Patent ID: 7735571

Claim:
An extinction device, comprising: a gas generator comprising an enclosure equipped with a gas outlet port and a block of pyrotechnic material that generates propellant gas, wherein the propellant gas generated from the block of pyrotechnic material is the only gas generated by the extinction device as an extinguishing gas; a filter positioned downstream from the pyrotechnic material within the enclosure and configured to cool the propellant gas; means for distributing said propellant gas coupled to the gas outlet port; and means for regulating pressure created by said propellant gas in the distribution means, wherein the block of pyrotechnic material includes a propellant configured to be ignited by an ignition device such that the propellant gas is generated from the block of pyrotechnic material by ignition, and wherein the gas generator is configured to have a booster phase, during which the propellant gas has a volume flow rate of 1.05 m 3 /s, and a maintenance phase, during which the propellant gas has a volume flow rate of 0.05 m 3 /s.
