A method for filling containers, under counterpressure, with carbonated liquids. The return gas, that is to be withdrawn from a container that is being filled, is conveyed, accompanied by a pressure differerntial, into a return gas chamber via a connection that is provided with a flow control mechanism. In this return gas chamber a pressure is regulated that is adjustable within a range that is between the filling pressure and the critical pressure of the flow control mechanism. In this way, the flow velocity with which the dispensed liquid flows into a container that is being filled can be smoothly adapted in an infinitely variable manner to the filling characteristics of a respectively dispensed liquid, and/or to the respective output requirements of the filling apparatus.

A method of filling a carbonated liquid, particularly beverages, into a container under counterpressure, said method comprising the steps of: preliminarily pressurizing said container with pressurizing gas; then introducing, via a filling element, said liquid, which is under a filling pressure, into said container when the latter is in a sealing position with respect to said filling element; during said introducing of liquid into said container, at least for a given period of time, withdrawing from said container, the gas or gas mixture, formed by return gas, that is displaced by said introduced liquid involving a pressure differential between filling pressure of the liquid and the gas or gas mixture in the container under counterpressure, and thereupon conveying said gas or gas mixture into a chamber via a connecting means that is provided with a flow control mechanism, said flow control mechanism including a space having a pressure relationship of gas or gas mixture therein beyond which upon pressure increase at an output from the space of said flow control mechanism the volume flow of return gas displaced from the container by the liquid and passing through the flow control mechanism has an interdependent interrelationship of the pressure with respect to the gas or gas mixture and the liquid; regulating in said chamber a pressure that is adjustable within a range that is between said filling pressure and the pressure of said flow control mechanism; interrupting said connecting means upon termination of introduction of liquid into said container; and thereupon reducing the pressure in said container to atmospheric pressure.
