An airbag inflator includes a pair of telescoping pistons slidingly mounted within a housing. Pressurization of a combustion chamber by a pyrotechnic initiator acts on one piston to pressurize a hydraulic fluid chamber, which, in turn, acts on the other piston to pressurize a liquid propellant reservoir. Liquid propellant can then be regeneratively pumped from the reservoir into the combustion chamber for combustion to generate an airbag inflation gas. A hydraulic fluid damping chamber is utilized to exert a controllable retarding force on the one piston...
[ What is claimed is:] [1.] An airbag inflator comprising:a housing;first and second pistons in telescoping relation to one another and mounted for axial sliding motion within the housing;a combustion chamber within the housing;a reservoir within the housing containing a liquid propellant;an injection orifice, through which the liquid propellant may flow from the reservoir into the combustion chamber;a coupling chamber within the housing containing a hydraulic fluid exposed to the first and second pistons; anda pyrotechnic initiator within the housing op...
