摘要： A hydraulic control system for use with a rock drill is adapted to sense a pressure build-up in the drill's rotation motor and in response thereto, to reverse the direction of feed of the feed motor as well as to supply hydraulic fluid to a shank cylinder on the rock drill. Supplying hydraulic fluid to the shank cylinder assists in freeing the drill from the rock.

摘要： A pressure-fluid-operated percussion device includes a frame allowing a tool to be arranged movably in its longitudinal direction. Pressure liquid is fed to the percussion device and returned to a pressure liquid tank. A stress pulse is produced in the tool utilizing pressure of the pressure liquid. A pressure liquid source maintains pressure in the working pressure chamber. Pressure liquid is intermittently fed to the percussion device such that the pressure liquid pushes a transmission piston into a predetermined backward position. Pressure liquid is alternately discharged rapidly from the percussion device so that the pressure of the pressure liquid in the working pressure chamber and the pressure liquid flowing from the pressure liquid source pushes the transmission piston towards the tool, generating a stress pulse in the tool.
