Abstract:
1. A fire extinguishing device comprising: an extinguishing agent tank containing an inlet, an outlet, and an extinguishing agent; pressurized gas generation means for generating a pressurized gas; and communication means connected to a controller that controls a means for regulating a pressure created by the gas in a communicating passageway between the inlet of the extinguishing agent tank and the pressurized gas generation means, such that the pressurized gas generated by the pressurized gas generation means penetrates into the extinguishing agent tank; wherein the controller controls a means for closing the outlet of the extinguishing agent tank to prevent extinguishing within the extinguishing agent tank when not in use, wherein the means for regulating a pressure holds the pressure in the extinguishing agent tank not varying from a nominal value by more than 10% for a given first duration while the extinguishing agent is being ejected outside said extinguishing agent tank, and wherein the inlet of the extinguishing tank is located in an upper portion of the tank for input of the pressurized gas.
