Abstract: A scroll compressor is provided that may include a casing having a sealed inner space; a drive motor provided in the inner space of the casing to generate a rotational force; a rotational shaft rotatably coupled to the drive motor; an orbiting scroll formed of an aluminum material, and coupled to the rotational shaft to perform an orbiting movement; a fixed scroll coupled to the orbiting scroll to form a compression space; and an Oldham ring coupled to the orbiting scroll, and formed of a sintered metal. With this structure, it may be possible to prevent the Oldham ring from being worn out due to contact with the orbiting scroll. Further, a weight loss portion or wear-resistant coating layer may be formed on a portion of the Oldham ring, thereby suppressing or preventing vibration noise of the scroll compressor from being increased due to a weight increase of the Oldham ring.

Abstract translation: 提供一种涡旋压缩机，其可以包括具有密封的内部空间的壳体; 设置在所述壳体的内部空间中以产生旋转力的驱动马达; 可旋转地联接到所述驱动电动机的旋转轴; 由铝材料形成的旋转涡卷，并且联接到所述旋转轴以执行轨道运动; 固定涡旋盘，其联接到所述绕动涡旋件以形成压缩空间; 以及联接到绕动涡旋件的十字环，并且由烧结金属形成。 利用这种结构，可以防止由于与绕动涡盘接触而造成奥德姆环磨损。 此外，可以在奥德姆环的一部分上形成减重部分或耐磨涂层，从而抑制或防止由于奥德姆环的重量增加涡旋压缩机的振动噪声增加。

Abstract: A fluid compressor includes a case, a fixed scroll, an orbiting scroll, a motor, and at least one anti-rotation unit. The case is configured to form an external appearance thereof. The fixed scroll is fixed in the case. The orbiting scroll is engaged with the fixed scroll at one side of the fixed scroll, and performs partitioning of a compression chamber. The motor provides the orbiting scroll with drive power. The anti-rotation unit is coupled to a side surface of the orbiting scroll so as to prevent rotation of the orbiting scroll.
