Abstract: A bullet feed portion reciprocates and is positioned in a firing position where a bullet housing chamber is opposed to a bullet feed port, and in a non-firing position where the bullet feed port is closed. A gas flow path guides compressed gas to the bullet feed port in an inner barrel. A valve is biased to close the gas flow path. A firing action mechanism has a movable body that can be freely reciprocated along the inner barrel. The firing action mechanism moves the bullet feed portion to a firing position and moves the valve to a non-biasing direction. A power transmission unit transforms motor force into the locomotion of a movable body. When trigger is pulled, the motor moves the movable body toward the bullet feed port to feed a bullet into the bullet feed portion, and actuate the firing action mechanism.

Abstract: A cartridge-based air gun that fires a BB bullet or a resin bullet inside a cartridge using compressed gas, includes an engaging structure of an extractor that enables blowback and the automatic ejection of the cartridge. An extractor, which engages with a rim that is formed at the rear end of a cartridge loaded in a chamber, is pivotally provided on a side portion of a cylinder so as to be rotatable. A claw portion formed at the tip of the extractor engages with the rim of the cartridge by the urging force of a spring provided between the extractor and the cylinder. A slide moves rearward while the cartridge is held inside the chamber. As the cylinder moves rearward with the stopping of the supply of compressed gas from a gas reservoir, the cartridge comes into contact with an ejector, is released from the engagement by the extractor, and is ejected from the chamber.

Abstract: A pneumatic paintball marker has, for example, a sleeve that controls the passage of air through the longitudinal barrel or opening within the marker. By sequentially filling separate chambers defined within the opening and the sleeve, the sleeve is able to translate axially through the opening in a sequential manner. When the sleeve is in a forward position, air is caused to be released through the barrel, propelling the paintball. A sear member engages the sleeve and prevents it from inadvertently moving to a forward position. Air filling the chambers returns the sleeve to the loading position.

When connected to a conventional paintball marker 10, the pressure vessel 12 magnetically shows the indicated location of the magnetic float assembly 42, thereby showing the amount of liquid phase CO2 39 remaining within the pressure vessel 12. This remaining amount of liquid phase CO2 39 can be correlated to an approximate number of additional paintball rounds that can be shot before the CO2 is depleted.

Abstract: An air gun includes a retainer pivotably connected inside the air gun and having a bullet abutment part that pivots into and out of a bullet-receiving chamber. The retainer is resiliently biased to pivot in a forward direction so that the bullet abutment part is urged into the bullet-receiving chamber. In a trigger rest position, a hollow inner barrel prevents a bullet and the bullet abutment part from entering into the bullet-receiving chamber. Upon pulling the trigger, the inner barrel moves in a forward direction to permit the bullet and the bullet abutment part to enter the bullet-receiving chamber where the bullet abutment part contacts and retains the bullet therein. Upon pulling the trigger further, the inner barrel moves in a rearward direction to capture the bullet therein while causing the retainer to pivot in the rearward direction to thereby move the bullet abutment part out of the bullet-receiving chamber.

Abstract: This specification discloses a structure of the paintball gun. It comprises a body, a pressuring set, and a triggering set. The body has an axial passage whose front end forms a paintball outlet. The triggering set and the pressuring set are disposed in sequence inside the passage. The triggering set has a bushing, a guide pillar, and a bolt. The bushing is fixed inside the passage. The bolt is mounted on the guide pillar and disposed together inside the bushing.

Abstract: A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without the use of tools, and gives the user a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.
