Abstract
The proposed invention is a new bolt and gas release valve mechanism for a projectile launching device, such as a paintball marker, that uses significantly less gas per shot than prior art devices. The open gas chamber between the projectile, such as a paintball, and the gas release mechanism is eliminated thereby requiring much less gas to be used for each launch of a given projectile. Thus, only the launching gas to propel the projectile is needed and not the additional gas required to fill the chamber in the bolt directly behind the projectile. This enables desirably smaller gas supply tanks to be used during use to launch the same number of projectiles. Also, with the present invention, more projectiles can be launched using the same gas supply tank.
