Publication number: 20240091576Abstract: A fire suppression system includes a feed port and a channel to couple the feed port to an actuation chamber. A solenoid valve controllably blocks a connection between the feed port and the channel. Pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection. A piston is in communication with the actuation chamber. The system also includes an inlet port closed off by a disc. The piston travels through the inlet port and burst the disc based on the pressure in the actuation chamber. An outlet port is coupled to the inlet port.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Inventors: Matthew Allen Newcomer, John Wright Porterfield, JR., David William Frasure

Patent number: 9539452Abstract: 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: GrantFiled: July 11, 2014Date of Patent: January 10, 2017Assignee: KIDDE TECHNOLOGIES, INC.Inventors: David Frasure, John Wright Porterfield, Jr., Harlan Hagge
