aufgabe, einen Strahlregler der eingangs erwähnten Art zu schaffen, der sich auch bei möglichst geringen Durchflussleistungen durch eine gute Zerlegung des zuströmdenden Wassers und durch eine optimierte Vermischung des zerlegten Wassers mit der Umgebungsluft auszeichnet, sodass in diesem Strahlregler ein homogener, perlend-weicher und gut durchmischter Auslaufstrahl gebildet wird.There is therefore the task of creating an aerator of the type mentioned at the outset, which is characterized by good decomposition of the inflowing water and optimized mixing of the decomposed water with the ambient air, even with the lowest possible flow rates, so that in this aerator a homogeneous, sparkling -a soft and well-mixed outlet jet is formed.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere in den Merkmalen des Patentanspruchs 1.The inventive solution to this problem consists in the aerator of the type mentioned in particular in the features of claim 1.

Der erfindungsgemäße Strahlregler, der am Wasserauslauf einer sanitären Auslaufarmatur montierbar ist, weist zumindest einen Strahlzerleger auf, der den zuströmenden Wasserstrahl aufteilt und in kleine Wasserteilchen oder Wasserstrahlen zerlegt. Der erfindungsgemäße Strahlregler hat dazu ein hülsenförmiges Innengehäuse, das von einem Außengehäuse umhüllt ist. Dabei ist zwischen dem Innengehäuse, das einen wasserführenden Leitungsabschnitt bildet, und dem Außengehäuse zumindest ein Belüftungskanal angeordnet, durch den die zum Durchmischen mit (es folgen die ursprünglichen Seiten 4 bis 17) dem das Innengehäuse durchströmenden Wasser bestimmte Umgebungsluft angesaugt werden kann. Der zumindest eine Belüftungskanal hat eine Einlauföffnung und wenigstens eine Durchtrittsöffnung, die am Gehäuseumfang des Innengehäuses vorgesehen ist und durch welche die vom Belüftungskanal kommende Umgebungsluft in den Gehäuseinnenraum des Innengehäuses einströmen kann. Der zumindest eine Strahlzerleger des erfindungsgemäßen Strahlreglers ist als Strahlzerstäuberdüse ausgebildet, die den zuströmenden Wasserstrom in einen Spray aus feinen Tröpfchen (Nebel) zerstäubt und ein Aerosol aus mit Umgebungsluft vermischten feinen Tröpfchen erzeugt, das im Innengehäuse einen hohlkegelförmigen Strahl aus separierten Flüssigkeitsanteilen bildet. Dabei zeichnet sich die als Strahlzerleger dienende Zerstäuberdüse auch bei einer vergleichsweise geringen Durchflussleistung noch durch eine gute Strahlaufteilung und - zerlegung aus. In Strömungsrichtung unterhalb der mindestens einen Durchtritts-öffnung ist am Innenumfang des Innengehäuses eine ringförmig umlaufende Auftreffzone angeordnet, in welcher der hohlkegelförmig aufgeteilte Wasserstrahl am Gehäuseinnenumfang des Innengehäuses auftritt. Der Gehäuseinnenraum des Innengehäuses dient dabei als Mischkammer, in welcher der hohlkegelförmig aufgeteilte Wasserstrahl mit der von der wenigstens einen Durchtrittsöffnung kommenden Umgebungsluft noch zusätzlich durchmischt wird, bevor der luftdurchmischte Wasserstrahl in Strömungsrichtung nach der Aufprallzone wieder zu einem perlend-weichen Auslaufstrahl mit homogenem, zylindrischen Strahlaußenumfang geformt wird. Die aus der Zerstäuberdüse noch als feiner Nebel austretenden Wassertröpfchen, die mit Keimen belastet sein und beim Einatmen ein Gesundheitsrisiko beinhalten können, werden im Innengehäuse in Strömungsrichtung unterhalb der Aufprallzone somit zu einem homogenen und insoweit gesundheitlich unbedenklichen Strahl geformt.The aerator according to the invention, which can be mounted on the water outlet of a sanitary outlet fitting, has at least one jet splitter, which splits the inflowing water jet and breaks it up into small water particles or water jets. For this purpose, the jet regulator according to the invention has a sleeve-shaped inner housing which is surrounded by an outer housing. At least one ventilation channel is arranged between the inner housing, which forms a water-carrying line section, and the outer housing, through which the for mixing with (the original pages 4 to 17 follow) the water flowing through the inner housing certain ambient air can be sucked. The at least one ventilation duct has an inlet opening and at least one passage opening, which is provided on the housing circumference of the inner housing and through which the ambient air coming from the ventilation duct can flow into the housing interior of the inner housing. The at least one jet splitter of the jet regulator according to the invention is designed as a jet atomizer nozzle, which atomizes the inflowing water flow into a spray of fine droplets (mist) and generates an aerosol of fine droplets mixed with ambient air, which forms a hollow cone-shaped jet of separated liquid components in the inner housing. In this case, the atomizer nozzle serving as a jet splitter is still characterized by good jet splitting and splitting, even with a comparatively low flow rate. In the direction of flow below the at least one through-opening, a ring-shaped circumferential impingement zone is arranged on the inner circumference of the inner housing, in which zone the water jet, divided in the shape of a hollow cone, occurs on the inner circumference of the inner housing. The interior of the inner housing serves as a mixing chamber, in which the water jet, which is divided into a hollow cone, is additionally mixed with the ambient air coming from the at least one passage opening, before the air-mixed water jet in the direction of flow after the impact zone again becomes a soft, sparkling discharge jet with a homogeneous, cylindrical jet outer circumference is formed. The water droplets emerging from the atomizer nozzle as a fine mist, which are contaminated with germs and can pose a health risk when inhaled, are thus formed into a homogeneous and harmless jet in the inner housing in the flow direction below the impact zone.

Um die Umgebungsluft gleichmäßig der im Gehäuseinnenraum des Innengehäuses vorgesehenen Mischkammer zuführen zu können, ist es vorteilhaft, wenn der Belüftungskanal als ein zwischen Innengehäuse und Außengehäuse angeordneter Ringspalt ausgebildet ist.In order to be able to supply the ambient air uniformly to the mixing chamber provided in the housing interior of the inner housing, it is advantageous if the ventilation channel is designed as an annular gap arranged between the inner housing and the outer housing.

Eine bevorzugte Weiterbildung gemäß der Erfindung sieht vor, dass in dem wenigstens einen Belüftungskanal mindestens eine Querschnittsverengung ausgebildet ist.

Zu diesem Zweck sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass das Innengehäuse sich zu seiner Auslaufstirnseite hin vorzugsweise stufenweise verjüngt oder verengt. Diese am Gehäuseinnenumfang des Innengehäuses vorgesehene wenigstens eine Stufe kann um den Gehäuseinnenumfang umlaufen oder auch segmentiert oder unterbrochen sein. Als die Durchmischung von Wasser und Umgebungsluft begünstigende Strömungshindernisse sind auch andere Vorsprünge denkbar, die vom Gehäuseinnenumfang des Innengehäuses aus in dessen Gehäuseinnenraum vorstehen.In order to further promote good mixing of the water flowing through with the ambient air, it is advantageous if at least one flow obstacle is provided in the inner housing. For this purpose, a preferred embodiment according to the invention provides that the inner housing preferably tapers or narrows in steps towards its outlet end face.

Dieser, am Auslaufende des Innengehäuses vorgesehene Strömungsgleichrichter formt aus dem im Gehäuseinneren des Innengehäuses mit Umgebungsluft durchmischten verwirbelten Wasser einen homogenen Auslaufstrahl.In order to promote the formation of a homogeneous outlet jet, it is advantageous if a flow straightener is provided on the outlet end face of the inner housing, which has a lattice, mesh or honeycomb structure with flow-guiding through-holes. This flow straightener, which is provided at the outlet end of the inner housing, forms a homogeneous outlet jet from the turbulent water mixed with ambient air inside the inner housing.

Um die Gleichrichtung des auslaufenden Wassers im Strömungsgleichrichter zu begünstigen, ist es vorteilhaft, wenn zumindest die Mehrzahl der Durchflusslöcher eine Längserstreckung in Durchflussrichtung haben, die im Vergleich zur maximalen Weite der Durchflusslöcher größer ist.In order to promote the straightening of the outflowing water in the flow straightener, it is advantageous if at least the majority of the flow holes have a longitudinal extension in the direction of flow that is greater than the maximum width of the flow holes.

Um ein Anheben des Strömungsgleichrichters in den als Mischkammer dienenden Gehäuseinnenraum des Innengehäuses zu verhindern und um funktionsbeeinträchtigenden Manipulationen am Strömungsgleichrichter entgegenzuwirken, ist es vorteilhaft, wenn der Strömungsgleichrichter an das Innengehäuse innenumfangsseitig angeformt ist.In order to prevent the flow straightener from being lifted up into the housing interior of the inner housing serving as a mixing chamber and to counteract manipulation of the flow straightener that would impair its function, it is advantageous if the flow straightener is molded onto the inner circumference of the inner housing.

Eine gute Strahlformung des austretenden Wassers wird begünstigt, wenn dem Strömungsgleichrichter wenigstens eine Lochplatte in Strömungsrichtung vorgeschaltet ist.Good jet formation of the exiting water is promoted if at least one perforated plate is connected upstream of the flow straightener in the direction of flow.

Dabei wird eine Ausführungsform bevorzugt, bei der die wenigstens eine Lochplatte Löcher hat, deren maximale Weite im Vergleich zur Weite der Durchflusslöcher des Strömungsgleichrichters kleiner ist.An embodiment is preferred in which the at least one perforated plate has holes whose maximum width is Compared to the width of the flow straightener flow holes is smaller.

Eine einfache und zweckmäßige Ausführung gemäß der Erfindung sieht vor, dass die wenigstens eine Lochplatte in den Gehäuseinnenraum des Innengehäuses eingesetzt und vorzugsweise auf den Strömungsgleichrichter aufgelegt ist.A simple and expedient embodiment according to the invention provides that the at least one perforated plate is inserted into the housing interior of the inner housing and is preferably placed on the flow straightener.

Um den erfindungsgemäßen Strahlregler am Wasserauslauf einer sanitären Auslaufarmatur montieren zu können, ist es vorteilhaft, wenn das Außengehäuse an seinem zuströmseitigen Gehäuseumfang eine Kupplung aufweist, die mit einer Gegenkupplung am Wasserauslauf der sanitären Auslaufarmatur zusammenwirkt. Dabei kann eine besonders einfache und vorteilhafte Ausführungsform gemäß der Erfindung darin bestehen, dass die am Außengehäuse vorgesehene Kupplung als Gewinde ausgebildet ist, das mit einem Gegengewinde am Wasserauslauf der sanitären Auslaufarmatur zusammenwirkt.In order to be able to mount the aerator according to the invention on the water outlet of a sanitary outlet fitting, it is advantageous if the outer housing has a coupling on its inflow-side housing circumference which interacts with a counter-coupling on the water outlet of the sanitary outlet fitting. A particularly simple and advantageous embodiment according to the invention can consist in the coupling provided on the outer housing being designed as a thread which interacts with a counter-thread on the water outlet of the sanitary outlet fitting.

Die Konstruktion und Herstellung des erfindungsgemäßen Strahlreglers wird wesentlich vereinfacht, wenn das Innengehäuse außenumfangsseitig zumindest einen Einsetzanschlag hat, und wenn das Innengehäuse in das Außengehäuse einsetzbar ist, bis der Einsetzanschlag auf einem am Gehäuseinnenumfang des Außengehäuses vorgesehen Auflager aufliegt.The design and manufacture of the jet regulator according to the invention is significantly simplified if the inner housing has at least one insertion stop on the outer circumference and if the inner housing can be inserted into the outer housing until the insertion stop rests on a support provided on the inner circumference of the outer housing.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass der Einsetzanschlag als segmentierter oder umlaufender Ringabsatz ausgebildet ist.A preferred embodiment according to the invention provides that the insertion stop is designed as a segmented or circumferential ring shoulder.

Die positionsgenaue Anordnung der aus Strahlzerlger und Innengehäuse gebildeten Einheit im Außengehäuse des erfindungsgemäßen Strahlreglers wird begünstigt, wenn die zulaufseitige Stirnfläche des als Querschnittsverengung dienenden Ringflansch als Auflager für den zumindest einen Einsetzanschlag dient.The exact positioning of the unit formed by the jet splitter and the inner housing in the outer housing of the jet regulator according to the invention is favored if the inlet-side end face of the cross-sectional constriction serving annular flange serves as a support for the at least one insertion stop.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht zu diesem Zweck auch vor, dass der ablaufseitige Stirnrandbereich des Außengehäuses in Richtung zum Innengehäuses und/oder des Innengehäuse in Richtung zum Außengehäuse abgewinkelt ist. Somit weist die Einlauföffnung im Vergleich zum lichten Kanalquerschnitt des Belüftungskanals in dem in Strömungsrichtung nachfolgenden Kanalabschnitt einen reduzierten Querschnitt auf, wodurch der Austritt der im Belüftungskanal reflektierten Störgeräusche noch zusätzlich erschwert und ein geräuscharmer Betrieb des erfindungsgemäßen Strahlreglers noch zusätzlich begünstigt wird.In order to additionally prevent the emergence of such disturbing noises, which are generated in the jet regulator according to the invention by the water flowing through, it is advantageous if the inlet opening of the at least one ventilation channel is provided on the outlet side of the jet regulator.

The inlet opening therefore has a reduced cross-section compared to the clear channel cross-section of the ventilation channel in the downstream channel section in the flow direction, which makes it even more difficult for the noise reflected in the ventilation channel to escape and low-noise operation of the jet regulator according to the invention is additionally promoted.

Eine bevorzugte Weiterbildung gemäß der Erfindung sieht vor, dass der Strahlregler einen einzigen, vorzugsweise zentralen Strahlzerleger hat und wenn die Längsachsen von Strahlzerleger, Innengehäuse und Außengehäuse koaxial zueinander angeordnet sind.A preferred development according to the invention provides that the jet regulator has a single, preferably central jet splitter and when the longitudinal axes of the jet splitter, inner housing and outer housing are arranged coaxially to one another.

Die Montage des erfindungsgemäßen Strahlreglers wird wesentlich vereinfacht und der Zusammenhalt der den erfindungsgemäßen Strahlregler bildenden Bestandteile während der Lagerung und des Transports wird begünstigt, wenn der Strahlzerleger auf der zulaufseitigen Stirnseite des Innengehäuses mit diesem verbindbar und vorzugsweise lösbar verrastbar ist.The assembly of the jet regulator according to the invention is significantly simplified and the cohesion of the components forming the jet regulator according to the invention during storage and transport is promoted if the jet splitter can be connected to the inner housing on the inlet-side end face of the latter and preferably latched in a detachable manner.

In den Fig. 1 bis 6 sind ein Strahlregler 1 (vgl. Fig. 5) und dessen wesentlichen Bestandteile in verschiedenen Darstellungen gezeigt. Der Strahlregler 1 soll sich auch bei möglichst geringen Durchflussleistungen durch eine gute Zerlegung des zuströmenden Wassers und durch eine optimierte Vermischung des zerlegten Wassers mit der Umgebungsluft auszeichnen, so dass in diesem Strahlregler 1 ein homogener, perlend-weicher und gut durchmischter Auslaufstrahl gebildet wird. Der hier dargestellte Strahlregler 1 ist dazu am Wasserauslauf einer hier nicht weiter gezeigten sanitären Auslaufarmatur montierbar. Der Strahlregler 1 weist dazu einen Strahlzerleger 2 auf, der den zuströmenden Wasserstrom aufteilt und in kleine Wasserteilchen oder Wasserstrahlen zerlegt. Der Strahlregler 1 hat ein hülsenförmiges Innengehäuse 3, das von einem Außengehäuse 4 umhüllt ist. Dabei ist zwischen dem Innengehäuse 3, das einen wasserführenden Leitungsabschnitt bildet, und dem Außengehäuse 4 zumindest ein Belüftungskanal 5 angeordnet, durch den die zum Durchmischen mit dem das Innengehäuse 3 durchströmenden Wasser bestimmte Umgebungsluft angesaugt werden kann.In the Figures 1 to 6 are an aerator 1 (cf. figure 5 ) and its essential components are shown in different representations. The aerator 1 should also be characterized by a good separation of the inflowing water and an optimized mixing of the separated water with the ambient air, even with the lowest possible flow rates, so that a homogeneous, sparkling-soft and well-mixed outlet jet is formed in this aerator 1. The jet regulator 1 shown here can be mounted on the water outlet of a sanitary outlet fitting that is not shown here. For this purpose, the aerator 1 has a jet splitter 2, which divides the inflowing water flow and breaks it up into small water particles or water jets. The aerator 1 has a sleeve-shaped inner housing 3 which is surrounded by an outer housing 4 . In this case, at least one ventilation channel 5 is arranged between the inner housing 3, which forms a water-carrying line section, and the outer housing 4, through which the certain ambient air can be sucked in for mixing with the water flowing through the inner housing 3 .

Der zumindest eine Belüftungskanal 5 hat wenigstens eine Einlauföffnung 6 und mindestens eine Durchtrittsöffnung 7, die am Gehäuseumfang des Innengehäuses 3 vorgesehen ist, und durch welche die vom Belüftungskanal 5 kommende Umgebungsluft in den als Mischkammer dienenden Gehäuseinnenraum des Innengehäuses 3 einströmen kann.The at least one ventilation duct 5 has at least one inlet opening 6 and at least one passage opening 7, which is provided on the housing circumference of the inner housing 3 and through which the ambient air coming from the ventilation duct 5 can flow into the housing interior of the inner housing 3, which serves as a mixing chamber.

Der zumindest eine Strahlzerleger 2 des Strahlreglers 1 ist als Zerstäuberdüse ausgebildet, die den zuströmenden Wasserstrom in einen im Wesentlichen hohlkegelförmigen Wasserstrahl aufteilt und die sich auch bei einer vergleichsweise geringen Durchflussleistung noch durch eine gute Strahlaufteilung und -zerlegung auszeichnet. Die als Strahlzerleger 2 dienende Zerstäuberdüse hat einen Düsenkorpus 8, der am zulaufseitigen Stirnrand des Innengehäuses 3 mit diesem verbindbar und vorzugsweise verrastbar ist. Im Düsenkorpus 8 ist eine Drallkammer 9 vorgesehen, die zuströmseitig einen im lichten Querschnitt im Wesentlichen zylindrischen oder scheibenförmigen Kammerabschnitt 10 hat. In der Drallkammer 9 mündet zumindest ein quer und vorzugsweise rechtwinklig zur Düsen-Längsachse orientierter und tangential in die Drallkammer 2 einlaufender Zuführkanal 11. In der Drallkammer 2 münden dazu mehrere, durch jeweils eine Nut 29 gebildete Zuführkanäle 11, die in Umfangsrichtung gleichmäßig voneinander beabstandet sind. Die Drallkammer 9 verjüngt sich in Abströmrichtung trichterförmig in Richtung zu einem Düsenkanal 12. Der trichterförmige Abschnitt der Drallkammer 9 ist in seinem lichten Querschnitt so ausgestaltet, dass die Drallkammer 9 in Richtung zum Düsenkanal 5 die Form eines kegeligen oder rotationshyperbolischen Trichters aufweist. Die als Strahlzerleger 2 dienende Zerstäuberdüse weist in ihrem Düsenkorpus 8 eine zuströmseitige Einsetzöffnung 13 auf. An der Umfangswand dieser Einsetzöffnung 13 ist wenigstens eine, zur Bildung eines Einlaufkanales 30 bestimmte Nut 14 vorgesehen. Dabei ist jedem Zuführkanal 11 jeweils ein in Düsen-Längsrichtung orientierter Einlaufkanal 30 in Strömungsrichtung vorgeschaltet. In die Einsetzöffnung 13 ist ein Stopfen 15 bis zu einem umfangsseitig umlaufenden Ringabsatz 16 einsetzbar. Der Ringabsatz 16 ist durch wenigstens eine Nut 29 unterbrochen, die zur Bildung eines Zuführkanales 11 vorgesehen ist. Während der Außenumfang des Stopfens 15 die wenigstens eine Nut 14 zu einem Einlaufkanal 30 schließt, schließt die Stirnseite des Stopfens 14 die mindestens eine Nut 11 längsseitig zu einem Zuführkanal 11. An der der Drallkammer 9 zugewandten Stirnseite des Stopfens 15 weist der Stopfen eine Einsenkung 17 auf. In den Fig. 1 bis 3, 5 und 6 ist erkennbar, dass der Düsenkorpus 8 auf seiner Zulaufseite ZS mit einem Vorsatz- oder Filtersieb 18 verbindbar und vorzugsweise verrastbar ist. Dieses Vorsatzsieb 18 filtert die im anströmenden Wasserstrom mitgeführten Schmutzpartikel und Kalkreste aus, die andernfalls die Funktion des Strahlreglers 1 beeinträchtigen könnten.The at least one jet splitter 2 of the jet regulator 1 is designed as an atomizer nozzle, which divides the inflowing water flow into an essentially hollow cone-shaped water jet and which, even with a comparatively low flow rate, is still characterized by good jet splitting and splitting. The atomizer nozzle serving as a jet splitter 2 has a nozzle body 8 which can be connected to the inner housing 3 on the front edge of the inner housing 3 on the inlet side and can preferably be locked in place. In the nozzle body 8 there is a swirl chamber 9 which has a chamber section 10 which is essentially cylindrical or disk-shaped in terms of the clear cross section on the inflow side. At least one feed channel 11, which is oriented transversely and preferably at right angles to the longitudinal axis of the nozzle and runs tangentially into the swirl chamber 2, opens into the swirl chamber 9. For this purpose, several feed channels 11, each formed by a groove 29, open out into the swirl chamber 2 and are spaced evenly apart from one another in the circumferential direction . The swirl chamber 9 tapers in the outflow direction in the shape of a funnel in the direction of a nozzle channel 12. The funnel-shaped section of the swirl chamber 9 is designed in its clear cross section such that the swirl chamber 9 has the shape of a conical or rotationally hyperbolic funnel in the direction of the nozzle channel 5. The atomizer nozzle serving as a jet splitter 2 has an inflow-side insertion opening 13 in its nozzle body 8 . At At least one groove 14 intended to form an inlet channel 30 is provided on the peripheral wall of this insertion opening 13 . Each feed channel 11 is preceded in the direction of flow by an inlet channel 30 oriented in the longitudinal direction of the nozzle. A plug 15 can be inserted into the insertion opening 13 up to a circumferential annular shoulder 16 . The annular shoulder 16 is interrupted by at least one groove 29 which is provided to form a feed channel 11 . While the outer circumference of the plug 15 closes the at least one groove 14 to form an inlet channel 30, the end face of the plug 14 closes the at least one groove 11 on the longitudinal side to form a feed channel 11. On the end face of the plug 15 facing the swirl chamber 9, the plug has a depression 17 on. In the Figures 1 to 3 , 5 and 6 it can be seen that the nozzle body 8 can be connected and preferably latched on its inlet side ZS to an attachment or filter screen 18 . This attachment filter 18 filters out the dirt particles and lime residues carried along in the oncoming water flow, which could otherwise impair the function of the jet regulator 1 .

Die als Strahlzerleger 2 dienende Zerstäuberdüse teilt den zuströmenden Wasserstrom auf, wobei dieser Wasserstrom in einen Spray aus feinen Tröpfchen (Nebel) zerstäubt und ein Aerosol aus mit Umgebungsluft vermischten feinen Tröpfchen gebildet wird. Dieser aus feinen Tröpfchen gebildete Spray tritt aus der Zerstäuberdüse als hohlkegelförmiger Strahl aus, der aus separierten Flüssigkeitsanteilen gebildet ist. Dieser hohkegelförmige Wasserstrahl ist in Figur 2 durch gestrichelte Linien 31 angedeutet. In Strömungsrichtung unterhalb der mindestens einen Durchtrittsöffnung 7 des Belüftungskanals 5 ist eine ringförmig umlaufende Auftreffzone 19 angeordnet, in welcher der hohlkegelförmig aufgeteilte Wasserstrahl am Gehäuseinnenumfang des Innengehäuses 3 auftrifft. Der Gehäuseinnenraum des Innengehäuses 3 dient dabei als Mischkammer, in welcher der hohlkegelförmig aufgeteilte Wasserstrahl mit der von der wenigstens einen Durchtrittsöffnung 7 kommenden Umgebungsluft durchmischt wird, bevor der luftdurchmischte Wasserstrahl in Strömungsrichtung nach der Aufprallzone 19 wieder zu einem perlend-weichen Auslaufstrahl mit homogenem zylindrischen Strahlaußenumfang geformt wird. Dabei werden die aus der Zerstäuberdüse noch als feiner Nebel austretenden Wassertröpfchen, die mit Keimen belastet und beim Einatmen ein Gesundheitsrisiko beinhalten können, im Innengehäuse 3 in Strömungsrichtung unterhalb der Aufprallzone 19 zu einem homogenen und insoweit gesundheitlich unbedenklichen Auslaufstrahl geformt.The atomizing nozzle serving as the jet splitter 2 divides the inflowing water flow, this water flow being atomized into a spray of fine droplets (mist) and an aerosol of fine droplets mixed with ambient air being formed. This spray, formed from fine droplets, emerges from the atomizer nozzle as a hollow cone-shaped jet, which is formed from separated liquid components. This cone-shaped water jet is in figure 2 indicated by dashed lines 31. In the direction of flow below the at least one through-opening 7 of the ventilation duct 5 there is a ring-shaped peripheral impingement zone 19 in which the water jet, divided in the shape of a hollow cone, impinges on the inner circumference of the inner housing 3 . The housing interior of the inner housing 3 serves as Mixing chamber in which the water jet divided into a hollow cone is mixed with the ambient air coming from the at least one passage opening 7, before the air-mixed water jet is formed back into a soft, sparkling discharge jet with a homogeneous cylindrical jet outer circumference in the direction of flow after the impact zone 19. The water droplets emerging from the atomizer nozzle as a fine mist, which are contaminated with germs and can pose a health risk when inhaled, are formed in the inner housing 3 in the direction of flow below the impact zone 19 to form a homogeneous outlet jet that is harmless to health.

Um eine gleichmäßige Durchmischung in dem als Mischkammer dienenden Gehäuseinnenraum des Innengehäuses 3 zu bewerkstelligen, ist der Belüftungskanal 5 als ein zwischen Innengehäuse 3 und Außengehäuse 4 angeordneter Ringspalt ausgebildet. Dieser Ringspalt kann um das Innengehäuse 3 umlaufen und/oder auch zumindest in einem Teilbereich der Kanal-Längserstreckung segmentiert sein. Um die angestrebte gleichmäßige Durchmischung noch zusätzlich zu begünstigen, sind am Gehäuseumfang des Innengehäuses 3 zumindest zwei und vorzugsweise mehrere, in insbesondere gleichmäßigen Abständen voneinander beabstandete Durchtrittsöffnungen 7 vorgesehen.In order to bring about uniform mixing in the housing interior of the inner housing 3 serving as a mixing chamber, the ventilation channel 5 is designed as an annular gap arranged between the inner housing 3 and the outer housing 4 . This annular gap can run around the inner housing 3 and/or be segmented at least in a partial area of the longitudinal extension of the channel. In order to further promote the desired uniform mixing, at least two and preferably several through-openings 7 are provided on the housing circumference of the inner housing 3 , spaced apart from one another in particular at equal distances.

Der im Bereich zwischen Innen- und Außengehäuse 3, 4 gebildete, wenigstens eine Belüftungskanal 5 reduziert bereits die Übertragung der durch das durchströmende Wasser im Strahlregler 1 verursachten Störgeräusche. Um diese Störgeräusche noch zusätzlich zu reduzieren und um die Wahrnehmung dieser Störgeräusche im Umfeld des Strahlreglers 1 noch zusätzlich zu vermindern, ist in dem wenigstens einen Belüftungskanal 5 mindestens eine Querschnittsverengung 20 ausgebildet ist. Durch diese mindestens eine, im wenigsten einen Belüftungskanal 5 vorgesehene Querschnittsverengung 20 wird ein Schallhindernis gebildet, das die Übertragung dieser Störgeräusche nach außen zusätzlich reduziert. Diese Querschnittsverengung 20 ist hier als ein am Innenumfang des Außengehäuses 4 vorstehender Ringflansch ausgebildet. Dabei ist die Querschnittsverengung 20 in Strömungsrichtung des durch den Strahlregler 1 strömenden Wasserstrahls unterhalb der wenigstens einen Durchtrittsöffnung 7 und somit in Einströmrichtung der Umgebungsluft im Belüftungskanal 5 vor den Durchtrittsöffnungen 7 angeordnet. Um die Wahrnehmung solcher Störgeräusche im Umfeld des Strahlreglers 1 noch zusätzlich zu reduzieren, ist die Einlauföffnung 6 des wenigstens einen Belüftungskanals 5 an der Auslaufseite des Strahlreglers 1 angeordnet. In Figur 5 ist besonders gut erkennbar, dass zu diesem Zweck auch der ablaufseitige Stirnrandbereich des Außengehäuses 4 in Richtung zum Innengehäuse 3 abgewinkelt ist. Somit weist die Einlauföffnung 6 im Vergleich zum lichten Kanalquerschnitt des Belüftungskanals 5 in dem in Strömungsrichtung der im Belüftungskanal 5 geführten Umgebungsluft nachfolgenden Kanalabschnitt einen reduzierten Querschnitt auf, so dass der Austritt der im Belüftungskanal 5 reflektierten Störgeräusche noch zusätzlich erschwert und ein geräuscharmer Betrieb des erfindungsgemäßen Strahlreglers 1 noch zusätzlich begünstigt wird.The at least one ventilation channel 5 formed in the area between the inner and outer housing 3, 4 already reduces the transmission of the noise caused by the water flowing through in the aerator 1. In order to further reduce this background noise and to further reduce the perception of this background noise in the area surrounding the jet regulator 1 , at least one cross-sectional constriction 20 is formed in the at least one ventilation duct 5 . Through this at least one cross-sectional constriction 20 provided in at least one ventilation duct 5 a sound barrier is formed, which additionally reduces the transmission of this noise to the outside. This cross-sectional constriction 20 is designed here as an annular flange protruding on the inner circumference of the outer housing 4 . The cross-sectional constriction 20 is arranged below the at least one passage opening 7 in the direction of flow of the water jet flowing through the jet regulator 1 and thus in front of the passage openings 7 in the inflow direction of the ambient air in the ventilation duct 5 . In order to further reduce the perception of such disturbing noises in the vicinity of the aerator 1 , the inlet opening 6 of the at least one ventilation duct 5 is arranged on the outlet side of the aerator 1 . In figure 5 It is particularly easy to see that for this purpose the end edge area of the outer housing 4 on the outlet side is also angled in the direction of the inner housing 3 . The inlet opening 6 therefore has a reduced cross section compared to the clear channel cross section of the ventilation duct 5 in the downstream duct section in the flow direction of the ambient air guided in the ventilation duct 5, so that the exit of the noise reflected in the ventilation duct 5 is made even more difficult and low-noise operation of the jet regulator according to the invention 1 is additionally favored.

Um eine gute Durchmischung der in den Gehäuseinnenraum des Innengehäuses 3 eingesaugten Umgebungsluft einerseits mit dem das Innengehäuse durchströmenden Wasser andererseits zu begünstigen, ist es vorteilhaft, wenn im Gehäuseinnenraum des Innengehäuses 3 Strömungshindernisse vorgesehen sind. Wie in den Figuren 2 bis 5 erkennbar ist, verjüngt sich dazu das Innengehäuse 3 zu seiner Auslaufstirnseite hin stufenförmig. Dabei können die am Gehäuseinnenumfang des Innengehäuses 3 vorgesehenen Stufen - wie hier - um den Gehäuseinnenumfang umlaufen oder auch segmentiert oder unterbrochen sein. Dabei wird eine gute Durchmischung von Luft und Wasser bereits begünstigt, wenn am Gehäuseinnenumfang des Innengehäuses 3 zumindest eine solche Stufe 21 vorgesehen ist.In order to promote good mixing of the ambient air sucked into the housing interior of the inner housing 3 on the one hand and the water flowing through the inner housing on the other hand, it is advantageous if flow obstacles are provided in the housing interior of the inner housing 3 . As in the Figures 2 to 5 can be seen, the inner housing 3 tapers towards its outlet end face in a stepped manner. The steps provided on the inner circumference of the inner housing 3 can run around the inner circumference of the housing or be segmented or interrupted, as is the case here. Included a good mixing of air and water is already promoted if at least one such step 21 is provided on the inner circumference of the inner housing 3 .

Im Gehäuseinnenraum des Innengehäuses 3 kann eine in Figur 5 durch strichpunktierte Linien angedeutete Blende 32 vorgesehen sein, die in der von der Zulaufseite ZS zur Ablaufseite AS orientierten Strömungsrichtung mit vorzugsweise geringem Abstand unterhalb der Durchtrittsöffnungen 7 angeordnet ist. Diese Blende 32 weist eine zentrale Öffnung auf, die den lichten Querschnitt des Innengehäuses 3 in diesen Bereich auf den Öffnungsquerschnitt der Blende 32 begrenzt. Die Blende 32 ist vorzugsweise als Lochscheibe ausgebildet, die in das Innengehäuse 3 eingesetzt ist. Die Blende 32 unterteilt den Gehäuseinnenraum des Innengehäuses 3 in einen im Bereich der Durchtrittsöffnungen 7 befindlichen Lufteintrittsraum sowie in eine unterhalb der Blende 32 vorgesehene Mischkammer. Die Öffnung der Blende 32 umschließt den aus der Zerstäuberdüse kommenden und dort hohlkegelförmig austretenden Wasserstrahl vorzugsweise mit Abstand. Die Blende 32 verhindert, dass Aerosole oder Kollisionswasser, das durch Auftreffen des Wassers am Innengehäuse entstehen kann, durch die Durchtrittsöffnungen 7 hindurch austritt.In the housing interior of the inner housing 3, an in figure 5 baffle 32 indicated by dot-dash lines may be provided, which is arranged in the direction of flow oriented from the inlet side ZS to the outlet side AS at a preferably small distance below the passage openings 7 . This panel 32 has a central opening which limits the clear cross section of the inner housing 3 in this area to the opening cross section of the panel 32 . The screen 32 is preferably designed as a perforated disk that is inserted into the inner housing 3 . The panel 32 divides the housing interior of the inner housing 3 into an air inlet space located in the area of the passage openings 7 and into a mixing chamber provided below the panel 32 . The opening of the diaphragm 32 encloses the water jet coming from the atomizer nozzle and exiting there in the form of a hollow cone, preferably at a distance. The screen 32 prevents aerosols or collision water, which can result from the water hitting the inner housing, from escaping through the passage openings 7 .

An der Auslaufstirnseite des Innengehäuses 3 ist ein Strömungsgleichrichter 22 vorgesehen, der das durch das Innengehäuse 3 zuströmende und mit Umgebungsluft durchmischte Wasser in Auslaufrichtung vergleichmäßigt. Dieser Strömungsgleichrichter 22 weist eine Gitter-, Waben- oder - wie hier - Netzstruktur mit strömungsführenden Durchflusslöchern 23 auf. Zumindest die Mehrzahl der Durchflusslöcher 23 hat eine Längserstreckung in Durchflussrichtung, die im Vergleich zur maximalen Weite dieser Durchflusslöcher 23 größer ist. Um einer unerwünschten Manipulation am Strömungsgleichrichter 22 des Strahlreglers 1 entgegenzuwirken, ist der Strömungsgleichrichter 22 an das Innengehäuse 3 innenumfangsseitig angeformt. Die Durchflusslöcher 23 sind so angeordnet und ausgebildet, dass der Wasserstrahl stromabwärts zu einem einheitlichen Auslaufstrahl rekombiniert. Dem Strömungsgleichrichter 22 ist wenigstens eine Lochplatte 24 in Strömungsrichtung vorgeschaltet, die Löcher 25 hat, deren maximale Weite im Vergleich zur Weite der Durchflusslöcher 23 des Strömungsgleichrichters 22 kleiner ist. Die Lochplatte 24 weist hier eine die Löcher 25 umgrenzende Gitterstruktur auf.A flow straightener 22 is provided on the outlet end face of the inner housing 3, which evens out the water flowing through the inner housing 3 and mixed with ambient air in the outlet direction. This flow straightener 22 has a lattice, honeycomb or—as here—net structure with flow-guiding throughflow holes 23 . At least the majority of the through-flow holes 23 has a longitudinal extension in the through-flow direction that is larger compared to the maximum width of these through-flow holes 23 . In order to prevent undesired manipulation of the flow straightener 22 of the jet regulator 1 counteract this, the flow straightener 22 is integrally formed on the inner circumference of the inner housing 3 . The flow-through holes 23 are arranged and formed in such a way that the water jet recombines into a uniform outlet jet downstream. The flow straightener 22 is preceded by at least one perforated plate 24 in the direction of flow, which has holes 25 whose maximum width is smaller than the width of the flow holes 23 of the flow straightener 22 . The perforated plate 24 here has a lattice structure which delimits the holes 25 .

Die wenigstens eine Lochplatte 24 ist in den Gehäuseinnenraum des Innengehäuses 3 eingesetzt und vorzugsweise auf den Strömungsgleichrichter 22 aufgelegt.The at least one perforated plate 24 is inserted into the housing interior of the inner housing 3 and preferably placed on the flow straightener 22 .

Um das Außengehäuse des in Fig. 5 gezeigten Strahlreglers 1 am Wasserauslauf einer sanitären Auslaufarmatur montieren zu können, weist das Außengehäuse 4 an seinem zuströmseitigen Gehäuseumfang eine hier als Gewinde 28 ausgebildete Kupplung auf, die mit einer beispielsweise durch ein Gegengewinde gebildeten Gegenkupplung am Wasserauslauf der sanitären Auslaufarmatur zusammenwirkt.Around the outer casing of the in figure 5 To be able to mount the aerator 1 shown on the water outlet of a sanitary outlet fitting, the outer housing 4 has on its inflow-side housing circumference a coupling designed here as a thread 28, which interacts with a counter-coupling formed, for example, by a mating thread on the water outlet of the sanitary outlet fitting.

Das Innengehäuse 3 weist zumindest einen Einsetzanschlag 26 auf, wobei das Innengehäuse 3 in das Außengehäuse 4 einsetzbar ist, bis dieser zumindest eine Einsetzanschlag 26 auf einem am Gehäuseinnenumfang des Außengehäuses 4 vorgesehenen Auflager aufliegt. Als Auflager dient hier die zulaufseitige Stirnfläche des als Querschnittsverengung dienenden Ringflansches 20. Der Einsetzanschlag 26 ist hier als segmentierter Ringabsatz am Außenumfang des Innengehäuses 3 ausgebildet.The inner housing 3 has at least one insertion stop 26 , the inner housing 3 being able to be inserted into the outer housing 4 until this at least one insertion stop 26 rests on a support provided on the inner circumference of the outer housing 4 . The face of the annular flange 20 on the inlet side, which serves as a narrowing of the cross section, serves as a support here.

Der Strahlregler 1 hat einen einzigen und vorzugsweise zentralen Strahlzerleger 2. Dabei sind die Längsachsen des Strahlzerlegers 2, des Innengehäuses 3 sowie des Außengehäuses 4 koaxial zueinander angeordnet. Der Strahlzerleger 2 ist auf der zulaufseitigen Stirnseite des Innengehäuses 3 mit diesem lösbar verbindbar und vorzugsweise lösbar verrastbar.The jet regulator 1 has a single and preferably central jet splitter 2. The longitudinal axes of the Beam splitter 2, the inner housing 3 and the outer housing 4 are arranged coaxially to one another. The jet splitter 2 can be releasably connected and preferably releasably latched to the inner housing 3 on the inlet-side end face of the latter.

Der hier dargestellte Strahlbelüfter 1 zeichnet sich auch bei sehr niedrigen Durchflussklassen und -leistungen durch eine sichere Funktionsweise aus. Dabei wird eine zentrale Zerstäuberdüse als Strahlzerleger 2 verwendet. In dieser Zerstäuberdüse wird ein hohlkegelförmiger Wasserstrahl gebildet, der in den als Mischkammer dienenden Gehäuseinnenraum des Innengehäuses 3 einströmt und innenumfangsseitig in der Aufprallzone 19 am Innengehäuse 3 auftrifft. Der aus dem Strahlzerleger 2 austretende hohlkegelförmige Wasserstrahl zeigt kaum eine Rotationsbewegung. Die Länge des Innengehäuses 3 in dem unterhalb der Durchtrittsöffnungen 7 angeordneten Gehäuseabschnitt ist ausreichend lang bemessen, so dass sich das am Auslaufende des Innengehäuses 3 im Bereich des Strömungsgleichrichters 22 aufstauende Wasser nicht bis in den Bereich der Auftreffzone 19 zurückstauen kann. Ein Absatz am abströmseitigen Ende des Innengehäuses 3 kann die Durchmischung des Wassers mit der Umgebungsluft noch zusätzlich verbessern.The jet aerator 1 shown here is characterized by reliable functioning even at very low flow rates and capacities. In this case, a central atomizer nozzle is used as the jet splitter 2 . A hollow cone-shaped water jet is formed in this atomizer nozzle, which flows into the housing interior of the inner housing 3 serving as a mixing chamber and impinges on the inner peripheral side in the impact zone 19 on the inner housing 3 . The water jet emerging from the jet splitter 2 in the form of a hollow cone shows hardly any rotational movement. The length of the inner housing 3 in the housing section arranged below the passage openings 7 is dimensioned sufficiently long so that the water accumulating at the outlet end of the inner housing 3 in the area of the flow straightener 22 cannot back up in the area of the impact zone 19. A shoulder at the outflow end of the inner housing 3 can further improve the mixing of the water with the ambient air.
