Abstract:
1. A release valve for a pressurized receptacle having a gas therein, said release valve comprising: a body having a first end and a second end; said body having a communication passage with at least one inlet and an outlet on said first end and a combustion chamber having at least one opening along said second end; a propellant positioned within said combustion chamber; an igniter in communication with said propellant, said igniter adapted to ignite said propellant within said combustion chamber, wherein said igniter has a switch, said switch adapted to be manually engaged to cause said igniter to ignite said propellant; and a valve means movable within said body and extending between said first end and said second end, said valve means movable from a first position to a second position via a thrust of said ignited propellant; said valve means having a first restricting element within said communication passage, said first restricting element adapted to restrict passage of said gas through said outlet in said first position and adapted to permit passage of said gas through said outlet in said second position; said valve means having a second restricting element within said combustion chamber, said second restricting element adapted to restrict passage of heat from said burned propellant through said at least one opening in said first position and adapted to permit passage of heat from said burned propellant through said at least one opening in said second position; said heat from said burned propellant adapted to cause gas within said receptacle to expand and said gases from said burned propellant adapted to add to volume of stored gas expunged through said at least one opening.
