Patent ID: 8813772

Claim:
An article of manufacture forming a safety valve for releasing a pressurized inflammable gas in a hazardous situation, comprising a body defining a gas flow channel extending between an upstream first end intended to be brought into contact with a source of pressurized inflammable gas and a downstream second end intended to be brought into contact with an external atmosphere, the article of manufacture including a plug located on the channel to normally prevent the inflammable gas from flowing between the upstream end and the downstream end, the plug being meltable and/or frangible so as to free the passage for the inflammable gas in the event of a hazardous situation with a pressure and/or the temperature of the pressurized inflammable gas exceeding a predetermined threshold so as to release the pressurized inflammable gas, characterized in that the article of manufacture includes a reservoir of an unstable, exothermically decomposable gas a release of which is adapted to ignite the released pressurized inflammable gas when the unstable gas is in fluid communication with the released pressurized inflammable gas, the reservoir and flow channel are adapted to bring the unstable gas into fluid communication with the released pressurized inflammable gas only when the plug melts/ruptures.
