ABSTRACT:
A method and apparatus advantageously using the shapeless and flowing characteristics of a fluid. The fluid is contained with a suitable film chamber having a given shape; a frame or the like may be used as a supporting means for the chamber. The frame-shaped sack is repeatedly filled and exhausted with a fluid; upon being filled with fluid, it is inflated; upon the fluid therein being exhausted, it becomes deflated. A hollow chamber is supported with a film sack by repeatedly filling and exhausting fluid therefrom so as to have the hollow sack inflated and compressed. By using this method, the hollow sack is used as a pump for pumping a fluid therefrom.
