'76 7 Ve/ /ru United States Patent EXTRAQTGR F93 KEG Hans .lorgen Veistrup, Giostrup, Denrsmk, assignor to (Iarisberg Bryggerierne Filed June 4, i964, Ser. No. 372,696 Ciairns priority, application Denmark, June 8, 1963,
2 Claims. (Cl. 22240i}.7)
The invention relates to an extractor for dispensing liquid from a keg under the influence of gas pressure and of the type defined in the introductory clause of claim It.
Such extractors are used specifically for ear kegs and preferably for kegs which are supplied by the brewery with built-inextractor, in which case the user needs only insert the spigot in the extractor in order to open the keg for dispensing the beer under the influence of carbon dioxide pressure. Such casks are returned to the brewery when empty and must be cleansed thoroughly before being re-filled. It is therefore of the greatest significance for the breweries that the extractor can be easily dismantled, that the component parts are formed so that they can be cleaned rapidly and effectively and that an effective seal of the keg is provided both before and after dispensing.
It is the object of the present invention to provide an extractor that meets these requirements, and this object has been achieved by constructing the extractor as defined in the characterizing clause of claim ll.
By using a solid valve body corners and cavities which are difficult to clean are avoided, and the specific design of the valve seats in connection with the shape of the sealing ring obviates twisting of the latter, because it is sandwiched in between two valve seats which are diametrically opposed in relation to the cross-section of the ring.
A preferred embodiment of the extractor according to the invention is defined in claim 2 and the specific advantage thereof is the retaining of the sealing ring on the valve body during the movement thereof until it is separated from the valve body by contact with the fixed seat and then engages the valve seat located on the dispensing tube of the spigot.
The invention is explained here with reference to the drawing, in which FIG. 1 presents an axial section of an extractor according to the invention, and
FIG. 2 shows the valve body on a larger scale and viewed in side elevation.
FIG. 1 shows a cover 1 of a keg (not shown). The cover 1 is provided a downwardly extending flange socket 2 to which an extractor cup 4 is secured by means of bayonet clutch 3, the extractor cup having a larger diameter than the socket 2 whereby a passageway 5 is provided between the socket and the cup.
The lower end of the flange socket 2 is formed as a valve seat 6 of quarter-circular cross-section supporting a sealing ring 7 of circular cross-section and held against a quarter-circular valve seat 8 of a valve body 9, which is urged upwards by means of a spring 16 disposed within the extractor cup 4 and extending downwards into the extractor tube 11 extending from the cup and having a constriction 12 which supports the spring 10.
The extractor cup 4, moreover, is designed to form a quarter-circular valve seat 13 disposed co-axially with the valve seat 8 on the valve body 9 but around the latter.
When the extractor is to be opened, the spigot 14 is inserted into the extractor. The spigot is provided with a projection 15 which together with recesses 16 in the cover 1 forms a bayonet lock which at the insertion of the spigot 14 into the cover 1 causes an axial displacei atented Nov. 3%, 1965 ment of a dispensing tube 117 formed as an extension of the spigot. The dispensing tube is provided at the bottom with one or several grooves 18 above which there is an annular shoulder 19 with a quarter-circular valve seat 20.
The spigot, moreover, has a sealing ring 21 fitting in the flange socket 2, and when the spigot from the position shown in the drawing is pushed downwards into the extractor under the influence of the bayonet lock 15, 16, the lower end of the dispensing tube 17 will engage the upper part of the valve body 9 and urge the valve body downwards against the action of the spring 10. It appears from FIG. 2 that the valve seat 8 is formed to extend slightly more than a quarter-circle and so that at the largest diameter it touches a plane at right angles to the axis of the valve body, while its smallest diameter is slightly less than the diameter at the upper edge 8a. Thus the valve body will retain the sealing ring 7 during the initial part of the downward movement until the sealing ring contacts the valve seat 13 and is separated from the valve body. During the continued downward movement the valve seat 2i) will contact the sealing ring 7, whereby a passageway will be provided for the beer up through the tube ll, the extractor cup 4, between the sealing ring 7 and the valve body 9 through the opening 18 and into the dispensing tube 17. At the same time passage is provided for carbon dioxide from a pipe branch 22, through a carbon dioxide pipe 23 in the spigot round the shoulder 19 and past the lower edge of the flange socket 2, on which the carbon dioxide may pass through the space 5 into the cask above the beer or liquid contained therein.
What I claim is:
it. An extractor for dispensing liquid from kegs under the influence of gas pressure comprising a spring-actuated valve body, which in inactivated position, i.e. the normal position, in cooperation with a sealing ring closes the access to the key, and which by means of a spigot provided with a slidable dispensing tube can be moved against the action of a spring into a position in which passage is provided for gas into the space above the liquid level and for the liquid from the keg, the sealing ring being simultaneously displaced to a position in which it blocks the two passages relatively to one another, wherein the valve body is solid and provided with a seat for the sealing ring, the seat having approximately quarter-circular cross-section, and the sealing ring having a circular cross-section, and that in the portion of the extractor which is connected to the keg a seat is provided, the cross-section of which is positioned diametrically opposite the cross-section of the valve seat relatively to the cross-section of the packing ring, and that below the packing ring in its normal position and spaced therefrom there is a fixed valve seat disposed outside the valve body, while the dispensing tube of the spigot above its lower end containing the dispensing opening is provided with a seat that is co-axial with and symmetrically disposed relatively to the seat of the valve body.
2. An extractor according to claim 1, characterized in that the seat of the valve body is so located that its largest circumference approximately is tangential to a plane at right angles to the direction of movement of the Valve body, and that its smallest circumference is located slightly below its upper edge.
