  • Patent number: 8505525
    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 tools, and provides a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

  • Patent number: 8156930
    Abstract: A cartridge box of a pneumatic toy gun includes an air lock system and a struck element disposed on the upper inside the case of the cartridge box, and further includes a control system having a pushing rod and a resisting rod, wherein a front end of the pushing rod extends into the bullet-out passage disposed inside the case. When there is no bullet in the bullet-out passage, a lateral end of the stripping rod resists upward against the front end of the pushing rod to make the back end of the resisting rod moving downward to resist against the resisting portion of the struck element, resulting that the struck element cannot push the air lock system forward. Thereby, when there is no bullet in the cartridge box, even if the trigger is pressed, the air lock system cannot moves to push the bolt. Hence, firing without bullet will be avoided and the effects of the simulate gun would be achieved.

  • Patent number: 8113189
    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 tools, and provides a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.
