Abstract (en)
[origin: WO2017045972A1] 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 (2) can be generated particularly by means of a charging element (7). The combustion chamber comprises at least a first sub-housing (2a) and a second sub-housing (2b) that can be moved in an axial direction relative to the first sub-housing (2a), the two sub-housings (2a, 2b) being sealed from each other by means of at least one first seal (15). A contact force can be applied to the seal (15) in the axial direction, said contact force increasing monotonically with the positive pressure in the combustion chamber (2).
