A positioning device having a chamber having a chamber exhaust valve in a first end and a chamber fluid inlet in a second end; a piston disposed in a chamber between the first end and the second end, the piston being slidable in the valve chamber between a first position toward the first end and a second position toward the second end; the fluid communication opening having a smaller cross-section area than the chamber exhaust valve; and a piston biasing spring urging the piston toward the chamber second end and away from the chamber first end, the piston biasing spring responsive to a fluid pressure differential between the first and second chamber ends above and below a predetermined level to move the piston into the first and second positions, respectively. Also, a power tool having a housing including a fluid supply inlet; a fluid operated motor assembly mounted in the housing, the motor assembly including a motor fluid inlet; a valve connecting the fluid supply inlet and the motor fluid inlet; the valve being operable between a first position permitting fluid communication between the fluid supply inlet and the motor fluid inlet and a second position restricting fluid communication between the fluid supply inlet and the motor fluid inlet; and a positioning device operatively connected to the valve, the positioning device having first and second positions corresponding to the valve first and second positions, respectively.

Solenoid controlled air tool

A tool is provided with an output extension head having parallel sets of drive trains drivingly connecting an input drive gear and an output socket gear. The drive trains each have individual idler gears in mesh with both the input drive gear and output socket gear to significantly increase the ultimate torque capacity of the tool without increasing the thickness of the gear components or the radial dimensioning of the output end of the extension head.
