Patent ID: 7461646

Claim:
A bolt assembly for a paintball gun comprising a compressed gas storage chamber, said bolt assembly comprising: a valve stem comprising a gas supply passageway arranged longitudinally through the valve stem and a port communicating between the passageway and an exterior of the valve stem for supplying compressed gas to a compressed gas storage chamber arranged in the paintball gun; a bolt slidably mounted on the valve stem and comprising one or more bolt ports configured to communicate compressed gas from the compressed gas storage chamber to a forward end of the bolt for launching a paintball when the bolt is arranged in a second position; a sealing member arranged in communication with a surface of the bolt, wherein the sealing member is configured to prevent compressed gas in the compressed gas storage chamber from entering a forward bolt chamber when the bolt is in a first position and to permit compressed gas to enter the forward bolt chamber through the bolt ports when the bolt is in a second position; and a flow control member slidably arranged on an external surface of the valve stem and configured to slide between a first position and a second position to permit a flow of compressed gas from the valve stem port into the compressed gas storage chamber when the flow control member is in the first position and to occlude the valve stem port to cut off or restrict the flow of compressed gas from the valve stem port into the compressed gas storage chamber when the flow control member is in the second position.
