IGNITION DEVICE Russian patent published in 2005 - IPC

FIELD: initiation means, in particular, ignition means of pyrotechnical compounds and powders, in pyrotechnical or powder pressure sources used in industry.

SUBSTANCE: the ignition device has two pyrotechnical charges - an initiating and an igniting ones, located in the body coaxially through a partition in which holes are made for transmission of burning. The initiating charge is installed in contact with the partition, and the igniting charge is installed with a clearance to the partition. Both pyrotechnical compounds are thermoresistant and large calorie compounds. The initiating charge is ignited either by heating of the bridge by electric current, or by a fire pulse. The combustion products of the initiating pyrotechnical compound are in the gas phase, and those of the ignition pyrotechnical compound are in the gas and solid phases.

EFFECT: enhanced thermal stability (approx. 300°C), reliability of initiation of the working charge, leak-proofness, simplicity.
