Abstract

A discharge mechanism primarily for a stored-pressure fire extinguisher, in place of the conventional piercer, has a diaphragm 11 closing the outlet passage 18 of the extinguisher, with the central portion of the diaphragm clamped between a pair of plugs 12 and 13. When an operating lever 28 is squeezed a plunger 26 is forced down onto the plug assembly and displaces that assembly upstream into a wider- diameter part of the outlet passage, in so doing the diaphragm 11 being sheared around its periphery to open up the full bore of passage 18 to flow. The plug assembly 12/13 can be allowed to return by releasing the lever 28, to seat against a shoulder 17 and temporarily interrupt the discharge. <IMAGE>
