Compressed gas gun
A compressed gas gun including a housing and a bolt movable within a passage in the housing. Movement of the bolt relative to the housing opens a flow path for firing a projectile.
1. A compressed gas gun, comprising:
a housing including a compressed gas receiving portion configured to receive compressed gas from a source of compressed gas;
a housing passage arranged within the housing;
a piston having a passage through at least a portion of the piston slidably arranged within the housing passage and moveable between a rearward position and a forward position relative to a seal, a surface of the piston in communication with the seal, the piston having an opening adjacent a forward portion of the piston, wherein movement of the piston relative to the housing from the rearward position to the forward position opens a flow path providing communication between the compressed gas receiving portion of the housing and the piston opening; and
a trigger-actuated valve configured to control the flow of compressed gas in communication with a forward facing surface of the piston.
2. The compressed gas gun of claim 1 , wherein a stationary sealing member is provided in the housing configured to prevent the piston opening from receiving compressed gas when the piston is in a rearward position and to allow the piston opening to receive compressed gas when the piston is in a forward position.
3. The compressed gas gun of claim 1 , wherein the piston has an increased outer diameter portion.
4. The compressed gas gun of claim 1 , wherein a stationary housing extension portion extends from a rear portion of the passage and is received within the passage adjacent a rear portion of the piston.
5. The compressed gas-powered gun of claim 4 , wherein the housing extension further comprises at least one opening, the opening providing communication between the compressed gas receiving portion and the passage.
6. The compressed gas-powered gun of claim 1 , wherein the valve is an electro-magnetic valve.
7. The compressed gas-powered gun of claim 1 , further comprising a control circuit for controlling a firing operation of the gun.
8. The compressed gas-powered gun of claim 7 , wherein the control circuit comprises a pressure sensor.
9. The compressed gas-powered gun of claim 1 , wherein the housing includes a removable cap configured to permit removal of the holt piston.
10. A compressed gas gun, comprising:
a housing including an interior portion adapted to receive compressed gas from a source of compressed gas;
a bolt positioned in a portion of the interior portion having a flow passage and an interior and exterior, the bolt slideable in the housing between a rearward position and a forward position;
the bolt being adapted when in the rearward position to prevent compressed gas from entering the interior of the bolt, and when in the forward position the bolt being adapted to permit compressed gas to enter the interior of the bolt, wherein the bolt is slideable on a bolt guide, a stationary seal provided between the bolt guide and the bolt;
the bolt having at least a portion adapted to move from rearward the seal to forward the seal to open a flow path for firing a projectile when the bolt moves between its rearward position and its forward position.
11. The compressed gas gun of claim 10 , wherein the bolt has an increased outer diameter portion.
12. The compressed gas gun of claim 10 , wherein a portion of the bolt guide includes a hollow interior area.
13. The compressed gas-powered gun of claim 10 , wherein the valve is an electro-magnetic valve.
14. The compressed gas-powered gun of claim 10 , further comprising a control circuit for controlling a firing operation of the gun.
15. The compressed gas-powered gun of claim 10 , wherein the control circuit comprises a pressure sensor.
16. The compressed gas-powered gun of claim 10 , wherein the housing includes a removable cap configured to permit removal of the bolt.
