  • Patent number: 9897091
    Abstract: In a compressor of the present invention, an intermediate pressure port through which a first discharge chamber and a motor chamber communicate with each other is formed in a front housing. A refrigerant having an intermediate pressure is discharged to the first discharge chamber. Consequently, it is possible to guide the refrigerant having the intermediate pressure in the first discharge chamber to the motor chamber, and cool an electric motor, which generates heat during actuation, with the refrigerant having the intermediate pressure. In the compressor, a first impeller and a second impeller are disposed such that large diameter portions of the first impeller and the second impeller face each other. The second impeller is smaller in diameter than the first impeller.

  • Patent number: 9520759
    Abstract: A motor-driven compressor that includes a metal housing accommodating a compression unit and an electric motor, a cover coupled to the housing, wherein the cover includes a resin portion and a metal shield, and the shield blocks electromagnetic noise, and a bolt that couples the cover to the housing. The housing and the cover define an accommodating chamber that accommodates a motor driving circuit that drives the electric motor. The cover includes an insertion hole into which the bolt is insertable. The shield includes a seat that surrounds the insertion hole and is held between the bolt and the housing. The cover is configured to allow for an axial force of the bolt to be applied to the seat and not to the resin portion.

  • Patent number: 9353624
    Abstract: In a motor-driven scroll compressor of the present invention, a double-sided sliding bearing is provided a space between a drive bush and a boss portion. The double-sided sliding bearing has a cylindrical outer sliding member that is provided in the boss portion, and a cylindrical inner sliding member that is provided in the bush portion. In an outer boundary zone of an inner circumferential surface of the boss portion and an outer circumferential surface of the outer sliding member, and an inner boundary zone of an inner circumferential surface of the inner sliding member and an outer circumferential surface of the bush portion, relative rotation is generated. The outer sliding member and the inner sliding member have different lengths in an axial direction, and thereby form a first and a second steps at both ends in the axial direction.

  • Patent number: 9068570
    Abstract: A motor-driven compressor includes a back pressure region that pushes a movable scroll against a fixed scroll. The back pressure region is located at a side of the movable scroll located proximate to an opposing member. A defining portion, which is arranged on a movable end face, contact an opposing end face to define the back pressure region and a suction pressure region. The opposing member includes a communicating portion. An orbiting motion of the movable scroll moves the defining portion. This intermittently communicates the communicating portion with the back pressure region and the suction pressure region.
