PURPOSE:To enable a compressor to be used more effectively, by energizing an electromagnetic valve means by a computer unit when an air tank on the one side is filled with air of a prescribed pressure so that an air tank on the other side is filled with air. CONSTITUTION:When a value of a pressure sensor 9 is less than a standard compressed pressure where a piston 1a moves reciprocatingly, an electromagnetic valve 7 is opened and an electromagnetic valve 8 is closed by the operation of a CPU 10 so that an air tank 5 is filled with air. When a value of the pressure sensor is greater than the standard compressed pressure, the electromagnetic valve 7 is closed and the electromagnetic valve 8 is opened by the CPU 10 so that an air tank 6 on the other side begins to be filled with air. When a pressure regulator 12 has a pressure greater than the standard compressed pressure, a pipe 13 is opened, air is supplied into an unloader valve 11, an intake valve 2a is opened, a cylinder 1b is opened to the atmosphere, and the piston 1a is actuated without load, whereby a compressor is used more effectively.
