Accumulator device e.g. pressure bottle for storing large amount of compressible gas, has bonding agent layer that is provided between inside wall and exterior wall of double-walled pressure tank to stiffener

摘要

The accumulator device comprises a double-walled pressure tank (10) that is provided with an inside wall (14) and an exterior wall (12). A bonding agent layer (20) is provided between the inside wall and exterior wall to a stiffener. The inside wall is made of gastight material and the exterior wall is made of metal sheet or glass. A compression unit (22) is provided with a pressure piston (26) arranged in a cylinder (24). The cylinder is arranged between a hydraulic space (28) and a pressure chamber (30).
