    摘要: The present invention relates to an inflator for a safety device, in particular for a vehicle occupant restraint system, comprising a housing (1, 15; 22, 23), a combustion chamber formed in the housing and including a solid propellant (6) for generating hot gas, and a coolant (13) introduced into a predetermined flow path of the hot gas. The inflator in accordance with the invention is characterized in that the flow path of the hot gas passes through a nozzle (10) comprising a pitot zone (20) in which the hot gas emerging from the combustion chamber (21) has a high static pressure, and comprising a nozzle neck (19) in which the hot gas builds up a high dynamic pressure, and in that the coolant (13) is arranged in a sleeve-shaped reservoir (11) extending from the pitot zone (20) at least in part into the nozzle neck (19). The inflator in accordance with the invention permits an effective reduction in the exhaust gas temperature of the generated hot gas.

    摘要: A gas generator comprises a tubular housing of a pressure-resistant material and a propellant strand incorporated in the housing. The propellant strand is provided with an envelope surrounding the propellant strand. The envelope is dimensionally stable and substantially rests against the entire outer surface of the propellant strand. The envelope is formed such that in the case of an increase in pressure it expands and rests against the inner surface of the housing.
