INFLATOR

摘要

An inflator, wherein a charge holder (37) providing a directivity to a detonation wave caused by the combustion of igniting powder (36) is installed in an igniter (26) to facilitate the rupture of a rupture disk (19), since a crossed flaw is provided in the surface of the rupture disk (19), the rupture plate (19) is curled at four positions when the rupture plate receives a burst pressure caused by the igniter (26) to assure the outflow of pressurized medium and prevent fragments from occurring, an existing gas cylinder can be used for an inflator housing (12) since the inflator housing can be connected to a diffuser (20) by screwing the male screw part on the outer end surface of the inflator housing (12) with the female screw part on the inner end surface of the diffuser part (20), the opening part side of a housing (321) is connected to a diffuser part (320), a gas discharge port is connected to the diffuser part, and the axial directions of an inflator housing (312) and a gas discharge port (340) are identical to each other, and the opening part side of an inflator housing (512) is connected to a diffuser part (520), a gas discharge port (540) is connected to the diffuser part (520), and two filter means are disposed.
