摘要： A liquified gas-containing generator has a casing in which a reaction container containing liquified gas is accommodated. So as to trigger combustion of the liquified gas a puncture element with an overflow channel is driven into the reaction container. The kinetic energy for the puncture element is generated pyrotechnically by initiation of an ignition element. The ignition gases of the ignition element pass via the overflow channel into the interior of the reaction container where these gases induce combustion of the liquified gas. The combustion gases arising thereby pass via the overflow channel out of the reaction container into a hollow space in which the puncture element is arranged. The hollow space is sealed in relation to a discharge passage by a bursting membrane. This bursting membrane bursts open when a minimum pressure of the combustion gases is reached and thereby opens the way for discharge of the combustion gases out of the casing via the discharge passage.
