Abstract
A valve mechanism for opening the seal on a high pressure gas cylinder, e.g., a cylinder having an internal pressure on the order of 6,000 psi, is provided. The valve includes a piston assembly which carries a cutter for puncturing the cylinder's seal. The initial puncture is performed manually. Thereafter, the escaping gas from the cylinder is used to force the piston towards the seal to complete the puncturing process.
