  • Publication number: 20200109711
    Abstract: A scroll compressor includes a partition plate 20, a refrigerant intake tube 13 and a straightening plate 160, and a shielding plate 180 is provided at a height position between the partition plate 20 and an intake portion 38 of a fixed scroll 30. According to this, refrigerant sucked from the refrigerant intake tube 13 flows toward the partition plate 20 by the straightening plate 160, the refrigerant which flows toward the partition plate 20 collides against the shielding plate 180 before it is sucked by a compression mechanism 170 and therefore, it is possible to prevent refrigerant from coming into contact with the partition plate 20 having high temperature. According to this, the refrigerant is not heated by the partition plate 20, volumetric efficiency is enhanced and high efficiency of the compressor can be realized.
