Abstract
A fire extinguishing or suppressing device having a rigid vessel with an interior space and an exit. An unexpandable flexible bladder is positioned in the interior space of the rigid vessel forming a space between the flexible bladder and the rigid vessel. A fire extinguishing composition is contained within the flexible bladder; and a pressurized gas is interposed between the rigid vessel and the flexible bladder.
Claims47
A fire extinguishing or suppressing device comprising:
- a rigid vessel having and interior space and an exit means;
- a substantially unexandable flexible bladder having an inflated stage and a deflated stage positioned in the interior space of the rigid vessel forming a space between the flexible bladder and the rigid vessel, wherein said flexible bladder is substantially flat in said deflated stage;
- a fire extinguishing composition contained within the flexible bladder;
- and
- a pressurized gas interposed between the rigid vessel and the flexible bladder.
A fire extinguishing or suppressing device comprising:
- a rigid vessel having an interior space, an exit means, an axial bore extending between said interior space and said exit means, and a disk transversely positioned across the axial bore;
- a substantially unexpandable flexible bladder positioned in the interior space of the rigid vessel forming a space between the flexible bladder and the rigid vessel;
- a fluid fire extinguishing composition contained within the flexible bladder;
- a pressurized gas interposed between the rigid vessel and the flexible bladder.
A vehicular fire extinguishing or suppressing device comprising:
- a pressurized vessel comprising an outer rigid walled bottle and an internal flexible compressible bladder with a pressurized gas interposed between said rigid walled bottle and said internal flexible compressible bladder, and said vessel having an exit means and said internal flexible compressible bladder having a tube extending axially therein and containing a fire extinguishing composition therein;
- an axial bore connecting the tube in the fire extinguishing composition containing internal flexible compressible bladder and the exit means and a disk, wherein said disk is comprised of nickel alloy and is transversely positioned across the axial bore to restrain release of the fire extinguisher composition from the internal flexible compressible bladder;
- and
- a disk penetrating means comprising a pin which is positioned in the axial bore and is aligned with the disk, whereby the pin is movable with force manually or by an explosive charge means in the axial bore so that the pin penetrates the disk to allow the pressurized gas interposed between the rigid walled bottle and the internal flexible compressible bladder to expel fire extinguishing composition from the internal flexible expandable bladder first through the tube and then through the axial bore and then through the exit means, so that said expelling of the fire extinguishing composition may be accomplished regardless of vehicular position.
A vehicular fire extinguishing or suppressing device comprising:
- a pressurized vessel having an exit means and an internal bladder having a tube extending axially therein and containing a fire extinguishing composition, wherein said bladder is comprised of a flexible compressible noncorrosive material and said pressurized vessel has a rigid wall and a pressurized non-reactive gas is interposed between the rigid wall of the vessel and the flexible bladder;
- an axial bore connecting the tube of the fire extinguishing composition containing bladder and the exit means and a disk comprised of a nickel alloy which is transversely positioned across the axial bore to close said axial bore to restrain release of the fire extinguishing composition;
- and
- a disk penetrating means comprising a narrow elongated member which is positioned in the axial bore and is aligned with the disk, whereby the elongated member is movable with force manually or by an explosive charge in the axial bore so that the elongated member first fractures and then penetrates the disk to allow release of the fire extinguishing composition from the bladder first through the tube and then through the axial bore and then through the exit means, so that said expelling of the fire extinguishing composition may be accomplished regardless of vehicular position.
A vehicular fire extinguishing or suppressing device comprising:
- a pressurized vessel having an exit means and an internal bladder having a tubular fluid conveying means extending axially therein and containing a fire extinguishing composition;
- an axial bore connecting the tubular fluid conveying means in the fire extinguishing composition containing bladder and the exit means and a disk shaped seal comprised of a nickel alloy transversely positioned across the axial bore to close said axial bore to restrain release of the fire extinguishing composition;
- and
- a disk penetrating means comprising a pin positioned in the axial bore which is aligned with the disk and means for applying an axial force manually or by an explosive charge on the pin whereby said means for applying an axial force on the pin causes the pin to move in the axial bore to penetrate the seal to allow release of the fire extinguishing composition from the bladder first through the interior tubular fluid conveying means and then through the axial bore and then through the exit means, so that said expelling of the fire extinguishing composition may be accomplished regardless of vehicular position.
