Patent GB-989998-A (GB)
Title: Improved filling valve for bottling liquids
Inventor: BROWN LESLIE KENNETH
IPC: B67C3/26
Filed: 1963-08-19
Abstract: 989,998. Bottling. LESBRO ENGINEERING PRODUCTS (PROPRIETARY) Ltd. Aug. 19, 1963, No. 32708/63. Heading B8T. In a valve for introducing gasified liquids into containers in a counter-pressure filling machine, a liquid-flow responsive valve 8, intended to prevent liquid entering a gas tube 6, comprises a sleeve 9 closed by a plug 11, a nozzle 14 integral therewith having a through port 12 and side ports 18 and a thimble 16 loosely fitted on to the nozzle and carrying a valve seal 17 adapted to bear against a valve seat 10. In operation the container 5 is pregassed by discharge of gas from tube 6 through ports 18 and 12 via an annules 19 between sleeve 9 and nozzel 14. Thereafter liquid flows into the container via annulus 7, or an equivalent passageway, and a reverse flow of gas to that mentioned above occurs until the liquid level reaches sleeve 9 when liquid starts to flow upwardly as a jet through port 12 to project the thimble 16 so that seal 17 engages seat 10. Upward flow of liquid or gas is thus prevented and further inflow of liquid to the container is also prevented by increase of gas pressure therein. The relative sizes of ports 18 and port 12 are such that a substantial inflow of gas is possible, but only a restricted outflow of liquid through ports 18 is permitted, the liquid flow having a strongly preferential path through port 12. After filling, any liquid contained in sleeve 9 gravitates into the container when gas pressure therein is released. Snifting is aided by auxiliary gas ports 20 in plug 11.
