Description

Die Erfindung betrifft einen Strahlregler mit einer Strahlzerlegeeinrichtung sowie mit einer in Strömungsrichtung auf Abstand nachgeschalteten und die auslaufseitige Stirnseite des Strahlreglers bildenden Strahlreguliereinrichtung, die auslaufseitig eine Lochplatte aufweist, welche zumindest in wenigstens einem als Lochfeld ausgebildeten Teilbereich ihrer quer zur Strömungsrichtung orientierten Plattenebene mehrere Durchflußlöcher hat, deren benachbarte Durchflüßlöcher voneinander trennenden und sich etwa in Strömungsrichtung erstreckenden Führungswandungen jeweils eine Wandstärke aufweisen, welche einen Bruchteil des lichten Lochdurchmessers eine von den Führungswandungen begrenzten Durchflußloches beträgt, wobei die Strahlzerlegeeinrichtung sowie die Strahlreguliereinrichtung in einem Strahlreglergehäuse des Strahlreglers angeordnet sind.The invention relates to a jet regulator with a jet splitting device as well as with a distance in the direction of flow downstream and the outlet end of the Jet regulator forming jet regulator, the has a perforated plate on the outlet side, which at least in at least one portion of it designed as a perforated field several plate plane oriented transversely to the flow direction Has flow holes, their adjacent flow holes separating and approximately in the direction of flow extending guide walls each have a wall thickness have a fraction of the clear hole diameter a flow hole delimited by the guide walls is, the beam splitting device and the beam regulating device in a jet regulator housing of the jet regulator are arranged.

Aus der EP 0 721 031 A1 ist bereits ein Strahlregler der eingangs erwähnten Art bekannt, der in seinem Strahlreglergehäuse eine Strahlzerlegeeinrichtung sowie eine davon beabstandete und die auslaufseitige Stirnseite des Strahlreglers bildende Strahlreguliereinrichtung hat. Während die zuströmseitige Strahlzerlegeeinrichtung durch eine Scheibe gebildet ist, die eine in radialer Richtung zur Durchströmöffnungen orientierte labyrinthartige Strömungsführung hat, ist die abströmseitige Strahlreguliereinrichtung als Lochplatte ausgebildet, die eine Vielzahl von Durchflußlöchern aufweist. Dabei ist in der in Figur 22 der EP 0 721 031 A1 dargestellten Ausführungsform des vorbekannten Strahlreglers die Lochplatte so bemessen, daß die benachbarte Durchflußlöcher voneinander trennenden und sich etwa in Strömungsrichtung erstreckenden Führungswandungen jeweils eine Wandstärke aufweisen, welche einen Bruchteil des lichten Lochdurchmessers eines von den Führungswandungen begrenzten Durchflußloches beträgt.A jet regulator is already known from EP 0 721 031 A1 known type mentioned in his jet regulator housing a beam splitter and a spaced apart and the outlet-side end face of the jet regulator Has jet regulating device. While the upstream Beam splitting device is formed by a disc that one oriented in the radial direction to the flow openings has labyrinthine flow, is the downstream Beam regulating device designed as a perforated plate, the one Has a plurality of flow holes. It is in the in Figure 22 of the embodiment of EP 0 721 031 A1 Known jet regulator dimension the perforated plate so that the Adjacent and separate flow holes approximately in the flow direction extending guide walls each have a wall thickness which is a fraction of the inside Hole diameter of a limited by the guide walls Flow hole is.

Der aus EP 0 721 031 A1 vorbekannte Strahlregler hat jedoch den Nachteil, daß seine als Strahlreguliereinrichtung dienende Lochplatte, welche die in der Strahlzerlegeeinrichtung vereinzelten Wasserstrahlen nach dem Belüften im Strahlregler zu einem homogenen weichen Wasserstrahl zusammenführen soll, vergleichsweise dick ausgebildet ist. Eine derart dicke Lochplatte erschwert nicht nur die Herstellung eines solchen Strahlreglers beim Entformen der als Spritzgußteil ausgebildeten Lochplatte sowie die Ausgestaltung dieses Strahlreglers in normgerechten Abmessungen; vielmehr bildet eine solche dicke Lochplatte auch einen langen Führungsweg, aus dem die Wasserstrahlen überwiegend noch als Einzelstrahlen ausströmen.However, the jet regulator previously known from EP 0 721 031 A1 has the disadvantage that its serving as a jet regulating device Perforated plate, which in the jet cutting device isolated water jets after aerating in the jet regulator to form a homogeneous soft water jet, is comparatively thick. Such a thick one Perforated plate not only complicates the manufacture of such Jet regulator when demoulding the injection molded part Perforated plate and the design of this jet regulator in standardized dimensions; rather it forms such a thickness Perforated plate also has a long path from which the water jets predominantly flow out as single jets.

Aus der DE 30 00 799 C2 ist bereits ein Strahlregler bekannt, der in seinem Strahlreglergehäuse eine als Lochplatte ausgebildete Strahlzerlegeeinrichtung aufweist. Dieser Strahlzerlegeeinrichtung ist auslaufseitig eine Strahlreguliereinrichtung nachgeordnet. Das zuströmende Wasser wird in der Strahlzerlegeeinrichtung in einzelne Wasserstrahlen aufgeteilt, die in der Strahlreguliereinrichtung wieder zu einem homogenen, perlend-weichen Wasserstrahl gebündelt werden. Dabei wird die Strahlreguliereinrichtung des vorbekannten Strahlreglers aus mehreren, geringfügig voneinander beabstandeten Drahtsieben gebildet, die eine unterschiedliche Maschenweite haben und deren Sieböffnungen als Durchflußlöcher dienen.A jet regulator is already known from DE 30 00 799 C2, the one in its jet regulator housing is designed as a perforated plate Has beam splitting device. This beam splitter is a jet regulator on the outlet side subordinate.

The jet regulating device of the known jet regulator from several, slightly spaced wire screens formed that have a different mesh size and their sieve openings serve as flow holes.

Die Herstellung dieser Strahlreguliersiebe und deren Montage in das Strahlreglergehäuse ist mit einem nicht unerheblichen Aufwand verbunden. Darüber hinaus sind solche Siebe empfindlich gegen ein Verkalken oder Verschmutzen durch die im Wasser mitgeführten Inhaltstoffe. The manufacture of these jet regulating screens and their assembly in the jet regulator housing with a not inconsiderable Associated effort. Such screens are also sensitive against calcification or contamination by those in the water carried ingredients.

Aus der US 2 744 738 A ist bereits ein Strahlregler bekannt, der eine topfförmige Strahlzerlegeeinrichtung mit mehreren umfangs- oder stirnseitigen Durchflußlöcher hat. Der Strahlzerlegeeinrichtung ist in Strömungsrichtung eine Strahlreguliereinrichtung auf Abstand nachgeschaltet, die aus zumindest einer, im Querschnitt sternförmig gewellten Metallhülse besteht, deren Hülsenöffnung in Strömungsrichtung orientiert ist. Im Zentrum einer äußeren Metallhülse kann auch eine weitere innere Metallhülse angeordnet sein, die ebenfalls einen sternförmig gewellten Querschnitt aufweist. Der in der Wasserarmatur zum Strahlregler strömende Wasserstrahl wird in der Strahlzerlegeeinrichtung in mehrere Einzelstrahlen unterteilt, die anschließend in den zwischen dem äußeren Mundstück und den Metallhülsen gebildeten Führungskanälen mit der einströmenden Luft durchmischt werden.A jet regulator is already known from US Pat. No. 2,744,738 A, which is a pot-shaped jet cutting device with several has circumferential or frontal flow holes. The jet cutting device is a jet regulating device in the direction of flow at a distance, consisting of at least one, there is a star-shaped corrugated metal sleeve, the Sleeve opening is oriented in the direction of flow. Downtown An outer metal sleeve can also be an inner one Metal sleeve can be arranged, which is also a star-shaped has a corrugated cross section. The one in the water tap for Jet regulator flowing water jet is in the jet splitting device divided into several individual beams, which then in the between the outer mouthpiece and the metal sleeves formed guide channels mixed with the inflowing air become.

Die große Längserstreckung der Metallhülsen bewirkt zwar eine gute Strömungsführung der in den Führungskanälen geführten Einzelstrahlen, jedoch wird dadurch gleichzeitig auch die Erzeugung eines weichen perlenden Gesamtstrahles erschwert. Darüber hinaus ist die Luftdurchmischung der Einzelstrahlen in der Strahlreguliereinrichtung des vorbekannten Strahlreglers verbesserungswürdig. Schließlich erfordert die Herstellung und Montage des aus mehreren ineinandergefügten Teilen bestehenden Strahlreglers einen nicht unerheblichen Aufwand.The large longitudinal extension of the metal sleeves causes one good flow guidance of those guided in the guide channels Single rays, but this also makes the It is difficult to produce a soft, sparkling overall jet. In addition, the air mixing of the individual jets in the jet regulating device of the known jet regulator in need of improvement. After all, it requires manufacturing and Assembly of the consisting of several interlocked parts Jet regulator a not inconsiderable effort.

Aus der GB 2 104 625 A ist bereits eine Mischarmatur bekannt, bei der die Heißwasserleitung und die Kaltwasserleitung in einem gemeinsamen Mundstück enden. Das Mundstück weist mehrere Durchflußlöcher auf, die im wesentlichen auf Kreisbahnen angeordnet sind und jeweils einen kreissegmentförmigen Querschnitt haben. Während die auf der inneren Kreisbahn angeordneten Durchflußlöcher beispielsweise der Heißwasserleitung zugeordnet sind, fließt durch die auf der äußeren Kreisbahn angeordneten Durchflußlöcher das Kaltwasser. Durch die getrennte Kaltwasser- und Warmwasserführung bis zum Mundstück werden auch bei Wasserdruck-Schwankungen unerwünschte Kreuzflüsse vermieden. Die Erzeugung eines perlend-weichen Wasserstrahls in dem ebenfalls vergleichsweise hohen Mundstück der vorbekannten Mischarmatur ist demgegenüber nicht ohne weiteres möglich.A mixer tap is already known from GB 2 104 625 A, where the hot water pipe and the cold water pipe in one common mouthpiece ends. The mouthpiece has several Flow holes on, essentially on circular paths are arranged and each a segment of a circle Cross section. While on the inner circular path arranged flow holes, for example the hot water pipe are assigned flows through on the outer circular path arranged flow holes the cold water. By the separate Cold water and hot water flow to the mouthpiece are also undesirable cross flows avoided in the event of fluctuations in water pressure. The creation of a sparkling, soft water jet in the also comparatively high mouthpiece of the previously known In contrast, mixer tap is not easily possible.

Aus der EP 0 496 033 A kennt man bereits einen Strahlregler, dessen Strahlzerlegeeinrichtung aus zwei, in Strömungsrichtung voneinander beabstandeten Lochplatten besteht. Die auslaufseitige Stirnseite dieses vorbekannten Strahlreglers bilden auch hier - ähnlich wie in der eingangs erwähnten DE 30 00 799 C2 - drei Strahlreguliersiebe, die als Strahlreguliereinrichtung dienen. Der mit der Montage der Strahlreguliersiebe ohnehin schon hohe Herstellungsaufwand wird durch das Zusammenfügen und Ausrichten der aus den zwei Lochplatten bestehenden Strahlzerlegeeinrichtung noch zusätzlich erhöht.A jet regulator is already known from EP 0 496 033 A, whose jet splitting device consists of two, in the direction of flow spaced apart perforated plates. The outlet side The face of this known jet regulator also form here - Similar to DE 30 00 799 C2 - three - mentioned at the beginning Jet regulating screens that serve as jet regulating devices. The already high one with the installation of the jet regulating screens Manufacturing effort is due to the assembly and alignment the jet cutting device consisting of two perforated plates increased even further.

Der aus der EP 0 496 033 A vorbekannte Strahlregler weist ein Vorsatzsieb auf, wie es in ähnlicher Form auch aus der DE 43 33 549 A bekannt ist. Solche Vorsatzsiebe dienen lediglich als Schutzsiebe, um die Durchflußöffnungen in der Strahlzerlegeeinrichtung sowie der Strahlreguliereinrichtung des in Strömungsrichtung nachfolgenden Strahlreglers vor einem Verstopfen mit Schmutzteilchen zu schützen. Im Gegensatz zu den eingangs erwähnten Strahlreglern sind solchen Vorsatzsieben jedoch keine strahlformenden Funktionen zugewiesen.The jet regulator known from EP 0 496 033 A has one Attachment sieve, as in a similar form from DE 43 33 549 A is known. Such front screens only serve as Protective sieves around the flow openings in the jet separation device and the jet regulating device in the direction of flow subsequent jet regulator before clogging To protect dirt particles. In contrast to the beginning However, the jet regulators mentioned are not such attachment screens beam-shaping functions assigned.

Es besteht daher die Aufgabe, einen Strahlregler der eingangs erwähnten Art zu schaffen, der sich durch eine gute Strahlformung und hohe Funktionssicherheit auszeichnet und dennoch mit geringem Aufwand herstellbar ist.There is therefore the task of a jet regulator at the beginning to create the kind mentioned, which is characterized by good beam shaping and distinguishes high functional reliability and yet with can be produced with little effort.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere darin, daß das Verhältnis h:D zwischen der Höhe h der Führungswandungen und dem Gesamtdurchmesser D der Strahlreguliereinrichtung kleiner 3:21 ist, und daß am Strömungsaustrittsende des Strahlreglergehäuses hinter der Strahlreguliereinrichtung eine Gehäuseeinschnürung zur Strahlbündelung vorgesehen ist.The inventive solution to this problem consists in the Jet regulators of the type mentioned at the outset, in particular in that the ratio h: D between the height h of the guide walls and the overall diameter D of the jet regulating device is smaller 3:21, and that at the flow exit end of the jet regulator housing a constriction of the housing behind the jet regulating device is provided for beam bundling.

Das dem erfindungsgemäßen Strahlregler zuströmende Wasser wird in dessen Strahlzerlegeeinrichtung in Einzelstrahlen aufgeteilt, die anschließend, gegebenenfalls nach einer Luftdurchmischung, in der Strahlreguliereinrichtung zu einem homogenen weichen Gesamtstrahl zusammengefaßt werden. Diese Strahlreguliereinrichtung des erfindungsgemäßen Strahlreglers weist auslaufseitig eine Lochplatte auf, die zumindest in einem als Lochfeld ausgebildeten Teilbereich ihrer Plattenebene mehrere Durchflußlöcher hat. Während übliche Strahlreguliersiebe die zuströmenden Einzelstrahlen allenfalls über die Dicke ihres Drahtdurchmessers führen können, haben die Durchflußlöcher in der Strahlreguliereinrichtung des erfindungsgemäßen Strahlreglers mit ihren Führungswandungen eine demgegenüber größere Längserstreckung, so daß darin die einzelnen Wasserstrahlen aufgrund der länger einwirkenden Adhäsionskräfte besser formbar sind. Da die Lochplatte gleichzeitig aber auch so bemessen ist, daß das Verhältnis h:D zwischen der Höhe H der Führungswandungen und dem Gesamtdurchmesser D der Strahlreguliereinrichtung kleiner 3:21 ist, ist die Lochplatte so dünn und sind die Führungswandungen so kurz ausgestaltet, daß die Bildung eines perlenweichen Gesamtstrahles gefördert wird. Das gute Zusammenführen der Einzelstrahlen und die Bündelung dieser Einzelstrahlen zu einem geschlossenen zylindrischen Gesamtstrahl wird noch dadurch begünstigt, daß am Strömungsaustrittsende des Strahlreglergehäuses hinter der Strahlreguliereinrichtung eine Gehäuseeinschnürung zur Strahlbündelung vorgesehen ist. Da die Durchflußlöcher gleichzeitig nur durch die dünnen Führungswände voneinander getrennt sind und entsprechend eng aneinander anliegen, vereinen sich die Einzelstrahlen nach Durchlaufen der Strahlreguliereinrichtung zu einem sprudelnd-weichen, homogenen und nur wenig streuenden Gesamtstrahl. Dabei läßt sich die Lochplatte dieser Strahlreguliereinrichtung beispielsweise als Spritzguß- oder Strangpreßteil aus Kunststoff oder jedem anderen geeigneten Werkstoff kostengünstig herstellen. Durch ihren homogenen Aufbau neigt die Lochplatte des erfindungsgemäßen Strahlreglers weniger zum Verkalken oder Verschmutzen durch die im Wasser mitgeführten Inhaltsstoffe, wodurch die Funktionssicherheit des erfindungsgemäßen Strahlreglers wesentlich begünstigt wird.The water flowing to the jet regulator according to the invention becomes divided into individual beams in its beam splitting device, which then, if necessary after air mixing, in the jet regulating device to a homogeneous soft Total beam can be summarized. This jet regulator of the jet regulator according to the invention has on the outlet side a perforated plate, at least in one as a perforated field trained portion of their plate level several flow holes Has. While usual jet regulating screens incoming individual beams at most over the thickness of their Can lead wire diameter, have the flow holes in the jet regulating device of the jet regulator according to the invention with its guide walls, on the other hand, a greater longitudinal extension, so that due to it the individual water jets the longer-lasting adhesive forces are easier to shape. Since the perforated plate is also dimensioned so that the ratio h: D between the height H of the guide walls and the overall diameter D of the jet regulating device is smaller 3:21, the perforated plate is so thin and are the guide walls designed so short that the formation of a pearl soft Total beam is promoted. The good merging of the individual rays and the bundling of these individual rays this creates a closed cylindrical total jet favors that at the flow exit end of the jet regulator housing a constriction of the housing behind the jet regulating device is provided for beam bundling. Since the Flow holes at the same time only through the thin guide walls are separated from each other and accordingly close to each other the individual beams come together after passing through the jet regulating device into a bubbly-soft, homogeneous and little scattering total beam. It leaves the perforated plate of this jet regulating device, for example as an injection molded or extruded part made of plastic or manufacture any other suitable material inexpensively. Due to its homogeneous structure, the perforated plate of the invention tends Jet regulator less for calcification or soiling through the ingredients carried in the water, which makes the Functional reliability of the jet regulator according to the invention is significantly favored.

Um den Wasserstrom an einer möglichst großen Wandungsfläche der in der Lochplatte vorgesehenen Führungswandungen optimal formen zu können, ist es zweckmäßig, wenn die Lochplatte möglichst viele Durchflußöffnungen hat. Dazu sieht eine Ausführungsform gemäß der Erfindung vor, daß die Durchflußlöcher der Lochplatte einen runden, gerundeten, kreissegmentartigen oder eckigen Durchflußquerschnitt haben.Around the water flow on the largest possible wall surface the guide walls provided in the perforated plate optimal To be able to shape, it is useful if the perforated plate has as many flow openings as possible. One sees Embodiment according to the invention that the flow holes the perforated plate a round, rounded, segment-like or have an angular flow cross-section.

Eine bevorzugte Weiterbildung gemäß der Erfindung von eigener schutzwürdiger Bedeutung sieht vor, daß die Durchflußlöcher zumindest im Zentrumsbereich der Lochplatte einen sechseckigen Durchflußquerschnitt haben und daß die Lochplatte vorzugsweise im wesentlichen über ihre gesamte Plattenebene als insbesondere wabenzellenartiges Lochfeld ausgebildet ist. Eine solche, aus sechseckigen Durchflußlöchern wabenzellenartig ausgebildete Lochplatte vermag den Wasserstrahl besonders gut zu formen, ohne ihm gleichzeitig einen störenden Strömungswiderstand entgegenzusetzen.A preferred further development according to the invention of its own of protection importance provides that the flow holes a hexagonal one at least in the central area of the perforated plate Flow cross-section and that the perforated plate preferably essentially over their entire plate level as particular honeycomb-like perforated field is formed. Such, from hexagonal flow holes formed like a honeycomb cell Perforated plate is particularly good at shaping the water jet, without a disturbing flow resistance at the same time to oppose.

Möglich ist aber auch, daß die Lochplatte in einer äußeren Ringzone kreissegmentförmige Durchflußlöcher hat, wobei diese äußere Ringzone ein wabenzellenartig ausgestaltetes Lochfeld mit im Querschnitt sechseckigen Durchflußlöchern umgrenzt.But it is also possible that the perforated plate in an outer Ring zone has circular segment-shaped flow holes, these outer ring zone a honeycomb-like perforated field bounded by hexagonal flow holes.

Das Zusammenfließen der aus der Strahlreguliereinrichtung austretenden Einzelstrahlen zu einem homogenen Gesamtstrahl wird wesentlich begünstigt, wenn die auslaufseitigen Kanten der die Durchflußlöcher begrenzenden Führungswandungen gerundet sind.The confluence of the from the jet regulator emerging individual beams to a homogeneous total beam is significantly favored if the edges on the outlet side the guide walls delimiting the flow holes are rounded are.

Die Lochplatte eines erfindungsgemäßen Strahlreglers kann jedem üblichen Strahlzerlegesystem nachgeschaltet werden. Bei Verwendung solcher Strahlzerlegesysteme, in denen das zuströmende Wasser beim Aufteilen in die Einzelstrahlen weniger stark abgebremst wird, kann es zweckmäßig sein, wenn die Strahlreguliereinrichtung ein Strahlreguliersieb oder mehrere Strahlreguliersiebe hat, welche der Lochplatte zuströmseitig vorgeschaltet sind. Durch die Verwendung einer auslaufseitigen Lochplatte in der Strahlreguliereinrichtung des erfindungsgemäßen Strahlreglers kann nicht nur das Ergebnis der Strahlformung verbessert, sondern auch die Anzahl der benötigten Strahlreguliersiebe reduziert werden, was die Herstellung eines solchen Strahlreglers wesentlich vereinfacht.The perforated plate of a jet regulator according to the invention can be used by anyone usual jet cutting system can be connected. At Use of such jet cutting systems in which the inflowing Water less when split into individual jets is braked, it may be useful if the jet regulating device one or more jet regulating screens Jet regulating sieves has which of the perforated plate upstream are connected upstream. By using an outlet side Perforated plate in the jet regulating device of the invention Jet regulator can not only be the result of beam shaping improved, but also the number of needed Jet regulating screens are reduced, which is the manufacture of a such jet regulator significantly simplified.

Um den Herstellungsaufwand noch zusätzlich zu reduzieren, kann es vorteilhaft sein, wenn die Lochplatte integraler Bestandteil eines Strahlreglergehäuses ist und wenn die Lochplatte dazu vorzugsweise einstückig mit dem Strahlreglergehäuse verbunden ist. Bei einer solchen Ausführungsform, bei der die Lochplatte vorgesehen ist, die eine Positionieröffnung an dem einen Element des Strahlreglers hat, in die ein am anderen Element vorgesehener Positioniervorsprung einsetzbar ist. Bei einer zentralen Anordnung der Positionieröffnung sowie des damit zusammenwirkenden Positioniervorsprunges können die beiden Einbauteile praktisch koaxial zueinander angeordnet werden. Dabei kann es vorteilhaft sein, wenn wenigstens ein Abstandhalter gleichzeitig auch als Positioniervorsprung oder als Auswerferpunkt beziehungsweise als Auswerferanformung vorgesehen ist. Um die Lochplatte gegenüber einem vorgeschalteten Element des Strahlreglers auch in Umfangsrichtung genau plazieren zu können, kann die Positionieröffnung einen unrunden lichten Querschnitt haben, an den der Positioniervorsprung formangepaßt ist.To further reduce the manufacturing effort, can it be advantageous if the perforated plate is an integral part of a jet regulator housing and if the perforated plate is added preferably connected in one piece to the jet regulator housing is. In such an embodiment, in which the perforated plate is provided which has a positioning opening on the one element of the jet regulator, into which one is provided on the other element Positioning projection can be used. At a central arrangement of the positioning opening and thus interacting positioning projection, the two Installation parts can be arranged practically coaxially with each other. It can be advantageous if at least one spacer at the same time as a positioning projection or as an ejector point or is provided as an ejector molding. To the perforated plate opposite an upstream element of the To be able to place the jet regulator precisely in the circumferential direction, the positioning opening can have an out-of-round cross-section to which the positioning projection is form-matched.

Eine besonders vorteilhafte Ausführungsform gemäß der Erfindung sieht vor, daß die Strahlreguliereinrichtung quer zur Durchströmrichtung verlaufende Stege oder Stifte aufweist, welche der Lochplatte der Strahlreguliereinrichtung vorgeschaltet sind. Die aus der Strahlzerlegeeinrichtung ausströmenden Einzelstrahlen können zwischen den quer zur Durchströmrichtung verlaufenden Stegen oder Stiften wirkungsvoll abgebremst werden, um sie anschließend in der in Strömungsrichtung nachgeschalteten Lochplatte zu einem weichen homogenen Gesamtstrahl zu bündeln. Dabei neigen die quer zur Durchströmrichtung verlaufenden Stege oder Stifte der Strahlreguliereinrichtung weniger zu einer Verkalkung, wie sie bei herkömmlichen Strahlreguliersieben vor allem an den Kreuzungspunkten der Gitternetzstruktur der einzelnen Siebe entsteht. Mit den quer zur Strömungsrichtung orientierten Stegen oder Stiften läßt sich dennoch auch bei hohen Literleistungen eine ausreichende Strahl-Vorregulierung erreichen, um eine normgerechte Geräuschentwicklung zu gewährleisten.A particularly advantageous embodiment according to the invention provides that the jet regulating device transversely to the flow direction has extending webs or pins, which the Perforated plate are upstream of the jet regulating device. The individual jets flowing out of the jet splitting device can between those running transversely to the flow direction Bridges or pins are effectively slowed down to them then downstream in the flow direction Bundle the perforated plate into a soft, homogeneous overall jet. The webs, which run transversely to the flow direction, tend or pins of the jet regulating device less to one Calcification, as is the case with conventional jet regulating screens especially at the crossing points of the grid structure of the individual sieves are created. With the cross to the flow direction oriented bars or pens can still be used high pre-regulation of high liter capacities achieve in order to achieve a standard-compliant noise development guarantee.

Insbesondere bei einem Strahlregler mit Luftansaugung läßt sich eine besonders gute und wirkungsvolle Strahlregulierung erreichen, wenn insbesondere parallel zueinander angeordnete Stifte vorzugsweise rostartig in wenigstens einer quer zur Durchströmrichtung orientierten Ebene nebeneinander angeordnet sind und wenn insbesondere mehrere Stiftlagen in zueinander beabstandeten Ebenen in Durchströmrichtung übereinander angeordnet sind. Während dabei die der Strahlzerlegeeinrichtung zugewandten Stiftlagen die von der Strahlzerlegeplatte erzeugten Einzelstrahlen zur Luftdurchmischung aufreißen, können die Stifte in einer abströmseitigen Stiftlage so voneinander beabstandet werden, daß eine funktionsbeeinträchtigende Verkalkung vermieden wird und sich eventuell eine den Strahlregler verschließende Wasserschicht bilden kann, mit der sich ein die Verkalkung auch auf den zuströmseitig vorgeschalteten Stiftlagen verhindernder Luftabschluß erreichen läßt.In particular with a jet regulator with air intake particularly good and effective jet regulation achieve when in particular arranged parallel to each other Pins preferably rust-like in at least one across Flow-oriented plane arranged side by side are and if in particular several pin positions in each other spaced planes one above the other in the flow direction are arranged. While doing that the beam splitter facing pin positions the generated by the jet cutting plate The pins can tear open individual jets for air mixing spaced apart in a downstream pin position be that a functionally impaired calcification avoided and possibly one that closes the aerator Can form water layer, with which the calcification also preventing on the upstream pin positions Can achieve air exclusion.

Eine bevorzugte Ausführungsform, die sich durch eine besonders wirkungsvolle Strahlführung und Strahl-Vorregulierung auszeichnet, sieht vor, daß zumindest zwei benachbarte Stiftlagen quer zur Durchströmrichtung seitlich versetzte Stifte aufweisen und daß die Stifte einer stromabwärts angeordneten Stiftlage in dem durch die Stifte einer stromaufwärts benachbarten Stiftlage gebildeten Strömungsweg angeordnet sind. Dabei wird eine kontrollierte und gleichmäßige Strahlregulierung begünstigt, wenn der Abstand benachbarter Stifte einer Stiftlage gleich ist.A preferred embodiment, which is characterized by a special distinguishes effective beam guidance and beam pre-regulation, provides that at least two adjacent pin layers crossways have laterally offset pins to the flow direction and that the pins of a downstream pin position in by the pins of an upstream pin layer formed flow path are arranged. Doing so controlled and even jet regulation favors, if the distance between adjacent pins is the same as a pin position is.

Vorteilhaft ist es, wenn der Abstand von zuströmseitig angeordneten, benachbarten Stiftlagen kleiner ist, als der Abstand von stromabwärts angeordneten, benachbarten Stiftlagen und wenn die austrittsseitig befindliche Stiftlage Stifte mit einem Achsabstand zueinander und zu Stiften der benachbarten Stiftlage von vorzugsweise mehr als 0,8 mm aufweist. It is advantageous if the distance from the inflow side arranged, adjacent pin positions is smaller than that Distance from neighboring pin positions arranged downstream and if the pin position on the outlet side has pins a center distance to each other and to pins of the neighboring Pin position of preferably more than 0.8 mm.

Um eine normgerechte Geräuschentwicklung der Auslaufvorrichtung zu begünstigen, kann es vorteilhaft sein, wenn die Stifte ein gerundetes oder dergleichen strömungsgünstiges Querschnittsprofil aufweisen und vorzugsweise ein kreisrundes oder ein mit ihrer längeren Querschnittserstreckung in Durchströmrichtung orientiertes, ovales, tropfenförmiges oder dergleichen längliches Querschnittsprofil haben.To ensure that the outlet device generates noise in accordance with the standards To favor it, it can be beneficial if the pens are one rounded or the like aerodynamic cross-sectional profile have and preferably a circular or one with their longer cross-sectional extent in the flow direction oriented, oval, teardrop-shaped or the like elongated Have cross-sectional profile.

Eine besonders wirkungsvolle Strahl-Vorregulierung läßt sich erreichen, wenn der Lochplatte der Strahlreguliereinrichtung mehrere Stiftlagen, vorzugsweise drei Stiftlagen, vorgeschaltet sind.A particularly effective beam pre-regulation can be reach if the perforated plate of the jet regulator several pin positions, preferably three pin positions, connected upstream are.

Zweckmäßig ist es, wenn die Druchtrittsöffnungen in der Strahlzerlegeplatte in Durchströmrichtung konisch verengend ausgebildet sind und zuströmseitig vorzugsweise einen Einlaufradius oder Einlaufkonus haben. Durch diesen Einlaufradius oder Einlaufkonus wird einem unerwünschten Strömungsabriß entgegengewirkt. Die konisch verengende Ausgestaltung der Durchtrittsöffnungen in der Strahlzerlegeplatte begünstigt einen klaren scharfen Wasserstrahl, dessen Geschwindigkeit im Bereich der Stiftreihen reduziert wird und der sich besonders gut mit Luft anreichern läßt.It is useful if the passage openings in the Jet separating plate conically narrowing in the direction of flow are formed and preferably an inlet radius on the inflow side or have an inlet cone. Through this inlet radius or inlet cone becomes an undesirable stall counteracted. The conically narrowing design of the Passages in the jet disassembly plate favor one clear sharp water jet, its speed in the range the rows of pens is reduced and which goes particularly well with Allows air to accumulate.

Eine wirkungsvolle und kompakte Ausgestaltung der Strahlreguliereinrichtung wird begünstigt, wenn die Stifte der zuströmseitig ersten Stiftlage etwa in Fluchtrichtung zu den Lochachsen der Durchtrittsöffnungen in der Strahlzerlegeplatte angeordnet sind.An effective and compact design of the jet regulating device is favored when the pens of inflow side first pin position approximately in the direction of escape to the Hole axes of the passage openings in the jet cutting plate are arranged.

In den Fig. 1 bis 6 sind verschiedene Strahlregler in unterschiedlichen Ausführungsformen dargestellt. Diese Strahlregler sind in ein hier nicht dargestelltes Auslaufmundstück einsetzbar, welches an einer Sanitär-Auslaufarmatur montiert werden kann.1 to 6 different jet regulators are in different embodiments shown. This Flow regulators are in an outlet mouthpiece, not shown here can be used, which on a sanitary outlet fitting can be assembled.

Die in den Fig. 1 bis 6 dargestellten Strahlregler 10, 20, 30, 40, 70 und 80 weisen eine Strahlreguliereinrichtung 1 auf, die auslaufseitig eine Lochplatte 2 hat. Die Lochplatte 2 ist jeweils im wesentlichen über die gesamte, quer zur Strömungsrichtung orientierte Plattenebene wabenzellenartig ausgebildet.The jet regulators 10, 20, 30 shown in FIGS. 40, 70 and 80 have a jet regulating device 1 which has a perforated plate 2 on the outlet side. The perforated plate 2 is each essentially over the entire, transverse to the direction of flow oriented plate level formed like a honeycomb cell.

Wie aus den Fig. 1a bis 4a deutlich wird, wird die Wabenzellenstruktur der in den Strahlreglern 10 bis 80 verwendeten Lochplatte 2 durch eine Vielzahl von Durchflußlöchern 3 gebildet, deren aneinander angrenzenden und sich etwa in Strömungsrichtung erstreckenden Führungswandungen 4 jeweils eine Wandstärke s aufweisen, welche einen Bruchteil des lichten Lochdurchmessers w eines von den Führungswandungen 4 begrenzten Durchflußloches 3 beträgt. Dabei wird die auslaufseitige Stirnseite der Strahlregler 10 bis 80 jeweils im wesentlichen durch die Lochplatte 2 gebildet. Die Führungswandungen 4 sind auf ihrer Zuströmseite scharfkantig ausgebildet; auf der Abströmseite sind die Führungswandungen gerundet oder gefast, um ein Zusammenführen der Wasserstrahlen zu begünstigen.As is clear from FIGS. 1a to 4a, the honeycomb cell structure that used in the jet regulators 10 to 80 Perforated plate 2 formed by a plurality of flow holes 3, their adjacent and approximately in the direction of flow extending guide walls 4 each have a wall thickness s have a fraction of the clear hole diameter w of a flow hole delimited by the guide walls 4 3 is. The outlet side of the Flow regulators 10 to 80 each essentially by the Perforated plate 2 formed. The guide walls 4 are on their Inflow side with sharp edges; on the downstream side are the guide walls rounded or chamfered to a Favor merging of water jets.

Aus den Längsschnitten in den Fig. 1b bis 4b sowie aus den Fig. 5 und 6 wird deutlich, daß das Verhältnis h:D zwischen der Höhe h der Führungswandungen und dem Gesamtdurchmesser D (vgl. Fig. 1b) der Strahlreguliereinrichtungen 10, 20, 30, 40, 70 und 80 kleiner 1 ist. Dabei wird ein Verhältnis h:D kleiner 3:21, vorzugsweise im Bereich 1,5 : 15 bis 2 : 21 angestrebt. Trotz der gegenüber dem Gesamtdurchmesser D der Lochplatte vergleichsweise geringe Höhe h der Führungswandungen werden die Einzelstrahlen in der Strahlreguliereinrichtung 1 ausreichend geführt, um anschließend an der Auslaufstirnseite zu einem perlend-weichen homogenen Gesamtstrahl zusammengeführt werden zu können.From the longitudinal sections in FIGS. 1b to 4b and from 5 and 6 it is clear that the ratio h: D between the height h of the guide walls and the total diameter D (cf. FIG. 1b) of the jet regulating devices 10, 20, 30, 40, 70 and 80 is less than 1. A ratio h: D becomes smaller 3:21, preferably in the range 1.5: 15 to 2:21. Despite the compared to the total diameter D of the perforated plate comparatively low height h of the guide walls the individual beams in the beam regulating device 1 are sufficient led to one at the outlet end pearly-soft homogeneous overall jet can be brought together to be able to.

Besonders vorteilhaft ist es, wenn die Durchflußlöcher 3 der Lochplatten 2 einen lichten Lochdurchmesser oder ein Eckmaß w von 0,5 mm bis 2,5 mm haben. Während beispielsweise die Führungswandungen 4 der hier dargestellten Strahlregler 10 bis 80 jeweils eine Wandstärke s von etwa 0,25 mm haben, weisen die Durchflußlöcher einen lichten Lochdurchmesser w von etwa 1,25 mm auf. Dieser Lochdurchmesser ist so bemessen, daß die im Wasser mitgeführten Schmutzpartikel die Durchflußlöcher 3 passieren und die Funktion der Strahlreguliereinrichtung 1 nicht beeinträchtigen können. It when the flow holes 3 of the Perforated plates 2 have a clear hole diameter or a corner dimension w from 0.5 mm to 2.5 mm. For example, while the Guide walls 4 of the jet regulator 10 to shown here 80 each have a wall thickness s of approximately 0.25 mm the flow holes have a clear hole diameter w of about 1.25 mm. This hole diameter is dimensioned so that the the dirt holes carried in the water the flow holes 3 do not happen and the function of the jet regulating device 1 can affect.

Dabei können die Durchflußlöcher 3 einen runden, gerundeten (zum Beispiel eliptischen), kreissegmentartigen oder eckigen Lochquerschnitt haben. Bevorzugt wird eine Ausführungsform, bei der die Lochquerschnitte der Durchflußlöcher - wie hier - sechseckig ausgebildet sind, wobei die Seiten der aneinander angrenzenden Durchflußlöcher etwa parallel zueinander angeordnet sind.The flow holes 3 can be a round, rounded (for example elliptical), segment-like or angular Have hole cross-section. An embodiment is preferred where the hole cross sections of the flow holes - as here - are hexagonal, the sides of each other adjacent flow holes arranged approximately parallel to each other are.

Die in der Lochplatte 2 der Strahlregler 10 bis 80 vorgesehenen Durchflußlöcher 3 haben aufgrund der sie begrenzenden Führungswandungen 4 eine solche Längserstreckung, welche die einzelnen Wasserstrahlen aufgrund der länger einwirkenden Adhäsionskräfte besser zu formen vermag. Da die Durchflußlöcher 3 gleichzeitig nur durch die dünnen Führungswände 4 voneinander getrennt sind und entsprechend eng aneinander anliegen, vereinen sich die Einzelstrahlen nach Durchlaufen der Strahlreguliereinrichtung 1 zu einem homogenen, perlend-weichen, nicht-spritzenden vollen Wasserstrahl.The provided in the perforated plate 2 of the aerators 10 to 80 Flow holes 3 have due to the guide walls delimiting them 4 such a longitudinal extent, which the individual Water jets due to the longer acting adhesive forces better shape. Since the flow holes 3 at the same time are separated from each other only by the thin guide walls 4 and accordingly close to each other, they unite Single jets after passing through the jet regulating device 1 into a homogeneous, sparkling-soft, non-splashing full Water jet.

Dabei läßt sich die Lochplatte 2 der Strahlreguliereinrichtungen 1 beispielsweise als Spritzguß- oder Strangpreßteil aus Kunststoff oder jedem anderen geeigneten Werkstoff kostengünstig herstellen. Während bei den Strahlreglern 10, 30 und 80 gemäß den Fig. 1, 3 und 6 die Lochplatte 2 einstückig mit dem Strahlreglergehäuse 5 verbunden ist und dessen auslaufseitige Stirnseite bildet, wird bei den Strahlreglern 20, 40 und 70 gemäß den Fig. 2, 4 und 5 die Lochplatte 2 als separates Einbauteil in das Strahlreglergehäuse 5 eingesetzt. Am inneren Gehäusemantel des Strahlreglergehäuses 5 ist dazu eine als Ringflansch 6 ausgebildete Auflage vorgesehen, auf welcher die Lochplatte 2 von der zuströmseitigen Gehäuseöffnung aus aufsetzbar ist. Um das Handling einer solchen separaten Lochplatte zu erleichtern, ist es vorteilhaft, wenn die Lochplatte 2 eine ungelochte äußere und als Haltebereich dienende Ringzone hat.The perforated plate 2 of the jet regulating devices can thereby be used 1 for example as an injection molded or extruded part Plastic or any other suitable material inexpensively produce. While according to the jet regulators 10, 30 and 80 1, 3 and 6, the perforated plate 2 in one piece with the Jet regulator housing 5 is connected and its outlet side Forms the end face, is the case with the jet regulators 20, 40 and 70 2, 4 and 5, the perforated plate 2 as a separate Installation part used in the jet regulator housing 5. On the inside For this purpose, the housing jacket of the jet regulator housing 5 is a Ring flange 6 provided support on which the Perforated plate 2 from the upstream housing opening is attachable. To handle such a separate To facilitate perforated plate, it is advantageous if the Perforated plate 2 an unperforated outer and serving as a holding area Ring zone.

Die einfache Herstellung der Lochplatte 2 wird noch erleichtert, wenn die Lochplatte 2 im Bereich ihres wabenzellenartigen Lochfeldes mehrere - hier nicht weiter dargestellte - Auswerferpunkte oder Auswerferanformungen hat, die vorzugsweise kreisförmig und insbesondere in gleichen Abständen zueinander angeordnet sind.The simple manufacture of the perforated plate 2 is made even easier, if the perforated plate 2 in the area of its honeycomb cell Hole field several - not shown here - ejector points or ejector formations, which preferably circular and especially at equal distances from each other are arranged.

In Fig. 1 sowie insbesondere in den Fig. 2, 4 und 5 ist zu erkennen, daß zwischen der Lochplatte 2 und einem vorgeschalteten Element des Strahlreglers 20, 40 und 70 ein Abstandhalter 7 vorgesehen ist, welcher den Abstand zwischen der Lochplatte 2 und dem entgegen der Strömungsrichtung benachbarten Element sichert. Da die in Strömungsrichtung vorgeschalteten Elemente durch weitere Abstandhalter in einem definierten Abstand gehalten werden und da das zuströmseitig erste Element am Mündungsrand der hier nicht dargestellten Auslaufarmatur anliegt, können die in das Strahlreglergehäuse 5 eingesetzten Elemente einschließlich der Lochplatte 2 bei den Strahlreglern 20, 40 und 70 nicht unbeabsichtigt entgegen der Strömungsrichtung nach oben gedrückt werden.In Fig. 1 and in particular in Figs. 2, 4 and 5 is too recognize that between the perforated plate 2 and an upstream Element of the jet regulator 20, 40 and 70 a spacer 7th is provided, which is the distance between the perforated plate 2 and the element adjacent to the direction of flow backs up. Because the upstream elements kept at a defined distance by further spacers and there the first element on the inflow side at the edge of the mouth the outlet fitting, not shown here, can the elements used in the jet regulator housing 5 including the perforated plate 2 in the jet regulators 20, 40 and 70 not inadvertently counter to the direction of flow be pressed at the top.

Ebenso wie die bei den Strahlreglern 10, 30 und 80 einstückig mit dem Strahlreglergehäuse 5 verbundene Lochplatte 2 sichert die als separates Einbauteil eingesetzte Lochplatte 2 den entsprechenden Strahlregler 20, 40 und 70 gegen unberechtigte Manipulationen.Just like the one with the jet regulators 10, 30 and 80 with the jet regulator housing 5 connected perforated plate 2 secures the perforated plate 2 used as a separate installation part corresponding jet regulators 20, 40 and 70 against unauthorized persons Manipulations.

In Fig. 5 ist dargestellt, daß die an der Lochplatte 1 vorgesehenen drei Auswerferanformungen gleichzeitig auch als Abstandhalter 7 dienen. Diese Auswerferanformungen, von denen in Fig. 5 nur zwei zu sehen sind, sind auf einer Kreisbahn gleichmäßig voneinander beabstandet an der Zuströmseite der Lochplatte 2 angeordnet. Die Lochplatte 2 des in Fig. 5 dargestellten Strahlreglers 70 kann bei Bedarf auch einstückig an das Strahlreglergehäuse 5 angeformt sein.In Fig. 5 it is shown that the on the perforated plate 1st provided three ejector formations simultaneously as Serve spacers 7. These ejector formations, of which 5 only two can be seen are on a circular path evenly spaced from each other on the inflow side of the Perforated plate 2 arranged. The perforated plate 2 of the in Fig. 5th The jet regulator 70 shown can also be made in one piece if required be molded onto the jet regulator housing 5.

Die in den Fig. 1, 2, 3, 4, 5 und 6 dargestellten Strahlregler 10, 20, 30, 40, 70 und 80 weisen jeweils eine Strahlzerlegeeinrichtung 9 auf, welche das zuströmende Wasser in eine Vielzahl einzelner Wasserstrahlen aufteilt. Diese einzelnen Wasserstrahlen werden anschließend, nachdem sie mit der über die Gehäuseöffnungen 11 eindringenden Luft durchmischt wurden, in der abströmseitig nachgeschalteten Strahlreguliereinrichtung 1 zu einem perlend-weichen homogenen Gesamtstrahl geformt.The jet regulator shown in FIGS. 1, 2, 3, 4, 5 and 6 10, 20, 30, 40, 70 and 80 each have a beam splitting device 9 on which the incoming water in a variety divides individual water jets. These individual jets of water are then, after having the over the housing openings 11 penetrating air were mixed in the downstream jet regulating device 1 a pearly-soft, homogeneous overall jet.

Die in den Fig. 1 bis 6 dargestellten Strahlregler 10 bis 40 sowie 70 und 80 sind mit Luftbeimischung vorgesehen. Die Lochplatte 2 der Strahlreguliereinrichtung 1 ist jedoch auch bei solchen Strahlreglern und dergleichen sanitären Auslaufvorrichtungen vorteilhaft einsetzbar, die keine Luftbeimischung haben.The jet regulators 10 to 40 shown in FIGS. 1 to 6 as well as 70 and 80 are provided with air admixture. The Perforated plate 2 of the jet regulating device 1 is also, however in such jet regulators and the like sanitary outlet devices can be used advantageously without air admixture to have.

Mit der hier dargestellten Strahlreguliereinrichtung 1 sind alle bekannten Strahlzerlegesysteme vorteilhaft kombinierbar. So ist bei dem Strahlregler 70 gemäß Fig. 5 die Strahlzerlegeeinrichtung 9 als Prallverteilersystem ausgebildet, das zuströmseitig eine zylindrische Ausnehmung 13 hat. Diese zylindrische Ausnehmung 13 wird durch eine sich in axialer Richtung erstreckende Ringwandung 14 begrenzt, welche sternförmig angeordnete und zuströmseitig offene Durchtrittsöffnungen 15 hat. Diese Durchtrittsöffnungen 15 münden in einem äußeren Ringzonenbereich 16, durch den die Wasserstrahlen zur Strahlreguliereinrichtung 1 strömen können.With the jet regulating device 1 shown here all known jet cutting systems can be advantageously combined. 5 is the jet splitting device 9 designed as a baffle system, the has a cylindrical recess 13 on the inflow side. This cylindrical recess 13 is in an axial Direction extending ring wall 14, which is star-shaped arranged and open through-openings 15 Has. These through openings 15 open into an outer Ring zone area 16 through which the water jets to the jet regulating device 1 can flow.

Demgegenüber hat der Strahlregler 80 gemäß Fig. 6 eine als prallflächenfreies Lochplattensystem ausgebildete Strahlzerlegeeinrichtung 9. Während für die Strahlzerlegeeinrichtung gemäß Fig. 5 ein wirkungsvolles Aufreißen des Wasserstromes charakteristisch ist, zeichnet sich die Strahlzerlegeeinrichtung gemäß Fig. 6 durch eine normgerechte geringe Geräuschentwicklung aus.In contrast, the jet regulator 80 according to FIG. 6 has a baffle-free perforated plate system designed beam splitting device 9. While for the beam splitter according to Fig. 5 shows an effective tearing of the water flow the jet cutting device is characteristic 6 by a standard-compliant low noise out.

Die Strahlzerlegeeinrichtung 9 des Strahlreglers 80 gemäß Fig. 6 hat eine als Lochplatte ausgebildete Strahlzerlegeplatte 17, in deren quer zur Strömungsrichtung angeordneten Plattenebene eine Vielzahl gleichmäßig verteilter und hier runder Durchtrittsöffnungen 18 vorgesehen sind.The jet splitting device 9 of the jet regulator 80 according to FIG. 6 has a jet disassembly plate 17 designed as a perforated plate, in the plate plane arranged transversely to the direction of flow a large number of evenly distributed and round through openings 18 are provided.

Wenn beispielsweise bei derartigen Lochplattensystemen das zuströmende Wasser nicht ausreichend abgebremst wird, kann es vorteilhaft sein, wenn der Lochplatte 2 der Strahlreguliereinrichtung 1 vorzugsweise mehrere Strahlreguliersiebe 19 vorgeschaltet sind. So weist die Strahlreguliereinrichtung 1 der Strahlregler 30 und 40 gemäß Fig. 3 und 4 zwei voneinander und von der Lochplatte 2 beabstandete Strahlreguliersiebe 19 auf, die eine Vorregulierung und eine gleichmäßige Aufteilung der Einzelstrahlen bewirken.If, for example, in such perforated plate systems incoming water is not slowed down sufficiently, it can be advantageous if the perforated plate 2 of the jet regulating device 1 preferably a plurality of jet regulating screens 19 are connected upstream. For example, the jet regulating device 1 the jet regulator 30 and 40 according to FIGS. 3 and 4 two of each other and jet regulating screens 19 spaced from the perforated plate 2 on that a pre-regulation and an even division of individual rays.

Der Strahlregler 80 gemäß Fig. 6 stellt demgegenüber eine bevorzugte Ausführungsform dar. Hier hat die Strahlreguliereinrichtung 1 quer zur Durchströmrichtung verlaufende Stifte 21 oder Stege, welche der Lochplatte 2 der Strahlreguliereinrichtung 1 vorgeschaltet sind. Diese jeweils parallel zueinander angeordneten Stifte 21 sind rostartig in drei, quer zur Durchströmrichtung orientierten Ebenen nebeneinander angeordnet. Die Stifte 21 der drei Stiftlagen sind quer zur Strömungsrichtung seitlich versetzt angeordnet, wobei die Stifte 21 der jeweils stromabwärts angeordneten Stiftlage in dem durch die Stifte 21 einer stromaufwärts benachbarten Stiftlage gebildeten Strömungsweg angeordnet sind. Dabei ist der Abstand benachbarter Stifte 21 einer Stiftlage etwa gleich.In contrast, the jet regulator 80 according to FIG. 6 provides one preferred embodiment. Here, the jet regulating device 1 pins 21 running transversely to the flow direction or webs, which the perforated plate 2 of the jet regulating device 1 are connected upstream. These are parallel to each other Arranged pins 21 are rusty in three, transverse to Flow-oriented levels arranged side by side. The pins 21 of the three pin layers are transverse to the direction of flow laterally offset, the pins 21 of the each downstream pin position in the by the Pins 21 of an upstream adjacent pin layer are formed Flow path are arranged. The distance is closer Pins 21 a pin position about the same.

Die Stifte 21 weisen ein gerundetes, strömungsgünstiges Querschnittsprofil auf, wobei die Stifte 21 der beiden oberen Stiftlagen ein längliches Querschnittsprofil haben.The pins 21 have a rounded, streamlined Cross-sectional profile, with the pins 21 of the top two Pin positions have an elongated cross-sectional profile.

Wie aus Fig. 6 deutlich wird, sind die Stifte 21 der zuströmseitig ersten Stiftlage in Fluchtrichtung zu den Lochachsen der in der Strahlzerlegeplatte vorgesehenen Durchtrittsöffnungen 18 angeordnet. Die Durchtrittsöffnungen 18 in der Strahlzerlegeplatte 17 sind in Durchströmrichtung konisch verengend ausgebildet und weisen zuströmseitig einen Einlaufradius oder Einlaufkonus auf. Dabei können die ebenfalls zur Vorregulierung dienenden Stifte 21 mit dem Strahlreglergehäuse 5 einstückig verbunden und ebenfalls aus Kunststoff hergestellt sein. Der in Fig. 6 dargestellte Strahlregler 80 läßt sich somit aus nur einem Material herstellen und kann entsprechend einfach entsorgt und einer Wiederverwertung des Kunststoffmaterials zugeführt werden. Dabei neigt die aus den quer zur Strömungsrichtung orientierten Stiften 21 sowie aus der Lochplatte 2 bestehende Strahlreguliereinrichtung 1 des Strahlreglers 80 weniger zu einer Verkalkung, wie sie bei herkömmlichen Strahlreguliersieben vor allem in den Kreuzungspunkten der Gitternetzstruktur der einzelnen Siebe entsteht. Mit den quer zur Strömungsrichtung orientierten Stiften 21 sowie der Lochplatte 2 des Strahlreglers 80 läßt sich dennoch auch bei hohen Literleistungen eine ausreichende Strahlregulierung erreichen, um eine normgerechte Geräuschentwicklung zu gewährleisten.As is clear from Fig. 6, the pins 21 are the upstream first pin position in the direction of escape to the hole axes of the openings provided in the jet disassembly plate 18 arranged. The passage openings 18 in the jet disassembly plate 17 are conically narrowing in the flow direction trained and have an inlet radius or Inlet cone on. They can also be used for pre-regulation serving pins 21 with the jet regulator housing 5 in one piece connected and also be made of plastic. The The jet regulator 80 shown in FIG. 6 can thus only be made from a material and can be easily disposed of accordingly and fed to a recycling of the plastic material become. This tends to cross the direction of flow oriented pins 21 and consisting of the perforated plate 2 Jet regulator 1 of the jet regulator 80 less calcification, as is the case with conventional jet regulating screens especially in the intersections of the grid structure of the individual sieves are created. With the cross to the flow direction oriented pins 21 and the perforated plate 2 of the jet regulator 80 can still be a high liter output achieve sufficient jet regulation in order to achieve a To ensure noise development.

Bei den im Querschnitt runden Strahlreglern kann es vorteilhaft sein, wenn die auf der äußeren Ringzone angeordneten Durchflußlöcher 3 der Lochplatte 2 außenseitig zu einem kreisförmigen und das Lochfeld begrenzenden Hüllkreis verzerrt geformt sind. Dadurch werden unerwünschte Strömungshindernisse auch im Randbereich der Lochplatte 2 vermieden.In the case of the jet regulators which are round in cross section, it can be advantageous be when the flow holes arranged on the outer ring zone 3 of the perforated plate 2 on the outside to a circular and the enveloping circle delimiting the hole field are shaped in a distorted manner. This will also prevent undesirable flow obstacles in the Edge area of the perforated plate 2 avoided.

Wie die Fig. 1 bis 4 sowie 6 zeigen, weisen die dort dargestellten Strahlregler 10 bis 40 sowie 80 ein Vorsatzsieb 22 auf, das zuströmseitig vor der Strahlreguliereinrichtung 1 sowie der Strahlzerlegeeinrichtung 9 angeordnet ist. Dieses Vorsatzsieb 22 soll die im Wasser eventuell mitgeführten Schmutzpartikel ausfiltern und die Funktion der Strahlregler 10 bis 40 sowie 80 sichern.As shown in FIGS. 1 to 4 and 6, those shown there Aerators 10 to 40 and 80 on an additional screen 22, the upstream side in front of the jet regulating device 1 and the beam splitting device 9 is arranged. This front screen 22 should be the dirt particles that may be carried in the water filter and the function of the aerators 10 to 40 as well Secure 80.

Die hier dargestellten Strahlregler 10 bis 80 sind mit vergleichsweise geringem Aufwand herstellbar. Aufgrund der wabenzellenartig ausgebildeten Lochplatte 2 ihrer Strahlreguliereinrichtung 1 zeichnen sich die Strahlregler 10 bis 80 durch eine besonders gute Strahlformung und eine hohe Funktionssicherheit aus.The jet regulators 10 to 80 shown here are included comparatively easy to produce. Due to the perforated plate 2 of its jet regulating device, which is designed like a honeycomb cell 1 are characterized by the aerators 10 to 80 particularly good beam shaping and high functional reliability out.

Die hier dargestellten Strahlregler weisen einen runden Querschnitt auf. Möglich ist aber auch, solche Auslaufvorrichtungen mit einem ovalen oder dergleichen gerundeten, einem kreissegmentartigen oder einem eckigen Umriß herzustellen. Zusätzlich oder statt dessen kann zumindest ein wabenzellenartiges Lochfeld in der Lochplatte 2 vorgesehen sein, welches einen runden, gerundeten, kreissegmentartigen oder eckigen Umriß hat.The jet regulators shown here have a round one Cross section on. Such outlet devices are also possible with an oval or the like rounded, one to produce a segment of a circle or a square outline. In addition or instead, at least one honeycomb cell can be used Perforated field can be provided in the perforated plate 2, which a round, rounded, segment-like or angular outline Has.

So ist in Fig. 7 die als auslaufseitige Strahlreguliereinrichtung dienende Lochplatte 2 einer ansonsten nicht weiter dargestellten sanitären Auslaufvorrichtung gezeigt. Die Lochplatte 2 in Fig. 7 weist Durchflußlöcher 3 auf, die einen kreissegmentartigen lichten Durchflußquerschnitt haben. Die kreissegmentartigen Durchflußlöcher 3 sind auf mehreren konzentrischen Ringbereichen angeordnet. Dabei werden die gleichmäßig voneinander beabstandeten Durchflußlöcher 3 durch dünne Führungswandungen 4 getrennt, deren Wandstärke nur einen Bruchteil des lichten Lochdurchmessers eines von den Führungswandungen 4 begrenzten Durchflußloches 3 beträgt.7 is the outlet-side jet regulating device serving perforated plate 2 of an otherwise not shown sanitary outlet device shown. The perforated plate 2 in Fig. 7 has flow holes 3, which are a segment of a circle have a clear flow cross-section. The circle segment-like Flow holes 3 are on several concentric ring areas arranged. The are evenly spaced from each other Flow holes 3 through thin guide walls 4 separated, whose wall thickness is only a fraction of the inside Hole diameter of a limited by the guide walls 4 Flow hole 3 is.

In Fig. 8 ist die Lochplatte 2 einer sanitären Auslaufvorrichtung gezeigt, die hier einen langgestreckten gerundeten Umriß hat. Dabei wird das Lochfeld der Lochplatte 2 in Fig. 8 durch Durchflußlöcher 3 gebildet, die im Mittelbereich A der Lochplatte 2 einen rechteckigen Durchflußquerschnitt haben, während die in den halbkreisförmigen Endbereichen B und C der Lochplatte 2 vorgesehenen Durchflußlöcher einen kreissegmentartigen Durchflußquerschnitt haben. Mittels der in Fig. 8 dargestellten Auslaufvorrichtung kann ein breiter Wasserstrahl geformt werden, der über seine gesamte Strahlbreite homogen und perlend-weich ausgebildet ist.In Fig. 8 the perforated plate 2 is a sanitary outlet device shown here an elongated rounded Outline.
