    • A scroll compressor includes a fixed scroll having a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to define a first compression chamber between an inner surface of the fixed wrap and an outer surface of the orbiting wrap, and to define a second compression chamber between an inner surface of the orbiting wrap and an outer surface of the fixed wrap. A rotation shaft is provided with an eccentric portion at one end thereof to drive the orbiting scroll. A protruding portion protrudes inwardly from an inner end of the fixed wrap, and contacts the orbiting wrap. A distance between a center of the eccentric portion and a tangent line at a contact point between the protruding portion and the orbiting wrap at an end of the first compression chamber is smaller than a radius of the eccentric portion.
    • 涡旋压缩机包括具有固定涡卷的固定涡旋盘和具有与固定涡旋件接合的绕动涡卷的绕动涡旋盘,以在固定涡卷的内表面和绕动涡卷的外表面之间限定第一压缩室, 在所述绕动涡卷的内表面和所述固定涡卷的外表面之间限定第二压缩室。 旋转轴在其一端设置有偏心部,以驱动绕动涡旋件。 突出部分从固定包装的内端向内突出,并且与绕动包裹物接触。 所述偏心部的中心与所述突出部与所述第一压缩室的端部的所述绕线卷绕部之间的接触点处的切线之间的距离小于所述偏心部的半径。
