Abstract (en)
[origin: WO2017045967A1] The invention relates to a driving-in tool, comprising a driving-in piston (4), guided in a cylinder (3), for driving a nail element into a workpiece, and a combustion chamber (2) which is arranged at the driving-in piston (4) and can be filled with an ignitable fuel-gas mixture. A positive pressure of the fuel-gas mixture in the combustion chamber can be produced by a movement of the driving-in piston (4). At least one of the two, the combustion chamber (2) or the cylinder (3), is connected to an external space via a valve member (15), the positive pressure of the fuel-gas mixture produced by the driving-in piston being selectively adjustable by means of the valve member (15).
