摘要： The invention relates to a percussion device of a rock breaking device, a method for controlling the percussion device and a rock drilling unit. The percussion device (11) comprises a percussion piston (33), the work cycle of which is controlled by means of a control valve (40, 77). During the movement of the percussion piston, a pressure pulse is generated by closing a pressure connection (Y1, Y2) from at least one impulse space (44, 45) surrounding the percussion piston. The pressure pulse is used to change the position of the valve from one extreme position to an other. The impulse space is an annular space defined in a radial direction by the percussion piston and the frame (25).The frame is further provided with at least one impulse channel (58, 59) for transmitting a pressure pulse to the pressure surface of the control valve.

摘要： A pressure fluid operated impact device comprising a frame (2) whereto a tool (3) is mountable movably in its longitudinal direction, and control means (7) for controlling pressure fluid feed to the impact device (1), as well as a method of generating a stress pulse in a pressure fluid operated impact device. The impact device (1) comprises a working chamber (8) and a transmission piston (9) moving therein. Energy charging means for charging energy of pressure fluid and the control means are coupled to allow periodically alternately pressure fluid to flow to the working chamber (8) and, correspondingly, to discharge pressure fluid from the working chamber (8). In the method, pressure fluid is fed to the working chamber (8), which produces a force pushing the transmission piston (9) in the direction of the tool (3), thus generating a stress pulse in the tool (3).
