An inflator assembly (10) for inflating an inflatable vehicle occupant restraint (12) includes a pressure vessel (14) with a storage chamber (18) containing a combustible mixture of gases. An ignitable material (122), when burning, ignites the combustible mixture of gases in the storage chamber (18). The storage chamber (18) has an axis (61), first and second opposite ends which are spaced from each other a distance along the axis (61), and a substantially circular cross sectional shape at all locations along the axis (61). The storage chamber (18) has a shape such that the ratio of the distance between the opposite ends of the storage chamber (18) to the greatest cross sectional diameter of the storage chamber (18) is within the range of 0.75-1.25.
