Abstract
A compressed gas powered gun includes an arrangement that meters the amount of air flow exiting through an outlet port of the gun that tends to restrict the velocity of the exiting air to be less than the speed of sound during normal operation. In addition, the exit velocity of the projectile is less sensitive to pressure variations and may be more closely controlled so that shot to shot consistency of the gun is increased. The firing rate of the gun can also be modified.
