ABSTRACT:
A semi-automatic fluid powered gun includes an elongated barrel having opposed front and rear open ends, and a projectile storage clip for storing a plurality of projectiles outside of the barrel and for sequentially positioning each projectile in line with the barrel adjacent the rear end. A transfer tube is supported to the rear of and in line with the barrel and is movable between a forward position in which it moves the positioned projectile into the barrel and prevents the other stored projectiles from being positioned in line with the barrel, and a rear position in which the transfer tube permits the next stored projectile to be positioned in line with the barrel. An elongated cylinder is positioned to the rear of and in line with the barrel and includes opposed front and rear open ends, and the transfer tube is received in the front end of the cylinder to provide fluid communication between the cylinder and the barrel when the transfer tube is in the forward position. A piston is received in the rear end of the cylinder and is movable within the cylinder relative to the transfer tube between forward and rear positions. The piston faces the transfer tube to define a chamber within the cylinder that is connected to a source of pressurized fluid by a passage. A valve is provided in the fluid passage for controlling the flow of fluid from the source to the chamber, and a hammer opens the valve to deliver pressurized fluid to the chamber so that the fluid acts forward through the transfer tube to fire the projectile from the front end of the barrel and rearward against the piston to move the piston to the rear position. A slide is interposed between the piston and the hammer for moving the hammer to the cocked position when the piston is in the rear position, and a trigger releases the hammer from the cocked position to initiate firing of the hammer.
