Abstract
A fastener driving tool that uses pressurized gas to drive a piston that causes a driver blade to force a fastener into a workpiece, and then uses an induction coil to “lift” the piston (as an armature) back toward the top, pre-drive position. The pressurized gas is not vented to atmosphere, but is instead re-used for multiple drive cycles. An optional induction coil can have multiple stages. A more preferred induction coil includes multiple stages, in which some of those coil stages extend beyond the end stroke of the piston, past a “ready” position for that piston.
