Abstract

A suspension mechanism for a motor of a combustion chamber fan in a combustion powered hand tool constructed and arranged for driving a driver blade to drive a fastener into a work piece, the tool generating an upward axial acceleration of the motor upon a combustion in the chamber, a subsequent reciprocal axial acceleration of the motor when the piston bottoms out on a bumper, at least one of the accelerations causing the motor to oscillate relative to the tool, the suspension mechanism includes a suspending portion configured for providing progressive dampening to the motor upon the generation of the axial accelerations.
