PURPOSE:To obtain the most efficient discharging amount in accordance with a discharging pressure by a method wherein a vibration frequency and the rest time rate of an alternate signal, adapted to the detected discharging pressure of the compressor, are read out to generate an alternate current corresponding thereto. CONSTITUTION:A piston 21 effects a reciprocal vibrating motion by supplying an alternate execiting current to movable coils 31, 32. Accoding to this motion, external air is sucked through a suction pipe 27 and the compressed air is discharged out of a discharging pipe 26. The operation of the compressor 10 may be controlled most efficiently by controlling three parameters of the frequency of rectangular wave, generated from a constant voltage electric source through an inverter, and the reset time rates t1/T1, t2/T2. |
