Abstract: A pneumatic nail gun operated in automatic actuation mode includes a gun body, a trigger valve, and a shuttle valve. The gun body defines therein a main chamber and is provided with a forward air conduit and a return air conduit. The forward air conduit provides a path for the pressurized air in the main chamber to force a valve stem of the shuttle valve to conduct a forward movement for a drive stroke. The return air conduit provides a path for the pressurized air in the cylinder to force the valve stem to conduct a return movement after the nail gun has completed the drive stroke. By depressing an actuating bar of the trigger valve a single time, the valve stem can be forced to conduct repeated forward and return movements, and thus the nail gun can conduct repeated drive strokes for stably striking a nail.
