An inflator having a combustion chamber and a stored gas chamber separated by a bulkhead. The bulkhead includes a flow passage extending between the combustion chamber and stored gas chamber, with a plurality of exit ports opening onto the flow passage. A flow plug is initially received in the flow passage to block the flow of the stored gas from the stored gas chamber. Activation of the inflator causes increased pressure in the combustion chamber, which forces the flow plug from the flow passage to permit the stored gas to flow through the exit ports, and for the heating gas from the combustion chamber to mix with the stored gas. A head flange may be formed on the flow plug to permit the stored gas to begin exiting the stored gas chamber prior to mixing with the heating gas. A slide nozzle may also be interposed between the flow plug and flow passage to form a nozzle forcing the heating gas to mix with the stored gas prior to exiting the inflator.
