Abstract
A filling valve assembly (10) is provided for use in filling containers (50) with a carbonated liquid or other type of liquid. The assembly (10) includes a housing (11) having a filling passage (40) for allowing liquid to flow therethrough. A valve stem (13) includes a passageway (24) therethrough and is slideable within the passage (40) wherein a first end allows gas into the passageway (29) and a second end allows gas to escape and supports a valve seal (36) thereabout. The valve seal (36) is movable against the housing (11) for selectively opening and closing the filling passage (40). A capillary screen (38) is connected above the valve seal (36) and is moveable therewith. A resilient charging cap (24) operates against the first end of the valve stem (13) for opening to allow gas therein and closing to disallow gas therein. The valve stem (13) includes a key above the liquid flow and cooperating with a groove in a guide (15 ) of the housing (11) to prevent rotation thereof.
