Abstract
An improved paintball marker bolt and bolt head uses a curved gas inlet ramp and geometrically designed outlet holes to provide pressurized gas flow with decreased turbulence and more uniform distribution over the paintball surface. The improvements in gas flow and pressure distribution are combined with other mechanical improvements related to drive transfer, friction reduction, and bolt assembly, resulting in a significantly improved marker bolt. Improvements are realized in increased gas flow efficiency, increased paintball velocity (by 30 feet per second or more), increased range, improved shot consistency (less than a 2½% variation in shot-to-shot paintball velocity), decreased jamming, and decreased premature paintball breakage.
Claims34
A paintball marker bolt, comprising:
- a substantially cylindrical body, having
- an external diameter,
- a body centerline defined by the external diameter,
- an external surface,
- a forward end and an aft end,
- an internal passageway contained within the body, and
- an inlet hole connecting the external surface to the internal passageway;
- a face, centered upon the forward end of the substantially cylindrical body,
- the face having a geometrical center and
- at least one exit hole connecting the face to the internal passageway;
- and
- a separately prefabricated ramp, situated inside the substantially cylindrical body, and having a flow-directing surface exposed to both the inlet hole and the internal passageway.
