    Abstract: The invention relates to a percussion device comprising two percussion pistons alternately making a percussion motion and a control valve for controlling the percussion pistons. The control valve (7) comprises a slide (8) affected by a force so that the slide is generally in a first position, but moves at the end of the percussion motion of the first percussion piston from the first position to a second position and correspondingly back to the first position at the end of the percussion motion of the second percussion piston (4).

    Abstract: A method for controlling the operating cycle of an impact device, and an impact device. Percussion piston position is measured using a sensor (11) from which the measurement data is transmitted to a control unit (12) of the impact device, which in turn controls an electrically driven control valve (10).
