Abstract

The invention discloses an automatic firearm, suited to shoot shell-less and powderless cartridges, and wherein the thrust of the projectile (18) through the rifled barrel (2, 302) is obtained by the blast of an air/combustible mixture, under super critical conditions, within an explosion chamber (7). According to a preferred embodiment of the invention, the explosion chamber (7) receives heated and compressed air and combustible under such conditions as to cause the blast with or without the lighting of a spark in the interior of said explosion chamber. According to another embodiment of the invention, the super critical conditions of the air/combustible mixture are created within an explosion chamber, having a volume which varies according to the stroke of a sliding piston within a cylindrical body. When the volume of the explosion chamber reaches the minimum, the mixture explodes.
