A filling valve includes a hollow housing including a liquid chamber, a gas chamber, and a sliding valve assembly. The sliding valve assembly includes a hollow valve rod with an opening in the gas chamber at an upper end of the valve rod, the valve rod sliding in the housing between an open position where valve rod opens an aperture in the housing allowing liquid to flow from the liquid chamber through the aperture, and a closed position where the valve rod closes the aperture, and a sliding piston disposed in the housing between an open position where a lower end of the piston is spaced from the upper end of the valve rod allowing gas to pass from the gas chamber to the opening in the valve and a closed position where the lower end of the piston contacts the upper end of the valve rod.

A filling valve () including: a hollow housing (); a moving valve assembly () slidingly mounted in the housing (), the moving valve assembly () and the hollow housing () together defining a liquid chamber () and a gas chamber (); a liquid inlet () for putting the liquid chamber () into communication with a liquid supply pipe (); a gas inlet () for putting the gas chamber () into communication with a gas supply pipe (); wherein the hollow housing () and the moving valve assembly () together define a medium chamber the () located between the liquid chamber () and the gas chamber (), and wherein the filling valve () further comprises: a first diaphragm () linking the valve assembly () to the housing () between the liquid chamber () and the medium chamber (), and a second diaphragm () linking the valve assembly () to the housing () between the gas chamber () and the medium chamber ().

Filling valve () including: a hollow housing () having a valve seat (); a moving valve rod () slidingly mounted in the housing () and having a sealing surface (), the moving valve rod () and the hollow housing () together defining a liquid chamber (); a liquid inlet () for putting the liquid chamber () into communication with a liquid supply pipe (); a device for putting the valve rod () in a first, full-open position, in which the sealing surface () is spaced from the valve seat (), thereby forming a passage () for the liquid; a device for putting the valve rod () in a second, closed position, in which the sealing surface () is in sealing contact with the valve seat (), thereby closing the passage (), and a device for putting the valve rod () in a third, predetermined, semi-open position in which the sealing surface () is spaced from the valve seat () but closer to the same than in the full-open position.

A machine for filling containers includes a series of filling stations, each of which is equipped with an impervious chamber for receiving a container to be filled. The chamber is opened in order to load or unload the container and closed in order to control the atmosphere in the chamber during the filling process. The chamber is delimited by an upper head section, which has a filling spout, by an essentially cylindrical lateral wall and by a base wall. The filling machine has element for modifying the volume of the closed chamber.
