Abstract
A fire extinguisher includes a main dome surrounding an interior. An internal plate is mounted inside the interior of the main dome, dividing the interior into an internal space housing agent and a secondary internal space. The internal space housing agent and the secondary internal space are both pressurized above ambient. The secondary internal space is free of agent, and can be pressurized, e.g., to no less than the total pressure of the internal space housing agent.
Claims15
A fire extinguisher comprising:
- a main dome surrounding an interior;
- and
- an internal plate mounted inside the interior of the main dome, dividing the interior into an internal space housing agent and a secondary internal space, wherein the internal space housing agent and the secondary internal space are both pressurized above ambient.
A method of fire extinguishing comprising:
- storing fire extinguishing agent at pressure inside a main dome of a fire extinguisher wherein a first internal space inside the main dome houses the agent and a secondary internal space inside the main dome is pressurized to reduce pressure differential across an internal plate that separates the internal space housing agent from the secondary internal space;
- and
- discharging all or almost all of the agent through one or more outlet fittings laterally.
