Abstract
An air gun with a quick-release pneumatically operated gas valve that includes a piston positioned in a cylinder with one closed end so that the piston may seat against a gas outlet to close the gas valve. A control reservoir filled with gas to a control pressure is formed in the cylinder between the piston and the closed end of the cylinder so that the control pressure acts against the piston to close the gas valve. Opening a trigger valve allows the gas in the control reservoir to escape through an exhaust port, resulting in the gas valve being rapidly opened.
Claims20
A quick-release valve air gun for shooting a projectile, comprising:
- a barrel with a muzzle end and a breech end;
- a primary gas reservoir body of a gas valve configured with a primary gas outlet in gaseous communication with the breech end of the barrel;
- a piston with an outer end configured to slide into closed state providing the gas valve with an airtight seal, wherein a control reservoir is formed behind the piston receptacle adjacent an inner end of the piston;
- and
- trigger means for releasing control chamber gas from the control reservoir causing the piston to slide away from the primary gas outlet to an open state;
- wherein the piston sliding away from the primary gas outlet to the open state releases a sufficient amount of high pressure gas from the primary gas reservoir body into the breech end of the barrel to drive the projectile down the barrel out the muzzle end.
The quick-release valve air gun of claim 9, wherein the trigger means is a trigger valve with a plunger for operating the trigger valve.
A method of configuring a quick-release valve air gun to shoot a projectile, the method comprising:
- providing a barrel with a muzzle end and a breech end;
- providing a primary gas reservoir body of a gas valve, the primary gas reservoir body being having primary gas outlet that opens into the breech end of the barrel;
- mounting a piston receptacle within the gas valve to be in gaseous communication with the primary gas reservoir body;
- configuring a piston with an inner end configured to slide into the piston receptacle and with an outer end that provides the gas valve with an airtight seal in a closed state closing gaseous communication between the primary gas reservoir body and the breech end of the barrel, wherein a control reservoir is formed within the piston receptacle between an inner end of the piston and inner walls of the piston receptacle;
- and
- providing a trigger means for releasing control chamber gas from the control reservoir causing the piston to slide away from the primary gas outlet to an open state;
- wherein the piston sliding away from the primary gas outlet to the open state releases a sufficient amount of high pressure gas from the primary gas reservoir body into the breech end of the barrel to drive the projectile down the barrel out the muzzle end.
