Pneumatic paintball gun
DCFirst Claim
1. A pneumatic paintball gun, comprising:
- a bolt slidably mounted in a cylinder, said bolt having one or more first surface areas and one or more second surface areas,said bolt further comprising a bolt port configured to communicate compressed gas to a forward end of the bolt for launching a paintball;
a sealing member positioned in a fixed relationship with respect to the cylinder and arranged in communication with an outer surface of the bolt, wherein the sealing member is configured to prevent compressed gas from a compressed gas storage area from entering the bolt port when the bolt is in an open position and to permit compressed gas to be released into the bolt port when the bolt is in a closed position;
a supply port arranged to supply-compressed gas to the compressed gas storage area, wherein compressed gas from the compressed gas storage area supplies a forward force on one or more of the second surface areas of the bolt to urge the bolt towards the closed position when the compressed gas storage area is pressurized;
a solenoid valve arranged to supply compressed gas to one or more of the first surface areas, wherein compressed gas acting on the one or more first surface areas provides a rearward force greater than the forward force acting on the one or more second surface areas to hold the bolt in an open position; and
wherein the solenoid valve is configured to selectively vent compressed gas from one or more of the first surface areas to allow the bolt to move forward using the forward force supplied to the bolt.

Abstract
A pneumatic paintball gun preferably includes a body and a grip. The body preferably holds a pneumatic housing that contains the primary operating components of the paintball gun. The pneumatic housing preferably includes a pneumatic piston and cylinder assembly. The pneumatic piston is preferably coupled to a bolt for controlling movement of the bolt based on the supply and venting of compressed gas from the cylinder. Most preferably, a normally-open three way solenoid valve supplies compressed gas to a forward surface area of the piston to hold the bolt in an open position. In the open position, a paintball is permitted to load into a breech area of the paintball gun. In response to a trigger pull, the three-way solenoid valve is preferably configured to vent compressed gas away from the forward piston surface area. Pressure supplied to a rearward piston surface area preferably causes the bolt to close, moving the paintball into a barrel. The bolt is also preferably configured to operate as part of the firing valve, such that closing the bolt causes compressed gas to be released into contact with the paintball arranged in the barrel to launch it from the paintball gun. A paintball detection system can also be provided having a circuit board configured to fit in a recess formed in a breech section of the pneumatic housing.

13. A pneumatic paintball gun comprising:
-
a pneumatic assembly comprising a bolt and a firing mechanism arranged in a single longitudinal bore of the paintball gun; said bolt comprising one or more first surface areas and one or more second surface areas, said bolt further providing the firing mechanism of the paintball gun; a compressed gas storage area that supplies compressed gas to one or more of the second surface areas to provide a forward force on the bolt when the compressed gas storage area is pressurized; and a solenoid valve configured to selectively supply compressed gas to one or more of the first surface areas to provide a rearward force on the bolt that is greater than the forward force. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A pneumatic paintball gun, comprising:
-
a bolt and a firing mechanism arranged in a single longitudinal bore of the paintball gun; a compressed gas storage area supplying compressed gas to the bolt when the compressed gas storage area is pressurized to provide a forward force on the bolt; and a solenoid valve that selectively supplies compressed gas to the bolt to provide a rearward force on the bolt sufficient to overcome the forward force on the bolt.
