PROBLEM TO BE SOLVED: To reduce the power consumption of an inverter-driven compressor, and to suppress the generation of drain in the compressor.;SOLUTION: A secondary side of a check valve 54 arranged in an air flow passage 50 which reaches a consumption side from a discharge port 10b of a compressor body 10 is used as a supply flow passage 52, when the pressure Pd in the supply flow passage 52 is lower than non-load operation start pressure Pul, rotational speed control for making pressure in the supply flow passage 52 coincide with target pressure Pt is performed, and when the pressure Pd in the supply flow passage reaches the non-load operation start pressure Pul, control for transitioning to a non-load operation by which a discharge flow passage 51 is released in atmospheric air is performed. In the rotational speed control, when the compressor body 10 is brought into a prescribed "low-load operation" for performing a load operation in the vicinity of the lowest rotational speed, the rotational speed control is stopped, a rotational speed of a motor 15 is raised, pressure in the supply flow passage 52 is raised to the non-load operation start pressure Pul or higher, and the motor is caused to forcibly transition to the non-load operation.;COPYRIGHT: (C)2015,JPO&INPIT
