ABSTRACT:
A fire extinguisher for automotive vehicles, boats, and technical environments which is either automatically controlled, in case of fire, by the action of a thermosensitive cable or, in case of front impact, by the action of a percussion pin switch or manually by a push button located in the interior compartment. It consists of a cylindrical cell box, a valve assembly, a pyrotechnic charge, a bottle of carbon dioxide. When the pyrotechnic charge is electrically energized, it explodes and the percussion pin perforates the diaphragm of the CO2bottle. The gas pressurizes the cell box and causes the extinguishing substance to flow out through a hose at the end of which a nozzle is disposed that sprinkles the extinguishing substance through a circular crown. The fire extinguisher has two small pipes within the cell box which mix CO2with the extinguishing substance.
