US12352522 - Air gun with mixed gas charge

An air gun includes a first reservoir storing a first compressed gas, e.g., compressed air, and a second reservoir storing a second compressed gas different from the first compressed gas, e.g., helium. A mixed gas system mixes a supply of the first compressed gas and a supply of the second compressed gas as a gaseous mixture. A firing valve is selectively actuated to release the gaseous mixture to a barrel of the air gun, to fire the air gun.

The patent describes an air gun that utilizes a dual-reservoir system to store and mix two different compressed gases, enabling the release of a gaseous mixture to propel projectiles. This innovative design allows for enhanced performance by combining the properties of different gases during firing.

Claim 1

  1. An air gun comprising: a housing; a barrel extending from the housing; a first reservoir coupled to the housing and containing a first compressed gas; a second reservoir coupled to the housing and containing a second compressed gas different from the first compressed gas; and a fluid transfer system configured to perform operations comprising: receiving a first supply of the first compressed gas from the first reservoir; receiving a second supply of the second compressed gas from the second reservoir; retaining a gaseous mixture including the first supply of the first compressed gas and the second supply of the second compressed gas; and transferring, in response to firing of the air gun, the gaseous mixture including the first supply of the first compressed gas and the second supply of the second compressed gas through the barrel to launch a projectile. a housing; a barrel extending from the housing; a first reservoir coupled to the housing and containing a first compressed gas; a second reservoir coupled to the housing and containing a second compressed gas different from the first compressed gas; and a fluid transfer system configured to perform operations comprising: receiving a first supply of the first compressed gas from the first reservoir; receiving a second supply of the second compressed gas from the second reservoir; retaining a gaseous mixture including the first supply of the first compressed gas and the second supply of the second compressed gas; and transferring, in response to firing of the air gun, the gaseous mixture including the first supply of the first compressed gas and the second supply of the second compressed gas through the barrel to launch a projectile. receiving a first supply of the first compressed gas from the first reservoir; receiving a second supply of the second compressed gas from the second reservoir; retaining a gaseous mixture including the first supply of the first compressed gas and the second supply of the second compressed gas; and transferring, in response to firing of the air gun, the gaseous mixture including the first supply of the first compressed gas and the second supply of the second compressed gas through the barrel to launch a projectile.
