Patent ID: 6907940

Claim:
A fast response flow control valve/nozzle for a high-speed fire protection/suppression system, comprising: a base defining the outer walls of an internal chamber and comprising internal threads at a first end, external threads at said first end, and at least two mounting ports proximate said first end in fluid communication with said internal chamber; a jet core defining the inner walls of an internal chamber and comprising external threads at a first end, said external threads at said first end being releasably attached to said internal threads at said first end of said base; a frangible disc proximate said first end of said jet core and said first end of said base; a retention ring releasably attached at said first end of said base, whereby said frangible disc is positioned between said retention ring and said first end of said jet core; a nozzle port defining a central bore and comprising internal threads at a first end, said internal threads at said first end being releasably attached to said external threads at said first end of said base, thereby enclosing said jet core, said frangible disc, and said retention ring within said internal chamber of said nozzle port and said internal chamber of said base; and an actuator releasably attached to said base at one of said two or more mounting ports; whereby initiation of said actuator creates a localized pressure wave sufficient to rupture said frangible disc to release a fire suppressing material.
