ABSTRACT:
A fire extinguisher which maintains a constantly high pressure inside a shell of the fire extinguisher through out a shelf-life of the fire extinguisher comprising an ejection chamber having internal threads at its lower edge and a shell having external threads at its upper edge to mate tightly with internal threads of ejection chamber where shell contains fire extinguishing agent in an absolutely closed system, and where there is a pressing element presses on top of a plate fillet welded to an inner lower wall of the ejection chamber. Upon destroying pressing element, pressure inside shell causes a hole being formed in said plate allowing ejection of fire extinguishing agent to put out fire. An automatic fire extinguishing system is described using newly invented fire extinguisher to extinguish fire immediately when a detector is actuated by any substances built-up during a fire to cause destroying of a plastic stopper cartridge at an end of a pipe resulting in opening up pipe end and also resulting in a hole being formed in said plate fillet welded to an inner lower wall of the ejection chamber of fire extinguisher to allow ejecting of fire extinguishing agent to put out fire starting in a room. A number of fire extinguishers can be connected in series with a pressure sensor installed in a pipe between each one, and from which fire extinguishing agent can be successively ejected out until fire is completely put out. An automatic fire extinguishing system for an oil storage tank is described.
