Abstract

L'invention concerne un dispositif d'éjection pour une cartouche présentant deux chambres (1, 2), placées de manière concentrique l'une par rapport à l'autre, et un piston (4, 5) pour chaque chambre (1, 2). Ce dispositif d'éjection présente des poussoirs d'éjection qui peuvent coulisser en direction de l'ouverture de cartouche (3). Ces poussoirs d'éjection sont guidés à travers un capuchon (6) pouvant être bloqué dans le sens axial avec la cartouche. Les poussoirs d'éjection pour le piston annulaire (5) sont raccordés entre eux au niveau de leurs extrémités extérieures par l'intermédiaire d'un élément de tête (11) sur lequel prend appui une broche filetée (9) s'étendant à travers un orifice fileté (8) du capuchon (6) et servant de poussoir d'éjection pour le piston central (4).
