Abstract (en)
[origin: WO2018029025A1] The invention relates to a hand-held power tool 1 with a tool holder 2 for holding a tool 3 and a pneumatic percussive mechanism 8 for periodically generating percussions on the tool 3 held in the tool holder. The percussive mechanism 8 comprises a guide tube 15, an excitation piston 13, a striker 9, a pneumatic chamber 14 which is enclosed in the guide tube by the excitation piston 3 and the striker 9, and a compensating opening 17 in the guide tube for ventilating the pneumatic chamber 14. A cap covers the compensating opening 17 on an exterior of the guide tube 15. The cap is open in an opening direction largely tangential to the guide tube 15.
