Definitions

  • Requirement DE 102009058049 discloses a pneumatic projectile launcher having a single constant volume compressed gas reservoir for propelling the projectile retained by a wedging means to a pressure-determined range.
  • the object of the invention is to allow precise adjustment of the range of the projectile without having to precisely dose the pressure in a secondary reservoir of pneumatic weapon.
  • the secondary reservoir has an opening substantially the same diameter as a launching tube, the launch tube being positioned directly opposite the opening, the rapid expansion means comprising a closure plug tube which is solidarisable with the rear part of the projectile and which can be connected to the tube by a releasable locking means.
  • the ring may be integral with a collar ring which will slide on the tube and will bear against a shoulder of the tube in the locking position, a spring being interposed between the ring and the shoulder to maintain the ring in locking position.
  • a firing device 1 according to the invention comprises two parallel tubes 10a and 10b each comprising a projectile 9.
  • the upper tube 10a is able to feed with compressed gas contained in the secondary reservoir 6.
  • the ring 63 has in its internal part at least one internal groove 64 intended to be placed in front of the bore 54 and to receive all or part of the ball 52 when the firing is triggered as visible at the figure 3 (lower part).
