Abstract: An inflator (20) having a body (22) including a first combustion chamber (110) and a second combustion chamber (112) and a plurality of exit orifices (90); a quantity of first propellant (150) within the first combustion chamber and a quantity of second propellant (180) within the second combustion chamber (112), the second propellant producing inflation gas as it combusts; a separator (100) from the first combustion chamber into the second combustion chamber; the body (22) proximate the second combustion chamber (112) including a plurality of control orifices (90); a flow means (70) for causing inflation gas exiting the control orifices to flow through an arcuate path between the control orifices and the exit orifices (30); a heat sink (230) and (234) for changing the physical state of at least one gaseous component of the inflation gas to a liquid and a solid prior to this component exiting the exit orifices.
