and two electromagnetically driven spool control valves that control the opening and closing of the logic valves, and the control hydraulic pressure that opens and closes the logic valves and the hydraulic oil that opens and drives the intake and exhaust valves are supplied from a high-pressure pressure accumulator. A valve train for an internal combustion engine, characterized in that the intake and exhaust valves are closed by a spring force stored as the intake and exhaust valve driving piston lifts to open the valve. (2) A piston for driving the intake and exhaust valves of a valve train of an internal combustion engine that has a hydraulic pressure source and a pressure accumulator that pressurizes and stores hydraulic oil, and controls the hydraulic oil in the pressure accumulator to drive the intake and exhaust valves. Two logic valves that communicate with each other open and close a high-pressure oil passage communicating with the upper part, and two electromagnetically driven spool control valves that control opening and closing of the two logic valves, and open and close the logic valves. Control hydraulic pressure and hydraulic oil for driving the intake and exhaust valves to open are supplied from a high-pressure pressure accumulator, and the intake and exhaust valves are opened by the spring force stored as the intake and exhaust valve driving piston lifts to open the valves. A valve operating system for an internal combustion engine configured to close a valve, characterized in that a check valve is provided between the pressure accumulator and the open logic valve.
