发明名称 DETONATOR WITHOUT PRIMARY EXPLOSIVE
摘要 safety means of explosion, in particular, electric detonators, as well as detonators with a delay for systems of non-electric explosion. SUBSTANCE: detonator without primary explosive has a body, ignitable element, intermediate shell of different section facing it with the narrow portion, low-density high-explosive charge, high-density high-explosive charge, all positioned in succession in the body. The intermediate shell is made in the form of aligned cylinders with a diameter increasing towards the high-density high-explosive charge, the narrow portion of the intermediate shell is filled with incendiary material that is separated from the next following ignition compound by an indestructible membrane, then follows the low-density high-explosive charge positioned both in the intermediate shell and in the detonator body before the high-density high-explosive charge. For stabilization of the flow of products of operation of the ignitable element a damping sleeve may be placed between the ignitable element and the outlet of the intermediate shell, the sleeve inner surface is made in the form of two cones connected by vertices. A retarding agent may be positioned in the narrow portion of the shell before the incendiary material. EFFECT: enhanced reliability of operation and simplified design. 3 cl, 3 dwg
