  • Patent number: 10226656
    Abstract: 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.

  • Patent number: 9821183
    Abstract: According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent within the fire extinguisher reservoir. The fire extinguisher actuator assembly includes a cutter positioned within the fire extinguisher proximate the fire extinguisher outlet burst disc. The fire extinguisher actuator assembly also includes a motorized activation device having a drive shaft. The motorized activation device is operable to rotate the drive shaft and push the cutter to pierce the fire extinguisher outlet burst disc, thereby releasing the pressurized fire extinguishing agent through the discharge head.

  • Patent number: 9649520
    Abstract: According to one aspect, a fire extinguisher actuator assembly for a fire extinguisher is provided. The fire extinguisher includes a fire extinguisher reservoir and a burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent within the fire extinguisher reservoir. The fire extinguisher actuator assembly includes a cutter shuttle assembly having a cutter coupled to a shuttle body. The cutter shuttle assembly is detained within the fire extinguisher proximate the burst disc and biased to form a pressure equalization region between the shuttle body and the burst disc. The fire extinguisher actuator assembly also includes an activation device having a piercing member operable to pierce the burst disc and release pressure from the pressure equalization region, thereby driving the cutter through the burst disc to release the pressurized fire extinguishing agent through the discharge head.

  • Patent number: 9539452
    Abstract: According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent at an internal fire extinguisher pressure within the fire extinguisher reservoir. A cutter is detained within the fire extinguisher proximate the fire extinguisher outlet burst disc. An interior container within the fire extinguisher reservoir has a container pressure and is sealed with a container burst disc. An activation device having a piercing member is operable to pierce the container burst disc and diffuse the container pressure to create a pressure differential relative to the internal fire extinguisher pressure at the cutter, thereby driving the cutter through the fire extinguisher outlet burst disc to release the pressurized fire extinguishing agent through the discharge head.

  • Patent number: 9038742
    Abstract: An exemplary suppressant actuator assembly includes a release member movable from a first position that restricts flow of a suppressant to a second position that permits flow of a suppressant. A biasing member moves from a more-biased position to a less-biased position to move the release member from the first position to the second position. A solenoid is activated to permit movement of the biasing member.
