Flywheel configuration for a power tool

摘要

A driving tool with a flywheel (42), a driver (32), an actuator (41) and a roller that is moveable between an unactuated position and an actuated position. Positioning of the roller in the actuated position forces an engagement surface on the driver into contact with a rotating edge of the flywheel to transfer energy from the flywheel to the driver so that the driver will translate along an axis. The actuator at least partially initiates movement of the roller from the unactuated position to the actuated position.
