Patent

CA 2645848

A pneumatic launcher includes a number of chambers for holding a compressed gas and a valve for releasing the compressed gas into a firing chamber to fire a projectile. The firing valve may include a number of surfaces on which pressure acts to slide a sliding valve body between an open position and a closed position. The launcher may include a recess for preventing pressure from acting on one of those surfaces when the valve is in the closed position. A part of the sliding valve body may interact with adjacent parts to form a closed region ahead of the sliding valve body, in order to cushion motion of the sliding valve body. The launcher may have a breech and a breech pin shaped to create a desired gas flow within the firing chamber during firing. The breech may include a breech pin seal which seals between two faces oriented transverse to the axis of the launcher. The launcher barrel may have a number of ribs for improved stability and accuracy.
