Abstract: A motor-operated compressor is provided that may include an orbiting scroll and a rear housing supporting a rear surface of the orbiting scroll. The rear housing may be provided with a discharge space communicating with a discharge port of the orbiting scroll formed at a central portion of a surface facing the orbiting scroll, an oil separation space formed at one side of the discharge space to communicate with the discharge space, and an oil storage space formed at an edge portion of the surface facing the orbiting scroll. An oil return passage may be provided between the oil separation space and the oil storage space, so as to guide oil separated in the oil separation space to the oil storage space. Accordingly, a space for storing oil separated from a discharged refrigerant may be sufficiently secured while allowing the rear housing defining the oil storage space to be easily fabricated.

Abstract: A synthetic resin bearing and a scroll compressor (100, 200) using the same are provided. In the synthetic resin bearing as a journal bearing (122, 132, 163, 228, 234) fixed to an orbiting scroll (160, 240) or a main frame (120) and relatively rotated with respect to a rotational shaft in a scroll compressor, the journal bearing is made of a PEEK material, and a thickness t of the journal bearing is smaller than a thickness t1 with which a temperature in a contact surface thereof with the rotational shaft (143, 226) during an operation of the scroll compressor corresponds to a glass transition temperature.

Abstract: A scroll compressor is provided that includes an oil recollecting pump to recollect oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor, and a differential pressure hole formed at a position where it communicates with compression chambers after a suction completion timing, such that oil stored in an inner space of the shell can be supplied into the compression chambers using a pressure difference between a high-pressure inner space of the shell and a low-pressure compression chambers, resulting in allowing oil to be smoothly supplied to a compression unit even during low-speed driving of the compressor and preventing an occurrence of a suction loss due to oil.

Abstract: The present invention provides a turbocompressor and a method for controlling same, the turbocompressor comprising: a driving unit for enabling generation of rotational power for compressing refrigerant; a shaft extending in one direction and installed in the driving unit to be able to rotate by means of power generated by the driving unit; and first to third compression units installed on the shaft from one side of the shaft. The first compression unit comprises a first impeller rotated by power from the driving unit such that refrigerant discharged from an evaporator can be suctioned, and the suctioned refrigerant can be compressed and discharged. The second compression unit comprises a second impeller rotated by power from the driving unit such that refrigerant discharged from the first compression unit can be suctioned, and the suctioned refrigerant can be compressed and discharged. The third compression unit comprises a third impeller. The third impeller makes it possible to suction refrigerant discharged from the second compression unit, to compress the suctioned refrigerant, and to discharge same to the outside. Alternatively, the third impeller makes it possible to provide the refrigerant while bypassing the first compression unit.
