First Claim
Patent Images
1. An apparatus for extinguishing fire in a confined compartment having a normal flow of ventilating air therethrough, said apparatus comprising:
- an inflatable bag mounted in a collapsed condition adjacent the compartment, said bag being configured to be compatible with volume and space geometry of the compartment and having means for dispersing a gaseous or vaporizable liquid fire extinguishing agent;
a normally deactivated source of said gaseous or vaporizable liquid fire extinguishing agent connected to said bag;
and means operatively connected to said source to activate release of said gaseous or vaporizable liquid fire extinguishing agent for inflating the bag resulting in blockage of the normal flow of the ventilating air, displacement of at least a portion of residual air, and dispersal of said agent through the bag into the compartment to effect fire extinguishment.

Abstract
A fire extinguishing apparatus for use in normally ventilated or confined spaces of, for example, vehicles, such as an aircraft engine compartment, has an inflatable bag to enhance extinguishing agent performance. The inflatable bag is connected to a source of gaseous or vaporizable liquid fire extinguishing agent which upon discharge flows to the bag resulting in its deployment into the compartment. The bag is configured to block the normal compartment ventilating air path while allowing for dispersal of agent from the bag into the compartment to effect extinguishment.
