<p>A screw compressor (1) includes, in a casing (10), a compression mechanism (20) having a screw rotor (30) and a gate rotor (40). The casing (10) includes a low pressure chamber (12) in which a low pressure refrigerant to be suctioned into the compression mechanism (20) flows, and a high pressure chamber (11) in which a refrigerant compressed by the compression mechanism (20) flows. The bypass mechanism (50) includes an inside bypass passage (52) connecting the high pressure chamber (11) and the low pressure chamber (12), and an inner valve (53).</p> |
