The hydraulic rock drill is a rock drilling machine that uses high-pressure oil as a power to push the piston to impact the drill and attaches an independent rotary mechanism. The piston is controlled by the valve (and also has no valve) to reciprocate. Since the oil pressure is much higher than the gas pressure, it is more than 10MPa.
