| Zusammenfassung: | The tool such as an impact wrench has a pulse unit (6) having a hydraulic impact mechanism (7), a hydraulic rotor (26), a cylinder and hydraulic vanes (23), which together are driven by a compressed air motor as the drive unit. A working volume within the hydraulic impact mechanism is connected to an additional volume formed outside of it. The additional volume can be varied independently of the pressure. The hydraulic impact mechanism is arranged between the drive unit and a tool holder. The additional volume has a setting part (2) limiting at one end. |
