An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture of COand Ndisposed within the canister and a gaseous fire suppression agent disposed in the canister.

N2/CO2 fire extinguishing system propellant gas mixture

An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture disposed within the canister; and a gaseous fire suppression agent disposed in the canister, wherein a diameter of the outlet port is sized relative to a pressure of the propellant gas mixture.

Automatic fire extinguishing system having outlet dimensions sized relative to propellant gas pressure

An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube having dip tube side holes and inlet openings, and disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture disposed within the canister and a gaseous fire suppression agent disposed in the canister.

Automatic fire extinguishing system with internal dip tube

A valve mechanism is herein described that utilizes a frangible plug. The valve mechanism comprises a valve body having an inlet port and an outlet port and a passageway extending therebetween. The valve mechanism comprises a frangible plug that is held within the valve body to block the passageway when the plug is intact. The plug comprises a predefined fracture plane and is configured to fracture across the predefined fracture plane upon application of an impact force.
