A fire extinguisher of the type comprising a burstable container adapted to provide a high mass flow rate of discharged extinguishant is provided with venting means so adapted to direct the flow of extinguishant from the container that the reaction forces upon the container during discharge of extinguishant compensate one another to minimize the resultant force upon the container. The venting means comprise at least one diaphragm burstable by a detonator device housed in a frangible well which extends into the container.

A fire extinguisher comprising a container having a wall which defines a chamber for a source of extinguishant, a diaphragm which is burstable by a detonator device in said container and which permits, upon bursting thereof, a high mass flow rate of extinguishant from the container, and venting means through which extinguishant flowing from the burstable part of the container may be discharged, said venting means including a number of axial pillars defining a plurality of discharge orifices through which extinguishant flowing from the burstable part of the container may be discharged, the number, size and position of said discharge orifices being balanced in such a manner that the reaction forces upon the container due to the flow of extinguishant from the discharge orifices substantially balance one another, and said diaphragm having a center and being formed with a number of lines of weakness which extend outwardly from said center and which promote bursting of said diaphragm into segments, said lines corresponding in number to and being substantially staggered in position in relation to said pillars which will thus be engaged by the segments on bursting of the diaphragm and blocking of said discharge orifices by said segments will be minimized.
