摘要： The present invention provides a pressure differential bullet advancing structure for advancing BB bullets, which includes an expansion device (1), a collar device (2) that is slidably received in the expansion device (1), and a pneumatic module (3) arranged at one side of the expansion device (1). The expansion device (1) includes a guide bar (12) that is received in the collar device (2). The guide bar (12) has a circumferential wall forming an air inlet opening (121) that is extended in a direction away from the pneumatic module (3) and is selectively shielded by the collar device (2). The pneumatic device generates high-pressure air that flows through the expansion device (1) to move the collar device (2) for advancing the BB bullet. When the collar device (2) is moved to such an extent that the air inlet opening (121) is exposed, the high-pressure air flows therethrough to shoot out the BB bullet.

摘要： An automatic air sports gun capable of reducing the size of a piston block and effectively utilizing the gas pressure of compressed gas, wherein a switching valve (34) and a stop valve (32) are positioned under a cylinder block (30), a closed part (35) of the switching valve (34) is exposed to the inside of a switching valve air chamber (21), and the switching valve (34) is set so that only a rod part (36) is positioned inside the switching valve air chamber (21) and, when the compressed gas is fed toward a shooting bullet vent hole (19) through the inside of the switching valve air chamber (21), the closed part (35) opens the shooting bullet feed port (22) so that the flow of the compressed gas to the shooting bullet feed port is not obstructed and, when the compressed gas is fed to a blow back vent hole (20), the closed part (35) closes a blow back air feed port (23) so that only the rod (36) of the switching valve (34) obstructs the supply of the compressed gas inside the switch valve air chamber (21).

摘要： A paintball marker is provided including a body (14), a bolt (16) and an actuator (18). The body (14) defines a breech having a paintball inlet (22). The bolt (16) is slideable within the breech between an open position wherein the bolt permits the entry of a paintball through the paintball inlet into the breech, and a closed position wherein the bolt prevents the entry of a paintball through the paintball inlet into the breech. The actuator (18) is operatively connected to the bolt (16). The actuator (18) is adapted to apply an opening force to move the bolt towards the open position and a closing force to move the bolt towards the closed position. The closing force is below a selected value.

摘要： A compressed gas powered gun having a valve assembly (40) for regulating the pressure from shot to shot, a trigger assembly (36) which alters the mode of operation of the gun and a bolt (38) for providing a recoil action and for releasing the gas from the valve assembly (40). The valve assembly (40) provides sufficient pressure to expel a projectile and to re-set the bolt (38) into its firing position. The trigger assembly is formed from a trigger (26), a four-position selector switch (46), and a sear (74). The gun uses an operation rod (118), which is integrally connected to the bolt (38) to advance the gun's magazine.

摘要： It is possible for an automatic sport air gun to make a piston block become a small size and to effectively use a gas pressure of a compressed gas.
In the automatic air sport gun, a change valve 34 and a open-close valve 30 is positioned below a cylinder block 30. A closing portion of the change valve 34 is exposes in a change valve gas chamber 21. The change valve 34 is located so that only a rod portion 36 is positioned in the change valve gas chamber 21. When the compressed gas is supplied to a side of a bullet discharge ventilating opening 19 through the change valve gas chamber 21, the closing portion 35 makes a bullet discharge air-supply opening 22 become an opening state so as to allow the compressed gas to flow to the bullet discharge air-supply opening 22. When the compressed gas is supplied to a blow-back ventilating opening 20, the closing portion 35 makes a blow-back air-supply opening 23 become the opening state. At that time, only the rod 34 of the change valve 34 prevents supply of the compressed gas in the change valve gas chamber 21.

摘要： The invention relates to a compressed-gas firearm (1), in particular a multiple-shot pistol, characterized by a novel valve system (39) for the pulsed release of compressed gas when firing a shot. The valve system (39) comprises two separately acting sealing devices, which are located opposite each other in the frontal end area of the valve chamber (19). The sealing devices both comprise one sealing ring each (22, 23), whose shape and position, in cooperation with the axially movable valve push rod (15), have a self-cleaning effect.

摘要： A bolt (141) having an opening formed therethrough is slidably located in the bore (52) of the gun. The bolt is held in a rear position by a sear (339) with the bolt opening closed by a valve (121) which extends into the bolt opening and engages a rear facing bolt seat (231). A passageway (125, 127) extends into the bolt opening by way of a valve for allowing pressurized gas to flow into the bolt opening. A trigger mechanism (309) releases the bolt for allowing the bolt to be moved forward for allowing the valve and seat to separate for allowing the gas to flow through the bolt opening for forcing a ball (59) from the rear end of the barrel out of the gun. A cock valve (421) located in a cock valve chamber (381) releases gas to force the bolt back to the rearward position.
