Abstract
A fastener driving tool that forces air from its variable venting volume beneath the piston of the working cylinder and directs that forced air through passageways and toward an electronic controller and/or an electric motor before being vented to atmosphere, thereby drawing heat away from those components during an operational cycle of the movable piston. When the piston returns to its initial position, environmental air is drawn through the same passageways, again past the electronic controller and/or electric motor, thereby twice cooling these “hot” components during a single operational cycle.
