A valve assembly includes a valve with a valve body and chamber. A poppet with a stem and piston is slidably engaged inside the valve body. A poppet release mechanism is included for releasing the poppet from a closed position. A mechanism cover is attached to the valve body. A safety mechanism with a pin, spring, and lever is included for preventing the poppet from moving into a fully open position. A first end of the pin extends into the chamber into a pathway of the poppet and a second end of the pin extends into the valve body of the valve. The spring is positioned between and in contact with the pin and the mechanism cover to bias the pin toward the poppet. A first end of the lever is pivotably attached to the pin and a second end of the lever extends out from the valve body.

An exemplary fire suppression system includes a sprinkler nozzle. At least one conduit is connected to the nozzle for delivering a fire suppression fluid to the nozzle. The conduit and the nozzle establish a discharge path. A pneumatically driven pump is connected with the conduit for pumping fluid into the conduit. A gas source provides pressurized gas to the pump for driving the pump. The gas source also provides gas to the discharge path for achieving a desired discharge of the fluid from the nozzle. A controller selectively controls at least one of (i) the gas provided to the pump, which controls the fluid pressure in the conduit, or (ii) the gas provided to the nozzle or the conduit, which controls the gas pressure delivered to the nozzle.

A fire suppression apparatus is described that includes a base and a lid. The base has an opening and walls defining an internal area. The base also includes a sleeve with a portion positioned in the internal area and around a perimeter of the walls, and the sleeve defines a region of the internal area for placing an object. The sleeve also has an opening for placing the object into the region. The base further has a first fire suppressing powder positioned in the internal area between the sleeve and the walls. The lid covers the opening of the base, and has a cavity, a second fire suppressing powder contained inside the cavity, and a divider positioned to cover the cavity of the lid. Methods for suppressing a fire of an object are also described.

Intelligent temperature and pressure gauge assemblies (52) for use with vessels (24) having pressurized hazard suppression materials therein include temperature and pressure sensors (136, 138) coupled with a digital processor (72) with associated memory for storing empirical temperature and pressure data. The data includes normalized linear temperature-pressure curves consistent with static or slowly changing temperature conditions experienced by the vessels (24), as well as nonlinear temperature-pressure curves consistent with rapidly changing temperature conditions. In use, the assemblies (52) repeatedly sense the temperature and pressure conditions of the hazard suppression material and compare these sensed values with the stored values, and generate an output in conformance with the comparison. In this fashion, the assemblies (52) compensate for rapidly changing temperatures without generating false failure signals.

A fire suppression system includes a transport refrigeration unit configured to cool a transport container. Also included is a tubular container having a fire suppressant stored therein, the tubular container disposed within the transport refrigeration unit. Further included is a predetermined fracture location of the tubular container, wherein the predetermined fracture location is configured to rupture upon reaching a critical temperature to expel the fire suppressant.

A method and apparatus for delivering fire retardant to a ground fire from an aircraft. The apparatus includes a dispenser casing that dispenses fire retardant after the casing has been released from an aircraft. The apparatus includes a dispenser fuse that actuates the dispenser casing to dispense the fire retardant in response to one or more predetermined conditions.

A safety assembly provided with an automatic fire extinguisher system includes an engagement member, a blocking member, and an extension member. The engagement member is slidably received within an outlet port of a valve housing. A blocking member having a first blocking member portion and a second blocking member portion is at least partially received within a cavity defined by the valve housing. The extension member extends between the engagement member and the blocking member.

Systems and methods for fire protection of a fixed space using a fire protection unit having a fixed volume of firefighting agent; a manifold coupled to the fixed volume and an actuator axially aligned with the manifold to pressurize the firefighting agent within the manifold for discharge and dispersion to protect the fixed space.

Fire fighting system with a first feed platform arranged for feeding a pipe system having extinguishing nozzles with extinguishing fluid comprising a first sub-system with a first extinguishing fluid reservoir, at least two first propellant gas reservoirs, and a first control circuit, wherein the first propellant gas reservoirs each have a valve for pneumatically coupling the respective first propellant gas reservoir to the extinguishing fluid reservoir and the respective valves can be pneumatically activated in each case via an outlet of the respective other valve, a second sub-system having a second extinguishing fluid reservoir, at least two second propellant gas reservoirs and a second control circuit, the second propellant gas reservoirs each having a valve for pneumatically coupling the respective second propellant gas reservoir to the extinguishing fluid reservoir, and the respective valves being activatable pneumatically in each case via an outlet of the respective other valve, characterized in that the first control circuit is operatively connected to a first one of the valves of the first subsystem and to a second one of the valves of the second subsystem, and in that the second control circuit is operatively connected to a second one of the valves of the first subsystem and to a first one of the valves of the second subsystem.
