    • Gas generator for an inflatable impact cushion for protecting an occupant of a motor-vehicle from injury, has a housing, in which is formed a storage chamber for liquid gas. The storage chamber is separated by a partition wall from a combustion chamber also formed in the housing. An ignition device is positioned in a precombustion chamber, and has an ignition charge to generate combustion gases during ignition. In the precombustion chamber there is guided, in a displaceable manner, a piston which, because of the combustion gases of the ignition charge, moves into and through the combustion chamber in a direction of the partition wall, in order to penetrate the partition wall. When the partition wall is penetrated there is a connection between the storage chamber and the combustion chamber by way of a liquid gas channel system so that liquid gas can flow into the combustion chamber. At the same time a connection is created between the precombustion chamber and the (main) combustion chamber by way of ignition channels formed in the piston. The hot combustion gases of the ignition charge ignite the liquid gas flowing in. The rising internal pressure in the combustion chamber causes a displacement of the longitudinally displaceably guided partition wall, which moves together with the piston and thereby continuously injects liquid gas from the storage chamber into the combustion chamber. The combustion gases emerge by way of annular chambers, connected in series, through outlet openings in the housing.
    • 用于保护机动车辆乘员免受伤害的可充气冲击缓冲器的气体发生器具有壳体,其中形成有用于液体气体的储存室。 存储室由也形成在壳体中的燃烧室的分隔壁分隔开。 点火装置定位在预燃室中,并且具有点火充电以在点火期间产生燃烧气体。 在预燃室中以可移动的方式引导一个活塞,该活塞由于点燃电荷的燃烧气体沿分隔壁的方向移入和穿过燃烧室,以便穿过分隔壁。 当分隔壁穿透时,通过液体气体通道系统在储存室和燃烧室之间存在连接,使得液体气体可以流入燃烧室。 同时,通过在活塞中形成的点火通道在预燃室和(主)燃烧室之间形成连接。 点火装置的热燃烧气体点燃流入的液体气体。燃烧室中的上升内部压力引起纵向可移动地引导的分隔壁的位移,其与活塞一起移动,从而连续地从储存室喷射液体气体 进入燃烧室。 燃烧气体通过环形室,通过壳体中的出口开口串联连接。

    • A partially combustible propellant charge igniter has a bottom piece with primer charge and an ignition gas guide tube adjoining this primer charge, with a combustible tube containing the booster charge, the internal diameter of this latter tube being larger than that of the ignition gas guide tube, and a cavity containing a separating charge between the ignition gas guide tube and the combustible tube. A communicating opening is provided between the propagation charge and the separating charge. The communicating opening comprises at least one bore in a valve bonnet, valve means being provided which, in case of excess pressure in the cavity with respect to the booster charge close the bores at least partially, so that ignition of the separating charge takes place essentially through the bore.

    • A flash guide tube arrangement utilized primarily in propellant charge igniters for large-caliber ammunition with laterally located openings from which the ignition gases, emitted by conventional ignition systems, exit, either for the ignition of an ignition booster charge or for the direct ignition of a propellant charge. Indentations emanate axially from these openings and extend into the interior of the flash guide tube, the depth of the individual indentations decreasing in the direction toward the rear end of the flash guide tube. The indentations are preferably radially arranged and several of such radially disposed indentations can be provided in the flash guide tube. The rear end of the flash guide tube can furthermore be constructed as a cone having its apex pointing toward the ignition system.

    • A pyromechanical cutting element has a housing (2) in which an electrical conductor (3) is arranged, a cutting plunger (5) with a cutting tool (8) to cut through the electrical conductor (3), and pyrotechnic charge (13) to drive the cutting plunger (5), with the cutting tool (8) bending over the electrical conductor (3) after cutting through it and forming a bending tongue (18) that sticks out from the conductor (3) in a way that interrupts the conductor (3). The electrical conductor (3) has a cross-sectional area reduction in the longitudinal direction (4) consisting of two transverse sides and two longitudinal sides. The cutting tool (8) first cuts through the cross-sectional area reduction (4) just on one transverse side and upon further advancement bends over the longitudinal sides at least in part, and, upon further advancement, the cutting tool (8) clamps the bending tongue (18) thus created.
