Title:
GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2014/208290
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a pressurized gas-based gas generator that has a simple mechanism for breaking a sealing member and is capable of reliably opening a gas-discharging path. The present invention provides a gas generator (10) wherein a cylindrical housing (11) is formed from an ignition means chamber housing (30) and a pressurized gas chamber housing (20). A piston (50) which can slide in an axial direction is installed inside the ignition means chamber (32).
The piston (50) is equipped with: a base section (51) which can slide along the inner circumferential surface (30a) of the ignition means chamber (32); and a projectile section (52) which has an outer diameter smaller than the outer diameter of the base section (51) and can break away from the base section (51). The projectile section (52) breaks away from the base section (51) and flies further into the pressurized gas chamber (22) after colliding against a sealing member (15), thereby opening the sealing member (15).
