Abstract
A hybrid gas generator includes a high pressure gas cylinder and a gas release actuating device. The gas release actuating device includes a pyrotechnic gas cylinder, an igniting assembly, and a bursting disc. The pyrotechnic gas cylinder includes a guide ring securely disposed in the pyrotechnic gas cylinder to hermetically separate the space in the pyrotechnic gas cylinder into a gas releasing chamber and a firing chamber, a piercing plug fitted with the guide ring, where the gas releasing chamber is formed with at least a vent for releasing the gas stored in the high pressure gas cylinder, and the firing chamber may be provided with a gas producing medium to produce gas for driving the piercing plug when the igniting assembly is ignited.
