ABSTRACT:
An air path arrangement for a pneumatic nail gun includes cylinder received in a barrel and a handle is connected to the barrel. A space is defined between the cylinder and an inner periphery of the barrel. A connection path communicates between the interior and a first partition of the chamber. A side path communicates between a space between the cylinder and an inner periphery of the barrel, and a second partition of the chamber. The first partition communicates with an inlet and an outlet in the handle. A movable member, a guide member, a valve, an axle and a base are received in the chamber. The guide member is located between the first and second partitions. The guide member has apertures which communicates with the first and second partitions so that the movable member and the valve are movably received in the first partition and the second partition.
