Abstract (en)
[origin: WO2015049133A1] A handheld power tool 1 has a tool holder 2 for holding a tool along a working axis 11. A motor-driven, pneumatic percussion mechanism 6 has an exciter 17, driven by a motor 5, a striker 14, coupled to the exciter 17 by way of a pneumatic chamber 19, and an intermediate striker 22, arranged on the working axis 11 behind the striker 14 in the striking direction 12. A ventilating opening 30 connects a cavity 29 between the striker 14 and the intermediate striker 22 to the surroundings. A valve 38, closing the ventilating opening 30, is open as a result of being actuated by the intermediate striker 22 when the intermediate striker 22 has been pushed into its working position counter to the striking direction 12.
