Description

Die Erfindung betrifft eine Zapfvorrichtung, insbesondere für ein Bierfaß, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a dispensing device, in particular for a beer barrel, according to the preamble of claim 1.

Aus DE 195 40 542 A1 ist ein Bierfaß mit einer integrierten Zapfvorrichtung bekannt, die in der Mantelfläche des Bierfasses im unteren Bereich des Fasses angeordnet ist. Die Zapfvorrichtung besteht im wesentlichen aus einem hohlzylindrischen Außenteil und einem in dem Außenteil axial verschiebbaren, ebenfalls hohlzylindrischen Innenteil, wobei das Außenteil durch eine Öffnung in der Mantelfläche des Bierfasses in das Bierfaß hineinragt und an den Umfangsrändern des Loches fest mit der Wandung des Bierfasses verbunden ist, um das Loch abzudichten. Das hohlzylindrische Außenteil der Zapfvorrichtung weist in seiner Mantelfläche eine Öffnung auf, durch die Bier in das Innere des Außenteils eintreten kann. Das ebenfalls hohlzylindrische Innenteil weist dagegen an seinem außenliegenden Ende im Bereich der Mantelfläche unten eine Austrittsöffnung auf, durch die Bier gezapft werden kann, wobei die innenliegende Stirnseite des hohlzylindrischen Innenteils frei ist, um ein Eintreten von Bier aus dem hohlzylindrischen Außenteil in das Innenteil zu ermöglichen. Bei der Lagerung und beim Transport dieses Bierfasses ist das Innenteil vollständig in das Außenteil hineingeschoben. Zum einen schließt die Zapfvorrichtung hierbei an ihrer Außenseite nahezu bündig mit der Mantelfläche des Bierfasses ab, so daß eine Beschädigung der Zapfvorrichtung beim Transport weitgehend ausgeschlossen ist. Zum anderen wird die Öffnung in der Mantelfläche des hohlzylindrischen Außenteils in diesem Zustand durch die Mantelfläche des hohlzylindrischen Innenteils abgedeckt, so daß kein Bier aus dem Faß austreten kann. Zum Zapfen wird dann das hohlzylindrische Innenteil mittels eines an der äußeren Stirnseite des Innenteils angeformten Griffs axial herausgezogen. Das Bier fließt durch die Öffnung in der Mantelfläche des Außenteils, dann durch die offene innere Stirnseite des Innenteils und wird anschließend über die Austrittsöffnung in der Mantelfläche des Innenteils abgegeben.Out DE 195 40 542 A1 is a beer keg with an integrated tap known, which is located in the outer surface of the beer keg in the lower part of the barrel. The dispensing device consists essentially of a hollow cylindrical outer part and an axially displaceable in the outer part, also hollow cylindrical inner part, wherein the outer part protrudes through an opening in the lateral surface of the beer barrel in the beer barrel and is connected to the peripheral edges of the hole fixed to the wall of the beer barrel to seal the hole. The hollow cylindrical outer part of the dispensing device has in its lateral surface an opening through which beer can enter into the interior of the outer part. The likewise hollow cylindrical inner part, however, has at its outer end in the region of the lateral surface below an outlet opening through which beer can be tapped, the inner end face of the hollow cylindrical inner part is free to allow entry of beer from the hollow cylindrical outer part in the inner part , When storing and transporting this beer keg, the inner part is pushed completely into the outer part. On the one hand, the dispensing device almost closes on its outside flush with the lateral surface of the beer keg, so that damage to the dispensing device during transport is largely excluded. On the other hand, the opening in the lateral surface of the hollow cylindrical outer part is covered in this state by the lateral surface of the hollow cylindrical inner part, so that no beer can escape from the barrel. To pin the hollow cylindrical inner part is then pulled axially by means of an integrally formed on the outer end side of the inner part handle. The beer flows through the opening in the outer surface of the outer part, then through the open inner end face of the inner part and is then discharged through the outlet opening in the lateral surface of the inner part.

Das vorstehend beschriebene, bekannte Bierfaß mit der integrierten Zapfvorrichtung ermöglicht zwar einen sofortigen Zapfbeginn ohne eine vorherige manuelle Installation, nachteilig bei der bekannten Zapfvorrichtung ist jedoch, daß Innenteil und Außenteil eine Preßpassung bilden, um eine hinreichende Dichtwirkung zu erzielen, wodurch die axiale Verschiebung des Innenteils nur mit einem relativ großen Kraftaufwand möglich ist. Insbesondere bei einem weitgehend geleerten und entsprechend leichten Bierfaß kann dies zu einem Umkippen des Bierfasses führen bzw. ein Festhalten des Bierfasses erforderlich machen.Although the above-described, known beer keg with the integrated tap allows an immediate Zapfbeginn without prior manual installation, disadvantageous in the known tapping device is that the inner part and outer part form a press fit to achieve a sufficient sealing effect, whereby the axial displacement of the inner part only possible with a relatively large effort. Especially with a largely emptied and correspondingly light beer keg, this can lead to a tipping over of the beer keg or make it necessary to hold the beer keg.

Aus der DE 554131 ist ein Rohrschieberzapfhahn bekannt, bei welchem ein in einem fest stehenden Aussenrohr gegen Drehung gesichertes Innenrohr ausziehbar angeordnet ist. Zwischen dem Außenrohr und dem Schieber sind keine zusätzlichen Dichtungen vorgesehen, vielmehr weist der Schieber am Aussenende des Innenrohres ein um dessen Achse lose drehbares Griffstück auf, das unter Zwischenschaltung einer Dichtungsscheibe bei eingeschobenem Schieber nach dem Anschrauben eine Abdichtung gewährleisten kann.From the DE 554131 a pipe pusher tap is known in which a fixed in a fixed outer tube against rotation inner tube is arranged extendable. Between the outer tube and the slide no additional seals are provided, but rather the slide at the outer end of the inner tube on the axis of a loosely rotatable handle, which can ensure a seal with the interposition of a sealing washer with inserted slide after screwing.

Der Erfindung liegt die Aufgabe zugrunde, eine Dichtung für eine Zapfvorrichtung bereitzustellen.The invention has for its object to provide a seal for a dispensing device.

Die Aufgabe wird - ausgehend von der bekannten Zapfvorrichtung, dadurch gelöst, dass zwischen dem Innenteil und dem Außenteil mindestens eine Dichtung angeordnet ist und dass mindestens eine Dichtung im Bereich der Durchflußöffnung des Außenteils ausgebildet ist.The object is - starting from the known dispensing device, solved in that between the inner part and the outer part at least one seal is arranged and that at least one seal in the region of the flow opening of the outer part is formed.

In einer Variante der Erfindung ist die Zapfvorrichtung zweiteilig mit einem hohlzylindrischen Außenteil und einem hohlzylindrischen Innenteil aufgebaut, wobei das hohlzylindrische Innenteil um seine Längsachse gedreht werden kann, um entsprechende Öffnungen in den Mantelflächen von Innenteil und Außenteil mehr oder weniger in Deckung zu bringen und damit den Flüssigkeitsstrom zu steuern. Die Öffnungen im Außenteil und Innenteil weisen hierbei jeweils eine besondere Form auf, um beim Verdrehen ein feinfühliges Dosieren des Flüssigkeitsstroms zu ermöglichen. So weist mindestens eine der beiden Öffnungen in Außenteil und Innenteil eine in Richtung der jeweils anderen Öffnung abnehmende Breite auf, um beim Öffnen eine gleichmäßige Zunahme des Flüssigkeitsstroms zu erreichen, da der Flüssigkeitsstrom von der Größe der in Deckung übereinanderliegenden Öffnungsflächen abhängt. So können die Öffnungen beispielsweise dreiecksförmig ausgebildet sein, wobei die Spitzen der Dreiecke jeweils der anderen Öffnung zugewandt sind.In a variant of the invention, the dispensing device is constructed in two parts with a hollow cylindrical outer part and a hollow cylindrical inner part, wherein the hollow cylindrical inner part can be rotated about its longitudinal axis to bring corresponding openings in the lateral surfaces of the inner part and outer part more or less to coincide and thus the To control fluid flow. The openings in the outer part and inner part in this case each have a special shape to allow for twisting a sensitive dosing of the liquid flow. Thus, at least one of the two openings in the outer part and inner part in the direction of each decreasing width on the other opening to achieve a uniform increase in the liquid flow when opening, since the liquid flow depends on the size of the overlapping opening surfaces in overlap. Thus, the openings may be formed, for example, triangular, with the tips of the triangles are each facing the other opening.

Bei einer vorteilhaften Ausführungsform kann zwischen dem Innenteil und dem Außenteil mindestens eine Dichtung angeordnet sein. Dabei ist es günstig, wenn die mindestens eine Dichtung im Bereich der Durchflußöffnung des Außenteils ausgebildet ist.In an advantageous embodiment, at least one seal can be arranged between the inner part and the outer part. It is advantageous if the at least one seal is formed in the region of the flow opening of the outer part.

Bei einer Variante der Ausführungsformen kann es günstig sein, daß vor und/oderhinter der jeweiligen Durchflußöffnung um das Innenteil je ein Dichtungsring angeordnet ist. Dadurch wird verhindert, daß Flüssigkeit in den Spalt zwischen Innenteil und Außenteil eintritt und durch die Durchflußöffnung zum Ventil gelangen kann, insbesondere dann, wenn vor und hinter der Durchflußöffnung des Außenteils die Dichtungsringe in einer Ringnut im Außenteil festliegen.In a variant of the embodiments, it may be favorable that a respective sealing ring is arranged before and / or behind the respective flow opening around the inner part. This prevents liquid from entering the gap between the inner part and the outer part and passing through the flow opening to the valve, in particular when the sealing rings are fixed in an annular groove in the outer part in front of and behind the flow opening of the outer part.

Vorteilhaft kann sein, daß die Dichtung als eine die Durchflußöffnung in der Wand des Außenteils umgebende Manschette ausgebildet ist, die in dem Spalt zwischen dem Innen- und dem Außenteil einen Dichtwulst entlang des Außenumfangs der Durchflußöffnung aufweist. Hierdurch kann bei einer Ausführungsform, bei der das Außenteil an seinem in das Faß ragende Ende verschlossen ist, die Abdichtung gegen Eintreten von Flüssigkeit in den Innenkanal des Innenteils bei hineingeschobenem Innenteil sicher gewährleistet werden.It may be advantageous that the seal is formed as a sleeve surrounding the flow opening in the wall of the outer part, which has a sealing bead along the outer periphery of the flow opening in the gap between the inner and the outer part. In this way, in an embodiment in which the outer part is closed at its end projecting into the barrel, the seal against ingress of liquid into the inner channel of the inner part with the inner part pushed in can be reliably ensured.

Dabei kann es günstig sein, daß der Dichtwulst in Richtung des Faßinneren als Dichtfläche ausgebildet ist, wobei vorteilhafterweise die Öffnung für den Durchfluß in dem Außenrohr als Langloch ausgebildet ist, in welchem der Dichtwulst eingespritzt ist. In einer solchen Ausbildung weist das Dichtungsmaterial die eigentliche Durchflußöffnung durch das Außenteil hindurch auf. Dabei ist es sinnvoll, daß die flächige Ausdehnung etwas mehr als die lichte Weiter der Durchflußöffnung des Innenteils beträgt. Hierdurch wird sichergestellt, daß auch bei teilweiser oder beginnender Überlappung der jeweiligen Durchflußöffnungen eine Abdichtung gegen den Zwischenspalt zwischen dem Innen- und dem Außenteil gewährleistet ist.It may be advantageous that the sealing bead is formed in the direction of the drum interior as a sealing surface, wherein advantageously the opening for the flow in the outer tube is formed as a slot in which the sealing bead is injected. In such an embodiment, the sealing material has the actual flow opening through the outer part through. It makes sense that the areal extent is slightly more than the clear Next of the flow opening of the inner part. This ensures that even with partial or incipient overlap of the respective flow openings a seal against the intermediate gap between the inner and the outer part is ensured.

Vorteilhafterweise besteht die Dichtung aus elastischem, spritzfähigem Material. Besonders günstig kann es sein, daß die Dichtung für die Durchflußöffnung in dem Außenteil einstückig mit der Abschlußdichtung zwischen Zapfer und Faß ausgebildet ist, wobei die Abschlußdichtung an das Außenteil angespritzt ist.Advantageously, the seal consists of elastic, sprayable material. Especially It may be favorable that the seal for the flow opening in the outer part is formed integrally with the sealing seal between Zapfer and barrel, wherein the sealing seal is molded onto the outer part.

Bei einer besonders vorteilhaften Ausführungsform sind Mittel zum lösbaren Festsetzen des Innenteils in der Betriebsstellung vorgesehen, d.h. in derjenigen Stellung, in der die Durchflußöffnungen des Innen- und des Außenteils im wesentlichen fluchten.In a particularly advantageous embodiment means are provided for releasably locking the inner part in the operating position, i. in the position in which the flow openings of the inner and the outer part are substantially aligned.

Dabei können vorteilhafterweise die Begrenzungsmittel als Mittel zum lösbaren Festsetzen ausgebildet sein. Hierbei ist es günstig, wenn eine Rastausnehmung am Innenteil ausgebildet ist, in die eine am Außenteil angeordnete federnde Rastnase lösbar eingreift. Durch die Verwendung der Begrenzungseinrichtung als Mittel zum Festsetzen können besondere Arretierungsmittel eingespart werden, die erforderlich sind, das Innenteil in der Betriebsposition, in der sich die Durchflußöffnungen in Deckung befinden, festzuhalten. Vorteilhafterweise ist die Rastnase an einem federnden Element angeformt, das einstückig am Außenteil angeformt ist. Hierbei kann das federnde Element unter Druck der das Außenteil umschließenden Gummidichtung in die Betriebsposition gedrängt sein, so daß die Federkraft sowohl aus dem Material herrührt, aus dem das federnde Element erstellt ist, als auch aus der Flexibilität des Dichtungsmaterials.In this case, advantageously, the limiting means may be formed as a means for releasably setting. It is advantageous if a latching recess is formed on the inner part, in which a spring arranged on the outer latching lug detachably engages. By using the limiting means as a means for setting special locking means can be saved, which are required to hold the inner part in the operating position in which the flow openings are in cover. Advantageously, the locking lug is formed on a resilient element which is integrally formed on the outer part. Here, the resilient element may be urged under pressure of the outer part enclosing the rubber seal in the operating position, so that the spring force originates both from the material from which the resilient element is created, as well as from the flexibility of the sealing material.

Die erfindungsgemäße Zapfvorrichtung ist nicht auf die Verwendung bei Bierfässern beschränkt, sondern läßt sich auch mit anderen Flüssigkeitsbehältern einsetzen. Entscheidend ist lediglich, daß die Zapfvorrichtung in der Wandung des Flüssigkeitsbehälters vormontiert wird, so daß eine Flüssigkeitsentnahme ohne vorherige Installationsarbeiten möglich ist.The dispensing device according to the invention is not limited to use in beer kegs, but can also be used with other liquid containers. It is only crucial that the dispensing device is pre-assembled in the wall of the liquid container, so that a liquid removal is possible without previous installation work.

Auch ist zu bemerken, daß Außenteil und Innenteil nicht notwendigerweise zylindrisch ausgeführt sein müssen. So können diese Bauteile beispielsweise auch einen rechteckigen Querschnitt aufweisen oder dreieckig sein, wodurch auch eine Verdrehung des Innenteils in dem Außenteil verhindert wird.It should also be noted that the outer part and inner part do not necessarily have to be cylindrical. For example, these components can also have a rectangular cross-section or be triangular, whereby rotation of the inner part in the outer part is also prevented.

Andere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet bzw. werden nachstehend zusammen mit der Beschreibung der bevorzugten Ausführung der Erfindung anhand der Figuren dargestellt. Es zeigen:

In Fig. 1 ist ein Bereich einer Zapfvorrichtung im Schnitt dargestellt.In Fig. 1 an area of a tap is shown in section.

Bei dieser Ausführungsform ist das Außenteil 2 mit einer Dichtung 60 im Bereich der Durchflußöffnungen 61 bzw. 61' zwischen dem Außenteil 2 und dem Innenteil 5 ausgestattet. Diese Dichtung ist hier einstückig mit dem Dichtungselement 3 ausgebildet, das zwischen dem Außenteil 2 und dem Umfangsrand der Öffnung in der Wandung 1 des Faßes angeordnet ist. Das Dichtungsmaterial besteht in diesem Fall aus elastischem, spritzfähigem Material.In this embodiment, the outer part 2 is provided with a seal 60 in the region of the flow openings 61 and 61 'between the outer part 2 and the inner part 5. This seal is here formed integrally with the sealing element 3, which is arranged between the outer part 2 and the peripheral edge of the opening in the wall 1 of the barrel. The sealing material in this case consists of elastic, sprayable material.

Bei dem in Fig. 3 und 4 dargestellten alternativen Ausführungsbeispiel ist die Dichtung 60 als ein separates Teil ausgebildet, das in ein Langloch 70 im Außenteil 2 eingesetzt ist. Die Dichtung weist zum Innenteil 5 hin einen Dichtwulst 63 auf, der geringfügig größer ist als der Spalt 64 zwischen dem Innenteil 5 und dem Außenteil 2. Das Langloch erstreckt sich in Richtung Faßinnere, wobei die Dichtung 60 einen Bereich 72 aufweist, der ausreichend groß ist, um die Durchflußöffnung 61' im Innenteil 2 vollständig abzudecken, wenn diese sich während des Herausziehens des Innenteils kurz vor dem Überlappen mit der Durchflußöffnung 61 im Außenteil 2 auf dieser Dichtung befindet. Die Dichtung 60 ist als Manschette 62 ausgebildet, d.h. auch an der Außenseite des Außenteils 2 ist ein wulstartiger Rand an der Dichtung 60 ausgebildet, so daß die Dichtung 60 in das Langloch 70 einknöpfbar ist. Durch diese Ausbildung wird sichergestellt, daß ein Eindringen von Bier in den Spalt 64 während der beginnenden Überlappung der beiden Öffnungen 61 und 61' nicht stattfindet, so daß ein Austreten von Bier zwischen den verschiebbaren Teilen 2 und 5 vermieden wird.At the in Fig. 3 and 4 illustrated alternative embodiment, the seal 60 is formed as a separate part which is inserted into a slot 70 in the outer part 2. The seal has towards the inner part 5 toward a sealing bead 63 which is slightly larger than the gap 64 between the inner part 5 and the outer part 2. The slot extends in the direction Faßinnere, wherein the seal 60 has a portion 72 which is sufficiently large in order to completely cover the flow opening 61 'in the inner part 2, when it is located on the outer part 2 on this seal during the extraction of the inner part just before overlapping with the flow opening 61 in the outer part 2. The seal 60 is formed as a sleeve 62, that is, on the outer side of the outer part 2, a bead-like edge is formed on the seal 60, so that the seal 60 in the slot 70 is buttoned. This design ensures that beer will enter the gap 64 during incipient overlap the two openings 61 and 61 'does not take place, so that leakage of beer between the displaceable parts 2 and 5 is avoided.

Bei der in Fig. 2 dargestellten Ausführungsform besteht die Dichtung 60 aus einem Satz Dichtringen 60' und 60", wobei der Dichtring 60' in einer entsprechenden Nut 73 im Außenteil 2 und der Dichtring 60" in einer entsprechenden Nut in dem Innenteil 5 eingesetzt ist. Auch dieses Material kann sowohl als separates Teil oder aber bei der Herstellung der jeweiligen Teile mitangespritzt sein. Bei einer derartigen Dichtringanordnung, d.h. wenn zwischen der Durchflußöffnung 61 im Innenteil 5 und dem faßseitigen Ende dieses Innenteils ein Dichtring 73' angeordnet ist, kann das Außenteil 2 am faßseitigen Ende offen bleiben.At the in Fig. 2 In the embodiment shown, the seal 60 consists of a set of sealing rings 60 'and 60 ", the sealing ring 60' being inserted in a corresponding groove 73 in the outer part 2 and the sealing ring 60" in a corresponding groove in the inner part 5. This material can be mitangespritzt both as a separate part or in the production of the respective parts. In such a sealing ring arrangement, that is, if between the flow opening 61 in the inner part 5 and the barrel-side end of this inner part, a sealing ring 73 'is arranged, the outer part 2 remain open at the barrel end.

In Fig. 1 ist auch ein weiteres Ausführungsbeispiel einer Begrenzungseinrichtung dargestellt, die den Weg des Innenteils beim Herausziehen begrenzt. Wie bereits in Verbindung mit Fig. 1a beschrieben, kann in dem Innenteil eine Nut 7 und an dem Außenteil eine Feder 6 angeformt sein. Es sei darauf hingewiesen, daß die Nut 7 dann nicht zwingend erforderlich ist, wenn das Innenteil 5 einen von einem Kreisquerschnitt verschiedenen Querschnitt besitzt, so daß die Verdrehsicherheit bereits durch die äußere Form sichergestellt ist. Bei einem weiteren Ausführungsbeispiel kann statt der Nut 7 lediglich eine Rastausnehmung 66 vorgesehen sein, in die eine am Außenteil angeordnete federnde Rastnase 67 lösbar eingreift. Bei dem in Fig. 11 dargestellten Ausführungsbeispiel ist die federnde Rastnase im vorderen Bereich des Außenteils 2 in unmittelbarer Nachbarschaft der Faßwand 1 einstückig an einem federnden Element 28 angeformt, das seinerseits integral am Außenteil ausgeformt ist. Dadurch, daß das federnde Element 28 im vorderen Bereich des Außenteils 2 ausgebildet ist, kann die das Außenteil umschließende Gummidichtung 3 soweit vorgezogen werden, daß sie das federnde Element und somit die Rastnase nach innen drückt und mit zusätzlicher Federkraft die Rastnase in der Ausnehmung 67 hält. An der Rastnase 67 wie auch an der Rastausnehmung 66 können die Kanten und Flächen so gestaltet sein, daß zwar eine deutliche und merkbare Arretierung herbeigeführt wird, daß jedoch auch unter Aufwendung eines bestimmten Drucks das Innenteil wieder aus der Betriebsposition in die Schließ- oder Ruheposition, in der keine Flüssigkeit gezapft wird, verbracht werden kann.In Fig. 1 is also another embodiment of a limiting device shown, which limits the path of the inner part when pulling out. As already in connection with Fig. 1a described, in the inner part of a groove 7 and on the outer part of a spring 6 may be formed. It should be noted that the groove 7 is then not mandatory if the inner part 5 has a different cross section of a circular cross-section, so that the security against rotation is already ensured by the outer shape. In a further embodiment, instead of the groove 7, only a latching recess 66 may be provided into which a spring-loaded latching nose 67 arranged on the outer part removably engages. In the embodiment shown in Fig. 11, the resilient detent in the front region of the outer part 2 in the immediate vicinity of the drum wall 1 is integrally formed on a resilient member 28, which in turn is integrally formed on the outer part. Characterized in that the resilient member 28 is formed in the front region of the outer part 2, the outer part enclosing the rubber seal 3 can be advanced so far that it pushes the resilient member and thus the latch inwards and holds the locking lug in the recess 67 with additional spring force , At the locking lug 67 as well as at the recess 66, the edges and surfaces can be designed so that, although a significant and noticeable locking is brought about, but that the inner part again under the application of a certain pressure from the operating position to the closed or rest position, in which no liquid is tapped, can be spent.

An dem faßseitigen Ende des Innenteils 5 ist eine Auflauframpe 69 für die in den lichten Querschnitt des Außenteils, d.h. in den Hohlrand 4, hineinragende Rastnase 67 angeformt.At the barrel-side end of the inner part 5 is a ramp 69 for the in the clear Cross-section of the outer part, ie formed in the hollow edge 4, projecting locking lug 67.

Die Erfindung beschränkt sich in ihrer Ausführung nicht auf die vorstehend angegebenen bevorzugten Ausführungsbeispiele. Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch machen.The invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants are conceivable, which make use of the illustrated solution even with fundamentally different types of execution.
