Abstract
Description
Die Erfindung betrifft einen Strahlregler, gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a jet regulator, according to the preamble of claim 1.
Es ist bereits bekannt, am Wasserauslauf einer sanitären Auslaufarmatur einen Strahlregler zu montieren, der einen homogenen, nicht-spritzenden Wasserstrahl formen soll. Solche, Strahlregler werden meist in ein Auslaufmundstück eingesetzt, das am Wasserauslauf der sanitären Auslaufarmatur lösbar anschraubbar ist.It is already known to mount at the water outlet of a sanitary outlet fitting a jet regulator, which is to form a homogeneous, non-splashing water jet. Such, jet regulators are usually used in an outlet nozzle, which is detachably screwed on the water outlet of the sanitary outlet fitting.
Da die Ausgestaltung des Auslaufmundstücks in der Oberflächenausführung der sanitären Auslaufarmatur mit einem erheblichen Aufwand verbunden sein kann, und da der zwischen Auslaufmundstück und Auslaufarmatur verbleibende Spalt häufig als störend empfunden wird, hat man bereits Strahlregler der eingangs erwähnten Art geschaffen, die von der Auslaufstirnseite aus in den Wasserauslauf einer sanitären Auslaufarmatur einsetzbar sind, ohne dass zum Festlegen des Strahlreglers ein zusätzliches Auslaufmundstück erforderlich wäre.Since the design of the outlet mouthpiece in the surface finish of the sanitary outlet fitting can be associated with considerable effort, and since the gap remaining between outlet nozzle and outlet fitting is often bothersome, one has already created jet regulator of the type mentioned, from the outlet end face in the water outlet of a sanitary outlet fitting can be used without an additional outlet nozzle would be required to set the jet regulator.

Mit dem stetig wachsenden ästhetischen Anspruch an sanitäre Auslaufarmaturen wachsen auch die an die erforderlichen Strahlregler gestellten Anforderungen. Es besteht daher die Aufgabe, einen Strahlregler der eingangs erwähnten Art zu schaffen, bei dem der die sanitäre Auslaufarmatur verlassende Wasserstrahl die Kontur des Wasserauslaufs oder des Auslaufrohres geometrisch fortführt und somit für ein homogenes Gesamtbild von Auslauf und Wasserstrahl als Einheit sorgt. Die Aufgabe besteht also darin, einen bevorzugt belüfteten Wasserstrahl so zu gestalten, dass er nahezu die freie wasserführende Querschnittsfläche des Wasserauslaufs aufweist und somit die Querschnittsgeometrie der Innenkontur der sanitären Auslaufarmatur - senkrecht zur Fließrichtung - , die sich nur durch die Wandstärke des Auslaufteiles von der sichtbaren Außenkontur unterscheidet, übernimmt.With the steadily growing aesthetic demand for sanitary outlet fittings, the requirements placed on the required jet regulators are also growing. It is therefore an object to provide a jet regulator of the type mentioned, in which the sanitary outlet fitting water jet leaving the contour of the water outlet or the outlet pipe continues geometrically and thus provides a homogeneous overall picture of spout and water jet as a unit. The task is therefore to make a preferably aerated water jet so that it has almost the free water-bearing cross-sectional area of the water outlet and thus the cross-sectional geometry of the inner contour of the sanitary outlet fitting - perpendicular to the flow direction - which only by the wall thickness of the outlet part of the visible Outline different, takes over.
Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere darin, dass ein zum Belüften des Wasserstrahls erforderlicher Belüftungskanal auf einen der Sichtseite der Auslaufarmatur abgewandt anzuordnen Teilumfang zwischen Strahlregleraußenumfang und Armatureninnenumfang begrenzt ist.The inventive solution to this problem is in the jet regulator of the type mentioned in particular that a venting of the water jet required ventilation channel facing away from the visible side of the outlet fitting to arrange part of the circumference between the jet outer circumference and the inner circumference of the fitting is limited.
Bei dem erfindungsgemäßen Strahlregler erstreckt sich der zum Belüften des Wasserstrahls erforderliche Belüftungskanal nicht - wie üblich - über den gesamten Umfang zwischen Strahlregleraußenumfang und Armatureninnenumfang, - vielmehr ist dieser Belüftungskanal auf einen der Sichtseite der Auslaufarmatur abgewandt angeordneten Teilumfang begrenzt. Da die zur Erzeugung eines belüfteten Strahles erforderliche Luft nicht allseitig, sondern nur an einem der Sichtseite der Auslaufarmatur abgewandten Teilumfang angesaugt wird, wird die Ausnutzung der zur Verfügung stehenden Flächen erhöht, was insbesondere bei einer in ihrem lichten Armatureninnenumfang breiten aber flachen Auslaufarmatur von besonderer technischer und ästhetischer Bedeutung ist.In the jet regulator according to the invention, the ventilation duct required for aerating the water jet does not extend over the entire circumference between the outer edge of the aerator and the inner circumference of the instrument, as is customary; rather, this ventilation duct is limited to a partial circumference facing away from the visible side of the outlet fitting. Since the required for generating a ventilated jet air is not sucked on all sides, but only on one of the visible side of the outlet fitting part circumference, the utilization of the available areas is increased, which in particular at a wide inside their clear tap inside but flat outlet fitting of special technical and aesthetic meaning.
Zur Lösung der oben genannten Aufgabenstellung sieht ein weiterer Vorschlag von eigener schutzwürdiger Bedeutung vor, dass das Längenmaß mindestens einer Dimension des Wasserstrahles am Austritt senkrecht zu seiner Fließrichtung gleich dem Auslaufinnenmaß abzüglich der zweifachen Gehäusewandstärke des Strahlreglers ist.To solve the abovementioned task, another proposal with its own worthy of protection provides that the length dimension of at least one dimension of the water jet at the exit perpendicular to its flow direction is equal to the outlet internal dimension less twice the housing wall thickness of the jet regulator.
Damit der erfindungsgemäße Strahlregler auch hohen Ansprüchen genügen und bei den verschiedensten Auslaufarmaturen vorteilhaft angesetzt werden kann, sieht ein weiterer Vorschlag von eigener schutzwürdiger Bedeutung vor, dass zum Festlegen oder Fixieren des Strahlreglers im Wasserauslauf zumindest ein Halteelement vorgesehen ist, das eine am Umfang des Armaturengehäuses vorgesehene Durchtrittsöffnung durchsetzt und mit seinem, in das Gehäuseinnere des Armaturengehäuses vorstehenden Endbereich am Strahlregler fixierend angreift.Thus, the jet regulator according to the invention also meet high standards and can be advantageously applied to a variety of outlet fittings, provides a further proposal of own worthy significance that for fixing or fixing the jet regulator in the water outlet at least one holding element is provided, which provided on the circumference of the fitting housing Passage through opening and with his, in the housing interior of the valve body protruding end portion on the jet regulator fixing.
Der erfindungsgemäße Strahlregler kann bei Bedarf von der Auslaufstirnseite aus in den wasserauslauf einer sanitären Auslaufarmatur eingesetzt werden. Um den erfindungsgemäßen Strahlregler dort lösbar festlegen und fixieren zu können, ist zumindest ein Haltelement vorgesehen, das eine am Umfang des Armaturengehäuses vorgesehene Durchtrittsöffnung durchsetzt, wobei das Halteelement mit seinem, in das Gehäuseinnere des Armaturengehäuses vorstehenden Endbereich am Strahlregler fixierend angreift. Da das zumindest eine Halteelement an jedem beliebig geformten Strahlregler angreifen kann, begünstigt der erfindungsgemäße Strahlregler die Gestaltungsfreiheit bei der Gestaltung neuer Auslaufarmaturen, ohne dass Funktionseinbußen hinzunehmen sind. Da der erfindungsgemäße Strahlregler an seinem Gehäuseumfang kein Außengewinde und auch keine Bajonettverbindung benötigt, kann zumindest sichtseitig praktisch der gesamte lichte Querschnitt der Auslaufarmatur mit Ausnahme der Strahlreglergehäusewände wasserführend ausgestaltet werden.If necessary, the jet regulator according to the invention can be inserted from the outlet end face into the water outlet of a sanitary outlet fitting. In order to be able to detachably fix and fix the jet regulator according to the invention there, at least one holding element is provided which passes through a passage opening provided on the circumference of the fitting housing, wherein the holding element with its end region protruding into the housing interior of the fitting housing fixes in a fixing manner on the jet regulator. Since the at least one retaining element can act on any arbitrarily shaped jet regulator, the jet regulator according to the invention favors the freedom of design in the design of new outlet fittings, without having to accept loss of function. Since the jet regulator according to the invention requires no external thread and no bayonet connection at its circumference, virtually the entire clear cross-section of the outlet fitting, with the exception of the jet regulator housing walls, can be made water-conducting at least on the visible side.
Zwar kann das Halteelement den Strahlregler auch fixierend beaufschlagen. Um jedoch den vergleichsweise dünnwandigen Strahlregler nicht unnötig zu verformen, kann es vorteilhaft sein, wenn das Halteelement in eine Befestigungsöffnung am Strahlregler angreift.Although the holding element can act on the jet regulator also fixing. However, in order not to unnecessarily deform the comparatively thin-walled jet regulator, it can be advantageous if the retaining element engages in a fastening opening on the jet regulator.
Das Haltelement kann als Haltesplint ausgestaltet sein, der die Durchtrittsöffnung am Armaturengehäuse sowie eine Befestigungsöffnung am Strahlregler durchsetzt. Eine bevorzugte Ausführungsform gemäß der Erfindung sieht jedoch vor, dass das Halteelement als Halteschraube ausgebildet ist, die in die Durchtrittsöffnung und/oder die Befestigungsöffnung einschraubbar ist.The holding element can be designed as a retaining pin, which passes through the passage opening on the fitting housing and a mounting opening on the jet regulator. However, a preferred embodiment according to the invention provides that the retaining element is designed as a retaining screw which can be screwed into the passage opening and / or the fastening opening.
Besonders vorteilhaft ist es, wenn das Haltelement ein selbstschneidendes Gewinde hat und wenn das Haltelement beim Einschrauben ein Gewinde in die Befestigungsöffnung schneidet. Somit ist es nicht erforderlich, die Gewindegänge in der Durchtrittsöffnung einerseits an die Gewindegänge in der Befestigungsöffnung andererseits anzupassen.It is particularly advantageous if the holding element has a self-tapping thread and if the holding element cuts a thread into the fastening opening when screwing in. Thus, it is not necessary to adapt the threads in the passage opening on the one hand to the threads in the mounting hole on the other.
Das Halteelement tritt am Außenumfang des Armaturengehäuses nicht weiter störend in Erscheinung, wenn das Halteelement als Madenschraube ausgestaltet ist und/oder wenn an dem sichtseitigen Endbereich des Halteelementes eine vorzugsweise als Innensechskant ausgestaltete Werkzeugangriffsfläche vorgesehen ist.The retaining element does not appear disturbing on the outer circumference of the fitting housing when the retaining element is designed as a grub screw and / or if a preferably arranged as a hexagon tool engagement surface is provided on the visible end of the holding element.
Besonders zweckmäßig ist es, wenn die Befestigungsöffnung an ihrem Innenumfang eine aus axial verlaufenden Vorsprüngen und Vertiefungen gebildete Profilierung hat. Während das Haltelement sich in den axialen Vorsprüngen mit geringem Aufwand einschneiden kann, kann das beim Gewindeschneiden verdrängte Material in den Bereich der Vertiefungen verpresst werden, wo es nicht weiter stört.It is particularly expedient if the attachment opening has a profiling formed on its inner circumference from axially extending projections and depressions. While the holding element can cut into the axial projections with little effort, which displaced during tapping Material be pressed into the area of the wells where it does not bother.
Um einen perlend-weichen Wasserstrahl zu formen, ist es vorteilhaft, wenn der Strahlregler als belüfteter Strahlregler ausgestaltet ist und wenn zumindest in einem Teilbereich zwischen Armatureninnenumfang und Strahlregler ein zur Auslaufstirnseite des Wasserauslaufs offener Belüftungskanal vorgesehen ist.In order to form a pearl-soft water jet, it is advantageous if the jet regulator is designed as a ventilated jet regulator and if at least in a partial area between the valve inner circumference and jet regulator is provided for the outlet end side of the water outlet open ventilation channel.
Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass zumindest eine Befestigungsöffnung im Bereich des Belüftungskanals am Strahlreglergehäuse angeordnet ist.In this case, a preferred embodiment according to the invention provides that at least one attachment opening is arranged in the region of the ventilation channel on the jet regulator housing.
Da zum Einsetzen und Fixieren des erfindungsgemäßen Strahlreglers kein Außengewinde am Strahlreglergehäuse erforderlich ist, hat der erfindungsgemäße Strahlregler einen langgestreckten und/oder rechteckigen Außenumfang.Since no external thread on the jet regulator housing is required for insertion and fixing of the jet regulator according to the invention, the jet regulator according to the invention has an elongated and / or rectangular outer periphery.
Ein weiterer erfinderischer Vorschlag von eigener schutzwürdiger Bedeutung sieht vor, dass der eingangs erwähnte Strahlregler ein Strahlreglergehäuse mit einer umfangsseitigen Einschuböffnung hat, dass im Gehäuseinneren des Strahlreglergehäuses zumindest eine quer zur Strahlreglerlängsachse orientierte Einschubführung vorgesehen ist und dass von der Einschuböffnung aus zumindest ein vorzugsweise strahlformendes Einsetzteil in die zumindest eine Einschubführung einschiebbar ist. Bei dem erfindungsgemäßen Strahlregler können die zum Formen des Wasserstrahls zusätzlich benötigten Einsetzteile von einer umfangsseitigen Einschuböffnung aus in das Gehäuseinnere des Strahlreglergehäuses eingeschoben werden. Im Gehäuseinneren des Strahlreglergehäuses ist dazu zumindest eine quer zur Strahlreglerlängsachse orientierte Einschubführung vorgesehen, in die wenigstens ein vorzugsweise strahlformendes Einsetzteil seitlich eingeschoben werden kann.Another inventive proposal of its own worthy of protection provides that the jet regulator mentioned above has a jet regulator housing with a peripheral insertion opening, that at least one insertion guide oriented transversely to the longitudinal axis of the jet regulator housing is provided in the housing interior of the jet regulator housing and that at least one preferably jet-forming insert part from the insertion opening the at least one insertion guide can be inserted. In the jet regulator according to the invention, the additional parts additionally required for shaping the water jet can be inserted from a peripheral insertion opening into the housing interior of the jet regulator housing. In the housing interior of the jet regulator housing is at least one transverse to Provided jet regulator longitudinal axis oriented insertion guide into which at least one preferably jet-forming insert part can be inserted laterally.
Damit der lichte Querschnitt des Wasserauslaufs praktisch vollständig zum Formen des Wasserstrahls genutzt werden kann, ist es vorteilhaft, wenn zumindest ein, in einer Einschubführung vorgesehenes Einsetzteil sich im wesentlichen über den lichten Durchlaufquerschnitt des Strahlreglergehäuses erstreckt.So that the clear cross section of the water outlet can be used almost completely for shaping the water jet, it is advantageous if at least one insertion part provided in an insertion guide extends substantially over the clear flow cross section of the jet regulator housing.
Eine besonders einfache und vorteilhafte Ausführungsform gemäß der Erfindung sieht vor, dass zumindest ein Einsetzteil plattenförmig ausgestaltet ist.A particularly simple and advantageous embodiment according to the invention provides that at least one insert part is designed plate-shaped.
Um die Funktion eines Strahlzerlegers, einer Homogenisiereinrichtung und/oder eines Strömungsgleichrichters auszuüben, kann es vorteilhaft sein, wenn zumindest ein Einsetzteil eine vorzugsweise strahlformende Sieb-, Gitter- oder Netzstruktur hat.In order to perform the function of a jet decomposer, a homogenizer and / or a flow straightener, it may be advantageous if at least one insert has a preferably jet-forming screen, grid or mesh structure.
Damit im erfindungsgemäßen Strahlregler die verschiedenen Funktionen optimiert werden können, kann es vorteilhaft sein, wenn in das Strahlreglergehäuse zumindest zwei Einsetzteile einschiebbar sind, die vorzugsweise unterschiedliche Sieb-, Gitter- und Netzstrukturen haben.So that the various functions can be optimized in the jet regulator according to the invention, it may be advantageous if at least two insert parts can be inserted into the jet regulator housing, which preferably have different screen, grid and net structures.
Um dem eine seitliche Einschuböffnung aufweisenden Strahlreglergehäuse eine ausreichende Stabilität zu geben, kann es vorteilhaft sein, wenn in das Strahlreglergehäuse eine vorzugsweise als Lochplatte ausgestaltete Strahlzerlegeeinrichtung einstückig eingeformt ist.In order to provide sufficient stability for the jet regulator housing having a lateral insertion opening, it may be advantageous if a jet decomposing device, which is preferably configured as a perforated plate, is integrally formed in the jet regulator housing.
Um die dem Strahlzerleger nachfolgenden Funktionseinheiten in das Strahlreglergehäuse einschieben zu können, ist es vorteilhaft, wenn die Strahlzerlegeeinrichtung zuströmseitig vor der Einschuböffnung in das Strahlreglergehäuse eingeformt ist.In order to be able to insert the functional units following the jet splitter into the jet regulator housing, it is advantageous if the jet splitting device is formed on the inflow side upstream of the insertion opening into the jet regulator housing.
Um unerwünschte Kriechströme zwischen dem Strahlregler einerseits und dem Armatureninnenumfang andererseits zu vermeiden, ist es zweckmäßig, wenn zwischen dem Strahlregler und dem Armatureninnenumfang eine Ringdichtung, eine Lippendichtung oder dergleichen umlaufendes Dichtungselement vorgesehen ist.In order to avoid unwanted leakage currents between the aerator on the one hand and the valve inner circumference on the other hand, it is expedient if an annular seal, a lip seal or the like encircling sealing element is provided between the aerator and the valve inner circumference.
Ein solches Dichtungselement kann gut zwischen das Strahlreglergehäuse einerseits und den Armatureninnenumfang andererseits dichtend eingefügt werden, ohne das Strahlreglergehäuse dabei zu verformen, wenn das Strahlreglergehäuse im Bereich der Strahlzerlegeeinrichtung ein am Armaturenumfang dichtend anliegendes Dichtungselement trägt.Such a sealing element can be inserted sealingly between the jet regulator housing, on the one hand, and the fitting inner circumference, without deforming the jet regulator housing, when the jet regulator housing carries a sealing element sealingly fitting the fitting circumference in the area of the jet disintegrating device.
Um einen unerwünschten Wasseraustritt aus der Einschuböffnung des Strahlreglergehäuses zu vermeiden und um eine unkontrollierte Luftansaugung durch die Einschuböffnung zu verhindern, ist es vorteilhaft, wenn zwischen der Einschuböffnung und dem Armatureninnenumfang eine Dichtung vorgesehen ist.In order to avoid unwanted leakage of water from the insertion opening of the jet regulator housing and to prevent uncontrolled air intake through the insertion opening, it is advantageous if a seal is provided between the insertion opening and the valve inner circumference.
Dabei sieht eine besonders einfache und mit geringem Aufwand herstellbare Ausführungsform gemäß der Erfindung vor, dass die Dichtung zumindest bereichsweise als eine an das Strahlreglergehäuse einstückig angeformte Dichtlippe oder dergleichen Dichtungsvorsprung ausgestaltet ist.Here, a particularly simple and producible with little effort embodiment according to the invention provides that the seal is at least partially configured as a integrally formed on the jet regulator housing sealing lip or the like sealing projection.
Da die Einschuböffnung an ihrem zuströmseitigen Randbereich auch bereits durch das um das Strahlreglergehäuse umlaufende Dichtungselement abgedichtet werden kann, kann es ausreichend sein, wenn die Dichtlippe oder dergleichen Dichtungsvorsprung sich linienförmig über den die Einschuböffnung begrenzenden Umfangsrandbereich des Strahlreglergehäuses beidseits bis in den Bereich des Dichtungselements erstreckt.Since the insertion opening at its inflow-side edge region can already be sealed by the sealing element surrounding the jet regulator housing, it can be sufficient be, when the sealing lip or the like sealing projection extends linearly over the insertion opening bounding peripheral edge region of the jet regulator housing on both sides into the region of the sealing element.
Eine Ausführungsform gemäß der Erfindung sieht vor, dass zum Verschließen der Einschuböffnung ein Deckel vorgesehen ist, und dass zumindest ein Einsetzteil wenigstens einen Teilbereich des Deckels trägt. Werden die benötigten Einsetzteile in die Einschuböffnung eingeschoben, so verschließen die an diesen Einsetzteilen vorgesehenen Teilbereiche des Deckels die Einschuböffnung letztendlich vollständig.An embodiment according to the invention provides that a cover is provided for closing the insertion opening, and that at least one insertion part carries at least a portion of the cover. If the required insertion parts are inserted into the insertion opening, then the partial areas of the cover provided on these insertion parts ultimately close the insertion opening completely.
Um die Einschuböffnung auch ausreichend dicht zu verschließen, ist es zweckmäßig, wenn an den Deckel oder wenigstens einem Deckelteilbereich mindestens ein Anpressvorsprung angeformt ist, der den Armatureninnenumfang beaufschlagt. Der am Armatureninnenumfang anliegende Anpressvorsprung, der beim Einschieben des Strahlreglers in das Armaturengehäuse radial nach innen gepresst wird, presst seinerseits den Deckel oder Deckelteilbereich dicht gegen das Strahlreglergehäuse.In order to close the insertion opening sufficiently tight, it is expedient if at least one Anpressvorsprung is formed on the lid or at least one lid portion, which acts on the valve inner circumference. The fitting on the inside of the fitting Anpressvorsprung, which is pressed radially radially inwardly upon insertion of the jet regulator in the valve body, in turn presses the lid or lid portion tight against the jet regulator housing.
Um die einfache Herstellung des erfindungsgemäßen Strahlreglers noch zu begünstigen, ist es vorteilhaft, wenn der mindestens eine Anpressvorsprung im Bereich des Einsetzteiles an den Deckel oder Deckelteilbereich angeformt ist.In order to further favor the simple production of the jet regulator according to the invention, it is advantageous if the at least one pressing projection in the region of the insert part is molded onto the cover or cover part region.
Um ein Verrutschen oder Lösen der in das Strahlreglergehäuse eingeschobenen Einsetzteile zu verhindern, kann es vorteilhaft sein, wenn zumindest ein Einsetzteil in seine Einschubführung mittels Klemmsitz gesichert oder gehalten ist.In order to prevent slippage or loosening of the inserted into the jet regulator housing insert parts, it may be advantageous if at least one insert part is secured or held in its insertion guide by means of a press fit.
Um unerwünschte Manipulationen an den im Gehäuseinneren des Strahlreglergehäuses befindlichen Einsetzteilen zu verhindern, kann es vorteilhaft sein, wenn in das Strahlreglergehäuse auslaufseitig eine Sieb-, Gitter- oder Netzstruktur einstückig angeformt ist. Die an das Strahlreglergehäuse auslaufseitig einstückig angeformte Sieb-, Gitter oder Netzstruktur kann nicht nur strahlformend wirken, sondern übernimmt gleichzeitig auch die Funktion einer Manipulationssicherung.To avoid unwanted manipulation of the inside of the housing It can be advantageous if the jet regulator housing has a screen, grid or net structure integrally formed on its outlet side in the jet regulator housing. The outlet, on the outlet side integrally formed on the jet regulator housing screen, grid or network structure can not only act jet-forming, but also takes over the function of a tamper-proof.
Um den vorzugsweise vollständig in das Armaturengehäuse eingeschobenen Strahlregler bei Bedarf auch wieder aus dem Armaturengehäuse entfernen zu können, ist es zweckmäßig, wenn am Strahlreglergehäuse vorzugsweise im Bereich des Belüftungskanals zumindest eine Werkzeugangriffsstelle für ein Demontagewerkzeug vorgesehen ist.In order to be able to remove the jet regulator, which is preferably fully inserted into the fitting housing, from the fitting housing, it is expedient if at least one tool engagement point for a dismantling tool is provided on the jet regulator housing, preferably in the region of the ventilation channel.

Es kann vorteilhaft sein, den dem Wasserstrom entgegengesetzten Widerstand an den Seitenrändern der Einsetzteile 15 höher zu gestalten. Dazu können an den Seitenrändern der Einsetzteile 15 eine höhere Anzahl von, die Sieb- oder Gitterstruktur bildenden Stegen vorgesehen sein, so dass nur eine geringere Wassermenge passieren und ein Spritzen des austretenden Wasserstrahls am Strahlumfang vermieden, zumindest aber verringert werden kann. Werden stattdessen an den Seitenrändern der Einsetzteile 15 eine geringere Anzahl von Stegen vorgesehen, und wird dadurch der dem Wasserstrahl entgegengesetzte Widerstand im Bereich der Seitenränder der Einsetzteile vermindert, kann die zylindrische Form des austretenden Wasserstrahls über eine längere Distanz sichergestellt werden, was insbesondere bei langgestreckten Strahlreglern wünschenswert ist.It may be advantageous to make the opposite to the water flow resistance at the side edges of the
