  • Patent number: 5111857
    Abstract: In a rotating container filling machine, the assembly (10) supplies liquid to a plurality of valves. The assembly (10) comprises a fixed tube (18), housed in a housing (16), supplying liquid to a distribution assembly (20) which mounts on and rotates with respect to the housing. The distribution assembly (20), including a rotating tube (22) and a cover (26), in turn supplies liquid to the valves (12) through conduits 24 for filling the containers (14). The rotating tube (22) telescopinigly engages in close tolerance within the fixed tube (18) and is rotatably supported therein by tube bearings (100, 102). The cover (26) of the distribution assembly (20) telescopingly engages over the housing (16) and is rotatably supported thereon with housing bearings (110, 112). The housing bearings (110, 112) includes upper (110) and lower (112) bearings disposed between the housing (16) and the cover (26).

  • Patent number: 5085255
    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.

  • Patent number: 4979546
    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.
