Abstract: An improved paintball gun uses a low-pressure pneumatic sear to hold the firing valve closed against the high pressure gas occupying the other side of the valve. In this manner, only one operation is required between depressing the trigger and the firing of the paintball gun because a double-acting cylinder is not required as an interface between the trigger depression and actuation of the valve. The paintball gun is also substantially faster than existing electro-pneumatic paintball guns because it uses a blow forward bolt, in which higher-pressure gas is held directly behind the bolt and has only one direction to travel during the firing of the paintball gun.

Abstract: A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position; this increases efficiency in the marker because only the required air is used to fire the paintball. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without the use of tools, and gives the user a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

Abstract: The paintball marker has a specially curved discharge port and port within a bolt within the breech for a compressed gas powered gun for the firing of projectiles. The marker has an adjustable volume high pressure chamber that releases compressed gas to fire a paintball.

Abstract: The present invention is a specially curved discharge port and port within a bolt within the breech for a compressed gas powered gun for the firing of projectiles. The invented gun has many improvements over the prior art including the use of improved gas pressure routing allowing for operation at lower pressures with no decrease in firing rate, efficiency, trajectory, or range. The structure of the present invention provides for embodiments which include the use of specific maximum angles within the gas passage from a compressed gas storage chamber and a portion of the breech through which the gas is routed as it expands to launch a projectile from the gun.
