carbonated beverages and beer and other viscous edibles such as soups. In addition, other liquids, \\ rie fuel and engine oil, issued in this way will. If the source of liquid to be drawn off is a limited volume in a container, Difficulties arise when the container is empty, as the liquid that is drawn off usually settles in excessively foamed. State. Although this is not a serious drawback for most liquids means there may be a reduction in the taste properties in a sensitive drink such as beer, cause.

There are many systems for dispensing draft beer. One known as the "Tame" system uses that in the United States patent 1 273 021 described "tame" liquid dispenser. In the system, two beer kegs are tapped, and the kegs are connected to the beer tap using a two-way valve tied together. A source of gas, such as pressurized air, is supplied to each keg when it is tapped is. The two-way valve is used to switch from the empty beer keg to the full beer keg. The beer barrels are at a temperature of about 3j5 - 5> 6 ° G (38 - 42 ° F) stored in a cool place. The beer wire from the beer barrel to the "Zahni" valve printed, which is housed in a cooler at a temperature of about 2.2 ° G (36 ° F) near the counter is. When the beer keg is empty, the whole system, namely the lines and the "tame" valve with the Gas filled under pressure. Then a float valve mechanism in the "tame" system is actuated to reduce the air pressure to drain. When a full beer keg is opened, however, the initially tapped beer is through the Presence of air excessively frothy.

In another ciriöFi system, known as the "Golden Gate HooJt-up", become a number of beer kegs below the aforementioned

009835/0043

primary cool storage at a temperature of about 3.3-5.6 ° O (38-42 ° F) and are then connected by a single conduit to a secondary cooler which, as previously described, has a " Tame "valve can be. The same problems ^{noted above for the ll} Tame system exist when using the Golden Gate Hook-up.

Another system has the secondary cooler in one "Golden Gate Hook-up" is either a "Heatex" (registered trademark), or a Tempright "(registered trademark). In these alternative systems a canister is used in which two spirals or coils are arranged one of which contains the coolant and the other contains the beer. The two spirals are in one suitable cooling liquid, for example water, immersed. The entire system is also in this system full of air when the last barrel of beer is empty.

Another system is the "Beer Master" automatic draft beer dispensing system, which is described in the German patent 1 232 84-6. With this automatic pouring system v / grounds use the same secondary coolers as previously described and thus similar ones exist Problems like those that only exist with the "Tame", "Heatex" or "Tempright" systems. So it's time and beer wasted before the system is cleaned of bags containing gas and the pouring of draft beer can take place without excessive foaming.

An object of the invention is to provide an automatic liquid shut-off valve and a gas separator for

009835/0043

. To create liquid drainage lines which have excessive Reduce foaming of the tapped liquids to a minimum

Furthermore, an automatic beer shut-off valve and an air or carbon dioxide gas separator are to be created so that if beer is tapped from the laß under air or carbonic acid gas pressure, excessive foaming of draft beer is kept to a minimum, both when a keg is almost empty and when a full barrel is connected to the tap.

To this end, the invention provides an automatic shut-off valve for a liquid with an inlet channel, a main body portion and an outlet channel in series flow connection, a float cup, the rises from the main body part and communicates with it in such a way that any air or anything Gas entering the valve collects in the Senwimmer cup, an untethered float, the movably arranged in the float cup in the manner is that or when the floating cup with liquid is filled, through which liquid is forced to a first position remote from the outlet channel and thereby allows liquid to flow through the valve and when the liquid cup is emptied of liquid ist5 is moved to a second position in which he has a Connection between the inlet and outlet channels closes, and thereby prevents a flow through the valve, and ■ a guide device which is not connected to the float Guiding the float between the two positions is connected a

In operation, when the beer keg or keg is empty, the gas will enter the float cup under pressure. Venn the gas enters the float cup, the float will sink and the valve will sit up through a Combination τοη lack of buoyancy in the falling ! liquid and the gas pressure that forces the sighting sit up and close the outlet · TTm a better one To effect a seal between the valve head and the valve seat, the needle valve remains closed. Alternatively, excess gas can be pressurized through the Vent opening must be drained. Since the vent is a restricted bore, a whistle will sound to indicate that the keg is empty.

When tapping a new pass, the air pressure is through the needle valve at the top of the beaker is released. When the liquid level in the cup rises, it rises the float up and the beer can from the inlet through the annular inlet channel down through the axial outlet channel and from the radial outlet channel flow from the beer tap. The needle valve is then closed and the gas remaining in the cup is compressed, until a state of equilibrium between this and the level of the beer in the mug is reached as a function of the beer pressure · This automatically creates an e-reserve kinetic energy created to close the valve, when the beer tap is empty.

unscrewed. Grass can then move freely through the whole system stream. To tap a new passport when the combination is used according to the second feature of the invention, namely the combination of the bleeding rod and the automatic shut-off valve, the passport is tapped and the Spigot valve turned on. The air pressure in the keg drives the air down the tap and into the cup of the automatic shut-off valve. If desired, the needle valve can be opened to relieve the air pressure to fill the mug with beer} then the needle valve is closed. On the other hand, the needle valve can be closed stay to build up a reserve of kinetic energy in the compressed air to help shut off the valve when the beer keg is empty. Thus, the float remains in the beer liquid until the beer keg is empty.

When the beer keg is empty the air will enter the valve cup and the float will sink. As soon as that If the float valve is close to the valve seat, the excess air pressure in the valve cup will snap the valve head into the valve seat and the valve will then stay closed. The pressure of the air in the empty tap will create a further sealing effect between the valve and the valve seat.
