AbstractSolenoid valves (16, 17), which permit a fluid to flow in the direction for compression, are provided in a suction pipe (7) and a discharge pipe (9) of a turbocompressor (1). One end of a bypass pipe (20) is connected between the solenoid valve (16) in the suction pipe (7), and an impeller chamber (6), and the other end of the bypass pipe (20) is connected between the solenoid valves (17) in the discharge pipe (9) and the impeller chamber (6). Provided in a bypass pipe (20) is a solenoid valve (21) that closes at the time of compressing action of the turbocompressor (1) and opens at the time of stopping action of the turbocompressor (1).
