Gas-powered gun
A gas-powered gun for discharge of projectiles, comprising a pressure chamber for holding compressed gas, a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in a barrel, and a plenum chamber in fluid connection with the pressure chamber. The plenum chamber is formed coaxially around a rear portion of the barrel.
1. A gas-powered gun for discharge of projectiles, comprising:
a barrel;
a pressure chamber for holding compressed gas;
a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in the barrel;
a plenum chamber in fluid connection with the pressure chamber; and
a pressure regulator providing a controlled pressure in the pressure chamber and the plenum chamber,
wherein the plenum chamber is formed around at least a rear portion of said barrel and is formed by a sleeve surrounding the barrel, said sleeve being sealed in a front end by a front sealing and in a rear end by a rear sealing, said rear sealing formed with a passage providing a fluid connection between the plenum chamber and the pressure chamber.
2. The gas-powered gun according to claim 1 , wherein the pressure chamber is in fluid connection with a source of pressurized air via the pressure regulator.
3. The gas-powered gun according to claim 2 , wherein the source of pressurized air is a bottle containing compressed air which has been fitted to the gas-powered gun.
4. The gas-powered gun according to claim 1 , wherein the valve is an open-close valve that connects the pressure chamber to a space behind a firing position in the barrel.
5. The gas-powered gun according to claim 4 , further comprising:
a trigger which is mechanically connected to a spring-loaded hammer that is configured to operate the open-close valve.
6. The gas-powered gun according to claim 5 ,
wherein the hammer is biased towards the open-close valve by a biasing spring and is held against a force of the biasing spring by a catch, and
wherein the trigger is operable to release the catch.
7. The gas-powered gun according to claim 1 , further comprising:
a feeder pin arranged in a housing behind the barrel, said feeder pin being operable between (i) a rearwards position, in which the feeder pin allows a bullet to be inserted in a space in front of the feeder pin and (ii) a forwards position in which the feeder pin pushes the bullet into a firing position.
8. A gas-powered gun for discharge of projectiles, comprising:
a barrel;
a pressure chamber;
a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in the barrel;
a plenum chamber in fluid connection with the pressure chamber;
a pressure regulator providing a controlled pressure in the pressure chamber and the plenum chamber, and
a passage between the pressure chamber and the plenum chamber,
wherein the plenum chamber is an extension of the pressure chamber, and
wherein the plenum chamber is formed by a sleeve surrounding the barrel, said sleeve being sealed in a front end by a front sealing and in a rear end by a rear sealing, said rear sealing formed with a passage providing a fluid connection between the plenum chamber and the pressure chamber.
9. The gas-powered gun according to claim 8 , wherein the sleeve is arranged coaxially around the barrel.
10. The gas-powered gun according to claim 8 , further comprising:
a source of pressurized air, wherein said source of pressurized air is a bottle containing compressed air which has been fitted to the gas-powered gun.
11. The gas-powered gun according to claim 8 , wherein the valve is an open-close valve that connects the pressure chamber to a space immediately behind a firing position in the barrel.
12. The gas-powered gun according to claim 11 , further comprising:
a trigger mechanically connected to a spring-loaded hammer, said hammer being configured to operate the open-close valve.
13. The gas-powered gun according to claim 12 , wherein the spring-loaded hammer is biased towards the open-close valve by a biasing spring and is held against a force of the biasing spring by a catch, wherein the trigger is operable to release the catch.
14. The gas-powered gun according to claim 13 , further comprising:
a feeder pin arranged in a housing behind the barrel, said feeder pin being operable between (i) a rearward position, in which the feeder pin allows a bullet to be inserted in a space in front of the feeder pin, and (ii) a forward position in which the feeder pin pushes the bullet into the firing position.
15. A gas-powered gun for discharge of projectiles, comprising:
a barrel;
a pressure chamber for holding compressed gas;
a plenum chamber in fluid connection with the pressure chamber;
a pressure regulator providing a controlled pressure in the pressure chamber and the plenum chamber, and
a valve configured to release compressed gas from both the pressure chamber and the plenum chamber to thereby discharge a projectile provided in the barrel,
wherein the plenum chamber is formed by a sleeve surrounding the barrel, said sleeve being sealed in a front end by a front sealing and in a rear end by a rear sealing, said rear sealing formed with a passage providing a fluid connection between the plenum chamber and the pressure chamber.
16. The gas-powered gun according to claim 15 , wherein the sleeve is arranged coaxially around the barrel.
17. The gas-powered gun according to claim 15 , further comprising:
a source of pressurized air, wherein said source of pressurized air is a bottle containing compressed air which has been fitted to the gas-powered gun.
18. The gas-powered gun according to claim 15 , wherein the valve is an open-close valve that connects the pressure chamber to a space immediately behind a firing position in the barrel.
19. The gas-powered gun according to claim 18 , further comprising:
a trigger mechanically connected to a spring-loaded hammer, said hammer being configured to operate the open-close valve, wherein the spring-loaded hammer is biased towards the open-close valve by a biasing spring and is held against a force of the biasing spring by a catch, wherein the trigger is operable to release the catch.
20. The gas-powered gun according to claim 19 , further comprising:
a feeder pin arranged in a housing behind the barrel, said feeder pin being operable between (i) a rearward position, in which the feeder pin allows a bullet to be inserted in a space in front of the feeder pin, and (ii) a forward position in which the feeder pin pushes the bullet into the firing position.
