Abstract
An apparatus (10) for inflating an inflatable device (8) includes a container (12) defining a chamber (14) containing gas. The container (12) includes a rupturable wall (24) which is rupturable when the pressure in the container reaches a predetermined level. An igniter (46) spaced from the rupturable wall (24) produces a shock wave in the gas which ruptures the rupturable wall (24) prior to the gas pressure in the container (12) reaching the predetermined level.
