Ignition system for a fluid-fueled inflator
 An improved ignition system for inflators such as those used in airbag passive restraint systems is disclosed. A breakable seal is provided in a storage chamber for a combustible fluid. Upon activation of an initiator the breakable seal is opened and the combustible fluid flows from the storage chamber into a combustion chamber where it is ignited to provide an enhanced volume of heated gas. The heated gas may be used either to directly inflate an associated inflatable apparatus or it may be used to first heat a further compressed gas and the combined gases used to inflate an inflatable apparatus. The breakable seal may be opened by a piston driven plunger. The design of the components of the ignition system provides control over the inflation characteristics.
