Abstract

L'invention a pour objet un dispositif d'obturation pour canon d'armes à feu permettant l'utilisation de munitions sans étui métallique. Le dispositif est constitué par une pièce mobile I placée devant la tête de culasse, cette pièce comporte dans sa partie avant un évidement conique 2 et un évidement arrière cylindrique 3, ces deux évidements sont réunis par un trou évent 5, la pression exercée par les gaz dans l'évidement arrière fait avancer la pièce mobile et l'appuie contre le tonnerre du canon ce qui assure son obturation. L'application de ce dispositif d'obturation convient au armes à feu de tout type et de toute puissance.
