Abstract: A self-activating fire extinguisher includes a pressure vessel having an outlet and containing a fire suppressant therein. A fusible material caps the outlet such that melting the fusible material allows escape of the fire suppressant from the pressure vessel. A deflector is associated with the pressure vessel for deflecting the fire suppressant escaping the pressure vessel onto a corresponding hazard.

Abstract: An automatic fire extinguisher that is self-activated in the presence of specified temperature. The fire extinguisher includes a sealed pressure vessel having a fitting and a tube permitting access to the contents of the pressure vessel. A valve in the end of the tube includes a fusible alloy temperature sensor designed to melt or soften in the presence of heat and/or flame. Once the temperature sensor softens or melts, the contents of the pressure vessel are released through the valve thereby extinguishing the fire. A capillary tube is provided to charge the pressure vessel with fire suppressant agent and a pressurized gas.
