Abstract

A sprinkler (1) has flow control means (10) for generating different flow behaviour patterns during the advance and return movement of its sprinkler head (2) so that on advance movement a far-reaching sharp jet, and on return movement a spraying jet which sprinkles the vicinity are discharged through one and the same nozzle outlet (11). <IMAGE>

Description

Die Erfindung betrifft einen Regner nach dem Oberbegriff des Patentanspruches 1. Mit solchen und ähnlichen Baueinheiten zum Fluidaustrag soll das Fluid, meist Wasser, über eine verhältnismäßig weite Distanz von z.B. mehreren Metern vom Regnerkopf bzw. Regnerausgang entfernt so ausgebracht werden, daß es ein vorbestimmtes Beregnungsfeld bestreicht, das meist etwa horizontal liegt bzw. durch eine horizontale Lage eine Meßbasis bildet. Hierzu wird das Wasser von dem ans Freie angrenzenden Regnerausgang über eine freie Strahlbahn, meist eine parabelähnliche Wurfbahn, unter Druck abgegeben und ab dem Ausgang findet keine weitere Berührung mit bzw. unmittelbare Führung des Fluidstrahles durch den Regner mehr statt.The invention relates to a sprinkler according to the preamble of Claim 1. With such and similar units the fluid, usually water, is to be discharged via a relatively long distance from e.g. several meters from Sprinkler head or sprinkler outlet are removed so that it covers a predetermined irrigation field, most of the time is approximately horizontal or a horizontal position Forms the basis of measurement. For this, the water from the outside adjacent sprinkler exit via a free jet path, mostly a parabola-like throwing track, released under pressure and off there is no further contact with or immediate exit The fluid jet is guided through the sprinkler more.

Zur Vegetations-Bewässerung können Regner mit während des Betriebes ortsfest stehendem Ausgang oder solche verwendet werden, bei welchen dem Fluidstrahl eine zu seiner Längsrichtung quer gerichtete Querbewegung z.B. dadurch vermittelt wird, daß der Regnerkopf eine zum Beregnungsfeld etwa parallele und/oder quer dazu liegende Bewegung, wie eine ständig gleichgerichtete und/oder eine hin- und hergehende Drehbewegung bzw. eine Axialbewegung ausführt. Um den Fluidstrahl möglichst weit austragen zu können, ist gegenüber annähernd horizontalen bzw. etwa vertikal nach oben oder nach unten gerichteten Ausrichtungen des Ausganges eine unter etwa 30 bis 45° schräg nach oben gerichtete Ausrichtung zu bevorzugen, wobei z. B. durch stabförmige bzw. nach oben ausfahrbare Ausbildung des Regnerkopfes eine verhältnismäßig hohe Lage des Ausganges gegenüber bzw. über dem Beregnungsfeld erzielt werden kann. Ein solcher Regner ist z. B. in der EP-Patentanmeldung 410 198 oder in der EP-Patentanmeldung 362 559 beschrieben, auf die zur Einbeziehung der dort erläuterten Merkmale und Wirkungen in die vorliegende Erfindung Bezug genommen wird.For irrigation of the vegetation, sprinklers can be used during the Operation stationary output or such used in which the fluid jet is one to its longitudinal direction transverse transverse movement e.g. thereby conveyed is that the sprinkler head is approximately parallel to the irrigation field and / or transverse movement, like a constant one rectified and / or a reciprocating rotary movement or executes an axial movement. To the fluid jet To be able to discharge as far as possible is approximate horizontally or approximately vertically upwards or downwards directional orientations of the exit one below about 30 preferred up to 45 ° inclined upward orientation, where z. B. by rod-shaped or extendable upwards Training the sprinkler head a relatively high location of the exit opposite or above the irrigation field can be. Such a sprinkler is e.g. B. in the EP patent application 410 198 or in EP patent application 362 559 described on the inclusion of those explained there Features and effects related to the present invention is taken.

Ist beabsichtigt, den Fluidstrahl bei einem durch den Druck im Wasserleitungsnetz bzw. durch eine Drossel gegebenen Zuführdruck möglichst weit über z. B. mehr als 3, 5 oder 10 Meter auszutragen, so wird die Form des Düsenausganges und der zu diesem führenden Fluidwege bzw. Kanalabschnitte der Fluidführung zweckmäßig so gewählt, daß eine linear beruhigte Strömung dem Düsenausgang zugeführt wird, und der Fluidstrahl den Düsenausgang als sogenannter Stechstrahl verläßt, welcher den Fluidausgang ohne wesentliche Zersprühung möglichst scharf gebündelt verläßt und auch über mehrere Meter gebündelt bleiben kann. Dieser Stechstrahl fächert dann erst in größerer Entfernung vom Fluidausgang auf und bewässert ein Beregnungsfeld vorbestimmter Flächengröße mit einer mittleren Bewässerungsdichte je Flächeneinheit, die zweckmäßig über das Beregnungsfeld im wesentlichen konstant ist.Is intended to apply the fluid jet at a pressure given in the water supply network or by a throttle Feed pressure as far as possible over z. B. more than 3, 5 or 10 Discharge meter, so the shape of the nozzle outlet and the leading to this fluid paths or channel sections The fluid flow is appropriately chosen so that it is linearly calm Flow is fed to the nozzle outlet, and the fluid jet leaves the nozzle outlet as a so-called pricking jet, which the fluid outlet as possible without substantial spraying leaves sharply bundled and also bundled over several meters can stay. This stinging beam then fanned in greater distance from the fluid outlet and irrigated Irrigation field of predetermined area size with an average Irrigation density per unit area, which is appropriate over the Irrigation field is essentially constant.

Zwischen dem im Abstand vom Regner liegenden Beregnungsfeld und dem Regner findet dagegen meist keine oder keine wesentliche Beregnung statt, so daß in diesem Feld allenfalls eine Beregnung mit gegenüber dem eigentlichen Beregnungsfeld wesentlich geringerer Beregnungsdichte gegeben ist. Man kann dem zwar durch entsprechende, z.B. asymmetrische Gestaltung des Regnerausganges entgegenwirken, jedoch ergibt sich dann eine reduzierte maximale Reichweite des Fluid- bzw. Stechstrahles, weil ein Teil des Fluidstrahles als Sprühstrahl für den Nahbereich abgezweigt wird.Between the irrigation field at a distance from the sprinkler and the sprinkler, on the other hand, usually does not find any or no essential Irrigation instead, so that in this field at most a Sprinkling with compared to the actual irrigation field there is a significantly lower irrigation density. One can by appropriate, e.g. asymmetrical design counteract the sprinkler outlet, but then results a reduced maximum range of the fluid or penetration jet, because part of the fluid jet acts as a spray jet for the close range is branched off.

Ähnliches gilt auch dann, wenn der Ausgang bzw. die Stelle letzter Berührung des Fluidstrahles mit dem Regner durch ein Strahl-Störglied gebildet ist, das rhythmisch in den Stechstrahl bewegt wird und dadurch jedes Mal eien Zersprühung für den Nahbereich bewirkt. Die kurzen Sprühimpulse reichen meist nicht aus, den Nahbereich bzw. das Feld zwischen dem Beregnungsfeld des Stechstrahles und dem Regner mit etwa gleicher Bewässerungsdichte wie das Stechstrahl-Beregnungsfeld zu bewässern. Auch wenn der Stechstrahl bzw. der Regnerausgang durch eine ruckartige Querbewegung von einer Ruhestellung in eine nächste bewegt wird, wird zwar während dieser Impulsbewegung die Reichweite des Fluidstrahles geringfügig reduziert, jedoch nicht so, daß dadurch der Nahbereich in der genannten Weise bewässert wird.The same applies if the exit or the place last touch of the fluid jet with the sprinkler Beam perturbator is formed that is rhythmic in the stab is moved and thereby a spray for each time causes the close range. The short spray pulses are usually sufficient not out, the close range or the field between the irrigation field the jet and the sprinkler with about the same Irrigation density like the sting irrigation field too water. Even if the lancing jet or the sprinkler outlet by a jerky transverse movement from a rest position in a next one is moved during this impulse movement the range of the fluid jet is slightly reduced, but not in such a way that the close range in the is irrigated.

Durch die US-A-4 281 793 ist ein Regner bekannt geworden, der zwar Antriebsmittel zur Richtungsumkehr der Querbewegung des Fluidstrahles sowie eine Steuereinrichtung zur Änderung der Strahlweite aufweist, jedoch arbeitet diese Steuereinrichtung völlig unabhängig von der Richtungsumkehr, nämlich in Abhängigkeit von der Winkelstellung des Regnerkopfes gegenüber einer Steuereinheit. Dabei wird mit der Steuereinrichtung der Durchlaßquerschnitt einer Steuerscheibe verändert, wodurch sich unterschiedliche Drosselquerschnitte und daher auch unterschiedliche Durchsatzmengen des Wassers ergeben.A sprinkler has become known from US-A-4,281,793 although drive means for reversing the direction of the transverse movement of the Fluid jets and a control device for changing the Has beam width, but this control device works completely independent of the reversal of direction, namely depending from the angular position of the sprinkler head a control unit. The control device is used for Passage cross section of a control disc changed, whereby different throttle cross sections and therefore also result in different throughputs of the water.

Der Erfindung liegt auch die Aufgabe zugrunde, einen Regner zu schaffen, bei welchem Nachteile bekannter Ausbildungen bzw. der beschriebenen Art vermieden sind und der insbesondere bei großer Reichweite ein z.B. in Richtung seiner Strahlachse zum Regner hin vergrößertes Beregnungsfeld mit über dessen Ausdehnung etwa gleichmäßiger Beregnungsdichte so gewährleistet, daß in Ansicht von oben auch eine Beregnung bis wenige Meter bzw. weniger als einen Meter vom Regler entfernt oder unmittelbar bis an den Regnerausgang möglcih ist. Ferner soll der Regner möglichst sicher im Betrieb bzw. weniger anfällig gegen Störungen sein oder im Bereich des Regnerausganges keine während des Betriebes Bewegungen ausführenden Teile oder Steuerungsglieder aufweisen.The invention is also based on the object of a sprinkler to create the disadvantages of known training or of the type described are avoided and in particular with a long range, e.g. in the direction of its beam axis irrigation field enlarged towards the sprinkler with over the extent of which is approximately uniform ensures that in the top view also a sprinkler up to a few meters or less than one meter from the controller removed or possible right up to the sprinkler exit is. Furthermore, the sprinkler should be as safe as possible in operation or less susceptible to interference or in the area of Sprinkler output no movements during operation have executing parts or control elements.

Erfindungsgemäß sind die Merkmale nach Patentanspruch 1 vorgesehen. Sie umfassen Mittel, um das Fluid innerhalb es Regnerkopfes bzw. in Strömungsrichtung vor dem Ausgang hinsichtlich einer Strömung so zu beeinflussen bzw. umzuleiten, daß es den Regner in stark unterschiedlichen Strahlformen bzw. mit stark unterschiedlichen Reichweiten verläßt. Die unterschiedlichen Strahlformen werden dabei vom Regner zweckmäßig wenigstens teilweise zeitlich aufeinanderfolgend abgegeben, z.B. unmittelbar und im wesentlichen ohne Austragunterbrechung aneinander anschließend oder mit geringer Überlappung derart, daß der Austrag der nachfolgenden Strahlform kurze Zeit vor Beendigung des Austrages der vorangehenden Strahlform beginnt. Es ist denkbar, mehr als zwei unterschiedliche Strahlformen vorzusehen, und zweckmäßig grenzen die beiden Beregnungsfelder jeweils zweier unterschiedlicher Strahlformen im wesentlichen aneinander an bzw. überlappen sie einander geringfügig, so daß eine lückenlose Bewässerung gegeben ist.According to the invention, the features according to claim 1 intended. They include means to keep the fluid inside it Sprinkler head or in the flow direction in front of the exit to influence or redirect with regard to a flow, that it is the sprinkler in very different jet shapes or leaves with very different ranges. The different jet shapes are from the sprinkler expediently at least partially in succession delivered, e.g. immediately and essentially without interrupting the discharge adjoining each other or with less Overlap such that the discharge of the subsequent jet shape shortly before the termination of the previous one Beam shape begins. It is conceivable to have more than two different ones Provide jet shapes and limit them appropriately the two irrigation fields each have two different ones Beam shapes essentially overlap or overlap they each other slightly, so that complete irrigation given is.

Es ist denkbar, mindestens zwei unterschiedliche Strahlformen durch abwechselnden Austrag aus gesonderten Düsen bzw. Düsenöffnungen zu bewirken, welche entsprechend unterschiedlich, z.B. als Stechstrahldüse und als Sprühdüse ausgebildet sind. Ferner können unterschiedliche Strahlformen durch Querbewegungen mit stark unterschiedlichen Geschwindigkeiten bewirkt werden, wobei jedoch im Falle einer zum Beregnungsfeld etwa parallel gerichteten Querbewegung annähernd derselbe Beregnungssektor einmal mit größerer Geschwindigkeit und einmal mit geringerer Geschwindigkeit beaufschlagt wird, so daß bei größerer Geschwindigkeit der Nahbereich und bei geringerer Geschwindigkeit der weiter entfernte Bereich desselben Sektors bewässert wird. It is conceivable to have at least two different jet shapes through alternate discharge from separate nozzles or To cause nozzle openings, which differ accordingly, e.g. designed as a jet nozzle and as a spray nozzle are. Furthermore, different beam shapes can be used Cross movements with very different speeds can be effected, but in the case of one to the irrigation field approximately parallel transverse movement approximately the same Irrigation sector once with greater speed and is once applied at a lower speed, so that at higher speeds the close range and at lower speed the more distant area irrigated in the same sector.

Besonders zweckmäßig ist es, wenn mindestens zwei unterschiedliche Strahlformen abwechselnd aufeinander folgend und ohne jegliche Austragunterbrechung bzw. Austragreduzierung durch ein und denselben Ausgang ausgetragen werden, der zweckmäßig so ausgebildet ist, daß aus ihm ein Stechstrahl ausgetragen werden kann. Wird in Strömungsrichtung vor dem Ausgang die Strömung entsprechend beeinflußt, z. B. gegenüber dem Austrag als Stechstrahl weniger beruhigt oder stärker verwirbelt, so führt diese Strömungsbeeinflussung dazu, daß dann das Wasser den Ausgang in einer gegenüber dem Stechstrahl wesentlich stärker versprühten Form verläßt, wodurch seine Reichweite entsprechend reduziert wird und es den Nahbereich beaufschlagt.It is particularly useful if at least two different ones Alternating successive and without any interruption or reduction in discharge through one and the same exit, the is expediently designed so that a puncture jet from it can be carried out. Is in the flow direction before Output affects the flow accordingly, e.g. B. opposite the discharge as a pricking jet is less calmed or stronger swirled, this flow influence leads to the fact that then the water's exit in a direction opposite the stab leaves much more sprayed form, whereby its range is reduced accordingly and it does Close range.

Gegenüber einer willkürlichen Umschaltung zwischen den Strahlformen ist eine selbsttätige Umschaltung zu bevorzugen, wobei dann statt eines manuell zu betätigenden Umschalt-Antriebes zweckmäßig ein solcher vorgesehen ist, welcher während des Betriebes des Regners mitläuft und nach vorbestimmten Zeit- bzw. Wegintervallen die Umschaltung vornimmt. Die Antriebsenergie wird dabei zweckmäßig dem den Regner durchströmenden Fluid entnommen, wobei der Antrieb selbst die Strömung in der beschriebenen Weise abwechselnd unterschiedlich beeinflussen kann. Je nach den Erfordernissen kann dabei das je Zeiteinheit abgegebene Fluid-Austragvolumen während des Betriebes mit gesonderten Strahlformen etwa gleich oder unterschiedlich sein, z. B. so, daß das geringere Austragvolumen mindestens die Hälfte oder drei Viertel des größeren Austragvolumens beträgt und für die größere bzw. kleinere Reichweite vorgesehen ist.Compared to an arbitrary switch between the Automatic switching is preferable, then instead of a manually operated changeover drive expediently one is provided which runs during the operation of the sprinkler and according to predetermined Time or path intervals make the switchover. The drive energy is expedient to that of the sprinkler flowing fluid removed, the drive itself the Flow alternately in the manner described can influence. Depending on the requirements, this can be done the fluid discharge volume delivered per unit of time during operation with separate jet shapes approximately the same or be different, e.g. B. so that the lower discharge volume at least half or three quarters of the larger Discharge volume is and for the larger or smaller Range is provided.

Die Beeinflussung der Strömung kann durch zahlreiche unterschiedliche Maßnahmen bewirkt werden, welche jeweils einzeln oder in Kombination vorgesehen sein können. Z. B. kann ein während des Betriebes selbsttätig in unterschiedliche Funktionsstellungen überführbares und/oder manuell einstell- bzw. justierbares Strömungsstörglied vorgesehen sein, das in einer Stellung eine verhältnismäßig lineare sowie beruhigte Strömung bis zum Ausgang zuläßt und in mindestens einer weiteren Stellung diese Strömung mit Wirkung bis zum Ausgang verwirbelt. Ferner können gesonderte Fluidwege vorgesehen sein, welche die Strömung in der beschriebenen Weise unterschiedlich beeinflussen und abwechselnd stärker bzw. schwächer durchströmt oder durch Schließung wenigstens teilweise gesperrt bzw. geöffnet werden. Gesonderte Strömungswege können dabei durch gesonderte Kanalabschnitte oder einen gemeinsamen Kanalabschnitt bzw. eine Kammer gebildet sein, in welcher die Strömung abwechsend in unterschiedlichen Richtungen bzw. über unterschiedlich lange Wege geführt wird, z. B. durch Leitflächen.The flow can be influenced by numerous different ones Measures are effected, each one individually or can be provided in combination. For example, a automatically in different functional positions during operation transferable and / or manually adjustable or adjustable flow disturbance member can be provided in a Position a relatively linear and calm flow to the exit and in at least one other Position this flow with effect swirled to the exit. Furthermore, separate fluid paths can be provided which the flow differs in the manner described influence and alternately stronger or weaker flows through or at least partially through closure locked or opened. Separate flow paths can by separate channel sections or a common channel section or a chamber can be formed in which alternately flows in different directions or is led over different distances, e.g. B. through guiding surfaces.

Des weiteren kann in einem Kanalabschnitt das Wasser für eine Strahlform in einer um die Kanalachse rotierenden Strömungswalze geführt werden, während es für die andere Strahlform weniger stark oder im wesentlichen nicht rotiert und mit entsprechendem Strömungsverhalten den Ausgang erreicht. Auch kann ein an eine Kammer anschließender und demgegenüber zweckmäßig vielfach engerer sowie nicht achssymmetrischer Einlaß eines Kanalabschnittes abwechselnd in unterschiedlichen Richtungen angeströmt werden, wobei sich für jede Anströmrichtung ein anderes Strömungsverhalten des Wassers in diesem Kanalabschnitt ergibt und das Wasser dann mit diesem Strömungsverhalten im wesentlichen bis zum Ausgang geführt wird. Ferner können Leitflächen durch die Wasserkraft beweglich sein bzw. weite Kammern bilden, in welchen das Wasser z. B. in einer Drehbewegung über einen Drehweg von mehr als 90, 180 oder annähernd 270 Winkelgraden mitgenommen wird. Furthermore, the water for a Jet shape in a flow roller rotating around the channel axis be guided while it is for the other beam shape less strong or essentially not rotating and with Appropriate flow behavior reached the exit. Also can be a chamber adjoining and opposite expediently many times narrower and not axially symmetrical Intake of a channel section alternately in different Directions are poured towards each other Flow direction a different flow behavior of the water in this section of the canal and the water with it Flow behavior essentially led to the exit becomes. Furthermore, guide surfaces can be moved by hydropower be or form wide chambers in which the water e.g. B. in a rotary motion over a rotational path of more than 90, 180 or approximately 270 degrees.

Weiterhin kann in der Fluidführung eine in der beschriebenen Weise zwischen unterschiedlichen Drosselwirkungen umschaltbare Drossel vorgesehen sein, durch die das Durchflußvolumen bzw. der Fluiddruck am Ausgang verändert wird. Der Regner bildet eine in sich geschlossene Baueinheit, die mit einem zweckmäßig feststehend an ihrem Grundkörper vorgesehenen Einlaß an eine Fluidquelle, insbesondere eine Druckquelle, anzuschließen ist, wobei die genannten Steuermittel zweckmäßig in Strömungsrichtung nach diesem Einlaß oder höchstens im Bereich dieses Einlasses vorgesehen sind.Furthermore, one of the described in the fluid guide Switchable between different throttle effects Throttle can be provided through which the flow volume or the fluid pressure at the outlet is changed. The sprinkler forms a self-contained unit, which with a Appropriately fixed provided on their base body Inlet to a fluid source, in particular a pressure source, is to be connected, the said control means expedient in the direction of flow after this inlet or at most in Area of this inlet are provided.

Besonders zweckmäßig ist es, wenn der Strömungsweg des Fluids zwischen den die Strömung beeinflussenden Steuermitteln bzw. Steuergliedern und dem Ausgang möglichst klein bzw. kleiner als der entsprechende Abstand vom Einlaß ist. Z. B. können Steuermittel im Bereich des Einlasses eines über den größten Teil seiner Längserstreckung annähernd geradlinig bis zum Ausgang bzw. dem Eingang einer Düse oder eines Düseneinsatzes geführten Endkanales vorgesehen sein, gegenüber welchem dieser Düseneingang oder Düsenausgang zweckmäßig wesentlich verengt ist. Der Einlaß des Endkanales kann an eine gegenüber ihm mehrfach erweiterte bzw. größervolumige Kammer anschließen, in welcher die Strömung beruhigt, verwirbelt, in unterschiedlichen Richtungen und/oder über unterschiedlich lange Wege geführt werden kann. Der Einlaß des Endkanales bzw. des wegführenden Kanalabschnittes kann dabei wie mindestens ein die Strömung unmittelbar beeinflussendes Steuerglied etwa in der Ebene einer Begrenzungswand der Kammer liegen, wobei gegenüber einer Lage in einer Mantelwand eine Lage in einer Stirnwand zu bevorzugen ist. Auch ist es vorteilhaft, wenn der Durchlaßquerschnitt dieses Einlasses gegenüber demjenigen des übrigen Endkanales nach Art einer Drosselstelle reduziert ist, und wenn der Endkanal bis zum Düseneingang annähernd konstante Durchlaßquerschnitte aufweist sowie nicht ringförmig, sondern frei von einem Kanalkern über seinen gesamten Querschnitt bis zu seiner Mittelachse offen ist. Der Durchflußquerschnitt des Einlasses des Endkanales ist jedoch zweckmäßig wesentlich größer als derjenige des Regnerausganges.It is particularly expedient if the flow path of the fluid between the control means influencing the flow or Control elements and the output as small or smaller as possible than the corresponding distance from the inlet. For example, you can Control means in the area of the intake one over the largest Part of its longitudinal extent almost straight to Exit or the entrance of a nozzle or a nozzle insert guided end channel can be provided, opposite which this nozzle inlet or nozzle outlet is expediently essential is narrowed. The inlet of the end channel can face one connect it with a chamber that has been expanded or enlarged several times, in which the current calms, swirls, in different Directions and / or over different lengths Ways can be led. The inlet of the end channel or leading channel section can be like at least one control element directly influencing the flow approximately in the plane of a boundary wall of the chamber, where compared to a position in a jacket wall, a position in a Front wall is preferable. It is also advantageous if the passage cross section of this inlet compared to that the remaining end channel reduced in the manner of a throttle point and when the end channel is almost up to the nozzle inlet has constant passage cross-sections and not annular, but free of a channel core over its entire Cross section is open up to its central axis. The flow cross section of the inlet of the end channel, however expediently much larger than that of the sprinkler outlet.

Der als Sektoren-Regner ausgebildete Regner 1 weist einen in Fig. 1 dargestellten Regnerkopf 2 auf, der bzw. dessen Regnerdüse Drehbereiche im gesteuerten Vor- und Rücklauf durchläuft, wobei die Drehbereiche stufenlos zwischen etwa 20° und 360° einstellbar sind. Für die kontinuierlich reversierende Drehbewegung ist im Grundkörper 4 des Regnerkopfes 2 ein Fluid-Antrieb 3 vorgesehen, welcher in einem vom Düsenkopf 5 gesonderten Antriebsgehäuse 6 angeordnet ist, wobei der Düsenkopf 5 und das Antriebsgehäuse 6 den Grundkörper 4 des Regnerkopfes 2 bilden. Das Antriebsgehäuse 6 besteht aus zwei axial zusammengesetzten Gehäuseteilen 7, 8, und auf einen Gehäuseteil 8 ist der gehäuseförmige Düsenkopf 5 mit einem Kappen- bzw. Mantelabschnitt axial so aufgesetzt, daß sein Außenumfang eine annähernd kontinuierliche Fortsetzung der Außenumfänge der Gehäuseteile 7, 8 bildet. Zur Umkehr der Antriebsrichtung des Antriebes 3 ist eine Reversier-Steuerung 9 vorgesehen, welche wegabhängig bzw. am Ende jeweils eines Drehweges die Drehrichtung durch mechanischen Anschlag umschaltet. Der Grundkörper 4 bzw. die Gehäuse 5, 6 führen dabei gemeinsam mit dem Antrieb 3 die Drehbewegung gegenüber einem Schaft aus, welcher an das untere Ende des Gehäuseteiles 7 mit etwa dessen Außenweite anschließt und der einen Laufkranz für den Eingriff eines Abtriebsläufers des Antriebes 3 hat.The sprinkler 1 designed as a sector sprinkler has an in Fig. 1 shown sprinkler head 2, the or Sprinkler nozzle Rotation ranges in the controlled flow and return passes through, the rotation ranges continuously between about 20 ° and 360 ° are adjustable. For the continuously reversing Rotary movement is in the base body 4 of the sprinkler head 2 a fluid drive 3 is provided, which in one of the nozzle head 5 separate drive housing 6 is arranged, wherein the nozzle head 5 and the drive housing 6 the base body 4 form the sprinkler head 2. The drive housing 6 consists of two axially assembled housing parts 7, 8, and a housing part 8 is the housing-shaped nozzle head 5 with axially placed a cap or jacket section so that its outer circumference is an almost continuous continuation the outer peripheries of the housing parts 7, 8 forms. To reverse the Drive direction of the drive 3 is a reversing control 9 provided, which depending on the path or at the end one Direction of rotation by mechanical stop toggles. The base body 4 and the housing 5, 6 guide together with the drive 3 opposite the rotary movement a shaft, which at the lower end of the housing part 7 with approximately its outer width and one Ring for the engagement of an output rotor of the drive 3 has.

Zur Änderung der Strahlform des aus dem Regner 1 austretenden Bewässerungsstrahles ist eine Steuereinrichtung 10 mit einer Vielzahl von Steuergliedern 11, 13 bis 20, 23 bis 30 und 32 bis 36 vorgesehen, welche entweder feststehende oder während des Betriebes sich bewegende Steuerglieder bilden. Der gegenüber den etwa vertikal auszurichtenden bzw. parallelen Mittelachsen des Grundkörpers 4 und des Antriebes 3 unter einem Winkel von etwa 60° schräg nach oben gerichtete Ausgang 11 liegt im obersten Bereich des Regnerkopfes 2 bzw. des Düsenkopfes 5 nahe bei der etwa zylindrischen Hüllfläche des Grundkörpers 4. Der Wasser-Eingang 12 liegt am unteren Ende des Grundkörpers 4 oder kann durch einen Anschlußstutzen an einem Sockel gebildet sein, welcher den Regnerkopf 2 drehbar aufnimmt und ggfs. durch den Schaft gebildet ist, in welchen der Regnerkopf 2 mit seiner Oberseite annähernd bündig abschließend in eine Nicht-betriebslage zu versenken bzw. durch Wasserdruck wieder nach oben quer zur Achse des Ausganges 11 ausfahrbar ist.To change the jet shape of the exiting from the sprinkler 1 Irrigation jet is a control device 10 with a plurality of control elements 11, 13 to 20, 23 to 30 and 32 to 36 are provided, which are either fixed or form moving control elements during operation. The one compared to the one that is approximately vertical or parallel Central axes of the base body 4 and the drive 3 directed obliquely upwards at an angle of approximately 60 ° Output 11 is in the uppermost area of sprinkler head 2 or of the nozzle head 5 close to the approximately cylindrical envelope surface of the base body 4. The water inlet 12 is at the bottom End of the base body 4 or can be through a connection piece be formed on a base which holds the sprinkler head 2 rotatably receives and possibly formed by the shaft, in which the top of the sprinkler head 2 approximately finally flush into a non-operational position or by water pressure back up to the axis of the Exit 11 is extendable.

Zwischen dem Eingang 12 und dem Ausgang 11 bilden die Gehäuseteile des Grundkörpers 4 eine durch zahlreiche Abschnitte bzw. Kanalabschnitte oder Kammern gebildete Fluidführung 13, über welche auch der Antrieb 3 betrieben wird. An den in einer unteren Stirnwand des Gehäuseteiles 7 vorgesehenen und z. B. durch eine den Regnerkopf 2 drehbar aufnehmende Hohlachse des Sockels gebildeten Eingang 12 schließt eine seitlich gegenüber der Mittelachse des Regnerkopfes 2 versetzte Steuerkammer 14 an, welche durch die beiden Gehäuseteile 7, 8 begrenzt ist und die Reversier-Steuerung 9 aufnimmt. Eine obere, durch den Gehäuseteil 8 gebildete Stirnwand der Steuerkammer 14 ist von zwei aufrechten Kanalabschnitten 15, 16 durchsetzt, welche jeweils beiderseits dieser Stirnwand nach Art von Rohrstutzen vorstehen, so daß ihre unteren Enden an die Steuerkammer 14 angeschlossen sind.The housing parts form between the input 12 and the output 11 of the base body 4 one through numerous sections or channel sections or chambers formed fluid guide 13, via which the drive 3 is also operated. To the in provided a lower end wall of the housing part 7 and e.g. B. by a rotatable receiving the sprinkler head 2 hollow axis of the base formed entrance 12 closes one laterally offset from the center axis of the sprinkler head 2 Control chamber 14, which through the two housing parts 7, 8th is limited and the reversing control 9 receives. A upper end wall formed by the housing part 8 Control chamber 14 is of two upright channel sections 15, 16 penetrates, which on both sides of this end wall protrude like a pipe socket so that its lower ends are connected to the control chamber 14.

Die oberen Enden der in geringem Abstand benachbart zueinander liegenden Kanalabschnitte 15, 16 münden in einer an die andere Seite der genannten Stirnwand des Gehäuseteiles 8 anschließenden Steuerkammer 17, welche bis auf Wandungsdicken annähernd gleiche Weite wie die Gehäuseteile 5, 8 hat und durch diese begrenzt ist. In diese Steuerkammer 17 münden die beiden Kanalabschnitte 15, 16 jeweils mit einer in ihrer Längsrichtung schlitzförmigen Fluiddüse 18, 19, wobei die Austragrichtung der Fluiddüsen 18, 19 unter einem spitzen Winkel von etwa 40° voneinander weg gegen den Innenumfang der Steuerkammer 17 gerichtet sind. Die zur Mittelachse der Steuerkammer 17 etwa parallelen Fluiddüsen 17, 18 liegen symmetrisch beiderseits einer Axialebene der Steuerkammer 17 sowie gegenüber der dazu rechtwinkligen Axialebene zum Innenumfang der Steuerkammer 17 zurückversetzt. Im Querschnitt gemäß Fig. 2 liegen die Mittelachsen der Fluiddüsen 18, 19 am Innenumfang der Steuerkammer 17 gegenüber dessen Mittelachse in einem Bogenabstand von 90° oder mehr auseinander.The upper ends of the spaced adjacent to each other lying channel sections 15, 16 open into one of the other side of said end wall of the housing part 8 adjoining control chamber 17, which is down to wall thicknesses approximately the same width as the housing parts 5, 8 and is limited by this. Open into this control chamber 17 the two channel sections 15, 16 each with one in their Longitudinal slot-shaped fluid nozzle 18, 19, the Direction of discharge of the fluid nozzles 18, 19 under a pointed Angles of about 40 ° apart from each other against the inner circumference of the Control chamber 17 are directed. The central axis of the Control chamber 17 are approximately parallel fluid nozzles 17, 18 symmetrically on both sides of an axial plane of the control chamber 17 as well as opposite to the axial plane perpendicular to it Inner circumference of the control chamber 17 set back. In cross section 2, the central axes of the fluid nozzles are located 18, 19 on the inner circumference of the control chamber 17 opposite to it Center axis apart at an arc distance of 90 ° or more.

In der Steuerkammer 17 ist ferner ein Steuerrotor 20 um eine zur Mittelachse 22 der Steuerkammer 17 bzw. des Grundkörpers 4 parallele, jedoch exzentrische Rotorachse 21 drehbar gelagert, dessen Außenumfang unmittelbar benachbart zu den Fluiddüsen 18, 19 liegt, so daß er diese annähernd abdeckt. Der verhältnismäßig breite Napfmantel des annähernd napfförmigen Steuerrotors 20 ist durch etwa radial ausgerichtete und mit Lückenabständen aufeinander folgende Leit- bzw. Schaufelstege gebildet, zwischen die das aus den Fluiddüsen 18, 19 austretenden Wasser unmittelbar eintreten kann. Am Innenumfang sind die Lücken durch einen Mantel geschlossen, der auch an seinem näher beim Gehäuseteil 7 liegenden Boden geschlossen ist. Die Rotorachse 21 einerseits und die Fluiddüsen 18, 19 andererseits sind mit Abstand beiderseits derjenigen Axialebene der Steuerkammer 17 vorgesehen, die zu der zwischen den Fluiddüsen 18, 19 liegenden gemeinsamen Axialebene der Steuerkammer 17 und des Steuerrotors 20 rechtwinklig ist. Der gegenüber dem Innenumfang der Steuerkammer 17 wesentlich kleinere Außenumfang des Steuerrotors 20 reicht an einer Stelle bis nahe an diesen Innenumfang. Von der Innenseite der oberen Stirnwand des Gehäuseteiles 5 stehen stegförmige Leitglieder bzw. Leitflächen 23 ab, welche seitlich an die voneinander abgekehrten Seiten der Fluiddüsen 18, 19 anschließend den Außenumfang des Steuerrotors 20 nur mit Spaltabstand über einen kleinen Bogenwinkel umgeben und in dieser Umfangsrichtung voneinander weggerichtet sind. Durch die Leitflächen wird das aus den Fluiddüsen 18, 19 austretende Wasser zwischen die Schaufelstege des Steuerrotors 20 gezwungen, wonach es frei in die Steuerkammer 17 und gegen deren Innenumfang austreten kann.In the control chamber 17 is also a control rotor 20 by one to the central axis 22 of the control chamber 17 or the base body 4 parallel, but eccentric rotor axis 21 rotatable stored, the outer periphery immediately adjacent to the Fluid nozzles 18, 19 is located so that it approximately covers them. The relatively broad bowl shell of the approximately bowl-shaped Control rotor 20 is approximately radially aligned and with gaps between successive guide or vane bars formed between which the fluid nozzles 18, 19th escaping water can enter immediately. On the inner circumference the gaps are closed by a coat that too closed at its bottom closer to the housing part 7 is. The rotor axis 21 on the one hand and the fluid nozzles 18, 19 on the other hand are by far both sides of those Axial plane of the control chamber 17 is provided, which to the between the common axial plane lying the fluid nozzles 18, 19 the control chamber 17 and the control rotor 20 is rectangular. The essential compared to the inner circumference of the control chamber 17 smaller outer circumference of the control rotor 20 extends to one Place close to this inner circumference. From the inside of the top end wall of the housing part 5 are web-shaped Guide members or guide surfaces 23, which laterally to the sides of the fluid nozzles 18, 19 facing away from one another the outer circumference of the control rotor 20 only with Gap distance surrounded by a small arc angle and in are directed away from each other in this circumferential direction. By the guide surfaces will be the one emerging from the fluid nozzles 18, 19 Water between the blade webs of the control rotor 20 forced, after which it is free in the control chamber 17 and against whose inner circumference can emerge.

In der genannten Stirnwand 24 des Gehäuseteiles 5 bzw. diese durchsetzend ist in Umfangsrichtung um die Achsen 21, 22 unmittelbar benachbart zur Fluiddüse 18 bzw. zur zugehörigen Leitfläche 23 ein Einlaß 25 vorgesehen, der quer zur Mittelachse 22 eine etwa um die Hälfte größere Erstreckung als in Umfangsrichtung um die Mittelachse 22 hat. Der gegenüber dem Außenumfang des Steuerrotors 20 im zugehörigen Bereich einen kleineren Abstand vom Innenumfang der Steuerkammer 17 aufweisende Einlaß 25 wird in Ansicht gemäß Fig. 2 nur auf seinem größeren, radial innen liegenden Teil seiner Längserstreckung vom Rotor 20 überdeckt, liegt mit seinem äußeren, breitesten Teil frei und ist durch eine konkav sowie radial nach innen progressiv gekrümmte Begrenzung in Richtung zur Mittelachse 22 verjüngt, von welcher er einen größeren Abstand als vom Innenumfang der Steuerkammer 17 hat. Der Einlaß 25 bildet das in Strömungsrichtung hintere Ende eines unmittelbar zum Ausgang 11 führenden Endkanales 26 des Düsenkopfes 5 und liegt in einer zur Mittelachse diese Endkanales 26 spitzwinkligen Ebene von etwa 30 bis 45°, so daß der Innenumfang des Endkanales 26 unmittelbar scharfwinklig an das zur Mittelachse 22 benachbart schmalere Ende des Einlasses 25 anschließt, während der Innenumfang des Endkanales 26 an das gegenüberliegende Ende des Einlasses 25 annähernd rechtwinklig zu dessen Ebene anschließt.In said end wall 24 of the housing part 5 or this is penetrating in the circumferential direction around the axes 21, 22 immediately adjacent to the fluid nozzle 18 or to the associated one Guide surface 23 an inlet 25 is provided which is transverse to the central axis 22 an extension that is about half as large as in Has circumferential direction about the central axis 22. The one opposite the Outer circumference of the control rotor 20 in the associated area having a smaller distance from the inner circumference of the control chamber 17 Inlet 25 is shown in FIG. 2 only on its larger, radially inner part of its longitudinal extent covered by the rotor 20, lies with its outer, widest Part free and is concave as well as radially inward progressively curved boundary towards the central axis 22 tapers, from which it is a greater distance than from Has inner circumference of the control chamber 17. The inlet 25 forms that in the direction of flow at the back of an immediate Exit 11 leading end channel 26 of the nozzle head 5 and lies in an acute angle to the central axis of this end channel 26 Plane of about 30 to 45 °, so that the inner circumference of the End channel 26 directly at a sharp angle to the central axis 22 adjoins narrower end of the inlet 25, while the inner circumference of the end channel 26 to the opposite End of the inlet 25 approximately at right angles whose level joins.

In Ansicht gemäß Fig. 2 ist der Endkanal 26 weiter bzw. breiter als der Einlaß 25, wobei er jedoch an der von der Fluiddüse 18 abgekehrten Seite des Einlasses 25 annähernd tangential anschließt, so daß er auf der näher bei der Fluiddüse 18 liegenden Seite in seiner Radialrichtung über den Einlaß 25 vorsteht. In diesem Bereich ist der Endkanal 26 von der Steuerkammer 17 durch einen dünnen Steuersteg 27 getrennt, welcher die zugehörige, annähernd geradlinige sowie von der Fluiddüse 18 weggerichtete Längsbegrenzung 27 des Einlasses 25 bildet und bis zu welcher annähernd die zugehörige Leitfläche 23 reicht. Die untere Außenfläche des Steuersteges 27 liegt etwa in der Ebene der Innenseite der Stirnwand 24, welche auch Verschlußglieder aufweist, mit welchen die oberen Enden der Kanalabschnitte 15, 16 so verschlossen sind, daß nur die von ihren Umfängen wegführenden Fluiddüsen 18, 19 offen sind. Die obere Stirnfläche des Steuerungsrotors 20 reicht mit geringem Spaltabstand nahezu bis an die Stirnwand 24. Der Kanal liegt etwa diametral zur Achse 22, so daß der Ausgang 11 und der Einlaß 25 auf voneinander abgekehrten Seiten der Achse 22 axial gegeneinander versetzt vorgesehen sind.2, the end channel 26 is wider or wider than the inlet 25, however, it is at that of the Fluid nozzle 18 side of the inlet 25 approximately connects tangentially so that it is closer to the Fluid nozzle 18 lying side in its radial direction protrudes the inlet 25. The end channel 26 is in this area from the control chamber 17 through a thin control web 27 separated, which is the associated, almost straight as well as longitudinal boundary 27 of the fluid nozzle directed away Inlet 25 forms and up to which approximately the associated Guide surface 23 is sufficient. The lower outer surface of the control bridge 27 lies approximately in the plane of the inside of the end wall 24, which also has closure members with which the upper ends of the channel sections 15, 16 closed in this way are that only the fluid nozzles leading away from their circumference 18, 19 are open. The top face of the control rotor 20 with a small gap distance almost reaches the front wall 24. The channel is approximately diametrical to axis 22, so that the outlet 11 and the inlet 25 are facing away from each other Sides of the axis 22 are provided axially offset from one another are.

Der Ausgang 11 ist durch eine Düse 28 bzw. einen leicht auswechselbar in den Düsenkopf 5 eingesetzten Düseneinsatz gebildet, welcher mit einer Hülse eng anliegend in den Endkanal 26 hineinragt und innerhalb von diesem den Düseneingang 29 bildet. Der Abstand zwischen dem Düseneingang 29 und dem im spitzen Winkel dazu liegenden Einlaß 25 bzw. Steuerglied 27 ist kleiner als das Dreifache oder Doppelte der Innenweite des Endkanales 26, gegenüber welchem die Innenweite des Einganges 29 nur geringfügig reduziert ist. Vom Düseneingang 29 erstreckt sich mit im wesentlichen gleicher Weite in Strömungsrichtung ein Eingangskanal bis zu einem wesentlich verengten, kürzeren sowie zylindrischen Düsenkanal 30, in welchen der Eingangskanal über einen kegelstumpfförmigen Abschnitt übergeht und dessen Länge höchstens so groß wie seine Breite oder demgegenüber kleiner ist.The outlet 11 is easy through a nozzle 28 or one replaceable in the nozzle head 5 inserted nozzle insert formed, which fits tightly with a sleeve in the end channel 26 protrudes and within this the nozzle entrance 29 forms. The distance between the nozzle inlet 29 and the inlet 25 or control member lying at an acute angle thereto 27 is less than three times or twice the inner width of the end channel 26, against which the inner width of the Entrance 29 is only slightly reduced. From the nozzle entrance 29 extends in substantially the same width in Flow direction an input channel up to one essential narrowed, shorter and cylindrical nozzle channel 30, in which the input channel has a truncated cone Section merges and its length is at most as long as its width or, on the other hand, is smaller.

Der Endkanal 30 kann am äußeren Ende und auf einem kleineren Teil seiner Länge trichterartig erweitert sein, wobei diese Erweiterung an einer freien Stirnfläche den Regner-Ausgang 11 bildet, welcher von einer verhältnismäßig schmalen, ringförmigen Abreißkante für den Strahl umgeben ist. Der Ausgang 11 kann im Radialabstand und ringförmig von einem weiteren und nach vorne weiter vorstehenden Mantel umgeben sein, dessen freies Ende am Innenumfang noch von dem aus dem Ausgang 11 austretenden Wasserstrahl berührt wird, sofern dieser etwa unter dem Kegelwinkel des Ausganges 11 aufgefächert und dadurch als Sprühstrahl ausgetragen wird. Im Eingangskanal können zur Strömungsberuhigung über den Umfang verteilte Längsrippen vorgesehen sein, welche noch einen zentralen Bereich freilassen, der mindestens der Weite des Endkanales 30 entspricht oder demgegenüber größer ist. Der Ausgang 11, der Endkananl 26, der Düseneingang 29 und der Düselkanal 30 liegen zweckmäßig koaxial zueinander in der Achse 31 des Düseneinsatzes 28, welcher nur einen einzigen Kanalabschnitt für das Fluid bildet. Der Abstand zwischen Eingang 29 und Ausgang 11 liegt etwa in der Größenordnung der Restlänge des Kanales 26.The end channel 30 can be at the outer end and on a smaller one Part of its length should be funnel-like, being this Extension of the sprinkler outlet 11 on a free end face forms, which is of a relatively narrow, annular Tear-off edge for the beam is surrounded. The exit 11 can be in the radial distance and annular from another and be further protruding coat surrounded, the free end on the inner circumference from the exit 11 escaping water jet is touched, if this is about fanned out at the cone angle of the output 11 and thereby being discharged as a spray jet. In the input channel can be distributed over the circumference to calm the flow Longitudinal ribs are provided, which still have a central one Leave the area at least the width of the end channel 30 corresponds or is larger. The exit 11, the end channel 26, the nozzle inlet 29 and the nozzle channel 30 are expediently coaxial to each other in the axis 31 of the Nozzle insert 28, which has only a single channel section forms for the fluid. The distance between entrance 29 and Output 11 is approximately in the order of the remaining length of the Channel 26

Die zwischen den Fluiddüsen 18, 19 liegende Mittel- bzw. Axialebene der Achsen 21, 22 ist mit 37 bezeichnet, während die dazu rechtwinklige Axialebene der Mittelachse 22 mit 38 bezeichnet ist und etwa durch die Mitte der Breite des Einlasses 25 geht. Eine zur Begrenzungskante des Steuersteges 27 etwa parallele Axialebene 39 der Mittelachse 22 liegt gegenüber der Axialebene 38 zur Fluiddüse 18 versetzt und gegenüber der Axialebene 38 unter einem Winkel von wenigen Graden. Der Abstand der Fluiddüse 18 gegenüber dem Einlaß 25 liegt etwa in der Größenordnung von dessen Breite oder ist demgegenüber kleiner, wobei diese Fluiddüse 18 eine Drehrichtung des Steuerrotors 20 bewirkt, die von der Fluiddüse 18 unmittelbar auf kürzestem Wege zum Einlaß 25 gerichtet ist. Die andere Fluiddüse 19 bewirkt eine entgegengesetzte Drehrichtung des Steuerrotors 20, so daß das aus ihr austretende Wasser über den größten Teil des Umfanges des Rotors 20 mitgenommen werden muß, bis es die dem Steuerglied 27 gegenüberliegende Begrenzung des Einlasses 25 erreicht. Das Steuerglied 27 deckt einen Teil des Durchlaßquerschnittes des Kanales 26 gegenüber der Kammer 17 ab, und der Einlaß 25 liegt exzentrisch zu den Achsen 21, 22 seitlich benachbart zur Mittelachse 37.The middle or between the fluid nozzles 18, 19 Axial plane of the axes 21, 22 is denoted by 37, while the right-angled axial plane of the central axis 22 with 38 is designated and approximately by the center of the width of the Inlet 25 goes. One to the boundary edge of the control web 27 is approximately parallel axial plane 39 of the central axis 22 offset from the axial plane 38 to the fluid nozzle 18 and relative to the axial plane 38 at an angle of a few Degrees. The distance of the fluid nozzle 18 from the inlet 25 is approximately in the order of its width or is in contrast, smaller, this fluid nozzle 18 is a direction of rotation of the control rotor 20 caused by the fluid nozzle 18th is directed directly to the inlet 25 by the shortest route. The other fluid nozzle 19 causes an opposite direction of rotation of the control rotor 20 so that the exiting from it Water over most of the circumference of the rotor 20 must be taken until it is the opposite of the control member 27 Limit of inlet 25 reached. The Control member 27 covers part of the passage cross section of the Channel 26 opposite the chamber 17, and the inlet 25th is eccentrically adjacent to the axes 21, 22 laterally to the central axis 37.

Der Endkanal 26 ist über den größten Teil seiner Länge zylindrisch, hat jedoch durch seine Schräglage im Bereich des Einlasses 25 rechtwinklig zu diesem liegende Querschnitte, die von der kreisrunden Form abweichen, nämlich annähernd oval sind, wobei jedoch der dem Einlaß 25 zugehörige Ovalscheitel in der Ebene der Innenseite der Stirnwand 24 etwa auf einem Drittel der Ovalhöhe abgeschnitten ist. Dadurch grenzt der Innenumfang bzw. die Kanalwand 32 des Endkanales 26 auf der dem Steuerglied 27 gegenüberliegenden Seite als zugehörige Begrenzung des Einlasses 25 im Querschnitt unter einem spitzen Winkel an die Ebene des Einlasses 25 derart an, daß die Kanalwand 32 von diesem Bereich konkav gekrümmt ausgeht und die dem Steuerglied 27 gegenüberliegende Begrenzung des Einlasses 25 im Querschnitt von spitzwinklig zueinander liegenden Flanken begrenzt ist. In entsprechender Weise geht die Kanalwand 32 auch von der zugehörigen Innenseite des Steuersteges 27 aus.The end channel 26 is over most of its length cylindrical, but due to its inclined position in the area of Inlets 25 cross sections perpendicular to this, that deviate from the circular shape, namely approximately are oval, but with the oval apex associated with inlet 25 approximately in the plane of the inside of the end wall 24 is cut off at a third of the oval height. Thereby delimits the inner circumference or the channel wall 32 of the end channel 26 on the side opposite the control member 27 as associated limit of the inlet 25 in cross section below at an acute angle to the plane of the inlet 25 such that the channel wall 32 is concavely curved from this area goes out and the limit opposite the control member 27 of the inlet 25 in cross section from each other at an acute angle lying flanks is limited. In a similar way the channel wall 32 also goes from the associated inside of the Stegsteges 27 out.

Tritt bei gesperrter Fluiddüse 19 das Wasser aus der Fluiddüse 18 aus, so gelangt es mit dem Steuerrotor 20 auf kürzestem Wege entlang der Unterseite des Steuergliedes 27 in den Bereich des Einlasses 25, wobei es gegen die dem Steuerglied 27 gegenüberliegende Begrenzung des Einlasses 25 anströmt, entlang der Kanalwandung 32 in eine sich im Endkanal 26 fortsetzende Walzenströmung überführt wird und an der Innenseite des Steuergliedes 27 so umgelenkt wird, daß es nicht wieder durch den Einlaß 25 zurück in die Steuerkammer 17 gelangen kann, sondern wiederum den gegenüberliegenden Bereich der Kanalwandung 32 anströmt. Tritt dagegen das Wasser bei gesperrter Fluiddüse 18 aus der Fluiddüse 19 aus, so treibt es zunächst den Rotor 20 an, kommt dann aber von der Leitfläche 23 frei, so daß es in die Steuerkammer 17 frei einfließen und dort in seiner Strömung beruhigt werden kann. Das Wasser strömt dann gegen den in Verlängerung der Leitfläche 23 liegenden Bereich des Innenumfanges der vollgefüllten Steuerkammer 17 und tritt beruhigt in den Einlaß 25 ein, so daß es mit im wesentlichen linearem Strömungsverhalten in den Düseneingang 29 gelangt und als Stechstrahl mit einem der Weite des Düsenkanales 30 entsprechenden Durchmesser austritt.When the fluid nozzle 19 is blocked, the water emerges from the fluid nozzle 18 out, so it comes with the control rotor 20 on the shortest Paths along the bottom of the control member 27 in the Area of the inlet 25, being against the control member 27 flows opposite limit of the inlet 25, along the channel wall 32 into one in the end channel 26 continuing roll flow is transferred and on the inside the control member 27 is deflected so that it is not back through the inlet 25 into the control chamber 17th can come, but again the opposite Flows in the area of the channel wall 32. Against that Water from the fluid nozzle 19 when the fluid nozzle 18 is blocked, it initially drives the rotor 20, but then comes from the guide surface 23 free, so that it is free in the control chamber 17 flow in and there can be calmed in its flow. The water then flows against the extension of the guide surface 23 lying area of the inner circumference of the fully filled Control chamber 17 and calmly enters the inlet 25, so that it has essentially linear flow behavior in the Nozzle entrance 29 arrives and as a jet with one of the Width of the nozzle channel 30 corresponding diameter emerges.

Im Falle der Erzeugung der Walzenströmung dagegen, tritt diese in den Düseneingang 29 ein und setzt sich bis in den Düsenkanal 30 fort, so daß das Wasser beim Eintritt in den erweiterten Ausgang 11 aufgefächert und als spitz- oder stumpfwinklig kegelförmiger Sprühstahl ausgetragen wird. Beim Betrieb mit der Fluiddüse 19 wird das Wasser auch durch den Rotor 20 über den größeren Umfangsweg zum Einlaß 25 gefördert, weil der Rotor 20 das in der Steuerkammer 17 befindliche Wasser in eine entsprechende Drehbewegung versetzt. Bei der zugehörigen Anströmung des Einlasses 25 ist das Steuerglied 27 im wesentlichen wirkungslos bzw. ist seine Wirkung so, daß es keine oder allenfalls nur eine sehr reduzierte Wirbel- bzw. Walzenströmung verursacht. Aufgrund der beiden entgegengesetzt gerichteten Anströmrichtungen im Bereich des Einlasses 25 können im Endkanal 26 auch entgegengesetzt drehende Walzenströmungen erzeugt werden, von denen eine z. B. wesentlich schwächer als die andere ist und sich daher an den Linearisierungsmitteln im Eingangskanal der Düse 28 wieder ausreichend beruhigen läßt, um im glattwandigen Düsenkanal 30 den dessen Durchmesser entsprechenden Stechstrahl zu formen. Im Falle der entgegengesetzt gerichteten stärkeren Walzenströmung bleibt diese im Kern des Eingangskanales erhalten, wobei der Kernstrom im Bereich des Einganges des Düsenkanales 30 mit dem entlang der Längstege fließenden Mantelstrom verdichtet und dadurch nochmals zusätzlich verwirbelt wird.In the case of generating the roll flow, however, occurs this into the nozzle inlet 29 and continues into the Nozzle channel 30 continues, so that the water when entering the extended output 11 fanned out and pointed or obtuse conical spray steel is discharged. At the Operation with the fluid nozzle 19, the water is also through the Rotor 20 is conveyed over the larger circumferential path to inlet 25, because the rotor 20 that in the control chamber 17 Water is set into a corresponding rotary motion. At the associated flow against the inlet 25 is the control member 27 is essentially ineffective or is its effect so that there is no or at most only a very reduced one Vortex or roller flow caused. Because of the two opposite flow directions in the area of Inlets 25 can also be opposed in the end channel 26 rotating roller flows are generated, one of which e.g. B. is much weaker than the other and therefore on the linearization means in the inlet channel of the nozzle 28 again enough to calm down in the smooth-walled Nozzle channel 30 the piercing jet corresponding to its diameter to shape. In the case of the opposite stronger roller flow remains in the core of the input channel obtained, with the core current in the area of the entrance of the nozzle channel 30 with the flowing along the longitudinal webs Sheath current is compressed and thus additionally is swirled.

Zur Umsteuerung der beiden Fluiddüsen 18, 19 ist ein Ventil 33 vorgesehen, das zweckmäßig innerhalb der Steuerkammer 14 liegt und dessen zweiarmig wippenförmiger Schließteil 34 unmittelbar auf die Einlässe der Kanalabschnitte 15, 16 dadurch wirkt, daß er dichtend gegen jeweils eine der beiden Endflächen der rohrförmigen Fortsätze anliegt und den anderen Einlaß zur Steuerkammer 14 offen freigibt. Der Schließteil 34 wird von einer Ventil-Steuerung 35 betätigt, welche ein durch die untere Stirnwand der Steuerkammer 14 nach unten frei und stabförmig ausragendes Betätigungsglied 36 aufweist. Dieses liegt seitlich benachbart zur Mittelachse 22 auf der von der Achse 21 abgekehrten Seite, so daß es mit dem Grundkörper 4 um die Achse 22 eine dem Drehwinkel entsprechende Bogenbewegung ausführt. Das Betätigungsglied 36 bewegt sich dabei zwischen manuell unabhängig voneinander einstellbaren, nicht näher dargestellten Anschlägen, welche am Sockel gelagert sind. Läuft das Betätigungsglied 36 auf einen Anschlag auf, so wird es um eine die Achse 22 und seine Längsachse etwa rechtwinklig schneidende Achse um wenige Winkelgrade geschwenkt und nimmt über eine innerhalb der Steuerkammer 14 liegende Steuerwippe das Schließglied aus der jeweils vorangegangenen Steuerstellung in die andere Steuerstellung über eine Zwischenfeder so mit, daß das Schließglied 34 federnd gegen den zugehörigen Ventilsitz gedrückt und dadurch der Fluidtritt in die Steuerkammer 17 von einer Fluiddüse 18 bzw. 19 auf die andere umgeschaltet wird. Mit den Anschlägen kann einerseits die Winkellage und andererseits die Winkelgröße des Beregnungssektors beliebig eingestellt werden.A valve is for reversing the two fluid nozzles 18, 19 33 provided, which is expedient within the control chamber 14 lies and the two-armed rocker-shaped closing part 34 directly onto the inlets of the channel sections 15, 16 acts by sealing against one of the two End faces of the tubular extensions and the other Inlet opens to the control chamber 14. The closing part 34 is actuated by a valve control 35, which by a the lower end wall of the control chamber 14 down and free Has rod-shaped protruding actuator 36. This lies laterally adjacent to the central axis 22 on the of the Axis 21 opposite side, so that it with the base body 4th around the axis 22 an arc movement corresponding to the angle of rotation executes. The actuator 36 moves between manually adjustable independently, not attacks shown in detail, which are mounted on the base are. If the actuator 36 hits a stop, so it becomes about an axis 22 and its longitudinal axis right-angled axis pivoted by a few degrees and takes over one within the control chamber 14 lying control rocker the closing member from the previous one Tax position in the other tax position an intermediate spring so that the closing member 34 resilient pressed against the associated valve seat and thereby the Fluid enters the control chamber 17 from a fluid nozzle 18 or 19 is switched to the other. With the attacks can on the one hand the angular position and on the other hand the angular size irrigation sector.

In wesentlichen alle Teile der Steuereinrichtung 10 sind auch dafür geeignet, den Antrieb der Drehbewegung des Regnerkopfes 2 zu bewirken, so daß hierfür bis auf ein mehrstufiges Getriebe keinerlei weitere Bauteile erforderlich sind. Der Steuerrotor 20 dient als Antriebsrotor für dieses Getriebe, welches zwei achsparallel gegenüber der Rotorachse 21 versetzt liegende Getriebewellen 41 mit abwechselnd ineinander greifenden Getrieberädern aufweist und in einer von der Fluidführung 13 gesonderten, trockenen Getriebekammer auf der von der Steuerkammer 14 bzw. den Fluiddüsen 18, 19 abgekehrten Seite der Achsen 21, 22 liegt. Auf dem unteren Ende einer der beiden Getriebewellen 41 ist ein Abtriebsritzel 42 angeordnet, das durch axiales Zusammenstecken des Regnerkopfes 2 mit dem Sockel in Eingriff mit dem feststehenden Laufkranz des Sockels gelangt und dadurch an diesem Laufkranz abrollt, wobei es den Regnerkopf mitnimmt. Das Ventil 33 dient auch als Umsteuerventil der Reversier-Steuerung 9, wobei durch Umschalten von einer Fluiddüse 18, 19 auf die andere die Drehrichtung des Steuerrotors 20, des Getriebes und des Abtriebritzels 42 auf Gegenlauf umgesteuert wird, so daß der Regnerkopf 5 jeweils seine Drehrichtung ändert. Dadurch wird jedes Mal am Ende jeder Drehbewegung bzw. beim Wechsel der Drehrichtung auch von einer Strahlform zur anderen gewechselt, so daß auf einem gegebenen Drehsektor zunächst in einer Drehrichtung mit der einen Strahlform und dann in der entgegengesetzten Drehrichtung mit der anderen Strahlform sowie ggfs. auf im wesentlichen gesonderten Feldern beregnet wird. Alle Bauteile, Baugruppen und Ausbildungen können statt ein einziges Mal auch in gleicher oder unterschiedlicher Ausbildung mehrfach vorgesehen sowie zu einer Baueinheit zusammengefaßt sein.Substantially all parts of the control device 10 are also suitable for driving the rotary motion of the sprinkler head 2 cause so that for this except for a multi-stage Gearbox no other components are required. The Control rotor 20 serves as a drive rotor for this transmission, which offset two axially parallel to the rotor axis 21 lying gear shafts 41 with one another alternately engaging gear wheels and in one of the Fluid guide 13 separate, dry gear chamber on the away from the control chamber 14 or the fluid nozzles 18, 19 Side of the axes 21, 22 lies. At the bottom of one of the two gear shafts 41 is an output pinion 42 arranged by axially plugging the sprinkler head 2 with the base in engagement with the fixed The rim of the base arrives at this rim rolls off, taking the sprinkler head with it. The valve 33 also serves as a reversing valve of the reversing control 9, by switching from a fluid nozzle 18, 19 to the others the direction of rotation of the control rotor 20, the transmission and the drive pinion 42 is reversed in the opposite direction, so that the sprinkler head 5 changes its direction of rotation. This means that every time at the end of each rotary movement or when Change of direction of rotation also from a jet shape to another changed so that on a given turning sector first in one direction of rotation with one beam shape and then in the opposite direction of rotation with the other Beam shape and, if necessary, on essentially separate Fields is irrigated. All components, assemblies and training can instead of once in the same or different training provided several times as well be summarized in one unit.

Es ist auch denkbar, die unterschiedlichen Strahlformen unabhängig von der Lage des Einlasses 25 dadurch zu erzeugen, daß bei einer der beiden Drehrichtungen des Steuerrotors 20 in den Weg des Wasserstromes eine Barriere ähnlich der Nase 27 oder sonstige, den Wasserstrom vor dem Eintritt in den Einlaß 25 störende Mittel, z. B. eine verstellbare Störstrahlschraube, angeordnet werden, die eine Verwirbelung des Wasserstromes bei einer der beiden Drehrichtungen bewirken. Eine andere Möglichkeit zur Erzielung unterschiedlicher Strahlformen besteht darin, das Steuerglied 20 in den beiden entgegengesetzten Bewegungsrichtungen mit unterschiedlicher Geschwindigkeit bzw. Drehzahl anzutreiben. Dies kann z. B. dadurch erreicht werden, daß die Fluiddüsen 18, 19 unterschiedliche Durchlaßquerschnitte, Radialabstände vom Steuerrotor 20 und/oder Ausrichtungen gegenüber dem Steuerrotor 20 haben. Bei der höheren Drehzahl des Steuerrotors 20 entsteht eine stärkere Verwirbelung des Wasserstromes in der Steuerkammer 17 als bei der geringeren Drehzahl, so daß einmal ein Sprühstrahl und das andere Mal ein Stechstrahl erzeugt wird. Die Justierung kann so vorgesehen sein, daß das weiter entfernt liegende Beregnungsfeld etwa gleiche oder kleinere Flächengröße wie das näher liegende Beregnungsfeld hat.It is also conceivable to use different jet shapes regardless of the position of the inlet 25 that in one of the two directions of rotation of the control rotor 20th a barrier similar to the nose in the path of the water flow 27 or other, the water flow before entering the Inlet 25 disruptive agents, e.g. B. an adjustable stray screw, be arranged, which is a swirl of the Cause water flow in one of the two directions of rotation. Another way to achieve different Beam forms is the control member 20 in the two opposite directions of movement with different To drive speed or speed. This can e.g. B. can be achieved in that the fluid nozzles 18, 19 different Passage cross sections, radial distances from the control rotor 20 and / or orientations with respect to the control rotor 20 to have. At the higher speed of the control rotor 20 arises a stronger swirling of the water flow in the control chamber 17 than at the lower speed, so that once Spray jet and the other time a pricking jet is generated. The adjustment can be provided so that it continues remote irrigation field about the same or smaller Area size as the closer irrigation field has.
