Patent ID: 7490598

Claim:
A paintball marker comprising in combination: a high pressure air source; a body; said body including and supporting a barrel, a firing chamber, a paintball input and a main valve; said main valve adapted to allow high pressure air to pass from said high pressure air source to said firing chamber when open; a trigger; a ram assembly, said ram assembly including a housing with a bore therein, said bore having a piston therein and adapted to move within said bore, said piston adapted to move when said trigger is actuated, said ram assembly further including a shaft coupled to said piston, said shaft adapted to move when said piston moves, said shaft further adapted to contact said main valve and open said main valve when said piston moves and said ram assembly is located adjacent said main valve; said main valve having an entrance non-parallel with an outlet; said main valve including an air pathway extending between said entrance and said outlet; said air pathway including at least one curve to align said air pathway with both said entrance and said outlet; wherein said outlet of said main valve is in fluid communication with said firing chamber through a bolt, said bolt including a guide surface along at least one side of an air path between said outlet of said main valve and said firing chamber, said guide surface extending in substantially planar fashion for at least half of a distance between a bolt air inlet and a bolt air outlet; wherein said bolt air outlet is adjacent said firing chamber, said firing chamber and said barrel having a common centerline extending out of said marker; and wherein said bolt air outlet has a cross-sectional area perpendicular to a direction of air flow that has a greater portion below said centerline of said firing chamber than above said center line of said firing chamber with said airflow concentrated to strike a ball in said firing chamber primarily below a centerline of the ball.
