INITIATION DEVICE Russian patent published in 2003 - IPC

FIELD: blasting operations, blasting equipment, applicable in blasting circuits for transmission of detonating pulse in one direction, in the constructions of primers or pressure sources. SUBSTANCE: the body has two aligned ducts separated by an undestructible obstacle and positioned on the opposite sides of the intersecting plane passing through the obstacle, the receiving charge is positioned in one duct, and the other is designed for the transmitting charge. The obstacle thickness is chosen proceeding from the following relation: Δ_ob/d_rec.ch = 1,1-1,5, where d_rec.ch - the diameter of the receiving charge (mm); Δ_ob-obstacle thickness (mm). The ignition gas generating charge may be installed past the receiving charge. The receiving charge may be made of pyrotechnic compound. EFFECT: enhanced reliability of device sealing after operation, optimized mass and dimensional characteristics. 3 cl, 2 dwg
