A driving tool with tool portion and a gas delivery system. The tool portion includes a linear pneumatic motor that is configured to propel a driver blade. The gas delivery system is configured to deliver a pressurized gas, such as compressed air or nitrogen, to the tool portion for use in operating the linear pneumatic motor. The gas delivery system includes a first inlet, which is connectable to a first source of compressed gas, such as a stationary air compressor, a second inlet, which is connectable to a second source of compressed gas, such as a tank mounted to the tool portion, and a directional valve for selecting between the first and second inlets.

A driving tool comprising: a housing having a handle and a pressure chamber;a pneumatic linear motor housed in the housing and having an output member, the pneumatic linear motor being configured to receive compressed gas from the pressure chamber;a driver blade disposed in the housing and couple
1. A driving tool comprising: a housing having a handle and a pressure chamber;a pneumatic linear motor housed in the housing and having an output member, the pneumatic linear motor being configured to receive compressed gas from the pressure chamber;a driver blade disposed in the housing and coupled to the output member for movement therewith along a driver axis;a first inlet that is adapted to be coupled to a first source of compressed gas;a second inlet that is adapted to be coupled to a second source of compressed gas;a directional valve in fluid communication with the pressure chamber, the directional valve being selectively operable in first and second conditions, wherein operation of the directional valve in the first condition establishes a first flow path in which the first inlet is coupled in fluid communication to the pressure chamber and fluid communication between the pressure chamber and the second inlet is inhibited, and wherein operation of the directional valve in the second condition establishes a second flow path in which the second inlet is coupled in fluid communication to the pressure chamber and fluid communication between the pressure chamber and the first inlet is inhibited;a shut-off valve disposed between the second inlet and the directional valve; anda regulator disposed in fluid communication between the shut-off valve and the directional valve. 2. The driving tool of claim 1, wherein the directional valve is configured to automatically select between the first and second flow paths based on a set of pre-defined criteria. 3. The driving tool of claim 2, wherein the set of pre-defined criteria comprises a pressure differential. 4. The driving tool of claim 1, wherein the directional valve is manually operated. 5. The driving tool of claim 1, further comprising a magazine coupled to the housing, the magazine being configured to hold a plurality of fasteners and to sequentially feed the fasteners into a position where they can be engaged by the driver blade to be driven into a workpiece. 6. The driving tool of claim 5, wherein the second source of compressed gas comprises a tank that is mounted to at least one of the housing and the magazine. 7. The driving tool of claim 6, further comprising a clamp that is selectively operable to fix the tank to the housing, the magazine or both the housing and the magazine. 8. A driving tool comprising: a housing having a handle and a pressure chamber;a pneumatic linear motor housed in the housing and having an output member, the pneumatic linear motor being in fluid communication with the pressure chamber;a driver blade disposed in the housing and coupled to the output member for movement therewith along a driver axis;a magazine coupled to the housing, the magazine being configured to hold a plurality of fasteners and to sequentially feed the fasteners into a position where they can be engaged by the driver blade to be driven into a workpiece; anda gas feed system comprising: a directional valve having a first inlet, a second inlet and an outlet, the outlet being coupled in fluid communication with the pressure chamber, the first inlet being configured to be coupled in fluid communication to a first source of compressed gas;a tank coupled to the housing and coupled in fluid communication with the second inlet, the tank being configured for use as a second source of compressed gas;a shut-off valve disposed between the second inlet and the directional valve; anda regulator disposed in fluid communication between the shut-off valve and the directional valve. 9. The driving tool of claim 8, wherein the directional valve is configured to automatically select between the first and second flow paths based on a set of pre-defined criteria. 10. The driving tool of claim 9, wherein the set of pre-defined criteria comprises a pressure differential. 11. The driving tool of claim 8, wherein the directional valve is manually operated. 12. The driving tool of claim 8, further comprising a clamp that is selectively operable to fix the tank to the housing, the magazine or both the housing and the magazine. 13. A method for operating a driving tool, the driving tool having a housing, a pneumatic linear motor, a driver blade and a gas feed system, the housing having a pressure chamber, the pneumatic linear motor being housed in the housing and being coupled in fluid communication with the pressure chamber, the pneumatic linear motor having an output member to which the driver blade is coupled for movement therewith along a driver axis, the gas feed system comprising a directional valve, a pressure limiting device, a shut-off valve and a regulator, the directional valve having a first inlet, a second inlet and an outlet, the outlet being coupled in fluid communication with the pressure chamber, the method comprising: coupling the first inlet to a first source of compressed gas;coupling a gas tank to the second inlet such that the pressure limiting device is disposed between the regulator and the gas tank,. the gas tank being a second source of compressed gas; andsecuring the gas tank to the housing;operating the directional valve in a first condition to direct compressed gas from the first source of compressed gas to the pressure chamber;operating the directional valve in a second condition to direct compressed gas from the gas tank to the pressure chamber; andadjusting the regulator to change the pressure of the gas entering the pressure chamber when the directional valve is in the second condition.
