1. A scroll-rotation prevention assembly of a scroll compressor, including:
a fixed scroll positioned in the compressor, the fixed scroll having a body, and two blocks extending from the periphery of the body; an orbiting scroll disposed to correspond to the fixed scroll, the orbiting scroll having a main body, and two protrusions extending from the periphery of the main body; and an Oldham ring provided on one side of the orbiting scroll, the Oldham ring having a surface provided with a pair of first troughs and a pair of second troughs, the two protrusions being slidably engaged with the pair of first troughs, respectively, so the orbiting scroll and the Oldham ring are coupled with each other, the two blocks being slidably engaged with the pair of second troughs, respectively, so the fixed scroll and the Oldham ring are coupled with each other, wherein the pair of the first troughs is extended along a first direction, and the positions of the two protrusions are restricted by the pair of the first troughs to make the orbiting scroll to reciprocate in the first direction relative to the Oldham ring, wherein the pair of the second troughs is extended along a second direction, and the positions of the two blocks are restricted by the pair of the second troughs to make the Oldham ring to reciprocate in a second direction relative to the fixed scroll, and wherein the first direction is perpendicular to the second direction. |
