Abstract
A paintball marker has a firing mechanism with at least a bolt, spool poppet valve, and vent. The bolt is slidable within a firing chamber and has a channel therethrough, The spool poppet valve has a large cross section portion and a smaller cross section portion, the larger cross section portion providing a seal against the bolt's channel. The smaller cross sectional portion has an O-ring that separates a channel, in which the spool poppet valve is slidably movable, into a front portion and a rear portion. Compressed gas enters the spool poppet valve's channel, in both the spool poppet valve's separated front and rear portions, and pushes the spool poppet valve towards the bolt, which in turn moves with the spool poppet valve. Finally, a vent through which the spool poppet valve channel's rear portion can vent to atmosphere, and upon such venting, the compressed gas in the spool poppet valve channel's front chamber drives the spool poppet valve away from the bolt, breaking the seal between the spool poppet valve and the bolt's channel, and compressed gas in the spool poppet valve channel's front portion and compressed gas in the firing chamber exits through the bolt's channel to drive a paintball from the marker.
