PROBLEM TO BE SOLVED: To increase a filling quantity of a pressurized fluid, while simplifying a mechanism for supplying the pressurized fluid being a driving source of a pressurized medium driving device.SOLUTION: This pressurized fluid supply device includes a pressurized fluid storage vessel 1 having a valve mechanism 7 having a needle valve 13 for opening-closing a gas injection hole 15 for injecting liquefied carbon dioxide, a storage vessel support 2 provided with a plurality of vessel installing parts 30 for installing this vessel, provided with a plurality of piston cylinders 38 for arranging a piston 39 for opening the gas injection hole by pressingly operating the needle valve of the pressurized fluid storage vessel and further forming a pressurized fluid flow passage 34 for introducing the carbon dioxide jetted from the respective pressurized fluid storage vessels to a pressurized outflow port 33, and a valve control mechanism 7 for simultaneously pressingly operating the piston arranged in the respective piston cylinders. A plurality of pistons simultaneously pressingly operate by the valve control mechanism, and the injection hole is opened by simultaneously movably operating a plurality of needle valves, and the carbon dioxide is simultaneously made to flow out to an external part from a plurality of pressurized fluid storage vessels. |
