Abstract (en)
[origin: WO2017108750A1] The invention relates to a driving-in device comprising a driving-in piston (4) which is guided in a cylinder (3) for driving a nail element into a workpiece and comprising a combustion chamber (2) which is arranged on the driving-in piston (4) and which can be filled with an ignitable combustion gas mixture. An overpressure of the combustion gas mixture can be generated in the combustion chamber (2) by means of a charging element (7), and the driving-in piston (4) is sealed against an inner wall of the cylinder (3) by means of a first seal (14) during the driving-in movement. The driving-in piston is sealed from the combustion chamber (2) by means of a second seal (15), which is loaded axially to a piston axis (A), in a starting position.
