Abstract
To downsize a high-pressure tank apparatus comprising: a high-pressure tank in which high-pressure gas is charged; and a valve mechanism including a regulator valve for reducing the gas pressure in the tank, to prevent damage to the valve mechanism, and to facilitate the handling of the valve mechanism and the like, the valve mechanism is provided at a gas outlet of the high-pressure tank to locate inside of the tank. The valve mechanism includes a capsule fixedly attached to the gas outlet in a gas-tight manner to face the inside of the high-pressure tank. Within the capsule, a shut-off valve for providing and interrupting communication between the inside and outside of the tank by its opening and closing, respectively, and a regulator valve for reducing the pressure of the high-pressure gas in the tank are disposed.
