The present invention is a fire suppression apparatus for mitigating a battery fire and the effects of a thermal event within a battery pack. The system comprises a fire suppressant apparatus that is incorporated into the storage modules of the lithium ion batteries. Each storage module includes a container filled with a fire suppressant that is pressurized with a compressed gas.

A fluid dispensing apparatus may be used to dispense a paint fluid from a paint container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the paint within the paint container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the paint to flow under the pressure out of the paint container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.

An automatic fire extinguishing system has a tank that contains fire extinguishing agents, and a housing. The housing has a glass bulb retained therein where the glass bulb is exposed by a side connecting hole, and contacted by a moving member that is biased by an elastic body against the glass bulb. When heat is transferred via the side connecting hole to the glass bulb to break the glass bulb, the elastic body biases the moving member to cause the guiding bars to push a striking member so that a striking protrusion on the striking member breaks a membrane that covers the opening of the tank, thereby allowing the pressurized fire extinguishing agents to escape.

A method of actuating an extinguisher system may comprise retaining a broadhead cutter in close proximity to a burst disc surface, receiving an impulse signal, actuating a spring release mechanism in response to receiving the impulse signal, driving a cutter shaft towards the burst disc surface in response to actuation, and piercing the burst disc surface via the broadhead cutter coupled to the cutter shaft.

The proposed technical solution relates to fire prevention equipment and can be used in industrial and civilian properties, including with an increased risk of fire, for locating hot spots, and also for efficiently extinguishing fires in facilities using automatic fire-extinguishing systems. The technical problem addressed by the claimed invention is to produce a fire-extinguishing device which does not have the drawbacks mentioned and has increased reliability, efficiency and manufacturability. The technical result of the claimed invention consists in elimination of the drawbacks of the prior art, in an increase in the reliability and manufacturability of a fire-extinguishing device and thus in an increase in the fire-extinguishing efficiency overall.

An assembly for a fire extinguisher system includes a fire extinguisher fitting that extends into a fire extinguisher container and a fill adapter. The fitting defines a fitting bore through which a connection portion of a pressure monitoring device at least partially extends and a fitting flange that is disposed about the fitting and is disposed parallel to a flange of the pressure monitoring device. The fill adapter includes an adapter housing and an adapter shaft. The adapter housing is arranged to be disposed about the pressure monitoring device. The adapter shaft that at least partially extends through the adapter housing. The adapter shaft is arranged to engage a monitoring housing of the pressure monitoring device.

A portable and reusable liquid spray apparatus, the spray apparatus configured to spray a liquid onto any surface. The apparatus has a spray housing which has a liquid chamber within. The liquid chamber having an opening into which a liquid may be poured and retained within the chamber. A propellant housing configured to engage the spray housing and form a first seal with the spray housing which precludes spillage of the liquid. The propellant housing holds a propellant having a pressure above atmospheric pressure. The propellant housing forms a second seal with the spray housing which precludes leakage of the propellant into the atmosphere. The spray housing also has a passage to supply the propellant into the liquid chamber. The spray housing includes a spray valve and a spray nozzle. The spray valve is configured for releasing the liquid from the apparatus thru the spray nozzle when the valve is actuated. Liquid to be sprayed is poured into the liquid chamber and the propellant housing is engaged with the spray housing. When the spray valve is actuated, the propellant forces the liquid thru the spray nozzle and out of the apparatus.

A method of manufacturing a self-expanding fire-fighting foam solution is disclosed. Here, the method can include purging air from a container, wherein the purging is performed via flowing an inert gas into the container, such that substantially inert environment is created within the container. In addition, the method can further include dispensing or filling a pre-determined amount of foam concentrate into a container, dispensing or filling a pre-determined amount of water into the container, and mixing the foam concentrate and water within the container, wherein the mixed foam and water within the inert container provide the self-expanding fire-fighting foam solution and having a pH ranging from about 6.8 to 7.8 moles per liter.
