INITIATING DEVICE WITH DELAY OF ACTUATION Russian patent published in 2020 - IPC F42B3/10 F42B3/16 F42C19/08 

FIELD: pyrotechnics.

SUBSTANCE: invention relates to pyrotechnics and can be used to provide temporary delays in designs of igniters, for example, for pressure sources, gas generators, in pyroautomation systems for mechanical movement of structural elements, for engagement of fire circuit of fuses, etc. Device includes a housing with two coaxial channels separated by one indestructible barrier, one of which is intended for arrangement of transmitting charge, and the other is to accommodate successively slow charge from pyrotechnic composition, intermediate and located in the cap of the accelerating gas-generating charge, wherein the free space between the cap and the end surface of the body is filled with incompressible inert material which is polymerized after casting, flush with the housing end.

EFFECT: high accuracy of operation of the device and improved manufacturability thereof.
