Charge delayed ignition device for combat engineer - has ignition circuit with parallel delay elements and parallel ignition capacitors

摘要

The ignition circuit uses two parallel delay elements (4,4') and two parallel ignition capacitors (2,2'). The parallel delay elements (4,4') are coupled across the current source (5) by actuating the release switch (7) and they are connected in parallel with the two parallel ignition capacitors (2,2') via a series load resistance (3). The delay elements (4,4') control an electronic switch (6) in series with the ignition element (1) across the ignition capacitors (2,2'). The parallel circuits may be coupled to the current source via a voltage converter, e.g. to allow the ignition capacitor circuit (2,2') to be supplied with 50 volts from a 7 volt battery.
