狭いスペースへの取り付けが困難であった。However, since the conventional oil separator is provided separately from the functional parts of the refrigeration cycle, it has the following problems. Since oil return piping for returning oil is required, the cost of the refrigeration cycle provided with the oil separator increases. A connection means is required for each of the refrigerant inflow part, the refrigerant outflow part, and the oil return pipe of the oil separator, which also increases the cost of the refrigeration cycle provided with the oil separator. Since a space for attaching and detaching the oil separator and a space for passing the oil return pipe are required,
It was difficult to install in a narrow space.

る。The oil separator of the present invention employs the following technical means. The oil separator includes a refrigerant compressor body that receives the rotational power and sucks, compresses, and discharges the refrigerant, and an inflow joint that introduces the refrigerant that the refrigerant compressor body draws, and the refrigerant compressor body discharges the refrigerant. It is mounted between a connection joint provided with an outflow joint for outflowing the refrigerant. The oil separator guides the suction refrigerant guided to the connection joint to the refrigerant compressor body, and the discharge refrigerant of the refrigerant compressor body to separate the gas refrigerant and the oil into a gas-liquid separator. A chamber, a discharge refrigerant passage that guides the gas refrigerant separated in the gas-liquid separation chamber to the connection joint, and an oil passage that depressurizes the oil separated in the gas-liquid separation chamber and guides it to the suction refrigerant passage.

る。When the refrigerant compressor body receives rotational power,
The refrigerant sucked from the inflow joint is sucked through the suction refrigerant passage, compressed and discharged. The discharged refrigerant flows into the gas-liquid separation chamber of the oil separator and is gas-liquid separated into gas refrigerant and oil. Then, the gas refrigerant is guided to the connection joint through the discharge refrigerant passage and discharged from the outflow joint. On the other hand, the oil separated in the gas-liquid separation chamber is guided to the suction refrigerant passage through the oil passage, and is again sucked into the refrigerant compressor body together with the refrigerant sucked from the inflow joint.

さく済む。Since the oil separator does not require an oil return pipe, the cost of the refrigeration cycle can be suppressed lower than in the conventional case. Further, since the oil separator is attached by being sandwiched between the refrigerant compressor body and the connection joint when the refrigerant compressor is assembled, the assembly cost can be suppressed as compared with the conventional case. That is, the refrigeration cycle using the oil separator of the present invention can reduce the cost as compared with the refrigeration cycle using the conventional oil separator. Further, since the oil separator is mounted by being sandwiched between the refrigerant compressor main body and the connection joint, connection pipes and the like are not required, and as a result, the installation space of the oil separator is very small.
