Abstract
A safety valve includes a cylinder having an open end and a plug for closing the open end with a hermetic seal. The interior of the cylinder communicates with a high-pressure gas passage. The cylinder is deformed as a function of gas pressure in the high-pressure gas passage to widen the open end. This allows gas in the high-pressure gas passage to escape and thus prevents the gas pressure from increasing beyond an acceptable level.
