Abstract

A supply of beer drawn from a cask is delivered through a tap with a flow passage (4) in which the flow is regulated by a lever (7) operated valve (6). The lever moves on a bearing which also functions as an air bleed slide valve (16, 17a, 19, 20). The air bleed valve only opens when the main tap valve (6) is closed.

Description

Die Erfindung betrifft einen Zapfhahn für Getränke, insbesondere Biere, mit einem eine Durchflusskammer aufweisenden Basiskörper, an dessen einem Ende ein an eine Zufuhrleitung für das zu zapfende Getränk anschließbares Anschlussstück vorgesehen ist und an dessen anderem Ende eine Ausflusstülle angesetzt ist, wobei in der zwischen dem Anschlussstück und der Ausflusstülle liegenden Durchflusskammer ein Absperrventil mit einem Ventilsitz und einem in der Durchflusskammer axial verschiebbar gelagerten Ventilkörper angeordnet ist, der mittels eines im Basiskörper verschwenkbar gelagerten Steuerhebels verstellbar ist, und mit einer durch den Steuerhebel bei geschlossenem Absperrventil zu öffnenden Belüftung der Ausflusstülle.The invention relates to a tap for drinks, in particular beers, with a base body having a flow chamber, at one end of which is provided to a supply line for the beverage to be taped connection piece and at the other end of an outlet spout is attached, wherein in between the Connecting piece and the outflow nozzle lying flow chamber a shut-off valve is arranged with a valve seat and an axially displaceably mounted in the flow chamber valve body which is adjustable by means of a pivotably mounted in the base body control lever, and with a by the control lever with the shut-off valve to open ventilation of the spout.

Eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist zum Beispiel aus DE 75 07 121 U bekannt.An apparatus according to the preamble of claim 1 is for example off DE 75 07 121 U known.

Bei Zapfhähnen für Getränke mit einer in Fließrichtung des Getränks hinter einem Absperrventil angeordneten Ausflusstülle besteht das Problem, dass nach Schließen des Absperrventils das hinter dem Absperrventil insbesondere in der Ausflusstülle noch befindliche Getränk nicht ohne weiteres schnell abfließt. Deshalb ist bei einem bekannten Zapfhahn der eingangs genannten Art ( DE 42 07 390 C1 ) eine Belüftung der Ausflusstülle vorgesehen- Die Belüftung besteht darin, dass der Ventilkörper des Absperrventils und ein Kolbenschieber, der in einem vorderen Zylinderabschnitt des Basiskörpers mit flüssigkeitsdichter Passsitzführung verschiebbar gelagert ist, ein Bauteil bilden. Der Kolbenschieber wird bei Schließen des Absperrventils in eine Position verstellt, in der eine in ihm angeordnete Belüftungsbrücke einen von der Ausflusstülle ausgehenden Belüftungskanal mit der Außenatmosphäre verbindet, so dass ein sich in der Ausflusstülle befindliches Getränk hinterlüftet und so schnell abfließen kann. Dieses Hinterlüften der Ausflusstülle wird erkauft mit einem recht komplizierten Aufbau der für die Belüftung vorgesehenen Mittel, nämlich Belüftungskanal, Kolbenschieber und Zylinderabschnitt mit flüssigkeitsdichter Passsitzführung für den Schieberkolben. Dieser komplizierte Aufbau der Belüftung ist aber nicht nur nachteilig wegen der aufwendigen Fertigung seiner Teile, sondern auch aus hygienischen Gründen, da diese Mittel sich nur mit Mühe reinigen lassen. Eine bakterielle verunreinigung ist selbst bei größter Sorgfalt kaum zu vermeiden.When dispensing taps for drinks with an outflow nozzle arranged behind a shut-off valve in the flow direction of the beverage, there is the problem that after closing the shut-off valve, the drink still remaining behind the shut-off valve, in particular in the outflow spout, does not readily drain away quickly. Therefore, in a known tap of the type mentioned ( DE 42 07 390 C1 ) provided a ventilation of the spout - the ventilation is that the Valve body of the shut-off valve and a spool, which is slidably mounted in a front cylinder portion of the base body with liquid-tight fitting seat guide, form a component. When closing the shut-off valve, the spool valve is adjusted to a position in which a ventilation bridge arranged in it connects a ventilation duct emanating from the outflow spout to the outside atmosphere, so that a beverage located in the outflow spout can be ventilated and flowed off so quickly. This back ventilation of the spout is purchased with a rather complicated structure of the means provided for the ventilation, namely ventilation duct, spool and cylinder section with liquid-tight fit guide for the spool. This complicated construction of the ventilation is not only disadvantageous because of the elaborate production of its parts, but also for hygienic reasons, since these agents can be cleaned only with difficulty. Bacterial contamination is difficult to avoid, even with the greatest care.

Bei einem andersartigen Zapfhahn für Getränke ( CH 8981 ) mit einem eine Durchflusskammer aufweisenden Basiskörper und einer Ausflusstülle sowie einem Absperrventil mit einem Ventilkörper, ist der Ventilkörpers als Ausflusstülle ausgebildet. Der Ventilkörper ist außerdem als Drehschieber für verschiedene Drehstellungen ausgebildet. In einer ersten Stellung gibt er den Ausfluss von der Durchflusskammer frei, während er in einer zweiten Stellung die Durchflusskammer absperrt und die Ausflusstülle zu einer Belüftungsöffnung öffnet.For a different type of beer tap ( CH 8981 ) with a flow body having a base body and an outlet spout and a shut-off valve with a valve body, the valve body is formed as a spout. The valve body is also designed as a rotary valve for different rotational positions. In a first position it releases the outflow from the flow chamber, while in a second position it shuts off the flow chamber and opens the discharge spout to a vent opening.

Der Erfindung liegt die Aufgabe zugrunde, einen Zapfhahn für Getränke der eingangs genannten Art zu schaffen, der einfach im Aufbau und leicht zu reinigen ist.The invention has for its object to provide a tap for drinks of the type mentioned, which is simple in construction and easy to clean.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das zur Durchflusskammer offene Verschwenklager des Steuerhebels als Belüftungsventil ausgebildet ist, das nur bei geschlossenem Absperrventil geöffnet ist.This object is achieved in that the open to flow chamber swivel bearing of the control lever is designed as a vent valve, which is open only when the shut-off valve is closed.

Bei dem erfindungsgemäßen Zapfhahn sind die Mittel zur Belüftung der Ausflusstülle auf ein Minimum begrenzt, weil das Belüftungsventil im Schwenklager des Steuerhebels integriert ist. Nach der Montage des den Ventilkörper umfassenden Steuerhebels lässt dieser sich problemlos reinigen und auch die Durchflusskammer leicht durchspülen.In the tap according to the invention, the means for ventilating the spout are kept to a minimum, because the vent valve is integrated in the pivot bearing of the control lever. After mounting the valve body comprehensive control lever can be cleaned easily and easily rinse through the flow chamber.

Vorzugsweise ist das Belüftungsventil als Drehschieberventil ausgebildet. Dabei kann der Drehschieber als ein rotationssymmetrischer Körper mit einer in seiner Peripherie vorgesehenen Belüftungsbrücke ausgebildet sein, mit der sein Ventilsitz zwischen der Durchflusskammer und der Außenatmosphäre überbrückbar ist.Preferably, the vent valve is designed as a rotary valve. In this case, the rotary valve may be formed as a rotationally symmetrical body with a ventilation bridge provided in its periphery, with which its valve seat between the flow chamber and the outside atmosphere can be bridged.

Der rotationssymmetrische Körper ist vorzugsweise als Zylinder oder noch besser als Kugel ausgebildet.The rotationally symmetrical body is preferably designed as a cylinder or even better as a ball.

Wie schon bekannt, ist der Ventilkörper des Absperrventils mit dem als Kipphebel ausgebildeten Steuerhebel über ein Kniegelenk gekuppelt. In weiterer Ausgestaltung kann das Kniegelenk aus einer vom Kipphebel getragenen Gabel und einem vom Ventilkörper getragenen Schaft mit Kopf bestehen, der von der Gabel um- und hintergriffen wird.As already known, the valve body of the shut-off valve is coupled to the control lever designed as a rocker arm via a knee joint. In a further embodiment, the knee joint can be carried by a fork carried by the rocker arm and by a valve body Shaft with head, which is the fork and behind engaged.

Der Zapfhahn für Getränke, insbesondere Biere, die in der Regel unter Druck stehen, weist einen Basiskörper 1 auf, an dessen einem Ende ein Anschlussstück 2 für eine nicht dargestellte Zufuhrleitung für das zu zapfende Getränk vorgesehen ist, und an dessen anderem Ende eine Ausflusstülle 3 angesetzt ist. Das Anschlussstück 2 umschließt zwischen Anschlussstück 2 und Ausflusstülle 3 eine Durchflusskammer 4, die stirnseitig durch einen Stopfen 5 verschlossen ist. In der Durchflusskammer 4 ist ein Absperrventil 6 angeordnet. Das Absperrventil 6 ist durch einen Steuerhebel 7 verstellbar, der an einem Stutzen 8 des Basiskörpers 1 lösbar befestigt und in Richtung des Doppelpfeils 9 verschwenkbar ist, um mit dem Absperrventil 6 den Durchfluss des Getränks zu öffnen oder zu sperren.The tap for drinks, especially beers, which are usually under pressure, has a base body 1, at one end of a connector 2 is provided for a supply line, not shown for the beverage to be tapped, and at the other end of an outlet 3 is scheduled. The connecting piece 2 encloses between connecting piece 2 and outflow nozzle 3 a flow chamber 4, which is closed at the end by a plug 5. In the flow chamber 4, a shut-off valve 6 is arranged. The shut-off valve 6 is through a control lever 7 adjustable, which is releasably attached to a nozzle 8 of the base body 1 and pivotable in the direction of the double arrow 9 to open the flow rate of the beverage with the stop valve 6 or to lock.

Das Absperrventil 6 weist einen in der Durchflusskammer 4 axial verschiebbaren Ventilkörper 10 mit einer Dichtung 11 auf, dem am Ende der Durchflusskammer 4 ein Ventilsitz 12 zugeordnet ist. Der Ventilkörper 10 trägt einen der Dichtung 11 vorgelagerten und bis in den Bereich des Steuerhebels 7 ragenden Schaft 13 mit einem Kopf 14- Der Steuerhebel 5 trägt eine Gabel 15, die den Schaft 13 um- und den Kopf 14 hintergreift. So bildet der Schaft 13 mit der Gabel 14 des Steuerhebels 7 ein Kniegelenk. Gleichzeitig wird durch diese Art der Kupplung der Steuerhebel 7 in einer bestimmten Drehstellung gehalten.The shut-off valve 6 has an axially displaceable in the flow chamber 4 valve body 10 with a seal 11, which is associated with a valve seat 12 at the end of the flow chamber 4. The valve body 10 carries a seal 11 upstream and projecting into the region of the control lever 7 shaft 13 with a head 14- The control lever 5 carries a fork 15, which reverses the shaft 13 and the head 14 engages behind. Thus, the shaft 13 forms a knee joint with the fork 14 of the control lever 7. At the same time the control lever 7 is held in a certain rotational position by this type of clutch.

Der Steuerhebel 7 weist als Verschwenklager einen rotationssymmetrischen Körper 16, insbesondere einen Kugelkopf, und entsprechend geformte Lagerschalen 17a, 17b auf, so dass er in Richtung des Doppelpfeils 9 verschwenkbar ist. In diesen Lagerschalen 17a, 17b wird der rotationssymmetrische Körper 16 durch eine Überwurfmutter 18 gehalten, die auf dem Stutzen 8 des Basiskörpers 1 aufgeschraubt ist.The control lever 7 has a swivel bearing a rotationally symmetrical body 16, in particular a ball head, and correspondingly shaped bearing shells 17 a, 17 b, so that it is pivotable in the direction of the double arrow 9. In these bearing shells 17a, 17b, the rotationally symmetrical body 16 is held by a union nut 18 which is screwed onto the neck 8 of the base body 1.

Zur Belüftung des in Durchflussrichtung des Getränks hinter dem Absperrventil 6 liegenden Teils 4a der Durchflusskammer 4 und damit auch der Ausflusstülle 3 dient ein vom Steuerhebel 7 betätigbares Belüftungsventil. Dieses Belüftungsventil besteht zum einen aus der als Ventilsitz wirkenden Lagerschale 17a und zum anderen dem rotationssymmetrischen Körper 16 des Steuerhebels 7, der in seiner Peripherie eine als Belüftungsbrücke wirkende Ausnehmung 19 hat, die je nach Kippstellung des Steuerhebels 7 den genannten Teil 4a mit einer in die Atmosphäre führenden Bohrung 20 im Stutzen 8 verbindet. So ist in der in Fig, 3 dargestellten geschlossenen Stellung des Absperrventils die Belüftung der Ausflusstülle 3 wirksam, während in der in Fig. 4 dargestellten geöffneten Stellung des Absperrventils die Belüftung gesperrt ist.For ventilation of lying in the direction of flow of the beverage behind the shut-off valve 6 part 4a of the flow chamber 4 and thus also the outflow nozzle 3 is an operable by the control lever 7 vent valve. This vent valve consists on the one hand of the bearing seat 17a acting as a valve seat and on the other hand, the rotationally symmetrical body 16 of the control lever 7, the in its periphery has a recess acting as a ventilation bridge 19 which connects depending on the tilting position of the control lever 7 said part 4a with a leading into the atmosphere bore 20 in the nozzle 8. So is in the in Fig. 3 illustrated closed position of the shut-off valve, the ventilation of the spout 3 effectively while in the in Fig. 4 illustrated open position of the shut-off valve, the ventilation is locked.

Der Aufbau des beschriebenen Zapfhahns ist denkbar einfach. Im Vergleich zum Stand der Technik ist das immer notwendige Verschwenklager gleichzeitig Teil des Belüftungsventils für die Ausflusstülle. Nicht länger wird ein zusätzliches Ventil mit Kolbenschieber in einem mit Passsitz ausgestalteten Zylinderraum benötigt, dessen Dichtigkeit nur mit großem Fertigungsaufwand zu erreichen ist und der nur mit viel Aufwand und meistens nur unzureichend zu reinigen ist.The construction of the described tap is very simple. Compared to the state of the art, the always necessary swivel bearing is at the same time part of the ventilation valve for the outlet spout. No longer is an additional valve with spool required in a snugly designed cylinder chamber, the tightness can only be achieved with great manufacturing effort and is only with great effort and mostly insufficient to clean.

Um bei Bier als Getränk Schaum zu erzeugen, ist es bekannt, nur eine geringe Menge Bier unter Druck durchzulassen. Um die dafür erforderlichen Mittel leicht reinigen zu können, hat der in den Figuren 6 bis 9 vergrößert dargestellte ventilkörper 10 eine besondere Ausgestaltung. Der Schaft 13 ist entgegen der Fließrichtung des Getränks um ein erstes Teil 31 verlängert, das als Hülse ausgebildet ist und einen Durchflusskanal 32 umfasst. Auf diesem Teil 31 ist als zweites Teil 33 eine Kappe mit einem zentralen Kanal 34 aufgeschraubt. Zwischen einem Kragen 35 des Schaftes 13 und einer Stirnseite eines auf dem hülsenförmigen Teil 31 gegen die Kraft einer Feder 36 verschiebbaren Hohlzylinders 37 ist die Dichtung 11 des Absperrventils 6 angeordnet. Der Hohlzylinder 37 übergreift mit einem Ansatz 38 den kappenförmigen Teil 33. Die Feder 36 ist in einem Raum 39 angeordnet, der durch O-Ringdichtungen 40, 41 abgedichtet ist, die zwischen dem hülsenförmigen Teil 31 und dem Hohlzylinder 37 auf der einen Seite und dem kappenförmigen Teil 32 und dem Ansatz 37 des Hohlzylinders 36 auf der anderen Seite wirken. Mindestens eine Radialbohrung 42 verbindet den Durchflusskanal 32 des hülsenförmigen Teils 31 mit dem Raum 43, in dem die Dichtung 11 angeordnet ist.In order to produce beer as a drink foam, it is known to pass only a small amount of beer under pressure. In order to easily clean the funds required for this, has in the FIGS. 6 to 9 enlarged illustrated valve body 10 has a special design. The shaft 13 is extended counter to the flow direction of the beverage by a first part 31, which is formed as a sleeve and comprises a flow channel 32. On this part 31, a cap with a central channel 34 is screwed as a second part 33. Between a collar 35 of the shaft 13 and an end face of a displaceable on the sleeve-shaped part 31 against the force of a spring 36, the hollow cylinder 37, the seal 11 of the shut-off valve 6 is arranged. The hollow cylinder 37 engages with a projection 38, the cap-shaped part 33. The spring 36 is disposed in a space 39 which is sealed by O-ring seals 40, 41 is that act between the sleeve-shaped part 31 and the hollow cylinder 37 on one side and the cap-shaped part 32 and the neck 37 of the hollow cylinder 36 on the other side. At least one radial bore 42 connects the flow channel 32 of the sleeve-shaped part 31 with the space 43 in which the seal 11 is arranged.

Die Funktion dieses Ventilkörpers 10 für die Schaumbildung ist folgende: Bei nicht betätigtem Steuerhebel 7 befindet sich der Ventilkörper 10 mit seiner Dichtung 11 in Anlage an den Ventilsitz 12 und sperrt somit den Durchfluss. Durch Verschwenken des Steuerhebels 7 in der Zeichnung nach links wird das Absperrventil 6 geöffnet. Das Getränk kann seitlich am Ventilkörper 10 vorbeifließen. Durch die Feder 36 bleibt sowohl in der Sperrstellung des Absperrventils 6 als auch in dessen Offenstellung die Dichtung 11 eingeklemmt zwischen dem Kragen 35 des Schaftes 13 und der Stirnseite des Hohlzylinders 37. Dadurch bleibt die Radialbohrung 42 gesperrt. Wird der Steuerhebel 7 aber nach rechts bewegt, dann wird bei am Ventilsitz 12 abgestützter Dichtung 11 der hülsenförmige Teil 31 mit dem kappenförmigen Teil 33 unter Spannung der Feder 36 nach links bewegt. Die am Ventilsitz 12 abgestützte Dichtung 11 mit dem Hohlzylinder 37 verschiebt sich auf dem hülsenförmigen Teil 31, so dass ein Spalt 44 zwischen dem Kragen 35 und der Dichtung 11 entsteht. Das hat zur Folge, dass bei vom Kragen 35 abgehobener Dichtung 11 über die Radialbohrung 42 und den nun offenen Raum 43 Getränk in geringer Menge ausströmen kann- Im Falle von Bier wird dadurch Schaum gebildet,The function of this valve body 10 for the foaming is the following: When not actuated control lever 7, the valve body 10 is with its seal 11 in abutment against the valve seat 12 and thus blocks the flow. By pivoting the control lever 7 in the drawing to the left, the shut-off valve 6 is opened. The beverage can flow past the valve body 10 laterally. By the spring 36 remains both in the locked position of the check valve 6 and in its open position, the seal 11 clamped between the collar 35 of the shaft 13 and the end face of the hollow cylinder 37. This leaves the radial bore 42 is locked. However, if the control lever 7 is moved to the right, then, with the seal 11 supported on the valve seat 12, the sleeve-shaped part 31 with the cap-shaped part 33 is moved under tension of the spring 36 to the left. The supported on the valve seat 12 seal 11 with the hollow cylinder 37 moves on the sleeve-shaped part 31, so that a gap 44 between the collar 35 and the seal 11 is formed. This has the consequence that when lifted from the collar 35 seal 11 via the radial bore 42 and the now open space 43 can flow out beverage in small quantities - In the case of beer foam is formed,

Die besonderen Vorteile dieses Ventilkörpers 10 bestehen darin, dass die Kammer 39 mit der Feder 36 nach außen abgedichtet ist. Deshalb ist seine Reinigung einfach. Wegen der besonderen Kupplung über das Kniegelenk kann er in jeder Drehstellung in die burchflusskammer eingesetzt werden.The particular advantages of this valve body 10 are that the chamber 39 is sealed with the spring 36 to the outside. That's why its easy to clean. Because of The special coupling via the knee joint can be used in any rotational position in the flow-through chamber.
