  "textContent": "The air bag inflator employs an injection piston assembly in which liquid propellant is delivered through nozzles in the injection piston (18) to the combustion chamber (12). Metering of the liquid propellant is accomplished in a manner that is not sensitive to changes in ambient temperatures. A plug (28) is slidably mounted between the propellant chamber (22) and the nozzles (25) to prevent flashback at startup. The plug (28) is pushed forwardly to expose the nozzles (25) to the propellant chamber (22) in response to a predetermined pressure in the propellant chamber (22). A plug may also be fitted into each nozzle to be expelled into the combustion chamber upon opening of the nozzle. A tape (27) may also be provided over the outlet of the nozzle to prevent flashback into the propellant chamber.",
