Patentansprüche:Patent claims: 1. Vorrichtung mit explosiven Hohlladungen für Durchlochungen, Unterteilungen od. dgl., insbesondere zum Perforieren von Verrohrungen in Tiefbohrlöchern, mit einem Hohlkörper, in dessen Innerem die Ladungen untergebracht sind, dadurch gekennzeichnet, daß in den mit Luft oder Gas angefüllten Kammern, die diese Ladungen umgeben, Körper vorgesehen sind, die die schlagartige Wirkung der Explosionswelle herabmindern.1. Device with explosive shaped charges for perforations, subdivisions or the like, especially for perforating casing in deep boreholes, with a hollow body, in the interior of which the charges are housed, characterized in that in the with Air or gas-filled chambers that surround these charges, bodies are provided, which reduce the sudden effect of the explosion wave. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Körper aus rauhen porösen Stoffen (Gummischwämme, Filze, Glaswolle usw.) oder plastischen Stoffen (wie Polystyrole, Polyvinyle, Nylons usw.) mit rauher Oberfläche oder auch aus metallischen Geweben bestehen.2. Device according to claim 1, characterized in that that the bodies are made of rough porous materials (rubber sponges, felt, glass wool, etc.) or plastic materials (such as polystyrenes, Polyvinyls, nylons, etc.) with a rough surface or made of metallic fabrics exist.
