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

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.
