Abstract

Regulating compression capability to a load is performed by a inverter (15) that regulates the revolution number of an electric motor (11). This makes unload control in the capability regulation unnecessary, preventing operational efficiency from lowering. Further, a capacity control valve for capacity control is eliminated for a simplified valve controlling mechanism. Regulating a variable inner volume ratio achieves the highest compressor efficiency corresponding to operating condition (capability). When a low inner volume ratio command is issued, a slide valve (19) is moved by a compression portion controller (27) in an axial direction toward the electric motor (11). This advances the completion time of a compression step to advance the discharge of a compressed gas. When a high inner volume ratio command is issued, the slide valve (19) is moved in an axial direction toward a piston (25), which delays the time of completion of the compression step to delay the discharge of a compression gas.
