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.”
