Abstract:
1. A paintgun with pneumatic feeding and discharging process comprising: a) a trigger assembly used to actuate the firing element of paintballs; b) a barrel assembly fitted above the trigger assembly, a bore being provided at the front end thereof, a paintball-feeding tube being disposed above the bore; and c) a pneumatic delivery mechanism installed within the barrel assembly, including; whereby the stopper is used to control the opening or closing of air flow channel, thereby leading to a pressure difference between the front and rear air pressure chambers of the flow-guiding piston, and the delivery tube is shifted forward by means that a small amount of air flow is fed into the minor air channel so as to push a paintball a little forward; thereafter, the paintball is discharged by means of thrust of air flow into the major air channel.
