DIVERSIONARY DEVICE

摘要

A diversionary device has a housing containing a pyrotechnic cartridge with an ignitable fuse. A firing arrangement includes an ignition cap containing a primer charge. Passageways in the housing and ignition cap define a first flow path from the primer charge to a region of the housing in which the fuse is located through which flash from the primer charge can flow to ignite the fuse. A further flow path connects said region of the housing with the exterior of the housing to supply the fuse with oxygen for reliable burning. The device may be a multi-burst device containing a plurality of cartridges and the first flow path may include a flash divider for directing a proportion of the flash from a primer charge on to the fuse of each cartridge. The housing may be separable to allow replacement of the cartridges.

1. A diversionary device comprising a housing having an outer housing portion defining an internal cavity, at least one replaceable pyrotechnic cartridge mounted in the housing and at least partly located within the internal cavity, the cartridge having a first end containing an ignitable fuse, the housing defining a region in which the first end of the at least one cartridge is located, a firing arrangement mounted to the housing and including an ignition cap containing a primer charge, the housing and ignition cap defining a first flow path from the primer charge to the housing region to provide a fluid path through which a proportion of a flash of heat and pressure given off by a primer charge in the ignition cap when it is fired is can flow to ignite the fuse, in which a further flow path is provided to fluidly connect the housing region with the exterior of the housing.
