Definitions

Thereafter, these rays can be fanned out or divided by disruptive elements or the like. If the rotation or another movement of the guide body transversely to the water jet is too fast, it will be too much scattered and the range of action will decrease accordingly. If the movement speed depends on the pressure of the tap water supplied to the sprinkler, these disadvantages increase with the water pressure.
  • GB-A-2 166 669 shows sprinklers comprising either free-flow guide bodies or guide bodies which are driven synchronously without relative movement. Control means for changing the throwing arc of the exiting water jet are not provided within the sprinkler.

  • both guide bodies continuously execute a respectively rectified or continuous or other working movement relative to a base or main body of the sprinkler.
  • the upstream guide body or water jet parts have a much lower and possibly zero moving speed than the immediately following guide body, which takes over the water jets directly from the upstream guide body.
  • This downstream guide body has the last surfaces, which can be acted upon by the water before it is released from the sprinkler in the trajectory.
  • the movement of the downstream guide body can be at least 10 to 20 or. be at least 30 or 40 times faster than the upstream guide body.

Abstract

The sprinkler has a vertical mounting with a water flow driven turbine (8) which rotates faster than a direct driven rotor using a gearing (9) to step up the rotational speed. A water flow divider (7) with shaped contour spreads the water flow while the fast rotating head provides an added sprinkling effect. The spreading effect is adjustable by a rotating sleeve control (5). This adjusts the range of the sprinkling. The rotating drive provides a fast rotation even with low water pressures. The gearing includes eccentric gears.

Description

Die Erfindung betrifft einen Regner nach den. Oberbegriff des Patentanspruchs 1, wie er auch aus der CH-05-187948 bekannt ist. Mit dem Regner kann eine Flüssigkeit, insbesondere Wasser, in einer Wurfbahn so ausgebracht werden, daß ein verhältnismäßig großes, z.B. viele Quadratmeter messendes Feld durch Niederschlag bewässert wird. Das Fluid wird zweckmäßig etwa horizontal bzw. schräg nach oben gerichtet vom Fluidausgang ans Freie abgegeben und gelangt dann unter der Austragenergie über eine gekrümmte Wurfbahn auf den Boden.The invention relates to a sprinkler according to the. The preamble of claim 1, as it is also known from CH-05-187948. With the sprinkler, a liquid, in particular water, can be applied in a trajectory so that a relatively large, e.g. many square meters of field being watered by precipitation. The fluid is expediently emitted approximately horizontally or obliquely upward from the fluid outlet to the free and then passes under the discharge energy via a curved trajectory on the ground.

Der Regner ist als Kreisregner ausgebildet, welcher durch einen oder mehrere rotierende bzw. feststehende Leitkörper das Wasser in einem Kreisbogen um sich verteilt, wobei der Kreisbogen einen Bogen- bzw. Sektorenwinkel von weniger, als 360° z.B. höchstens 45°, hat. Das Wasser wird während des Verlassens des Regners durch die Leitkörperanordnung aufgefächert, nämlich z.B. zuerst in nutartigen Leitkanälen zu einzelnen sowie in Bogenrichtung benachbarten, gesonderten Wasserstrahlen aufgeteilt bzw. aufgefächert. Danach können diese Strahlen durch Störglieder oder dgl. nochmals in sich aufgefächert bzw. geteilt werden. Ist dabei die Drehung oder eine andere Bewegung des Leitkörpers quer zum Wasserstrahl zu schnell, so wird dieser zu sehr zerstreut und die Reich- bzw. Wurfweite nimmt entsprechend ab. Ist dabei die Bewegungsgeschwindigkeit abhängig vom Druck des dem Regner zugeführten Leitungswassers, so steigen diese Nachteile mit dem Wasserdruck.The sprinkler is designed as a circular sprinkler which, by means of one or more rotating guide bodies, distributes the water around it in a circular arc, the circular arc having a bow or sector angle of less than 360 °, for example. at most 45 °, has. The water is fanned out during the exit of the sprinkler by the baffle arrangement, e.g. first divided into groove-like Leitkanälen to individual and adjacent in the arc direction, separate water jets or fanned. Thereafter, these rays can be fanned out or divided by disruptive elements or the like. If the rotation or another movement of the guide body transversely to the water jet is too fast, it will be too much scattered and the range of action will decrease accordingly. If the movement speed depends on the pressure of the tap water supplied to the sprinkler, these disadvantages increase with the water pressure.

Die GB-A-2 166 669 zeigt Regner, die entweder frei durch den Wasserfluß rotierende Leitkörper oder solche Leitkörper umfassen, welche ohne Relativbewegung gleichlaufend angetrieben sind. Steuermittel zur Veränderung des Wurfbogens des austretenden Wasserstrahles sind innerhalb des Regners nicht vorgesehen. Die Leitflanken der Leitkörper sind im Querschnitt eben, nämlich durch Nuten gebildet, welche über ihre gesamte Länge und Tiefe konstante Breite haben.
Ein weiterer Regner ist aus der EP-A-339 966 bekannt.
GB-A-2 166 669 shows sprinklers comprising either free-flow guide bodies or guide bodies which are driven synchronously without relative movement. Control means for changing the throwing arc of the exiting water jet are not provided within the sprinkler. The guide flanks of the guide body are flat in cross section, namely formed by grooves which have constant width over their entire length and depth.
Another sprinkler is known from EP-A-339 966.

Der Erfindung liegt auch die Aufgabe zugrunde einen Regner zu schaffen, bei welchem Nachteile bekannter Ausbildungen oder der beschriebenen Art vermieden sind und der insbesondere wenigstens teilweise unabhängig vom zugeführten Wasserdruck einen hohen Wirkungsgrad bzw. genau bestimmbar eine große Beregnungsdichte sowie eine große Beregnungsweite auf unterschiedlich großen Beregnungssektoren gewährleistet.The invention is also based on the object to provide a sprinkler in which disadvantages of known embodiments or the type described are avoided and in particular at least partially independent of the supplied water pressure high efficiency or accurately determinable a large irrigation density and a large irrigation range on different sized irrigation sectors guaranteed.

Erfindungsgemäß sind die Merkmale nach Patenanspruch 1 vorgesehen. Es können zwei die Strömung des Fluids beeinflussende Körper bzw. Flächen im annäherend gleichförmig fortdauernden Austragbetrieb eine Relativbewegung zueinander haben. Es ergeben sich ständig ändernde Relativstellungen der beiden Körper zueinander. Der oder die Wasserstrahlen werden beim Verlassen des Regners ständig wechselnd anders aufgefächert bzw. zerstreut. Die Geschwindigkeit der Relativbewegung kann im konstanten Austragbetrieb und/oder in der Anlaufphase etwa konstant bzw. frei von schlagartigen Änderungen sein.According to the features of claim 1 are provided. Two bodies or surfaces influencing the flow of the fluid may have a relative movement relative to one another in the approximately uniformly continuing discharge operation. This results in constantly changing relative positions of the two bodies to each other. The or the water jets are constantly fanned or scattered differently when leaving the sprinkler. The speed of the relative movement can be approximately constant or free from abrupt changes in the constant discharge operation and / or in the start-up phase.

Besonders zweckmäßig ist es, wenn beide Leitkörper gegenüber einem Sockel bzw. Grundkörper des Regners laufend eine jeweils gleichgerichtete bzw. kontinuierliche oder andere Arbeitsbewegung ausführen. Der vorgeschaltete Leitkörper bzw. Wasserstrahl-Teile haben eine wesentlich geringere sowie ggf. gegen Null gehende Bewegungsgeschwindigkeit als der unmittelbar nachfolgende Leitkörper, welcher die Wasserstrahlen unmittelbar von dem vorgeschalteten Leitkörper übernimmt. Dieser nachgeschaltete Leitkörper weist die letzten Flächen auf, welche vom Wasser beaufschlagt werden können, bevor es vom Regner in die Wurfbahn freikommt. Die Bewegung des nachgeschalteten Leitkörpers kann mindestens 10- bis 20-bzw. wenigstens 30- oder 40-fach schneller als die des vorgeschalteten Leitkörpers sein. Letzterer gibt den jeweiligen Wasserstrahl relativ stark gebündelt ab, und der nachgeschaltete Leitkörper wird verhältnismäßig energiestark beaufschlagt bzw. von den Wasserstrahlen angetrieben. Die Wasserstrahlen können dabei am vorgeschalteten Leitkörper so geführt werden, daß sie auf diesen durch Rückstoß ein Antriebsmoment im Sinne seiner Arbeitsbewegung ausüben, wodurch der Wirkungsgrad noch weiter erhöht wird. Es können mehr als zwei einander in Strömungsrichtung nachgeordnete, sich gegenüber dem Grundkörper ständig oder intermetierend bewegende Leitkörper z.B. der beiden genannten Arten vorgesehen sein. Es ist auch vorteilhaft, nur zwei Leitkörper in einem den bzw. die Fluidausgänge bildende Austragkopf zusammenzufassen.It is especially expedient if both guide bodies continuously execute a respectively rectified or continuous or other working movement relative to a base or main body of the sprinkler. The upstream guide body or water jet parts have a much lower and possibly zero moving speed than the immediately following guide body, which takes over the water jets directly from the upstream guide body. This downstream guide body has the last surfaces, which can be acted upon by the water before it is released from the sprinkler in the trajectory. The movement of the downstream guide body can be at least 10 to 20 or. be at least 30 or 40 times faster than the upstream guide body. The latter gives the respective water jet bundled relatively strong, and the downstream guide body is relatively energized acted upon or driven by the water jets. The water jets can be performed on the upstream guide body so that they exert on this by recoil a drive torque in the sense of his working movement, whereby the efficiency is further increased. More than two guide bodies arranged downstream of one another in the flow direction and moving constantly or intermittently with respect to the main body may be used, for example. be provided of the two types mentioned. It is also advantageous to combine only two guide bodies in a discharge head forming the fluid outlet or outlets.

Zweckmäßig treibt ein Leitkörper einen weiteren Leitkörper an oder bestimmt zumindest dessen Bewegungsgeschwindigkeit, z.B. dadurch, daß die beiden Leitkörper miteinander antriebsverbunden sind. Der getriebene Leitkörper kann dabei ebenfalls ein Antriebsmoment erzeugen. Zur Antriebsverbindung ist ein Zahnrad-Getriebe, insbesondere ein kompaktes, nur zwei Abwälzbereiche aufweisendes Untersetzungsgetriebe vorgesehen, das den einen Leitkörper etwa fünfzigmal langsamer bewegen läßt als den anderen. Die Abwälzbereiche können teilweise oder vollständig innerhalb des nachgeordneten Leitkörpers, z.B. eines Turbinenrades liegen, welches den weitesten Bereich des Austragkopfes bildet und von dessen wasserbeaufschlagten Treibflächen bzw. Turbinenschaufeln das Wasser in die freie Wurfbahn gelangt.Suitably, a guide body drives a further guide body or determines at least its movement speed, for example, characterized in that the two guide bodies are drivingly connected to each other. The driven guide body can also generate a drive torque. For drive connection, a gear transmission, in particular a compact, only two Abwälzbereiche exhibiting reduction gear is provided, which can move one guide body about fifty times slower than the other. The Abwälzbereiche may partially or completely within the downstream guide body, eg one Turbine wheels are located, which forms the widest region of the discharge head and from the water-loaded propulsion surfaces or turbine blades, the water enters the free trajectory.

Auch unabhängig von der beschriebenen Ausbildung können Mittel vorgesehen sein, um durch eine Stellbewegung den beregneten Sektor reversibel hinsichtlich der Wurfweite und/oder der Wurfbreite zu vergrößern bzw. zu verkleinern, insbesondere ohne daß hierzu Teile entfernt bzw. Bauteile hinzugefügt werden müssen. Auch andere Eigenschaften des Fluidstrahles können damit veränderbar sein.Regardless of the described training means may be provided to increase the shrunken sector reversible in terms of throwing distance and / or the throwing width by an actuating movement or to reduce, in particular without the need for parts removed or added components. Other properties of the fluid jet can thus be changed.

Zwischen dem Fluideingang und dem Fluidausgang des Regners an dem die Lagerung für den jeweiligen Steuer- bzw. Leitkörper feststehend aufnehmenden Grundkörper ist vorteilhaft eine Stellvorrichtung angeordnet. Mit dieser können Verstellungen von Hand auch während des Austragbetriebes von einem Benutzer vorgenommen werden, ohne daß dieser sich den austretenden Wasserstrahlen aussetzt. Die Stellvorrichtungweist vorteilhaft eine Steuerfläche mit zueinander unmittelbar benachbarten, unterschiedlich gro-βen Steueröffnungen und eine gegenüber diesen bewegbare Steuerfläche zum graduellen teilweisen oder vollständigen Schließen der jeweiligen Steueröffnung auf. Die Steueröffnungen können in Richtung der Steuerbewegung wenigstens an einer Begrenzung etwa gleiche Breite bzw. quer zur Steuerbewegung abgestuft unterschiedliche Quererstreckungen haben. Statt einer auch denkbaren mehrteiligen Schließfläche mit gegeneinander bewegbaren Flächenteilen genügt eine einteilige Schließfläche mit gemeinsam bewegbaren Flächenteilen, um die jeweilige Steueröffnung vollständig bzw. auf voller Weite zu öffnen, vollständig zu schließen oder nur auf einem Teil ihrer Quererstreckung zu schließen. Dadurch kann die Summe der geöffneten Durchlaßquerschnitte der Steueröffnungen bei mindestens zwei bis allen unterschiedlichen Einstellungen etwa konstant sein, so daß sich entsprechend konstante Druckverhältnisse bzw. Durchflußmengen ergeben.Between the fluid inlet and the fluid outlet of the sprinkler on the bearing for the respective control or guide body fixedly receiving base body is advantageously arranged an adjusting device. With this adjustments can be made by hand even during the discharge operation by a user, without this exposes itself to the exiting water jets. The actuating device advantageously has a control surface with mutually directly adjacent, differently sized control openings and a control surface movable relative thereto for the gradual partial or complete closing of the respective control opening. The control openings may have different transverse extensions in the direction of the control movement at least at a boundary approximately equal width or transversely to the control movement. Instead of a conceivable multi-part closing surface with mutually movable surface parts is sufficient a one-piece closing surface with jointly movable surface parts to fully open the respective control opening or full width, close completely or close only on a part of its transverse extent. As a result, the sum of the open flow cross-sections of the control openings can be approximately constant at at least two to all different settings, so that correspondingly constant pressure conditions or flow rates result.

Die erfindungsgemäße Ausbildung ist sowohl für axial feststehend aufzustellende Regner als auch für Versenkregner geeignet, bei welchen der Austragkopf bzw. der Grundkörper an einem Träger axial bzw. in Höhenrichtung aus- und einfahrbar gelagert ist, z.B. unter der Wirkung des Druckes des zugeführten Wassers. Auch die Stellmittel sind zweckmäßig an der verfahrbaren Einheit vorgesehen, insbesondere unmittelbar unterhalb des Austragkopfes so, daß das Wasser die Handhabe durchströmt und sie an ihrer Oberseite im wesentlichen berührungsfrei verläßt, nämlich durch den vorgeschalteten Leitkörper geführt ist.The construction according to the invention is suitable both for axially fixed sprinklers and for pop-up sprinklers, in which the discharge head or the base body is mounted on a support axially or in the vertical direction extendable and retractable, e.g. under the effect of the pressure of the water supplied. The adjusting means are expediently provided on the movable unit, in particular directly below the discharge head so that the water flows through the handle and leaves it at its top substantially non-contact, namely guided by the upstream guide body.

Der Regner 1 gemäß den Zeichnungen weist einen hülsen- oder rohrförmigen zylindrischen Grundkörper 2 auf. Dieser ist teleskopartig bewegbar in einem schachtförmig oder ähnlich ausgebildeten, jedoch weiteren Träger 3 mit einem Ende bewegbar gelagert. Am anderen, oberen Ende trägt er einen Austrag-Kopf 4 für den Austrag des Wassers. Unmittelbar benachbart zu dem über den Rohrabschnitt des Grundkörpers 2 vorstehenden Kopf 4 ist axial benachbart zum Rohrabschnitt eine Stellvorrichtung 5 zur Veränderung von Austragscharakteristika vorgesehen. Diese ist mit einer hülsenförmigen Handhabe 6 etwa gleichen Außenquerschnittes wie der Rohrabschnitt des Grundkörpers 2 einzustellen und bildet eine kontinuierliche Fortsetzung des Rohrabschnittes annähernd bis zur Unterseite des Kopfes 4.The sprinkler 1 according to the drawings has a sleeve-shaped or tubular cylindrical base body 2. This is telescopically movable in a shaft-like or similar, but further support 3 movably mounted with one end. At the other, upper end he carries a discharge head 4 for the discharge of water. Immediately adjacent to the over the pipe section of the body 2 projecting head 4, an adjusting device 5 is provided for changing discharge characteristics axially adjacent to the pipe section. This is to set with a sleeve-shaped handle 6 approximately the same outer cross-section as the pipe section of the body 2 and forms a continuous continuation of the pipe section approximately to the bottom of the head 4th

Der Kopf 4 weist einen ersten Leitkörper 7 und einen zweiten Leitkörper 8 auf. Diese sind etwa achsparallel bzw. achsgleich und mit ihren einander zugekehrten Enden ineinandergreifend angeordnet. Sie bilden aneinanderschließende Längsabschnitte von Wasserführungen. Die beiden Leitkörper 7, 8 sind über ein Zahnrad-Getriebe 9, miteinander verbunden. Dieses liegt wie die Leitkörper 7, 8 etwa in der Achse 10 wenigstens einer der Einheiten 2 bis 8. Diese Achse 10 ist im Betrieb meist etwa vertikal ausgerichtet. Das Wasser wird über einen am unteren Ende der Einheit 2 und/oder 3 vorgesehenen Fluideingang 11 z.B. über einen zerstörungsfrei lösbar angeschlossenen Schlauch zugeführt. Es durchströmt nacheinander die Einheiten 5 bis 8 und verläßt den Kopf 4 im Bereich eines durch die Außenumfänge beider Leitkörper 7, 8 gebildeten Fluidausganges 12. Das Wasser wird dem Leitkörper 7 durch eine Verteil- bzw. Richtdüse 13 zugeführt, welche bestimmt, auf welchem stationären Bogenwinkel den Leitkörpern 7, 8 Wasser zugeführt wird.The head 4 has a first guide body 7 and a second guide body 8. These are approximately parallel to the axis or the same axis and arranged with their ends facing each other interlocking. They form contiguous longitudinal sections of water ducts. The two guide bodies 7, 8 are connected to each other via a gear transmission 9. This is like the guide body 7, 8 approximately in the axis 10 at least one of the units 2 to 8. This axis 10 is usually aligned approximately vertically in operation. The water is introduced via a fluid inlet 11 provided at the lower end of the unit 2 and / or 3, e.g. supplied via a nondestructive releasably connected hose. It flows through the units 5 to 8 in succession and leaves the head 4 in the region of a fluid outlet 12 formed by the outer peripheries of both guide bodies 7, 8. The water is supplied to the guide body 7 through a distribution nozzle 13, which determines which stationary one Arc angle the guide bodies 7, 8 water is supplied.

Der Leitkörper 7 weist mit ihren unteren Enden an die Düse 13 angeschlossene Leitflächen 14 auf, welche durch entsprechende Formgebung das nach oben strömende Wasser mit zunächst zunehmender und dann konstanter Steigung spitzwinklig nach außen weg von der Achse 10 umlenken, so daß es den Leitkörper 7 unter etwa 45° schräg nach oben gerichtet verläßt. Die um die Achse 10 gleichmäßig verteilten Leitflächen 14 sind seitlich von rippenartigen Vorsprüngen bzw. Schaufeln 15 begrenzt, welche wie die Leitflächen gemäß Fig. 2 vom Zufluß- bis zum Austrittsende um eine geringe Wendelsteigung von wenigen Winkelgraden um die Achse 10 gleichsinnig so schräg gestellt sind, daß das unter Druck durchfließende Wasser auf den Leitkörper 7 ein Antriebsmoment um die Achse 10 bewirkt. Auch der Leitkörper 15 weist entsprechende, jedoch zur Achse 10 etwa parallele und gegen das Eintrittsende des Leitkörpers 7 frei ausragende Turbinenschaufeln 16 auf, gegen welche das aus dem Leitkörper 7 austretende Wasser unter Bewirkung eines Antriebsmomentes strömt, das um die Achse 10 gleichgerichtet zu dem genannten Antriebsmoment des Leitkörpers 7 ist. Ein Teil jedes Wasserstrahles kann dabei unter Umgehung des Leitkörpers 8 bzw. der Schaufel 16 aus dem Leitkörper 7 direkt in die Wurfbahn austreten, während der andere Teil den Leitkörper 8 ausreichend antreibt.The guide body 7 has with its lower ends to the nozzle 13 connected guide surfaces 14, which by appropriate shaping the upwardly flowing water with an initially increasing and then constant pitch at an acute angle to the outside deflect from the axis 10 so that it leaves the guide body 7 directed at about 45 ° obliquely upward. The evenly distributed around the axis 10 baffles 14 are bounded laterally by rib-like projections or blades 15 which are like the baffles of FIG. 2 from Zufluß- to the exit end by a small helical pitch of a few degrees about the axis 10 in the same direction inclined in that the water flowing through under pressure on the guide body 7 causes a drive torque about the axis 10. Also, the baffle 15 has corresponding but approximately parallel to the axis 10 and against the inlet end of the guide body 7 projecting freely turbine blades 16, against which the emerging from the guide body 7 water flows causing a drive torque, which is rectified about the axis 10 to said Drive torque of the guide body 7 is. A portion of each jet of water can escape, while bypassing the guide body 8 or the blade 16 from the guide body 7 directly into the trajectory, while the other part sufficiently drives the guide body 8.

Zur Lagerung der jeweiligen Einheit 4 bis 9 ist ein Halteglied, z.B. ein Bolzen oder Dorn 17 vorgesehen, der mit seinem Schaftende in einer innerhalb der Handhabe 6 liegenden, hülsenförmigen Konsole des Grundkörpers 2 festsitzend gehaltert ist, wobei die Konsole axial benachbart zum Rohrabschnitt des Grundkörpers 2 liegt und mit diesem einteilig über Radial- und/oder Axialrippen verbunden ist. Benachbart sowie im Anschluß zur oberen Stirnfläche der Konsole ist der Dorn 17 von einer feststehenden Lagerhülse 18 umgeben, an deren von der Konsole abgekehrten Ende der Kopf des Domes 17 verspannt anliegt, so daß die Lagerhülse 18 gegenüber dem Grundkörper 2 radial- und/oder axialspielfrei angeordnet ist bzw. eine Fortsetzung der hülsenförmigen Konsole bildet. Die Leitkörper 7, 8 sind mit axial unmittelbar benachbarten, annähernd gleich dimensionierten Lagern 19, 21 unabhängig voneinander auf dem Außenumfang der Lagerhülse 18 bzw. jeweils mit einer hülsenförmigen Nabe 22, 23 drehbar gelagert, wobei jedoch der Außenumfang der Nabe 23 des Leitkörpers 8 exzentrisch zur Achse 10 in der dazu parallelen Achse 20 liegt. Das Maß der Exzentrizität ist wesentlich kleiner als der Radius der Nabe 23 bzw. der Lagerflächen 19, 21.For storage of the respective unit 4 to 9, a holding member, e.g. a bolt or mandrel 17 is provided, which is fixedly held with its shaft end in a lying within the handle 6, sleeve-shaped bracket of the base body 2, wherein the console is axially adjacent to the pipe section of the base body 2 and with this integrally via radial and / or axial ribs connected is. Adjacent and in connection to the upper end face of the bracket of the mandrel 17 is surrounded by a fixed bearing sleeve 18, clamped against the console facing away from the end of the head of the dome 17, so that the bearing sleeve 18 relative to the base body 2 radially and / or axial play is arranged or forms a continuation of the sleeve-shaped console. The guide bodies 7, 8 are rotatably mounted with axially immediately adjacent, approximately equal dimensioned bearings 19, 21 independently of each other on the outer circumference of the bearing sleeve 18 and respectively with a sleeve-shaped hub 22, 23, but the outer circumference of the hub 23 of the guide body 8 eccentric to the axis 10 in the axis 20 parallel thereto. The extent of the eccentricity is substantially smaller than the radius of the hub 23 and the bearing surfaces 19, 21st

Der Leitkörper 7 weist einen am Außenumfang wenigstens teilweise annähernd spitzwinklig konisch in Strömungsrichtung erweiterten, geschlossenen Mantel 24 auf, an dessen Außenumfang die Leitflächen 14 bzw. die einteilig mit ihm ausgebildeten Schaufeln 15 liegen. Die kleinste Außenweite des Mantels 24 im Bereich der Düse 13 ist etwa gleich der Außenweite der Lagerhülse 18 bzw. der Lagerfächen 19, 21, während die am anderen Ende vorgesehene größte Weite größer als die axiale Länge des Mantels 24 ist, welcher an diesem Ende einen zylindrischen, in einen Mantel 25 des Leitkörpers 8 eingreifenden Endabschnitt aufweisen kann. Dieser Mantel 25 ist innen und/oder außen annähernd zylindrisch und hat eine Länge, die wesentlich kleiner als die Hälfte seiner Weite ist. Die freie, untere Stirnfläche des Mantels 25 bildet eine entsprechend den Auslaßenden der Leitflächen 14 schräg gestellte Fortsetzung dieser Leitflächen, über welche die Leitschaufeln 16 axial frei ausragend vorstehen, wobei sie nicht über den Innenumfang vorstehen, sondern bündig mit diesem abschließen und entlang des Außenumfanges bis zu einer Stirnwand 26 geführt sind, von welcher der Mantel 25 axial frei absteht. Die Stirnwand 26 bzw. ein diese abdeckender Deckel bildet die oberste Endfläche des Kopfes 4, wobei der Kopf des Domes 17 an der Stirnwand 26 so anliegt, daß dadurch die Leitkörper 7, 8 und Drehläufer des Getriebes 9 axial gegenüber dem Grundkörper 2 gemeinsam formschlüssig gesichert sind. Die Schaufeln 16 bilden Versteifungsrippen für den Mantel 25 und sind ihrerseits durch diesen verstärkt, wobei die Anzahl der gleichmäßig um die Achse 10 verteilten Schaufeln 15, 16 der beiden Leitkörper 7, 8 etwa gleich sein kann.The guide body 7 has a jacket 24 which is conically widened in the direction of flow at least approximately approximately at an acute angle and has a closed jacket 24 on the outer circumference of which are the guide surfaces 14 or the blades 15 formed integrally therewith. The smallest outer width of the jacket 24 in the region of the nozzle 13 is approximately equal to the outer width of the bearing sleeve 18 and the Lagerfächen 19, 21, while provided at the other end largest width is greater than the axial length of the jacket 24, which at this end a cylindrical, may have in a jacket 25 of the guide member 8 engaging end portion. This jacket 25 is approximately cylindrical inside and / or outside and has a length which is substantially smaller than half its width. The free, lower end face of the shell 25 forms a corresponding to the outlet ends of the baffles 14 obliquely continued continuation of these baffles over which the vanes 16 protrude freely projecting axially, they do not protrude beyond the inner circumference, but flush with this and complete along the outer circumference to are guided to an end wall 26, from which the jacket 25 protrudes axially freely. The end wall 26 or a cover covering this forms the uppermost end face of the head 4, wherein the head of the dome 17 rests against the end wall 26 so that thereby the guide body 7, 8 and turn the gear 9 secured axially against the base body 2 together form-fitting manner are. The blades 16 form stiffening ribs for the shell 25 and in turn are reinforced by this, wherein the number of evenly distributed around the axis 10 blades 15, 16 of the two guide body 7, 8 may be approximately equal.

Die Enden der nutförmigen Leitflächen 14 bilden eine entsprechende Anzahl, z.B. mindestens acht oder zehn bzw. höchstens vierzehn oder achtzehn radial nach außen gerichtete Wasseraustritte 27, welche auf einem Teil ihrerAxialerstreckung im Vorbeilauf durch die Schaufeln 16 axial überdeckt werden und von diesen nur durch einen kleinsten axialen Spalt 28, nämlich ein kleines Radialspiel getrennt sind. Vom Austritt 27 tritt das Wasser zwischen benachbarte Schaufeln 16 bzw. gegen deren radial innere Axialkanten aus, wobei die Schaufeln 16 in Axialansicht radial nach innen spitzwinklig keilförmig bzw. schneidenartig verjüngt sein können, so daß der Wasserstrahl durch die Schneide und entlang der Flanken der Schaufel 16 geteilt wird, wenn diese den Strahl durchläuft. Befindet sich gerade keine Schaufel 16 im Bereich eines austretenden Wasserstrahles, so gelangt dieser ungehindert bzw. ungeteilt in die Wurfbahn. Im anderen Fall verläßt das Wasser den Kopf 4 im Bereich von Austritten 29, welche in einer die radial äußeren Seiten der Schaufeln 16 berührenden zylindrischen Hüllfläche liegen, deren Durchmesser nur etwa um die Breite der Schaufeln 16 größer als die entsprechende Hüllfläche der Austritte 27 ist. Im Bereich der Austritte 29 löst sich das Wasser vollständig vom Kopf 4.The ends of the groove-shaped vanes 14 form a corresponding number, e.g. at least eight or ten, or at most fourteen or eighteen radially outwardly directed water outlets 27, which are axially covered on a part of their axial extension in passing by the blades 16 and are separated from them only by a smallest axial gap 28, namely a small radial clearance. From the outlet 27, the water exits between adjacent blades 16 and against the radially inner axial edges, wherein the blades 16 may be tapered in an acute angle wedge-shaped or blade-like in axial view radially inwardly, so that the water jet through the blade and along the flanks of the blade 16 is divided as it passes through the beam. If there is no blade 16 in the region of an exiting water jet, then it passes unhindered or undivided into the trajectory. In the other case, the water leaves the head 4 in the region of outlets 29, which lie in a radially outer sides of the blades 16 touching cylindrical envelope surface whose diameter is only about the width of the blades 16 is greater than the corresponding envelope surface of the outlets 27. In the area of the outlets 29, the water dissolves completely from the head of the fourth

Die Leitkörper 7, 8 begrenzen einen Getrieberaum 30, welcher durch axiales Auseinanderziehen der beiden Leitkörper 7, 8 in einfacher Weise zu öffnen ist, wenn zuvor der Dorn 17 zerstörungsfrei gelöst worden ist. Der Getrieberaum 30 wird am Umfang nurvom Mantel 25, an der oberen Stirnseite von der Stirnwand 26 und nur an der unteren, gegenüberliegenden Stirnseite durch den Leitkörper 7 begrenzt. In dem Getrieberaum 30 sind ineinander verschachtelt drei erste, zweite und dritte Getriebeglieder 31, 32, 33 angeordnet, welche über Zahnkränze 34, 35, 36 ineinandergreifen. Das erste, als Außenläufer ausgebildete treibende oder bremsende Getriebeglied 31 ist mit einer Nabe 37 um die Achse 20 auf dem Außen umfang der Nabe 23 drehbar gelagert und liegt mit einer ringscheibenförmig die Nabe 37 mit einem Mantel 39 verbindenden Stirnwand 38 unmittelbar benachbart zur Stirnwand 26. Am Innenumfang des gegen den Leitkörper 7 frei ausragenden Mantels 39 ist der zugehörige, in der Achse 20 liegende Zahnkranz 34 angeordnet, wobei die Achse 20 im Betrieb um die Achse 10 rotiert, weil durch die exzentrische Lagerung ein Kurbeltrieb 40 gebildet ist, über welchen das Getriebeglied 31 durch den Leitkörper 8 bzw. einen anderen Rotor angetrieben wird.The guide body 7, 8 delimit a gear chamber 30, which can be opened by axially pulling apart the two guide body 7, 8 in a simple manner, if previously the mandrel 17 has been solved nondestructive. The gear housing 30 is bounded on the periphery only by the jacket 25, on the upper end side of the end wall 26 and only on the lower, opposite end side by the guide body 7. In the gear housing 30, three first, second and third gear members 31, 32, 33 are interleaved with each other, which mesh with each other via sprockets 34, 35, 36. The first, designed as an external rotor driving or braking gear member 31 is provided with a hub 37 to the Axis 20 rotatably mounted on the outer circumference of the hub 23 and is located with an annular disc hub 37 with a shell 39 connecting end wall 38 immediately adjacent to the end wall 26. On the inner circumference of the against the guide body 7 freely projecting jacket 39 is the associated, in the axis 20 lying toothed rim 34 is arranged, wherein the axis 20 rotates in operation about the axis 10, because by the eccentric bearing a crank mechanism 40 is formed, via which the gear member 31 is driven by the guide body 8 and another rotor.

Das zweite Getriebeglied 32 dieser nach Art eines Planetengetriebes ausgebildeten Getriebestufe ist als Stator feststehend mit dem Grundkörper 2 bzw. der Lagerhülse 18 verbunden und kann mit dieser einteilig ausgebildet sein. Dieses napfförmige Getriebeglied 32 liegt mit seiner Stirnwand zwischen den Lagern 19, 21, weist einen gegen die Stirnwand 38 gerichteten Mantel und unmittelbar benachbart zur Stirnwand 38 einen radial nach außen abstehenden Ringbund mit dem zugehörigen Zahnkranz 35 am Außenumfang auf. Der Zahnkranz 34 steht daher nach Art eines Planetenläufers nur in einem sehr begrenzten Umfangsbereich in Eingriff mit dem in der Achse 10 liegenden Zahnkranz 35 bzw. dem Zahnkranz 36, welcher axial unmittelbar benachbart zum Zahnkranz 35 in den Zahnkranz 34 eingreift und als Außenverzahnung am Außenumfang des Getriebegliedes 33 vorgesehen ist.The second gear member 32 of this formed in the manner of a planetary gear stage is fixedly connected as a stator to the base body 2 and the bearing sleeve 18 and may be integrally formed therewith. This cup-shaped gear member 32 is located with its end wall between the bearings 19, 21, has a directed against the end wall 38 shell and immediately adjacent to the end wall 38 a radially outwardly projecting annular collar with the associated sprocket 35 on the outer circumference. The ring gear 34 is therefore in the manner of a planetary rotor only in a very limited peripheral area in engagement with the lying in the axis 10 ring gear 35 and the ring gear 36 which axially adjacent to the ring gear 35 engages the ring gear 34 and external teeth on the outer circumference of the Gear member 33 is provided.

Dieses hülsenförmige Getriebeglied 33 kann einteilig mit dem Mantel 24 ausgebildet sein, liegt mit Radialabstand innerhalb des Mantels 24 und steht axial über dessen Ende bzw. weiter als die Nabe 22 vor, welche wie die Nabe 23 axial gegen die Stirnwand des Getriebegliedes 32 abgestützt ist. Die gegeneinander weisenden Endflächen der Mäntel 24, 39 liegen unmittelbar benachbart zueinander und der Außenumfang des Getriebegliedes 31 bzw. Mantels 39 reicht annähernd bis an den Innenumfang des Mantels 25, so daß sich eine radial und axial sehr kompakte Ausbildung ergibt. Die Zähnezahlen der Zahnkränze 34 bis 36 können verschieden sein, z.B. um einen Zahn, wobei die Außenverzahnung 36 weniger Zähne als die Außenverzahnung 35 bzw. die Innenverzahnung 34 haben kann. Der aufgrund der unterschiedlichen Zähnezahl der Außenverzahnungen 35 und 36 entstehende unterschiedliche Achsabstand zur Innenverzahnung 34 wird durch Profilverschiebung in bekannter Weise ausgeglichen, so daß beide Außenverzahnungen 35 und 36 den gleichen Achsabstand zur Innenverzahnung 34 erhalten.This sleeve-shaped gear member 33 may be integrally formed with the jacket 24, is located at a radial distance within the shell 24 and projects axially beyond the end or further than the hub 22 which, like the hub 23 axially against the end wall of the gear member 32 is supported. The mutually facing end surfaces of the shells 24, 39 are immediately adjacent to each other and the outer circumference of the gear member 31 and shell 39 extends approximately to the inner periphery of the shell 25, so that there is a radially and axially very compact design. The numbers of teeth of sprockets 34 to 36 may be different, e.g. around a tooth, wherein the external teeth 36 may have fewer teeth than the external teeth 35 and the internal teeth 34. The resulting due to the different number of teeth of the external teeth 35 and 36 different center distance to the internal teeth 34 is compensated by profile displacement in a known manner, so that both external teeth 35 and 36 receive the same center distance to the internal teeth 34.

Das Untersetzungsverhältnis vom Leitkörper 8 zum Leitkörper 7 kann dadurch in der Größenordnung von 47 : 1 liegen, so daß der Leitkörper 7 z.B. nur höchstens 20 Umdrehungen pro Minute ausführt. Die Drehrichtung der beiden Leitkörper 7, 8 ist gleich sowie gleichgerichtet wie die genannten Antriebsmomente. Die Leitkörper 7, 8 laufen durch die erfindungsgemäße Ausbildung schon bei einem sehr geringen Wasserdurchfluß an, wobei die Drehzahl des Leitkörpers 7 annähernd unabhängig vom Wasserdruck und von der Wasser-Durchflußmenge ist. Der Leitkörper 7 wird nämlich durch Bremswirkung an einer zu hohen Drehzahl gehindert, wobei die Drehzahl des Leitkörpers 8 im Dauerbetrieb proportional zur und nicht schneller als die Fließgeschwindigkeit des Wassers ist. Das durch das Wasser auf den Leitkörper 7 wirkende Antriebsmoment würde somit bei ungebremstem Leitkörper 7 diesem eine wesentlich höhere Drehzahl verleihen.The reduction ratio of the guide body 8 to the guide body 7 can thereby be in the order of 47: 1, so that the guide body 7 is e.g. only a maximum of 20 revolutions per minute. The direction of rotation of the two guide body 7, 8 is the same and rectified as the aforementioned drive torques. The guide body 7, 8 run through the inventive design even at a very low water flow, the speed of the guide body 7 is approximately independent of the water pressure and the water flow rate. The guide body 7 is in fact prevented by braking at too high a speed, wherein the speed of the guide body 8 in continuous operation is proportional to and not faster than the flow rate of the water. The force acting on the guide body 7 by the drive torque would thus give this with a non-braked guide 7 this a much higher speed.

Zur günstigen Teilung des Wassers in einzelne, um die Achse 10 verteilte, etwa gleiche Wasserstrahlen kann die Bodenfläche 41 der Leitfläche 14 den genannten Steigungsverlauf bis zum Austritt 27 haben und spitzwinklig z.B. unter einem Winkel von höchstens 75° und mindestens 45°, insbesondere etwa 60°, so flankiert sein, daß die Flanken 42 im Querschnitt annähernd symmetrisch zu einer Mittelebene durch die Bodenfläche 41 gehen. Die voneinander abgekehrten Flanken 42 zweier benachbarter Leitflächen 14 gehen jeweils über einen Scheitel bzw. Kamm 43 der zugehörigen Schaufel 15 spitzwinklig ineinander über, da diese die Flanken 42 bildet und die nutförmigen Leitflächen 14 voneinander trennt. Die Flanken 42 können erst in einem Axialabstand vom Eintrittsende der Leitflächen 14 beginnen, wobei dieser Abstand größer als der Radius bzw. Durchmesser des Außenumfanges des Mantels 24 im Bereich dieses Eintrittsendes ist und dieser Außenumfang zur Bildung eines zunächst geschlossenen Hüllstromes in der beschriebenen Weise spitzwinklig bzw. progressiv konisch erweitert ist. Die jeweilige Leitnut 14 ist im Querschnitt zur offenen Nutseite wenigstens auf einem Teil ihrer Höhe und insbesondere bis zur ofenen Nutseite erweitert, wobei die Nut- bzw. Schaufelhöhe am Eintrittsende bei Null liegt und in Strömungsrichtung stetig bis progressiv zunimmt. Die Flanken 42 bzw. der jeweilige Kamm 43 steigen dann von einer Nullhöhe oder geringsten Höhe gegenüber dem Außenumfang des Mantels 24 bzw. der Bodenfläche 41 in der Höhe dadurch an, daß der Kamm 43 unter einem größeren Winkel bzw. mit stärkerer Krümmung konkav oder geradlinig ansteigt und in der Austritts-Hüllfläche etwa radial zur Achse 10 gerichtet ist. Die Axialerstrekkung bzw. Höhe der Schaufel 15 kann dann im Bereich des Austrittes 27 kleiner als der Umfangsabstand des Kämme 43 benachbarter Schaufeln 15 in diesem Bereich sein. In Radialansichtbzw. im Querschnitt quer zur Durchflußrichtung sind die Schaufeln 15 spitzwinklig dreieckförmig, wobei ihre Kämme 43 scharfkantig und/oderabgerundet bzw. abgeflachtsein können. Die lichte Breite der Leitfläche 14 nimmt in Strömungsrichtung konstant zu.For the favorable division of the water into individual, approximately equal water jets distributed around the axis 10, the bottom surface 41 of the guide surface 14 can have the aforementioned gradient as far as the exit 27 and at an acute angle, e.g. be flanked at an angle of at most 75 ° and at least 45 °, in particular about 60 °, that the flanks 42 in cross-section approximately symmetrically to a median plane through the bottom surface 41 go. The mutually remote flanks 42 of two adjacent guide surfaces 14 merge into each other via an apex or comb 43 of the associated blade 15 at an acute angle, since this forms the flanks 42 and the groove-shaped guide surfaces 14 separates from each other. The flanks 42 can only begin at an axial distance from the inlet end of the guide surfaces 14, wherein this distance is greater than the radius or diameter of the outer circumference of the jacket 24 in the region of this inlet end and this outer circumference to form an initially closed enveloping current in the manner described acute angle or is progressively conically flared. The respective guide groove 14 is widened in cross-section to the open groove side at least on a part of its height and in particular to the oven groove side, wherein the groove or blade height is zero at the inlet end and steadily increases progressively in the flow direction. The flanks 42 and the respective comb 43 then rise from a zero height or lowest height relative to the outer circumference of the jacket 24 or the bottom surface 41 in height by the fact that the comb 43 at a larger angle or with a greater curvature concave or rectilinear rises and is directed in the exit envelope surface approximately radially to the axis 10. The axial extent or height of the blade 15 can then be smaller than the circumferential distance of the comb 43 of adjacent blades 15 in this region in the region of the outlet 27. In Radialansichtbzw. in cross-section transverse to the flow direction, the blades 15 are triangular at an acute angle, their combs 43 may be sharp-edged and / or rounded or flattened. The clear width of the guide surface 14 increases constantly in the flow direction.

Die Stellvorrichtung 5 oder andere Mittel zur Regulierung des Wasserdurchflusses weist acht in einer Reihe benachbart um eine Achse 10 angeordnete Durchbrüche bzw. Steueröffnungen 44 bis 51 auf, deren Aus- und/oder Eintritte in einer gemeinsamen Ebene liegen und Abstände voneinander haben, welche wesentlich kleiner als die zugehörige Erstreckung der jeweiligen Steueröffnung ist. Die Steueröffnungen bzw. ihre Einoder Auslaßöffnungen nehmen entlang der Reihe im Querschnitt von einer größten Öffnung 44 stufenweise annähernd gleichmäßig zu einer kleinsten Öffnung 51 ab und sind gleichmäßig um die Achse 10 verteilt. Ihre an einer Längsseite der Reihe liegenden Begrenzungen fluchten miteinander, da sie gleiche Radialabstände von der Achse 10 haben, während die davon abgekehrten Begrenzungen abgestuft abnehmende Abstände von der inneren Begrenzung haben und beide Begrenzungen um die Achse 10 gekrümmt sind. Die zueinander benachbarten bzw. einander gegenüberliegenden Seitenbegrenzungen der Öffnungen sind durchgehend annähernd geradlinig, divergieren zu den abgestuften Begrenzungen gleich spitzwinklig und haben entsprechend abgestufte Längen, wobei benachbarte Seitenbegrenzungen benachbarter Öffnungen parallel zueinander und mit dem geringen Abstand voneinander liegen.The adjusting device 5 or other means for regulating the water flow has eight in a row adjacent to an axis 10 arranged openings or control openings 44 to 51, the outlets and / or entries are in a common plane and have distances from each other, which is much smaller as the corresponding extension of the respective Control opening is. The control openings or their inlet or outlet openings along the row in cross-section from a largest opening 44 gradually approximately uniformly to a smallest opening 51 from and are evenly distributed around the axis 10. Their boundaries lying on one longitudinal side of the row are in alignment with each other since they have equal radial distances from the axis 10, while the boundaries facing away therefrom have decreasing distances from the inner boundary and both boundaries are curved about the axis 10. The mutually adjacent or opposite side boundaries of the openings are continuously approximately rectilinear, diverge at the same acute angle to the stepped boundaries and have correspondingly stepped lengths, wherein adjacent side boundaries of adjacent openings parallel to each other and with the small distance from each other.

Zur Änderung des Durchlaßquerschnittes annähernd jeder der genannten Öffnungen zwischen völliger Öffnungsweite und vollständigem Öffnungsverschluß ist ein durchgehend scheiben- bzw. plattenförmiges Steuerglied 52 vorgesehen, welches diejeweilige Steueröffnung an der Ein- und/oder Auslaßöffnung entsprechend abdeckt oder freigibt. Die durchgehend ebene Steuerfläche 53 ist hier nur an den Einlaßseiten der Steueröffnungen vorgesehen und gleitet im wesentlichen durckdicht abschließend an Gegenflächen, welche zwischen den Steueröffnungen sowie beiderseits unmittelbar benachbart zu den Längsseiten der Öffnungsreihe liegen. Das Steuerglied 52 weist in der anhand der Steueröffnungen erläuterten Konfiguration abgestufte Steuerabschnitte 54 bis 60 auf, welche entlang einer entsprechenden Reihe von einem größten Steuerabschnitt 54 zu einem kleinsten Steuerabschnitt 60 abgestuft abnehmen, jedoch an der abgestuften, äußeren Längs- bzw. Umfangsseite jeweils um ein etwa gleiches Maß gegenüber der Umfangsseite der zugehörigen Steueröffnung nach innen zurückversetzt sind. Der kleinsten Steueröffnung 51 braucht daher kein kleinster Steuerabschnitt zugeordnet sein.To change the passage cross-section of each of the said openings between the total opening width and complete opening closure a continuous disk or plate-shaped control member 52 is provided, which covers the respective control opening at the inlet and / or outlet accordingly or releases. The continuous flat control surface 53 is provided here only at the inlet sides of the control openings and slides substantially durckdicht finally to mating surfaces, which lie between the control openings and both sides immediately adjacent to the longitudinal sides of the row of openings. The control member 52 has, in the configuration explained with reference to the control openings, stepped control portions 54 to 60 decreasing along a corresponding row from a largest control portion 54 to a minute control portion 60, but at the stepped outer peripheral side respectively approximately the same amount with respect to the peripheral side of the associated control port are set back inwards. The smallest control opening 51 therefore does not need to be assigned a smallest control section.

Jeder Steuerabschnitt ist etwa um die Breite des Abstandes zwischen benachbarten Steueröffnungen gegenüber der Breite einer Steueröffnung größer, am Innenumfang sind alle Steuerabschnitte gemeinsam durchgehend um die Achse 10 kreisförmig bzw. konkav begrenzt und die radial äußeren Begrenzungen der Steuerabschnitte sind konkav um die Achse 10 gekrümmt, sowie zum jeweils benachbarten Steuerabschnitt abrupt etwa rechtwinklig abgestuft. Die Steueröffnungen 44 bis 51 durchsetzen eine Stirnwand, deren an der Steuerfläche 53 gleitende Seite wie diese Steuerfläche rechtwinklig zur Achse 10 liegt und die, festverbunden mit einem Mantel 61, ein Stellglied bildet. Die Stirnwand 62 liegt mit geringerem Abstand vom oberen als vom unteren Ende des einteilig mit ihr ausgebildeten Mantels 61, welcher ein die Steuerflächen vollständig umschließendes Gehäuse bildet, wobei das Steuerglied 52 an der Unterseite der Steuerwand 62 liegt. Der Außenumfang des Mantels 61 bildet die Handhabe 6, welche beim Austragbetrieb frei zwischen den Einheiten 2, 3 und der Einheit 4 andererseits liegt, jedoch gegenüber diesen kleinere Außenweite hat.Each control section is larger by about the width of the distance between adjacent control openings with respect to the width of a control opening, on the inner circumference all control sections are jointly continuous around the axis 10 circularly or concavely bounded and the radially outer boundaries of the control sections are concavely curved about the axis 10, and abruptly stepped approximately at right angles to the respective adjacent control section. The control openings 44 to 51 pass through an end wall whose sliding on the control surface 53 side as this control surface is perpendicular to the axis 10 and, fixedly connected to a jacket 61, an actuator forms. The end wall 62 is located at a smaller distance from the upper than the lower end of the integrally formed therewith jacket 61, which forms a control surfaces completely enclosing housing, wherein the control member 52 is located on the underside of the control wall 62. The outer circumference of the jacket 61 forms the handle 6, which in the discharge operation is free between the units 2, 3 and the unit 4 on the other hand, but with respect to this smaller outer width.

Die Stellvorrichtung 5 kann durch Drehen der Handhabe 6 stufenlos verstellt werden, wobei jedoch zweckmäßig mehrere, insbesondere eine der Anzahl der Steueröffnungen 44 bis 51 entsprechende Anzahl von bevorzugten Stellungen durch federnde Rastung fühlbar bestimmt und festgelegt und lediglich durch Aufbringen einer entsprechend kräftigen Betätigung der Handhabe 6 zu überwinden sind. Bei einer bevorzugten Stellung gemäß Fig. 3 sind alle Steueröffnungen wenigstens in ihrem radial äußeren Bereich freigegeben, wobei bis auf die kleinste Steueröffnung 51 von allen übrigen Steueröffnungen der radial innere Bereich verschlossen und somit nur der radial äußere Bereich als geöffneter Durchlaßquerschnitt 64 freigegeben ist; die kleinste Öffnung 51 kann vollständig freigegeben sein. Die Summe der Durchlaßquerschnitte 64 entspricht dann etwa dem weitest freizugebenden bzw. gesamten Durchlaßquerschnitt der größten Steueröffnung 44, wobei die Breite jedes Durchlaßquerschnittes 64 in Umfangsrichtung bis zu einer oder beiden Seitenbegrenzungen der zugehörigen Steueröffnung durchgehend konstant bzw. bei allen Steueröffnungen etwa gleich ist. Somit tritt durch die etwa gleichen Durchlaßquerschnitte 64 über eine Bogenwinkel von 360° um die Achse 10 annähernd gleichmäßig Wasser aus.The adjusting device 5 can be adjusted continuously by turning the handle 6, but expediently several, especially one of the number of control openings 44 to 51 corresponding number of preferred positions by resilient detent tactile determined and determined and only by applying a correspondingly vigorous operation of the handle. 6 to be overcome. In a preferred position according to FIG. 3, all the control openings are released at least in their radially outer area, wherein, except for the smallest control opening 51, the radially inner area is closed by all other control openings and thus only the radially outer area is released as an opened passage cross section 64; the smallest opening 51 can be fully released. The sum of the passage cross-sections 64 then corresponds approximately to the widest to be released or total passage cross section of the largest control port 44, wherein the width of each passage cross-section 64 in the circumferential direction to one or both side boundaries of the associated control port is constant or constant at all control ports approximately equal. Thus, by approximately the same passage cross-sections 64 over an arc angle of 360 ° about the axis 10 approximately uniformly from water.

Bei der Einstellung nach Fig. 4 beträgt dieser Bogenwinkel nur 135°, weil die fünf kleinsten Steueröffnungen 47 bis 51 vollständig verschlossen, die beiden größten Steueröffnungen 44, 45 radial innen nur teilweise verschlossen und die drittgrößte Steueröffnung 46 auf voller Weite freigegeben ist. Jede beliebige Steueröffnung kann somit auf voller Weite freigegeben oder auf einem beliebig großen, radial innenliegenden, Abschnitt verschlossen werden. Der Durchlaßquerschnitt 65 jeder freigegebenen Steueröffnung 44 bis 46 ist somit größer als der entsprechende Durchlaßquerschnitt 64 gemäß Fig. 3, jedoch ist die Summe aller Durchlaßquerschnitte 65 gemäß Fig. 4 wiederum etwa gleich der Summe aller Durchlaßquerschnitte 64 gemäß Fig. 3, was für jede der bevorzugten bzw. gerasteten Stellungen gilt. Mit Abnahme des Bogenwinkels bzw. der Anzahl oder Reihenausdehnung der Durchlaßquerschnitte nimmt somit der einzelne Durchlaßquerschnitt 65 zu. Die größte Steueröffnung 44 kann bis zum Innenumfang des Mantels 61 reichen, während die Radialerstreckung der kleinsten Öffnung 51 etwa der Quer- bzw. Radialerstreckung eines Durchlaßquerschnittes 64 entsprechen kann.In the setting of Fig. 4, this arc angle is only 135 °, because the five smallest control ports 47 to 51 completely closed, the two largest control ports 44, 45 radially inside only partially closed and the third largest control port 46 is released to full width. Any control opening can thus be released to full width or closed on an arbitrarily large, radially inner, section. The passage cross section 65 of each released control port 44 to 46 is thus greater than the corresponding passage cross section 64 of FIG. 3, but the sum of all passage cross sections 65 of FIG. 4 is again approximately equal to the sum of all passage cross sections 64 of FIG. 3, which is for each of preferred or latched positions applies. With a decrease in the arc angle or the number or series expansion of the passage cross sections, the individual passage cross section 65 thus increases. The largest control opening 44 may extend to the inner circumference of the jacket 61, while the radial extent of the smallest opening 51 may correspond approximately to the transverse or radial extent of a passage cross-section 64.

In Strömungsrichtung an die Auslaßseiten schließt eine für alle Steueröffnungen 44 bis 51 gemeinsame, zentrale Richtöffnung 63 der Richtdüse 13 an, welche ununterbrochen durchgehend ringförmig, am Außenumfang von einem axial unmittelbar an die Steueröffnungen anschließenden Abschnitt der Stirnwand 62 sowie am Innenumfang von einem feststehenden Dorn, z.B. der einteilig mit dem Grundkörper 2 fest verbundenen Konsole für die Achseinheit 17, 18 gebildet ist. Der Außenumfang der Richtdüse 13 hat etwas kleineren Radialabstand von der Achse 10 als die inneren Begrenzungen der Steueröffnungen, welche über entsprechende Querkanäle, z.B. Anfasungen, radial nach innen gerichtet gesondert mit der Richtöffnung 63 leitungsverbunden sind. Das durch die Durchflußquerschnitte 64, 65 strömende Wasser wird durch den vom Steuerglied 52 abgedeckten Bereich der zugehörigen Steueröffnung radial nach innen geführt und dann quer bzw. axial in die Richtdüse 13 umgelenkt, aus welcher das Wasser nur auf dem jeweils eingestellten Bogenwinkel in die Einlaßseite des Leitkörpers 7 bzw. die Leitflächen 14 eintritt. Der Außenumfang des Mantels 24 bzw. der Leitflächen 14 entspricht etwa dem Innenumfang bzw. der Hüllfläche der radial inneren Begrenzung der Richtdüse 13, welche auch durch einzelne, über den Umfangverteilte Kanäle gebildet sein könnte. Das Steuerglied 52 ist mit einer Nabe axial und/oder radial festsitzend auf dem Außenumfang der Konsole angeordnet und gegenüber dieser durch eine Ringdichtung 66 abgedichtet, so daß es zur Demontage wie die Einheiten 7, 8, 9, 17, 18, 31, 32, 33, 61, 62 nach oben zerstörungsfrei abgezogen werden kann.In the flow direction to the outlet sides includes a common for all control ports 44 to 51, central directional opening 63 of the directional nozzle 13, which continuously uninterrupted annular, on Outer circumference of an axially immediately adjacent to the control openings portion of the end wall 62 and the inner circumference of a fixed mandrel, for example, the integral with the main body 2 firmly connected console for the axle unit 17, 18 is formed. The outer circumference of the directional nozzle 13 has slightly smaller radial distance from the axis 10 than the inner boundaries of the control openings, which are connected via corresponding transverse channels, eg chamfers, directed radially inwardly separately connected to the directional opening 63. The flowing through the flow areas 64, 65 water is guided by the covered by the control member 52 portion of the associated control port radially inward and then deflected transversely or axially into the directional nozzle 13, from which the water only at the set arc angle in the inlet side of the Guide body 7 and the guide surfaces 14 occurs. The outer circumference of the jacket 24 or the guide surfaces 14 corresponds approximately to the inner circumference or the envelope surface of the radially inner boundary of the directional nozzle 13, which could also be formed by individual channels distributed over the circumference. The control member 52 is arranged with a hub axially and / or radially fixed on the outer circumference of the console and sealed against this by a ring seal 66 so that it for disassembly as the units 7, 8, 9, 17, 18, 31, 32, 33, 61, 62 can be pulled up nondestructively.

Die Einheiten 6 bzw. 61, 62 sind mit einem Lager 67 parallel zur Stellrichtung entgegengesetzt bewegbar bzw. drehbar am oberen Ende des Grundkörpers 2 über mehr als eine Volldrehung drehbar gelagert, wobei der Außenumfang der Handhabe 6 eine annähernd kontinuierliche Fortsetzung des, gleiche Außenweite aufweisenden, Außenumfanges des Grundkörpers 2 bildet und dieser mit der demgegenüber wesentlich reduzierten Konsole nach oben über das obere Ende seines freiliegenden Außenmantels in die Handhabe 6 vorsteht, in welche von oben das untere, verjüngte Ende des Leitkörpers 7 hineinragt. So bildet das obere Ende des Mantels 61 im Austragbetrieb eine äußere Abschirmung der Wasserführung im Leitkörper 7, deren Axialabstand von den Kämmen 43 wesentlich kleiner als die Hälfte, ein Drittel oder ein Viertel ihrer Innenweite ist.The units 6 and 61, 62 are rotatably mounted with a bearing 67 parallel to the actuating direction opposite or rotatably mounted on the upper end of the body 2 for more than one full turn, wherein the outer periphery of the handle 6 has an approximately continuous continuation of the same outer width , Outer circumference of the base body 2 forms and this projecting with the contrast substantially reduced console upwards over the upper end of its exposed outer shell into the handle 6, in which from above the lower, tapered end of the guide member 7 protrudes. Thus, the upper end of the jacket 61 in the discharge operation forms an outer shield of the water guide in the guide body 7, the axial distance from the combs 43 is substantially smaller than half, one-third or one-fourth of its inner width.

Das Gleitlager 67 schließt eine Abdichtung sowie eine Schnappverbindung 68 des Stellkörpers 6 gegenüber dem oberen Ende des Grundkörpers 2 ein, welches hülsenförmig in das untere Ende des Mantels 61 eingreift, am Außenumfang ein ringförmiges Schnappglied bildet und den Körper 6 gegen axiales Abziehen sowie im wesentlichen axial- und/oder radialspielrei sichert. Der Körper 6 braucht zur Montage lediglich axial auf das zugehörige Ende des Grundkörpers 2 aufgesteckt und axial angepreßt zu werden, damit die in der Achse 10 liegende Schnappverbindung zunächst federnd freigibt und dann von selbst formschlüssige einrastet, wobei dann die Steuerfläche 53 des vormontierten Steuergliedes 52 an der Stirnwand 62 funktionsgerecht und unter der Wirkung der Dichtung 66 vorgespannt federnd anliegt.The sliding bearing 67 includes a seal and a snap connection 68 of the actuating body 6 relative to the upper end of the base body 2, which engages sleeve-shaped in the lower end of the shell 61, forms an annular snap member on the outer periphery and the body 6 against axial withdrawal and substantially axially - and / or radial playrei secures. The body 6 only needs to be mounted axially mounted on the associated end of the base body 2 and axially pressed so that the snap-in connection in the axis 10 initially releases resiliently and then locks by itself form-fitting, in which case the control surface 53 of the preassembled control member 52 at the end wall 62 is functionally correct and resiliently biased under the action of the seal 66.

Wie insbesondere die Fig. 2, 5 und 6 zeigen, können die Flanken 42 im Querschnitt von der ebenen Form abweichen oder quer zur Durchflußrichtung winklig abgestufte Flankenabschnitte 69, 70 aufweisen und der Boden 41 kann von der konkav gekrümmten bzw. halbkreisförmigen Form abweichen, z.B. im Anschluß an die quer bzw. rechtwinklig zu ihm liegenden Flankenabschnitte 69 eben sein. Diese, parallel einander gegenüberstehenden Flankenabschnitte 69 sind wesentlich niedriger als die anschließenden Flankenabschnitte 70, welche unter einem Winkel von etwa 60° gleichförmig bis zu den Kämmen 43 divergieren, mindestens fünf- und höchstens fünfzehnfach höher als die Flankenabschnitte 69 sein können und jeweils unter Bildung einer vorspringenden Kante in den zugehörigen Flankenabschnitt 69 übergehen. Die Flankenabschnitte 69 bilden die Seitenflanken einer etwa rechtwinkligen, bis zum Austritt 27 etwa konstant breiten Bodennut 71, welche den schmalsten Bereich des Durchflußquerschnittes der gesamten, bis zu den Kämmen 43 reichenden Nuthöhe bildet und ihrerseits eine gegenüber ihrer Nuthöhe geringfügig kleinere Nutbreite haben kann. Das jeweilige dieser Maße beträgt mindestens einen Millimeter und höchstens zwei bis drei Millimeter. Es hat sich gezeigt, daß durch diese Ausbildungen der Wirkungsgrad der Turbinen 7, 8 bzw. die Wurfweite des Wassers vergrößert sowie verbessert werden können, insbesondere durch die Kombination eines im Querschnitt verengten Bereiches 71 und eines demgegenüber, ggf. abgestuft, erweiterten bzw. sich erweiternden Abschnittes 70.Referring particularly to Figs. 2, 5 and 6, the flanks 42 may deviate in cross-section from the planar shape or have flared edge portions 69, 70 transverse to the flow direction and the bottom 41 may deviate from the concave or semicircular shape, e.g. be flat following the transversely or perpendicular to him flank sections 69. These mutually parallel flank portions 69 are substantially lower than the subsequent flank portions 70, which diverge at an angle of about 60 ° uniformly to the crests 43, at least five and at most fifteen times higher than the flank portions 69 may be and each to form a go over the projecting edge in the associated edge portion 69. The flank sections 69 form the side flanks of an approximately rectangular ground groove 71 which is approximately constant up to the outlet 27, which forms the narrowest region of the flow cross section of the entire groove height reaching up to the combs 43 and can in turn have a slightly smaller groove width compared to its groove height. The respective dimensions are at least one millimeter and at most two to three millimeters. It has been shown that the efficiency of the turbines 7, 8 or the throw of the water can be increased and improved by these embodiments, in particular by the combination of a narrowed in cross-section 71 and a contrast, possibly graduated, extended or expanding section 70.

Die Regner gemäß den Fig. 1 und 7 sind als Versenkregner ausgebildet, bei welchen der Grundkörper 2 mit dem Kopf 4 nach oben in die Arbeitsstellung gemäß Fig. 1 anschlagbegrenzt ausfahrbar und nach unten in eine Versenkstellung in den Träger 3 so einfahrbar ist, daß der Kopf 4 bzw. die Stirnwand 26 mit ihrem radial über den Fluidausgang 12 und die Schaufeln 16 vorstehenden Ringrand einen abdeckenden Verschluß für das obere Ende des Trägers 3 bildet. Dieses obere Ende ist durch einen hülsenförmigen Endabschluß 72 gebildet, welcher über eine in der Achse 10 liegende Gewindeverbindung lagestarr am oberen Ende des Trägers 3 befestigt ist, mit einer Querwand 74 eine am Außenumfang des Grundkörpers 2 gleitende Ringdichtung 73 gegen das obere Ende des Trägers 3 spannt und einen gegenüber dem Außenumfang des Trägers 3 geringfügig erweiterten Außenumfang hat. Gegen die Querwand 74 stützt sich auch eine den Grundkörper2 umgebende, innerhalb des Trägers 3 liegende Rückholfeder 75 ab, welche die Einheiten 2, 4, 5 gemeinsam zurück nach unten in den Träger 3 holt, wenn der diese Einheiten in die Ausfahrstellung überführende und in der Ausfahrstellung haltende Wasserdruck entsprechend reduziert wird, wobei das dem Kopf 4 zugeführte Wasser am Einlaßende des Trägers 3 innerhalb eines entsprechenden Zylinderraumes auf einen Kolben am unteren Ende des Grundkörpers 2 wirkt. Im eingefahren Zustand sind die genannten wasserbeaufschlagten Flächen der Einheiten 4, 5 sowie die Handhabe 6 durch den Träger 3 bzw. das Gehäuse 72 nach außen vollständig abgeschlossen, wobei die Einheiten 61, 67, 68 in den Grundkörper 3 hineinragen und die Dichtung 73 am Außenumfang des Mantels 61 mit Abstand zwischen dessen Enden dichtend anliegt.The sprinklers of FIGS. 1 and 7 are designed as pop-up sprinkler, in which the base body 2 with the head 4 upwards in the working position shown in FIG. 1 stop-limited extendable and down into a lowered position in the carrier 3 is retracted so that the Head 4 and the end wall 26 forms a covering closure for the upper end of the carrier 3 with its radially above the fluid outlet 12 and the blades 16 projecting annular edge. This upper end is formed by a sleeve-shaped end closure 72, which is fastened fixedly in position on the upper end of the carrier 3 via a threaded connection 10 located in the axis 10, with a transverse wall 74 on the outer periphery of the main body 2 sliding ring seal 73 against the upper end of the carrier. 3 spans and has a relation to the outer periphery of the carrier 3 slightly enlarged outer circumference. Against the transverse wall 74 is also a Grundkörper2 surrounding, lying within the carrier 3 return spring 75, which brings the units 2, 4, 5 together back down into the carrier 3, when these units in the extended position and in the Retracting water pressure is reduced accordingly, the head 4 supplied water acts at the inlet end of the carrier 3 within a corresponding cylinder space on a piston at the lower end of the base body 2. In the retracted state said water-exposed surfaces of the units 4, 5 and the handle 6 are completely closed by the carrier 3 and the housing 72 to the outside, wherein the units 61, 67, 68 protrude into the base body 3 and the seal 73 on the outer periphery of the jacket 61 with a distance between the ends sealingly.

Gemäß Fig. 7 ist das erste Getriebeglied 31 statt mit einem gemeinsamen mit zwei gesonderten Eingriffs- bzw. Zahnkränzen für die zweiten und dritten Getriebeglieder 35, 36 versehen, wodurch das Übersetzungsverhältnis beliebig vergrößert oder verkleinert werden kann. Die beiden Zahnkränze 34a, 34b haben durch gegenseitige Abstufung unterschiedliche Durchmesser bzw. Zähnezahlen, wobei hier der Zahnkranz 34a, an welchem der Zahnkranz 35 exzentrisch umlaufend abwälzt, einen kleineren Durchmesser als der Zahnkranz 34b für den entsprechend abwälzenden Zahnkranz 36 des Getriebegliedes 33 hat.According to Fig. 7, the first gear member 31 is provided instead of a common with two separate engagement or sprockets for the second and third gear members 35, 36, whereby the gear ratio can be arbitrarily increased or decreased. The two sprockets 34a, 34b have by mutual gradation different diameters or numbers of teeth, in which case the sprocket 34a, on which the sprocket 35 eccentrically revolving, a smaller diameter than the sprocket 34b for the corresponding rolling sprocket 36 of the gear member 33 has.

Wird dem Regner in der Ruhe- bzw. Ausgangsstellung gemäß Fig. 7 vom Fluideingang her Wasser unter Druck zugeführt, so hebt dieses Wasser die Einheiten 2 und 4 bis 6 in die Stellung gemäß Fig. 1 aus und strömt gleichzeitig innerhalb des Grundkörperrohres 2 zur Stellvorrichtung 6 sowie durch diese hindurch gegen die Leitkörper 14, 16, so daß spätestens mit Erreichen der ausgefahrenen Stellung beide Leitkörper 7, 8 durch das strömende Wasser dem gleichgerichteten Antriebsmoment um die Achse 10 unterworfen sind und mit wesentlich unterschiedlicher Geschwindigkeit beginnen in gleicher Richtung zu drehen. Das Wasser wird dabei auf dem eingestellten Bogenwinkel sofort mit großer Wurfweite gebündelt ausgetragen und fächert mit zunehmender Wurfentfernung vom Regnerkopf 4 weiter auf, so daß benachbarte Wasserstrahlen einander vor Erreichen des Bodens überdecken, jedoch durch die Rotation des Leitkörpers 7 in Draufsicht nicht oder nur einer unwesentlichen Krümmung bzw. Auffächerung unterworfen werden. Im wesentlichen alle der genannten Bauteile können aus Kunststoff bestehen bzw. als Spritzgußteile ausgebildet sein.If water is supplied under pressure to the sprinkler in the rest or initial position according to FIG. 7 from the fluid inlet, this water lifts the units 2 and 4 to 6 into the position according to FIG. 1 and simultaneously flows within the main body tube 2 to the adjusting device 6 and therethrough against the baffle 14, 16, so that at the latest when reaching the extended position both baffles 7, 8 are subjected to the rectified drive torque about the axis 10 by the flowing water and start at a significantly different speed in the same direction. The water is discharged at the set arc angle immediately bundled with great throw and fanning with increasing throw distance from the sprinkler head 4 on, so that adjacent water jets cover each other before reaching the bottom, but not by the rotation of the guide body 7 in plan view or only a negligible Curvature or fanning be subjected. Essentially all of the components mentioned may consist of plastic or be formed as injection molded parts.
