This punctures the outer surface of cartridge 420, fluidly coupling internal volume 422 with actuator 430. In some embodiments, activation mechanism 436 punctures cartridge 420 only when actuator 430 is activated. In some such embodiments, activation mechanism 436 omits any valves that control the flow of expellant gas to hose 434. In other embodiments, activation mechanism 436 automatically punctures cartridge 420 as neck 424 engages actuator 430.
  • the expellant gas from cartridge 420 flows freely through neck 424, actuator 430, and hose 434 and into neck 416.
  • the expellant gas forces fire suppressant agent from fire suppressant tank 412 out through neck 416 and into a conduit or hose, shown as pipe 440.

  • Neck 416 defines an outlet (e.g., using a syphon tube, etc.) near the bottom of fire suppressant tank 412.
  • the pressure of the expellant gas at the top of internal volume 414 forces the fire suppressant agent to exit through the outlet and into pipe 440.
  • the expellant gas enters a bladder within fire suppressant tank 412, and the bladder presses against the fire suppressant agent to force the fire suppressant agent out through neck 416.
  • pipe 440 and hose 434 are coupled to fire suppressant tank 412 at different locations.
  • hose 434 may be coupled to the top of fire suppressant tank 412, and pipe 440 may be coupled to the bottom of fire suppressant tank 412.
  • fire suppressant tank 412 includes a burst disk that prevents the fire suppressant agent from flowing out through neck 416 until the pressure within internal volume 414 exceeds a threshold pressure. Once the pressure exceeds the threshold pressure, the burst disk ruptures, permitting the flow of fire suppressant agent.
  • fire suppressant tank 412 may include a valve, a puncture device, or another type of opening device or activator assembly that is configured to fluidly couple internal volume 414 to pipe 440 in response to the pressure within internal volume 414 exceeding the threshold pressure.
  • a puncture device or another type of opening device or activator assembly that is configured to fluidly couple internal volume 414 to pipe 440 in response to the pressure within internal volume 414 exceeding the threshold pressure.
  • Such an opening device may be configured to activate mechanically (e.g., the force of the pressure causes the opening device to activate, etc.) or the opening device may include a separate pressure sensor in communication with internal volume 414 that causes the opening device to activate.
  • Pipe 440 is fluidly coupled to one or more outlets or sprayers (e.g., nozzles, sprinkler heads, discharge devices, dispersion devices, etc.), shown as nozzles 442.
  • the fire suppressant agent flows through pipe 440 and to nozzles 442.
  • Nozzles 442 each define one or more apertures, through which the fire suppressant agent exits, forming a spray of fire suppressant agent that covers a desired area. The sprays from nozzles 442 then suppress or extinguish fire within that area.
  • the apertures of nozzles 442 may be shaped to control the spray pattern of the fire suppressant agent leaving nozzles 442.
  • Nozzles 442 may be aimed such that the sprays cover specific points of interest (e.g., a specific piece of restaurant equipment, a specific component within an engine compartment of a vehicle, etc.). Nozzles 442 may be configured such that all of nozzles 442 activate simultaneously, or nozzles 442 may be configured such that only nozzles 442 near the fire are activated.
  • specific points of interest e.g., a specific piece of restaurant equipment, a specific component within an engine compartment of a vehicle, etc.
  • Fire suppression system 410 further includes an automatic activation system 450 that controls the activation of actuator 430.
  • Automatic activation system 450 is configured to monitor one or more conditions and determine if those conditions are indicative of a nearby fire. Upon detecting a nearby fire, automatic activation system 450 activates actuator 430, causing the fire suppressant agent to leave nozzles 442 and extinguish the fire.
  • Fire suppression system 410 further includes a manual activation system 460 that controls the activation of actuator 430.
  • Manual activation system 460 is configured to activate actuator 430 in response to an input from an operator.

  • Coupled means the joining of two members directly or indirectly to one another. Such joining may involve one member supporting another member directly or indirectly. Such joining may be stationary (e.g., permanent or fixed) or moveable (e.g., removable or releasable). Such joining may be achieved with the two members coupled directly to each other, with the two members coupled to each other using a separate intervening member and any additional intermediate members coupled with one another, or with the two members coupled to each other using an intervening member that is integrally formed as a single unitary body with one of the two members.
  • Coupled or variations thereof are modified by an additional term (e.g., directly coupled)
  • the generic definition of “coupled” provided above is modified by the plain language meaning of the additional term (e.g., “directly coupled” means the joining of two members without any separate intervening member), resulting in a narrower definition than the generic definition of “coupled” provided above.
  • Such coupling may be frictional, mechanical, electrical, or fluidic.
