Abstract: Improvements in a more efficient use of air in a projectile launcher is disclosed. The launcher uses a two-stage air gun fire and reset to have a more efficient compressed gas usage because the gas is not wasted by performing simultaneous actions, instead, the motion dedicates a portion of the motion to firing only then transitions a “port” to close and redirect the gasses to “re-cocking” without wasted gasses going out the firing bolt. The air is redirected through a moving port or gate to allow the launcher to continue to perform and “cycle” to the point where there is low pressure in the supply tank. This prevents chopping or shredding of paintballs because the feed port of the projectiles only partially opens. The improvement allows the launcher to reliably feed and fire projectiles down to the point where it is obvious that the tank requires changing.

Abstract: A innovative sliding valve used in paintball gun or other compressed gas propelled firearm, wherein a portion of the valve body where air is exhausted is reduced in size to allow pressurized air to exhaust more quietly around the valve body by feeding into the air exhaust apertures formed on an extended wall of valve body.

Further, because the exhaust O-ring is contained with apertures and seals against the escaping air, with the resulting compression of the O-ring away from the sealing surface, the O-ring is held in place, and cutting and wear of the O-ring is substantially reduced.
