Abstract:
1. A pneumatic launching assembly, comprising: a launching body; a bolt disposed within the launching body and being movable between a loading position, to receive a projectile, and a launching position, that moves a projectile into a launching position; the bolt including a front end with an aperture therethrough; the front end being in communication with a projectile; a gas release member slidably disposed inside the bolt providing a gas valve behind the projectile with a front gas chamber therebetween; the space between the bolt and the gas release member behind the gas valve defining a firing gas chamber; the front gas chamber being substantially smaller than the firing gas chamber; the gas release member including a front sealing member releasably enagageable with the front end of the bolt to releasably seal the aperture thereof; whereby the bolt is moveable forwardly together with the gas release member to position the projectile into a launching position where further travel of the bolt causes the gas release member to separate therefrom to release gas behind the projectile for launching thereof while avoiding wasteful filling of the front gas chamber behind the projectile.
