Patent ID: 8573191

Claim:
A pneumatic paintball gun, comprising: a cylinder including a firing mechanism moveable from a first position to a second position, the cylinder having a compressed gas storage chamber configured to receive compressed gas and the compressed gas in the compressed gas storage chamber is configured to provide a forward force on the firing mechanism; the firing mechanism having an integral pneumatic piston extending substantially along central longitudinal axis of the firing mechanism, and an integral bolt including a forward bolt opening configured to communicate compressed gas to a forward end of the bolt for launching a paintball from the gun wherein the pneumatic piston has a diameter less than a diameter of the bolt; a seal configured to prevent compressed gas from communicating with the forward bolt opening when the bolt is in a first position and to permit compressed gas to flow through the forward bolt opening when the bolt is in a second position; a solenoid valve configured to regulate the supply of compressed gas to a forward surface area of the firing mechanism to hold the firing mechanism in an open position; wherein the solenoid valve is configured to vent compressed gas from the forward surface area to allow the firing mechanism to move to a second position under the force of the compressed gas from the compressed as storage chamber, and to allow the release of compressed gas from the compressed gas storage chamber through the forward bolt opening to fire the paintball gun.
