Patent ID: 8113189

Claim:
A compressed gas gun comprising: a cylinder comprising a piston having a passage therethrough and a valve pin, wherein the piston is axially slidable from a rearward position to a forward position within the cylinder and movement of the piston also moves the valve pin, at least a portion of the valve pin positioned coaxially within the passage of the piston; a valve housing having a passage therethrough positioned within the cylinder, at least a portion of the valve housing coaxially receivable within the passage of the piston, at least a portion of the valve pin coaxially receivable within the passage of the valve housing, wherein movement of the piston and valve pin relative to the valve housing selectively controls the flow of compressed gas through the valve housing; compressed gas at a first pressure that biases the valve pin and piston toward the forward position; compressed gas at a second pressure that biases the valve pin and piston toward the rearward position, and overcomes a force exerted by the first pressure biasing the valve pin and piston toward the forward position; and a valve that, in response to a signal, decreases the second pressure enough to allow the compressed gas at the first pressure to move the valve pin and piston toward the forward position; and a gas governor positioned in the cylinder in a gas governor chamber, the gas governor positionable to selectively engage the valve pin to restrict movement of the valve pin toward the rearward position, the gas governor configured to selectively prevent compressed gas from the gas governor chamber from communicating with the piston.
