The invention relates to the technical field of automobile safety air bags, in particular to a gas generator and an automobile. The gas generator comprises a shell, a filtering piece and a gas assembly; the shell is provided with an inner cavity; the filter part is contained in the inner cavity and divides the inner cavity into a first chamber and a second chamber, and the first chamber is located above the second chamber; the gas assembly is accommodated in the second chamber; a plurality of exhaust ports for communicating the first cavity with the outside are formed in the top of the shell, and the opening area of each exhaust port is gradually reduced in the direction from the first cavity to the outside. According to the gas generator, the internal pressure of the gas generator can be adjusted according to the temperature change, so that the use performance of the gas generator is improved, the performance difference of the gas generator at different temperatures is reduced, and the stability of the gas generator is improved.

    本发明涉及汽车安全气囊技术领域,具体而言,涉及一种气体发生器和汽车。气体发生器包括壳体、过滤件及气体组件;壳体具备内腔;过滤件容置于内腔,且将内腔分隔为第一腔室及第二腔室,第一腔室位于第二腔室上方;气体组件容置于第二腔室;壳体的顶部开设有多个将第一腔室与外界连通的排气口,且由第一腔室至外界的方向,每个排气口的开口面积均逐渐减小。气体发生器能够根据温度的变化调整气体发生器的内压,从而改善气体发生器的使用性能,减小气体发生器在不同的温度下的性能差异,进而提高气体发生器的稳定性。
