Abstract
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.
