Description

Die Erfindung betrifft einen Zapfhahn für Getränke, insbesondere Biere, mit einem Basiskörper, an dem ein einen Durchflusskanal aufweisendes Anschlussstück vorgesehen ist und an dem eine Ausflusstülle angesetzt ist, wobei im Basiskörper zwischen dem Anschlussstück und der Ausflusstülle ein mittels einer Steuervorrichtung steuerbarer Absperrventilkörper angeordnet ist, der konisch ausgebildet ist und in einem konisch ausgebildeten Durchbruch des Basiskörpers drehbar um eine quer zur Ausflusstülle verlaufende Drehachse gelagert ist, und wobei der Absperrventilkörper einen Verbindungskanal aufweist, der als Außenkanal in die Mantelfläche des Absperrventilkörpers eingetieft ist und in einer Offenstellung der Steuervorrichtung den Durchflusskanal des Anschlussstücks mit der Ausflusstülle verbindet.The invention relates to a tap for drinks, in particular beers, with a base body, on which a flow channel exhibiting a connecting piece is provided and to which an outflow nozzle is attached, wherein in the base body between the connection piece and the Ausflusstülle a controllable by means of a control valve stop valve body is arranged, which is conically formed and is rotatably mounted in a conically formed opening of the base body about an axis extending transversely to the outflow spout, and wherein the check valve body has a connecting channel which is recessed as an outer channel in the lateral surface of the Absperrventilkörpers and in an open position of the control device the flow channel of the Connecting piece with the outlet spout connects.

Ein Zapfhahn dieser Art ist aus der US 2,195,022 bekannt. Der dort beschriebene Zapfhahn weist einen Basiskörper auf, der an seiner Unterseite mit einem einen Durchflusskanal aufweisenden Anschlussstück versehen ist, das an einer zu einem Bierfass führenden Leitung angeschlossen wird. An dem Basiskörper ist ferner seitlich eine Ausflusstülle angesetzt, deren Einlass oberhalb des Anschlussstückes und beabstandet dazu angeordnet ist. Des Weiteren weist der Basiskörper eine Belüftungsbohrung auf, die oberhalb des Einlasses der Ausflusstülle angeordnet ist und an der Oberseite des Basiskörpers mündet. In dem Basiskörper ist zwischen dem Anschlussstück und der Ausflusstülle ein mittels eines Handhebels steuerbarer Absperrventilkörper angeordnet, der konisch ausgebildet ist und in einem konisch ausgebildeten Durchbruch des Basiskörpers drehbar um eine quer zur Ausflusstülle verlaufende Drehachse gelagert ist. Nachteilig bei diesem bekannten Zapfhahn ist, dass trotz seiner Belüftungsbohrung stets eine kleine Restmenge Bier in ihm gefangen bleibt, und zwar im Durchgangskanal des Basiskörpers zwischen dem Einlass der Ausflusstülle und dem an der Unterseite des Basiskörpers angebrachten Anschlussstück. Nach einer längeren Zapfpause beeinträchtigt die im Zapfhahn verbliebene Flüssigkeitsrestmenge die Qualität eines dann neu gezapften Bieres.A tap of this kind is from the US 2,195,022 known. The tap described therein has a base body, which is provided on its underside with a flow channel having a connecting piece, which is connected to a line leading to a beer keg. On the base body, a discharge spout is also attached laterally, the inlet of which is arranged above the connecting piece and at a distance therefrom. Furthermore, the base body has a ventilation bore, which is arranged above the inlet of the outflow nozzle and opens at the top side of the base body. In the base body, a controllable by means of a hand lever check valve body is arranged between the connecting piece and the Ausflusstülle, which is conical and formed in a conically shaped opening of the base body is rotatably mounted about a transverse axis to the Ausflusstülle extending axis of rotation. A disadvantage of this known tap is that despite its vent hole always a small amount of beer remains trapped in him, in the passageway of the base body between the inlet of the Ausflusstülle and attached to the underside of the base body fitting. After a longer Zapfpause the residual liquid remaining in the tap affects the quality of a then newly tapped beer.

Der erfindungsgemäße Zapfhahn ist dadurch gekennzeichnet, dass das an den Basiskörper angesetzte Einlaufende der Ausflusstülle in der Gebrauchsstellung des Zapfhahns unterhalb der Austrittsöffnung des Durchflusskanals des Anschlussstückes angeordnet ist, wobei der Verbindungskanal in der Schließstellung der Steuervorrichtung im Wesentlichen unterhalb der Drehachse des Absperrventilkörpers angeordnet ist, und dass in den Basiskörper zwischen dem Anschlussstück und dem Absperrventilkörper eine ringbuchsenförmige Dichtung eingesetzt ist, die den Durchflusskanal fortsetzt und den Absperrventilkörper ringförmig berührt.The tap according to the invention is characterized in that the attached to the base body inlet end of the outlet spout is disposed in the use position of the tap below the outlet opening of the flow passage of the connecting piece, wherein the connecting channel is arranged in the closed position of the control device substantially below the axis of rotation of the check valve body, and that in the base body between the connector and the check valve body, a ring-sleeve-shaped seal is inserted, which continues the flow channel and the check valve body annularly.

Der erfindungsgemäße Zapfhahn besitzt einen relativ einfachen Aufbau, zeichnet sich in seiner Absperrstellung durch eine besonders zuverlässige Abdichtwirkung aus und lässt sich bei Bedarf sehr einfach reinigen.The tap according to the invention has a relatively simple structure, is characterized in its shut-off by a particularly reliable sealing effect and can be cleaned very easily if necessary.

Denn dadurch, dass der Verbindungskanal als Außenkanal in einen Umfangsabschnitt der Mantelfläche des Absperrventilkörpers eingetieft ist, ist der Verbindungskanal nach der Demontage des Absperrventilkörpers für Reinigungszwecke gut zugänglich.Because the fact that the connecting channel is recessed as an outer channel in a peripheral portion of the lateral surface of the check valve body, the connecting channel after disassembly of the check valve body for cleaning purposes is easily accessible.

Die im Basiskörper angeordnete ringbuchsenförmige Dichtung stellt eine besonders zuverlässige Abdichtwirkung in der Absperrstellung sicher.The arranged in the base body ring-sleeve-shaped seal ensures a particularly reliable sealing in the shut-off.

Dadurch, dass das an den Basiskörper angesetzte Einlaufende der Ausflusstülle in der Gebrauchsstellung des Zapfhahns unterhalb der Austrittsöffnung des Durchflusskanals des Anschlussstückes angeordnet ist, und dadurch, dass der Verbindungskanal in der Schließstellung der Steuervorrichtung im Wesentlichen unterhalb der Drehachse des Absperrventilkörpers angeordnet ist, wird stets eine im Wesentlichen vollständige Selbstentleerung des Verbindungskanals nach Absperrung des Durchflusskanals sichergestellt.Characterized in that the attached to the base body inlet end of the outlet spout is disposed in the use position of the nozzle below the outlet opening of the flow passage of the fitting, and in that the connecting channel is arranged in the closed position of the control device substantially below the axis of rotation of the check valve body, is always a essentially complete self-draining of the connection channel after blocking the flow channel ensured.

In diesem Zusammenhang ist es vorteilhaft, wenn gemäß einer bevorzugten Ausgestaltung in dem Basiskörper eine Belüftungsbohrung ausgebildet ist, die bei abgesperrtem Durchflusskanal mit dem Verbindungskanal des Absperrventilkörpers kommuniziert. Durch die Belüftungsbohrung ist sichergestellt, dass nach Absperren des Durchflusskanals das hinter dem Durchflusskanal, insbesondere in der Ausflusstülle noch befindliche Getränk schnell abfließen kann. Vorzugsweise ist die Belüftungsbohrung dabei so im Basiskörper angeordnet, dass sie in der Absperrstellung des Absperrventilkörpers an der höchstgelegenen Stelle des Verbindungskanals mündet.In this context, it is advantageous if, in accordance with a preferred embodiment, a ventilation bore is formed in the base body, which communicates with the connecting channel of the shut-off valve body when the flow channel is shut off. Through the ventilation hole ensures that after shutting off the flow channel behind the flow channel, in particular in the outflow nozzle still located beverage can drain quickly. Preferably, the ventilation hole is arranged in the base body so that it opens in the shut-off position of the check valve body at the highest point of the connecting channel.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Zapfhahns besteht darin, dass der Basiskörper mit einer federbelasteten Arretierung versehen ist, welche die Steuervorrichtung und/oder den Absperrventilkörper in einer relativ zu dem Durchflusskanal vorgegebenen Drehstellung des Absperrventilkörpers arretiert, in welcher der Verbindungskanal des Absperrventilkörpers mit weniger als 20%, vorzugsweise weniger als 15% der Querschnittsfläche des Durchflusskanals in Überdeckung liegt. Der Durchflusskanal ist in dieser Drehstellung des Absperrventilkörpers nur geringfügig geöffnet, so dass beim Zapfen von unter Druck stehender Flüssigkeit, beispielsweise von Bier, mittels des Absperrventilkörpers Flüssigkeitsschaum erzeugt wird. Die federbelastete Arretierung erleichtert dem Benutzer des Zapfhahns das schnelle Einstellen der für die Schaumerzeugung günstigen Drehstellung des Absperrventilkörpers.A further advantageous embodiment of the tap according to the invention is that the base body is provided with a spring-loaded locking, which locks the control device and / or the check valve body in a predetermined relative to the flow passage rotational position of the check valve body, in which the connecting channel of the check valve body with less than 20 %, preferably less than 15% of the cross-sectional area of the flow channel in overlap. The flow channel is only slightly opened in this rotational position of the check valve body, so that fluid is generated during the tapping of pressurized liquid, such as beer, by means of the check valve body. The spring-loaded lock facilitates the user of the tap to quickly adjust the favorable for the generation of foam rotational position of the check valve body.

Die Steuervorrichtung des erfindungsgemäßen Zapfhahns umfasst nach einer weiteren Ausgestaltung mindestens eine deckelartige Abdeckung, die mit dem Absperrventilkörper lösbar verbunden ist. Vorzugsweise ist der Absperrventilkörper zwischen zwei deckelartigen Abdeckungen angeordnet, die mit dem Absperrventilkörper lösbar verbunden sind, wobei an den Abdeckungen eine U-förmige Halterung formschlüssig angebracht ist, die mit einem Hebel zur Steuerung des Absperrventilkörpers versehen ist.The control device of the tap according to the invention comprises according to a further embodiment, at least one cover-like cover which is detachably connected to the check valve body. Preferably, the check valve body between two cover-like covers is arranged, which are detachably connected to the check valve body, wherein on the covers a U-shaped bracket is positively mounted, which is provided with a lever for controlling the check valve body.

Weitere bevorzugte und vorteilhafte Ausgestaltungen des erfindungsgemäßen Zapfhahns sind in den Unteransprüchen angegeben.Further preferred and advantageous embodiments of the dispensing tap according to the invention are specified in the subclaims.

Die in der Zeichnung dargestellten Zapfhähne sind für Getränke, insbesondere Biere, bestimmt, die in der Regel unter Druck stehen. Der jeweilige Zapfhahn weist einen Basiskörper 1 auf, an dem ein Anschlussstück 2 für eine nicht dargestellte Zufuhrleitung für das zu zapfende Getränk vorgesehen ist, und an dem ferner eine Ausflusstülle 3 angesetzt ist. Das Anschlussstück 2 ist rohrstutzenförmig ausgebildet und weist ein Außengewinde 4 sowie einen gegenüber dem Durchmesser des Außengewindes radial vorstehenden Absatz 5 auf.The taps shown in the drawing are intended for drinks, especially beers, which are usually under pressure. The respective tap has a base body 1, on which a connection piece 2 is provided for a feed line, not shown, for the beverage to be tapped, and to which an outflow nozzle 3 is also attached. The connecting piece 2 is formed pipe-socket-shaped and has an external thread 4 and a relation to the diameter of the external thread radially projecting paragraph 5.

In dem Basiskörper 1 ist ein mittels einer Steuervorrichtung steuerbarer Absperrventilkörper 6 angeordnet. Die Steuervorrichtung umfasst einen Steuerhebel 7, der mit einem über eine Schraubverbindung lösbaren Handgriff 8 versehen ist. Der zwischen dem Anschlussstück 2 und der Ausflusstülle 3 angeordnete Absperrventilkörper 6 ist konisch ausgebildet und in einem entsprechend konisch ausgebildeten Durchbruch 9 des Basiskörpers 1 drehbar gelagert. Es ist zu erkennen, dass die Drehachse des Absperrventilkörpers 6 quer zur Ausflusstülle sowie quer zu dem im Anschlussstück 2 verlaufenden Durchflusskanal 10 verläuft. In der Gebrauchsstellung des Zapfhahns verläuft die Drehachse des Absperrventilkörpers 6 im Wesentlichen horizontal.In the base body 1 a controllable by means of a control valve stop valve body 6 is arranged. The control device comprises a control lever 7, which is provided with a detachable via a screw handle 8. The arranged between the connector 2 and the outlet spout 3 check valve body 6 is conical and in a corresponding conical trained breakthrough 9 of the base body 1 rotatably mounted. It can be seen that the axis of rotation of the check valve body 6 extends transversely to the outflow spout and transversely to the flow passage 10 extending in the connection piece 2. In the use position of the tap, the axis of rotation of the check valve body 6 extends substantially horizontally.

Der Basiskörper 1 umfasst eine dem Anschlussstück 2 zugeordnete Bohrung 11, die quer zu dem konischen Durchbruch 9 verläuft und an demselben mündet. Der Durchmesser der Bohrung 11 ist nach außen hin erweitert, wobei die Erweiterung ein Innengewinde 12 aufweist.The base body 1 comprises a connection 11 associated with the bore 11, which extends transversely to the conical opening 9 and opens at the same. The diameter of the bore 11 is widened outwardly, wherein the extension has an internal thread 12.

In die Bohrung 11 ist eine ringbuchsenförmige Dichtung 13 eingesetzt, die den Durchflusskanal 10 fortsetzt und den Absperrventilkörper 6 ringförmig berührt. Die Form der dem Anschlussstück 2 abgewandten ringförmigen Stirnseite der Dichtung 13 ist an die konische Mantelfläche des Absperrventilkörpers 6 angepasst. Die Dichtung 13 besteht aus einem gummielastischen Material. Sie ist beispielsweise aus einem thermoplastischen Polyurethan-Elastomer gefertigt.In the bore 11, a ring-sleeve-shaped seal 13 is used, which continues the flow channel 10 and the check valve body 6 annularly. The shape of the connecting piece 2 facing away from the annular end face of the seal 13 is adapted to the conical lateral surface of the check valve body 6. The seal 13 is made of a rubber-elastic material. It is made for example of a thermoplastic polyurethane elastomer.

Die Dichtung 13 weist an ihrem dem Anschlussstück 2 zugewandten Ende einen radial nach außen vorspringenden Flansch 14 auf, der an dem durch die Erweiterung der Bohrung 11 bedingten stufenförmigen Absatz 15 formschlüssig anliegt. Zur passgenauen Ausrichtung der Dichtung 13 in Bezug auf die konische Mantelfläche des Absperrventilkörpers 6 weist die Dichtung 13 vorzugsweise mindestens eine Markierung auf, die einem Bezugspunkt oder einer Markierung am Basiskörper 1 zugeordnet ist. Beispielsweise ist in der dem Anschlussstück 2 zugewandten Seite des Flansches 14 der Dichtung 13 eine Ausnehmung 16 ausgebildet, die der vertikalen Längsmittelebene des Zapfhahns bzw. der Längsmittelachse des Steuerhebels 7 oder Handgriffs 8 zugeordnet ist. Durch Ausrichten dieser Ausnehmung 16 auf die vertikale Längsmittelebene des Zapfhahns bzw. die Längsmittelachse des Steuerhebels 7 oder Handgriffs 8 wird sichergestellt, dass die dem Absperrventilkörper 6 zugewandte ringförmige Stirnseite der Dichtung 13 passgenau an die konische Mantelfläche des Absperrventilkörpers 6 angepasst ist. Alternativ zu dieser Ausnehmung bzw. Markierung 16 können die Dichtung 13 und der Basiskörper 1 auch einander zugeordnete Formschlusselemente (nicht gezeigt) zur passgenauen Ausrichtung der Dichtung 13 in Bezug auf die konische Mantelfläche des Absperrventilkörpers 6 aufweisen. Beispielsweise kann hierzu an der ringbuchsenförmigen Dichtung 13 ein radial nach außen vorstehender Vorsprung (nicht gezeigt) angeformt sein und in der Bohrung 11 eine mit Abstand vor dem Durchbruch 9 endende Nut (nicht gezeigt) eingetieft sein, in die der Vorsprung im eingesetzten Zustand der Dichtung 13 formschlüssig eingreift.The seal 13 has at its end facing the connector 2 a radially outwardly projecting flange 14 which rests against the form of the extension of the bore 11 step-shaped shoulder 15. For precise alignment of the seal 13 with respect to the conical lateral surface of the check valve body 6, the seal 13 preferably has at least one mark associated with a reference point or a mark on the base body 1. For example, in the connection piece 2 facing side of Flange 14 of the seal 13 a recess 16 is formed, which is associated with the vertical longitudinal center plane of the tap or the longitudinal center axis of the control lever 7 or handle 8. By aligning this recess 16 on the vertical longitudinal center plane of the tap or the longitudinal center axis of the control lever 7 or handle 8 ensures that the shut-off valve body 6 facing annular end face of the seal 13 is precisely adapted to the conical outer surface of the check valve body 6. As an alternative to this recess or marking 16, the seal 13 and the base body 1 can also have mutually associated positive-locking elements (not shown) for accurately aligning the seal 13 with respect to the conical lateral surface of the check valve body 6. For example, a radially outwardly projecting projection (not shown) may be integrally formed on the annular bushing-shaped seal 13 and be recessed in the bore 11 a groove (not shown) ending at a distance in front of the aperture 9, into which the projection in the inserted state of the seal 13 positively engages.

Das Anschlussstück 2 ist über ein entsprechendes Außengewinde mit dem Innengewinde 12 des Basiskörpers 1 verschraubt. Das dem Absperrventilkörper 6 zugewandte Ende des Anschlussstückes 2 liegt dabei an der Dichtung 13 an und presst letztere mit ihrem Flansch 14 leicht gegen den umlaufenden Absatz 15 der Bohrung 11.The connecting piece 2 is screwed via a corresponding external thread with the internal thread 12 of the base body 1. The shut-off valve body 6 facing the end of the connecting piece 2 rests against the seal 13 and presses the latter with its flange 14 slightly against the peripheral shoulder 15 of the bore eleventh

Die von der ringbuchsenförmigen Dichtung 13 definierte Durchflussöffnung und der vom Anschlussstück 2 definierte Durchflusskanal 10 fluchten miteinander und haben im Wesentlichen den gleichen Innendurchmesser.The flow opening defined by the ring-shaped seal 13 and the flow passage 10 defined by the connection piece 2 are aligned with one another and have substantially the same inside diameter.

Ferner umfasst der Basiskörper 1 eine der Ausflusstülle 3 zugeordnete Bohrung 18, die ebenfalls an dem konischen Durchbruch 9 mündet. Der Durchmesser auch dieser Bohrung 18 ist nach außen hin erweitert, wobei in die Erweiterung die röhrchenförmige Ausflusstülle 3 eingesteckt ist. Die Ausflusstülle 3 und die Bohrung 18 fluchten miteinander und haben im Wesentlichen den gleichen Innendurchmesser.Furthermore, the base body 1 comprises a bore 18 assigned to the outflow spout 3, which also opens at the conical opening 9. The diameter of this bore 18 is also expanded to the outside, wherein in the extension of the tubular Ausflusstülle 3 is inserted. The spout 3 and the bore 18 are aligned with each other and have substantially the same inner diameter.

Die Längsmittelachsen der Bohrungen 11, 18 liegen in der selben Ebene. Sie schließen einen Winkel von ca. 120° ein. Es versteht sich aber, dass die Bohrungen 11, 18 auch anders zueinander angeordnet sein können, so dass der von ihren Längsmittelachsen eingeschlossene Winkel - abweichend von 120° - zum Beispiel ca. 100° oder ca. 130° beträgt.The longitudinal center axes of the bores 11, 18 lie in the same plane. They include an angle of about 120 °. It is understood, however, that the bores 11, 18 can also be arranged differently to one another, so that the angle enclosed by their longitudinal center axes-deviating from 120 °-is for example about 100 ° or about 130 °.

Der Basiskörper 1 besitzt in der Seitenansicht im Wesentlichen eine kreisförmige Außenkontur. Er besteht aus Metall, vorzugsweise aus Edelstahl. Der Absperrventilkörper 6 ist aus einem Material gebildet ist, welches weniger hart ist als das Material des Basiskörpers 1. Vorzugsweise ist der Absperrventilkörper 6 aus Kunststoff, beispielsweise aus Polyoxymethylen (POM) oder aus Polybutylenterephthalat (PBT) gefertigt.The base body 1 has in the side view substantially a circular outer contour. It is made of metal, preferably stainless steel. The shut-off valve body 6 is formed of a material which is less hard than the material of the base body 1. Preferably, the shut-off valve body 6 is made of plastic, for example polyoxymethylene (POM) or polybutylene terephthalate (PBT).

Der Absperrventilkörper 6 ist zwischen zwei deckelartigen Abdeckungen 19, 20 angeordnet, die mit dem Absperrventilkörper 6 lösbar verbunden sind. An den Abdeckungen 19, 20 ist eine gabel- oder U-förmige Halterung 21 formschlüssig angebracht, die mit dem Hebel 7 zur Steuerung des Absperrventilkörpers 6 versehen ist. Am Mitteilteil der U-förmigen Halterung 21 ist ein Gewindebolzen oder eine Schraube 22 angebracht, an dem der Steuerhebel 7 bzw. der Handgriff 8 angeschraubt sind.The check valve body 6 is arranged between two cover-like covers 19, 20, which are detachably connected to the check valve body 6. On the covers 19, 20, a forked or U-shaped bracket 21 is positively mounted, which is provided with the lever 7 for controlling the check valve body 6. At Mitteilteil the U-shaped bracket 21 is a threaded bolt or a screw 22nd attached to which the control lever 7 and the handle 8 are screwed.

Der Basiskörper 1 weist an seinen den Abdeckungen 19, 20 zugewandten Seiten jeweils eine kreisringförmige Vertiefung 23, 24 auf, die den konischen Durchbruch 9 konzentrisch umgeben. Die kreisringförmige Vertiefung 23, 24 bildet einen Absatz mit einer ebenen Ringfläche. Der Abstand der beiden Ringflächen voneinander ist etwas größer als der axiale Abstand seitlicher Stirnflächen 25, 26 des konischen Absperrventilkörpers 6. Der Absperrventilkörper 6 weist zapfenförmige Vorsprünge 27, 28 auf, die gegenüber seinen seitlichen Stirnflächen 25, 26 vorstehen.The base body 1 has at its the covers 19, 20 facing sides in each case an annular recess 23, 24 which surround the conical opening 9 concentric. The annular recess 23, 24 forms a shoulder with a flat annular surface. The distance between the two annular surfaces is slightly larger than the axial distance of lateral end faces 25, 26 of the conical check valve body 6. The check valve body 6 has pin-shaped projections 27, 28 which protrude with respect to its lateral end faces 25, 26.

Die deckelartigen Abdeckungen 19, 20 umfassen einen kugelschichtförmigen Abschnitt und einen damit einstückig verbundenen kreiszylindrischen Abschnitt, der formschlüssig in eine der Vertiefungen 23, 24 des Basiskörpers 1 aufgenommen ist. Der Außendurchmesser des kreiszylindrischen Abschnitts ist kleiner als der größte Außendurchmesser des kugelschichtförmigen Abschnitts.The cover-like covers 19, 20 comprise a spherical-layer-shaped section and a circular cylindrical section integrally connected thereto, which is received in a form-fitting manner in one of the recesses 23, 24 of the base body 1. The outer diameter of the circular cylindrical portion is smaller than the largest outer diameter of the spherical layer-shaped portion.

Jede der beiden Abdeckungen 19, 20 weist eine mittig angeordnete Bohrung 29, 30 auf. In den Bohrungen 29, 30 sind die zapfenförmigen Vorsprünge 27, 28 des Absperrventilkörpers 6 aufgenommen. In den Figuren 10 und 11 ist zu erkennen, dass die zapfenförmigen Vorsprünge 27, 28 unterschiedlich lang sind. Der längere Vorsprung 28 weist eine Gewindebohrung 31 auf.Each of the two covers 19, 20 has a centrally disposed bore 29, 30. In the holes 29, 30, the pin-shaped projections 27, 28 of the check valve body 6 are added. In the Figures 10 and 11 It can be seen that the peg-shaped projections 27, 28 are of different lengths. The longer projection 28 has a threaded bore 31.

Die Abdeckung 19 mit der Bohrung 30, die den kürzeren zapfenförmigen Vorsprung 27 des Absperrventilkörpers 6 aufnimmt, weist eine Gewindebohrung 32 auf. Diese mündet in die Bohrung 30, fluchtet mit einer in dem Vorsprung 27 ausgebildeten Bohrung 33 und besitzt den gleichen Innengewindedurchmesser wie die Gewindebohrung 31.The cover 19 with the bore 30, which receives the shorter pin-shaped projection 27 of the check valve body 6, has a threaded bore 32. This flows into the bore 30, is aligned with a bore 27 formed in the projection 27 and has the same internal thread diameter as the threaded bore 31st

Der jeweilige kugelschichtförmige Abschnitt ist an seiner flachen Außenseite mit einer Nut 34, 35 versehen, in die die Schenkel der gabelförmigen Halterung 21 formschlüssig eingesetzt sind. Die Nuten 34, 35 enden einerseits vor dem konvexen Mantelfläche des kugelschichtförmigen Abschnitts und münden andererseits an ihrem anderen Ende an der konvexen Mantelfläche des kugelschichtförmigen Abschnitts der Abdeckung 19, 20. Das einen Anschlag 36, 37 bildende Ende der jeweiligen Nut 34, 35 ist rund ausgebildet. Die Enden der Schenkel der gabelförmigen Halterung 21 sind dementsprechend abgerundet.The respective spherical layer-shaped portion is provided on its flat outer side with a groove 34, 35, in which the legs of the fork-shaped holder 21 are inserted positively. The grooves 34, 35 terminate on the one hand in front of the convex lateral surface of the spherical layer-shaped portion and on the other hand open at its other end to the convex outer surface of the spherical layer portion of the cover 19, 20. The stop 36, 37 forming end of the respective groove 34, 35 is round educated. The ends of the legs of the fork-shaped holder 21 are rounded accordingly.

Ferner besitzen die Schenkel der Halterung 21 Bohrungen (Durchbrüche) 38, 39, die bei entsprechender Anordnung der Schenkel in den Nuten 34, 35 mit den Gewindebohrungen 31, 32 fluchten.

Daneben ist ein weiterer Stift 45 vorgesehen, der in eine Sacklochbohrung 46 in der seitlichen Stirnfläche des Absperrventilkörpers 6 eingesteckt ist. Die Stifte 44, 45 sind in Sacklochbohrungen eingefügt, die in dem kreiszylindrischen Abschnitt der deckelförmigen Abdeckung 19 ausgebildet sind (Figuren 10 und 11).In addition, a further pin 45 is provided, which is inserted into a blind hole 46 in the lateral end face of the check valve body 6. The pins 44, 45 are inserted into blind holes, which are formed in the circular cylindrical portion of the lid-shaped cover 19 ( Figures 10 and 11 ).

Des Weiteren ist in dem Basiskörper 1 eine Belüftungsbohrung 47 ausgebildet, die nur bei durch den Absperrventilkörper 6 abgesperrtem Durchflusskanal 10 mit dem Verbindungskanal 42 des Absperrventilkörpers 6 kommuniziert. Die Längsmittelachse der Belüftungsbohrung 47 liegt ebenfalls in der Schnittebene der Längsmittelachsen der beiden Bohrungen 11, 18 des Basiskörpers 1.Furthermore, a vent hole 47 is formed in the base body 1, which communicates with the connection channel 42 of the check valve body 6 only when the flow channel 10 is shut off by the check valve body 6. The longitudinal center axis of the ventilation bore 47 is likewise located in the sectional plane of the longitudinal center axes of the two bores 11, 18 of the base body 1.

Die Belüftungsbohrung 47 ist dabei so angeordnet, dass deren Längsmittelachse in der Gebrauchsstellung des Zapfhahns schräg nach unten zum Absperrventilkörper 6 bzw. dessen Verbindungskanal 42 verläuft. Die Längsmittelachse der Belüftungsbohrung 47 und die Längsmittelachse der dem Abschlussstück 2 zugeordneten Bohrung 11 des Basiskörpers 1 schließen somit einen stumpfen Winkel ein.The ventilation hole 47 is arranged so that its longitudinal central axis in the position of use of the tap obliquely down to the check valve body 6 and its connecting channel 42 extends. The longitudinal center axis of the ventilation bore 47 and the longitudinal center axis of the end piece 2 associated bore 11 of the base body 1 thus include an obtuse angle.

In der Schließstellung des Zapfhahns mündet die Belüftungsbohrung 47 an der höchsten Stelle des im Absperrventilkörper 6 ausgebildeten Verbindungskanals 42 (vgl. Figuren 5 und 6).In the closed position of the tap, the vent hole 47 opens at the highest point of the shut-off valve body 6 formed in the connecting channel 42 (see. FIGS. 5 and 6 ).

Des Weiteren ist der Basiskörper 1 mit einer federbelasteten Arretierung versehen. Die Arretierung umfasst einen Arretierkörper 48, der in einer im Basiskörper 1 ausgebildeten Bohrung 49 angeordnet und durch eine in der Bohrung 49 festgelegte Druckfeder 50 belastet ist. Die Bohrung 49 mündet an den beiden seitlichen Ringflächen des Basiskörpers 1, wobei die an den Arretierkörper 48 angrenzende Mündung einen etwas kleineren Durchmesser aufweist als der Arretierkörper 48, so dass dessen abgerundete Stirnseite 51 aus der Bohrung 49 vorsteht, der federbelastete Arretierkörper 48 aber bei einer Demontage der Abdeckungen 19, 20 nicht vollständig aus der Bohrung 49 herausgedrückt wird.Furthermore, the base body 1 is provided with a spring-loaded lock. The lock comprises a locking body 48 which is arranged in a formed in the base body 1 bore 49 and loaded by a defined in the bore 49 compression spring 50. The Bore 49 opens at the two lateral annular surfaces of the base body 1, wherein the adjoining the locking body 48 mouth has a slightly smaller diameter than the locking body 48 so that its rounded end face 51 protrudes from the bore 49, but the spring-loaded locking body 48 during disassembly the covers 19, 20 is not completely pushed out of the bore 49.

Die dem Arretierkörper 48 zugewandte Abdeckung 20 ist mit einer kleinen Vertiefung 52 versehen, in die der Arretierkörper 48 in einer vorgegebenen Drehstellung des Absperrventilkörpers 6 eingreift. Die Drehstellung, in der die Arretierung wirksam wird, ist so gewählt, dass der Verbindungskanal 42 des Absperrventilkörpers 6 mit weniger als 10% der Querschnittsfläche des Durchflusskanals 10 bzw. der Bohrung 11 in Überdeckung liegt. Bezogen auf den Durchmesser der Bohrung 11 bzw. des Durchflusskanals 10 und die Bogenlänge des Verbindungskanals 42 beträgt die Überdeckung beispielsweise weniger als 1,5 mm, vorzugsweise weniger als 1 mm.The locking body 48 facing the cover 20 is provided with a small recess 52, in which the locking body 48 engages in a predetermined rotational position of the check valve body 6. The rotational position in which the locking is effective, is selected so that the connecting channel 42 of the check valve body 6 is less than 10% of the cross-sectional area of the flow channel 10 and the bore 11 in overlap. Based on the diameter of the bore 11 and the flow channel 10 and the arc length of the connecting channel 42, the coverage is for example less than 1.5 mm, preferably less than 1 mm.

In dieser Drehstellung des Absperrventilkörpers 6 strömt das zu zapfende, unter Druck stehende Getränk unter Schaumbildung über den Verbindungskanal 42 in die Ausflusstülle 3. Die Belüftungsbohrung 47 kommuniziert in dieser Drehstellung des Absperrventilkörpers 6 nicht mit dessen Verbindungskanal 42.In this rotational position of the check valve body 6, the pressurized beverage to be tapped flows under foam formation via the connection channel 42 into the outlet nozzle 3. The ventilation bore 47 does not communicate with its connection channel 42 in this rotational position of the stop valve body 6.

Der Absperrventilkörper 6 des erfindungsgemäßen Zapfhahns lässt sich zu Reinigungszwecken leicht demontieren, indem die Schrauben 40, 41 herausgedreht werden und die gabelförmige Halterung 21 aus den Nuten der Abdeckungen 19, 20 herausgezogen wird.The check valve body 6 of the tap according to the invention can be easily disassembled for cleaning purposes by the screws 40, 41 are unscrewed and the forked Holder 21 is pulled out of the grooves of the covers 19, 20.

In den Figuren 12 bis 17 ist ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Zapfhahns dargestellt. Auch bei diesem Ausführungsbeispiel ist in den Basiskörper 1 zwischen dem Anschlussstück 2 und dem Absperrventilkörper 6 eine ringbuchsenförmige Dichtung 13 eingesetzt ist, die den vom Anschlussstück 2 definierten Durchflusskanal 10 fortsetzt und den Absperrventilkörper 6 ringförmig berührt.In the FIGS. 12 to 17 is a further embodiment of a tap according to the invention shown. Also in this embodiment, a ring-socket-shaped seal 13 is inserted into the base body 1 between the connector 2 and the check valve body 6, which continues the flow passage 10 defined by the connector 2 and the stop valve body 6 is annularly contacted.

Die gummielastische Dichtung 13 weist wiederum einen radial nach außen vorspringenden Flansch 14 auf, der an dem durch die Erweiterung der Bohrung 11 bedingten stufenförmigen Absatz 15 formschlüssig anliegt.The rubber-elastic seal 13 in turn has a radially outwardly projecting flange 14 which rests on the conditional by the extension of the bore 11 step-shaped shoulder 15 positively.

In der dem Anschlussstück 2 zugewandten Seite des Flansches 14 sind zwei diametral gegenüberliegende Ausnehmungen bzw. Sacklöcher 16 ausgebildet, die insbesondere der passgenauen Ausrichtung der Dichtung 13 in Bezug auf die konische Mantelfläche des Absperrventilkörpers 6 dienen.In the connection piece 2 facing side of the flange 14, two diametrically opposite recesses or blind holes 16 are formed, which serve in particular the accurate fit orientation of the seal 13 with respect to the conical surface of the check valve body 6.

Der in den Figuren 12 bis 17 dargestellte Zapfhahn unterscheidet sich von dem Zapfhahn gemäß den Figuren 1 bis 11 in der Ausführung der gabelförmigen Halterung 21 sowie deren Befestigung an dem Absperrventilkörper 6. Der konisch ausgebildete Absperrventilkörper 6 ist auch in diesem Fall vorzugsweise aus Kunststoff, beispielsweise aus Polyoxymethylen oder Polybutylenterephthalat gefertigt. Im Unterschied zu dem zuvor beschriebenen Ausführungsbeispiel weist er jedoch eine stabförmige Drehachse 53 aus Metall, vorzugsweise aus Edelstahl auf. Der konische Ventilkörper 6 ist dabei mit der stabförmigen Drehachse 53 reib- und/oder formschlüssig verbunden, beispielweise aufgeschrumpft. In die beiden Enden der stabförmigen Drehachse 53 sind Gewindebohrungen (nicht gezeigt) eingearbeitet.The in the FIGS. 12 to 17 illustrated tap differs from the tap according to the FIGS. 1 to 11 in the embodiment of the fork-shaped holder 21 and its attachment to the shut-off valve body 6. The conical shut-off valve body 6 is preferably made of plastic, for example, polyoxymethylene or polybutylene terephthalate in this case. In contrast to the embodiment described above, however, it has a rod-shaped axis of rotation 53 made of metal, preferably made of stainless steel. The conical valve body 6 is frictionally and / or with the rod-shaped axis of rotation 53 positively connected, for example, shrunk. In the two ends of the rod-shaped axis of rotation 53 threaded holes (not shown) are incorporated.

Der Absperrventilkörper 6 ist wiederum zwischen zwei deckelartigen Abdeckungen 19, 20 angeordnet. Die Abdeckungen 19, 20 weisen mit den Gewindebohrungen der stabförmigen Drehachse 53 fluchtende Bohrungen auf und sind durch Schrauben 40, 41,vorzugsweise Innensechskantschrauben, mit dem Absperrventilkörper 6, und zwar mit dessen stabförmiger Drehachse 53 lösbar verbunden.The check valve body 6 is in turn arranged between two cover-like covers 19, 20. The covers 19, 20 have aligned with the threaded holes of the rod-shaped axis of rotation 53 holes and are connected by screws 40, 41, preferably Allen screws, with the check valve body 6, with its rod-shaped axis of rotation 53 detachably connected.

An den Abdeckungen 19, 20 ist jeweils eine Hälfte 21.1, 21.2 der gabelförmigen Halterung 21 angebracht, wobei die beiden Hälften miteinander durch den als Hebel dienenden Griff 8 zur Steuerung des Absperrventilkörpers 6 verbunden sind. Die jeweilige Halterungshälfte 21.1, 21.2 ist einstückig mit der zugeordneten Abdeckung 19 bzw. 20 verbunden bzw. an dieser angeformt. Die Abdeckungen 19, 20 und die Halterung 21 sind beispielsweise aus Kunststoff gefertigt und mit einem metallischen Überzug versehen.On the covers 19, 20 are each a half 21.1, 21.2 of the fork-shaped holder 21 is mounted, wherein the two halves are connected to each other by the serving as a lever handle 8 for controlling the check valve body 6. The respective holder half 21.1, 21.2 is integrally connected to the associated cover 19 or 20 or formed on this. The covers 19, 20 and the holder 21 are made for example of plastic and provided with a metallic coating.
