Abstract

A piston-type valve switch utilizes its piston and a mating sealing ring to perform short-distance reciprocal linear movement between a liquid inlet or a liquid outlet for automatically switching the valve to open or close. The driving energy can be directly from a cylinder or indirectly from a pump hydraulic pressure variation for opening or closing; even without external driving energy, the open/close action can also be easily operated by manually placing, piling and removing of a packaging container. The piston having groove can be equipped with sealing rings; for piston having no groove, additional sealing ring is disposed at a base seat of liquid in/out valve. The piston having groove can be further provided with holes for liquid communicating, and can be combined with a filling pipe to form an integral member. A liquid is transported by gravity and the air pipes marking with various levels inside the quantitative tube are chosen to use to form a powerless or semi-automatic quantitative filling device or a fully automatic quantitative filling device using cylinder as power source.
