Abstract (en)
[origin: EP2394793A1] The tool i.e. hammer drill (1), has a striker (20) i.e. anvil, guidable along an axis (8) parallel to an impact direction (9). A volume of a pneumatic chamber is variable with a movement of the striker along the axis. A valve (50) i.e. non-return valve, is actuatable based on a movement of the striker. The valve is actuatable to open during moving the striker in the impact direction and is actuatable to throttle or close during moving the striker against the impact direction. The valve is openable for an air flow into the chamber and throttled or blocked for the air flow out of the chamber. An independent claim is also included for a method for controlling a machine tool.
