  • the electric scroll compressor includes a discharge housing which includes a discharge port and in which a compression portion (compression mechanism) configured such that a fixing scroll and a movable scroll are disposed so as to face each other is accommodated, a suction housing which includes a suction port, and an intermediate housing which interposed between the discharge housing and the suction housing and in which an electric motor is accommodated along with the suction housing, in which the intermediate housing is configured so as to include a motor fixing portion in which a portion of the electric motor is accommodated and fixed, and a bearing support portion (end plate) which is integrally formed on the discharge housing side of the motor fixing portion and supports a drive shaft via a bearing.

  • the pin is press-fitted to the substrate of the swing scroll so as to be fixed, since drivability of the swing scroll is important, the swing scroll is lightly and thinly formed, and stiffness of the swing scroll is lower than that of a fixing member such as the housing. Accordingly, when the pin is press-fitted, there is a disadvantage that the press-fitted location of the swing scroll is deformed and the pin is tilted, or when the pin comes into contact with a portion engaging with the pin and receives a radial load, there is a disadvantage that the pin is tilted by the radial load.
  • the diameter of the housing may be deformed to be increased when the electric motor is fixed to the housing. Accordingly, in order to increase assembly accuracy of the pin (in order to prevent titling of the pins), preferably, the fixing location of the pin is influenced by the deformation of the housing as little as possible.
  • the present invention is made in consideration of the above-described circumstances, and a main object thereof is to provide an electric scroll compressor provided in which accuracy during assembly of a pin increases and the performance or the reliability of a compressor can be improved in a case in which a configuration in which the pin is engaged is adopted as a rotation preventing mechanism of a swing scroll.

  • the holes may be configured of a fluid passage through which a fluid to be compressed, which is compressed in the compression chamber, flows.
  • the holes are the passage of the fluid to be compressed, it is not necessary to form holes for preventing deformation in addition to the holes of the fluid passage.
  • a rib extending in the radial direction may be formed on the end plate, and the pins may be fixed to the portion in which the rib is formed.
  • the pin is fixed to the portion in which the rib of the end plate is formed, the pin is fixed to the portion having higher stiffness, and it is possible to further suppress the deformation of the end plate.
