DEVICE FOR OVERHEAT PROTECTION FOR A TYPE 4 COMPRESSED GAS CONTAINER

摘要

A pressure container (70) for storing hydrogen gas (26) under pressure for a fuel cell engine. The container (70) includes an outer support layer (12) and a thermoplastic liner (14). An adapter (18) is provided in the outer layer (12) and the liner (14) to allow fill gas (20) to fill the container (70) under pressure. A fill vessel (72) is provided within the liner (14) and is sealed and thermally coupled to the adapter (18). The fill gas (20) is confined within a gap (78) between an outer surface of the fill vessel (72) and the liner (14) so that the temperature of the liner (14) is not significantly increased during the fill process. An opening (82) is provided in the fill vessel (72) so that the fill gas (20) forces the contained gas (26) within the container (70) into the fill vessel (72) through the opening (82).
