Ein Zapfhahn gemäß dem Oberbegriff des Anspruch 1 ist aus US-A-4 742 942 bekannt.A tap according to the preamble of claim 1 is known from US-A-4,742,942.

Bei einem bekannten Zapfhahn der vorgenannten Art (US 2 373 294) weisen sowohl der Hohlzylinder als auch das hülsenförmige Teil äußere Kragen auf, an denen die Feder abgestützt ist. Die Feder liegt somit offen in der Durchflusskammer für das Getränk. Ein solcher Zapfhahn lässt sich wegen eines derartig gestalteten hülsenförmigen Teils und Hohlzylinders mit freiliegender Feder nicht optimal reinigen. Eine bakterielle Verunreinigung ist selbst bei größter Sorgfalt kaum zu vermeiden.In a known tap of the aforementioned type (US 2,373,294), both the hollow cylinder and the sleeve-shaped part on outer collar, where the spring is supported. The spring is thus open in the flow chamber for the drink. Such a nozzle can not be optimally cleaned because of such a shaped sleeve-shaped part and hollow cylinder with exposed spring. A bacterial contamination is difficult to avoid even with the greatest care.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Zapfhahn der eingangs genannten Art einen Ventilkörper zu entwickeln, der einerseits die Erzeugung von Schaum ermöglicht und der andererseits leicht zu reinigen ist.The invention has for its object to develop in a tap of the type mentioned a valve body, on the one hand allows the generation of foam and on the other hand is easy to clean.

Diese Aufgabe wird bei einem Zapfhahn der eingangs genannten Art dadurch gelöst, dass die Feder in einer von dem hülsenförmigen Teil und dem Hohlzylinder gebildeten Ringkammer angeordnet ist, die an beiden Enden von zwischen dem Hohlzylinder und dem hülsenförmigen Teil wirksamen Ringdichtungen abgedichtet ist.This object is achieved in a tap of the type mentioned above in that the spring is arranged in an annular chamber formed by the sleeve-shaped part and the hollow cylinder, which is sealed at both ends of effective between the hollow cylinder and the sleeve-shaped part ring seals.

Die besonderen Vorteile eines solchen Zapfhahns bestehen darin, dass die Feder des Ventilkörpers in einer nach außen abgedichteten Kammer angeordnet ist. Deshalb kann der Ventilkörper ohne Zerlegung in seine Einzelteile optimal gereinigt werden.The particular advantages of such a tap are that the spring of the valve body is disposed in an outwardly sealed chamber. Therefore, the valve body can be optimally cleaned without disassembly into its individual parts.

Nach einer Ausgestaltung der Erfindung ist die Dichtung des Ventilkörpers zwischen einer Stirnseite des federbelasteten Hohlzylinders und einem Kragen des hülsenförmigen Teils angeordnet. Vorzugsweise besteht das hülsenförmige Teil aus zwei axial hintereinander angeordneten Teilen, wobei auf dem dem Ventilsitz näheren Teil an dessen dem ventilsitz abgewandten Ende der nach Art einer Kappe ausgebildete andere Teil sitzt.According to one embodiment of the invention, the seal of the valve body is arranged between an end face of the spring-loaded hollow cylinder and a collar of the sleeve-shaped part.

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 adjustable by a control lever 7, 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 block.

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 engages behind the shaft 13 and the head 14. 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 as 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 acting as a valve seat bearing shell 17a and on the other hand, the rotationally symmetrical body 16 of the control lever 7, which has in its periphery acting as a ventilation bridge recess 19 which connects depending on the tilt position of the control lever 7 said part 4a with a leading into the atmosphere bore 20 in the nozzle 8. Thus, in the closed position of the shut-off valve shown in Fig. 3, the ventilation of the spout 3 is effective, while in the open position of the shut-off valve shown in Fig. 4, 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 tap described is very simple. Compared to the prior 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 snug fit 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 be able to easily clean the funds required for this purpose, the valve body 10 shown enlarged in FIGS. 6 to 9 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 on the sleeve-shaped part 31st against the force of a spring 36 displaceable 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, which between the sleeve-shaped part 31 and the hollow cylinder 37 on one side and the cap-shaped part 32 and the projection 37 of the hollow cylinder 36 on the other side act. 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 blocking position of the shut-off 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 at the Collar 35 lifted seal 11 via the radial bore 42 and the now open space 43 beverage can flow out 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 Durchflusskammer 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, it can be used in any rotational position in the flow chamber.
