Abstract: A valve actuation mechanism has a plurality of links. Each link has a proximal end and distal end, and the links are disposed adjacent a valve member. The actuation mechanism also has at least one roller connected to the distal ends of at least two links. The roller contacts a surface of the valve member. In addition, at least one pivot for each link is present in the valve, wherein each pivot is positioned on the proximal end of each of the plurality of links.

Abstract: A threaded interface includes a male threaded body and a female threaded body. The male threaded body includes a threaded section with external threads and a seal section with a plurality of o-rings seated circumferentially around the threaded body. The female threaded body includes a threaded section with internal threads and a seal section. The seal section of the female threaded body sealingly engages the o-rings of the seal section of the mail threaded body. A pressure vessel and a pressure vessel assembly for an automatic fire extinguishing system incorporating the threaded interface are also disclosed.

Abstract: A fire extinguishing system for use in a crew compartment of a ground-based vehicle includes at least two cylinders. The cylinders dispense a fire extinguishing agent through a release mechanism. A control for the overall system is operable to actuate the two cylinders. A nozzle is positioned downstream of the release mechanism to distinguish the extinguishing agent into the crew compartment. The majority of the dispensing from at least a first of the two cylinders occurs in less than five seconds.
