Description
Die Erfindung betrifft eine Wasserspielanordnung mit einer wenigstens einen gebündelten Wasserstrahl abgebenden Düsenanordnung.The invention relates to a fountain assembly with a nozzle arrangement emitting at least one bundled jet of water.
Wasserspielanordnungen sind in großer Vielfalt bekannt, wobei eine Art solcher Wasserspielanordnungen eine Düsenanordnung zur Erzeugung wenigstens einen gebündelten Wasserstrahl enthält. Form und/oder Richtung des Wasserstrahls können dabei zeitlich variieren. Bekannt sind insbesondere auch Wasserspielanordnungen mit bewegten Düsenanordnungen oder mit durch gesteuerte Pumpen oder Ventile intermittierend in als isolierte fliegende Wassersäulen erscheinenden Strahlabschnitten abgegebenen Wasserstrahlen, bekannt als sogenannte Jumping-Jet-Wasserspiele.Water play arrangements are known in great variety, with one type of such play arrangements containing a nozzle arrangement for generating at least one bundled jet of water. The shape and / or direction of the water jet can vary over time. In particular, water feature arrangements with moving nozzle arrangements or with water jets emitted intermittently by controlled pumps or valves in jet sections appearing as isolated flying water columns are known, known as so-called jumping-jet water features.
Der vorliegenden Erfindung liegt die Aufgäbe zugrunde, eine neuartige Wasserspielanordnung mit einer wenigstens einen gebündelten Wasserstrahl abgebenden Düsenanordnung anzugeben.The object of the present invention is to specify a novel water play arrangement with a nozzle arrangement which delivers at least one bundled water jet.
Die Erfindung ist im Patentanspruch 1 beschrieben. Die abhängigen Ansprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.The invention is described in claim 1. The dependent claims contain advantageous refinements and developments of the invention.
Die Erfindung erzielt mit einfachen Mitteln eine effektvoll variierende Form der Abgabe eines gebündelten Wasserstrahls, welcher dem Benutzer ähnlich den eingangs erwähnten combigesteuerten Jumping-Jet-Wasserspielanordnungen als scheinbar voneinander unabhängige isoliert fliegende Strahlabschnitte erscheint. Die Strahlaustrittsrichtung des Wasserstrahls am Ausgang der Düsenanordnung ist vorzugsweise überwiegend vertikal ausgerichtet und weist bevorzugt einen Winkel von wenigstens 45°, insbesondere wenigstens 60° gegen die Horizontale auf. Die getrennten Abschnitte des Wasserstrahls sind im Gegensatz zu Wasserstrahlen von Bewässerungsanlagen vorteilhaft über die gesamte Reichweite eng gebündelt.The invention achieves, by simple means, an effectively varying form of delivery of a bundled jet of water, which appears to the user as seemingly independent isolated flying jet sections similar to the combig-controlled jumping-jet water play arrangements mentioned above. The jet exit direction of the water jet at the outlet of the nozzle arrangement is preferably oriented predominantly vertically and preferably has an angle of at least 45 °, in particular at least 60 ° to the horizontal. The separate sections of the water jet are in contrast to water jets of irrigation systems advantageously tightly bundled over the entire range.
Die Abgabe zeitlich aufeinander folgender Strahlabschnitte in verschiedene, vorteilhafterweise um einen Raumwinkel (in einem für den Betrachter feststehenden Koordinatensystem) von wenigstens 15°, vorzugsweise wenigstens 30°, insbesondere wenigstens 45° getrennte Richtungen ist ein solcher Eindruck unabhängiger Strahlabschnitte mit zufälliger Abgaberichtung besonders ausgeprägt. Die Variation der Abgaberichtung zeitlich aufeinander folgender Strahlabschnitte kann in einer bevorzugten Ausführungsform dadurch gegeben sein, dass die Relativbewegung von Düsenanordnung und Einrichtung zur Unterbrechung des Wasserstrahls eine Bewegung der Düsenanordnung relativ zur Umgebung beinhaltet, insbesondere eine Drehbewegung, vorzugsweise um eine im wesentlichen vertikale Düsendrehachse. Die Einrichtung zur Unterbrechung des Wasserstrahls steht daher in bevorzugter besonders einfacher und kostengünstiger Ausführung bezüglich der Umgebung fest. Die Einrichtung zur Unterbrechung des Wasserstrahls ist dabei vorteilhafterweise so geformt, dass je vollständiger Umdrehung der Düsenanordnung um die Düsendrehachse wenigstens je zwei, vorzugsweise wenigstens je drei Unterbrechungen und Freigaben eines Wasserstrahls auftreten.The delivery of temporally successive beam sections in different, advantageously by a solid angle (in a fixed for the viewer coordinate system) of at least 15 °, preferably at least 30 °, in particular at least 45 ° separate directions such an impression of independent beam sections with random discharge direction is particularly pronounced. In a preferred embodiment, the variation of the discharge direction of temporally successive jet sections can be provided by the relative movement of the nozzle arrangement and device for interrupting the water jet comprising a movement of the nozzle arrangement relative to the environment, in particular a rotational movement, preferably about a substantially vertical nozzle rotation axis. The device for interrupting the water jet is therefore fixed in a preferred particularly simple and inexpensive design with respect to the environment. The device for interrupting the water jet is advantageously formed so that each complete rotation of the nozzle assembly to the nozzle axis of rotation at least two, preferably at least three interruptions and releases of a water jet occur.
Die Drehbewegung der Düsenanordnung kann auf verschiedene an sich bekannte Arten erfolgen. In bevorzugter Ausführungsform besitzt die Strahlaustrittsrichtung des wenigstens einen Wasserstrahls eine bezüglich der Düsendrehachse tangentiale Komponente und die Drehbewegung der Düsenanordnung erfolgt unter Einwirkung der Rückstoßkraft des austretenden gebündelten Wasserstrahls. Die Drehbewegung der Düsenanordnung bewirkt auch eine nicht radial bezüglich der Drehachse liegende Richtung der einzelnen Strahlabschnitte und verstärkt dadurch den Eindruck der gegenseitigen Unabhängigkeit der Strahlabschnitte, auch wenn diese auf denselben Wasserstrahl der Düsenanordnung zurückgehen. Die Düsenanordnung kann auch aus mehreren, vorzugsweise unterschiedlich ausgerichteten Einzeldüsen mehrere gebündelte Wasserstrahlen abgeben.The rotational movement of the nozzle arrangement can be carried out in various ways known per se. In a preferred embodiment, the jet exit direction of the at least one water jet has a component which is tangential with respect to the nozzle rotational axis, and the rotational movement of the nozzle arrangement takes place under the effect of the repulsive force of the exiting bundled water jet. The rotational movement of the nozzle assembly also causes a non-radial direction of the axis of rotation of the individual beam sections and thereby amplifies the impression of mutual independence of the beam sections, even if these on the same jet of water nozzle arrangement decline. The nozzle arrangement can also deliver a plurality of bundled water jets from a plurality of, preferably differently oriented, individual nozzles.
In anderer Ausführung kann auch die Einrichtung zur Unterbrechung des Wasserstrahls relativ zur Umgebung bewegt sein. Bei feststehender Düsenanordnung weist diese zur Erzeugung von in verschiedenen Richtungen fliegenden Strahlabschnitten vorteilhafterweise mehrere unterschiedlich ausgerichtete Düsen zur Abgabe mehrerer gebündelter Wasserstrahlen auf. Die Relativbewegung der Düsenanordnung gegenüber der Einrichtung zur Unterbrechung des Wasserstrahls kann auch durch eine Kombination von Bewegung der Düsenanordnung und der Einrichtung zur Unterbrechung des Wasserstrahls gegenüber der Umgebung gegeben sein, wobei Drehbewegungen auch um für die Düsenanordnung und für die Einrichtung zur Unterbrechung des Wasserstrahls verschieden sein können.In another embodiment, the device for interrupting the water jet can be moved relative to the environment. When the nozzle arrangement is fixed, it advantageously has a plurality of differently aligned nozzles for emitting a plurality of bundled water jets in order to generate beam sections which fly in different directions. The relative movement of the nozzle assembly relative to the water jet interrupting means may also be through a combination of movement of the nozzle assembly and the means for interrupting the water jet from the environment, with rotational movements also being different for the nozzle assembly and the water jet interrupting means can.
Bei Vorliegen von mehreren Düsen zur Abgabe mehrerer gebündelter Wasserstrahlen kann die Einrichtung zur Unterbrechung des Wasserstrahls die mehreren Wasserstrahlen synchron freigeben und sperren. In bevorzugter Ausführungsform sind die aus den verschiedenen Wasserstrahlen freigegebenen Strahlabschnitte zeitlich gegeneinander versetzt.In the presence of multiple nozzles for dispensing multiple bundled jets of water, the means for interrupting the jet of water can synchronously release and lock the multiple jets of water. In a preferred embodiment, the beam portions released from the various water jets are offset in time from each other.
Die Einrichtung zur Unterbrechung des Wasserstrahls ist vorteilhafterweise mit der Düsenanordnung verbunden und unter Beibehaltung dieser Verbindung aus einer Betriebsstellung mit der beschriebenen Unterteilung des von der Düsenanordnung kontinuierlich abgegebenen Wasserstrahls in voneinander durch Lücken getrennte Strahlabschnitte verlagerbar in eine Parkstellung, in welcher der von der Düsenanordnung abgegebene Wasserstrahl von der Einrichtung zur Unterbrechung des Wasserstrahls unbeeinflusst ist. Die Wasserspielanordnung kann dadurch alternativ mit unterbrochenem oder mit kontinuierlichem Strahlbild betrieben werden. Die Umstellung kann beispielsweise durch eine aus einem Halter entnehmbare und/oder eine verschwenkbare Blende gegeben sein. Die Einrichtung zur Unterbrechung des Wasserstrahls kann für unterschiedliche Gestaltung der Strahlunterbrechung verstellbar sein, was auch durch mehrere Blenden, z. B. auswechselbar in einer Blendenhalterung eingesetzt und/oder alternativ aus ihren Parkstellungen in die Betriebsstellung schwenkbar sein können, gegeben sein kann.The device for interrupting the water jet is advantageously connected to the nozzle assembly and while maintaining this connection from an operating position with the described subdivision of the nozzle assembly continuously discharged water jet in each other by gaps separate beam sections displaceable in a parking position in which the output from the nozzle assembly water jet is unaffected by the device for interrupting the water jet. The water play arrangement can thereby alternatively with interrupted or with continuous Blast image operated. The conversion can be given for example by a removable from a holder and / or a pivotable aperture. The device for interrupting the water jet can be adjusted for different design of the beam interruption, which can also be achieved by a plurality of apertures, for. B. used interchangeably in a diaphragm holder and / or alternatively can be pivoted from their parking positions in the operating position, can be given.
Die Einrichtung zur Unterbrechung des Wasserstrahls enthält in bevorzugter Ausführung eine flächige Blende mit wenigstens einer, vorzugsweise mehreren Blendenöffnungen zum Durchtritt des Wasserstrahls. Bei der Relativbewegung trifft ein von der Düsenanordnung kontinuierlich abgegebener Strahl alternierend auf eine den Strahl sperrende Blendenfläche oder eine den Strahl freigebende Blendenöffnung und wird so in einzelne freigegebene Strahlabschnitte unterteilt. Die den Strahl sperrenden Blendenflächen bewirken Lücken zwischen aufeinanderfolgenden Strahlabschnitten desselben Strahls. In anderer Ausführung kann anstelle der Blende mit Blendenöffnungen auch eine Gruppe von mehreren beabstandeten Blendenflächen vorgesehen sein, deren Abstände dann die Wirkung der Blendenöffnungen erbringen.The device for interrupting the water jet contains in a preferred embodiment, a flat panel with at least one, preferably a plurality of apertures for the passage of the water jet. In the relative movement, a jet continuously emitted by the nozzle arrangement alternately strikes a diaphragm surface blocking the beam or an aperture opening which releases the beam and is thus subdivided into individual released beam sections. The beam-blocking diaphragm surfaces cause gaps between successive beam portions of the same beam. In another embodiment, instead of the diaphragm with apertures, a group of several spaced diaphragm surfaces may be provided, the distances then provide the effect of the apertures.
In vorteilhafter Ausführungsform weist die Einrichtung zur Unterbrechung des Wasserstrahls Mittel zur Umlenkung gesperrter Anteile des Wasserstrahls nach unten auf. Hierdurch wird vermieden, dass die gesperrten Strahlanteile unkontrolliert seitlich austreten. In bevorzugter Ausführungsform bildet die Einrichtung zur Unterbrechung des Wasserstrahls einen Hohlraum um den Strahlaustritt der Düsenanordnung.In an advantageous embodiment, the device for interrupting the water jet means for deflecting blocked portions of the water jet down. This avoids that the blocked beam portions escape uncontrolled side. In a preferred embodiment, the device for interrupting the water jet forms a cavity around the jet outlet of the nozzle assembly.
Die Zeitdauer der Freigabe des Wasserstrahls, welche die Länge der Strahlabschnitte bestimmt, beträgt vorteilhafterweise höchstens das 4-fache, insbesondere höchstens das 2-fache der Zeitdauer der Sperrung desselben Wasserstrahls, welche die Länge der Strahllücken bestimmt. Vorteilhafterweise beträgt die Zeitdauer der Freigabe des Wasserstrahls wenigstens das 0,25-fache, insbesondere wenigstens das 0,5-fache der Zeitdauer der Sperrung desselben Wasserstrahls. In bevorzugter Ausführung sind die Zeitdauern von Freigabe und Sperrung annähernd gleich.The time duration of the release of the water jet, which determines the length of the beam sections, is advantageously at most 4 times, in particular at most twice, the duration of the blocking of the same water jet, which determines the length of the beam gaps. Advantageously, the time duration of the release of the water jet is at least 0.25 times, in particular at least 0.5 times the duration of the blocking of the same water jet. In a preferred embodiment, the periods of release and blocking are approximately equal.

In Fig. 1 ist eine Düsenanordnung DA mit einer einzigen Düse D1 zur Abgabe eines gebündelten Wasserstrahls dargestellt. Die Düsenanordnung ist am oberen Ende eines wasserführenden Rohrs RO angeordnet und z. B. aus einer Tauchpumpe PU gespeist, welche in einem Teich oder Becken unter der Wasseroberfläche WO platziert ist. Ein rechtwinkliges, für den Betrachter feststehendes xyz-Koordinatensystem mit vertikaler z-Achse ist mit eingezeichnet.In Fig. 1, a nozzle assembly DA is shown with a single nozzle D1 for discharging a bundled jet of water. The nozzle assembly is disposed at the upper end of a water-carrying pipe RO and z. B. from a submersible pump PU, which is placed in a pond or pool under the water surface WO. A rectangular, for the viewer fixed xyz coordinate system with a vertical z-axis is marked with.
Die Düsenanordnung DA ist um eine Rotationsachse RA drehbar. Die Drehung kann beispielsweise durch mit der Düsenanordnung drehbare Rückstoßdüsen RD erfolgen, welche mit bezüglich der Rotationsachse überwiegend tangentialer Ausstoßrichtung Wasser abgeben und den Rückstoß der abgegebenen Wassermenge als Antriebskraft für die Drehung der Düsenanordnung ausnutzen. Die Rückstoßdüsen RD liegen vorzugsweise unterhalb der Wasseroberfläche WO. Die Drehgeschwindigkeit kann durch bremsend wirkende Lamellen LA, welche vorzugsweise unterhalb der Wasseroberfläche angeordnet und pendelnd gehalten sind, begrenzt werden. Eine besonders vorteilhafte Weise zur Einstellung der Rotationsgeschwindigkeit der Düsenanordnung besteht darin, dass die bremsenden Lamellen höhenverstellbar sind und Stellungen mit verschiedenen Eintauchtiefen und damit auch verschiedenen Bremswirkungen einnehmen können.The nozzle arrangement DA is rotatable about a rotation axis RA. The rotation can take place, for example, by means of thrust nozzles RD which are rotatable with the nozzle arrangement and which release water with an ejection direction which is predominantly tangential with respect to the axis of rotation and utilize the recoil of the discharged water quantity as the driving force for the rotation of the nozzle arrangement. The recoil nozzles RD are preferably below the water surface WHERE. The rotational speed can be limited by braking slats LA, which are preferably arranged underneath the water surface and kept oscillating. A particularly advantageous manner for adjusting the rotational speed of the nozzle arrangement is that the braking lamellae are adjustable in height and can assume positions with different immersion depths and thus also different braking effects.
Ein von der im Beispiel einzigen Düse D1 der Düsenanordnung DA abgegebener gebündelter Wasserstrahl WS kann mit gegen die vorzugsweise im wesentlichen vertikale Rotationsachse RA um einen Winkel NW geneigter Austrittsrichtung aus der Düsenanordnung austreten. Die Ausstoßrichtung des Wasserstrahls läuft durch die Rotationsbewegung der Düsenanordnung auf einer Kegelmantelfläche um die Rotationsachse um. Der Neigungswinkel NW der Ausstoßrichtung beträgt vorzugsweise maximal 45°, insbesondere maximal 30° gegen die Rotationsachse, welche hier im wesentlichen vertikal und damit parallel zur z-Achse verlaufe. Die Strahlaustrittsrichtung ist damit um wenigstens 45°, insbesondere wenigstens 60° gegen die Horizontale nach oben winkelversetzt.A bundled water jet WS emitted by the single nozzle D1 of the nozzle arrangement DA in the example can exit the nozzle arrangement with an outlet direction inclined at an angle NW, which is preferably an essentially vertical axis of rotation RA. The ejection direction of the water jet passes through the rotational movement of the nozzle arrangement on a conical surface around the axis of rotation. The angle of inclination NW of the ejection direction is preferably a maximum of 45 °, in particular a maximum of 30 ° with respect to the axis of rotation, which in this case runs essentially vertically and thus parallel to the z-axis. The beam exit direction is thus angularly offset by at least 45 °, in particular at least 60 °, from the horizontal upwards.
Eine Einrichtung zur Unterbrechung des Wasserstrahls weist im skizzierten Beispiel in Strahlrichtung des Wasserstrahls nach der Düsenanordnung eine flächige Blende BL mit mehreren Blendenöffnungen BO auf. Die Blendenöffnungen sind gegeneinander um die Rotationsachse RA winkelversetzt, vorzugsweise um gleiche Versatzwinkel, angeordnet und so positioniert, dass der Wasserstrahl WS bei seinem Umlauf sukzessive die Blendenöffnungen BO erreicht und dann zum Austritt in Strahlrichtung freigegeben wird, in den Bewegungsabschnitten zwischen den Blendenöffnungen hingegen auf die Unterseite der Blende BF trifft und dadurch gesperrt wird. Hierdurch entstehen zeitlich aufeinanderfolgend und zeitlich beabstandet freigegebene Strahlabschnitte, welche entsprechend den verschiedenen Blendenöffnungen in unterschiedliche Richtungen ausgeworfen werden.A device for interrupting the water jet has in the example shown in the beam direction of the water jet after the nozzle arrangement on a flat aperture BL with multiple apertures BO. The apertures are angularly offset from each other about the axis of rotation RA, preferably at the same offset angle, and positioned so that the water jet WS successively reaches the apertures BO during its circulation and is then released to exit in the beam direction, in the movement sections between the apertures on the Bottom of the aperture BF hits and is thereby blocked. This results in temporally successive and temporally spaced shared beam sections, which are ejected in different directions according to the different apertures.
Die flächige Blende BF, welche auch durch einzelne Blendenflächen gebildet sein kann, ist seitlich als Seitenwand SW nach unten fortgesetzt, so dass ein an der Unterseite der Blende auftretender und von dort abgelenkter Wasserstrahl nicht unkontrolliert seitlich austritt. Der gesperrte Wasserstrahl wird für den Betrachter unsichtbar nach unten abgeleitet und in den Wasservorrat des Teichs oder Beckens zurückgeführt. Die Blendenfläche BF und die Seitenwand SW bilden in der skizzierten vorteilhaften Ausführung einen Hohlraum um die Strahlaustrittsöffnung bzw. die Düsenanordnung.The flat diaphragm BF, which may also be formed by individual diaphragm surfaces, is continued laterally as a side wall SW downwards, so that a water jet occurring at the underside of the diaphragm and deflected from there does not escape laterally in an uncontrolled manner. The blocked water jet is invisibly downwards for the viewer and returned to the water reservoir of the pond or basin. The diaphragm surface BF and the side wall SW form in the sketched advantageous embodiment, a cavity around the jet outlet opening and the nozzle assembly.
Die Blende BF ist vorteilhafterweise an dem Rohr RO befestigt und nicht gedreht. Die Verbindung zu dem Rohr RO kann beispielsweise über die Seitenwand SW und einen Boden oder Radialstreben etc. als Querverbindung zum Rohr RO gegeben sein.The baffle BF is advantageously attached to the tube RO and not rotated. The connection to the pipe RO can be given for example via the side wall SW and a bottom or radial struts etc. as a cross-connection to the pipe RO.
Bei der in Fig. 2 skizzierten Ausführungsform weist die Düsenanordnung DA2 zwei horizontal beabstandet und bezüglich der vertikalen Rotationsachse RA gegenüberliegend angeordnete Düsen D21 und D22 auf, deren Ausstoßrichtungen, wie anhand der um 90° weitergedrehten Düse D21 in Position D21' mit unterbrochener Linie gezeichnet, auch eine tangentiale Komponente bezüglich der Rotationsachse RA aufweisen kann und auf diese, an sich bekannte Weise selbst durch den Strahlausstoß die Düsenanordnung in Rotation versetzt. Der Wasserstrahl aus der Düse D21 ist in Fig. 2 mit S1' bezeichnet.In the embodiment sketched in FIG. 2, the nozzle arrangement DA2 has two nozzles D21 and D22 arranged horizontally spaced apart and opposite each other with respect to the vertical axis of rotation RA, the ejection directions of which are drawn with a broken line as shown by the nozzle D21 rotated further through 90 ° in position D21 '. may also have a tangential component with respect to the axis of rotation RA and in this, known per se, even by the jet ejection, the nozzle assembly is set in rotation. The water jet from the nozzle D21 is designated in FIG. 2 by S1 '.
Die Einrichtung zur Unterbrechung des Wasserstrahls weist wiederum eine flächige, in Fig. 3 in Draufsicht skizzierte Blende BF2 mit drei um gleiche Winkel um die Rotationsachse versetzten Blendenöffnungen BO2 auf. Durch die 180°-Drehsymmetrie der Düsenanordnung und die 120°-Drehsymmetrie der Blendenöffnungen werden die beiden von den Düsen D21 bzw. D22 abgegebenen Wasserstrahlen S1, S2 alternierend als Strahlabschnitte freigegeben (S2) bzw. gesperrt (S1), so dass zeitlich aufeinanderfolgend aus der Blende austretende Strahlabschnitte abwechselnd aus den Düsen D21, D22 kommen und durch den großen Winkelversatz zeitlich aufeinanderfolgender Strahlabschnitte der Eindruck unabhängig und zufällig auftretender Strahlabschnitte für den Betrachter verstärkt ist.The device for interrupting the water jet again has a flat aperture BF2 sketched in plan view in FIG. 3 with three aperture openings BO2 offset by equal angles about the axis of rotation. Due to the 180 ° rotational symmetry of the nozzle arrangement and the 120 ° rotational symmetry of the apertures the two streams of water S1, S2 emitted by the nozzles D21 and D22 are alternately released as beam sections (S2) and blocked (S1), so that jet sections emerging from the screen in succession alternately come from the nozzles D21, D22 and through the large Angular offset temporally successive beam sections of the impression independent and random occurring beam sections is reinforced for the viewer.
Demgegenüber kann durch eine Blende mit gleicher Drehsymmetrie wie die Düsenanordnung eine für alle Wasserstrahlen der Düsenanordnungen synchrone Freigabe bzw. Sperrung erreicht werden.In contrast, can be achieved by a diaphragm with the same rotational symmetry as the nozzle assembly for all water jets of the nozzle assemblies synchronous release or blocking.
Die Blende BF2 ist in dem Beispiel nach Fig. 2 um eine Schwenkgelenkanordnung GA aus der skizzierten Betriebsstellung in eine Parkstellung verschwenkbar, z. B. seitlich der Seitenwand der Einrichtung zur Unterbrechung des Wasserstrahls verlagerbar, wo sie die von der Düsenanordnung abgegebenen Wasserstrahlen nicht beeinflusst. Die Blende kann auch vollständig abnehmbar sein. Bei unbeeinflusst austretendem Strahl beschreibt dieser eine Bahn als Überlagerung einer Drehung mit einer Wurfparabel und bildet ein an sich bekanntes Wasserspiel mit eigenständigen Eindruck. Es können mehrere unterschiedliche Blendenformen auswechselbar vorgesehen sein.The aperture BF2 is in the example of FIG. 2 about a pivot joint assembly GA from the outlined operating position in a parking position pivoted, z. B. laterally of the side wall of the device for interrupting the water jet displaced, where it does not affect the output from the nozzle assembly water jets. The bezel can also be completely removable. In uninfluenced exiting beam this describes a path as a superposition of a rotation with a parabola and forms a per se known water feature with independent impression. There may be provided interchangeable several different aperture forms.
Anstelle einer Bewegung der Düsenanordnung relativ zur Umgebung bei feststehender Blende kann, insbesondere bei einer Düsenanordnung mit mehreren Düsen, auch die Düsenanordnung feststehend und die Einrichtung zur Unterbrechung des Wasserstrahls bewegt sein. Es kann auch eine kombinierte Bewegung von Düsenanordnung und Einrichtung zur Unterbrechung des Wasserstrahls vorliegen. Die in den Ausführungsbeispielen beschriebene Bewegung der Düsenanordnung bei feststehender Einrichtung zur Unterbrechung des Wasserstrahls ist wegen besonders günstiger konstruktiver Ausführung bevorzugt.Instead of a movement of the nozzle assembly relative to the environment with fixed aperture, and in particular with a nozzle arrangement with a plurality of nozzles, the nozzle arrangement can be stationary and the device for interrupting the water jet can be moved. There may also be a combined movement of nozzle assembly and means for interrupting the water jet. The movement of the nozzle assembly described in the embodiments with fixed means for interrupting the Water jet is preferred because of particularly favorable structural design.
