HYBRID FIRE EXTINGUISHER

HYBRID FIRE EXTINGUISHER

A discharge valve element (134, 216) seals the outlet of a fire extinguisher vessel holding a fire suppressant (24, 203). A source (34, 240, 302) of gas pressurizes the suppressant at least when the extinguisher vessel is in a discharging condition. When the pressure acting on the element exceeds th...

description A discharge valve element (134, 216) seals the outlet of a fire extinguisher vessel holding a fire suppressant (24, 203). A source (34, 240, 302) 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. Further, the invention discloses a ignition device for a fire extinguisher propellant.
