PRESSURIZING FILLING VALVE

PROBLEM TO BE SOLVED: To provide a pressurizing filling valve in which sanitary properties are improved by eliminating a sliding part of a packing unit for a container opening and a gas substitution efficiency is high. SOLUTION: A filling liquid passage 4 is formed in a valve housing 2 and it is communicated and shut down by opening and closing of a liquid valve 12. A packing 44 for a container opening is fitted on the outer periphery of the valve housing 2 so as to be able to elevate and lower, and is fitted to the valve housing 2 through a bellows 46. A gas feeding passage 68 and a gas exhausting passage 70 are formed on the outside of the filling liquid passage 4 in the valve housing 2. The lower part of the valve housing 2 is cut out, and the opening part 72a of the gas exhausting passage 70 is opened at this cut-out part 2c, and is positioned above the opening part 68a of the gas feeding passage 68 and at approximately the same height as a fitting position (the undersurface 46aa of an upper thick-walled part 46) of the bellows 46.
