  • Patent number: 8887708
    Abstract: An improved paintball marker with electro-pneumatic firing mechanism that employs two separate solenoid valves: a low pressure solenoid valve for bolt actuation and a high pressure solenoid valve for exhaust valve actuation to fire the paintball. The exhaust valve is completely independent of the bolt movement. This eliminates the need for a mechanical ram to strike the exhaust valve. Fewer moving parts and a smaller moving mass reduces recoil and improves reliability and overall operation of the marker. Moreover, the design is more modular and allows for easier disassembly and maintenance.
