Pneumatic Single Pulse Driven Bolt and Valve Assembly

Abstract

Disclosed is a pneumatically operated, projectile impelling apparatus having a single pulse driven pneumatic bolt/valve assembly. The assembly is used in an action mechanism in operative communication with a trigger group and a gun barrel. A single gas pulse operated bolt/valve assembly in the action mechanism operates on the input of a single gas pressure flow signal pulse to complete a complete firing cycle of chambering and launching a loaded projectile and to load a next projectile. The gas pulse is provided by trigger actuated fast acting, high flow rate gas valve disposed between a constant gas pressure flow supply and the action mechanism.

1 . A pneumatically operated projectile impelling apparatus having a single pulse driven pneumatic bolt/valve assembly, the apparatus comprising: 
 an action mechanism in operative communication with a trigger group and a gun barrel;    a single gas pulse operated bolt/valve assembly disposed in the action mechanism and operable on the input of single gas pressure flow signal pulse to complete a complete firing cycle of chambering and launching a loaded projectile and to load a next projectile; 
 a constant gas pressure flow supply selectably in operative communication with the action mechanism;  
   a trigger actuated fast acting, high flow rate gas valve disposed between the constant gas pressure flow supply and the action mechanism, and a trigger disposed in the trigger group and selectably operable to actuate the gas valve.
