International ClassA62C 003/08AbstractA 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.Field of SearchAPPARATUS WHICH ISOLATES FLAMES FROM NON-BURNING AREASPECIAL APPLICATIONS Sensor, control and actuator Electrical control For vehicles For mine Resilient or deformable terminal outlet MISCELLANEOUS (E.G., RESILIENT NOZZLE) Fire prevention devices With safety device Emergency smoke or fire responsive valve | |
