Patent ID: 7111621

Claim:
A paintball marker gun comprising; a handle assembly; a gun body assembly interconnected to said handle assembly, said gun body comprising; a) a parallel chamber housing having a forward end and an aft end, said housing comprising; i) an elongate barrel for receiving and expelling paintballs, said barrel having a forward end and an aft end; and ii) an elongate bore having a forward end and an aft end wherein said barrel and bore are in gas flow communication; b) a slide cover, adapted to partially cover and slideably engage the chamber housing between forward and aft positions; and c) a biasing member interconnected between said chamber housing and said slide cover to provide a biasing force upon said slide cover to bias the slide cover to the forward position; a gas pressure source; a poppet valve positioned within the bore of the chamber housing in gas flow communication with the gas pressure source, said poppet valve having a compression switch for opening the valve and releasing high pressure gas into the bore and barrel of the chamber housing; a hammer and bolt assembly positioned within the chamber housing, said hammer and bolt assembly comprising; a) a generally cylindrical bolt positioned in the barrel of said chamber housing, said bolt interconnected to said slide cover, said bolt moveable between a forward and aft position; b) a hammer assembly positioned in the bore of said chamber housing, said hammer assembly comprising; i) a compression hammer movable between forward and aft positions, wherein in said forward position said compression hammer engages the compression switch of the poppet valve, and wherein said aft position, said hammer assembly is cocked; ii) a biasing member in mechanical communication with said compression hammer to provide a biasing force upon said compression hammer to bias the compression hammer to the forward position; and iii) a generally cylindrical hammer sleeve having a forward aperture and aft aperture, said hammer sleeve movable between forward and aft positions and interconnected to said bolt, said hammer sleeve having an internal bore sized to receive the compression hammer through said aft aperture, and said front aperture sized to permit passage of at least a portion of the compression hammer in its forward position to engage the compression switch of the poppet valve; and an actuator in mechanical communication with said compression hammer, for releaseably holding the compression hammer in a cocked configuration.
