    • A scroll compressor includes first and second scroll bodies having respective bases and respective scroll ribs that project from the respective bases such that the scroll ribs mutually engage. The second scroll body is movable relative to the first scroll body for compressing fluid. A drive shaft has a longitudinal axis and an eccentric drive pin configured to engage a drive hub on the second scroll body. A counterweight has a hub portion, and a perimeter portion positioned radially outward from the hub portion. A radial axis divides the counterweight into a first and second regions. The mass of the hub portion in the first region being roughly equal to the mass of the hub portion in the second region, and the mass in the perimeter portion being distributed between the first and second regions such that the center of mass of the counterweight is located along the radial axis.
    • 涡旋压缩机包括具有各自的基部的第一涡旋体和第二涡旋体,以及从各个基部突出的各自的涡旋肋,使得涡旋肋相互接合。 第二涡旋体相对于第一涡旋体可移动以压缩流体。 驱动轴具有纵向轴线和偏心驱动销,所述偏心驱动销构造成与第二涡旋体上的驱动轮毂接合。 配重具有轮毂部分和从轮毂部分径向向外定位的周边部分。 径向轴将配重分成第一和第二区域。 第一区域中的毂部的质量大体上等于第二区域中的毂部的质量,并且周边部分中的质量分布在第一和第二区域之间,使得配重的质心为 沿着径向轴定位。
