Opening device for a pressurized gas container's outflow opening sealed by a membrane, particularly for a clean-gas generator to inflate an airbag, uses a plunger moved by super pressure

摘要

A plunger (7) fits on a low-pressure side of a pressurized gas container (1) and has such a shape that it punches a membrane (5) out on its edge on one side, and, on the other side, when punched out, the membrane is pressed against the plunger by super pressure in the pressurized gas container and fixed by the plunger.
