Abstract

L'invention concerne des armes à feu actionnées par les gaz produits lors de la mise à feu d'une cartouche, capables d'un fonctionnement au moins semi-automatique. L'invention se caractérise essentiellement par un dispositif permettant d'ajuster le passage des gaz entre l'âme du canon et le mécanisme d'actionnement et qui comprend un manchon 41 avec un épaulement annulaire 44 en contact avec la jupe 35 d'un piston annulaire 33, ce manchon pouvant être ajusté par rotation pour masquer plus ou moins des lumières de prélèvement des gaz dans le canon. Le dispositif de l'invention permet de façon simple d'ajuster la force exercée par les gaz sur le mécanisme d'actionnement de l'arme en fonction de la charge de la cartouche tirée, de façon à ce que cette force reste toujours égale.The invention relates to firearms actuated by the gases produced during the firing of a cartridge, capable of at least semi-automatic operation. The invention is essentially characterized by a device making it possible to adjust the passage of gases between the core of the barrel and the actuating mechanism and which comprises a sleeve 41 with an annular shoulder 44 in contact with the skirt 35 of a piston. annular 33, this sleeve being able to be adjusted by rotation in order to more or less mask the openings for taking off the gases in the barrel. The device of the invention makes it possible in a simple manner to adjust the force exerted by the gases on the actuating mechanism of the weapon as a function of the load of the cartridge fired, so that this force always remains equal.
