Das Strahlreglergehäuse des vorbekannten Strahlreglers ist als Mehrkomponenten-Spritzgussteil ausgebildet, um am Wasseraustrittsende der Strahlbegrenzungswandungen die weichelastische Kunststoffoberfläche anformen zu können.

Es besteht daher die Aufgabe, einen Strahlregler der eingangs erwähnten Art zu schaffen, zu dessen Herstellung auch bei kleineren Stückzahlen ein geringerer Aufwand erforderlich ist, ohne dass das Strahlbild des Strahlreglers beeinflussende Kriechströme zu befürchten sind.It is therefore an object to provide a jet regulator of the type mentioned, for its production, even with smaller quantities less effort is required without the spray pattern of the jet regulator influencing creepage currents are to be feared.
Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere in den Merkmale des geltenden Anspruchs 1.The inventive solution to this problem is in the jet regulator of the type mentioned in particular in the features of the current claim. 1
Der erfindungsgemäße Strahlregler weist ein Strahlreglergehäuse auf, das an seiner Auslaufstirnseite mehrere Durchstecklöcher hat. Der erfindungsgemäße Strahlregler weist auch ein separates Einlegeteil auf, das bis zur Auslaufstirnseite in den Gehäuse-Innenraum des Strahlreglergehäuses eingesetzt ist. Das Einlegeteil hat ein Bodenelement, an dem mehrere schlauchförmige Spraydüsen aus weichelastischem Material vorgesehen sind, die jeweils ein auslaufstirnseitiges Durchsteckloch des Strahlreglergehäuses durchsetzen und mit ihrem freien Spraydüsen-Endbereich über die Auslaufstirnseite des Strahlreglers vorstehen. Das Einlegeteil weist auch einen entgegen der Zuströmrichtung vorstehenden Umfangsrandbereich auf, der als ein an dem Gehäuseinnenumfang dicht anliegender Dichtrand ausgestaltet ist. Da das Einlegeteil mit seinem entgegen der Zuströmrichtung vorstehenden Umfangsrandbereich am Gehäuse-Innenumfang dicht anliegt, kann das durch den erfindungsgemäßen Strahlregler durchströmende Wasser allein durch die Spraydüsen austreten und unerwünschte Kriechströme zwischen dem Innenumfang des Strahlreglergehäuses einerseits und dem AuBenumfang des Einlegeteiles andererseits werden vermieden. Um das in den Gehäuse-Innenraum eingesetzte separate Einlegeteil in axialer Richtung des Strahlreglers sichern und im Gehäuse-Innenraum an der Auslaufstirnseite niederhalten zu können, ist ein in den Gehäuse-Innenraum ebenfalls eingesetztes und/oder in den Gehäuse-Innenraum vorstehendes Einsetzteil vorgesehen, zwischen dem und der Auslaufstirnseite das Einlegeteil in axialer Richtung lagegesichert ist. Bei dem erfindungsgemäßen Strahlregler müssen das Strahlreglergehäuse einerseits und die auslaufseitigen Spraydüsen andererseits nicht als Mehrkomponenten-Spritzgussteil in einer komplexen Spritzgussform hergestellt werden, vielmehr ist es auch möglich, die Bauteile des erfindungsgemäßen Strahlreglers getrennt voneinander in separaten und vergleichsweise einfachen Spritzgussformen herzustellen. Obwohl die separat hergestellten Bauteile des erfindungsgemäßen Strahlreglers lediglich leicht lösbar ineinander eingesetzt werden, ist das Einlegeteil mit seinem weichelastischen und zum Ablösen von Kalkablagerungen auch einer gegebenenfalls nicht unerheblichen manuellen Kraftbeaufschlagung ausgesetzten Spraydüsen derart lagegesichert im Gehäuse-Innenraum angeordnet, dass funktionsbeeinträchtigende Relativverschiebungen der zum erfindungsgemäßen Strahlregler zusammengesetzten Bauteile nicht zu befürchten sind.The jet regulator according to the invention has a jet regulator housing which has a plurality of through holes at its outlet end face. The jet regulator according to the invention also has a separate insert part, which extends to the outlet end side is inserted into the housing interior of the jet regulator housing. The insert has a bottom element to which a plurality of tubular spray nozzles made of soft elastic material are provided, each of which pass through an outlet end-side through-hole of the jet regulator housing and protrude with its free spray nozzle end region over the outlet end face of the jet regulator. The insert also has a counter to the inflow direction projecting peripheral edge portion which is configured as a tightly against the housing inner circumference sealing edge. Since the insert rests tightly with its counter to the inflow direction protruding peripheral edge portion on the housing inner circumference, the water flowing through the jet regulator according to the invention can escape alone through the spray nozzles and unwanted leakage currents between the inner circumference of the jet regulator housing on the one hand and the AuBenumfang of the insert part are avoided. In order to secure the inserted into the housing interior separate insert in the axial direction of the jet regulator and hold down in the housing interior at the outlet end, a in the housing interior also used and / or projecting into the housing interior insertion part is provided between the and the outlet end face the insert is secured in position in the axial direction. In the jet regulator according to the invention, the jet regulator housing on the one hand and the outlet-side spray nozzles on the other hand need not be produced as a multi-component injection molded part in a complex injection mold, but it is also possible to produce the components of the jet regulator according to the invention separately in separate and relatively simple injection molds. Although the separately manufactured components of the jet regulator according to the invention are only slightly releasable inserted into each other, the insert is with its soft elastic and arranged to remove lime deposits also a possibly not insignificant manual application of force exposed spray nozzles positionally secured in the housing interior, that functionally impairing Relativverschiebungen the composite to the jet regulator components according to the invention are not to be feared.

Somit muss erst die Rastverbindung zwischen dem zuströmseitigen Bauteil und dem Strahlreglergehäuse beziehungsweise dem Gehäuseteil des Strahlreglergehäuses gelöst werden, bevor das Einsetzteil und das vom Einsetzteil im Gehäuse-Innenraum in axialer Richtung gesicherte Einlegeteil entnommen werden können.Since the jet regulator according to the invention has an inflow-side component, which is releasably latched to the jet regulator housing or a housing part of the jet regulator housing, and since the insert part is in turn secured by the inflow-side component in the housing interior of the jet regulator housing, those located in the housing interior of the jet regulator housing Insert inserts are always safely and securely housed there. Thus, only the latching connection between the inflow-side component and the jet regulator housing or the housing part of the jet regulator housing must be solved before the insert and the insert part secured in the housing interior in the axial direction can be removed.
Vorteilhaft ist es, wenn das Bodenelement des Einlegeteils platten- oder scheibenförmig ausgestaltet ist.It is advantageous if the bottom element of the insert is designed plate-shaped or disc-shaped.
Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass das Einlegeteil einen topfförmigen Teilbereich hat, und dass das Bodenelement des Einlegeteiles den Topfboden bildet. Bei dieser Ausführungsform weist das Einlegeteil einen topfförmigen Teilbereich auf, der sich auch in radialer Richtung lagegerecht in das Strahlreglergehäuse einsetzen lässt. Dabei bildet der Topfboden des topfförmigen Teilbereiches das im Gehäuse-Innenraum an der Auslaufstirnseite anliegende Bodenelement, an dem die schlauchförmigen Spraydüsen vorgesehen sind.A preferred embodiment according to the invention provides that the insert has a cup-shaped portion, and that the bottom element of the insert forms the bottom of the pot.

In den
Den Strahlreglern 1, 5, 30 und 31 ist ein separates Einlegeteil 6 zugeordnet, das in den Gehäuse-Innenraum bis zur Auslaufstirnseite 3 eingesetzt ist. Das Einlegeteil 6 hat mehrere schlauchförmige Spraydüsen 7, die zur Erzeugung einer Mehrzahl von vorzugsweise sichtbar getrennt austretender Einzelstrahlen bestimmt sind. Die Spraydüsen 7 durchsetzen jeweils ein auslaufstirnseitiges Durchsteckloch 4 des Strahlreglergehäuses 2 und stehen mit ihrem freien Spraydüsen-Endbereich über die Auslaufstirnseite 3 des Strahlreglers 1, 5, 30, 31 vor.The jet regulators 1, 5, 30 and 31, a separate insert 6 is assigned, which is inserted into the housing interior to the outlet end face 3. The insert 6 has a plurality of tubular spray nozzles 7, which are intended to produce a plurality of preferably visible separately separated exiting single jets. The spray nozzles 7 respectively pass through an outlet-end through-hole 4 of the jet regulator housing 2 and protrude beyond the outlet end face 3 of the jet regulator 1, 5, 30, 31 with their free spray nozzle end region.
Die vorbekannten Strahlregler 1, 5, 30, 31 weisen auch ein in den Gehäuse-Innenraum eingesetztes Einsetzteil 8 auf, zwischen dem und der Auslaufstirnseite 3 das Einlegeteil 6 in axialer Richtung lagegesichert ist.The previously known jet regulators 1, 5, 30, 31 also have an inserted into the housing interior insertion part 8, between which and the outlet end face 3, the insert 6 is secured in position in the axial direction.
Bei den hier dargestellten Strahlreglern 1, 5, 30, 31 müssen das Strahlreglergehäuse 2 einerseits und die auslaufseitigen Spraydüsen 7 andererseits nicht als Mehrkomponenten-Spritzgussteil in einer komplexen Spritzgussform hergestellt werden, - vielmehr ist es auch möglich, diese Bauteile getrennt voneinander in separaten und vergleichsweise einfachen Spritzgussformen herzustellen. Obwohl die separat hergestellten Bauteile 2, 7 der Strahlregler 1, 5, 30, 31 lediglich leicht lösbar ineinander eingesetzt werden, ist das Einlegeteil 6 mit seinem weichelastischen und zum Ablösen von Kalkablagerungen auch einer gegebenenfalls nicht unerheblichen manuellen Kraftbeaufschlagung ausgesetzten Spraydüsen 7 derart lagegesichert im Gehäuse-Innenraum angeordnet, dass funktionsbeeinträchtigende Relativverschiebungen der zu den Strahlreglern 1, 5, 30, 31 zusammengesetzten Bauteile nicht zu befürchten sind.In the jet regulators 1, 5, 30, 31 shown here, the jet regulator housing 2 on the one hand and the outlet side spray nozzles 7 on the other hand not be made as a multi-component injection molded part in a complex injection mold, - but it is also possible, these components separately from each other in separate and comparatively produce simple injection molds. Although the separately manufactured components 2, 7 of the jet regulators 1, 5, 30, 31 are only slightly detachable inserted into each other, the insert 6 is so secure in position in the housing with its soft elastic and for the removal of calcium deposits also a possibly not insignificant manual application of force exposed spray nozzles Interior arranged that functionally impairing relative shifts the components to the beam regulators 1, 5, 30, 31 are not to be feared.
Aus den Längsschnitten in den
Das hier topfförmige Einlegeteil 6 der Strahlregler 1, 5, 30, 31 hat einen entgegen der Zuströmrichtung vorstehenden Umfangsrandbereich 10, der als ein an dem Gehäuse-Innenumfang dicht anliegender Dichtrand ausgestaltet ist. Der entgegen der Zuströmrichtung vorstehende Umfangsrandbereich 10 ist dazu derart schräg nach außen orientiert, dass dieser Umfangsrandbereich praktisch eine an dem Gehäuseinnenumfang des Strahlreglergehäuses 2 dicht anliegende Lippendichtung bildet. Da der Umfangsrandbereich 10 des Einlegeteils 6 dicht am Innenumfang des Strahlreglergehäuses 2 anliegt, werden unerwünschte Kriechströme zwischen dem Einlegeteil 6 und dem Innenumfang des Strahlreglergehäuses 2 vermieden.The cup-shaped insert 6 of the jet regulators 1, 5, 30, 31 has a circumferential edge region 10 which protrudes counter to the inflow direction and which is configured as a sealing edge which tightly adjoins the housing inner circumference. The peripheral edge region 10 projecting counter to the inflow direction is oriented obliquely outwards in such a way that this peripheral edge region practically forms a lip seal tightly fitting against the housing inner circumference of the jet regulator housing 2. Since the peripheral edge portion 10 of the insert 6 abuts tightly against the inner periphery of the jet regulator housing 2, unwanted leakage currents between the insert 6 and the inner periphery of the jet regulator housing 2 are avoided.
Aus den perspektivischen Unteransichten in
Den Strahlreglern 1, 5, 30, 31 ist jeweils ein Durchflussmengenregler 12 vorgeschaltet, der die maximale Durchflussleistung pro Zeiteinheit auf einen druckunabhängigen Maximalwert begrenzt. Der Durchflussmengenregler 12 ist auf der Zuströmseite der Strahlregler 1, 5, 30, 31 mit diesen verrastbar oder dergleichen lösbar verbunden. Damit die Funktion der Durchflussmengenregler 12 und der ihnen abströmseitig nachgeschalteten Strahlregler 1, 5, 30, 31 nicht durch im Wasser eventuell mitgeführte Schmutzpartikel beeinträchtigt werden kann, ist den Durchflussmengenreglern 12 und den Strahlreglern 1, 5, 30, 31 jeweils ein Vorsatzsieb 13 vorgeschaltet, das mit dem Durchflussmengenregler 12 und dem betreffenden Strahlregler 1, 5, 30, 31 ebenfalls lösbar verbunden ist.The jet regulators 1, 5, 30, 31 are each preceded by a flow rate regulator 12, which controls the maximum flow rate limited per unit of time to a pressure-independent maximum value. The flow rate regulator 12 is on the upstream side of the jet regulator 1, 5, 30, 31 releasably connected to these or the like. Thus, the function of the flow rate regulator 12 and downstream of them downstream jet regulator 1, 5, 30, 31 can not be affected by possibly entrained in the water dirt particles, the flow rate controllers 12 and the beam regulators 1, 5, 30, 31 each preceded by a screen 13, which is also releasably connected to the flow regulator 12 and the respective jet regulator 1, 5, 30, 31.

For this purpose, the jet regulators 1, 5 have at their jet regulator housing 2 an annular flange or annular shoulder 32 with which the jet regulator 1, 5 rests on an annular shoulder, which is provided on the inside in the outlet mouthpiece.
Auch der Strahlregler 30 weist an dem Gehäuse-Außenumfang seines Strahlreglergehäuses 2 einen Ringflansch oder Ringabsatz 32 auf. Der Strahlregler 30 ist von der Zuströmseite eines Zwischenhalters 36 aus in diesen einsetzbar, bis sein Ringflansch oder Ringabsatz 32 auf einem am Innenumfang des hülsenförmigen Zwischenhalters vorgesehenen Ringabsatz oder dem zuströmseitigen Stirnrand des Zwischenhalters 36 aufliegt.

Der hülsenförmige Zwischenhalter 36 weist dazu an seinem Außenumfang ein Außengewinde 37 auf, mit dem der Zwischenhalter 36 in ein Innengewinde am Wasserauslauf einer sanitären Auslaufarmatur lösbar eingeschraubt werden kann.The jet regulator 30 also has an annular flange or annular shoulder 32 on the housing outer circumference of its jet regulator housing 2. The jet regulator 30 can be inserted from the upstream side of an intermediate holder 36 until its annular flange or annular shoulder 32 rests on an annular shoulder provided on the inner circumference of the sleeve-shaped intermediate holder or on the inflow-side end edge of the intermediate holder 36. The jet regulator 30 can be secured by means of the intermediate holder 36 in the water outlet of a sanitary outlet fitting. The sleeve-shaped intermediate holder 36 has to its outer periphery an external thread 37, with which the intermediate holder 36 can be detachably screwed into an internal thread on the water outlet of a sanitary outlet fitting.
