| description | 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. |
