Abstract: An aircraft fuel tank vent (100, 200, 300) having a first interface (102, 202, 302) for fluid communication with an aircraft fuel tank interior, and a second interface (104, 204, 304) for fluid communication with an aircraft fuel tank exterior, the vent comprising: a first flow path (118, 218, 326) between the first interface and the second interface, the fuel tank vent having a baffle (126, 226, 317) positioned in the first flow path, and, a second flow path (124, 224, 326) between the first interface and the second interface, the fuel tank vent having a overpressure device (120, 220, 322) positioned in the second flow path, wherein the first and second flow paths are common along at least a part of their length such that they are coincident at the second interface.

Abstract: A fire suppression device characterized by a plunger that is extendible from a housing for delivery of a fire suppressant foam. The plunger may be equipped at its outer end with a puncture tip that can penetrate through the wall of a container or cargo cover for delivery of the fire suppressant foam directly to the cargo, preferably after full or almost full extension of the plunger. The plunger may be driven outwardly under high force by a pressurized gas that may also be used as a propellant for mixing with a liquid foaming agent, preferably within a foaming chamber carried by the piston. Provision may also be made for connection to a source of pressurized fluid to effect retraction of the plunger.
