Abstract
Apparatus for the recovery of an inert gas, preferably for the recovery of CO , for use in counterpressure filling machines, the filling elements of which—prior to introduction of a liquid filling material into a container—evacuate this container and at least prepressurize this container with an inert gas under pressure from the pressurizing gas distribution channel:and which elements, during the subsequent introduction of a filling material, conduct the inert gas containing return gas displaced from a corresponding container into a return gas collection channel, wherein a first evacuation system is provided with which the air can be removed from the bottle, and then there is carried out a prepressurizing of the bottles using an inert gas; and a second independent evacuation system is provided with which can be removed and collected, independently of the first evacuation, the inert gas that is being removed by suction.
