Abstract
An arrangement for filling bottles under counterpressure and comprising at least one filling element relative to which a respective container is sealed during a filling process. The arrangement also has at least one gas channel that communicates with the interior of the container that is to be filled. Gas can be supplied in a controlled manner to the interior of the container from a chamber via the gas channel, and return gas displaced from the container during a filling process can be withdrawn to the chamber via the gas channel and at least one gas path. This gas path has an individually controllable control valve, and in series therewith a device that automatically controls the effective flow cross-section of the gas path in such a way that this flow cross-section is smaller in one direction of flow than in another, opposite direction of flow.
