1. A filling machine for filling a container with a pasteurized liquid, comprising:

  • a gas line;

    a liquid supply line connectable to a liquid tank;

    at least one filling device including;

    an inlet communicating with the liquid supply line to receive a liquid stored in the liquid tank,a lower outlet for supplying the liquid into a container during filling, anda gas port communicating with the gas line and defining a gas outlet for permitting gas flow from the container towards the gas line during filling;

    a pressure sensor connected to the gas line and to the liquid supply line to determine a feedback value defined by the pressure difference between the liquid supply line and the gas line;

    an electronic control unit configured to adjust the pressure difference between the liquid supply line and the gas line to a set-point in response to the feedback value;

    a gas tank that communicates with the gas line and is separated from the liquid supply line;

    a first valve controlling communication between the gas tank and a pressurized gas source, wherein the first valve is operable by the electronic control unit to open the first valve to increase pressure inside the gas tank; and

    a second valve controlling communication between the gas tank and a discharge opening, wherein the second valve is operable by the electronic control unit to open the second valve to discharge gas from the gas tank when the feedback value is lower than the set-point.
