MULTI-SPHERICAL SHELL TYPE HIGH PRESSURE TANK FOR PRESSURE FLUID

PROBLEM TO BE SOLVED: To provide a high pressure tank for a pressure fluid which stores high pressure gas represented by hydrogen gas or fluid such as high pressure liquid represented by chemicals, achieving lighter and more compact construction using a low cost material for suppressing the reduction of storage capacity and producing sufficient pressure resistance to a high pressure level of 300-700 atmospheres, in particular. SOLUTION: The multi-spherical shell type high pressure tank for the pressure fluid comprises a plurality of spherical shell storage chambers continuously provided therein, wherein tank bodies communicating the insides of adjacent spherical shell type storage chambers with each other are sealed with fluid inputs/outputs formed therein. Required strength is secured by increasing the thickness of continuous portions between the spherical shell storage chambers or constraining the continuous portions at their outer peripheries with high tension reinforcing materials arranged in ring shape.
