A dispensing assembly for automatically adjusting the carbon dioxide level in beer in a draught beer keg (1), said dispensing assembly comprising a beer tap (3) to be placed in the outlet opening (2) of the draught beer keg, a tapping cock (5) connected to said beer tap, a reducing valve (9) communi
A dispensing assembly for automatically adjusting the carbon dioxide level in beer in a draught beer keg (1), said dispensing assembly comprising a beer tap (3) to be placed in the outlet opening (2) of the draught beer keg, a tapping cock (5) connected to said beer tap, a reducing valve (9) communicating with the beer tap (3) and a carbon dioxide compressed air cylinder (7) which in turn communicates with the reducing valve (9). The low pressure side of the reducing valve (9) is directly connected to a gas channel (3a) in the housing of the beer tap (3), said gas channel communicating with the interior of the keg. The reducing valve (9) is a needle/cone valve, where the valve body is controlled by a bellows device (30) arranged in the housing of the valve and including a closed control gas mixture (21) which at least includes carbon dioxide.

1. A dispensing assembly for automatically adjusting the carbon dioxide level in beer in a draught beer keg, said dispensing assembly comprising a beer tap to be placed in the outlet opening of the draught beer keg, a tapping cock connected to said beer tap through a hose, a reducing valve communicating with the beer tap and a carbon dioxide compressed air cylinder which in turn communicates with the reducing valve through a pressure hose, characterised in that the reducing valve is formed as a needle/cone valve, the needle with the cone being controlled by a bellows device arranged in the housing of the valve, the bellows device including a closed control gas mixture and in that the reducing valve is directly connected to a gas channel arranged in the housing of the beer tap, and communicates with the interior of the draught beer keg, said control gas mixture at least including carbon dioxide and being selected such that the carbon dioxide-pressure-temperature-relation of the beer in the keg within a predetermined temperature range, preferably 5 to 30° C., coincides substantially with the carbon dioxide-pressure-temperature-curve for beer with a constant carbon dioxide level of R (% by weight) within said temperature range, R being in the range of 0.43 to 0.62% by weight. 2. The dispensing assembly as claimed in claim 1, characterised in that the carbon dioxide level R (% by weight) of the beer is in the range of 0.48 to 0.57% by weight. 3. The dispensing assembly as claimed in claim 1, characterised in that the control gas mixture in addition to carbon dioxide includes Freon 134A. 4. The dispensing assembly, as claimed in claim 1, characterised in that the carbon dioxide of the control gas mixture represents 10 to 30% by volume of said control gas mixture. 5. The dispensing assembly as claimed in claim 1, and where R is approximately 0.60% by weight, characterised in that the carbon dioxide of the control gas mixture represents approximately 20% by volume, and the content of gaseous hydrocarbon represents approximately 80% by volume. 6. The dispensing assembly as claimed in claim 1, and where R is approximately 0.53% by weight, characterised in that the carbon dioxide of the control gas mixture represents approximately 15% by volume, and Freon 134A represents approximately 85% by volume. 7. The dispensing assembly as claimed in claim 1, characterised in that the reducing valve is shaped such that it can operate with both high and low carbon dioxide pressures because the cone is provided with a slightly convex appearance compared to a geometrical cone. 8. The dispensing assembly as claimed in claim 1, characterised in that the bellows device comprises a cup of sheet material, where a metal sheet bellows is secured inside said cup in a sealing manner, so as to provide a closed chamber for the control gas mixture between the cup and the bellows. 9. The dispensing assembly as claimed in claim 1, characterised in that the metal sheet bellows is formed as a body of revolution with a central projection, which is adapted to press the valve body in the needle/cone valve into an open position through a pressure bar, said valve body also being subjected to an oppositely acting force from a pressure spring arranged in the socket of the reducing valve.
