Abstract
An apparatus 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 The return gas that is to be withdrawn from a container that is being filled is conveyed, accompanied by a pressure differential, into a return gas chamber via a connection that is provided with a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. =
