摘要： The invention relates to a control valve, a percussion device and a method of controlling a working cycle of a percussion device. The percussion device (1) used for breaking rock comprises an impact element (8), which is controlled by a control valve (2). The control valve comprises a control element (5), which is arranged to control channels (7b) leading to a working pressure surface (9) of the impact element (8). The movement of the control element to its extreme position is arranged to form a closed pressure space, where pressure medium compresses and converts kinetic energy of the control element into pressure energy. The pressure energy is re-converted into kinetic energy and utilized when the control element changes its direction.

摘要： The invention relates to a method and software product for controlling a percussion device belonging to a rock-drilling machine, and to a percussion device. The impact frequency of the percussion device (7) is set so that the percussion device (7) forms a new compression stress wave (p) to the tool (8) always when reflected waves (h) from the previous compression stress waves reach a first end (8a) of the tool. This requires that the impact frequency be set proportional to the propagation time of the stress wave, whereby the length of the used tool (8) and the propagation velocity of the stress wave in the tool material are to be noted.
