| The present invention is revolver louver which redirects the hot propellant gases which leak from the barrel-cylinder gap away from the user. The louver provides at least one directional passages which control the flow of propulsion gases after firing the revolver. Numerous embodiments are disclosed including some having an expansion capability to further block gas passage and one embodiment which is an extension of the revolver frame itself. One embodiment further comprises an expansion groove to further block the passage of propulsion gases. As such, the present invention's general purpose is to provide a new and improved revolver that is more compact and safer for the user than a conventional revolver. | ||||||

| The invention relates to a firing apparatus for firing cartridges (1), in particular rifle cartridges, comprising an ammunition magazine (2) for receiving the cartridges (1) and a firing barrel (5) in front of the ammunition magazine (2) in the firing direction. In order to allow the pressure difference in the firing barrel (5) to be easily adapted to the requirements both in the high-pressure region, i.e. in front of the ammunition magazine (2), as well as in the low-pressure region, i.e. in front of the high-pressure region in the firing direction, the invention is characterized by a high-pressure chamber (3), which surrounds the rear end of the firing barrel (5) when seen in the firing direction; a low-pressure chamber (4) which is arranged in front of the high-pressure chamber (3) when seen in the firing direction and which surrounds the firing barrel (5); high-pressure bores (5a) in the firing barrel (5) in the region of the high-pressure chamber (3), said bores connecting the interior of the firing barrel (5) to the high-pressure chamber (3); and rear and front low-pressure bores (5b), when seen in the firing direction, in the firing barrel (5) in the region of the low-pressure chamber (4), said bores connecting the interior of the firing barrel (5) to the low-pressure chamber (4). The firing apparatus also comprises a blow-out channel (6) which connects the high-pressure chamber (3) to the atmosphere and is equipped with an adjustable valve (7). | ||||||

| A recoil-actuated gun scavenger for a gun having a bore, a breech, a recoiling mass, and a non-recoiling mass. The scavenger may include a pneumatic cylinder and a piston translatable therein. A rod may be fixed to the piston. The cylinder and rod may be fixed to respective recoiling and non-recoiling masses, or vice versa. The cylinder may include intake and exhaust ports with check valves, on both sides of the piston. The exhaust ports may communicate with an accumulator. The accumulator may discharge compressed air to jets located at the open breech end of the gun. | ||||||

| A firearm having a receiver housing an action-cycling mechanism, a barrel having a muzzle opening on a distal end, a shroud coaxially surrounding at least a portion of the barrel, the shroud having a distal portion extending beyond the muzzle opening defining a shroud front region having a distal end portion, a proximal portion extending proximally from the muzzle opening defining an annular region between the barrel and shroud, a front wall disposed at the distal end portion of the shroud, the front wall having an opening to allow passage of a projectile fired from the gun barrel, a firewall disposed in the annular region of the proximal portion of the shroud, the firewall moveable relative to the gun barrel between a forward, at-rest position, and a rearward, compressed position, the firewall mechanically engaged with the action cycling mechanism, and heat-dissipating fins in the annular region extending longitudinally along, and radially outward from, the gun barrel to the shroud, the fins defining channels, the firewall disposed in at least one of the channels. Gases generated during a fire compress the firewall rearward to operate the cycling mechanism. | ||||||
