    • The invention relates to a device serving for repeated production of explosions. The device comprises: an explosion chamber (11), a feed line for feeding a free-flowing explosive material, a vent opening for directed venting of a gas pressure produced by ignition of the explosive material in the explosion chamber (11), and a movable closure element (21, 31) for partial or complete closure of the vent opening (17). The device has an outlet nozzle (15) having a nozzle inlet area (13) and a nozzle outlet area (14), and has an adjustment device (23). The adjustment device (23) is designed such that, after the vent opening (17) is opened and explosion gases flow out through the outlet nozzle (15), an area ratio between the nozzle inlet area (13) and the nozzle outlet area (14) is adjusted to at least approximately correspond to an ideal area ratio for producing a maximum exit velocity of the explosion gases as a function of the pressure in the explosion chamber (11).
    • 用于重复产生爆炸的装置包括爆炸空间,用于馈送可流动的爆炸性材料的进料管道,用于定向排放由爆炸空间中的爆炸物质点燃产生的气体压力的排放口,以及 用于部分或完全关闭排放口的活动闭合元件。 该装置包括具有喷嘴入口区域和喷嘴出口区域的出口喷嘴以及致动装置。 致动装置适于在排出口打开和爆炸气体通过出口喷嘴流出之后,调节喷嘴入口区域和喷嘴出口区域之间的面积比。 根据爆炸空间中的压力,面积比至少近似于产生爆炸气体的最大出口速度的理想面积比。
