The invention relates to a method for filling gaseous liquids, such as beer, Sparkling wine, lemonade and the like ', in which the liquid under pressure in a distribution container in a filling vessel, e.g. B. a bottle is passed and this filling vessel with a pressurized gas source is connected to pressurize it, and communicates with a discharge cock, which the outflow of the gas contained in the filling container is permitted, with the filling vessel during a short filling start-up time, a pressure is generated which is preferably somewhat lower than that in the distribution container prevailing, and on a device for carrying out the method.

A method of the type explained at the beginning for filling bottles is known, in which in The pressure in the bottle during filling is slightly higher than in the distribution container. Merely to At the beginning of the filling process, the pressure in the vessel to be filled is used to suck in the liquid Made a little lower than in the distribution tank. In this known method, the outflow of the gaseous liquid during the filling of the bottles unfavorably only with very little Speed. The speed is determined by the difference in level between the lower end of the outlet tap and the liquid level in the distribution container, the hydraulic load given by this level difference also compared to the above Liquid level in the distribution container has to overcome a slightly higher pressure in the filling vessel. Through the The resulting very low outflow velocity is a relatively long time to fill the filling vessels necessary. The known method is therefore uneconomical.

Processes are also known in which the outflow the gaseous liquids takes place under constant pressure, d. i.e. the pressure in the distribution tank is practically the same as that prevailing in the filling vessels, so that the flow velocity only from the hydraulic load contained in the distribution tank and in the filling element Column of gaseous liquid, therefore depends on the difference in piezometric filling heights.

The amount of outflow is determined by the cross-section of the machined into the discharge valve Outflow line and by the flow rate; it can be increased, either by one Enlargement of the line cross-section or by increasing the flow velocity.

However, if the filling vessels are bottles, this is the case

Increasing the cross-section of the line set a limit by the diameter of the bottle neck, which is standardized. If the filling line also ends in a tube dipping into the bottle, so the line cross-section is also limited by what has to be maintained in the bottle Level, because the volume of the unfulfilled space remaining in the bottle after filling equal to the product of the outer pipe cross-section and the immersion length of the pipe.

In addition, in order to increase the flow rate, filling machines were also constructed, in which the distribution container is arranged much higher than in the usual devices.

Since the space requirement must still be limited, the search was made even with excessive reservoirs Increase flow rate by being at a lower level than the main reservoir provided a start-up reservoir. In this case, the start-up container delivers at the beginning of the transfer, and the distribution container only comes into operation when the liquid level in the bottle reaches the mouthpiece reached at the end of the filling tube.

Whichever solution was used, the flow rate remained relatively low, which means that the capacity of the transfer devices is considerable is limited.
