Abstract:
A vehicular fire extinguishing or suppressing device comprising:(a) a pressurized vessel comprising an outer rigid walled bottle and an inner flexible bladder with a pressurized gas interposed between said rigid wall and pressurized bladder, and said vessel having an exit means and an internal bladder containing a fire extinguishing composition in said flexible bladder;(b) an axial bore connecting the fire extinguishing composition containing bladder and the exit means and a disc having a scored dome shaped section, wherein said disc is transversely positioned across the axial bore to close said axial bore to restrain release of the fire extinguisher composition; and(c) a disc penetrating means comprising an explosive charge and a pin mounted on a plunger and said pin has a flattened tip and is positioned in the axial bore and is aligned with the scored dome section of the disc, whereby activation of the explosive charge causes the plunger and the pin to move in the axial bore so that the flattened tip of the pin first fractures the scored dome shape section of the disc and then penetrates the disc to allow release of the fire extinguisher composition from the bladder first through the axial bore and then through the exit means.
