Ein entscheidender Nachteil ist darin zu sehen, daß der radial außen an dem Verteiler abgebbare Mediumstrahl in seiner durch den Auslaßschlitz vorgegebenen Richtungsorientierung nicht beeinflußbar ist, daß infolge der horizontalen Orientierung des Treibmittels sich am Boden des Wasserbeckens eine Horizontalströmung ausbreitet, die dann begünstigt durch den Auftrieb der in die Strahlströmung eingesogenen Luftanteile an den Seitenwänden des Wasserbeckens senkrecht aufsteigt, wobei nachteiligerweise der Benutzer eines solchen Beckens von der im wesentlichen horizontal verlaufenden Strömung nicht erfaßbar ist und die an den Seitenwänden des Beckens aufsteigenden Luftanteile kaum zu einer wirksamen Unterwassermassage beitragen. Insoweit ist mit dieser Einstrahldüse bestenfalls nahe den Seitenwandungen eine "Belüftung" des Becken-Wasserinhalts möglich.Jet nozzles of this type have the disadvantage that the distributor is a large-area device the bottom and the seat of the pool is provided. A key disadvantage is to be seen in the fact that the radially externally emittable on the distributor medium jet in its through the Exhaust slot predetermined direction orientation is not influenced that as a result of horizontal orientation of the blowing agent at the bottom of the water basin Horizontal flow spreads, which then benefits from the buoyancy of the jet flow sucked air rises vertically on the side walls of the pool, whereby disadvantageously the user of such a basin from the substantially horizontal current flowing is not detectable and the rising on the side walls of the pool Air fractions hardly contribute to an effective underwater massage. So far is with this Jet nozzle at best near the side walls "ventilation" of the pool water content possible.

Durch die US 3,905,358 ist eine Hydromassagedüse bekannt, die im Prinzip einer Wasserstrahlpumpe ein in axialer Richtung ausstoßbares Wasser-/Luftgemisch erzeugt, wobei die Richtung des aus der Düsenmündung ausstoßbaren Gemischs mittels einer manuell verschwenkbaren Kugeldüse orientierbar ist.A hydromassage nozzle is known from US Pat. No. 3,905,358 Water jet pump generates a water / air mixture which can be ejected in the axial direction, the Direction of the mixture that can be ejected from the nozzle orifice by means of a manual pivotable ball nozzle is orientable.

Eine Hydromassagedüse gemäß dem Oberbegrift des Anspruchs 1 ist aus der Druckschrift US-A-4 715 071 bekannt.A hydromassage nozzle according to the preamble of claim 1 is known from US-A-4,715,071.

Aufgabe der Erfindung ist es, den Komfort einer ansich bekannten Hydromassagedüse derart zu verbessern, daß sowohl eine Strömung mit im wesentlichen horizontaler Orientierung, wie auch eine Strömung mit im wesentlichen axialer Orientierung aus der Mündung der Hydromassagedüse in den Innenraum des Wasserbeckens abgebbar ist.The object of the invention is to increase the comfort of a hydro massage nozzle known per se improve that both a flow with a substantially horizontal orientation as well as a Flow with an essentially axial orientation from the mouth of the hydromassage nozzle into the Interior of the pool is dispensable.

Eine weitere Aufgabe der Erfindung besteht darin, eine Hydromassagedüse derart auszubilden, daß die Orientierung des aus der Müsenmündung ausstoßbaren Gemischs ohne Umlenkmittel durchführbar ist, und dabei der Querschnitt der Auslaßöffnung der Hydromassagedüse einen möglichst kleinen Querschnitt aufweist.Another object of the invention is to design a hydromassage nozzle in such a way that the orientation of the mixture which can be expelled from the mouth of the mouth without deflecting means is feasible, and the cross section of the outlet opening of the hydromassage nozzle one has the smallest possible cross section.

Nicht zuletzt besteht die Aufgabe der Erfindung darin, eine Hydromassagedüse derart auszubilden, daß die Orientierung der aus der Düsenmündung ausstoßbaren Medien zwischen einer im wesentlichen axial gerichteten Strahlströmung und einer von der axialen Richtung divergierenden Strömung variierbar, vorzugsweise kontinuierlich zwischen im wesentlichen axialen und divergierenden Orientierung veränderbar ist.Last but not least, the object of the invention is to design a hydromassage nozzle in such a way that the orientation of the media that can be ejected from the nozzle mouth between an im essentially axially directed jet flow and a diverging from the axial direction Flow variable, preferably continuously between essentially axial and divergent orientation is changeable.

Gelöst wird diese Aufgabe durch eine Hydromassagedüse mit den Merkmalen gemäß Anspruch 1. Der Innenraum ist vorzugsweise kreiszylindrisch ausgebildet. Im wesentlichen ist der Innenraum zwischen zwei sich gegenüberliegenden, vorzugsweise flachen seitlichen Begrenzungswandungen und einer radial, rund bis spiralförmig umlaufenden Begrenzungswand ausgebildet ist, wobei von radial außen, vorzugsweise in den Bereich des größten Querschnitts des Innenraums des Düsengehäuses, in jedem Falle tangential, wenigstens ein erster Fluid-Versorgungskanal mündet, welcher Fluid-Versorgungskanal von außen mit einem druckbeaufschlagten flüssigen Medium versorgbar ist, wobei eine der seitlichen Begrenzungswandungen in ihrem Zentrum eine Wirbelkammer-Auslaßöffnung aufweist und ein zweiter, mit einem flüssigen oder gasförmigen Medium beaufschlagbaren Fluid-Versorgungskanal vorgesehen ist, der von außen in die Wirbelkammer hineinführt und mit seiner Umwandung die Wirbelkammer im wesentlichen axial durchsetzt und im wesentlichen auf der Höhe der Wirbelkammer-Auslaßöffnung mit einer zentralen Auslaßöffnung mündet, wobei zwischen der Umfassungswand des zweiten Fluid-Versorgungskanals und der Wirbelkammer-Auslaßöffnung In der einen seitlichen Begrenzungswand ein freier Ringspalt ausgebildet ist.This object is achieved by a hydromassage nozzle with the features according to claim 1. The interior is preferably circular cylindrical educated. The interior is essentially between two opposing, preferably flat lateral boundary walls and one radial, round to spiral circumferential boundary wall is formed, from radially outside, preferably in the Area of the largest cross section of the interior of the nozzle housing, in any case tangential, at least one first fluid supply channel opens, which fluid supply channel from the outside can be supplied with a pressurized liquid medium, one of the side Boundary walls in its center has a vortex chamber outlet opening and a second fluid supply channel which can be acted upon with a liquid or gaseous medium is provided, which leads from the outside into the swirl chamber and with its conversion Vortex chamber essentially penetrates axially and essentially at the level of Vortex chamber outlet opening with a central outlet opening, being between the Boundary wall of the second fluid supply channel and the swirl chamber outlet opening In one side boundary wall is formed a free annular gap.

Die Ausgestaltung hat den Vorteil, daß bei Versorgung mit druckbeaufschlagtem flüssigen Medium innerhalb der Wirbelkammer die Stromfäden der Strömung von radial tangential außen nach zentral innen verlaufen und dabei relativ zu der tangentialen Mündung des Versorgungskanals im Bereich der zentral innen angeordneten Wirbelkammer-Auslaßöffnung eine negative Druckzone erzeugbar ist und demzufolge das an dem Ringspalt in den Wanneninnenraum abgebbare flüssige Medium eine nach radial außen divergierende Orientierung einnimmt. Wird dann noch der zweite zentral angeordnete belüftbare Fluid-Versorgungskanal belüftet, so ist dem nach radial außen abgebbaren flüssigen Medium ein gasförmiges Medium zumischbar.The design has the advantage that when supplying pressurized liquid medium within the vortex chamber the flow threads of the flow from radially tangential outside to central run inside and relative to the tangential mouth of the supply channel in the area a negative pressure zone can be generated in the centrally located swirl chamber outlet opening and consequently the liquid medium that can be dispensed into the interior of the tub at the annular gap assumes a radially divergent orientation. Then the second becomes central arranged ventilated fluid supply channel is ventilated, so that is radially outward a gaseous medium can be added to the liquid medium.

Durch die divergierende Orientierung des aus dem Ringspalt abgebbaren Mediums ist in dem im Wasserbeckeninnenraum vorhandenen Wasser eine starke Sekundärströmung erzeugbar.Due to the divergent orientation of the medium that can be dispensed from the annular gap, in the Water pool interior existing water can generate a strong secondary flow.

Die Ausgestaltung hat den Vorteil, daß die divergierende Orientierung des aus dem Ringspalt abgebbaren Mediums ohne Umlenkmittel erfolgt. Die Ausgestaltung hat im weiteren den Vorteil, daß durch Beeinflussung der Sekundärströmung der Grad der Divergenz beeinflußbar ist. Sobald ein Badegast mit seinem Körper in den Bereich der Sekundärströmung eintaucht, wandelt sich die divergierende Orientierung zunehmend in eine auf den Körper des Badegasts gerichtete Orientierung und umgekehrt.The design has the advantage that the diverging orientation of the annular gap dispensable medium without deflecting means. The design has the further advantage that the degree of divergence can be influenced by influencing the secondary flow. Once a Bathers dip their bodies into the area of the secondary flow, which changes diverging orientation increasingly into one directed towards the body of the bathing guest Orientation and vice versa.

Die Ausgestaltung hat insbesondere den Vorteil, daß Hydromassagedüsen gemäß der Erfindung in solchen Bereichen des Wasserbeckens angeordnet werden können, die der Rückenpartie eines Badegastes, also im Berech des Wannenbodens und der Rückenlehne, zugeordnet sind, wobei bei Näherung des Körpers des Badegastes das aus der Hydromassagedüse abgebbare Medium eine abnehmend divergierend -also auf den Körper des Badegastes gerichtete- Orientierung einnimmt und eine zonenbezogene Unterwassermassage erfolgt, während die aus anderen, nicht im Näherungsbereich vorgesehenen Hydromassagedüsen, abgebbaren Medien weiterhin eine divergierende Orientierung beibehalten und der allgemeinen Belüftung des Badewassers dienen.The design has the particular advantage that hydromassage jets according to the invention in areas of the water basin can be arranged that the back of a Bathers, so in the calculation of the tub floor and the backrest, are assigned, with Approaching the body of the bather, the medium that can be dispensed from the hydromassage nozzle decreasing diverging - so oriented towards the body of the bathing guest and a zone-related underwater massage takes place while the other, not in the Hydromassage jets provided in the proximity range, dispensable media continue to be Maintain divergent orientation and serve the general ventilation of the bathing water.

Durch Annäherung an die Wirbelkammer-Auslaßöffnung ist die Orientierung der aus der Hydromassagedüse abgebbare Fluidmenge von divergierend nach zunehmend axial veränderbar.By approaching the swirl chamber outlet opening, the orientation is that of the The amount of fluid that can be dispensed from the hydromassage jet can be changed from diverging to increasingly axially.

Bei der Hydromassagedüse handelt es sich demnach um eine "intelligente" Hydromassagedüse, aus der dann eine im wesentlichen axial orientierte Strahlströmung abgebbar ist, wenn sich der Körper eines Badegastes der Wirbelkammer-Auslaßöffnung nähert und aus der dann eine im wesentlichen divergierende Fluidmenge abgebbar ist, wenn lediglich das sich in dem Wasserbecken befindliche Wasser durchströmt und belüftet werden soll. The hydromassage nozzle is therefore an "intelligent" hydromassage nozzle, from which then an essentially axially oriented jet flow can be emitted if the body is a Bather approaches the vortex chamber outlet and then essentially one divergent amount of fluid can be dispensed if only that in the water basin Water should be flowed through and aerated.

In einer Ausgestaltung weist die die Wirbelkammer Auslaßöffnung aufweisende seitliche Begrenzungswand der Wirbelkammer stromab des engsten Querschnitts der Auslaß-Öffnung eine konische, sich radial erweiternde Ausbildung auf.In one configuration, the lateral opening having the swirl chamber has an outlet opening Boundary wall of the swirl chamber downstream of the narrowest cross section of the outlet opening one conical, radially expanding formation.

Die Erfindung wird weiter dadurch verbessert, wenn über den zweiten Fluid-Versorgungskanal in das Zentrum der negativen Druckzone ein mit positivem Druck beaufschlagtes gasförmiges oder flüssiges Medium zuführbar ist. Diese Ausgestaltung hat den Vorteil, daß infolge von Ausgleich des negativen Drucks das aus der Wirbelkammer-Auslaßöffnung abgebbare flüssige Medium eine im wesentlichen axial gerichtete Orientierung einnimmt.The invention is further improved if in via the second fluid supply channel the center of the negative pressure zone is a gaseous or pressurized with positive pressure liquid medium can be supplied. This configuration has the advantage that as a result of compensation of the negative pressure, the liquid medium that can be dispensed from the swirl chamber outlet opening is an essentially axially oriented.

Wird der zweite Fluid-Versorgungskanal dabei von einem drucklufterzeugenden Gebläse versorgt, dann ist eine im wesentlichen axial gerichtete Strahlströmung und Gemischbildung erzielbar.If the second fluid supply channel is supplied by a compressed air generating fan, then an essentially axially directed jet flow and mixture formation can be achieved.

Der Einsatz der Hydromassagedüse kann erweitert werden, wenn der zweite Fluid-Versorgungskanal mit einem Fluid versorgbar ist, das wechselweise mit positivem und negativem Druck beaufschlagbar ist und die Druckdifferenz zwischen zwei Maximalwerten (+ -) variierbar ist. Vorzugsweise ist der zweite Fluid- Versorgungskanal durch ein in seiner Leistung stetig veränderbares drucklufterzeugendes Gebläse versorgbar. Es ist jedoch auch denkbar daß die Druckluftzuführung durch ein in der Versorgungsleitung vorgesehenes Steuerventil unterbrechbar ausgebildet ist und in zeitlich vorgebbaren Takten einmal Druckluft (Überdruck, positiv) und einmal Saugluft (Unterdruck, negativ) dem zweiten Versorgungskanal zuführbar ist.The use of the hydromassage nozzle can be expanded if the second fluid supply channel is included a fluid can be supplied, which can be acted upon alternately with positive and negative pressure and the pressure difference between two maximum values (+ -) is variable. Preferably, the second fluid supply channel through a continuously changing in its performance compressed air generating blower can be supplied. However, it is also conceivable that the compressed air supply is designed to be interruptible by a control valve provided in the supply line and in Time-definable cycles, once compressed air (positive pressure, positive) and once suction air (negative pressure, negative) can be fed to the second supply channel.

Die Ausgestaltung hat den Vorteil, daß die aus der Wirbelkammer-Auslaßöffnung abgebbare Fluidmenge stetig zwischen einer divergierenden und einer im wesentlichen axial gerichteten Orientierung veränderbar ist und daß über vorgesehene Steuermittel die Belüftung des zweiten Fluid-Versorgungskanals derart beeinflußbar ist, daß die Orientierung der aus der Hydromassagedüse abgebbaren Fluidmenge zwischen divergierend oder im wesentlichen axial gerichtet wählbar ist.The configuration has the advantage that the dispensable from the swirl chamber outlet opening Fluid amount steadily between a divergent and a substantially axially directed Orientation is changeable and that the ventilation of the second is provided via the control means provided Fluid supply channel can be influenced such that the orientation of the Hydromassage nozzle deliverable amount of fluid between diverging or substantially axial is selectable.

Die Veränderbarkeit der Orientierung ist gemäß der Erfindung auch dadurch erreichbar, indem dem zweiten Fluid-Versorgungskanal zumindest eine Teilmenge von flüssigem Medium zugeführt wird. In einer bevorzugten Ausgestaltung ist vorgesehen, an den mit flüssigem Medium beaufschlagbaren Kanal- oder Bereich des Düsengehäuses einen Verbindungs-Strömungskanal derart anzuschließen, daß zwischen dem erstgenannten Bereich und dem mit gasförmigem Medium versorgbaren zweiten Versorgungkanal eine Strömungsverbindung herstellbar ist und in den mit gasförmigem Medium versorgbaren Fiuid-Versorgungskanal flüssiges Medium einbringbar ist. Vorzugsweise ist in den Verbindungs-Strömungskanal ein Regelventil, vorzugsweise ein Magnetventil, eingeschaltet, welches Regelventil in eine Öffungsstellung und in eine Schließstellung steuerbar ist, wobei während der Zeitdauer der Öffnung des Regelventils eine Teilmenge von flüssigem Medium in den mit gasförmigem Medium beaufschlagbaren zweiten Fluid Versorgungskanal einbringbar ist.According to the invention, the changeability of the orientation can also be achieved by the second fluid supply channel is supplied at least a subset of liquid medium. In a preferred embodiment it is provided that liquid medium can be applied to it Channel or area of the nozzle housing such a connection flow channel to connect that between the former and the gaseous medium supplyable second supply channel a flow connection can be established and in the Fiuid supply channel liquid medium can be introduced into gaseous medium. A control valve, preferably a, is preferably in the connecting flow channel Solenoid valve, switched on, which control valve in an open position and in a closed position is controllable, a subset of during the period of opening of the control valve liquid medium in the second fluid to which gaseous medium can be applied Supply channel can be introduced.

Vorteilhaft ist es, innerhalb des zweiten Fluid-Versorgungskanals, koaxial zu dessen Innenwandungen, in Strömungsrichtung verlaufend, ein Strahlrohr anzuordnen, welches Strahlrohr innerhalb des zweiten Fluid-Versorgungskanals mit einer Auslaßöffnung endet, durch welches Strahlrohr flüssiges Medium, in Strömungsrichtung des gasförmigen Mediums, in den zweiten Fluid-Versorgungskanal einbringbar ist.It is advantageous to coaxial to the second fluid supply channel Inner walls, running in the direction of flow, to arrange a jet pipe, which jet pipe ends within the second fluid supply channel with an outlet opening through which Jet pipe liquid medium, in the direction of flow of the gaseous medium, in the second fluid supply channel can be introduced.

In einer vorteilhaften Ausgestaltung weist die Wirbelkammer zwischen ihren seitlichen Begrenzungswandungen angeordnete Lenkmittel auf, durch welche Lenkmittel der Verlauf der Fluid-Stromfäden beeinflußbar ist. Die Lenkmittel sind auf einem die Wirbelkammer unterteilenden Umkreis derart angeordnet, daß die radiale Ebene der Wirbelkammer in zwei Teilbereiche unterteilt ist. Wobei ein Wirbelkammer-Teilbereich radial außen der Lenkmittel einen Ringkanal bildet und der andere Wirbelkammer-Teilbereich zentral innen die Umfassungswand des zweiten Fluid-Versorgungskanal und die Wirbelkammer-Auslaßöffnung mit Abstand umschließt. Die Lenkmittel sind mit Fluid-Durchtrittsöffnungen versehen und derart ausgebildet, daß Fluid von dem als Ringkanal ausgebildeten ersten Wirbelkammer-Teilbereich in den die Wirbelkammer-Ausiaßöffnung und die Umfassungswand des zweiten Fluid-Versorgungskanals umschließenden zweiten Wirbelkammer-Teilbereich einleitbar ist. Die an dem Lenkmittel ausgebildeten Durchtrittsöffnungen weisen bevorzugt, relativ zu der Wirbelkammer-Auslaßöffnung tangential gerichtete Durchtrittsöffnungen auf, welche Durchtrittsöffnungen in den zweiten Wirbelkammer-Teilbereich münden.In an advantageous embodiment, the swirl chamber has between its lateral Boundary walls arranged steering means through which steering means the course of the Fluid flow threads can be influenced. The steering means are on a dividing the swirl chamber Perimeter arranged such that the radial plane of the swirl chamber is divided into two parts is. A swirl chamber section radially outside the steering means forms an annular channel and the other vortex chamber sub-area centrally inside the peripheral wall of the second fluid supply channel and encloses the vortex chamber outlet opening at a distance. The steering means are provided with fluid passage openings and are designed such that fluid from the Ring channel formed first swirl chamber portion in the swirl chamber outlet and enclosing the peripheral wall of the second fluid supply channel second vortex chamber section can be introduced. The trained on the steering means Through openings preferably point tangentially relative to the swirl chamber outlet opening directed through openings, which through openings in the second swirl chamber sub-area lead.

Diese Ausgestaltung hat den Vorteil, daß die Stromfäden der über den ersten Fluid-Versorgungskanal zuführbaren Fluidmenge, innerhalb der Wirbelkammer, auf von radial außen nach zentral innen verlaufenden Spiralbahnen lenkbar sind.This embodiment has the advantage that the current threads flow through the first fluid supply channel amount of fluid that can be supplied, inside the swirl chamber, from radially outside to centrally running spiral tracks are steerable.

Als Lenkmittel können auch Leitrippen dienen, welche zwischen den seitlichen Wandungen der Wirbelkammer vorgesehen sind, wobei zwischen verschiedenen Leitrippen jeweils ein Strömungskanal ausgebildet ist, welche Strömungskanäle von dem als Ringkanal ausgebildeten ersten Teilbereich der Wirbelkammer mit Fluid versorgbar sind. Die Strömungskanäle münden in den die Wirbelkammer-Auslaßmündung umfassenden zweiten Teil der Wirbelkammer ein, wie vorausgehend beschrieben.Guide ribs, which are located between the side walls of the Vortex chamber are provided, each between different guide ribs Flow channel is formed, which flow channels from the one designed as an annular channel the first section of the swirl chamber can be supplied with fluid. The flow channels open into the second part of the swirl chamber comprising the swirl chamber outlet mouth, such as previously described.

In einer bevorzugten Variante ist der Kreiskegel(stumpf) über vorgesehene Mittel axial in seiner Lage veränderbar und bewegbar, vorzugsweise durch den Druck des strömenden Mediums gegen einen Federkraftspeicher bewegbar, ausgebildet. Dabei ist es vorteilhaft, den Kreiskegel(stumpf) mit Betätigungsmitteln zu versehen und diesen verdrehbar oder axial verschiebbar derart auszubilden, daß dieser mit seiner Kegelspitze(Kegelstumpf) in bis an die Mündung des zweiten Versorgungskanals heranführbar, jedoch auch wieder ausbringbar ist. Durch diese Ausgestaltung ist der Querschnitt der Wirbelkammer-Austrittsöffnung veränderbar.In the development of the hydromassage nozzle, the annular gap between the Boundary wall of the second fluid supply channel and that in the side Boundary wall of the vortex chamber or the vortex chamber outlet opening provided there is designed to assign a circular cone, at least one circular truncated cone, that with Distance between the wall of the circular cone (truncated cone) and that in the side Boundary wall of the swirl chamber on which the swirl chamber outlet opening is formed, forms an annular gap channel running radially outwards. In a preferred variant, the Circular cone (blunt) can be axially changed and moved in its position by means provided, preferably by the pressure of the flowing medium against a spring force accumulator movable, trained. It is advantageous to close the circular cone (blunt) with actuating means provided and this rotatable or axially displaceable in such a way that this with his Cone tip (truncated cone) can be brought up to the mouth of the second supply channel, but can also be deployed again. Due to this configuration, the cross section of the Eddy chamber outlet opening changeable.

In einer zweiten Variante der Hydromassagedüse ist vorgesehen die Wirbelkammer derart auszubilden, daß neben dem ersten Fluid-Versorgungskanal für ein flüssiges Medium und dem zweiten Fluid-Versorgungskanal für ein gasförmiges und/oder flüssiges Medium ein dritter Fluid-Versorgungskanal für die Zuführung eines Steuermediums vorgesehen ist.In a second variant of the hydromassage nozzle, the swirl chamber is designed in such a way that in addition to the first fluid supply channel for a liquid medium and the second fluid supply channel a third fluid supply channel for a gaseous and / or liquid medium is provided for the supply of a control medium.

Der dritte Versorgungskanal ist von außen mit einem flüssigen Medium versorgbar und mündet vorzugsweise im mittleren Bereich einer der seitlichen Begrenzungswände tangential in die Wirbelkammer ein. Bei dieser Ausgestaltung ist es denkbar, den ersten Versorgungskanal radial oder seitlich in die Wirbelkammer einzuführen.The third supply channel can be supplied with a liquid medium from the outside and opens out preferably in the central region of one of the lateral boundary walls tangentially into the Vortex chamber. With this configuration, it is conceivable for the first supply channel to be radial or insert laterally into the swirl chamber.

Diese Ausgestaltung hat den Vorteil, daß bei Versorgung der Wirbelkammer durch den ersten Fluid-Versorgungskanal, mit einem flüssigen Medium, eine im wesentlichen axial gerichtete Orientierung des aus der Auslaßöffnung abgebbaren Fluids erzielbar ist. Daß bei Versorgung der Wirbelkammer durch den dritten Fluid-Versorgungskanal, mit einem flüssigen Medium, eine im wesentlichen divergierende Orientierung des aus der Auslaßöffnung abgebbaren Fluids erzielbar ist.This embodiment has the advantage that when the swirl chamber is supplied by the first fluid supply channel, with a liquid medium, an essentially axially oriented orientation of the fluid dispensable from the outlet opening can be achieved. That when supplying the vertebral chamber through the third fluid supply channel, with a liquid medium, essentially one divergent orientation of the fluid dispensable from the outlet opening can be achieved.

Die Vorteile der Hydromassagedüse sind erweiterbar, wenn der erste Fluid-Versorgungskanal und der dritte Fluid-Versorgungskanal an eine gemeinsamme Quelle angeschlossen werden und ein Regel- und Absperrmittel, (wie z.B. ein Dreiwegeventil) das zwischen zwei den jeweiligen Fluid-Strömungsweg festlegenden Schaltstellungen und beliebigen Zwischenstellungen betätigbar ist, in die zu den Versorgungskanälen hinführenden Leitungsabschnitte derart eingeschaltet ist, daß bei Betätigung des Regel- und Absperrmittels in der einen Schaltstellung der erste Fluid-Versorgungskanal und in der zweiten Schaltstellung der dritte Fluid-Versorgungskanal mit flüssigem Medium versorgbar ist. Vorzugsweise ist das Regel- und Abspermittel zwischen der ersten und der zweiten Schaltstellung in jede gewünschte Zwischenstellung betätigbar, sodaß entsprechend der jeweils wählbaren Zwischenstellung der erste Fluid-Versorgungskanal und der dritte Fluid-Versorgungskanal gemeinsam, mit gleichen oder unterschiedlichen Fluidmengen versorgbar sind. Bei dieser Ausgestaltung sind durch das über die dritte Fluid-Versorgungsleitung zuführbare und aus der Mündungsöffnung 32 abgebbare Medium tangentiale Steuereinflüsse auf das durch den ersten Fluid-Versorgungskanal in zugeführte Medium abgebbar, wodurch das Medium in Rotationsbewegung versetzbar ist.The benefits of the hydromassage nozzle are expandable if the first fluid supply channel and the third Fluid supply channel can be connected to a common source and a control and Shut-off means (such as a three-way valve) between two the respective fluid flow path defining switch positions and any intermediate positions can be actuated in the Supply channels leading line sections is turned on such that when actuated of the control and shut-off means in the one switching position, the first fluid supply channel and in In the second switching position, the third fluid supply channel can be supplied with liquid medium. The regulating and releasing means is preferably between the first and the second switching position can be actuated in any desired intermediate position, so that it can be selected according to the particular one Intermediate position of the first fluid supply channel and the third fluid supply channel can be supplied together with the same or different amounts of fluid.

When supplying the first fluid supply channel a substantial amount of fluid from the vortex chamber outlet axially directed orientation can be output and when supplying the third fluid supply channel a substantially divergent orientation from the swirl chamber outlet deliverable amount of fluid can be achieved.

Als Regel- und Absperrmittel können ebenso Magnetventile dienen, ebenso kann zur Betätigung des Regel- und Absperrmittel ein Servomotor vorgesehen sein. Der Komfort der erfindungsgemäßen Vorrichtung wird im weiteren dadurch gesteigert, wenn elektronische Mittel vorgesehen sind, durch welche das Regel- und Absperrmittel beeinflußbar und steuerbar ist.Solenoid valves can also serve as control and shut-off means, as can actuation of the control and shut-off means, a servo motor can be provided.

Der Verteiler weist neben einem Versorgungsanschluß kopfseitig eine Deckplatte und dazwischen liegend eine Hohlkammer auf. Radial der Hohlkammer sind umlaufend mehrere Fluid-Austrittsöffnungen vorgesehen, welche Fluid-Austrittsöffnungen tangential zu der radialen Begrenzungswand der Wirbelkammer angeordnet sind, aus welchen Fluid-Austrittsöffnungen fluidische radiale oder radial-tangentiale Steuereinflüsse auf das durch den ersten Versorgungskanal 9 zuführbare Medium abgebbar sind.In a further variant of the hydromassage nozzle, a distributor is provided within the swirl chamber to provide which distributor from the third fluid supply channel with liquid medium is available.

Bei Versorgung der Wirbelkammer durch den ersten Fluid-Versorgungskanal, mit einem flüssigen Medium, ist eine im wesentlichen axial gerichtete Orientierung des aus der Wirbelkammer-Auslaßöffnung abgebbaren Fluidmenge erzielbar. Bei Versorgung der Wirbelkammer durch den dritten Fluid-Versorgungskanal mit einem flüssigen Medium, ist eine im wesentlichen divergierende Orientierung des aus der Auslaßöffnung abgebbaren Fluids erzielbar.When the swirl chamber is supplied with a liquid through the first fluid supply channel Medium, is a generally axially oriented orientation of the outlet from the swirl chamber deliverable amount of fluid achievable. When the swirl chamber is supplied by the third fluid supply channel with a liquid medium, is a substantially divergent Orientation of the fluid dispensable from the outlet opening can be achieved.
