Discharge port and breech for compressed gas gun

Abstract

The present invention is a specially curved discharge port and port within a bolt within the breech for a compressed gas powered gun for the firing of projectiles. The invented gun has many improvements over the prior art including the use of improved gas pressure routing allowing for operation at lower pressures with no decrease in firing rate, efficiency, trajectory, or range. The structure of the present invention provides for embodiments which include the use of specific maximum angles within the gas passage from a compressed gas storage chamber and a portion of the breech through which the gas is routed as it expands to launch a projectile from the gun.

I claim:  
     
         1 . In a compressed gas gun, the improvement comprising: 
 a gas passage conduit from a compressed gas storage chamber into a barrel for launching a projectile from said gas gun;    the conduit comprising a valved discharge port from said compressed gas storage chamber, said discharge port connected to a port within a bolt within a breech of said gas gun, said breech connected to the barrel of said gas gun; and,    all angled surfaces within said gas passage conduit forming a maximum angle of about 23 degrees ±5 degrees.    
     
     
         2 . The compressed gas gun of  claim 1  wherein the gun is electronically controlled.  
     
     
         3 . The compressed gas gun of  claim 1  wherein the gun has a high pressure circuit and a low pressure circuit.
