    • A ball coupling constituting a rotation preventing mechanism (77) includes a first annular race section (59, 79) having a thrust ball transfer surface formed on one surface thereof, a second annular race section (61, 81) having a ball transfer surface formed on one surface thereof confronting the one surface of the first race section and thrust balls (67) interposed between the first and second race sections (79, 81). At least one of the first and second race sections has a cross sectional shape such that the central portion of the other surface (87) thereof confronting the one surface is a recessed groove (89). A scroll type compressor includes the rotation preventing mechanism on the back surface of a movable scroll member.
    • 构成旋转防止机构(77)的球形联轴器包括在其一个表面上形成有推力球转移面的第一环形圈部(59,79),形成有球转移面的第二环形圈部(61,81) 在其面对第一座圈部分的一个表面的一个表面上以及置于第一和第二座圈部分(79,81)之间的推力球(67)。 第一和第二座圈中的至少一个具有横截面形状,使得面对该一个表面的另一个表面(87)的中心部分是凹槽(89)。 涡旋式压缩机包括在可动涡旋件的后表面上的防旋转机构。

    • A scroll-type compressor includes a fixed and an orbiting scroll each having an end plate and a spiral element on the end plate and interfits with each other. A first transition line at a widened-starting portion of the spiral element between an interior wall and a tip surface comprises a first upper arc connecting to an upper, interior involute wall starting point and a second upper arc connecting to an upper, exterior involute wall starting point and a straight line. A second transition line at the widened-starting portion between the interior wall and a base surface comprises a first lower arc connecting to a lower, interior involute wall starting point and a second lower arc connecting a lower, exterior involute wall starting point and a straight line.
    • 一种涡旋式压缩机包括一个固定的和一个绕动的涡旋盘,它们在端板上具有一个端板和一个螺旋形元件,并且彼此相互配合。 在内壁和尖端表面之间的螺旋形元件的加宽起始部分处的第一过渡线包括连接到上部内部渐开线壁起点的第一上部弧线和连接到上部外部渐开线壁的第二上部弧线 起点和直线。 在内壁和基面之间的加宽起始部分处的第二过渡线包括连接到下内部渐开线壁起点的第一下弧线和连接下外部渐开线壁起点的第二下弧线和直线 线。
