ABSTRACT:
Disclosed is a paint ball gun having a passage for porting pressurized gas to a ball projectile, a primary gas chamber, and a primary valve for controllably flowing pressurized gas from the primary chamber to the passage. The improved gun has a secondary gas chamber, an aperture connecting the passage and the secondary chamber and a spool-type secondary valve closing the aperture when the primary valve is in the intermediate position. The secondary chamber and secondary valve prevent pressurized gas from flowing into the hammer chamber (for re-cocking) until the ball is well on its way out of the barrel. Higher, more consistent ball velocity results. The new gun, of modular construction, also has a novel arrangement for controlling release of the hammer and "catching" such hammer as it is driven into its re-cocked position.
