ABSTRACT:
The air bag inflator is particularly useful for mounting in a steering wheel of a vehicle for inflating an air bag. A magnetic control unit is disposed concentrically of an injection piston through which liquid propellant is injected from a liquid propellant chamber into a combustion chamber. In one embodiment, the injection piston and pump piston are contoured to define a contoured liquid propellant chamber. In a second embodiment, an annular injection piston is slidably mounted on an annular pump piston to define an annular liquid propellant chamber.
