い。The first compression mechanism 1 is driven only by the engine, such as a vehicle, which is the first drive source, and the second compression mechanism 2 is the first.
Since it is driven only by the electric motor 25, which is a second drive source different from the drive source, the first compression mechanism 1 may be adapted only to the engine of a vehicle or the like having a large output, and the second compression mechanism has a small output. It may be adapted only to the electric motor 25. Therefore, in the hybrid compressor A, there is no difficulty in fitting the compression mechanism and the drive source. First compression mechanism 1 and second
The hybrid compressor A is downsized by being integrally assembled with the compression mechanism 2. Since the suction chamber 17 of the first compression mechanism 1 and the suction chamber 27 of the second compression mechanism 2 communicate with each other via the communication passage 33, the second compression mechanism 2 operates and the first compression mechanism 1 stops. The oil and the refrigerant that flowed back from the external refrigerant circuit and flowed into the suction chamber 17 of the stopped first compression mechanism 1 while the second refrigerant circuit is in operation are in operation via the communication passage 33
It is sucked into the suction chamber 27 of the compression mechanism 2 and does not accumulate in the suction chamber 17 of the stopped first compression mechanism 1. Therefore, there is no risk of the second compression mechanism 2 in operation becoming poorly lubricated, and there is no risk of compressing the liquid refrigerant when the first compression mechanism 1 in stop is activated.

排出される。Since the communication passage 33 extends between the lower part of the suction chamber 17 of the first compression mechanism 1 and the lower part of the suction chamber 27 of the second compression mechanism 2 of the hybrid compressor A in the operating state, it is stopped. Even if the oil or the refrigerant that has flowed into the suction chamber 17 of the first compression mechanism 1 inside collects in the lower part of the suction chamber 17, the oil or the refrigerant still flows through the communication passage 33 and the second compression mechanism 2 that is operating.
Is sucked into the lower part of the suction chamber 27 without any trouble and discharged from the suction chamber 17.

い。A suction port similar to the suction port 16a may be formed in the housing 26 of the second compression mechanism 2. In this case, when the first compression mechanism 1 is operating and the second compression mechanism 2 is stopped, the oil and a part of the refrigerant that flow back from the external refrigerant circuit to the hybrid compressor A pass through the branch portion of the return path. While flowing into the suction chamber 27 of the second compression mechanism 2 which is stopped,
The oil and the refrigerant pass through the communication passage 33 and are in operation.
Since it is sucked into the suction chamber 17 of the compression mechanism 1, it does not accumulate in the suction chamber 27 of the second compression mechanism 2. Therefore, there is no risk of the first compression mechanism 1 in operation becoming poorly lubricated, and there is no risk of compressing the liquid refrigerant when the second compression mechanism 2 in stop is activated.

The suction chamber may be shared by the first compression mechanism 1 and the second compression mechanism 2. If the first compression mechanism 1 and the second compression mechanism 2 share the suction chamber, when the oil or refrigerant recirculated from the external refrigerant circuit flows into the suction chamber, it is taken into the operating compression mechanism and does not accumulate in the suction chamber. Therefore, there is no risk of the lubrication failure of the compression mechanism in operation, and there is no risk of compressing the liquid refrigerant when the compression mechanism in stop is activated.

液冷媒を圧縮する恐れは無い。As described above, in the hybrid compressor according to the present invention, the first compression mechanism is driven only by the first drive source, and the second compression mechanism is driven only by the second drive source. The first compression mechanism only needs to be adapted to the first drive source, and the second compression mechanism only needs to be adapted to the second drive source. Therefore, in the hybrid compressor according to the present invention, there is no difficulty in fitting the compression mechanism and the drive source. Since the suction chamber of the first compression mechanism and the suction chamber of the second compressor communicate with each other via the communication passage, one of the first compression mechanism and the second compression mechanism operates and the other stops. At times, even if the oil or refrigerant that has flowed back from the external refrigerant circuit flows into the suction chamber of the compression mechanism that is stopped, it is sucked into the suction chamber of the compression mechanism that is operating through the communication passage, and the suction of the compression mechanism that is stopped It doesn't collect in the room. Therefore, there is no risk of the lubrication failure of the compression mechanism in operation, and there is no risk of compressing the liquid refrigerant when the compression mechanism in stop is activated.
