  • CH 229 678 A discloses a gas pressure supercharger in which the gas piston influenced by the tapped gases of the barrel surrounds the barrel in a sleeve-like manner and brings the closure for unlocking and returning after the shot via rods or the like.
  • the gas piston is designed here so that it surrounds the rear end of the barrel and also as a support member which can be locked with the barrel closure piece.
  • a drive system for a gas pressure loader which comprises at least two gas piston systems. These are aligned parallel to the barrel and arranged mirror-symmetrically to the longitudinal section plane of the Gas horriaders.

  • the proposed closing springs are in turn involved at the rear end of the closure.
  • DE 10 2005 062 758 B relates to a gas take-off arrangement for the weapon barrel, the running bore of which is in communicating connection with a gas cylinder, which is provided with a first gas outlet opening, which cooperates with a throttle element. Run, gas cylinder, first gas outlet opening and throttle element are formed so that a temperature-induced change in length of the barrel causes a relative movement between the gas cylinder and the throttle element.
  • closing springs and drive elements are housed in a common housing, the weapon housing. This fact limits the maximum possible length of the closing spring. The limited space finally brings with it the disadvantage that these closing springs can no longer sufficiently absorb an increase in the load change on the closing springs.

  • the present invention is based on the idea to absorb an increased load change of the closing springs by as long as possible, maximum springs of a closing spring.

Abstract

La présente invention concerne un système d'arme (10). Ledit système d'arme comporte un canon (2) et un élément de fermeture (7) guidé dans un boîtier (3) de l'arme. Ledit élément de fermeture est déplacé par au moins un piston à gaz (4) et par un dispositif à ressort de fermeture (13) qui coopère avec le piston à gaz (4) et qui est relié structurellement à celui-ci. Selon l'invention, des passages de gaz (14) sont ménagés entre le canon (2) et le piston à gaz (4). Pour permettre aux ressorts de fermeture (5) de mieux absorber les efforts alternés, le piston à gaz (4) est monté sur ou dans le canon (2) et le dispositif à ressort de fermeture (13) est intégré dans le boîtier (1) de l'arme.
