Abstract

Dispositif réducteur de bruit comportant une chambre d'expansion des gaz (11) et une partie centrale (2) cylindrique communiquant en amont avec la chambre d'expansion et débouchant en aval sur l'extérieur, caractérisé en ce qu'il comporte des moyens de répartition et de ralentissement (3) du flux des gaz depuis la chambre d'expansion (11), lesdits moyens étant agencés autour de la partie centrale (2) en communiquant avec la chambre d'expansion (11) et débouchant sur l'extérieur, et étant destinés à dévier une partie des gaz de la chambre de combustion pour engendrer un flux principal circulant dans la partie centrale et au moins un flux secondaire circulant dans un volume distinct formé autour de la partie centrale. Le dispositif procure une réduction significative du bruit et une diminution du recul de l'arme.Noise reduction device comprising a gas expansion chamber (11) and a central cylindrical part (2) communicating upstream with the expansion chamber and opening downstream to the outside, characterized in that it comprises means for distributing and slowing down (3) the flow of gases from the expansion chamber (11), said means being arranged around the central part (2) communicating with the expansion chamber (11) and opening onto the exterior, and being intended to divert part of the gases from the combustion chamber to generate a main flow circulating in the central part and at least one secondary flow circulating in a separate volume formed around the central part. The device provides a significant reduction in noise and a decrease in the recoil of the weapon.
