PURPOSE:To aim at getting rid of unevenness in injection quentities so much as almost nothing, by injecting liquefied gas into a can gently after turning the gas into a fine filiform something via a filtrable receptacle, while making the injection constant. CONSTITUTION:An inner valve 4 is unified with a shaft 8 provided with a movable spring supporting frame 12 in structure. The position of this shaft 8 depends upon where a vertically driving bar 13 is positioned. Therefore, if it is once determined, the relative positions of the inner valve 4 and a seat valve 5 are as well determined, causing a certain amount of liquefied gas to enter a filtrable receptacle. The liquefied gas entering the filtrable receptacle 6 is once rectified and then flows down from a liquefied gas flow-down port 19 in threadlike form. The dropped liquefied gas is injected into a soft can and unevenness in injection quentities therefore vanishes into almost nothing. |
