Hybrid blowdown inflator with reduced pressure buildup
 A hybrid inflator for a vehicle airbag module produces an initial release of essentially unheated, stored, pressurized gas from the gas storage chamber of the inflator by way of a projectile, releasable from a nozzle opening in a combustion chamber housing upon combustion of a gas-generating combustible material housed within the combustion chamber housing, which ruptures and passes through a frangible burst element retaining the stored, pressurized gas in the gas storage chamber of the inflator, thereby permitting, initially, the unheated, stored, pressurized gas to discharge through the ruptured burst element and flow externally past the combustion chamber housing in an isolation housing and then to exit the inflator through gas exhaust ports in the inflator.
