Beer printing device. Patented in the German Empire on August 7, 1903.

In order to prevent that when the beer is served, z. B. during the night, the beer line leading to the dispensing point remains filled with beer, you have it open the pressure of the pressure medium (the compressed air, carbonic acid etc.) that weighs down on the beer in the keg used to immediately after shutdown of the bar the in the beer line to push the beer back into the keg.

ίο For this purpose you don't have the space above the liquid level in the barrel alone, but also the beer line in the vicinity of the tap with a pressure medium supply line connected, so that the pressure in the barrel holding the column of liquid in the beer line is caused by the pressure at the end the pressure acting on the beer line in the vicinity of the filling tap is kept in equilibrium and therefore the column of liquid in the beer line as a result of its own Severity falls behind.

However, the just identified facilities have the disadvantage that the beer line falling back into the barrel reaches the lower part of the same and here causes the yeast to stir so that the beer is poured again when it is poured again appears cloudy and impure.

Another disadvantage of the marked devices is likely to be found in that the keg must always be removed to clean the beer line, so that through cleaning agents (water or steam) that have been fed into the beer line from the tap the beer line can be led into the open atmosphere, so you do the cleaning the beer line only after removal of the relevant barrel respectively. Carry out emptying of the same can.

The mentioned disadvantages of the previous devices are due to the subject of the present invention through the use of a special bypass line avoided which by a check valve with the beer line and by a second Check valve or an ordinary tap with the housing of the tap in Connection is so that the beer from the beer line is not in the lower, but passes through the bypass line and the housing of the tap into the uppermost part of the barrel, where there is a stir the yeast particles stored on the bottom of the barrel cannot and gradually Removal of that bypass line, the lower part of the beer line with the free atmosphere can be contacted for cleaning without the need to remove the drum.

An example embodiment of the inventive concept just identified is shown schematically on the accompanying drawing.

As the drawing shows, 1 is the beer keg, which is passed through the beer line 2, 3, 4 is connected to the tap 5. 6 is a carbonic acid container, which through valve 7 and line 8 with the pressure vessel 9 in connection

commitment. From the latter, the pressure line ίο goes out, which communicates once through valve ii with line 19, the other time through valve 12 with the beer line 4, 3, 2. Part 2 of the beer line extends through the housing of the tap 13 to the lower part of the vessel I. Between parts 2 and 3 of the beer line .can a sight glass or. a viewing vessel 14 provided with a transparent wall with the three-way cock 15 attached to it at the bottom, on the housing of which the check valve 16 is arranged laterally. The latter is connected through line 17 with the check valve 18 opening into the housing of the tap 13, while the check valve 2J receiving the line 19 opens at the opposite point of the housing. In part 2 of the beer

ao line, the check valve 22 is switched on, which, as indicated by arrow 23, to allow the passage of the beer upwards, but prevents it from downwards. The check valves 18, 27 allow the beer or beer to pass through. the pressure medium in the direction of arrows 25,26.

The mode of operation of the beer pressure apparatus is as follows:

During the duration of the bar, during which the tap 12 is closed and the tap 11 is open, the Carbonic acid pressure through valve 7, line 8, pressure vessel 9, line 10, valve 11, line 19, check valve 27 and the housing of the tap 13 above the level of the im Barrel ι located beer and pushes the same through part 2 of the beer line, check valve 22, three-way tap 15, sight glass 14 and parts 3, 4 of the beer line to the tap 5. However, as soon as the serving of beer is interrupted, tap 12 is opened, whereupon the carbonic acid pressure in line 10 on the upper part of the in the ßierleitung located liquid presses and has the consequence that the same under the Influence of their gravity through part 3 of the beer line, check valve ιό, line 17, Check valve 18 and the housing of the tap 13 in the upper part of the barrel falls behind.

To clean the beer line using water or steam, it is not necessary to to remove the beer barrel, rather it is sufficient to give the chick of the Dreivveghahnes 15 one To give a position that the connection between 2 and 3 is interrupted, between 14 and 16, however, remains, then line 17 by unscrewing the union nuts 20, 21 to remove, whereupon the cleaning agent (water or steam) supplied through the tap 5 at 16 with the dirt particles can be discharged into the open atmosphere.

The arrows 24, 25 and 26 show the direction of flow through the valves 16, 18 and 27.

It goes without saying that instead of carbonic acid pressure, any other pressure, e.g. B. can use the pressure of a compressed gas, in particular compressed air, in which case the carbon dioxide bottle would have to be replaced by a compressed air tank or an air pump. Furthermore, you can instead of the taps 11, 12, 15 and other closing organs, such. B. use shut-off valves, slide valves and the like, in particular replace the two taps 11, 12 with a three-way tap. Similarly, one can turn an ordinary faucet instead of the check \ ^r entils 18, the latter what then before removing the bypass line 17 is to be closed.

Claims (1)

Patent claim: Beer pressure device in which the line supplying the pressure medium is not only with the space above the liquid level in the barrel, but also after actuation of a closing organ with the upper part of the beer line can be connected, characterized by a bypass line 17, which through check valve 16 with the beer line, and through check valve 18 or a ordinary tap with the housing of the tap 13 is in connection, for the purpose that from the beer line in to let the cask falling back into the upper part of the latter and to avoid stirring the yeast in the lower part of the barrel, as well as a light one To enable cleaning of the beer line. 1 sheet of drawings.
