    Abstract: A scroll compressor includes a fixed scroll; an orbiting scroll that interfaces the fixed scroll; an Oldham ring that interfaces the orbiting scroll and has a pre-unbalanced force profile; and a motor shaft that interfaces the Oldham ring. The Oldham ring pre-unbalanced force profile is in the form of a sine wave. One of the shaft and the orbiting scroll has an imbalance weight portion; wherein the imbalance weight portion provides a weighted force profile that is 180° opposite of the pre-unbalanced force profile of the Oldham ring and produces in the Oldham ring a post-unbalanced force profile that is substantially a flat line.

    Abstract translation: 涡旋压缩机包括固定涡旋件; 与固定涡旋件相接的绕动涡卷; 一个与轨道运行的涡旋盘相接并具有预不平衡力分布的奥德姆环; 以及与奥德姆环接合的电机轴。 奥德姆环预先不平衡力分布呈正弦波形。 轴和动涡旋盘中的一个具有不平衡重量部分; 其中所述不平衡重量部分提供与所述十字形环的预不平衡力分布相反180°的加权力分布，并且在所述十字形环中产生基本上为平坦线的后不平衡力分布。

    Abstract: A compressor comprising: a first compressor wheel comprising a first chamber configured to retain a medium, a first impeller disposed within the first chamber and configured to revolve around a longitudinal axis of the compressor, and a first diffuser coupled to the first chamber; and a second compressor wheel comprising a second chamber disposed radially outwards of the first chamber relative to the longitudinal axis, wherein the second chamber is configured to receive the outputted medium from the first chamber, a second impeller disposed within the second chamber and configured to revolve around the longitudinal axis of the compressor within the second chamber, and a second diffuser coupled to the second chamber, wherein each blade of the first impeller defines a fillet extending along an outer edge of the blade, and wherein a width of the fillet along a surface of the respective blade varies along the longitudinal axis.
