摘要： The present invention relates to a pulse generating device for inducing a shock wave in a tool, wherein the said pulse generating device comprises an impact means (201; 301) for transferring energy to a drill string (202) connected to the said tool, and wherein the energy transfer gives rise to the said shock wave, in which the said energy is mainly constituted by elastic energy stored in the impact means (201; 301) and/or an energy store. The device comprises control means for controlling the interaction of the impact means (201; 301) with the drill string (202), wherein the said control means for controlling the interaction of the impact means (201; 301) with the drill string (202) comprises a motor (207; 307), and wherein the said motor (207; 307) is designed to, through rotation, alternately open ducts for pressurization and depressurization of at least one drive surface (205) acting upon the said impact means. The invention is characterized in that the rotation axis of the said motor (207; 307) is arranged substantially coaxially with the drill string (202).

摘要： The invention relates to a method for controlling a pressure fluid operated percussion device comprising a working chamber for pressure fluid and in the working chamber a transmission piston installed movably with respect thereto so as to enable a tool installed in the percussion device to be pressed against a material to be broken in order to generate a stress pulse, and to a percussion device. The method comprises adjusting the length of the stress pulse by adjusting the time during which pressure influences the transmission piston. The percussion device comprises an adjustment element and adjustment means for adjusting the influence time of the pressure of the pressure fluid being fed via a control valve and influencing the transmission piston.

摘要： A control valve, an impact device for a rock breaking apparatus, and a method. The control valve (26) is an elongated piece with a central axis and radial outer and inner surfaces (Ros, Ris). The control valve comprises several control surfaces at axial distances from each other for controlling hydraulic fluid flows (Hff) in response to axial control movement (M). One or more radial surfaces of the control valve comprise one or more slanted surface (SS) longitudinal direction of which have oblique orientation in relation to the central axis (Ca) of the control valve. Then the control valve rotates or turns during a working cycle due to hydraulic flow effecting on the slanted surfaces.
