Remotely actuatable portable fire suppression apparatus

Claim 1

Fire suppression apparatus comprising: a receptacle for a pressurized fire suppressant and having a suppressant outlet; a dual inlet and outlet valve having an internal passage in communication with said outlet and threaded means for the reception of inlet means; inlet means threadably attached to said threaded means and constructed to be selectively opened to allow pressurized fire suppressant to be directed into said receptacle through the valve passage; a relatively thin frangible diaphragm of circular, concavoconvex metallic material and being scored on the convex face thereof, said scored diaphragm being characterized by the property of offering sufficient resistance to rupture under the pressure of the suppressant at temperatures and pressures thereof below the critical values thereof but undergoing rupture upon application of a force thereto exceeding said pressure, said diaphragm being disposed in said cylindrical valve in a spaced, normally blocking relatiOnship to said passage therethrough, the concave face of said diaphragm being in direct facing relationship to the interior of said receptacle; distribution means threadably mounted on said dual valve in aligned, juxtaposed, communicating relationship with said diaphragm blocked passage, and being provided with orifice means for controlling the direction and discharge pattern of the suppressant released through said outlet; and a selectively actuatable detonating component threadably mounted in said distribution means and located in abutting relationship to said diaphragm.
