ABSTRACT:
A pyrotechnic device having an ignition delay between a fuse or igniter and a device to be ignited, including a first element which defines a first space that houses at least one fuse or igniter, and a second element which communicates with a second space that houses the device to be ignited, moreover, the device includes a track containing an evenly burning flammable material, which is in permanent contact with the first space by a connecting portion of the first space and with the second space by an opening. The first element can slide in relation to the second element and/or vice versa such as to alter the length of the track between the connecting portion and the opening, in order to modify the duration of the ignition delay.
