Abstract: A filling machine includes a filling tube passing through a spout endpiece to delimit with the spout endpiece, part of an air return circuit. The filling tube is vertically movable and delimits an exit passage for the liquid. A control circuit is provided for moving the filling tube to a low position and driving an obturation device to open the exit passage, putting the air return circuit, when the exit passage of the filling tube is immersed in the liquid, to atmospheric pressure, moving the filling tube towards its leveling position, putting the air return circuit in communication with a pressurized chamber, and bringing the filling tube to a leveling position.

Abstract: A method of filling containers with the help of a filler liquid stored in a pressure regulated vessel and delivered using at least one filler head comprises a filler tube and provided with a main shutter, the filler tube including internally a discharge cannula. After engaging the filler tube inside the container, the main shutter of the tube is opened and a vent is created for the container and for the cannula, communication between the cannula and the vessel being closed. Before the end of filling, the vent is closed and the cannula is put into communication with the vessel. At the end of filling, when the liquid reaches a determined level of the tube, the shutter of the tube is closed, and communication between the discharge cannula and the vessel is closed.
