PURPOSE:To prevent a pulsating current from occurring at the time when a high pressure liquid is fed and a pressure reduced liquid is discharged, by connecting a cylinder chamber of a plunger type cylinder for pressure medium use to each of medium feeding and discharging parts used for low and high pressures via plural valves. CONSTITUTION:When a supplying valve 12 is opened, then a selector valve 15 is switched to a first position at the left, the supply of a high pressure coal liquefied product solution to a cylinder 14 from a gas-liquid separation tower 5 at the high pressure side gets starting, and as a result, plungers 11a and 14a are energized to the right whereby a pressure medium is raised up in pressure and fed to a hydraulic motor 27 from the cylinder 14 via the selector valve 15 and a line 42. A combined motor and generator GM is coupled with this hydraulic motor 27 so that pressure energy is recovered as electric energy. |
