Abstract
A fastener driving tool and method for driving fasteners into a substrate is disclosed. The tool includes a working piston that is capable of being moved abruptly translationally by igniting an ignitable mixture in a combustion chamber so as to drive a fastener, such as a stud or a nail. The volume of the combustion chamber is adjustable. In order to further improve the operation and/or energy efficiency of the fastener driving tool, the fastener driving tool also includes a control device which is connected in a control relationship to an adjusting device for adjusting the combustion chamber volume and to a metering valve device for metering fuel gas.
