摘要： The invention relates to a control valve, a percussion device and a method of controlling a working cycle of a percussion device. A percussion device (1) for breaking rock includes an impact element (8) controlled by a control valve (2). The control valve includes a control element (5) arranged to control channels (7b) leading to a working pressure surface (9) of the impact element (8). The control element, during a working cycle of the control valve, is arranged to open and close pressure channels at several connecting moments so that during one working cycle of the valve, several impact pulses are arranged to be produced.

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： A single-stroke percussion device comprises a hollow cylindrical casing (1) with an inlet and an outlet opening (2, 3). A striker (1) is mounted inside the casing (1) so as to divide its internal cavity into an upper and a lower chamber (5, 6). A working instrument (7) is mounted in the casing (1) on the same side as the lower chamber (5), mounted in the upper part of the casing (1) is a grip (9), provided with channels and with an air distributing mechanism (8). A sleeve (12) with openings (13) is mounted on the casing (1) so as to form, together with the latter, a cavity (14). An air distributing bushing (15) spring-loaded in the axial direction is mounted inside the cavity (14). The outlet openings (3) of the casing (1) are situated at the same level as the openings (13) of the sleeve (12). Radial openings and grooves (17) are provided in the air distributing bushing (15) at the same level as the radial openings (16) on both surfaces of the air distributing bushing (15). The striker (4) spring-loaded on the same side as the lower chamber (5), is provided with at least one channel (18).
