Abstract

A filling valve assembly (10) is provided for use in filling containers ( with a carbonated liquid or other type of liquid. The assembly (10) includes a housing (11) having a filling orifice (40) for allowing liquid to flow therethrough. A valve element (13) is located within and movable through the housing (11) and includes a valve seal (36) movable against the housing (11) for selectively opening and closing the filling orifice (40). A capillary screen (38) is connected above the valve seal (36) and is moveable therewith. The orifice (40) is aerodynamically shaped and has an annular enlarged portion (72) smoothly feeding into a narrowed venturi area (76) to continually compress the liquid, and then into an expanded area (70) to the walls of the container (50). A container seal (110) forms part of the expanded area (70) to enhance the laminar flow.

Dependent claims

A filling valve assembly for filling containers with a liquid, said assembly comprising:

housing means (11) having an orifice (40) for allowing liquid to flow therethrough and including an inlet (48) for allowing liquid to flow into said housing means (11) and said orifice (40), an outlet (70) to allow liquid to flow out of said housing means (11) and said orifice (40), and having a valve seat (43) between said inlet (48) and said outlet (70);
valve means moveable within said orifice (40) between said inlet (480) and said outlet (70) and including sealing means (36) moving against said valve seat (43) for preventing liquid from flowing through said orifice (40) to said outlet (70) and moving away from said valve seat (43) for allowing liquid to flow through said orifice (40) to said outlet (70);
and said assembly characterized by including capillary screen means (38) operatively connected between said valve stem (13) and said housing means (11) at a position between said inlet (48) and said sealing means (36) for stopping the flow of the liquid when the containers are filled to a predetermined height.

Dependencies are inferred from the claim text.
