Publication number: 20160008647Abstract: According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent at an internal fire extinguisher pressure within the fire extinguisher reservoir. A cutter is detained within the fire extinguisher proximate the fire extinguisher outlet burst disc. An interior container within the fire extinguisher reservoir has a container pressure and is sealed with a container burst disc. An activation device having a piercing member is operable to pierce the container burst disc and diffuse the container pressure to create a pressure differential relative to the internal fire extinguisher pressure at the cutter, thereby driving the cutter through the fire extinguisher outlet burst disc to release the pressurized fire extinguishing agent through the discharge head.Type: ApplicationFiled: July 11, 2014Publication date: January 14, 2016Inventors: David Frasure, John Wright Porterfield, JR., Harlan Hagge

Publication number: 20160008646Abstract: According to one aspect, a fire extinguisher actuator assembly for a fire extinguisher is provided. The fire extinguisher includes a fire extinguisher reservoir and a burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent within the fire extinguisher reservoir. The fire extinguisher actuator assembly includes a cutter shuttle assembly having a cutter coupled to a shuttle body. The cutter shuttle assembly is detained within the fire extinguisher proximate the burst disc and biased to form a pressure equalization region between the shuttle body and the burst disc. The fire extinguisher actuator assembly also includes an activation device having a piercing member operable to pierce the burst disc and release pressure from the pressure equalization region, thereby driving the cutter through the burst disc to release the pressurized fire extinguishing agent through the discharge head.Type: ApplicationFiled: July 11, 2014Publication date: January 14, 2016Inventors: David Frasure, John Wright Porterfield, JR.
