DEVICE FOR INITIATION OF IMPACT-WAVE PIPE AND ELECTRIC DETONATORS WITH REMOTE ACTUATING ELEMENT Russian patent published in 2011 - IPC F42D1/04 F42B3/10 

FIELD: miming.

SUBSTANCE: device for initiation of impact-wave pipe includes housing performed in a form of threaded connection of two parts, foundation and nozzle. At housing foundation there installed is dielectric bush with central contactor necessary for provision of plug-type connection with inner electrode of replaceable discharger that consists of outer electrode in a form of a bush with tip of conical shape. Inside the tip there installed are inner electrode and dielectric isolator with the possibility of generating electric discharge that initiates impact-wave pipe. Dielectric isolator is located between inner and outer electrodes. Inner electrode is performed in a form of a needle and projects in relation to outer electrode tip with formation of spark gap equal to 0.15 mm. Nozzle has a through hole for axial location of impact-wave pipe and replaceable discharger in it from opposite sides, replaceable discharger is fixed along central axis and through the pad, that provides tightness of plug-type connection from penetration of combustion products, it is pressed to housing foundation for provision of contact with replaceable discharger outer electrode.

EFFECT: reliable initiation of impact-wave pipe and possibility of faulty replaceable discharger quick change.
