DEVICE FOR DISPENSING LIQUID PRODUCT FROM CONTAINER UNDER PRESSURE Russian patent published in 1994 - IPC

FIELD: liquid product dispensing equipment. SUBSTANCE: valve 2 is actuated by pressing rod 8, which is retracted into balloon. As a result radial opening 61 is communicated with inner chamber 54 and discharge valve 58 is opened. Passage of rod 8 through annular protrusion 65 results in elastic deformation of extension 66. Bowl-shaped member 3 is formed as cylinder, whose inner diameter exceeds outer diameter of resilient sleeve 4 so that collection chamber 11 is formed between them. Annular gasket 17 is positioned on lower surface 16 of flange 14 and retained on site by casing 18. Dispensing valve and bowl-shaped member are located in casing 18. Casing 18 has stamped annular channel 19, which forms annular protrusion for retaining annular gasket 17, bowl-shaped member, sleeve 4 made from elastomer and dispensing valve. EFFECT: increased efficiency and enhanced reliability in operation. 11 cl, 4 dwg
