Description

Die Erfindung betrifft einen Strahlregler mit einem hülsenförmigen Strahlreglergehäuse, das am Wasserauslauf einer sanitären Auslaufarmatur montierbar ist, und mit einem Dichtring aus elastischem Material, der einen rechteckigen Querschnitt mit etwa parallelen Längswänden hat und der gegenüber einer benachbarten Ringfläche am Wasserauslauf der Auslaufarmatur in axialer Richtung abdichtet.The invention relates to a jet regulator with a sleeve-shaped jet regulator housing which can be mounted on the water outlet of a sanitary outlet fitting, and with a sealing ring made of elastic material which has a rectangular cross section with approximately parallel longitudinal walls and which seals against an adjacent annular surface at the water outlet of the outlet fitting in the axial direction ,

Aus der FR 2 948 133 Al ist ein Strahlregler mit einem hülsenförmigen Strahlreglergehäuse vorbekannt, das am Wasserauslauf einer sanitären Auslaufarmatur montierbar ist. Um das Strahlreglergehäuse gegenüber einer benachbarten Ringfläche am Wasserauslauf der Auslaufarmatur in axialer Richtung abdichten zu können, ist ein Dichtring vorgesehen. Der Dichtring, der einen rechteckigen Querschnitt mit etwa parallelen Längswänden hat, ist zuströmseitig derart in das Strahlreglergehäuse eingesetzt, dass der Dichtring mit dem dem Strahlreglergehäuse zugewandten Teilbereich reibschlüssig am Gehäuseinnenumfang des Strahlreglergehäuses anliegt, während der dem Strahlreglergehäuse abgewandte Teilbereich des Dichtrings über das Strahlreglergehäuse vorsteht. Beim Transport oder bei der Montage des vorbekannten Strahlreglers besteht aber die Gefahr, dass der Dichtring unbeabsichtigt derart verformt wird, dass der Dichtring aus dem Strahlreglergehäuse fällt und verloren geht. Da mit dem Verlust des Dichtrings auch die übrigen Bestandteile des vorbekannten Strahlreglers ihren Halt im Strahlreglergehäuse verlieren, besteht die Gefahr, dass der vorbekannte Strahlregler in seine Bestandteile auseinanderfällt und insbesondere für den unkundigen Anwender kaum noch funktionsgerecht zusammengebaut werden kann.From the FR 2 948 133 A1 is a jet regulator with a sleeve-shaped jet regulator housing previously known, which is mounted on the water outlet of a sanitary outlet fitting. In order to seal the jet regulator housing in the axial direction with respect to an adjacent annular surface on the water outlet of the outlet fitting, a sealing ring is provided. The sealing ring, which has a rectangular cross section with approximately parallel longitudinal walls, is inserted on the inflow side into the jet regulator housing in such a way that the sealing ring frictionally engages the housing inner circumference of the jet regulator housing with the partial region facing the jet regulator housing, while the portion of the sealing ring remote from the jet regulator housing projects beyond the jet regulator housing. During transport or during assembly of the previously known jet regulator, however, there is the risk that the sealing ring will be unintentionally deformed in such a way that the sealing ring falls out of the jet regulator housing and is lost. Since with the loss of the sealing ring and the other components of the prior art jet regulator lose their hold in the jet regulator housing, there is a risk that the previously known jet regulator falls apart into its components and can hardly be assembled in particular functionally suitable for the ignorant user.

Aus der NL 110 837 C ist eine Schraubverbindung vorbekannt, die zum Zusammenbau von zwei Rohrabschnitten bestimmt ist. Diese Rohrabschnitte weisen dazu an ihren einander zugewandten Rohrenden miteinander korrespondierende Gewinde auf, so dass das ein Außengewinde tragende erste Rohrende in das im benachbarten zweiten Rohrende vorgesehene Innengewinde eingeschraubt werden kann. Um diese Schraubverbindung zu sichern, ist auf das an dem ersten Rohrende vorgesehene Außengewinde eine Kontermutter aufgeschraubt. Diese Kontermutter weist auf ihrer dem zweiten Rohrende zugewandten Stirnseite eine Einsenkung auf, die einen radial nach innen vorstehenden umlaufenden Hinterschnitt trägt. In diese Einsenkung ist ein Dichtring eingelegt, der außenumfangseitig einen Ringabsatz hat. Dieser Ringabsatz wird von dem Hinterschnitt derart hintergriffen, dass der Dichtring mit geringem axialen Spiel sicher an der Kontermutter gehalten ist. Da der Dichtring bei der vorbekannten Schraubverbindung eine komplexe Kontur hat, erfordert dessen Herstellung einen größeren Aufwand. Aufgrund seiner komplexen Kontur vermag der Dichtring nicht über seine gesamte Auflagefläche mit der gleichen Dichtwirkung abzudichten.From the NL 110 837 C a screw connection is already known, which is intended for the assembly of two pipe sections. For this purpose, these pipe sections have mutually corresponding threads on their mutually facing pipe ends, so that the first pipe end carrying an external thread can be screwed into the internal thread provided in the adjacent second pipe end. To secure this screw, a lock nut is screwed onto the male thread provided on the first pipe end. This counter nut has on its end facing the second pipe end a depression, which carries a radially inwardly projecting circumferential undercut. In this depression, a sealing ring is inserted, the outside circumference has a ring shoulder. This annular shoulder is engaged behind of the undercut such that the sealing ring is securely held with little axial play on the lock nut. Since the sealing ring has a complex contour in the known screw, its production requires a greater effort. Due to its complex contour, the sealing ring can not seal over its entire bearing surface with the same sealing effect.

Aus der EP 1 770 225 B1 ist ein Strahlregler vorbekannt, der am Wasserauslauf einer sanitären Auslaufarmatur einen homogenen, nicht-spritzenden und perlend-weichen Wasserstrahl formen soll. Der vorbekannte Strahlregler weist ein hülsenförmiges Strahlreglergehäuse auf, in dessen Gehäuseinnenraum strahlformende Funktionselemente vorgesehen sind. Dem vorbekannten Strahlregler ist ein hülsenförmiges Auslaufmundstück zugeordnet, in welches das Strahlreglergehäuse von der Zuströmseite aus bis zu einem Einsetzanschlag einsetzbar ist. Das Auslaufmundstück weist ein Innengewinde auf, das mit einem Außengewinde am Wasserauslauf der Auslaufarmatur zusammenwirkt. Der aus EP 1 770 225 B1 vorbekannte Strahlregler ist mit einem Dichtring aus elastischem Material im Auslaufmundstück gesichert, welcher Dichtring zwischen dem zulaufseitigen Stirnrandbereich des Strahlreglergehäuses und einer benachbarten Ringfläche am Wasserauslauf der Auslaufarmatur in axialer Richtung abdichten soll. Um den Dichtring unverlierbar im Auslaufmundstück zu halten, ist am Außenumfang des Dichtringes zumindest ein Haltevorsprung vorgesehen, der in das Innengewinde am Innenumfang des Auslaufmundstücks vorsteht. Der mit zumindest einem Haltevorsprung ausgestaltete Dichtring ist jedoch nur in Verbindung mit einem Auslaufmundstück vorteilhaft einsetzbar.From the EP 1 770 225 B1 is a jet regulator previously known to form a homogeneous, non-splashing and pearly-soft water jet at the water outlet of a sanitary outlet fitting. The previously known jet regulator has a sleeve-shaped jet regulator housing, in the housing interior of which jet-forming functional elements are provided. The prior art jet regulator is associated with a sleeve-shaped outlet mouthpiece, in which the jet regulator housing can be inserted from the inflow side to an insertion stop. The outlet mouthpiece points an internal thread, which cooperates with an external thread on the water outlet of the outlet fitting. The out EP 1 770 225 B1 Previously known aerator is secured with a sealing ring made of elastic material in the outlet nozzle, which sealing ring between the inlet-side end edge region of the jet regulator housing and an adjacent annular surface at the water outlet of the outlet fitting is to seal in the axial direction. In order to keep the sealing ring captive in the outlet mouthpiece, at least one retaining projection is provided on the outer circumference of the sealing ring, which protrudes into the internal thread on the inner circumference of the outlet mouthpiece. However, the configured with at least one retaining projection sealing ring is advantageously used only in conjunction with an outlet nozzle.

Man hat jedoch auch bereits Strahlregler geschaffen, die am Außenumfang ihres hülsenförmigen Strahlreglergehäuses ein Außengewinde tragen. Diese vorbekannten Strahlregler können mit dem an ihrem Strahlreglergehäuse vorgesehenen Außengewinde derart in ein Innengewinde am Wasserauslauf eingeschraubt werden, dass ein solcher Strahlregler mit dem abströmseitigen Stirnrand des Wasserauslaufs etwa bündig abschließt. Auf ein zusätzliches Auslaufmundstück sind diese ein Außengewinde tragenden Strahlregler nicht angewiesen. Bei solchen Strahlreglern kann der erforderliche Dichtring nur mit dem Risiko beigefügt werden, dass der Dichtring bei der Lagerung und dem Transport eventuell verloren geht.However, it has also already created jet regulator, which carry an external thread on the outer circumference of its sleeve-shaped jet regulator housing. These prior art jet regulators can be screwed with the measures provided on their jet regulator housing external thread in an internal thread on the water outlet, that such a jet regulator terminates approximately flush with the downstream end edge of the water outlet. On an additional outlet mouthpiece these external thread carrying aerator are not dependent. With such jet regulators, the required sealing ring can only be added with the risk that the sealing ring may be lost during storage and transport.

Es besteht daher insbesondere die Aufgabe, einen Strahlregler der eingangs erwähnten Art zu schaffen, der nicht nur in Verbindung mit einem Auslaufmundstück -, sondern auch in einer ein Außengewinde tragenden Ausführungsform gelagert, transportiert und selbst in einer beliebigen Montagesituation leicht montiert werden kann, ohne dass der unbeabsichtigte Verlust des erforderlichen Dichtrings zu befürchten wäre.There is therefore in particular the task of creating a jet regulator of the type mentioned above, not only in connection with an outlet mouthpiece - but also stored in an external thread bearing embodiment, transported and even in any mounting situation can be easily mounted without the unintentional loss of the required sealing ring to be feared.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere darin, dass am zulaufseitigen Stirnrandbereich des Strahlreglergehäuses innenumfangsseitig wenigstens eine Gehäuse-Hinterschneidung vorgesehen ist, die den in den Gehäuse-Innenraum des Strahlreglergehäuses eingesetzten Dichtring am Strahlreglergehäuse sichert, und dass die Gehäuse-Hinterschneidung sich dazu in das elastische Material des Dichtrings derart einformt, dass der Dichtring in axialer Richtung unverrückbar im Gehäuse-Innenraum gehalten ist.The achievement of this object is in the jet regulator of the type mentioned in particular that on the inlet side end edge region of the jet regulator housing inner peripheral side at least one housing undercut is provided which secures the seal used in the housing interior of the jet regulator housing on the jet regulator housing, and that the housing -Hinterschneidung this formed in the elastic material of the sealing ring such that the sealing ring is held immovably in the housing interior in the axial direction.

Bei dem erfindungsgemäßen Strahlregler ist am zulaufseitigen Stirnrandbereich seines Strahlreglergehäuses innenumfangsseitig eine Gehäuse-Hinterschneidung vorgesehen, die sich in das elastische Material des Dichtrings derart einformt, dass der Dichtring in axialer Richtung unverrückbar im Gehäuse-Innenraum gehalten ist. Da sich die Gehäuse-Hinterschneidung in das elastische Material des Dichtrings einformt, ist ein Ringflansch oder ein Ringabsatz nicht zusätzlich erforderlich. Der erfindungsgemäß verwendete Dichtring kann vielmehr einen rechteckigen Querschnitt mit etwa parallelen Längswänden aufweisen, so dass auf die Einbaulage des Dichtrings nicht geachtet werden muss. Diese Ausgestaltung des erfindungsgemäßen Strahlreglers begünstigt dessen maschinelle und entsprechend kostengünstige Montage. Da der Dichtring auf diese Weise stets sicher am Strahlreglergehäuse gehalten ist, ist ein unbeabsichtigtes Lösen und ein Verlust des Dichtringes selbst dann nicht zu befürchten, wenn der erfindungsgemäße strahlregler so ausgebildet ist, dass er ein zusätzliches Auslaufmundstück nicht benötigt.In the jet regulator according to the invention, a housing undercut is provided on the inlet-side end edge region of its jet regulator housing on the inner peripheral side, which is formed in the elastic material of the sealing ring such that the sealing ring is held immovably in the housing interior in the axial direction. Since the housing undercut is formed in the elastic material of the sealing ring, an annular flange or an annular shoulder is not additionally required. The sealing ring used according to the invention may rather have a rectangular cross-section with approximately parallel longitudinal walls, so that it is not necessary to pay attention to the installation position of the sealing ring. This embodiment of the jet regulator according to the invention favors its mechanical and correspondingly cost-effective installation. Since the sealing ring is always securely held in this way on the jet regulator housing, unintentional loosening and loss of the sealing ring is not to be feared even if the jet regulator according to the invention is designed so that it does not require an additional outlet nozzle.

Damit der Dichtring sicher und fest an der am zulaufseitigen Stirnrandbereich des Strahlreglergehäuses vorgesehenen Gehäuse-Hinterschneidung gehalten werden kann, ist es zweckmäßig, wenn der Dichtring an seinem Ring-Außenumfang abströmseitig einen Ringflansch oder Ringabsatz hat, der die Gehäuse-Hinterschneidung hintergreift.So that the sealing ring can be held securely and firmly on the housing undercut provided on the inflow-side end edge region of the jet regulator housing, it is expedient for the sealing ring to have an annular flange or annular shoulder on its outer circumference on the outer circumference, which engages behind the housing undercut.

Auch der erfindungsgemäße Strahlregler benötigt strahlformende Funktionselemente, um einen homogenen, nicht-spritzenden und gegebenenfalls perlend-weichen Wasserstrahl formen zu können. Diese strahlformenden Funktionselemente werden vorzugsweise als Einsetzteile hergestellt, die in den Gehäuse-Innenraum des Strahlreglergehäuses eingesetzt werden können. Um nun die in den Gehäuse-Innenraum des Strahlreglergehäuses eingesetzten Funktionselemente sicher im Strahlreglergehäuse halten zu können, ist vorgesehen, dass das zumindest eine, in den Gehäuse-Innenraum bis zu einem Einsetzanschlag einsetzbare Einsetzteil mittels dem Dichtring im Gehäuse-Innenraum gesichert ist.The jet regulator according to the invention also requires jet-forming functional elements in order to be able to form a homogeneous, non-spattering and, if appropriate, pearly-soft water jet. These beam-forming functional elements are preferably produced as insert parts, which can be inserted into the housing interior of the jet regulator housing. In order to be able to securely hold the functional elements inserted in the housing interior of the jet regulator housing in the jet regulator housing, it is provided that the at least one insertion part which can be inserted into the housing interior up to an insertion stop is secured by means of the sealing ring in the housing interior.

Bei einer konstruktiv besonders einfachen und leicht herstellbaren Ausführungsform ist das wenigstens eine Einsetzteil zwischen dem ihm zugeordneten Einsetzanschlag und dem Dichtring im Gehäuse-Innenraum gehalten.In a structurally particularly simple and easily producible embodiment, the at least one insert part is held between the assigned insertion stop and the sealing ring in the housing interior.

Um das durch den erfindungsgemäßen Strahlregler durchströmende Wasser gut und gleichmäßig formen zu können, ist es zweckmäßig, wenn das wenigstens eine Einsetzteil eine Loch-, Gitter- oder Netzstruktur aufweist.In order to be able to form the water flowing through the jet regulator according to the invention well and uniformly, it is expedient for the at least one insert part to have a hole, grid or network structure.

Eine Ausführungsform gemäß der Erfindung kann darin bestehen, dass der erfindungsgemäße Strahlregler, dessen Dichtring an einer Gehäuse-Hinterschneidung seines Strahlreglergehäuses gesichert ist, in ein Auslaufmundstück eingesetzt ist, das ein Gewinde trägt, welches mit einem Gegengewinde am Wasserauslauf der sanitären Auslaufarmatur montierbar ist. Eine bevorzugte Weiterbildung gemäß der Erfindung sieht demgegenüber jedoch vor, dass das Strahlreglergehäuse an seinem Gehäuse-Außenumfang ein Außengewinde trägt zum Einschrauben in ein im Wasserauslauf der Auslaufarmatur vorgesehenes Innengewinde. Auch bei einer solchen weiterbildenden Ausführungsform, die ein zusätzliches Auslaufmundstück nicht benötigt, ist der zur axialen Abdichtung benötigte Dichtring sicher und fest am Strahlreglergehäuse gesichert.An embodiment according to the invention may consist in that the jet regulator according to the invention, the sealing ring on a housing undercut its jet regulator housing is secured, is inserted into an outlet nozzle, which carries a thread which is mountable with a mating thread on the water outlet of the sanitary outlet fitting. A preferred development according to the invention, however, provides on the other hand, that the jet regulator housing carries on its housing outer periphery an external thread for screwing into a provided in the water outlet of the outlet fitting internal thread. Even with such a further embodiment that does not require an additional outlet nozzle, the sealing ring required for the axial sealing is securely and firmly secured to the jet regulator housing.

Weiterbildungen gemäß der Erfindung ergeben sich aus der Beschreibung in Verbindung mit den Zeichnungen. Nachstehend wir die Erfindung anhand bevorzugter Ausführungsbeispiele noch näher beschrieben.Further developments according to the invention will become apparent from the description in conjunction with the drawings. Below, we will describe the invention with reference to preferred embodiments in more detail.

Bevorzugt wird jedoch die hier dargestellte Strahlregler-Ausführung 1, bei der das Strahlreglergehäuse 2 an seinem Gehäuse-Außenumfang ein Außengewinde 3 aufweist, das in ein im Wasserauslauf der sanitären Auslaufarmatur vorgesehenes Innengewinde einschraubbar ist, vorzugsweise derart, dass die Auslaufstirnseite 4 des Strahlreglergehäuses 2 etwa mit dem auslaufseitigen Stirnrand des Wasserauslaufs abschließt.Preferably, however, the jet regulator embodiment 1 shown here, in which the jet regulator housing 2 at its outer circumference has an external thread 3, which is screwed into a provided in the water outlet of the sanitary outlet fitting internal thread, preferably such that the outlet end face 4 of the jet regulator housing 2 approximately concludes with the outlet-side end edge of the water outlet.

Die Strahlreglerausführung 1 weist einen Dichtring 5 aus elastischem Material auf, der gegenüber einer benachbarten Ringfläche am Wasserauslauf der Auslaufarmatur in axialer Richtung abdichtet. Dabei ist am zulaufseitigen Stirnrandbereich 6 des Strahlreglergehäuses innenumfangsseitig wenigstens eine Gehäuse-Hinterschneidung 7 vorgesehen, welche den in dem Gehäuse-Innenraum 8 des Strahlreglergehäuses 2 eingesetzten und vorzugsweise über die Zuströmseite des Strahlreglergehäuses 2 vorstehenden Dichtring 5 in seiner Lage am Strahlreglergehäuse 2 sichert.The jet regulator design 1 has a sealing ring 5 made of elastic material, which seals in the axial direction with respect to an adjacent annular surface at the water outlet of the outlet fitting. At the inlet-side end edge region 6 of the jet regulator housing, at least one housing undercut 7 is provided on the inner peripheral side, which uses the one inserted in the housing interior 8 of the jet regulator housing 2 and preferably via the inflow side of the Jet regulator housing 2 protruding sealing ring 5 secures in position on the jet regulator housing 2.

Da der Dichtring 5 am Strahlreglergehäuse 2 gesichert gehalten ist, wird ein unbeabsichtigter Verlust des Dichtrings 5 vermieden.Since the sealing ring 5 is held secured on the jet regulator housing 2, an accidental loss of the sealing ring 5 is avoided.

Aus den Fig. 1 und 2 wird deutlich, dass von der Zuströmseite des Strahlreglergehäuses 2 aus zumindest ein Einsetzteil 9 in den Gehäuse-Innenraum 8 einsetzbar ist, das eine Loch-, Gitter- oder Netzstruktur aufweisen kann. Soweit das zumindest eine Einsetzteil 9 eine Gitter- oder Netzstruktur aufweist, wird diese durch Scharen einander an Kreuzungsknoten kreuzender Stege gebildet. In den Fig. 1 und 2 ist erkennbar, dass der am Strahlreglergehäuse 2 sicher gehaltene Dichtring 5 auch das zumindest eine Einsetzteil 9 im Gehäuse-Innenraum 8 des Strahlreglergehäuses 2 sichert. Dabei ist das wenigstens eine Einsetzteil 9 zwischen einem ihm zugeordneten Einsetzanschlag 11 im Gehäuse-Innenraum 8 und dem Dichtring 5 gehalten. Der Dichtring 5 der Strahlreglerausführung 1 dichtet zwischen dem zulaufseitigen Stirnrandbereich 6 des Strahlreglergehäuses 2 und/oder der zuströmseitigen Stirnfläche 13 des Einsetzteils 9 einerseits und einer benachbarten Ringfläche am Wasserauslauf der Auslaufarmatur andererseits in axialer Richtung ab.From the Fig. 1 and 2 It is clear that from the inflow side of the jet regulator housing 2 from at least one insert part 9 is inserted into the housing interior 8, which may have a hole, grid or network structure. As far as the at least one insert part 9 has a grid or network structure, this is formed by flocks crossing each other at crossing nodes webs. In the Fig. 1 and 2 It can be seen that the sealing ring 5 held securely on the jet regulator housing 2 also secures the at least one insertion part 9 in the housing interior 8 of the jet regulator housing 2. In this case, the at least one insertion part 9 is held between an insertion stop 11 assigned to it in the housing interior 8 and the sealing ring 5. The sealing ring 5 of the jet regulator design 1 seals between the inflow-side end edge region 6 of the jet regulator housing 2 and / or the inflow-side end face 13 of the insertion part 9 on the one hand and an adjacent annular face on the water outlet of the outlet fitting on the other hand in the axial direction.

Der Dichtring 5 der in den Fig. 1 und 2 abgebildeten Strahlregler-Ausführung 1 weist einen rechteckigen Querschnitt mit etwa parallelen Längswänden auf. Dabei ist in der längs geschnittenen Teilansicht in Fig. 2 gut zu erkennen, dass sich die Gehäuse-Hinterschneidung 7 in das elastische Material des Dichtrings 5 derart einformt, dass dieser Dichtring 5 in axialer Richtung unverrückbar im Gehäuse-Innenraum 8 sicher gehalten ist und nur durch eine beispielsweise manuelle Deformation des Dichtrings 5 aus seiner gesicherten Position im Strahlreglergehäuse 2 gelöst werden kann.The sealing ring 5 in the Fig. 1 and 2 illustrated jet regulator embodiment 1 has a rectangular cross-section with approximately parallel longitudinal walls. It is in the longitudinal sectional view in Fig. 2 good to see that the housing undercut 7 in such a form in the elastic material of the sealing ring 5, that this sealing ring 5 in the axial direction immovable in Housing interior 8 is held securely and can be solved only by an example, manual deformation of the sealing ring 5 from its secure position in the jet regulator housing 2.
