A fire extinguisher includes a gas generator for pressurizing a suppressant. The generator includes an ignition cord within a flexible tube extending within an interior of an extinguisher bottle. Advantageously, there is additional generant between the tube and the ignition cord. The extinguisher may be manufactured as a retrofit of an existing hand-held supercharged extinguisher.

Pressurization system for fire extinguishers

A discharge valve element seals the outlet of a fire extinguisher vessel holding a fire suppressant. A source of gas pressurizes the suppressant at least when the extinguisher vessel is in a discharging condition. When the pressure acting on the element exceeds the threshold, the force resisting opening the element is overcome and substantially eliminated, whereupon the suppressant discharges through the outlet.

Hybrid fire extinguisher

An apparatus for fire suppression may include a flexible container, a gas generant or other suppressant, initially located within the flexible container, and an initiator. A propagating member may be located within the container to permit the initiator to initiate the generant or expel the other suppressant upon triggering of the initiator to extinguish the fire. A sustainer may be provided to sustain the suppression and may be positioned within a generator housing upstream of the propagating member or at or adjacent the downstream end of the propagating member.
