Description

Die Erfindung betrifft einen Strahlregler mit einem, in eine sanitäre Auslaufarmatur einsetzbaren Strahlreglergehäuse, mit einem zuströmseitigen Bauteil, das sich über den lichten Auslaufquerschnitt erstreckt, und mit einem am Strahlreglergehäuse umlaufenden Dichtprofil, das zwischen dem Strahlreglergehäuse einerseits und der Auslaufarmatur andererseits abdichtet und wenigstens zwei ringförmig umlaufende Dichtlippen hat, wobei das zuströmseitige Bauteil mit dem Dichtprofil einstückig verbunden ist.The invention relates to a jet regulator with a usable in a sanitary outlet fitting jet regulator housing, with an inflow-side member which extends over the clear outlet cross-section, and with a rotating on the jet body seal profile sealing between the jet regulator housing on the one hand and the outlet fitting on the other hand and at least two annular has circumferential sealing lips, wherein the inflow-side member is integrally connected to the sealing profile.

Strahlregler sind bereits in verschiedenen Ausführungen bekannt. Solche Strahlregler werden regelmäßig in ein Auslaufmundstück eingesetzt, das an einer sanitären Auslaufarmatur lösbar gehalten ist. Mit Hilfe solcher Strahlregler soll ein homogener, weicher und nichtspritzender Wasserstrahl geformt werden.Jet regulators are already known in various designs. Such jet regulators are regularly used in an outlet nozzle, which is detachably held on a sanitary outlet fitting. With the help of such jet regulator to a homogeneous, soft and non-squirting water jet to be formed.

Die bei diesen Strahlreglern verwendete Dichtung ist üblicherweise ein separater Dichtring aus Gummi oder einem ähnlich flexiblen Material, der zwischen Strahlreglergehäuse und Auslaufarmatur eingesetzt wird. Beim Befestigen des Strahlreglers an der Auslaufarmatur wird der Dichtring zusammengedrückt und dichtet so den Zwischenraum zwischen Strahlreglergehäuse und Auslaufarmatur ab. Nachteilig ist hierbei, dass der Dichtring als relativ kleines Bauteil leicht verloren gehen kann und dass das Einsetzen des Strahlreglers mit oben aufgelegtem Dichtring, ohne dass der Dichtring dabei seine optimale Position verlässt, schwierig ist und handwerkliches Geschick erfordert.The seal used in these jet regulators is usually a separate sealing ring made of rubber or a similar flexible material, which is used between the jet regulator housing and outlet fitting. When attaching the jet regulator to the outlet fitting, the sealing ring is compressed, thus sealing the gap between the jet regulator housing and the outlet fitting. The disadvantage here is that the sealing ring can be easily lost as a relatively small component and that the insertion of the jet regulator with top-mounted sealing ring, without the sealing ring leaves its optimal position, difficult is and requires manual skill.

Man hat daher auch bereits einen belüfteten Strahlregler der eingangs erwähnten Art mit einem Strahlreglergehäuse geschaffen, das in eine sanitäre Auslaufarmatur einsetzbar ist, wobei der vorbekannte Strahlregler eine Strahlzerlegeeinrichtung hat, die von der Zuströmseite aus in das Strahlreglergehäuse montiert werden kann vgl: FR-A- 2 039 712 . Die Strahlzerlegeeinrichtung weist zwei Lochplatten auf, deren Durchflusslöcher versetzt zueinander angeordnet sind. Dabei deckt die zuströmseitige Lochplatte der Strahlzerlegeeinrichtung das Strahlreglergehäuse stirnseitig ab. Auf der Zuströmseite dieser Lochplatte ist ein umlaufendes Dichtprofil einstückig angeformt, das zwischen dem Strahlreglergehäuse einerseits und der Auslaufarmatur andererseits abdichtet. Dieses Dichtprofil weist zwei ringförmig umlaufende Dichtlippen auf, die die gleiche Höhe aufweisen und den Stirnrandbereich der sanitären Auslaufarmatur beaufschlagen.It has therefore also already created a vented jet regulator of the type mentioned with a jet regulator housing, which is used in a sanitary outlet fitting, the prior art jet regulator has a jet disintegrating device, which can be mounted from the inflow side in the jet regulator housing see: FR-A-2 039 712 , The jet disintegrating device has two perforated plates, whose flow holes are offset from one another. The inflow-side perforated plate of the jet disassembling device covers the jet regulator housing at the end. On the upstream side of this perforated plate, a circumferential sealing profile is integrally formed, which seals between the jet regulator housing on the one hand and the outlet fitting on the other. This sealing profile has two annular circumferential sealing lips, which have the same height and act on the end edge region of the sanitary outlet fitting.

Vergleichbare Strahlregler sind auch aus der US-A- 3 851 825 und der US-A- 3 672 574 bekannt, wobei diese Strahlregler jedoch ein zuströmseitiges Bauteil aufweisen, an das ein zwischen Strahlregler einerseits und Auslaufarmatur andererseits abdichtendes Dichtprofil mit allerdings nur einer ringförmig umlaufenden Dichtlippe einstückig angeformt ist.Comparable jet regulators are also from the US-A-3,851,825 and the US-A-3,672,574 However, these jet regulators have a component on the inflow side, to which a sealing profile sealing between the jet regulator, on the one hand, and the outlet fitting, on the other hand, is integrally formed with, however, only one annular circumferential sealing lip.

Es besteht die Aufgabe, einen aus einer reduzierten Anzahl von Bauteilen herstellbaren Strahlregler zu schaffen, mit dem sich Kriech- und Leckströme der den Strahlregler durchströmenden Flüssigkeit dauerhaft verhindern lassen.It is the object to provide a producible from a reduced number of components jet regulator, with the creepage and leakage currents of the jet flowing through the liquid can be permanently prevented.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, dass die Dichtlippen unterschiedliche Höhen aufweisen und mit zunehmendem, auf den Strahlregler einwirkenden Einsetzdruck nacheinander wirksam werden.The achievement of this object is that the sealing lips have different heights and with increasing, acting on the jet regulator insertion pressure successively effective.

Die bei dem erfindungsgemäßen Strahlregler vorgesehene abgestufte Ausgestaltung des Dichtprofils kann bewirken, dass bei Ausfall einer Dichtlippe die benachbarten Dichtlippen des Dichtprofils wirksam werden. Außerdem kann durch Nachziehen des an der Auslaufarmatur verschraubten Auslaufmundstückes auf den Strahlregler ein Einsetzdruck ausgeübt werden, derart, dass zumindest auch weitere Dichtungen des Dichtprofils wirksam werden können. So ist es nach längerem Gebrauch des erfindungsgemäßen Strahlreglers dadurch möglich, die Dichtwirkung durch Nachziehen des an der Auslaufarmatur verschraubten Auslaufmundstückes langzeitig aufrecht zu erhalten. Ist die höchste Dichtlippe bereits etwas beschädigt oder abgenutzt oder unflexibel geworden, kann die in der Höhe nächstkommende Dichtlippe die Dichtwirkung nach dem Festziehen wieder erreichen. Außerdem können eventuelle kleine Unebenheiten des Gegenanschlags der Auslaufarmatur ausgeglichen werden. Das zuströmseitige Bauteil mit dem daran einstückig verbundenen Dichtprofil erstreckt sich dabei als einziges Bauteil über den lichten Querschnitt und verhindert dadurch Kriech- und Leckströme der den Strahlregler durchströmenden Flüssigkeit zwischen dem Strahlreglergehäuse und der Auslaufarmatur sowie zwischen dem Strahlreglergehäuse und den Einsetzteilen des Strahlreglers.The provided in the jet regulator according to the invention graduated configuration of the sealing profile can cause the failure of a sealing lip, the adjacent sealing lips of the sealing profile are effective. In addition, an insertion pressure can be exerted on the jet regulator by tightening the outlet nozzle bolted to the outlet fitting, such that at least further seals of the sealing profile can be effective. Thus, it is possible after prolonged use of the jet regulator according to the invention, the long-term to maintain the sealing effect by tightening the screwed on the outlet fitting outlet nozzle. If the highest sealing lip has already become slightly damaged or worn or inflexible, the sealing lip closest to the height can reach the sealing effect again after tightening. In addition, any small bumps of the counter-attack of the outlet fitting can be compensated. The inflow-side component with the sealing profile integrally connected thereto extends as a single component over the clear cross section and thereby prevents creepage and leakage currents flowing through the jet regulator fluid between the jet regulator housing and the outlet fitting and between the jet regulator housing and the insert parts of the jet regulator.

Die Dichtlippen am Dichtprofil des erfindungsgemäßen Strahlreglers können entweder elastisch und flexibel ausgestaltet sein und sich dadurch beim Befestigen des Strahlreglers im Auslaufmundstück an der Auslaufarmatur dem Gegenanschlag anpassen, oder die Dichtlippen sind so gestaltet, dass eine Verformung nur schwer möglich ist, so dass die Dichtlippen beim Befestigen nur durch eine Flächenpressung durch den Gegenanschlag der Auslaufarmatur abdichten. Diese beiden Möglichkeiten können mit mehreren Dichtlippen auf unterschiedliche Weise kombiniert werden.The sealing lips on the sealing profile of the jet regulator according to the invention can be designed either elastic and flexible and thereby when mounting the Adjust the jet regulator in the outlet nozzle to the outlet fitting of the counter-stop, or the sealing lips are designed so that deformation is difficult, so that the sealing lips seal during mounting only by a surface pressure through the counter-stop of the outlet fitting. These two possibilities can be combined with several sealing lips in different ways.

Dabei ist es vorteilhaft, wenn das zuströmseitige Bauteil ein Gehäuseteil mit angeformter Strahlzerlegeeinrichtung ist. Da die Strahlzerlegeeinrichtung einstückig an das zuströmseitige Gehäuseteil angeformt ist, wird eine separat einsetzbare Strahlzerlegeeinrichtung vermieden. Außerdem ist die an das Gehäuseteil angeformte Strahlzerlegeeinrichtung wesentlich stabiler und neigt weniger zu lärmverursachenden Eigenschwingungen wie dies bei bisher bekannten Strahlreglern der Fall ist. Durch die an das zuströmseitige Bauteil einstückig angeformte Strahlzerlegereinrichtung sowie das ebenfalls daran einstückig verbundene Dichtprofil kann eine bessere Toleranzhaltigkeit des gesamten Strahlreglers erreicht werden, da eine geringere Maßaddition von Toleranzen von Einzelteilen stattfindet.It is advantageous if the inflow-side component is a housing part with integrally formed jet decomposing device. Since the jet disintegrating device is integrally formed on the inflow-side housing part, a separately usable jet disintegrating device is avoided. In addition, the integrally formed on the housing part beam decomposer is much more stable and less prone to noise-causing natural oscillations as is the case with previously known beam regulators. By integrally formed on the inflow-side component beam splitter and also integrally connected thereto sealing profile better tolerance of the entire beam regulator can be achieved, since a smaller Maßaddition of tolerances of individual parts takes place.

Vorteilhaft kann es sein, wenn der zuströmseitige Stirnrandbereich des Gehäuseteils als das Dichtprofil ausgestaltet ist. Ein derart ausgeführtes Strahlreglergehäuse kann auch mit einem vergleichsweise breiten Stirnrand ausgestaltet sein, ohne dass der lichte äußere Querschnitt dadurch zu sehr eingeschränkt wird. Dieser vergleichsweise breite Stirnrand am Strahlreglergehäuse kann anschließend sehr gut zur Ausgestaltung auch eines vergleichsweise komplexen Dichtprofils herangezogen werden.It may be advantageous if the inflow-side end edge region of the housing part is designed as the sealing profile. A jet regulator housing designed in this way can also be designed with a comparatively wide front edge, without the clear outer cross section being thereby restricted too much. This comparatively wide end edge on the jet regulator housing can then be used very well for the design of a comparatively complex sealing profile.

Bei der Ausführung des Dichtprofils ist es zweckmäßig, wenn das Dichtprofil zumindest eine Flächen- und/oder eine Lippendichtung aufweist. Diese Formen des Dichtprofils können zusammen mit dem Gegenanschlag der Auslaufarmatur eine wirksame Abdichtung bewirken, wenn das Dichtprofil den Gegenanschlag beaufschlagt und dabei eine Linien- und/oder Flächenpressung auf das Dichtprofil ausgeübt wird.In the execution of the sealing profile, it is expedient if the sealing profile has at least one surface and / or a lip seal. These forms of the sealing profile can effect an effective seal together with the counter-stop of the outlet fitting, when the sealing profile acts on the counter-stop and thereby a line and / or surface pressure is exerted on the sealing profile.

Um eine übermäßige Verformung des Dichtprofils zu verhindern, ist es zweckmäßig, wenn das zuströmseitige Bauteil einen Einsetz-Anschlag aufweist, der in Gebrauchsstellung des Strahlreglers eine Verformung des Dichtprofils begrenzt. Anderenfalls könnte das Dichtprofil beschädigt oder übermäßig verformt werden, was zu einer Undichtigkeit im Bereich zwischen Strahlreglergehäuse und Auslaufarmatur und somit zu entsprechenden Kriechströmen führen könnte.In order to prevent excessive deformation of the sealing profile, it is expedient if the inflow-side component has an insertion stop which limits a deformation of the sealing profile in the position of use of the jet regulator. Otherwise, the sealing profile could be damaged or excessively deformed, which could lead to a leak in the area between the jet regulator housing and the outlet fitting and thus to corresponding leakage currents.

Bei der Gestaltung des Dichtprofils ist es vorteilhaft, wenn das Dichtprofil zumindest eine Dichtung mit einer Dichtprofilbasis hat, die als Einsetz-Anschlag ausgestaltet ist. Das Dichtprofil kann dabei auf der oberen Begrenzungsfläche der Dichtprofilbasis angeordnet sein. Der Einsetz-Anschlag kann dazu dienen, beim Befestigen des Strahlreglers an der Armatur beispielsweise über eine Schraubverbindung die Einschraubtiefe zu begrenzen. Geschieht das Einschrauben ohne Werkzeuge manuell, so-kann der Einsetz-Anschlag ein Festigkeitsgefühl der Schraubverbindung vermitteln, indem die Beaufschlagung des Gegenanschlags an der Armatur durch den Einsetz-Anschlag spürbar ist.In the design of the sealing profile, it is advantageous if the sealing profile has at least one seal with a sealing profile base, which is designed as an insertion stop. The sealing profile can be arranged on the upper boundary surface of the sealing profile base. The insertion stop can serve to limit the screwing depth when attaching the jet regulator to the valve, for example via a screw connection. If screwing is done manually without tools, the insertion stop can give a feeling of firmness of the screw connection by the action of the insertion stop on the fitting being felt.

Um eine möglichst große Fläche des lichten Querschnitts des Strahlreglers nutzen zu können beziehungsweise seinen lichten Querschnitt nicht unnötig zu verengen, ist es zweckmäßig, wenn das Dichtprofil und gegebenenfalls sein Einsetz-Anschlag mit einem den lichten Querschnitt begrenzenden Stirnrandbereich der Auslaufarmatur zusammenwirkt, der dem Strahlreglergehäuse gleichzeitig als Gegenanschlag dient.In order to use the largest possible area of the clear cross-section of the jet regulator or its clear Not to narrow cross-section unnecessarily, it is useful if the sealing profile and possibly its insertion stop cooperates with a clear cross-section limiting end edge region of the outlet fitting, which serves the jet regulator housing simultaneously as a counter-stop.

Dabei ist es für die Funktion des Einsetz-Anschlags besonders vorteilhaft, wenn der Einsetz-Anschlag dem Dichtprofil in radialer Richtung benachbart angeordnet ist. Somit kann der Einsetz-Anschlag genau die Kräfte auffangen, die das Dichtprofil eventuell beschädigen könnten. Außerdem kann damit auf dem lichten Querschnitt des Strahlreglers eine platzsparende Anordnung des Einsetz-Anschlags und des Dichtprofils erreicht werden.It is particularly advantageous for the function of the insertion stop when the insertion stop is arranged adjacent to the sealing profile in the radial direction. Thus, the insertion stop can accurately absorb the forces that could possibly damage the sealing profile. In addition, a space-saving arrangement of the insertion stop and the sealing profile can thus be achieved on the clear cross section of the jet regulator.

Dabei kann es vorteilhaft sein, wenn die Dichtlippen gestufte Höhen aufweisen und wenn die höchste Dichtlippe die innerste oder äußerste Dichtung des Dichtprofils bildet.It may be advantageous if the sealing lips have stepped heights and if the highest sealing lip forms the innermost or outermost seal of the sealing profile.

Möglich ist es, dass zumindest das zuströmseitige Bauteil als Mehrkomponenten-Spritzgussteil hergestellt ist, und dass das Bauteil im Bereich der wenigstens einen Dichtung aus einem flexiblen und/oder elastischen Material besteht. Für das einfache Recycling der den Strahlregler bildenden Materialien ist es jedoch zweckmäßig, wenn das zuströmseitige Bauteil und zumindest das damit einstückig verbundene Dichtprofil aus demselben, vorzugsweise lebensmittelechten Material hergestellt sind. Dadurch können der Herstellungsaufwand vereinfacht und die Werkzeugkosten für ein eventuell erforderliches Spritzgusswerkzeug vergleichsweise gering gehalten werden.It is possible that at least the inflow-side component is produced as a multi-component injection-molded part, and that the component in the region of the at least one seal consists of a flexible and / or elastic material. For the simple recycling of the jet regulator forming materials, however, it is expedient if the inflow-side component and at least the sealing profile integrally connected therewith are made of the same, preferably food grade, material. As a result, the production costs can be simplified and the tool costs for a possibly required injection molding tool can be kept comparatively low.

Below is the invention with its essential. Parts explained in more detail with reference to the drawing. It shows in partly schematized representation:

Fig. 2
a partially sectioned view of a jet regulator with two radially adjacent sealing lips with chamfers in the same direction and
Fig. 3
a partially sectioned view of a jet regulator with four radially adjacent, annular circumferential sealing lips.

In den Fig. 1 bis 3 ist jeweils ein im Ganzen mit 1 bezeichneter Strahlregler dargestellt. Der Strahlregler 1 weist ein am Strahlreglergehäuse 2 umlaufendes Dichtprofil 6 auf, das zwischen dem Strahlreglergehäuse 2 einerseits und der Auslaufarmatur andererseits abdichtet, wobei das Dichtprofil 6 mit einem zuströmseitigen Bauteil, das sich über den lichten Auslaufquerschnitt des Strahlreglers 1 erstreckt, einstückig verbunden ist.In the Fig. 1 to 3 in each case a designated as a whole with 1 jet regulator is shown. The jet regulator 1 has a sealing profile 6 running around the jet regulator housing 2, which seals between the jet regulator housing 2 on the one hand and the outlet fitting on the other hand, wherein the sealing profile 6 is integrally connected to an inflow-side component which extends over the clear outlet cross section of the jet regulator 1.

Möglich ist, dass das Strahlreglergehäuse einteilig ausgestaltet ist. In den Fig. 1 bis 3 jedoch ist erkennbar, dass das Strahlreglergehäuse 2 hier mehrteilig ausgestaltet ist und dass das zuströmseitige Bauteil ein zuströmseitiges Gehäuseteil 4 mit angeformter Strahlzerlegeeinrichtung 5 ist. Dabei ist der zuströmseitige Stirnrandbereich des Gehäuseteils 4 als Dichtprofil 6 und die Strahlzerlegeeinrichtung 5 als Lochplatte ausgebildet.It is possible that the jet regulator housing is designed in one piece. In the Fig. 1 to 3 However, it can be seen that the jet regulator housing 2 is designed here in several parts and that the inflow-side component is an inflow-side housing part 4 with integrally formed jet decomposing device 5. In this case, the inflow-side end edge region of the Housing part 4 is designed as a sealing profile 6 and the jet disintegrating device 5 as a perforated plate.

In Gebrauchsstellung wirken das Dichtprofil 6 mit den Dichtlippen 6b lichten Auslauf-Querschnitt begrenzenden Stirnrandbereich der Auslaufarmatur zusammen.In the position of use, the sealing profile 6 cooperate with the sealing lips 6b clear outlet cross-section limiting end edge region of the outlet fitting.

Die Fig. 1 und 2 zeigen zwei Ausgestaltungen des Dichtprofils 6 mit jeweils zwei Dichtlippen 6b, die ringförmig umlaufend am zuströmseitigen Stirnrandbereich des Gehäuseteils 4 angeordnet sind. Dabei sind die Flanken der Dichtlippen 6b unterschiedlich abgeschrägt, um die Verformung in Gebrauchsstellung zu beeinflussen. Die in Fig. 1 dargestellten sich gegenüberliegenden schrägen Flanken bewirken, dass sich die Dichtlippen 6b in Gebrauchsstellung des Strahlreglers 1 auseinanderbiegen und so auch einen breiten Stirnrandbereich der Auslaufarmatur abdichten können. Fig. 2 zeigt zwei Dichtlippen 6b, die Schrägen jeweils an ihrer Außenseite aufweisen und in Gebrauchsstellung des Strahlreglers 1 dadurch zur Mitte des Strahlreglers 1 hin gebogen werden.The Fig. 1 and 2 show two embodiments of the sealing profile 6, each with two sealing lips 6b, which are arranged annularly circumferentially on the inflow-side end edge region of the housing part 4. The flanks of the sealing lips 6b are chamfered differently in order to influence the deformation in the position of use. In the Fig. 1 cause opposite oblique edges cause the sealing lips 6b bend apart in the position of use of the jet regulator 1 and so can also seal a wide end edge region of the outlet fitting. Fig. 2 shows two sealing lips 6b, the slopes each have on its outer side and are bent in the position of use of the jet regulator 1 thereby to the center of the jet regulator 1 out.

Fig. 3 zeigt eine vorteilhafte Ausgestaltung des Dichtprofils 6, wobei auf der Dichtprofilbasis 6a hier ringförmig umlaufende und nacheinander wirksam werdende Dichtlippen 6b vorgesehen sind, die stufenweise zueinander angeordnet sind und unterschiedlich abgestufte Höhen aufweisen. Diese Dichtlippen 6b werden mit zunehmendem, auf den Strahlregler 1 einwirkenden Einsetzdruck nacheinander wirksam. Dadurch ist es nach längerem Gebrauch des Strahlreglers 1 möglich, die Dichtwirkung durch Nachziehen des an der Auslaufarmatur verschraubten Auslaufmundstückes langzeitig aufrecht zu erhalten. Ist die höchste Dichtlippe 6b, die hier durch die radial äußerste Dichtlippe 6b gebildet wird, bereits etwas beschädigt oder abgenutzt oder unflexibel geworden, kann die in der Höhe nächstkommende Dichtlippe 6b die Dichtwirkung nach dem Festziehen wieder erreichen. Außerdem können eventuell kleine Unebenheiten des Gegenanschlags der Auslaufarmatur ausgeglichen werden. Fig. 3 shows an advantageous embodiment of the sealing profile 6, wherein on the sealing profile base 6a here annular circumferential and successively becoming effective sealing lips 6b are provided, which are arranged in steps to each other and have different graded heights. These sealing lips 6b are successively effective with increasing, acting on the jet regulator 1 insertion pressure. As a result, it is possible after prolonged use of the jet regulator 1 to sustain the sealing effect by tightening the outlet nozzle bolted to the outlet fitting for a long time. Is the highest sealing lip 6b here through the radially outermost sealing lip 6b is formed, already somewhat damaged or worn or become inflexible, the closest in height sealing lip 6b can reach the sealing effect after tightening again. In addition, any small bumps of the counter-stop of the outlet fitting can be compensated.

Claims (10)

  1. Flow regulator (1) having a flow regulator housing (2) that can be inserted in a sanitary outlet fitting, having a component on the inflow side that extends over the internal cross section of the outlet, and having a sealing profile (6) surrounding the flow regulator housing (2), which forms a seal between the flow regulator housing (2) on the one hand and the outlet fitting on the other hand and has at least two annularly encircling sealing lips (6b), the component on the inflow side being connected in one piece with the sealing profile (6), characterised in that the sealing lips (6b) have different heights and come into operation one after the other with an increasing insertion pressure acting on the flow regulator (1).
  2. Flow regulator according to claim 1, characterised in that the component on the inflow side is a housing part (4) with a flow fragmenting device (5) formed thereon.
  3. Flow regulator according to claim 1 or 2, characterised in that the end edge region of the housing part (4) on the inflow side is configured as the sealing profile (6).
  4. Flow regulator according to one of claims 1 to 3, characterised in that the sealing profile (6) has at least one contact seal and/or lip seal.
  5. Flow regulator according to one of claims 1 to 4, characterised in that the component on the inflow side has an insertion stop (7) which restricts any deformation of the sealing profile (6) in the position of use of the flow regulator (1).
  6. Flow regulator according to one of claims 1 to 5, characterised in that the sealing profile (6) has at least one seal with a sealing profile base (6a) in the form of an insertion stop (7).
  7. Flow regulator according to one of claims 1 to 6, characterised in that the sealing profile (6) and if appropriate its insertion stop (7) cooperates with an end edge region of the outlet fitting that delimits the internal cross-section.
  8. Flow regulator according to one of claims 1 to 7, characterised in that the insertion stop (7) is arranged adjacent to the sealing profile (6) in the radial direction.
  9. Flow regulator according to one of claims 1 to 8, characterised in that the sealing lips (6b) have graduated heights.
  10. Flow regulator according to one of claims 1 to 9, characterised in that the component on the inflow side and at least the sealing profile (6) connected in one piece therewith are made from the same material.
