Adjustable volume chamber and low pressure regulator for a compressed gas gun

Abstract

The paintball marker has 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 marker has an adjustable volume high pressure chamber that releases compressed gas to fire a paintball.

1 . A paintball marker comprising: 
 a source of compressed gas that supplies a high pressure storage chamber;    a low pressure regulator that is supplied with high pressure gas from the high pressure storage chamber;    wherein the low pressure regulator has a longitudinal axis perpendicular to a longitudinal axis of the high pressure storage chamber.    
     
     
         2 . The paintball marker of  claim 1 , wherein the low pressure regulator is located adjacent to a trigger guard.  
     
     
         3 . The paintball marker of  claim 1 , wherein the high pressure storage chamber has an adjustable volume.  
     
     
         4 . The paintball marker of  claim 1 , wherein the high pressure storage chamber has an adjustable volume chamber attached thereto, comprising 
 an outer main body that defines a hollow interior chamber, which is adjustable in size by an adjustment screw.    
     
     
         5 . The paintball marker of  claim 4 , wherein the adjustable volume chamber further comprises: 
 a piston attached to the adjustment screw, and having a seal thereon, said piston defining a boundary of the hollow interior chamber.    
     
     
         6 . A paintball marker comprising: 
 a source of compressed gas that supplies a high pressure storage chamber having an adjustable volume chamber attached thereto, said adjustable volume chamber comprising an outer main body that defines a hollow interior chamber that is in communication with the high pressure storage chamber, said hollow interior chamber being adjustable in size by an adjustment screw, said high pressure chamber supplying a source of compressed gas that is released to fire a paintball from the marker.    
     
     
         7 . The paintball marker of  claim 6 , wherein the adjustable volume chamber further comprises a piston attached to the adjustment screw, and having a seal thereon, said piston defining a boundary of the hollow interior chamber.  
     
     
         8 . The paintball marker of  claim 7 , wherein the piston is attached to a terminal end of the adjustment screw.  
     
     
         9 . The paintball marker of  claim 7 , wherein the piston comprises a groove with a seal therein, which acts to seal a portion the hollow interior chamber.  
     
     
         10 . The paintball marker of  claim 6 , wherein the adjustable volume chamber is removable from said marker.  
     
     
         11 . A paintball marker comprising: 
 a breech having a forward end and a rear end;    a bolt having a port therethrough contained within the breech, the bolt moveable within the breech between a rearward position to a forward position;    a chamber adjacent to the breech having a forward end and a rear end, the chamber containing a slider moveable between a rearward and a forward position, the slider connected to the bolt, a chamber input port providing communication between the chamber and a source of compressed gas at a first pressure, wherein the compressed gas at a first pressure passes through the chamber input port to move the slider toward the forward position;    a high pressure storage chamber that stores compressed gas at a second pressure, and upon actuation of a poppet valve by the slider in its forward position, releases said gas at a second pressure to drive a ball from the marker; and    a low pressure regulator that is supplied by gas from the high pressure storage chamber, and lowers said first pressure to a lower second pressure.    
     
     
         12 . The paintball marker of  claim 11 , further comprising an adjustable volume chamber having a hollow interior chamber in communication with the high pressure storage chamber, said hollow interior chamber allowing for expansion of the compressed gas at a first pressure, lowering said first pressure.  
     
     
         13 . The paintball marker of  claim 12 , wherein the hollow interior chamber's volume is adjusted by turning a screw.  
     
     
         14 . The paintball marker of  claim 13 , wherein the hollow interior chamber comprises a piston therein that moves in response to turning the adjustment screw, to contract of expand the hollow interior chamber's volume.
