  • Patent number: 8381777
    Abstract: 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.

  • Patent number: 8109299
    Abstract: A filling valve (12) including: a hollow housing (21); a moving valve assembly (24) slidingly mounted in the housing (21), the moving valve assembly (24) and the hollow housing (21) together defining a liquid chamber (30) and a gas chamber (32); a liquid inlet (46) for putting the liquid chamber (30) into communication with a liquid supply pipe (14); a gas inlet (47) for putting the gas chamber (32) into communication with a gas supply pipe (17); wherein the hollow housing (21) and the moving valve assembly (24) together define a medium chamber the (33) located between the liquid chamber (30) and the gas chamber (32), and wherein the filling valve (12) further comprises: a first diaphragm (35) linking the valve assembly (24) to the housing (21) between the liquid chamber (30) and the medium chamber (33), and a second diaphragm (36) linking the valve assembly (24) to the housing (21) between the gas chamber (32) and the medium chamber (33).
