Inflator based fire suppression system

A fire extinguisher for suppressing a fire, said fire extinguisher comprising:

• a pressure bottle defining an opening at one end thereof;
• a tubular diffuser-actuation housing mounted in said opening, the tubular diffuser-actuation housing having a first tubular portion projecting axially into said pressure bottle and an opposite, second tubular portion projecting axially outwardly from said pressure bottle, said housing defining a tubular sidewall terminating in an endcap in said pressure bottle, and a mouth outwardly of said pressure bottle, said mouth having an initiator mounted therein;
• the second tubular portion of the housing having a plurality of radial diffuser ports circumferentially spaced around said tubular sidewall;
• the first tubular portion of the housing having a plurality of exhaust ports therethrough for defining access from interior of the pressure bottle to interior of the tubular housing;
• a frangible burst disk mounted in said tubular housing intermediate the exhaust ports and the diffuser ports, said burst disk interrupting flow paths between said exhaust ports and said diffuser ports until said burst disk is ruptured;
• burst disk rupture means axially intermediate the initiator and the burst disk, said rupture means being for rupturing the burst disk upon actuation of the initiator and thereby open said flow paths;
• fire suppression material housed in said pressure bottle;
• and
• a source of pressurized gas within said fire extinguisher comprising a gas-producing combustible material in the tubular housing, wherein said gas-producing material is combustible to produce the pressurized gas upon actuation of the initiator for causing the fire suppression material to flow through the exhaust ports, along the flow paths, and out the diffuser ports upon rupture of the burst disk.
