HYBRID GAS GENERATOR

摘要

The present invention discloses a hybrid gas generator, comprising: a high pressure gas cylinder (1), a gas release actuating device comprising a pyrotechnic gas cylinder (3) and an igniting assembly (4), and a bursting disc (2). The pyrotechnic gas cylinder (3) may further comprise: a guide ring (5) securely disposed in the pyrotechnic gas cylinder (3) to hermetically separate the space therein into a gas releasing chamber (311) and a firing chamber (312), a piercing plug (6) fitted with the guide ring (5), where the gas releasing chamber (311) is formed with at least a vent (313) for releasing the gas stored in the high pressure gas cylinder (1), and the firing chamber (4) may be provided with gas producing medium to produce gas for driving the piercing plug (6) when the igniting assembly (4) may be ignited.
