Abstract: A paint ball gun includes a barrel connected with a handle and a drop hole and an aperture are defined through a wall of the barrel. Paint balls can be supplied into the barrel via the drop hole. A linear motor is located in the barrel and drives a retractable driving rod which is connected to a push unit located in the barrel. An inlet is defined through a wall of the push unit and the inlet is moved with the push unit between a first position and a second position, the inlet is moved to the first position where the aperture is sealed and the paint ball enters the barrel. When the inlet is moved to the second position, the inlet is in communication with the aperture so that the paint ball is pushed by pressurized air introduced into the barrel via the aperture and the inlet.

Abstract: A shooting mechanism of a paint ball gun includes a valve located in the air tube of the gun and the valve is composed of a first member and a second member. A piston rod movably extends through the valve. The first member includes a shoulder extends radially and inward from an inner periphery of the first member. An aperture is defined in communication between the shoot tube located above the air tube and the first member. A piston head is connected to an end of the piston rod and removably seals the space, the other end of the piston rod is hit the strike rod. A flange extends radially outward from the piston rod and located between the shoulder and an inner end of the second member. The flange can be stopped by the shoulder of the first member when the piston rod is hit by the strike rod.

Abstract: A valve for a paint ball gun includes a case and a movable rod is movably received in the case. The movable rod has a first stop, a second stop and a third sop extending radially therefrom. A first chamber and a second chamber are respectively defined between the first and second stops, and the second and third stops. An inlet is defined through a wall of the case and communicates between the first chamber and a pressurized air source, and an outlet is defined through the wall of the case and communicates between the second chamber and the space in the barrel. The movable rod is moved between first and second positions to seal or introduce pressurized air into the barrel of the gun.

Abstract: A securing device for paint ball gun includes an adjustment member connected to a barrel and a positioning member has an end pivotably connected to the adjustment member.
