| description | PROBLEM TO BE SOLVED: To provide a rotary two stage compressor capable of suppressing pressure pulsation in an intermediate flow path by improving followability of a refrigerant introduced into a high stage compression part, and capable of preventing a drop of operation efficiency during low load operation.SOLUTION: A two stage compressor 100 as the rotary two-stage compressor of internal high-pressure type includes a low stage cover 19 that covers a low stage outlet port 16 and forms a low stage discharge space 20 therein. Further, in the two stage compressor 100, an intermediate passage 51 that connects the low stage discharge space 20 and the high stage compression chamber 35 are formed in a compression mechanism 3. Further, the two-stage compressor 100 includes a bypass mechanism (bypass port 23, a bypass valve 24, and a bypass valve guard 25) in the low stage cover 19, which opens when a load is smaller than a predetermined load and which connects the low stage discharge space 20 and a discharge pressure space 53. |
