摘要： A rotary compressor (100) includes a compression mechanism (3), a motor (2), a suction path (14), a back-pressure chamber (18), a return path (16), an inverter (42), and a controller (44). A check valve (73) of a reed valve type for opening and closing a return port (3c) of the compression mechanism (3) is disposed in the back-pressure chamber (18). The return path (16) functions to return a working fluid to the suction path (14) from the back-pressure chamber (18). A volume-varying valve (17) is provided in the return path (16). The volume-varying valve (17) allows the working fluid to flow through the return path (16) when the suction volume of the compression mechanism (3) should be set relatively small, and precludes the working fluid from flowing through the return path (16) to increase the pressure in the back-pressure chamber (18) when the suction volume of the compression mechanism (3) should be set relatively large.

摘要： The present invention provides a capacity-control refrigeration cycle device capable of efficiently vary capacity, and in any of a full operation mode in which capacity of the refrigeration cycle device is not controlled and an operation mode in which the capacity is controlled, all of refrigerants are discharged into a hermetic container 1 and then, the refrigerants pass through a discharge path 11 and are guided to outside of the hermetic container 1. After a refrigerant and oil are sufficiently separated in the hermetic container 1, the refrigerant is discharged to outside of the hermetic container 1. Therefore, efficiencies of a condenser 300 and an evaporator 600 are not deteriorated. Since it is possible to reduce an amount of oil taken outside of the hermetic container, it is possible to stably secure oil in an oil reservoir 22, and to prevent bite of parts of a compressing mechanism and to prevent abnormal wearing.
