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.
