Abstract
Claims
1. A pressure vessel for storing fluids, The pressure vessel comprises a liner, The liner comprises a plurality of main body portions that are extended cylindrical bodies, and a plurality of connecting portions that connect two adjacent main body portions in series and bend the plurality of main body portions so as to fold them. A pressure vessel in which the plurality of connecting parts are separate from adjacent main body parts and include at least one low-elasticity connecting part having a lower modulus of elasticity than these main body parts.
2. The pressure vessel according to claim 1, wherein the low-elasticity connecting portion comprises a bent portion and tapered portions on both sides of the bent portion that directly connect to the adjacent main body portion, and the low-elasticity connecting portion is composed of a layered structure containing the same or common resin material as the adjacent main body portion throughout.
3. The pressure vessel according to claim 2, wherein the low-elasticity connecting portion is composed of the layer structure containing an elastomer resin material.
4. The pressure vessel according to claim 3, wherein the low-elasticity connecting portion has a thickness of no more than twice the thickness of the adjacent main body portion.
5. The pressure vessel according to any one of claims 1 to 4, wherein the low-elasticity connecting portion is connected to the main body portion by laser welding.
