Abstract: A vessel mouth gasket unit is fitted around the outer periphery of a valve body which is internally formed with a filled liquid passage. A first gasket having a smaller diameter and a second gasket having a larger diameter is mounted on the lower surface of the unit. The filling valve is made up of a liquid valve opening and closing air cylinder which opens and closes a liquid valve 8 disposed in the filled liquid passage, and a vessel mouth gasket auxiliary air cylinder which urges the unit downward. The valve body has an outer diameter which is greater than the aperture diameter of a bottle-like first type vessel and less than the aperture diameter of a second type vessel having a larger aperture. The operating pressure of the auxiliary air cylinder is controllable and the filling operation takes place by urging the gasket against the first vessel with a low load and by urging the gasket against the second type vessel with a high load.

Abstract: The present invention provides a filling valve which affords an excellent sterilization capability and a high maintenance capability. The valve includes a tubular nozzle 4, an operating rod 6 which is fitted in the nozzle 4 so as to be elevatable, and an opening/closing valve 22 formed by a valve seat 10a on the internal surface of the nozzle 4 at its bottom end and a valve element 6a formed at the bottom end of the operating rod 6. A portion 10c of a reducing diameter which gradually reduces the cross-sectional area of the filled liquid passage 10 in a downward direction and a portion 10e of an increasing diameter which gradually increases the cross-sectional area of the filled liquid passage 10 in the downward direction are formed on the internal surface of the nozzle 4 at an upper portion thereof. A plurality of straightening vanes 36 are formed on the internal surface of the nozzle 4 at a location below the portion 10e of an increasing diameter.

Abstract: A vessel mouth gasket unit 32 is fitted around the outer periphery of a valve body 2 which is internally formed with a filled liquid passage 4. A first gasket 38 having a smaller diameter and a second gasket 40 having a larger diameter is mounted on the lower surface of the unit 32. The filling valve comprises a liquid valve opening and closing air cylinder 16 which opens and closes a liquid valve 8 disposed in the filled liquid passage 4, and a vessel mouth gasket auxiliary air cylinder 42 which urges the unit 32 downward. The valve body 2 has an outer diameter D0 which is greater than the aperture diameter D1 of the bottle-like first type vessel B and less than the aperture diameter D2 of the second type vessel C having a larger aperture such as a canister. An operating pressure of the auxiliary air cylinder 42 is controllable and the filling operation takes place by urging the gasket 38 against the first vessel B with a low load and by urging the gasket 40 against the second type vessel C with a high load.
