Defense device, preferably self-defense device and storage unit used therein.

摘要

The accumulator unit (1) with a powder, gaseous or liquid material stored in an accumulator space (5). A propellant is ignited by a fuse composition to drive the material through a nozzle unit (3) into free space by a propellant gas after ignition. A closure element (19) in the nozzle entry area prevents material from coming out of the accumulator space without ignition and is released directly after ignition so that no parts of the broken closure element are pushed out of the nozzle unit. A piston (21) in the accumulator space is moved by the propellant gas to drive the material through the nozzle. A pressure relief device co-operates with the piston. An Independent claim is included for a self-defence device including at least one pair of accumulator units.
