Abstract

A keg tap described is for domestic use, and in it an axially shiftable valve-opening rod (3) with a valve-opening element (4) is guided through an essentially cylindrical housing (1) enclosing a pressure space (2) and is inserted through a piston (8) which is arranged in the lower region of the housing (1) and which limits the pressure space (2) located here. The valve-opening rod (3) is at the same time a riser pipe and has a continuous liquid passage (7) which leads outwards from the valve-opening element (4) at one end and which, at the opposite end, merges into a liquid duct (17) cut out in a stirrup (15) arranged essentially at right angles to the liquid passage (7) and equipped with a shut-off valve (19) and with a consequently closable outflow (18). The piston (8) closing off the pressure space (2) is connected via piston rods (14) to a handle (5), by means of which the piston ( 8) is actuated independently of the valve-opening rod (3).

Description

Die Erfindung betrifft einen Keg-Zapfer zum Ausschenken einer Flüssigkeit, insbesondere eines unter Druck stehenden Getränkes, aus einem mit einem Keg-Verschluß versehenen Behälter, bestehend aus einem mit einem Druckerzeugungselement in Verbindung stehenden und einen Druckraum umschließenden Gehäuse, durch das eine mit einem Keg-Verschluß zusammenwirkende, axial bewegbare Ventilöffnungsstange gesteckt ist, die an einem über die Gehäusewand vorstehenden Ende als Ventilöffnungselement gestaltet und an ihrem gegenüberliegenden Ende mit einem Betätigungsteil verbunden ist.The invention relates to a keg dispenser for pouring out a liquid, in particular a pressurized beverage, from a container provided with a keg closure, consisting of a housing connected to a pressure generating element and enclosing a pressure chamber, through which a housing with a keg Closure cooperating, axially movable valve opening rod is inserted, which is designed as a valve opening element at one end projecting above the housing wall and is connected at its opposite end to an actuating part.

Keg-Zapfer werden in der Gastronomie zum Zapfen von Bier aus Fässern verwendet, wobei Zapfköpfe für den Korbfitting und solche für den Flachfitting bekannt sind. Beide Ausführungen bestehen aus einem eine Druckkammer umschließenden Gehäuse, durch das eine hebelbetätigte Ventilöffnungsstange zum Öffnen des Ventils des Keg-Verschlusses gesteckt ist. Der Zapfkopf weist einen Druckgasanschluß und einen Anschluß für einen zum Zapfhahn führenden Schlauch auf. Keg-Zapfer dieser Art sind für den Hausgebrauch nicht geeignet.Keg taps are used in the catering industry for tapping beer from barrels, with tapping heads for basket fitting and those for flat fitting being known. Both versions consist of a housing enclosing a pressure chamber, through which a lever-operated valve opening rod is inserted to open the valve of the keg closure. The tap head has a compressed gas connection and a connection for a hose leading to the tap. Keg dispensers of this type are not suitable for domestic use.

Aus der US-A 4 516 698 ist weiterhin ein Keg-Zapfer zum Ausschenken eines unter Druck stehenden Getränkes aus einem mit einem Keg-Verschluß versehenen Behälter bekannt, der ein mit einem Druckerzeugungselement in Verbindung stehendes und einen Druckraum umschließendes Gehäuse und eine mit einem Keg-Verschluß zusammenwirkende, axial bewegbare Ventilöffnungsstange aufweist, die an einem Ende als Ventilöffnungselement gestaltet und an ihrem gegenüberliegenden Ende mit einem Betätigungsteil verbunden ist.From US-A 4 516 698 a keg dispenser for serving a pressurized beverage from a container provided with a keg closure is also known, which has a housing connected to a pressure generating element and enclosing a pressure chamber and one with a keg Closure has interacting, axially movable valve opening rod, which is designed as a valve opening element at one end and is connected to an actuating part at its opposite end.

Nachteilig bei diesem Stand der Technik ist jedoch, daß zunächst vor Anbringen des Zapfers von Hand der Keg-Verschluß des Behälters geöffnet werden muß.A disadvantage of this prior art, however, is that the keg closure of the container must first be opened by hand before the tap is attached.

Demgegenüber hat sich die vorliegende Erfindung die Aufgabe gestellt, einen derartigen Zapfer dahingehend weiterzuentwickeln, daß nach Anbringen des Zapfers mit Hilfe des Steigrohres der Behälter gleichzeitig angestochen und geöffnet werden kann.In contrast, the present invention has set itself the task of further developing such a tap that after attaching the tap with the help of the riser the container can be pierced and opened at the same time.

Die Lösung dieser Aufgabe gelingt bei einem Keg-Zapfer zum Ausschenken einer unter Druck stehenden Flüssigkeit aus einem mit einem Keg-Verschluß versehenen Behälter, bestehend aus einem einen Druckraum umschließenden Gehäuse, durch das eine mit dem Keg-Verschluß zusammenwirkende axial mit Hilfe eines Griffes bewegbare Ventilöffnungsstange gesteckt ist, die an einem über eine Gehäusewand vorstehenden Ende als Ventilöffnungselement gestaltet und an ihrem gegenüberliegenden Ende mit einem Betätigungsteil verbunden ist, wobei das Gehäuse im wesentlichen zylindrisch ist, und die die gesamte Höhe des Gehäuses durchquerende Ventilöffnungsstange einen durchgehenden, im Ventilöffnungselement nach außen mündenden Flüssigkeitsdurchlauf aufweist, der an seinem gegenüberliegenden Ende in einer hier im wesentlichen im rechten Winkel zum Flüssigkeitsdurchlauf angeordneten Flüssigkeitskanal übergeht, der in einem durch eine Ausnehmung in der Wand des Gehäuses gesteckten Bügel ausgespart ist, und einen mit einem Absperrventil verschließbaren Auslauf für die Flüssigkeit aufweist, bei welchem erfindungsgemäß zwischen dem Griff und der Oberseite des durch das Gehäuse gesteckten Bügels ein Gewindering angeordnet ist, der mit dem Bügel und der Ventilöffnungsstange zusammenwirkt, derart, daß eine Drehbewegung des Gewinderinges den Bügel und die Ventilöffnungsstange hebt bzw. senkt.This problem is solved in a keg tapper for pouring out a pressurized liquid from a container provided with a keg closure, consisting of a housing enclosing a pressure chamber, through which a housing cooperating with the keg closure can be moved axially with the aid of a handle Valve opening rod is inserted, which is designed as a valve opening element at one end projecting over a housing wall and is connected at its opposite end to an actuating part, the housing being essentially cylindrical, and the valve opening rod passing through the entire height of the housing has a continuous, outward opening in the valve opening element has an opening liquid passage, which merges at its opposite end in a liquid channel arranged here essentially at right angles to the liquid passage, in a bend inserted through a recess in the wall of the housing l is recessed, and has an outlet for the liquid which can be closed with a shut-off valve, in which, according to the invention, a threaded ring is arranged between the handle and the upper side of the bracket inserted through the housing, which cooperates with the bracket and the valve opening rod, such that a rotary movement of the threaded ring raises or lowers the bracket and the valve opening rod.

Dadurch wird erreicht, daß nach dem Einsetzen des Zapfers in das Keg-Ventil letzteres durch eine einfache Betätigung des Gewinderinges durchstochen und geöffnet wird, was die Handhabung des Zapfers deutlich vereinfacht.It is thereby achieved that after inserting the tap into the keg valve, the latter is pierced and opened by simply actuating the threaded ring, which considerably simplifies the handling of the tap.

Vorteilhafterweise ist dabei der Druckraum im unteren Bereich des Gehäuseinnenraumes angeordnet und durch einen Kolben begrenzt, der durch Kolbenstangen mit dem Griff am gegenüberliegenden Ende des Gehäuses verbunden ist, und der eine mittige Axialbohrung aufweist, durch die die Ventilöffnungsstange gesteckt und dichtend darin, unabhängig von der Kolbenbewegung, axial verschiebbar ist. Der Kolben ist mit einer Kolbendichtung versehen, die bei Betätigung des Kolbens einen Durchlaß für ein Druckmedium in den Druckraum, im Gehäuse freigibt bzw. schließt. Aus dem Druckraum führt dabei ein mit einem Rückschlagventil versehener Austrittskanal für das Druckmedium.The pressure chamber is advantageously arranged in the lower region of the housing interior and is delimited by a piston which is connected by piston rods to the handle at the opposite end of the housing and which has a central axial bore through which the valve opening rod is inserted and sealed therein, regardless of the Piston movement, is axially displaceable. The piston is provided with a piston seal which, when the piston is actuated, releases or closes a passage for a pressure medium in the pressure chamber, in the housing. An outlet channel with a check valve for the pressure medium leads out of the pressure chamber.

Der Kolben besteht erfindungsgemäß insbesondere aus zwei im Abstand voneinander angeordneten Kolbenscheiben und die Kolbendichtung ist eingesetzt im Zwischenraum zwischen den Kolbenscheiben und liegt an der Innenwand des Gehäuses dichtend an. Bei Betätigen des Kolbens wird ein Durchlaßspalt zwischen dem Gehäuseraum und dem Zwischenraum im Kolben freigegeben bzw. gesperrt. In der dem Druckraum zugekehrten Kolbenscheibe wird durch mindestens eine Bohrung eine Verbindung vom Zwischenraum im Kolben zum Druckraum geschaffen. Letztlich wird vorgeschlagen, daß der Bügel fest mit der Ventilöffnungsstange verbunden und mit dieser axial bewegbar ist.According to the invention, the piston consists in particular of two piston disks which are arranged at a distance from one another, and the piston seal is inserted in the space between the piston disks and lies sealingly against the inner wall of the housing. When the piston is actuated, a passage gap between the housing space and the space in the piston is released or blocked. In the piston disk facing the pressure chamber, a connection from the intermediate space in the piston to the pressure chamber is created through at least one bore. Ultimately, it is proposed that the bracket be firmly connected to the valve opening rod and axially movable with it.

Zusätzlich zum einfacheren Öffnen des Keg-Ventils auftretende Vorteil der geradlinigen Flüssigkeitsführung ohne mehrfache Umlenkung liegt auf der Hand. Der vertikale Flüssigkeitsdurchlauf in der Ventilöffnungsstange innerhalb des Gehäuses wird nur in den ebenfalls geradlinigen horizontalen Flüssigkeitskanal umgelenkt und wird aus diesem in an sich bekannter Weise unmittelbar hinter dem Absperrventil entnommen. Neben herstellungstechnischer Vereinfachung ist ein hygienischer Effekt durch die einfache und sichere Reinigung eines solchen Keg-Zapfers erreicht.In addition to the simpler opening of the keg valve, the advantage of the straight-line liquid flow without multiple deflections is obvious. The vertical liquid flow in the valve opening rod within the housing is deflected only into the likewise straight horizontal liquid channel and is removed from it directly behind the shut-off valve in a manner known per se. In addition to simplifying the manufacturing process, a hygienic effect is achieved by the simple and safe cleaning of such a keg tap.

Die Erfindung wird anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

The invention is explained in more detail using an exemplary embodiment shown in the drawings. Show it:

Der Keg-Zapfer besteht aus einem im wesentlichen zylindrischen Gehäuse 1, durch das eine Ventilöffnungsstange 3 gesteckt ist und die gesamte Länge des Gehäuseinneren durchquert. An dem mit dem Keg-Verschluß im Behälter (nicht dargestellt) zu verbindenden Ende 1a des Gehäuses 1 steht die Ventilöffnungsstange 3 vor und ist hier als Ventilöffnungsstange 3 gestaltet. Das gegenüberliegende Ende der Ventilöffnungsstange 3 wirkt mit einem Betätigungsteil zusammen, das am oberen Ende 1b des Gehäuses angeordnet ist. Bei dem dargestellten Ausführungsbeispiel besteht das Betätigungsteil aus einem Gewindering 21, wie noch näher beschrieben wird.The keg tap consists of an essentially cylindrical housing 1, through which a valve opening rod 3 is inserted and which traverses the entire length of the interior of the housing. At the end 1a of the housing 1 to be connected to the keg closure in the container (not shown), the valve opening rod 3 protrudes and is designed here as a valve opening rod 3. The opposite end of the valve opening rod 3 cooperates with an actuating part which is arranged at the upper end 1b of the housing. In the illustrated embodiment, the actuating part consists of a threaded ring 21, as will be described in more detail.

Durch die Ventilöffnungsstange 3 führt eine durchgehende Axialbohrung, die als Flüssigkeitsdurchlauf 7 gestaltet ist und die Verbindung zwischen einem Steigrohr in dem die Flüssigkeit enthaltenden Behälters (nicht dargestellt) und einem Flüssigkeitskanal 17 schafft, der im wesentlichen in einem rechten Winkel zum Flüssigkeitsdurchlauf 7 angeordnet ist. Dieser Flüssigkeitskanal 17 ist in einem Bügel 15 ausgespart, der durch eine Ausnehmung 16 in der Wand des Gehäuses 1 gesteckt ist und quer durch den Gehäuseraum 6 geht. Der Bügel 15 ist mit einem aus dem Flüssigkeitskanal 17 führenden Auslauf 18 versehen, der sich unmittelbar hinter einem Absperrventil 19 befindet, das durch einen Hebel 20 betätigt wird. Das Zapfen erfolgt hier in bekannter Weise ohne Nachtropfen.Through the valve opening rod 3 there is a continuous axial bore which is designed as a liquid passage 7 and which creates the connection between a riser pipe in the container (not shown) containing the liquid and a liquid channel 17 which is arranged essentially at a right angle to the liquid passage 7. This liquid channel 17 is recessed in a bracket 15 which is inserted through a recess 16 in the wall of the housing 1 and goes across the housing space 6. The bracket 15 is provided with an outlet 18 leading from the liquid channel 17, which is located immediately behind a shut-off valve 19 which is actuated by a lever 20. The tapping takes place here in a known manner without dripping.

Durch diese Anordnung führt ein geradliniger senkrechter Flüssigkeitsdurchlauf 7 durch die Ventilöffnungsstange 3, die somit gleichzeitig als Steigrohr dient und praktisch die geradlinige Verlängerung des in dem Behälterinneren befindlichen Steigrohrs ist. Dieser Flüssigkeitsdurchlauf 7 geht in einen ebenfalls geradlinigen Flüssigkeitskanal 17 über, aus dem das Getränk durch Öffnen des Absperrventils 19 gezapft werden kann.With this arrangement, a straight, vertical liquid passage 7 leads through the valve opening rod 3, which thus simultaneously serves as a riser and is practically the straight extension of the riser located in the interior of the container. This liquid passage 7 merges into a likewise straight-line liquid channel 17, from which the drink can be tapped by opening the shut-off valve 19.

Im unteren Bereich des Gehäuses 1 ist der Druckraum 2 vorgesehen, der von einem Kolben 8 begrenzt ist, durch den Druckmedium, beispielsweise Luft, in den Behälter eingeführt wird. Die Ventilöffnungsstange 3 ist durch eine mittige Axialbohrung in diesem Kolben 8 gleitend geführt und durch eine Dichtung 3a, beispielsweise einen O-Ring, abgedichtet. Der Kolben 8 besteht aus zwei im Abstand voneinander angeordneten Kolbenscheiben 8a, und 8b, die einen Zwischenraum 9 begrenzen, in den ein Dichtelement 11 eingesetzt ist, das bei Betätigen des Kolbens 8 die Zufuhr von Druckmedium bewirkt bzw. sperrt. Die dem Druckraum 2 zugekehrte Kolbenscheibe 8b weist mindestens eine, vorzugsweise jedoch zwei Bohrungen 10 auf, die den Zwischenraum 9 zwischen den Kolbenscheiben 8a und 8b mit dem Druckraum 2 verbinden. Der Kolben 8 ist durch Kolbenstangen 14 mit einem Griff 5 verbunden, der am Ende 1b des Gehäuses 1 angeordnet ist. Durch Axialbewegung dieses Griffes 5 wird der Kolben 8 in Arbeits-bzw. Nichtarbeitsstellung bewegt, wobei das an der Innenwand des Gehäuses 1 anliegende Dichtelement 11 einen Spalt 9a zwischen dem Umfangsrand der oberen Kolbenscheibe 8a und der Innenwand des Gehäuses 1 schließt oder freigibt. Im letztgenannten Fall besteht eine Verbindung zwischen dem Gehäuseraum 6, dem Zwischenraum 9 zwischen den Kolbenscheiben 8a und 8b, dem Durchlaß 10 in der Kolbenscheibe 8b zum Druckraum 2 und von hier zum Austrittskanal 13.In the lower area of the housing 1, the pressure chamber 2 is provided, which is delimited by a piston 8, through which pressure medium, for example air, is introduced into the container. The valve opening rod 3 is through a central Axial bore in this piston 8 slidably and sealed by a seal 3a, for example an O-ring. The piston 8 consists of two piston disks 8a and 8b which are arranged at a distance from one another and which delimit an intermediate space 9 into which a sealing element 11 is inserted, which causes or blocks the supply of pressure medium when the piston 8 is actuated. The piston disk 8b facing the pressure chamber 2 has at least one, but preferably two bores 10, which connect the intermediate space 9 between the piston disks 8a and 8b to the pressure chamber 2. The piston 8 is connected by piston rods 14 to a handle 5 which is arranged at the end 1b of the housing 1. By axially moving this handle 5, the piston 8 is in working or. Moved non-working position, wherein the sealing element 11 abutting the inner wall of the housing 1 closes or releases a gap 9a between the peripheral edge of the upper piston disc 8a and the inner wall of the housing 1. In the latter case, there is a connection between the housing space 6, the intermediate space 9 between the piston disks 8a and 8b, the passage 10 in the piston disk 8b to the pressure chamber 2 and from here to the outlet channel 13.

Zwischen der Unterseite des Griffes 5 und der Oberseite des Bügels 15 ist das Betätigungsteil für die Ventilöffnungsstange 3 angeordnet. Zweckmäßig ist es ein Gewindering 21, der mit dem Bügel 15 und damit mit der Ventilöffnungsstange 3 so verbunden ist, daß bei Drehung des Gewinderinges diese beiden Teile, Bügel 15 und Ventilöffnungsstange 3, gehoben oder gesenkt werden.The actuating part for the valve opening rod 3 is arranged between the underside of the handle 5 and the upper side of the bracket 15. It is expedient to have a threaded ring 21 which is connected to the bracket 15 and thus to the valve opening rod 3 such that these two parts, bracket 15 and valve opening rod 3, are raised or lowered when the threaded ring rotates.

Der Bügel 15 und die Ventilöffnungsstange 3 sind fest miteinander verbunden und zur Stabilisierung durch eine übergreifende Halterung 22 gesichert. Mindestens ein am Bügel 15 vorgesehenes Verbindungsstück 23, von dem in Figur 1 nur ein Teil gezeigt ist greift in eine Umfangssnut 24 am Gewindering 21 ein und gleitet in dieser Nut, wenn der Gewindering gedreht wird.The bracket 15 and the valve opening rod 3 are firmly connected to one another and secured for stabilization by an overlapping bracket 22. At least one connecting piece 23 provided on the bracket 15, of which only one in FIG. 1 The part shown engages in a circumferential groove 24 on the threaded ring 21 and slides in this groove when the threaded ring is rotated.

Durch entsprechendes Drehen des Gewinderinges 21 wird die Ventilöffnungsstange 3 gegen das Ventil im Keg-Verschluß (nicht dargestellt) bewegt und öffnet dieses. Danach wird die Ventilöffnungsstange 3 zum Steigrohr, dessen Flüssigkeitsdurchlauf 7 mit dem Steigrohr im Behälter kommuniziert. Bei Bedarf, das heißt wenn im Behälter Druck aufgebaut werden soll, wird der Griff 5 und damit der Kolben 8 betätigt und das Behälterinnere mit Druckmedium versorgt.By correspondingly turning the threaded ring 21, the valve opening rod 3 is moved against the valve in the keg closure (not shown) and opens it. The valve opening rod 3 then becomes the riser pipe, the liquid passage 7 of which communicates with the riser pipe in the container. If required, that is to say if pressure is to be built up in the container, the handle 5 and thus the piston 8 are actuated and the interior of the container is supplied with pressure medium.

Bei dem erfindungsgemäßen Keg-Zapfer ist die Ventilöffnungsstange 3 durch den darin integrierten Flüssigkeitsdurchlauf 7 gleichzeitig Anstech- und Öffnungselement für den Keg-Verschluß sowie Steigrohr zur Entnahme des Getränkes aus dem Behälter.In the keg tapper according to the invention, the valve opening rod 3 is simultaneously the piercing and opening element for the keg closure and the riser pipe for removing the beverage from the container due to the liquid passage 7 integrated therein.

Als Druckmedium wird vorzugsweise Luft verwendet. Mit geringfügigen, die Merkmale der Konstruktion nicht wesentlich berührenden Änderungen kann der Keg-Zapfer auch für den Gebrauch mit Kohlensäure als Druckmedium ausgelegt werden. In diesem Fall tritt dann anstelle der Kolbenkonstruktion ein entsprechendes Ventil.Air is preferably used as the pressure medium. With minor changes that do not significantly affect the design features, the keg dispenser can also be designed for use with carbon dioxide as a pressure medium. In this case, a corresponding valve is used instead of the piston construction.
