Es sind eine Vielzahl von Sprühköpfen und Vorrichtungen bekannt, bei denen die Sprühcharakteristik verstellbar ist. Bisher läßt sich grundsätzlich zwischen zwei Arten unterscheiden.There are a variety of spray heads and devices are known in which the spray characteristic is adjustable. So far, basically two types can be distinguished.

Bei der ersten Art wird über eine der Düse vorgeschaltete, verstellbare Drossel die .Ausbrxngrate - also der Volumen- bzw. Massenstrom - variiert, wodurch entsprechend die Sprühcharakteristik beeinflußbar und einstellbar ist. Nachteilig ist hierbei, daß die Sprühcharakteristik, insbesondere der Sprühwinkel nicht optimal einstellbar ist. Bei der zweiten Art sind verschiedene Düsen vorgesehen, die unterschiedliche Sprühcharakteristiken aufweisen und zwischen denen die Ausgabe umschaltbar ist. Nachteilig ist hierbei, daß der konstruktive Aufwand relativ groß ist und die verschiedenen Düsen teilweise eine beträchtliche Baugröße erfordern.In the first type, the adjustable outlet throttle, ie the volume or mass flow, is varied via an adjustable throttle upstream of the nozzle, as a result of which the spray characteristic can be influenced and adjusted accordingly. The disadvantage here is that the spray characteristics, in particular the spray angle is not optimally adjustable. In the second type, various nozzles are provided which have different spray characteristics and between which the output is switchable. The disadvantage here is that the design effort is relatively large and the different nozzles sometimes require a considerable size.

Jedoch sind hier auch andere konstruktive Lösungen oder Betätigungsmechanismen einsetzbar. Dies gilt insbesondere, wenn der Sprühköpf 5 beispielsweise bei einem Dispenser, einer Pumpe o. dgl. eingesetzt wird.In the illustrated example, the actuation or opening of the valve 4 is preferably carried out by depressing the actuating element 11 and thus the output channel 6 or connector 7 to actuate the valve element 8, in particular depressing and thereby open the valve 4.

Der Sprühkopf 5 bzw. die Düsenanordnung 9 weist beim Darstellungsbeispiel vorzugsweise nur eine einzige Düse 15 und ein zugeordnetes Stellelement 16 zur Einstellung der Sprühcharakteristik des Sprühkopfs 5 bzw. der Düsenanordnung 9 auf.In the illustrated embodiment, the spray head 5 or the nozzle arrangement 9 preferably has only a single nozzle 15 and an associated adjusting element 16 for adjusting the spray characteristic of the spray head 5 or the nozzle arrangement 9.

Die Düse 15 schließt sich beim Darstellungsbeispiel an den Ausgabekanal 6 an.

Das Düsenelement 17 ist vorzugsweise separat hergestellt und dann in eine entsprechende Aufnahmekammer bzw. den Ausgabekanal 6 eingesetzt. Jedoch sind hier auch andere konstruktive Lösungen möglich.The nozzle 15 adjoins the output channel 6 in the illustrated example. The nozzle 15 is formed, in particular, by a nozzle element 17 built into or connected to the dispensing channel 6. The nozzle element 17 is preferably manufactured separately and then inserted into a corresponding receiving chamber or the output channel 6. However, other constructive solutions are possible here.

Die Düse 15 bzw. deren Düsenelement 17 bildet eine Düsenkammer 18 und weist abgabeseitig eine Düsenöffnung 19 auf. Insbesondere verjüngt sich die Düsenkammer 18 zur Düsenöffnung 19 hin, vorzugsweise konisch.The nozzle 15 or its nozzle element 17 forms a nozzle chamber 18 and has a nozzle opening 19 on the discharge side. In particular, the nozzle chamber 18 tapers toward the nozzle opening 19, preferably conically.

Die Düsenkammer 18 bildet eine Wirbelkammer der Düse 15 bzw. des Sprühkopfs 5. Eine gezielte Wirbelbildung kann durch entsprechende, insbesondere mit tangentialer Komponente in die Düsenkammer 18 einmündende Zulaufkanäle 20 erreicht werden, die sich insbesondere auch etwas radial zur Düsenöffnung 19 hin erstrecken und in Fig. 1 nur angedeutet sind.A targeted vortex formation can be achieved by appropriate, especially with tangential component in the nozzle chamber 18 opening feed channels 20 which extend in particular also somewhat radially to the nozzle opening 19 out and in Fig. 1 are only indicated.

Das Stellelement 16 schließt sich abgabeseitig an die Düse 15 bzw. Düsenöffnung 19 an und/oder überdeckt diese.The adjusting element 16 closes on the discharge side to the nozzle 15 or nozzle opening 19 and / or covers them.

Die der Düsenöffnung 19 nachgeordnete Auslassöffnung 13 ist im Stellelement 16 gebildet. Zur Einstellung der Sprühcharakteristik weist das Stellelement 16 beim Darstellungsbeispiel mehrere Auslassöffnungen 13 mit unterschiedlichen Sprühcharakteristiken auf. Die Auslassöffnungen 13 unterscheiden sich insbesondere hinsichtlich ihres Durchmessers und/oder ihrer Länge. Die Auslassöffnungen 13 sind insbesondere als Durchlassbohrungen bzw. zylindrisch ausgebildet. Jedoch sind hier auch andere konstruktive Lösungen möglich.The nozzle opening 19 downstream outlet opening 13 is formed in the control element 16. In order to set the spray characteristic, the control element 16 in the illustrated example has a plurality of outlet openings 13 with different spray characteristics. The outlet openings 13 differ in particular with regard to their diameter and / or their length. The outlet openings 13 are in particular as through-holes or cylindrical educated. However, other constructive solutions are possible here.

Die Auslaßöffnungen 13 sind wahlweise vor die Düsenöffnung 19 bringbar. Hierzu ist das Stellelement 16 entsprechend relativ zur Düse 15 bzw. deren Düsenöffnung 19 verstellbar, insbesondere drehbar. Jedoch kann auch umgekehrt die Düse 15 bewegbar, insbesondere drehbar, sein, um wahlweise eine der Auslaßöffnungen 13 vor der Düsenöffnung 19 anzuordnen.The outlet openings 13 are selectively engageable in front of the nozzle opening 19. For this purpose, the adjusting element 16 is correspondingly adjustable relative to the nozzle 15 and the nozzle opening 19, in particular rotatable. However, conversely, the nozzle 15 may be movable, in particular rotatable, to selectively arrange one of the outlet openings 13 in front of the nozzle opening 19.

Die Auslaßöffnung 13 beeinflußt die Sprühcharakteristik des Sprühkopfs 5 bzw. der Düsenanordnung 9 maßgeblich. Insbesondere ist ein Sprühwinkel 21 des Sprühnebels 10 bzw. eines Sprühstrahls durch die Wahl der entsprechenden Auslaßöffnung 13 - also durch die Drehstellung des Stellelements 16 - variierbar bzw. einstellbar.The outlet opening 13 influences the spray characteristics of the spray head 5 and the nozzle assembly 9 significantly. In particular, a spray angle 21 of the spray 10 or a spray jet by the choice of the corresponding outlet opening 13 - ie by the rotational position of the actuating element 16 - variable or adjustable.

Vorzugsweise erfolgt eine Trennung der Düsenanordnung 9 in die die Wirbelkammer enthaltende bzw. bildende (stationäre und/oder gemeinsame) Düse 15 und die nachgeordnete, zur Einstellung der Sprühcharakteristik veränderbare bzw. wählbare (wechselbare bzw. bewegbare) Auslaßöffnung 13. Insbesondere kann die Auslaßöffnung 13 bzw. das Stellelement 16 auch als verstellbare bzw. wechselbare Blende zur Festlegung der jeweils gewünschten Sprühcharakteristik des Sprühkopfs 5 bzw. der Düsenanordnung 9 verstanden werden.Preferably, a separation of the nozzle assembly 9 in the vortex chamber containing or forming (stationary and / or common) nozzle 15 and the downstream, adjustable to adjust the spray characteristic or selectable (removable or movable) outlet opening 13 is carried out in particular, the outlet opening 13th or the adjusting element 16 can also be understood as an adjustable or exchangeable diaphragm for determining the respectively desired spray characteristic of the spray head 5 or the nozzle arrangement 9.

By turning or depending on the position of the adjusting element 16 is optionally one of the outlet openings 13 to the nozzle 15 and the nozzle opening 19 fluidly connected.

Dem schematischen Horizontalschnitt des Sprühkopfs 5 gemäß Fig. 2 ist zu entnehmen, daß die Auslaßöffnungen 13 vorzugsweise in Umfangsrichtung beabstandet am Sprühkopf 5 bzw. Stellelement 16 angeordnet sind. Je nach Drehstellung des Stellelements 16 befindet sich dann eine Auslaßöffnung 13 vor der Düse 15 bzw. Düsenöffnung 19. Wahlweise kann die Düse 15 bzw. Düsenöffnung 19 auch ganz durch das Stellelement 16 verschließbar sein.The schematic horizontal section of the spray head 5 according to Fig. 2 It can be seen that the outlet openings 13 are preferably arranged circumferentially spaced on the spray head 5 and actuator 16. Depending on the rotational position of the adjusting element 16 is then an outlet opening 13 in front of the nozzle 15 and nozzle opening 19. Alternatively, the nozzle 15 or nozzle opening 19 can be completely closed by the actuator 16.

Dar Stellelement 16 ist vorzugsweise rastend verstellbar. Der Sprühkopf 5 weist hierzu vorzugsweise eine entsprechende Rasteinrichtung auf. Beim Darstellungsbeispiel kann die Rasteinrichtung bspw. einen Vorsprung 22 aufweisen, der insbesondere auf der Innenseite des Stellelements 16 gebildet ist und nach innen radial vorspringt. Durch Eingriff in eine zugeordnete Vertiefung 23 beispielsweise an einer Lagerfläche, die das Stellelement 16 innenseitig führt und insbesondere vom Unterteil 14 gebildet ist, kann eine entsprechende Rasteinrichtung realisiert werden. Die Rasteinrichtung kann jedoch auch einem weiteren Zweck dienen, wie nachfolgend noch erläutert, oder auf sonstige Art und Weise gebildet werden.Dar actuator 16 is preferably latching adjustable. For this purpose, the spray head 5 preferably has a corresponding latching device. In the illustrated example, the latching device may, for example, have a projection 22, which is formed in particular on the inside of the adjusting element 16 and projects radially inwards. By engaging in an associated recess 23, for example, on a bearing surface, which guides the adjusting element 16 on the inside and is in particular formed by the lower part 14, a corresponding latching device can be realized. However, the locking device can also serve a further purpose, as explained below, or be formed in any other way.

This can be done for example by appropriate shaping and / or dimensioning of the adjusting element 16 relative to the lower part 14, the nozzle 15 and / or other components of the spray head 5 and / or the inner surface 24 to the outer surface 25. In particular, in this case an elastic deformation or deformability of parts, projections o. The like. Considered or exploited.

Insbesondere ist das Stellelement 16 aus einem flexibleren und/oder weicheren Material als das Unterteil 14 oder sonstige Komponenten des Sprühkopfs 5 hergestellt, um eine definierte elastische Verformung beispielsweise beim Umschalten von einer Auslaßöffnung 13 auf eine andere Auslaßöffnung 13, zum Einrasten in der jeweiligen Stellung und/oder zur Erzielung einer gewünschten Abdichtung auszunutzen.In particular, the actuator 16 is made of a more flexible and / or softer material than the lower part 14 or other components of the spray head 5 to a defined elastic deformation, for example when switching from one outlet opening 13 to another outlet opening 13, for locking in the respective position and / or exploit to achieve a desired seal.

Gemäß einer besonders bevorzugten Ausführungsvariante wird das Vorspannen bzw. die Vorspanneinrichtung dadurch realisiert, daß das Stellelement 16 auf der der Düse 15 gegenüberliegenden Seite radial nach außen gespannt wird (dies kann insbesondere durch mindestens einen Vorsprung 22 erreicht werden, der beispielsweise auf einer etwa tangential verlaufenden Gleitfläche bzw. Verdickung 26 nach außen geführt wird), um das Stellelement 16 peripher bzw. über seinen Umfang zu spannen und so mit seiner Innenfläche 24 gegen die Düse 15 zu drücken, insbesondere um die Abdichtung zwischen Düse 15 und Stellelement 16 bzw. zwischen Düsenöffnung 19 und Auslaßöffnung 13 zu erreichen oder zu verbessern. Insbesondere ist es so möglich, daß beim Drehen des Stellelements 16 der der Düse 15 zumindest im wesentlichen gegenüberliegende Vorsprung 22 auf der Gleitfläche 26 radial nach außen gedrängt wird, wodurch das Stellelement 16 entsprechend im Bereich der Düse 15 stärker gegen diese gespannt wird. Erst bei Erreichen der Enddrehstellung des Stellelements 16 (in dieser Endstellung liegt die gewünschte Auslaßöffnung 13 vor der Düse 15 bzw. deren Düsenöffnung 19), kann der genannte Vorsprung 22 in die optional vorgesehene Vertiefung 23 in der Gleitfläche 26 eingreifen, wodurch die gewünschte Rastwirkung bzw. Rasteinrichtung realisiert werden kann.According to a particularly preferred embodiment, the biasing or the biasing means is realized in that the adjusting element 16 is stretched on the opposite side of the nozzle 15 radially outward (this can be achieved in particular by at least one projection 22, for example, on an approximately tangentially extending Sliding surface or thickening 26 is guided to the outside) to clamp the actuator 16 peripherally or over its circumference and press so with its inner surface 24 against the nozzle 15, in particular to the seal between the nozzle 15 and actuator 16 and between the nozzle opening 19 and outlet 13 to achieve or improve. In particular, it is possible that upon rotation of the actuating element 16 of the nozzle 15 at least substantially opposite projection 22 is urged radially outward on the sliding surface 26, whereby the adjusting element 16 is accordingly clamped in the region of the nozzle 15 more against this. Only when reaching the final rotational position of the adjusting element 16 (in this end position is the desired outlet opening 13 in front of the nozzle 15 and the nozzle opening 19), the said Projection 22 engage in the optionally provided recess 23 in the sliding surface 26, whereby the desired locking action or latching device can be realized.

Zusätzlich oder alternativ stehen weitere Möglichkeiten des Vorspannens bzw. zur Realisierung der Vorspanneinrichtung zur Verfügung, die nachfolgend erläutert werden.Additionally or alternatively, other possibilities of preloading or for the realization of the pretensioner are available, which are explained below.

Gemäß einem zusätzlichen oder alternativen Aspekt der vorliegenden Erfindung kann der Sprühkopf 1 zur Realisierung der Vorspannung bzw. Vorspanneinrichtung eine schiefe Ebene 27 aufweisen, um beim Betätigen des Sprühkopfs 5, hier Niederdrücken des Betätigungselements 11 bzw. Stellelements 16, ein radiales Spannen des Stellelements 16 gegen die Düse 15 zu erreichen. Bei dem in Fig. 1 gezeigten Darstellungsbeispiel ist die schiefe Ebene 27 durch eine oder mehrere, vorzugsweise starre Rippen 28 gebildet. Die Rippen 28 sind vorzugsweise an das Unterteil 14 oder an eine sonstige Komponente des Sprühkopfs 5 angeformt.According to an additional or alternative aspect of the present invention, the spray head 1 to realize the biasing or biasing means have an inclined plane 27, to press the actuating element 11 and actuator 16, a radial clamping of the actuating element 16 against the actuation of the spray head 5 to reach the nozzle 15. At the in Fig. 1 shown illustration, the inclined plane 27 is formed by one or more, preferably rigid ribs 28. The ribs 28 are preferably formed on the lower part 14 or on another component of the spray head 5.

Die schiefe Ebene 27 ist vorzugsweise auf der der Düse 5 bzw. Düsenanordnung 9 gegenüberliegenden Seite angeordnet und/oder so ausgebildet, daß bei Niederdrücken des Stellelements 16 dieses durch Abgleiten auf der schiefen Ebene 17 radial nach außen verlagert und dadurch gegen die Düse 15 gespannt wird.The inclined plane 27 is preferably arranged on the nozzle 5 or nozzle assembly 9 opposite side and / or formed so that upon depression of the actuating element 16 this displaced by sliding on the inclined plane 17 radially outward and is thereby clamped against the nozzle 15 ,

Jedoch sind hier auch andere konstruktive Lösungen möglich, die nachfolgend anhand von Fig. 3 erläutert werden, die eine zweite Ausführungsform des vorschlagsgemäßen Sprühkopfs 5 in einem schematischen Vertikalschnitt zeigt. Nachfolgend werden nur wesentliche Unterschiede gegenüber der ersten Ausführungsform erläutert, so daß die bisherigen Ausführungen insbesondere ergänzend oder entsprechend gelten.However, other constructive solutions are possible here, which are described below with reference to Fig. 3 which shows a second embodiment of the proposed spray head 5 in a schematic vertical section. Only essential differences from the first embodiment will be explained below, so that the previous statements apply in particular supplementary or corresponding.

Bei der ersten Ausführungsform ist das Stellelement 16 vorzugsweise kappenartig bzw. als Abdeckung des Sprühkopfs 5 ausgebildet. vorzugsweise ist bei der ersten Ausführungsform das Stellelement 16 mit dem Betätigungselement 11 verbunden bzw. versehen. Bei der ersten, in Fig. 1 gezeigten Ausführungsform schließt sich an das Betätigungselement 11 vorzugsweise ein Betätigungsvorsprung 29 an, der bei Betätigung auf den Ausgabekanal 6 bzw. das Anschlußstück 7 drückt, also die Niederdrückbewegung überträgt.In the first embodiment, the adjusting element 16 is preferably designed like a cap or as a cover of the spray head 5. Preferably, in the first embodiment, the adjusting element 16 is connected or provided with the actuating element 11. At the first, in Fig. 1 shown embodiment, the actuating element 11 is preferably followed by an actuating projection 29, which presses on actuation of the output channel 6 and the connector 7, that transmits the depression movement.

Bei der zweiten, in Fig. 3 gezeigten Ausführungsform ist das Betätigungselement 11 getrennt vom Stellelement 11 gebildet, beispielsweise vom Unterteil 4 oder einem sonstigen Teil. Alternaiv oder zusätzlich ist der Betätigungsvorsprung 29 mit der schiefen Ebene 27 versehen, die insbesondere mit einer komplementär geneigten Abgleitfläche 30 am Abgabekanal 6 bzw. Anschlußstück 7 derart kooperiert, daß bei Betätigung bzw. Niederdrücken des Sprühkopfs 5, des Betätigungselements 11 bzw. Betätigungsvorsprungs 29 die schiefe Ebene 27 derart an der Abgleitfläche 30 tendenziell abgeleitet, daß der Abgabekanal 6 radial nach außen in Richtung der Düse 15 und damit zusammen mit der Düse 15 gegen das Stellelement 16 im Bereich der Innenfläche 24 - also gegen dessen Auslaßöffnung 13 - gespannt wird. In diesem Fall wird die Düse 15 entgegen das Stellelement 16 gespannt. Auch hierdurch läßt sich wiederum die gewünschte Abdichtung zwischen Düse 15 und Stellelement 16 erreichen oder zumindest verbessern.At the second, in Fig. 3 In the embodiment shown, the actuating element 11 is formed separately from the actuating element 11, for example from the lower part 4 or another part. Alternatively or additionally, the actuating projection 29 is provided with the inclined plane 27, which cooperates in particular with a complementary inclined sliding surface 30 on the discharge channel 6 or connector 7 such that upon actuation or depression of the spray head 5, the actuating element 11 or Betätigungsvorsprungs 29 the inclined plane 27 tends to be derived on the sliding surface 30, that the discharge channel 6 radially outward in the direction of the nozzle 15 and thus together with the nozzle 15 against the adjusting element 16 in the region of the inner surface 24 - that is against the outlet 13 - stretched. In this case, the nozzle 15 is tensioned against the adjusting element 16. This, in turn, can be achieved or at least improve the desired seal between the nozzle 15 and actuator 16 again.

Bei den beschriebenen Möglichkeiten zum Vorspannen bzw. zur Realisierung der Vorspanneinrichtung erfolgt das Vorspannen vorzugsweise nur während der Ausgabe der Flüssigkeit 2 bzw. Betätigung des Sprühkopfs 5. Jedoch ist es grundsätzlich auch möglich, das Stellelement 16 gegen die Düse 5 bzw. deren Düsenöffnung 9 oder umgekehrt nicht nur während der Betätigung des Sprühkopfs 5 bzw. der Ausgabe von Flüssigkeit 2, sondern auch darüber hinaus vorzuspannen. Dies kann - wie bereits erläutert - durch entsprechende Formgebung der Innenfläche 24 und Außenfläche 25 und/oder generelle Vorspannung des Stellelements 16 gegen die Düse 15 erreicht werden. Alternativ oder zusätzlich kann die Vorspanneinrichtung auch eine Feder 31 aufweisen oder dadurch gebildet sein, wie in Fig. 3 angedeutet.In the described possibilities for biasing or for the realization of the biasing device, the biasing is preferably only during the output of the liquid 2 or actuation of the spray head 5. However, it is also possible in principle, the actuator 16 against the nozzle 5 and the nozzle opening 9 or vice versa, not only during operation of the spray head 5 and the output of liquid 2, but also bias beyond. This can - as already explained - be achieved by appropriate shaping of the inner surface 24 and outer surface 25 and / or general bias of the actuating element 16 against the nozzle 15. Alternatively or additionally, the biasing means may also include or be formed by a spring 31, as in FIG Fig. 3 indicated.

Die Feder 31 spannt vorzugsweise den Abgabekanal 6 mit der Düse 15 oder ggf. nur die Düse 15 gegen das Stellelement 16. Die Feder 31 greift hierzu vorzugsweise auf der der Düse 15 abgewandten Seite am Anschlußstück 7 an. Am anderen Ende ist die Feder 31 beispielsweise an einem stationären Teil des Sprühkopfs 5, wie dem Unterteil 14, oder beispielsweise am Stellelement 16 oder einer sonstigen Abdeckkappe oder einem sonstigen Betätigungselement des Sprühkopfs 5 abgestützt. Jedoch sind hier auch andere konstruktive Lösungen möglich.The spring 31 preferably biases the discharge channel 6 with the nozzle 15 or possibly only the nozzle 15 against the adjusting element 16. For this purpose, the spring 31 preferably engages on the side facing away from the nozzle 15 on the connecting piece 7. At the other end, the spring 31, for example, on a stationary part of the spray head 5, such as the lower part 14, or for example on the control element 16 or other cap or other actuator supported by the spray head 5. However, other constructive solutions are possible here.

Die Feder 31 ist vorzugsweise aus Kunststoff hergestellt.The spring 31 is preferably made of plastic.

Die Feder 31 ist vorzugsweise als Schraubenfeder ausgebildet. Jedoch kann es sich auch um eine Blattfeder oder sonstige Feder handeln.The spring 31 is preferably designed as a helical spring. However, it may also be a leaf spring or other spring.

Generell ist anzumerken, daß das Betätigungselement 11 auch unabhängig von dem Stellelement 16, insbesondere als separates Teil, ausgebildet sein kann.In general, it should be noted that the actuating element 11 can also be formed independently of the adjusting element 16, in particular as a separate part.

Vorzugsweise sind die Auslaßöffnungen 13 bei den Darstellungsbeispielen im Durchmesser kleiner als die Düsenöffnung 19. Jedoch ist es grundsätzlich auch möglich, daß nur eine Auslaßöffnung 13 im Querschnitt kleiner als die Düsenöffnung 19 ist. Wenn beispielsweise nur zwei Auslaßöffnungen 13 vorgesehen sind, kann dann die andere Auslaßöffnung 13 bedarfsweise auch den gleichen Durchmesser wie die Düsenöffnung 15 oder sogar einen größeren Durchmesser aufweisen.Preferably, the outlet openings 13 in the illustration examples in diameter are smaller than the nozzle opening 19. However, it is also possible in principle that only one outlet opening 13 in cross section is smaller than the nozzle opening 19. For example, if only two outlet openings 13 are provided, then the other outlet opening 13 may also have the same diameter as the nozzle opening 15 or even a larger diameter as required.

Generell ist es auch möglich, daß eine, mehrere oder alle Auslaßöffnungen 13 den gleichen Durchmesser wie die Düsenöffnung 19 aufweisen. Die gewünschte Beeinflussung der Sprühcharakteristik erfolgt dann insbesondere durch die Länge der jeweiligen Auslaßöffnung 19, insbesondere durch unterschiedliche radiale Dicken des Stellelements 16 im Bereich der jeweiligen Auslaßöffnung 19. Zur Variation der Länge der jeweiligen Auslaßöffnung 13 (genauer gesagt handelt es sich hier dann um Auslaßkanäle, auch wenn generell in der vorliegenden Beschreibung immer nur von Auslaßöffnungen gesprochen wird; der Begriff "Auslaßöffnung" ist daher in diesem allgemeinerem Sinne zu verstehen) kann bedarfsweise das Stellelement 16 auch nur im Bereich der jeweiligen Auslaßöffnung 13 entsprechend verdickt sein. Jedoch sind hier auch andere konstruktive Lösungen möglich.In general, it is also possible that one, several or all outlet openings 13 have the same diameter as the nozzle opening 19. The desired influencing of the spray characteristic is then effected in particular by the length of the respective outlet opening 19, in particular by different radial thicknesses of the adjusting element 16 in the region of the respective outlet opening 19. To vary the length of the respective outlet opening 13 (more precisely, these are then outlet channels, Although the term "outlet opening" is to be understood in this more general sense in the present description, the adjusting element 16 may also be thickened accordingly only in the area of the respective outlet opening 13. However, other constructive solutions are possible here.

Vorzugsweise ist der Sprühkopf 5 so ausgebildet, daß mittels des Stellelements 16 mindestes zwei unterschiedliche Sprühcharakteristika, insbesondere zwei unterschiedliche Sprühwinkel 21, einstellbar sind. Entsprechend weist das Stellelement 16 bzw. der Sprühkopf 5 vorzugsweise mindestens zwei oder nur zwei unterschiedliche Auslaßöffnungen 13 auf, die wahlweise zur Ausgabe der Flüssigkeit einsetzbar bzw. vor die Düse 15 bringbar.Preferably, the spray head 5 is formed so that by means of the adjusting element 16 at least two different spray characteristics, in particular two different spray angles 21, are adjustable. Accordingly, points the control element 16 or the spray head 5 preferably at least two or only two different outlet openings 13, which can be used either to dispense the liquid or in front of the nozzle 15 can be brought.

Die Sprührichtung des Sprühkopfs 5 verläuft vorzugsweise zumindest im wesentlichen horizontal und/oder quer zur Betätigungsrichtung bzw. Niederdrückrichtung.The spraying direction of the spray head 5 preferably runs at least substantially horizontally and / or transversely to the actuating direction or depression direction.

Die Sprührichtung des Sprühkopfs 5 verläuft zumindest im wesentlichen radial zur ringförmigen Erstreckung des Stellelements 16 und/oder zumindest im wesentlichen in der Ringebene des Stellelements 16.The spray direction of the spray head 5 runs at least substantially radially to the annular extent of the actuating element 16 and / or at least substantially in the ring plane of the actuating element 16.

Bei den beschriebenen Ausführungsformen weist das Stellelement 16 verschiedene Auslaßöffnungen 13 auf, die entsprechend zu unterschiedlichen Sprühcharakteristika führen. Grundsätzlich ist es jedoch auch möglich, eine verstellbare Auslaßöffnung 13 vor der Düsenöffnung 19 - also wie bei den anderen Ausführungsbeispielen auch wiederum abgabeseitig - anzuordnen. Beispielsweise kann dann durch blendenartige Veränderung des Durchmessers der Auslaßöffnung 13 eine entsprechende Veränderung der Sprühcharakteristik erreicht werden.In the described embodiments, the actuator 16 has different outlet openings 13, which lead to different spray characteristics accordingly. In principle, however, it is also possible to arrange an adjustable outlet opening 13 in front of the nozzle opening 19, ie, in the same way as in the other exemplary embodiments, on the discharge side. For example, can then be achieved by aperture-like change in the diameter of the outlet opening 13, a corresponding change in the spray characteristic.

Generell ist der Sprühkopf 5 vorzugsweise aus Kunststoff und/oder als Spritzgußteil hergestellt. Insbesondere sind vorzugsweise das Unterteil 14, der Ausgabekanal 6 und das Anschlußstück 7 einstückig ausgebildet. Das Stellelement 16 ist vorzugsweise ebenfalls einstückig ausgebildet und/oder auf den Sprühkopf 5 bzw. dessen Unterteil 14 aufgesteckt oder aufgerastet. Jedoch sind hier auch andere konstruktive Lösungen möglich.In general, the spray head 5 is preferably made of plastic and / or as an injection molded part. In particular, preferably, the lower part 14, the output channel 6 and the connecting piece 7 are integrally formed. The actuator 16 is preferably also integrally formed and / or plugged or snapped onto the spray head 5 and its lower part 14. However, other constructive solutions are possible here.
