  • Publication number: 20200208622
    Abstract: A compressor includes a terminal cover. The terminal cover includes a first terminal protector protecting a first glass-sealed terminal assembly, a first power line guide guiding first power lines connected to the first glass-sealed terminal assembly, a first power line outlet through which the first power lines extend outward, a second terminal protector protecting a second glass-sealed terminal assembly, a second power line guide guiding second power lines connected to the second glass-sealed terminal assembly, and a second power line outlet through which the second power lines extend outward. The first power line guide guides the first power lines in a guiding direction away from the second terminal protector. The second power line guide guides the second power lines such that the second power lines bypass the first terminal protector and are directed in a direction identical to the guiding direction.

  • Patent number: 10677148
    Abstract: A variable displacement exhaust turbocharger is provided with a plurality of nozzle vanes that are rotatably supported by a nozzle mount, a drive ring that is interlocked with an actuator and fits to a guide part of the nozzle mount, a lever plate having one end coupled to the drive ring and the other end coupled to the nozzle vane, and a variable nozzle mechanism that varies the vane angle of the nozzle vane by rotating the drive ring. A bulge suppressing portion is provided for absorbing bulging occurring on an outer peripheral surface of the guide part, the bulging being caused by the press-fitting of a nail pin into a press-fitting hole in a direction slightly toward the rotational axis with respect to the guide section and following the axial direction of the nozzle mount.
