Description

Die Erfindung betrifft einen Satz, bestehend aus einem sanitären Einbauteil, das an einer sanitären Wasserauslaufarmatur mühdungsseitig mittels einer Schraub- oder Renkverbindung lösbar gehalten ist, sowie aus einem Drehwerkzeug zum Lösen und Befestigen des sanitären Einbauteil drehfest ansetzbar und als Einbauteilgehäuse oder als ein, zur Befestigung eines Strahlreglers im Wasserauslauf einer sanitären Auslaufarmatur bestimmter Zwischenhalter ausgebildet ist, welches Einbauteilgehäuse oder welcher Zwischenhalter eine stirnseitige Profilierung oder Konturierung hat, die an einer an der Auslaufstirnseite des an der Wasserauslaufarmatur gehaltenen Einbauteiles vorgesehenen Gegenprofilierung oder -konturierung drehfest ansetzbar ist.The invention relates to a set consisting of a sanitary fixture, which is on a sanitary water outlet fitting mühdungsseitig releasably held by a screw or Renkverbindung, and from a rotary tool for releasing and securing the sanitary fixture rotatably attachable and as Einbausilgehäuse or as a, for attachment a jet regulator is formed in the water outlet of a sanitary outlet fitting certain intermediate holder, which Einbauteilgehäuse or which intermediate holder has an end profiling or contouring, which is rotatably attachable to a provided on the outlet end of the fixture held at the water outlet fitting counter-profiling or contouring.

An dem mündungsseitigen Auslaufende sanitärer Auslaufarmaturen ist üblicherweise ein Mundstück angeschraubt, in welchem ein Strahlregler eingesetzt ist. Dieser Strahlregler soll den zuströmenden Wasserstrom in einen homogenen perlend-weichen Wasserstrahl formen. Solche Strahlregler müssen in mehrjährigen Zeitintervallen ausgebaut und ausgetauscht werden. Um dazu das Mundstück von der Auslaufarmatur abschrauben und den im Mundstück befindlichen Strahlregler aus dem Mundstück entfernen zu können, hat man bereits ein ringschlüsselartiges Drehwerkzeug geschaffen, das von der Mündungsseite aus auf das Mundstück ausgeschoben und dort drehfest abgesetzt werden kann (vgl. DE 299 12 115 U1 ).At the mouth-side outlet end sanitary outlet fittings usually a mouthpiece is screwed, in which a jet regulator is used. This jet regulator is designed to form the inflowing stream of water into a homogeneous, sparkling, soft water jet. Such jet regulators must be removed and replaced at perennial time intervals. To do this, the mouthpiece from the outlet fitting unscrew and remove the jet regulator located in the mouthpiece from the mouthpiece, you have already created a ring-key-like turning tool, which can be pushed out of the mouth side on the mouthpiece and placed there against rotation (see. DE 299 12 115 U1 ).

In einem akuten Bedarfsfall steht dem Anwender dieses Drehwerkzeug jedoch meist nicht zur Verfügung. Vor allem aber ist die Herstellung und Anschaffung dieses Drehwerkzeuges mit einem zusätzlichen Kostenaufwand verbunden.However, in an acute requirement, this turning tool is usually not available to the user. But above all, the production and purchase of this turning tool is associated with an additional cost.

Aus der JP-S 49 142 455 UK 4 ist bereits ein Satz der eingangs erwähnten Art vorbekannt. Der vorbekannte Satz ist zur Montage am Wasserauslauf einer sanitären Auslaufarmatur vorgesehen, um dort ein unerwünschtes Tropfen der Auslaufarmatur nach dem Verschließen des in die Auslaüfarmatur integrierten Auslaufventils zu verhindern. Der vorbekannte Satz hat dazu mehrere Siebeinsätze, die bis zu einem Einsetzanschlag in ein als Einbauteilgehäuse oder als Zwischenhalter dienendes hülsenförmiges Drehwerkzeug einsetzbar sind. Dieses Drehwerkzeug, das an seinem Hülsenaußenumfang ein Außengewinde trägt, mit dem das Drehwerkzeug in ein Innengewinde am Wasserauslauf der sanitären Auslaufarmatur einschraubbar ist, weist an seinem abströmseitigen Stirnrand eine Profilierung oder Konturierung auf. Um den vorbekannten Satz im Wasserauslauf der sanitären Auslaufarmatur einsetzen zu können, sind die einzelnen Bestandteile zunächst ineinanderzufügen, bevor das als Einbauteilgehäuse oder als Zwischenhalter dienende Drehwerkzeug im Wasserauslauf montiert werden kann. Die Montage des aus den Bestandteilen bestehenden Satzes im Wasserauslauf und das Verschrauben des am Drehwerkzeug außenumfangsseitig vorgesehenen Außengewindes in dem im Wasserauslauf innenumfangsseitig angeordneten Innengewinde ist mit einem nicht unerheblichen Aufwand verbunden.From the JP-S 49 142 455 UK 4 already a sentence of the type mentioned above is already known. The previously known set is intended for mounting on the water outlet of a sanitary outlet fitting to prevent there unwanted dripping of the outlet fitting after closing the integrated in the Auslaüfarmatur outlet valve. The previously known set has for this purpose a plurality of sieve inserts which can be used up to an insertion stop in a sleeve-shaped rotary tool serving as a built-in housing or as an intermediate holder. This rotary tool, which carries an external thread on its sleeve outer circumference, with which the rotary tool can be screwed into an internal thread on the water outlet of the sanitary outlet fitting, has at its downstream end edge on a profiling or contouring. In order to use the previously known set in the water outlet of the sanitary outlet fitting, the individual components are first put together before the serving as Einbauteilgehäuse or as an intermediate holder rotary tool can be mounted in the water outlet. The assembly of the set consisting of the components in the water outlet and the screwing of the rotary tool on the outer peripheral side provided external thread in the water outlet inside circumference arranged internal thread is associated with a considerable effort.

Aus der US2002/0 129 442 A1 ist ein zur medizinischen Anwendung bestimmtes Zwei-Wege-Ventil beschrieben, das im Austausch gegen das übliche Auslaufmundstück mündungsseitig an eine sanitäre Auslaufarmatur angeschraubt werden kann. Das vorbekannten Zwei-Wege-Ventil erlaubt die wahlweise Umlenkung des Wasserstroms von einem stirnseitigen Wasserauslauf zu einem seitlich angeordneten Anschlusszapfen. Dabei ist an den Anschlusszapfen ein medizinischer Katheter anschließbar. Um das vorbekannte Zwei-Wege-Ventil an die sanitäre Auslaufarmatur anschließen zu können, ist am Außenumfang des hülsenförmigen Zwei-Wege-Ventils ein Außengewinde vorgesehen, das mit dem an der Auslaufarmatur mündungsseitig vorgesehenen Innengewinde korrespondiert. Das vorbekannte zwei-wege-Ventil weist auch an seinem der Auslaufarmatur abgewandten Gehäuseumfang ein weiteres umfangsseitiges Außengewinde auf, auf das ein Auslaufmundstück mit einem Innengewinde aufschraubbar ist.From the US2002 / 0129442 A1 is a designated for medical use two-way valve described, which can be screwed in exchange for the usual outlet mouthpiece on a sanitary outlet fitting. The previously known two-way valve allows the optional deflection of the water flow from a frontal water outlet to a laterally arranged connection pin. In this case, a medical catheter can be connected to the connecting pin. In order to connect the previously known two-way valve to the sanitary outlet fitting, an external thread is provided on the outer circumference of the sleeve-shaped two-way valve, which corresponds to the mouth side provided at the outlet fitting internal thread. The previously known two-way valve also has at its side facing away from the outlet fitting housing circumference on a further peripheral external thread on which an outlet nozzle with an internal thread can be screwed.

Aus der DE-A-198 . 51 151 ist ein Durchflußbegrenzer für Sanitärarmaturen bekannt, der ein scheibenförmiges Bauteil mit einer Anzahl von Durchflussöffnungen aufweist. In Strömungsrichtung vor den Durchflussöffnungen ist eine Halterung für ein Ventilelement in Form eines O-Ringes angeordnet. Der O-Ring ist so: in der Halterung gehalten, dass er von dem durch die Durchflussöffnungen fließenden Wasserstrom angesteuert und umströmt wird. Je nach Stärke der Strömung verformt er sich mehr oder weniger und verschließt dadurch den Strömungsquerschnitt mehr oder weniger weit. In dem scheibenförmigen Bauteil des vorbekannten Durchflußbegrenzers sind bogenförmige schlitzartige Nuten ausgebildet. Die Trennwand zwischen den bogenförmigen schlitzartigen Nuten und der den O-Ring aufnehmenden Nut ist an beiden Enden mit je einem radialen Steg über eine Schwachstelle verbunden. In den schlitzartigen Nuten sind Bogenkeile angebrdnet, die an einem Drehschieber einstückig angeformt sind. Verdreht man den Drehschieber, so gleiten die Bogenteile in den Nuten und drücken die Trennwand: an der Stelle, wo der Schlitz etwas enger ist, radial nach innen, was durch die Schwachstellen ermöglicht wird. Dadurch verringert sich der bei unverformtem O-Ring vorhandene radiale Abstand zwischen dem O-Ring und der Nutflanke und somit der Ausgangsströmungsquerschnitt bei nicht fließendem Wasser. Auf diese Weise lässt sich eine Veränderung des Sollwerts der Begrenzungsströmung erreichen.From the DE-A-198 , 51 151 a flow restrictor for sanitary fittings is known, which has a disc-shaped member having a number of flow openings. In the flow direction in front of the flow openings, a holder for a valve element in the form of an O-ring is arranged. The O-ring is so: held in the holder that it is driven and circulated by the water flow flowing through the flow openings. Depending on the strength of the flow, it deforms more or less and thus closes the flow cross-section more or less. In the disc-shaped component of the known flow restrictor arcuate slot-like grooves are formed. The partition between the arcuate slot-like grooves and the O-ring receiving groove is at both ends with one radial Jetty connected via a vulnerability. In the slot-like grooves arc wedges are betrrdnet, which are integrally formed on a rotary valve. Turning the rotary valve, the arch parts slide in the grooves and press the partition: at the point where the slot is slightly narrower, radially inward, which is made possible by the weak points. This reduces the existing at undeformed O-ring radial distance between the O-ring and the groove edge and thus the output flow cross-section with non-flowing water. In this way, a change in the setpoint of the limiting flow can be achieved.

Aus der DE 295 10 618 U1 ist bereits ein Strahlregler bekannt, der zum Anschluss an eine Auslaufarmatur bestimmt ist. Der vorbekannte Strahlregler weist ein zweiteiliges Strahlreglergehäuse auf, das in seinem anschlussseitigen Gehäuseteil einen Mengenregler und in seinem auslaufseitigen Gehäuseteil einen Strahlreglereinsatz trägt. Am Außenumfang der Gehäuseteile ist jeweils ein Außengewinde vorgesehen, so dass das auslaufseitige Gehäuseteil mit einem komplementären Innengewinde am anschlussseitigen Gehäuseteil und das anschlussseitige Gehäuseteil seinerseits: am Armaturenauslauf einer sanitären Auslaufarmatur befestigt werden kann. Die Gehäuseteile weisen an ihrem Gehäuse-Außenumfang jeweils eine Werkzeugangriffsfläche zum Ansetzen eines Schraubenschlüssels auf. Dabei ist nachteilig, dass beim Ansetzen eines Schraubenschlüssels am auslaufseitigen Gehäuseteil in Abhängigkeit von den an den Außengewinden erforderlichen Drehmomenten das anschlussseitige Gehäuseteil unbeabsichtigt mitdrehen kann. Ein unbeabsichtigtes Mitdrehen des anschlussseitigen Gehäuseteiles lässt sich somit nur vermeiden, wenn das anschlussseitige Gehäuseteil mit Hilfe eines weiteren Schraubenschlüssels in seiner Relativposition zur Anschlussarmatur gesichert wird, wobei sich das gleichzeitige Ansetzen zweier Schraubenschlüssel bei einem regelmäßig vergleichsweise kleinen Strahlregler sehr schwierig gestaltet.From the DE 295 10 618 U1 already a jet regulator is known, which is intended for connection to an outlet fitting. The previously known jet regulator has a two-part jet regulator housing which carries a flow regulator in its connection-side housing part and a jet regulator insert in its outlet-side housing part. On the outer circumference of the housing parts, an external thread is provided in each case, so that the outlet-side housing part with a complementary internal thread on the connection-side housing part and the connection-side housing part in turn: can be attached to the tap outlet of a sanitary outlet fitting. The housing parts each have a tool engagement surface for attaching a wrench on their housing outer circumference. It is disadvantageous that when attaching a wrench on the outlet side housing part in dependence on the torque required on the external threads, the connection-side housing part can rotate unintentionally. An unintentional co-rotation of the connection-side housing part can thus be avoided only if the connection-side housing part is secured by means of another wrench in its relative position to the connection fitting, wherein the simultaneous application of two wrenches designed very difficult at a regularly comparatively small aerator.

Es besteht daher die Aufgabe, einen Satz der eingangs erwähnten Art zu schaffen, der die oben beschriebenen Nachteile des vorbekannten Standes der Technik zu vermeiden hilft.It is therefore an object to provide a set of the type mentioned, which helps to avoid the disadvantages of the prior art, described above.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Satz der eingangs erwähnten Art darin, dass die stirnseitige Profilierung oder Konturierung des Drehwerkzeugs zumindest bereichsweise derart an die Gegenprofilierung oder -konturierung Einbauteils angepasst ist, dass diese in diesem Bereich aneinander einsetzbar und drehfest miteinander verbindbar sind.The achievement of this object is in the sentence of the type mentioned in that the end-side profiling or contouring of the rotary tool is at least partially adapted to the counter-profiling or-Konturing fixture that they can be used in this area together and rotatably connected to each other.

Der erfindungsgemäße Satz weist ein Drehwerkzeug auf, das als Einbauteilgehäuse oder als ein zur Befestigung eines Strahlreglers im Wasserauslauf einer sanitären Auslaufarmatur bestimmter Zwischenhalter ausgebildet ist. Da das Einbauteilgehäuse oder der Zwischenhalter vom Hersteller oder Anwender ohnehin benötigt wird, ist die Herstellung oder die Anschaffung dieses Drehwerkzeuges nicht mit wesentlichen zusätzlichen Kosten verbunden. Um das Drehwerkzeug zum Lösen und Befestigen eines an der Wasserauslaufarmatur befindlichen Einbauteiles drehfest ansetzen zu können, weist das als Drehwerkzeug dienende Einbauteilgehäuse oder der Zwischenhalter an seiner zu- oder abströmseitigen Stirnseite eine Profilierung oder Konturierung auf, die an einer an der Auslaufstirnseite des an der Wasserauslaufarmatur gehaltenen Einbauteiles vorgesehenen Gegenprofilierung oder-konturierung drehfest ansetzbar ist. Mit Hilfe dieses Drehwerkzeuges kann anschließend die Schraubverbindung oder Renkverbindung gelöst werden, die das an der Wasserauslaufarmatur befindliche Einbauteil dort bislang gehalten hat.The set according to the invention has a rotary tool which is designed as a built-in housing or as an intermediate holder intended for fastening a jet regulator in the water outlet of a sanitary outlet fitting. Since the built-in housing or the intermediate holder from the manufacturer or user is required anyway, the production or purchase of this turning tool is not associated with significant additional costs. In order to fix the rotary tool for loosening and securing a fitting located on the water outlet fitting built-in, serving as a rotary tool mounting housing or the intermediate holder on its inflow or outflow side end profiling or contouring, which at one of the outlet end of the water outlet fitting held fitting provided counter-profiling or contouring rotatably attached. With the help of this rotary tool can then be solved the screw or Renkverbindung which has been held at the water outlet fitting built-in there so far.

Damit das Drehwerkzeug besonders sicher und fest am Außen- oder Innenumfang des an der Wasserauslaufarmatur befindlichen Einbauteiles angesetzt werden kann, ist es vorteilhaft, wenn das Drehwerkzeug hülsenförmig ausgestaltet.So that the turning tool can be attached particularly securely and firmly to the outer or inner circumference of the fitting located on the water outlet fitting, it is advantageous if the turning tool is designed sleeve-shaped.

In bestimmten Anwendungsfällen kann es notwendig werden, einen belüfteten Strahlregler gegen einen unbelüfteten Strahlregler auszutauschen oder einen Durchflussbegrenzer gegen einen Durchflussmengenregler auszuwechseln. In solchen Einzelfällen können das Einbauteil eines als Drehwerkzeug dienenden Einbauteilgehäuses einerseits und das an der Wasserauslaufarmatur befindliche Einbauteil andererseits form- und funktionsverschieden sein. Eine bevorzugte Weiterbildung gemäß der Erfindung sieht jedoch vor, dass das Einbauteil des als Drehwerkzeug dienenden Einbauteilgehäuses mit dem an der Wasserauslaufarmatur gehaltenen Einbauteil funktionsidentisch und/oder formidentisch ist. So kann als Drehwerkzeug beispielsweise ein hülsenförmiges Einbauteilgehäuse dienen, das mit dem Einbauteilgehäuse des an der Wasserauslaufarmatur befindlichen Einbauteiles formidentisch ist. Ein solches Einbauteilgehäuse wird in großen Stückzahlen hergestellt, so dass jedem zur Erstausrüstung bestimmten Einbauteil vorsorglich auch ein als Drehwerkzeug dienendes Einbauteilgehäuse beigefügt werden kann, ohne dass dies mit besonderen zusätzlichen Kosten für den Hersteller oder den Anwender verbunden wäre.In certain applications, it may be necessary to replace a vented jet regulator with an unaerated jet regulator, or replace a flow restrictor with a flow regulator. In such individual cases, the mounting part of a mounting tool housing serving as a turning tool on the one hand and the fitting located on the water outlet fitting on the other hand may be different in shape and function. A preferred development according to the invention, however, provides that the mounting part of the insert tool housing serving as a rotary tool with the fixture held on the water outlet fitting is functionally identical and / or identical in shape. Thus, for example, serve as a rotary tool a sleeve-shaped built-in housing, which is identical to the form-fitting housing of the fitting located on the water outlet fitting. Such a built-in housing is manufactured in large numbers, so that each fitting for original equipment as a precaution also serving as a rotary tool mounting housing can be attached, without this being associated with special additional costs for the manufacturer or the user.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass die am Drehwerkzeug einerseits und an dem an der Wasserauslaufarmatur gehaltenen Einbauteil andererseits stirnrandseitig vorgesehenen und drehfest aneinander ansetzbaren Profilierungen oder Konturierungen kronenförmig ausgebildet sind.A preferred embodiment according to the invention provides that the on the rotary tool on the one hand and on the mounted on the water outlet fitting insert on the other hand provided at the end edge side and rotatable against each other attachable profiles or contours are crown-shaped.

Um dabei die formidentische Ausgestaltung der Einbauteile und ihrer Bestandteile zu erleichtern, sind die am Drehwerkzeug einerseits und dem an der Wasserauslaufarmatur lösbar gehaltenen Einbauteil andererseits vorgesehenen Profilierungen oder Konturierungen jeweils an der auslaufseitigen Stirnseite dieser Teile vorgesehen sind.To do this, the identical design of the built-in parts and facilitate their constituents, on the other hand provided on the rotary tool on the one hand and the water outlet fitting releasably mounted on the other part profiling or contouring are respectively provided on the outlet side end side of these parts.

Das erfindungsgemäße Drehwerkzeug ist in großen Stückzahlen insbesondere dort einsetzbar, wo das Drehwerkzeug einerseits und das an der Wasserauslaufarmatur lösbar gehaltene Einbauteil andererseits jeweils als Strahlregler oder zumindest als Bestandteil eines Strahlreglers auszugestalten sind.The turning tool according to the invention can be used in large numbers, in particular, where the turning tool on the one hand and the fixture detachably held on the water outlet fixture on the other hand each be designed as a jet regulator or at least as part of a jet regulator.

Weitere Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung eines erfindungsgemäßen Ausführungsbeispiels in Verbindung mit den Ansprüchen sowie der Zeichnung. Die vorliegende Erfindung wird anhand des nachfolgenden Ausführungsbeispiels noch näher erläutert.Further features of the invention will become apparent from the following description of an embodiment of the invention in conjunction with the claims and the drawings. The present invention will be explained in more detail with reference to the following embodiment.

In der einzigen Figur ist eine sanitäre Wasserauslaufarmatur 2 im Bereich ihres Auslaufendes 4 dargestellt. In die Wasserauslaufarmatur 2 ist von der Mündungsseite aus ein sanitäres Einbauteil 5 eingeschraubt, das hier als Strahlregler ausgestaltet ist und zuströmseitig ein Vorsatzsieb 14 hat. Am Einbaugehäuse des Einbauteiles 5 ist außenumfangsseitig, oberhalb einer Ringdichtung 11, ein Außengewinde 1 vorgesehen, das in ein Innengewinde 3 am Innenumfang der Wasserauslaufarmatur 2 einschraubbar ist.In the single figure, a sanitary water outlet fitting 2 is shown in the region of its outlet end 4. In the water outlet fitting 2 from the mouth side of a sanitary fitting 5 is screwed, which is designed here as a jet regulator and inflow has a front screen 14. On the housing of the installation part 5 is on the outer peripheral side, above a ring seal 11, an external thread 1 is provided, which is screwed into an internal thread 3 on the inner circumference of the water outlet fitting 2.

Um das an der Wasserauslaufarmatur 2 lösbar gehaltene und praktisch vollständig in die Wasserauslaufarmatur 2 einschraubbare Einbauteil 5 im Bedarfsfall verdrehen und aus seiner Schraubverbindung in der Wasserauslaufarmatur 2 lösen zu können, ist ein Drehwerkzeug erforderlich, das erfindungsgemäß ebenfalls als sanitäres Einbauteil 5' oder zumindest als Bestandteil eines sanitären Einbauteiles ausgestaltet ist.In order to turn the attached to the water outlet fitting 2 and practically completely screwed into the water outlet fitting 2 insert part 5 if necessary to solve and its screw in the water outlet fitting 2, a turning tool is required, the invention also as a sanitary fixture 5 'or at least as a component a sanitary fixture is designed.

Dabei sind das als Drehwerkzeug dienende und ebenfalls als Strahlregler funktionsidentisch ausgestaltete Einbauteil 5' und das in der Wasserauslaufarmatur 2 befindliche Einbauteil 5 formidentisch ausgestaltet.In this case, serving as a turning tool and also functionally identical designed as a jet regulator built-in part 5 'and located in the water outlet fitting 2 built-in part 5 are designed identical in shape.

Die Einbauteile 5, 5' weisen an den auslaufseitigen Stirnseiten ihrer Einbaugehäuse eine stirnseitige Profilierung beziehungsweise Gegenprofilierung auf. Diese Profilierungen und Gegenprofilierungen werden durch den jeweils kronenförmigen Gehäusestirnrand der Einbaugehäuse gebildet, wobei die am kronenförmigen Gehäusestirnrand vorgesehenen Ausnehmungen 24 und Vorsprünge 25 des einen Teils 5, 5' in die Vorsprünge 25 und Ausnehmungen 24 des jeweils anderen Teils 5', 5 eingreifen.The built-in parts 5, 5 'have on the outlet-side end faces of their installation housing an end-side profiling or counter profiling. These profiles and counter-profiles are formed by the respective crown-shaped housing end edge of the mounting housing, wherein the recesses 24 provided on the crown-shaped housing end edge and projections 25 of the one part 5, 5 'engage in the projections 25 and recesses 24 of the other part 5', 5.

In dem hier dargestellten Ausführungsbeispiel kann das in der Wasserauslaufarmatur 2 befindliche Einbauteil 5 mit Hilfe des zum Austausch bestimmten und hier form- und funktionsidentisch ausgestalteten Einbauteiles 5' ausgeschraubt werden, wobei das ebenfalls als Strahlregler dienende Einbauteil 5' anschließend mit Hilfe des ausgebauten Einbauteiles 5 in die Wasserauslaufarmatur einschraubbar ist. Während hier also zum Austausch des in der Wasserauslaufarmatur 2 befindlichen Einbauteiles 5 ein komplettes Einbauteil 5' verwendet wird, ist es demgegenüber auch möglich, zum Ausschrauben des in der Auslaufarmatur befindlichen Einbauteiles 5 lediglich das Einbaugehäuse eines ansonsten nicht mitgelieferten Einbauteiles zu verwenden. Dazu kann der Hersteller von Armaturen nur ein weiteres Einbaugehäuse mit der Armatur mitliefern, welches Einbaugehäuse als Drehwerkzeug bestimmt ist. Dies hat den Vorteil, dass der Armaturenhersteller keine zweite, in die Wasserauslaufarmatur 2 montierbare Funktionseinheit mitliefern muss und das weitere, als Drehwerkzeug bestimmte Einbaugehäuse, das in relativ großen Stückzahlen hergestellt und verwendet wird, ein sehr preisgünstiges Hilfswerkzeug darstellt.In the embodiment shown here, the built-in part 5 in the water outlet fitting 2 can be unscrewed using the designated for replacement and here form and functionally identical built-in 5 ', which also serves as a jet regulator insert 5' then with the help of the built-in fitting 5 in the water outlet fitting is screwed. While here, therefore, a complete built-in part 5 'is used to replace the located in the water outlet fitting 2 5, it is also possible to unscrew the fitting located in the outlet fitting 5 to use only the mounting housing of an otherwise not supplied built-in. For this purpose, the manufacturer of valves can only provide another installation housing with the fitting, which installation housing is intended as a turning tool. This has the advantage that the valve manufacturer does not have to supply a second functional unit which can be mounted in the water outlet fitting 2, and the further installation housing intended as a turning tool, which has a relatively large size Quantities produced and used is a very inexpensive utility tool.
