一个燃气发生器,它包括一个壳体和一个放在壳体里的固体推进剂结构、以及一个安置在壳体和推进剂之间的沸石阻挡层。沸石阻挡层可以用在其中嵌入粉末沸石的橡胶板,也可以用装有颗粒状沸石的带孔容器。嵌入沸石的橡胶板,也可以嵌入能起到象吸水芯一样作用的纤维。这个发明叙述关于改善能源装置以及对于控制燃气发生器中使用的硝酸铵推进剂的尺寸变化的更显著意义。装着产生燃气的固体火药的燃气发生器,以前被利用来做为原动机运转的动力源。例如,内燃机、电动机起动器、开关的闭合、喷气发动机起动器等等。这些燃气发生器通常由一端开口而另一端闭合的园柱形壳体组成,在壳体里装着一个点火装置和一个设计较好的固体装药,在壳体和装药之间安放着密封防潮装置。
A gas generator includes a housing and a solid propellant structure disposed within the housing, and a zeolite barrier disposed between the housing and the propellant. The zeolite barrier may be a rubber plate in which powdered zeolite is embedded, or a perforated container containing granular zeolite. The rubber sheets embedded in the zeolite can also be embedded in fibers that act like absorbent cores. This invention recites the more significant significance of improving energy installations and of controlling the dimensional changes of ammonium nitrate propellants used in gas generators. Gas generators fitted with gas-producing solid gunpowder were previously used as the motive power for prime mover operation. For example, internal combustion engines, motor starters, closing of switches, jet engine starters and the like. These gas generators typically consist of a cylindrical housing with one end open and the other closed, with an ignition and a well-designed solid charge in the housing, with a moisture-tight seal between the housing and the charge Device.
