Description

Strahlregler  aerator
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 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 seals against an adjacent annular surface at the water outlet of the outlet fitting in the axial direction.
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 hülsenförmigesFrom EP 1 770 225 B1 a jet regulator is already known, which is 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 previously known jet regulator is a sleeve-shaped
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 zulaufseifigen 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 Ver- bindung mit einem Auslaufmundstück vorteilhaft einsetzbar. Outlet mouthpiece assigned, in which the jet regulator housing is used from the inflow side to an insertion stop. The outlet nozzle has an internal thread which cooperates with an external thread at the water outlet of the outlet fitting. The previously known from EP 1 770 225 B1 jet regulator is secured with a sealing ring made of elastic material in the outlet nozzle, which sealing ring between the zulaufseifigen 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 sealing ring configured with at least one holding projection is only Bond with an outlet nozzle advantageously used.
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 such 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 a particular object to provide a jet regulator of the type mentioned, not only in connection with an outlet nozzle -, but also mounted in an external thread carrying embodiment, transported and can be easily mounted even in any mounting situation, without the unintentional loss of the required sealing ring would be to be feared.
Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere darin, dass am zulaufseifigen Stirnrandbereich des Strahlreglergehäuses innenumfangsseitig eine Gehäuse-Hinterschneidung vorgesehen ist, welche den in den Gehäuse- Innenraum des Strahlreglergehäuses eingesetzten und vorzugsweise über die Zu- strömseite des Strahlreglergehäuses vorstehenden Dichtring in axialer Richtung am Strahlreglergehäuse sichert. 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 on the inner peripheral side a housing undercut is provided, which is inserted into the housing interior of the jet regulator housing and preferably on the inflow side of the jet regulator housing Sealing ring in the axial direction on the jet regulator housing secures.
Bei dem erfindungsgemäßen Strahlregler ist am zulaufseitigen Stirnrandbereich seines Strahlreglergehäuses innenumfangsseitig eine Gehäuse-Hinterschneidung vorgesehen, welche den in den Gehäuse-Innenraum des Strahlreglergehäuses eingesetzten Dichtring in axialer Richtung am Strahlreglergehäuse sichert. 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 is on the inlet side End edge region of its jet regulator housing on the inner peripheral side, a housing undercut provided which secures the sealing ring inserted into the housing interior of the jet regulator housing in the axial direction at the jet regulator housing. 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 against 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 circumferential circumference which engages behind the housing undercut.
Eine bevorzugte Weiterbildung gemäß der Erfindung sieht jedoch vor, dass die Gehäuse-Hinterschneidung in das elastische Material des Dichtrings eingeformt ist. Da bei dieser weiterbildenden Ausführungsform sich die Gehäuse-Hinterschneidung in das elastische Material des Dichtrings einformt, ist bei dieser Ausführungsform ein Ringflansch oder ein Ringabsatz nicht zusätzlich erforderlich. A preferred development according to the invention, however, provides that the housing undercut is formed in the elastic material of the sealing ring. Since in this further embodiment, the housing undercut forms in the elastic material of the sealing ring, in this embodiment, an annular flange or an annular shoulder is not additionally required.
Die maschinelle und entsprechend kostengünstige Montage des erfindungsgemäßen Strahlreglers wird noch begünstigt, wenn der Dichtring einen rechteckigen Querschnitt mit etwa parallelen Längswänden hat, so dass auf die Einbaulage des Dichtrings nicht geachtet werden muss. The mechanical and correspondingly cost-effective installation of the jet regulator according to the invention is still favored if the sealing ring has a rectangular cross section with approximately parallel longitudinal walls, so that the installation position of the sealing ring does not have to be taken into account.
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 produce a homogeneous, non-splashing and if necessary, to form pearlescent 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 insertion stop assigned to it 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 is secured to a housing undercut its jet regulator housing, 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, which does not require an additional outlet nozzle, which is for axial sealing required sealing ring securely and firmly secured to the jet regulator housing.

Der Dichtring 5 der Strahlreglerausführungen 1 , 10 dichtet zwischen dem Zulaufseifigen 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. It is clear from FIGS. 1 to 4 that at least one insert part 9 can be inserted into the housing interior 8 from the inlet side of the jet regulator housing 2, which can 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. It can be seen in FIGS. 1 to 4 that the sealing ring 5 held securely on the jet regulator housing 2 also secures the at least one insert part 9 in the housing interior 8 of the jet regulator housing 2. In this case, the at least one insert 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 embodiments 1, 10 seals between the Zulaufseifigen end edge region 6 of the jet regulator housing 2 and / or the inflow-side end face 13 of the insert part 9 on the one hand and an adjacent annular surface on the water outlet of the outlet fitting in the axial direction.
Während die in den Fig. 3 und 4 gezeigte Strahlregler-Ausführung 10 einen Dichtring 5 hat, der an seinem Ring-Außenumfang abströmseitig einen Ringabsatz oder Ringflansch 12 hat, der die Gehäuse-Hinterschneidung 7 hintergreift, weist der Dichtring 5 der in den Fig. 1 und 2 abgebildeten Strahlregler-Ausführung 1 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 . While the jet regulator embodiment 10 shown in FIGS. 3 and 4 has a sealing ring 5, which at its outer circumference has a ring heel or annular flange 12 which engages behind the housing undercut 7, the sealing ring 5 of the in FIG. 1 and 2 illustrated jet regulator embodiment 1 a rectangular cross-section with approximately parallel longitudinal walls. It can be clearly seen in the longitudinal sectional view in Fig. 2 that the housing undercut 7 in the elastic material of the sealing ring 5 is formed such that this sealing ring 5 is held securely in the axial direction immovably in the housing interior 8 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.
