Abstract
The technical field of the invention relates to devices providing for the ejection of a plurality of payload elements from the casing of a carrier shell. The ejection device according to the invention includes a pyrotechnic composition placed in a head and intended to create, after ignition, a gas pressure that pushes a piston over a short distance so as to displace towards a base a moving assemblage having a pusher plate and payload elements, and to eject the base, the piston then being stopped relative to the head and having an orifice which allows the gases to pass towards the moving assemblage so as to push the latter. The device includes braking means disposed between at least a part of the moving assemblage and the shell casing. This invention is applicable to mine-dispersing carrier shells.
