Abstract: A pneumatic nailer system for use with a compressor having a main storage tank, includes a first air hose connected at one end to the compressor, a supplemental air storage tank connected to an opposite end of the first hose, and connected at a supply end to at least one second air hose, a pneumatic nailer connected to a tool end of the at least one second air hose, such that the supplemental air storage tank is located between the compressor and the at least one nailer. The supplemental air storage tank enables the pneumatic nailer(s) connected to the supplemental air storage tank to provide consistent drive energy for driving fasteners while reducing the internal air storage volume and overall size of the nailer.

Abstract: A pneumatic nailer includes a tool housing enclosing a cylinder with a reciprocating drive piston, and having a trigger and a workpiece contact element both connected to a trigger valve. A valve cap is mounted to the housing and includes a cycle valve and a dump valve, each valve reciprocating in a respective valve chamber. The dump valve controls drive pressure for the drive piston, the cycle valve controls the return of the dump valve to allow piston return. The valve cap and the valves are constructed and arranged such that the piston is returned to a start position independent of positions of the trigger or the workpiece contact element.
