Abstract

In a sanitary water tap in the form of a single tap or a mixer tap with one or more operating levers, especially a single-lever mixer tap with water passages in the form of water inlets and at least one water outlet and with a fittings housing for the control components, especially those integrated into a cartridge, in which the inlet pipes forming the water inlets are connected to the cartridge via an insert adjacent the cartridge, contact between the water flowing through and parts of the fittings consisting of brass alloys containing lead is to be completely prevented. To this end, the water passages (52) are provided on the inside with a waterproof shield (53, 10, 6) consisting of lead-free material acceptable for health reasons to prevent contact with the water flowing through them.

Description

Die Erfindung betrifft ein sanitäres Wasserventil in der Form eines Einzel-Absperrventils oder eines Mischventils mit einem oder mehreren Betätigungsgriffen, insbesondere Einhebelmischventil mit Wasserwegen in der Form von Wasserzugängen und wenigstens eines Wasserabgangs oder Wasserauslaufs, und mit einem aus einer Bleibestandteile aufweisenden Metallegierung bestehenden Armaturengehäuse zur Aufnahme der Steuerelemente, welche insbesondere in einer Kartusche baueinheitlich vereinigt sind, wobei die die Wasserzugänge bildenden Zulaufrohre über ein der Kartusche benachbart angeordnetes Einsatzstück an die Kartusche angeschlossen sind.The invention relates to a sanitary water valve in the form of a single shut-off valve or a mixing valve with one or more actuation handles, in particular a single-lever mixer valve with water paths in the form of water inlets and at least one water outlet or water outlet, and with a fitting housing for accommodating a metal alloy comprising lead components of the control elements, which are combined in particular in a cartridge, the inlet pipes forming the water inlets being connected to the cartridge via an insert piece arranged adjacent to the cartridge.

Aufgrund der guten Ver- und Bearbeitbarkeit, der relativ hohen Festigkeit und der hervorragenden Korrosionsbeständigkeit werden sanitäre Armaturen zur Zuführung von Kalt-, Warm- und Mischwasser in überwiegendem Maße aus Kupfer-Zink-Legierungen, bekannt auch unter dem Sammelbegriff Messing, hergestellt, denen als spanbrechender Zusatz zur Verbesserung der spanabhebenden Bearbeitung als weiterer Legierungsbestandteil Blei hinzugefügt ist. Bekannt und durch wissenschaftliche Untersuchungen belegt ist auch, daß Schwermetalle, die auf unterschiedlichen Wegen in den menschlichen Körper gelangen können, zu schweren dauerhaften Erkrankungen führen.Due to the good machinability and machinability, the relatively high strength and the excellent corrosion resistance, sanitary fittings for supplying cold, warm and mixed water are predominantly made of copper-zinc alloys, also known under the collective term brass, to which chip breaking Additive to improve machining as a further alloy component lead is added. It is also known and proven by scientific studies that heavy metals, which can get into the human body in different ways, lead to serious permanent illnesses.

Untersuchungen haben ferner ergeben, daß Schwermetallanteile, vornehmlich Blei, in wasserführenden Leitungen und Armaturen aus bleihaltigen Legierungen von dem durchfließenden Frischwasser aufgenommen und so über das Trinkwasser dem menschlichen Organismus zugeführt werden. Aufgrund der damit verbundenen Gefahren bestehen in einigen Ländern Bestrebungen, den Einsatz von Sanitärarmaturen aus den bisher verwendeten bleihaltigen Kupfer-Zink-Legierungen zu unterbinden. In einigen Ländern sind daher sanitäre Armaturen aus Messing und anderen bleihaltigen Legierungen unerwünscht, wenn die Gefahr besteht, daß durch den Kontakt der wasserführenden Teile einer Armatur mit dem durchfließenden Wasser Schwermetalle, wie Blei, von dem Wasser aufgenommen werden können.Studies have also shown that heavy metal components, primarily lead, in water-carrying pipes and fittings made of lead-containing alloys are taken up by the fresh water flowing through and are thus supplied to the human organism via the drinking water. Due to the associated dangers, efforts are being made in some countries to prevent the use of sanitary fittings made of the lead-containing copper-zinc alloys previously used. In some countries, sanitary fittings made of brass and other lead-containing alloys are therefore undesirable if there is a risk that heavy metals, such as lead, can be absorbed by the water due to the contact of the water-carrying parts of a fitting with the water flowing through.

Neben den üblichen Messingarmaturen sind bereits sanitäre Mischbatterien vorgeschlagen, deren wasserführende Teile und Funktionselemente im wesentlichen aus gesundheitlich unbedenklichen Materialien hergestellt sind. Diese weiterentwickelten Mischbatterien, zum Beispiel Einlochmischbatterien, besitzen ein Einsatzstück aus einer Messinglegierung, in denen die aus Kupfer hergestellten Zuflußrohre für das kalte und warme Wasser und gegebenenfalls ein aus Kupfer bestehendes Auslaufrohr druckdicht eingesetzt sind. Mit diesem Einsatzstück ist die aus Kunststoff und Keramik bestehende Kartusche für die Mengen- und Temperatursteuerung des Wassers gegebenenfalls unter Zwischenschaltung weiterer Funktionsgruppen durch Ankerschrauben druckdicht verspannt. Bei diesen weiterentwickelten Sanitärarmaturen sind die Stellen, an denen das Wasser mit den aus einer Messinglegierung hergestellten Baugruppen in Kontakt kommen kann, schon weitgehend vermindert. Die Aufnahme von gesundheitsgefährdenden Legierungsbestandteilen durch das Wasser ist damit durchaus begrenzt. Trotz der weitgehenden Sicherung einer hohen Wasserqualität verbleiben aber in dem aus einer Kupfer-Zink-Legierung bestehenden Einsatzstück im Bereich der Anschlüsse der druckdicht eingesetzten Zu- und gegebenenfalls Auslaufrohre für das Kalt-, Warm- und Mischwasser Kontaktstellen, an denen gesundheitsgefährdende Legierungsbestandteile vom Wasser aufgenommen werden können. Auch wenn es sich hierbei um vergleichsweise äußerst geringe Anteilmengen handelt, sind diese mit hochmodernen Analysenmeßgeräten nachweisbar und können unter Umständen zu nachteiligen Konsequenzen für den Hersteller führen.In addition to the usual brass fittings, sanitary mixer taps have already been proposed, the water-carrying parts and functional elements of which are essentially made from materials that are harmless to health. These further developed mixer taps, for example single-hole mixer taps, have an insert made of a brass alloy, in which the inflow pipes made of copper for the cold and warm water and optionally an outlet pipe made of copper are inserted in a pressure-tight manner. With this insert, the cartridge made of plastic and ceramic for the quantity and temperature control of the water is optionally with additional functional groups interposed, pressure-tight by anchor bolts. With these further developed sanitary fittings, the places where the water can come into contact with the assemblies made of a brass alloy have already been largely reduced. The absorption of health-hazardous alloy components by the water is therefore quite limited. Despite the extensive assurance of high water quality, contact points remain in the insert made of a copper-zinc alloy in the area of the connections of the pressure-tight inlet and outlet pipes for the cold, warm and mixed water, at which health-hazardous alloy components are absorbed by the water can be. Even if these are comparatively extremely small quantities, they can be detected with state-of-the-art analytical measuring devices and may lead to disadvantageous consequences for the manufacturer.

Der Erfindung liegt die Aufgabe zugrunde, die Kontaktstellen zwischen Wasser und den aus einer Messinglegierung bestehenden Bauteilen vollständig zu beseitigen und eine vollkommen "bleifreie" Sanitär-Mischbatterie zu schaffen.The invention has for its object to completely eliminate the contact points between water and the components consisting of a brass alloy and to create a completely "lead-free" sanitary mixer tap.

Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.This object is achieved, including advantageous refinements and developments of the invention, from the content of the patent claims, which follow this description.

Die Erfindung sieht in ihrem Grundgedanken vor, daß die Wasserwege innenseitig zur Vermeidung eines Kontaktes mit dem durch sie geführten Wasser mittels einer aus einem gesundheitlich unbedenklichen bleifreien Material bestehenden wasserdichten Abschirmung versehen sind.The basic idea of the invention provides that the waterways are provided on the inside to avoid contact with the water that is passed through them by means of a waterproof shield consisting of a lead-free material that is harmless to health.

Damit ist der Vorteil verbunden, daß ein Kontakt zwischen dem Wasser und bleihaltigen Legierungsteilen der Armatur ausgeschlossen ist.This has the advantage that contact between the water and lead-containing alloy parts of the fitting is excluded.

In der US-PS 4 979 539 ist ein sanitäres Wasserventil beschrieben, bei welchem der Armaturenkörper aus Keramik besteht, und zur Vermeidung einer Beaufschlagung des Armaturenkörpers mit dem in den Wasserwegen herrschenden Wasserdruck ist die Ausgangsöffnung der Kartusche mittels einer flexiblen gesonderten Leitung mit dem Wasserauslauf der Armatur verbunden. Somit liegt dieser vorbekannten Lösung eine andere Aufgabe zugrunde.In US-PS 4 979 539 a sanitary water valve is described in which the valve body is made of ceramic, and in order to prevent the valve body from being exposed to the water pressure in the waterways, the outlet opening of the cartridge is connected to the water outlet by means of a flexible separate line Armature connected. This previously known solution is therefore based on another task.

Nach einer ersten vorteilhaften Ausführungsform der Erfindung besteht die Abschirmung aus einer auf die Innenseite der Wasserwege aufgebrachten Beschichtung aus einem gesundheitlich unbedenklichen bleifreien Material, wobei zusätzlich das Einsatzstück zum Anschluß der Zulaufrohre aus Kunststoff besteht; in diesem Fall können auch sogenannte offene Kartuschen verwendet werden, bei denen das Wasser aus der Kartusche selbst in den mit einer entsprechenden Innenauskleidung versehenen Wasserweg eintritt; da alle Teile, mit denen das Wasser in Berührung kommt, aus bleifreiem Material bestehen, ist ein Kontakt des Wassers mit bleihaltigen Armaturenteilen nicht gegeben.According to a first advantageous embodiment of the invention, the shield consists of a coating applied to the inside of the waterways and made of a lead-free material which is harmless to health, the insert for connecting the inlet pipes additionally being made of plastic; in this case so-called open cartridges can also be used, in which the water from the cartridge itself enters the water path provided with a corresponding inner lining; Since all parts with which the water comes into contact are made of lead-free material, the water does not come into contact with fittings containing lead.

Eine alternative Ausführungsform der Erfindung sieht vor, daß die Abschirmung als ein in die Wasserwege eingelegter, aus gesundheitlich unbedenklichem, bleifreien Material hergestellter separater rohr- oder schlauchförmiger Wasserkanal ausgebildet ist, wobei dieser Wasserkanal gegenüber den aus einer bleihaltigen Messinglegierung bestehenden Bau- und Funktionsgruppen vollständig abgedichtet ist. Nach einem Ausführungsbeispiel der Erfindung ist der separate Wasserkanal ebenso wie die Zulaufrohre über eine zusätzliche Bohrung in dem Einsatzstück mit der Kartusche verbunden, so daß das Mischwasser von der Kartusche unmittelbar in den separaten Wasserkanal eintritt und hier ohne Berührung mit bleihaltigen Armaturenteilen zum Auslaufkopf geführt ist.An alternative embodiment of the invention provides that the shielding is designed as a separate tubular or tubular water channel inserted into the waterways and made of unhealthy, lead-free material, this water channel being opposite the assembly and functional groups consisting of a brass alloy containing lead is completely sealed. According to an embodiment of the invention, the separate water channel as well as the feed pipes are connected to the cartridge via an additional hole in the insert, so that the mixed water from the cartridge enters the separate water channel directly and is led to the outlet head without touching lead-containing fittings.

Wie schon angesprochen, bestehen die Einsatzstücke zum Anschluß der Zulaufrohre in der Regel aus bleihaltigem Messing, und zur Vermeidung eines Kontaktes des Wassers mit dem bleihaltigen Messing in diesem Bereich sieht ein Ausführungsbeispiel der Erfindung vor, zwischen Kartusche und dem aus bleihaltigen Messing bestehenden Einsatzstück eine aus einem gesundheitlich unbedenklichen Material hergestellte Scheibe zum Anschluß der Zulaufrohre und des separaten Wasserkanals unter Einschluß von zugeordneten Dichtelementen anzuordnen und druckdicht zu verspannen; damit ist gewährleistet, daß sowohl die Zulaufrohre als auch der separate Wasserkanal durch das aus bleihaltigem Messing bestehende Einsatzstück hindurchgeführt sind und erst über die zwischengelegte Scheibe in die Kartusche münden, wobei zwischen der Scheibe und dem Einsatzstück zusätzliche Dichtelemente angeordnet sind, die einen Rückfluß des Wassers von der Kartusche über die Scheibe zu dem Einsatzstück verhindern. Nach einem Ausführungsbeispiel der Erfindung ist die zwischengelegte Scheibe aus einem korrosionsbeständigen Stahl gefertigt, so daß sie in der Lage ist, die bei der Verspannung der Funktionsbaugruppen miteinander auftretenden Kräfte aufzunehmen.As already mentioned, the inserts for connecting the inlet pipes are usually made of lead Brass, and in order to avoid contact of the water with the brass containing lead in this area, an embodiment of the invention provides, between the cartridge and the insert piece made of lead-containing brass, a disk made of a material which is harmless to health, for connecting the inlet pipes and the separate water duct, including the inclusion to arrange of associated sealing elements and to clamp them pressure-tight; this ensures that both the inlet pipes and the separate water channel are passed through the insert piece made of lead-containing brass and only open into the cartridge via the interposed disc, additional sealing elements being arranged between the disc and the insert, which ensure a backflow of the water prevent from the cartridge over the disc to the insert. According to one embodiment of the invention, the interposed disc is made of a corrosion-resistant steel, so that it is able to absorb the forces that occur when the functional modules are braced.

Nach einem Ausführungsbeispiel sind die im Bereich der Anschlüsse des Einsatzstückes, in denen die Zulaufrohre für das kalte und warme Wasser und der separate Wasserkanal beispielsweise durch Hartlötung eingesetzt sind, angeordneten Dichtelemente vorzugsweise in Aussparungen des Einsatzstückes eingelegt und liegen nach dem Verspannen der Kartusche mit dem Einsatzstück flüssigkeitsdicht die eingesetzten Rohre umschließend an den Wänden der Aussparungen an.According to one embodiment, the sealing elements arranged in the area of the connections of the insert, in which the supply pipes for the cold and warm water and the separate water channel are inserted, for example by brazing, are preferably inserted into recesses in the insert and lie after the cartridge has been braced with the insert the pipes inserted around the walls of the recesses in a liquid-tight manner.

An dem auslaufseitigen Ende des separaten Wasserkanals befindet sich ein Auslaufkopf, der unter Zwischenschaltung eines Dichtelementes formschlüssig mit dem Armaturengehäuse verbunden ist.At the outlet-side end of the separate water channel there is an outlet head which is positively connected to the valve body with the interposition of a sealing element.

Der Auslaufkopf wird mittels eines zylinderförmigen Dichtelementes auf den separaten Wasserkanal aufgesteckt und durch eine Öffnung des Armaturengehäuses hindurchgeführt, wobei das Dichtelement zwei äußere Ringschultern aufweist, zwischen denen der Aufnahmeabschnitt des Auslaufkopfes aufgenommen und lagegesichert fixiert ist.The outlet head is plugged onto the separate water channel by means of a cylindrical sealing element and passed through an opening in the fitting housing, the sealing element having two outer annular shoulders, between which the receiving section of the outlet head is received and secured in position.

In einer modifizierten Ausführung dieser Befestigung besitzt der Auslaufkopf einlaufseitig eine zylinderförmige Verlängerung seines Aufnahmeabschnittes mit einem einwärts gerichteten Rastzapfen, der in eine korrespondierende Öffnung des Armaturengehäuses eingreift. Die druckdichte Verbindung zwischen dem Auslaufkopf und dem auslaufseitigen Ende des separaten Wasserkanals wird wiederum durch ein zylinderförmiges Dichtelement sichergestellt, das eine äußere Ringschulter aufweist, die radial in einer Aufnahmebohrung des Auslaufkopfes anliegt, und mit einer weiteren inneren Ringschulter versehen ist, die mit ihrem inneren Abschnitt an der Stirnfläche des separaten Wasserkanals oder eines eingelegten Zwischenstückes und mit ihrer äußeren Stirnfläche an einem Ansatz in der Aufnahmebohrung des Auslaufkopfes anschlägt.In a modified embodiment of this attachment, the outlet head has a cylindrical extension of its receiving section on the inlet side with an inwardly directed locking pin which engages in a corresponding opening in the valve body. The pressure-tight connection between the outlet head and the outlet-side end of the separate water channel is in turn ensured by a cylindrical sealing element which has an outer annular shoulder which lies radially in a receiving bore of the outlet head and is provided with a further inner annular shoulder which has its inner section strikes on the end face of the separate water channel or an inserted intermediate piece and with its outer end face on a shoulder in the receiving bore of the discharge head.

Bei Einlochmischbatterien, die zwischen der Kartusche und dem Einsatzstück einen Flüssigkeitsverteiler aufweisen, der von einem Kunststoffgehäuse umschlossen ist und zusammen mit dem Einsatzstück in einen Grundkörper des Armaturengehäuses eingesetzt ist, ist das einlaufseitige Ende des separaten Wasserkanals wiederum unter Verwendung eines zylinderförmigen Dichtungselemtes in eine Auslauföffnung des Kunststoffgehäuses druckdicht eingesetzt. In entsprechende Ausnehmungen des Einsatzstückes sind zusätzliche Dichtelemente eingelegt, die beim druckdichten Verspannen von Kartusche, Flüssigkeitsverteiler und Einsatzstück die Zulaufrohre umschließen und eine flüssigkeitsdichte Isolierung zwischen dem aus einer Messinglegierung hergestellten Einsatzstück und den wasserführenden Funktionselemten gewährleisten.In the case of single-hole mixer taps, which have a liquid distributor between the cartridge and the insert, which is enclosed by a plastic housing and which is inserted together with the insert into a base body of the fitting housing, the inlet-side end of the separate water channel is in turn inserted into an outlet opening of the using a cylindrical sealing element Plastic housing used pressure-tight. In corresponding recesses of the insert, additional sealing elements are inserted, which the pressure-tight clamping of the cartridge, liquid distributor and insert Enclose inlet pipes and ensure liquid-tight insulation between the insert made of a brass alloy and the water-carrying functional elements.

Die erfindungsgemäß vorgeschlagene Ausbildung für sanitäre Wasserventile, insbesondere für Einlochmischbatterien unterschiedlichster Ausführungen, nutzt einerseits die vorteilhaften Eigenschaften von Messinglegierungen für bestimmte Funktionsbaugruppen, wie beispielsweise ihre relativ hohe Festigkeit und ihre guten Eigenschaften für die Ver- und Bearbeitung aus und gewährleistet unter Einsatz relativ einfacher Mittel, daß jeder Kontakt des Wassers mit diesen Funktionsbaugruppen ausgeschlossen ist. Da sämtliche wasserführenden oder mit Wasser in Kontakt kommenden Bau- und Funktionsgruppen aus gesundheitlich unbedenklichen Materialien hergestellt oder mit einer entsprechenden Auskleidung versehen sind, entsteht auf diese Weise ein sanitäres Wasserventil, bei dem die Möglichkeit einer Aufnahme von Schwermetall-Legierungsbestandteilen durch das Wasser vollständig ausgeschlossen ist.The design proposed according to the invention for sanitary water valves, in particular for single-hole mixer taps of the most varied designs, uses on the one hand the advantageous properties of brass alloys for certain functional assemblies, such as their relatively high strength and their good properties for processing and processing, and ensures using relatively simple means, that any contact of the water with these functional modules is excluded. Since all water-bearing or water-contacting components and functional groups are made of materials that are harmless to health or are provided with a suitable lining, a sanitary water valve is created in this way, in which the possibility of absorption of heavy metal alloy components by the water is completely excluded .

Eine nach der Erfindung ausgebildete Einlochmischbatterie 1, wie in den Figuren 1 und 2 dargestellt, mit einem Betätigungsgestänge 46 für ein Auslaufventil ist mit ihren Zulaufrohren 11 für das kalte und warme Wasser in einer Aufnahmebohrung 4 eines Wasch- oder Spültisches 3 eingesetzt und auf bekannte Weise - über einen Zuganker 54 - mit dem Wasch-/Spültisch 3 fest verbunden (Figur 2).A single-hole mixer tap 1 designed according to the invention, as shown in FIGS. 1 and 2, with an actuating linkage 46 for an outlet valve is also included their inlet pipes 11 for the cold and warm water in a receiving bore 4 of a wash or sink 3 and used in a known manner - via a tie rod 54 - firmly connected to the wash / sink 3 (Figure 2).

Die Einlochmischbatterie 1 nach Figur 1 besitzt ein in sich geschlossenes Armaturengehäuse 2 aus einer bleihaltigen Messinglegierung, in das ein mit der Kartusche 5 druckdicht verbundendes Einsatzstück 8 eingesetzt und durch eine Schraube 55 mit dem Gehäuse 2 verschraubt ist. Am Auslauf des Armaturengehäuses 2 ist ein Auslaufkopf 51 aus einem gesundheitlich unbedenklichen Material aufgesteckt, und der Wasserweg 52 zwischen dem Auslaufkopf 51 und dem Einsatzstück 8 ist mit einer wasserdichten Beschichtung 53 aus einem gesundheitlich unbedenklichen bleifreien Material ausgekleidet. Die Beschichtung 53 kann beispielsweise in einem Tauchverfahren aufgetragen werden. In das aus Kunststoff bestehende Einsatzstück 8 sind die Zulaufleitungen 11 für das kalte und warme Wasser druckdicht eingesetzt, wobei im Bereich der Anschlußstellen dieser Leitungen jeweils zusätzliche Dichtelemente 7 vorgesehen sind. Durch Verspannung der Kartusche 5 mit dem Einsatzstück 8 wird im Zusammenwirken mit den Dichtelementen eine flüssigkeitsdichte Verbindung hergestellt.The single-hole mixer tap 1 according to FIG. 1 has a self-contained fitting housing 2 made of a lead-containing brass alloy, into which an insert 8 which is pressure-tightly connected to the cartridge 5 is inserted and is screwed to the housing 2 by a screw 55. At the outlet of the valve housing 2, an outlet head 51 made of a material which is harmless to health is attached, and the water path 52 between the outlet head 51 and the insert 8 is lined with a waterproof coating 53 made of a lead-free material which is harmless to health. The coating 53 can be applied, for example, in an immersion process. In the plastic insert 8, the supply lines 11 for the cold and warm water are inserted pressure-tight, additional sealing elements 7 being provided in the area of the connection points of these lines. By tightening the cartridge 5 with the insert 8, a liquid-tight connection is produced in cooperation with the sealing elements.

Bei diesem Ausführungsbeispiel wird das Wasser über das aus Kunststoff bestehende Einsatzstück 8 in die Kartusche 5 und von hier aus ebenfalls über das Einsatzstück 8 in den Wasserweg 52 geleitet, in welchem es zum Auslaufkopf 51 strömt; da die Innenseite des zum Armaturengehäuse 2 gehörenden Auslaufes mit einer Beschichtung 53 aus einem geeigneten Material versehen ist, kommt das Wasser an keiner Stelle mit bleihaltigen Legierungsteilen in Berührung.In this embodiment, the water is passed through the plastic insert 8 into the cartridge 5 and from here also via the insert 8 into the water path 52, in which it flows to the outlet head 51; since the inside of the spout belonging to the fitting housing 2 is provided with a coating 53 made of a suitable material, the water does not come into contact with lead-containing alloy parts at any point.

In Figur 2 ist ein Ausführungsbeispiel der Erfindung dargestellt, bei welchem zur Vermeidung eines Kontaktes zwischen dem Wasser und aus bleihaltigem Messing bestehenden Legierungsteilen zwischen der Kartusche 5 und dem Auslaufkopf 9 ein separater Wasserkanal 10 aus einem gesundheitlich unbedenklichen Material angeordnet ist. Die Zulaufrohre 11 für das kalte und warme Wasser und der separate Wasserkanal 10, welche beispielsweise aus Kupfer bestehen, sind zunächst durch Hartlötung druckdicht in das in diesem Fall aus einer Messinglegierung bestehende Einsatzstück 8 eingesetzt. Zum Anschluß der Leitungen 10, 11 an die Kartusche 5 ist aber zwischen dem Einsatzstück 8 und der Kartusche 5 eine zusätzliche Scheibe 6 aus einem gesundheitlich unbedenklichen Material, vorzugsweise einer korrosionsbeständigen Stahllegierung angeordnet, wobei die Leitungen 10, 11 durch das Einsatzstück 8 hindurch bis in die Scheibe 6 geführt und hier gehaltert sind; zwischen der Scheibe 6 und dem Einsatzstück 8 sind zusätzliche Dichtelemente 7 vorgesehen, die in Aussparungen 16 im Einsatzstück 8 eingelegt sind; die Dichtelemente 7 umschließen nach Verspannen des Einsatzstückes 8 mit der aus Keramik oder Kunststoff hergestellten Kartusche 5 und der zwischen Einsatzstück 8 und Kartusche 5 eingelegten Scheibe 6 mit Hilfe der Zuganker 48 flüssigkeitsdicht die eingesetzten Rohre 10, 11 und liegen flüssigkeitsdicht an den Wänden der Aussparung 16 an. Damit ist gewährleistet, daß jeder Kontakt des durchfließenden Wassers mit dem aus einer Messinglegierung hergestellten Einsatzstück 8 unterbunden ist und somit keine gesundheitsgefährdenden Legierungsbestandteile durch das Wasser aufgenommen und über das Trinkwasser in den menschlichen Organismus gelangen können.FIG. 2 shows an exemplary embodiment of the invention in which, in order to avoid contact between the water and alloy parts consisting of lead-containing brass, a separate water channel 10 made of a material which is harmless to health is arranged between the cartridge 5 and the outlet head 9. The inlet pipes 11 for the cold and warm water and the separate water channel 10, which consist, for example, of copper, are first inserted pressure-tight into the insert 8, which in this case consists of a brass alloy, by brazing. For connecting the lines 10, 11 to the cartridge 5, an additional disk 6 made of a material which is harmless to health, preferably a corrosion-resistant steel alloy, is arranged between the insert 8 and the cartridge 5, the lines 10, 11 through the insert 8 through to the disc 6 are guided and held here; additional sealing elements 7 are provided between the disk 6 and the insert 8, which are inserted into recesses 16 in the insert 8; After tightening the insert 8 with the cartridge 5 made of ceramic or plastic and the disc 6 inserted between the insert 8 and cartridge 5, the sealing elements 7 enclose the inserted tubes 10, 11 in a liquid-tight manner with the aid of the tie rods 48 and lie liquid-tight on the walls of the recess 16 at. This ensures that any contact of the water flowing through with the insert 8 made of a brass alloy is prevented and thus no health-threatening alloy components are absorbed by the water and can reach the human organism through the drinking water.

Wie Figur 3 deutlicher zu entnehmen ist, ist auf das auslaufseitige Ende des separaten Wasserkanals 10 unter Verwendung eines zylinderförmigen Dichtelementes 14 ein Auslaufkopf 9 aufgesteckt, der durch eine Öffnung 47 im Armaturengehäuse hindurchgeführt ist. In der vorliegenden Ausführung ist dieser Teil des Armaturengehäuses 2 als Blende 49, die beispielsweise wie das Armaturengehäuse 2 verchromt ist ausgebildet und durch eine Schraube 50 mit dem Armaturengehäuse 2 verbunden.As can be seen more clearly in FIG. 3, an outlet head 9 is attached to the outlet-side end of the separate water channel 10 using a cylindrical sealing element 14 and is passed through an opening 47 in the fitting housing. In the present embodiment, this part of the valve housing 2 is designed as a cover 49, which, for example, is chrome-plated like the valve housing 2 and is connected to the valve housing 2 by a screw 50.

Das Dichtelement 14 besitzt zwei äußere Ringschultern 12, 13, zwischen denen die einlaufseitige Aufnahme 45 des Auslaufkopfes 9 druckdicht und lagegesichert angeordnet ist. Das Dichtelement 14 ist ferner mit einer Einlaufschräge 15 versehen, die das Aufstecken des Dichtelementes 14 zusammen mit dem Auslaufkopf 9 auf den separaten Wasserkanal 10 erleichtert. In Übereinstimmung mit dem Gegenstand der vorliegenden Erfindung ist der Auslaufkopf 9 ebenfalls aus einem gesundheitlich unbedenklichen Material, vorzugsweise aus Kunststoff, hergestellt.The sealing element 14 has two outer annular shoulders 12, 13, between which the inlet-side receptacle 45 of the outlet head 9 is arranged pressure-tight and secured in position. The sealing element 14 is also provided with an inlet slope 15, which facilitates the plugging of the sealing element 14 together with the outlet head 9 onto the separate water channel 10. In accordance with the subject matter of the present invention, the discharge head 9 is also made of a material which is harmless to health, preferably of plastic.

Figur 4 zeigt eine Einlochmischbatterie 1, welche mit einem Flüssigkeitsverteiler 20 versehen ist, mittels dessen eine Umschaltung des Wasserauslaufes zwischen dem in diesem Fall mit 18 bezeichneten zur Mischbatterie 1 gehörigen Auslaufkopf und einer gesonderten Auslaufeinrichtung, beispielsweise in Form einer zusätzlich zur Mischbatterie 1 anzuordnenden Handbrause, die über eine weitere Rohrleitung 19 mit der Kartusche 5 verbunden ist, durchführbar ist. Der Flüssigkeitsverteiler 20 ist druckdicht in einem Kunststoffgehäuse 17, das mit einer Auslauföffnung 23 versehen ist, eingesetzt und unter Zwischenschaltung von in diesem Fall zwei Scheiben 6 aus einer korrosionsbeständigen Stahllegierung zwischen dem auch in diesem Fall aus einer Messinglegierung bestehenden Einsatzstück 8 und der Kartusche 5 angeordnet und zusammen mit diesen Baugruppen durch Zuganker 48 auf bekannte Weise verspannt. Die Zulaufrohre 11 wie auch das zur gesonderten Auslaufeinrichtung wegführende weitere Rohr 19 für das Mischwasser sind wiederum in das Einsatzstück 8 eingesetzt, wobei im Bereich der Anschlußstellen zu der Scheibe 6 erfindungsgemäß Dichtelemente 7 eingesetzt sind, die zusammen mit den vorgenannten Baugruppen verspannt werden und eine flüssigkeitsdichte Verbindung zwischen den wasserführenden Teilen und dem Einsatzstück gewährleisten.FIG. 4 shows a single-hole mixer tap 1, which is provided with a liquid distributor 20, by means of which a switchover of the water outlet between the outlet head designated in this case with 18 belonging to the mixer tap 1 and a separate outlet device, for example in the form of a hand shower to be arranged in addition to the mixer tap 1, which is connected to the cartridge 5 via a further pipeline 19, can be carried out. The liquid distributor 20 is pressure-tight in a plastic housing 17, which is provided with an outlet opening 23, and with the interposition of in this case, two disks 6 made of a corrosion-resistant steel alloy are arranged between the insert piece 8, which in this case also consists of a brass alloy, and the cartridge 5 and braced together with these assemblies by tie rods 48 in a known manner. The inlet pipes 11 as well as the further pipe 19 leading to the separate outlet device for the mixed water are in turn inserted into the insert 8, sealing elements 7 according to the invention being used in the area of the connection points to the disk 6, which are clamped together with the aforementioned assemblies and are liquid-tight Ensure connection between the water-carrying parts and the insert.

In die Auslauföffnung 23 des Kunststoffgehäuses 17 ist der separate Wasserkanal 10 mit seinem einlaufseitigen Ende mittels eines zylinderförmigen Dichtelementes 22 druckdicht eingesetzt, während auf dem auslaufseitigen Ende des separaten Wasserkanals 10 ein Auslaufkopf 18 ebenfalls mit Hilfe eines zylinderförmigen Dichtelementes 27 druckdicht aufgesteckt und formschlüssig mit dem Armaturengehäuse 2 verbunden ist. Hierzu weist der Auslaufkopf 18 - wie Figur 5 im einzelnen zu entnehmen ist - einlaufseitig eine Verlängerung 24 auf, die mit einem Rastzapfen 25 versehen ist. Der Rastzapfen 25 greift in eine Öffnung 26 des Armaturengehäuses 2 ein und gewährleistet so eine lagesichere Fixierung des Auslaufkopfes 18. Das zylinderförmige Dichtelement 27 zur druckdichten Verbindung von Auslaufkopf 18 und separatem Wasserkanal 10 weist eine äußere Ringschulter 28 auf, die radial in der Aufnahmebohrung 35 des Auslaufkopfes 18 anliegt und ist ferner mit einer inneren Ringschulter 29 versehen, die mit ihrem inneren Abschnitt 21 an der Stirnfläche des separaten Wasserkanals 10 beziehungsweise an einem eingelegten Zwischenstück 30 anliegt und mit ihrer äußeren Stirnfläche 34 an einem Ansatz 33 der Aufnahme 35 des Auslaufkopfes 18 anschlägt. Die einlaufseitig angebrachte Schräge 32 des Dichtelementes 27 erleichtert wiederum das Aufsetzen des Auslaufkopfes auf den separaten Wasserkanal 10. Das Dichtelement 22, mit dem das einlaufseitige Ende des separaten Wasserkanals 10 in die Auslauföffnung 23 des Kunststoffgehäuses 17 eingesetzt ist, besitzt eine analoge Konfiguration wie das Dichtelement 27 am Auslaufende. Die äußere Ringschulter 28 des Dichtelementes 22 liegt an der Stirnfläche 37 beziehungsweise in einer Ausnehmung 38 der Auslauföffnung 23 druckdicht an, während die innere Ringschulter 29 die Einstecktiefe des Auslaufrohres 10 in das Kunststoffgehäuse 17 begrenzt. Das Einsatzstück 8 ist zusammen mit dem im Kunststoffgehäuse 17 angeordneten Flüssigkeitsverteiler 20 und der mit dem Einsatzstück 8 verspannten Kartusche 5 in einen Grundkörper 44 des Armaturengehäuses 2 eingesetzt; eine entsprechende Darstellung hierzu ergibt sich aus Figur 6.In the outlet opening 23 of the plastic housing 17, the separate water channel 10 is inserted with its inlet-side end in a pressure-tight manner by means of a cylindrical sealing element 22, while on the outlet-side end of the separate water channel 10 an outlet head 18 is also attached in a pressure-tight manner with the aid of a cylindrical sealing element 27 and in a form-fitting manner with the fitting housing 2 is connected. For this purpose, the outlet head 18 - as can be seen in detail in FIG. 5 - has an extension 24 on the inlet side, which is provided with a locking pin 25. The locking pin 25 engages in an opening 26 of the fitting housing 2 and thus ensures a positionally secure fixation of the outlet head 18. The cylindrical sealing element 27 for the pressure-tight connection of the outlet head 18 and separate water channel 10 has an outer annular shoulder 28 which is radial in the receiving bore 35 of the Outlet head 18 abuts and is also provided with an inner annular shoulder 29, which rests with its inner portion 21 on the end face of the separate water channel 10 or on an inserted intermediate piece 30 and with its outer end face 34 strikes a shoulder 33 of the receptacle 35 of the discharge head 18. The bevel 32 on the inlet side of the sealing element 27 in turn makes it easier to place the outlet head on the separate water channel 10. The sealing element 22, with which the inlet-side end of the separate water channel 10 is inserted into the outlet opening 23 of the plastic housing 17, has an analogous configuration to the sealing element 27 at the end of the outlet. The outer annular shoulder 28 of the sealing element 22 lies against the end face 37 or in a recess 38 of the outlet opening 23, while the inner annular shoulder 29 limits the depth of insertion of the outlet pipe 10 into the plastic housing 17. The insert 8 is inserted into a base body 44 of the fitting housing 2 together with the liquid distributor 20 arranged in the plastic housing 17 and the cartridge 5 braced with the insert 8; a corresponding representation of this is shown in FIG. 6.

Die in Figur 7 dargestellte Einlochmischbatterie 1 ist mit einer abnehmbaren Handbrause 39 ausgestattet, die in eine Aufnahme 40 des Armaturengehäuses 2 eingesteckt wird und über eine flexible Verbindungsleitung 41 mit dem zusätzlichen Wasserkanal 10 verbunden ist. Der separate Wasserkanal 10 und die Zulaufrohre 11 sind wiederum in das aus einer Messinglegierung bestehende Einsatzstück 8 druckdicht eingesetzt, wobei im Bereich der Anschlußstellen zusätzliche Dichtelemente 7, wie vorstehend beschrieben, vorgesehen sind. Bei dieser Ausführung der Einlochmischbatterie 1 ist zwischen dem Einsatzstück 8 und der Kartusche 5 ein Belüftungselement 43 mit einer Ventilanordnung vorgesehen. Kartusche 5, Belüftungselement 43 und Einsatzstück 8 sind auf bekannte Weise so miteinander verspannt, daß eine druckdichte Verbindung zwischen den genannten Baugruppen entsteht und die zusätzlichen Dichtelemente 7 an den Anschlußstellen der Zulaufrohre 11 und des separaten Wasserkanals 10 eine flüssigkeitsdichte Verbindung gewährleisten, die jeden Kontakt des durchfließenden Wassers mit dem aus Messing hergestellten Einsatzstück 8 unterbindet.The single-hole mixer tap 1 shown in FIG. 7 is equipped with a removable hand shower 39, which is inserted into a receptacle 40 of the fitting housing 2 and is connected to the additional water channel 10 via a flexible connecting line 41. The separate water channel 10 and the inlet pipes 11 are in turn inserted pressure-tight into the insert 8 consisting of a brass alloy, additional sealing elements 7 being provided in the area of the connection points, as described above. In this embodiment of the single-hole mixer tap 1, a ventilation element 43 with a valve arrangement is provided between the insert 8 and the cartridge 5. Cartridge 5, ventilation element 43 and insert 8 are clamped together in a known manner so that a pressure-tight connection between the mentioned assemblies arises and the additional sealing elements 7 at the connection points of the inlet pipes 11 and the separate water channel 10 ensure a liquid-tight connection which prevents any contact of the flowing water with the insert 8 made of brass.
