INITIATOR Russian patent published in 2017 - IPC F42C19/00 F42B3/10 

FIELD: blasting works.

SUBSTANCE: device comprises the detonator with the explosive charge and it is displaced from its axis by the initiation element and the detonation channel between the detonator and the detonation object. The detonator is located laterally along the surface of the detonation object, the detonation channel is bent and consists of two sections. The first section faces the detonator and is placed at the angle to its axis. The second section faces the blasting object. The axis of the first section intersects the detonator axis in the channel end surface center. The channel sections clamping edge lower part from the detonation object side is rounded by the radius from 1 up to 2 radii of the detonation angular distribution area in the channel so, that the rounding surface in the device plane of symmetry is tangential to the detonator axis.

EFFECT: initiator operating time is stabilized, measurements quality of the detonation object operation temporary characteristics is improved, operational and layout characteristics of the detonation object are improved.
