First Claim
Patent Images
1. A fire suppressing gas generator comprising:
- a housing comprising at least two discharge ports distributed thereon;
a filter disposed within the housing and spaced from an interior wall of the housing;
at least one propellant grain inside the filter; and
at least one ignition device associated with the at least one propellant grain;
wherein the at least one propellant grain, when ignited by the at least one ignition device, generates a fire suppressing gas which passes through the filter and out of the at least two discharge ports of the housing for delivery into a space, andwherein the distribution of the at least two discharge ports on the housing provides substantially thrust neutrality to the generator when the fire suppressing gas passes out of the at least two discharge ports.

Abstract
A fire suppressing gas generator includes a cylindrical housing comprising an array of discharge ports distributed generally uniformly therearound; a cylindrical filter disposed within the housing and spaced from the interior wall of the housing; a plurality of azide-based propellant grains inside the cylindrical filter; and at least one ignition device associated with the propellant grains. The propellant grains when ignited by the ignition device generate a fire suppressing gas which passes through the filter and out of the discharge ports of the cylindrical housing for delivery into a space.
