摘要： A scroll compressor includes a scroll compression unit having a fixed scroll and an orbiting scroll a drive shaft configured to drive the orbiting scroll in an orbital movement, and a support frame including a bearing configured to guide in rotation a guided portion of the drive shaft. The scroll compressor also includes an anti-rotation device including a pair of first engaging elements slidably engaged with a pair of complementary engaging elements on the support frame; and a lubrication system to lubricate at least partially the first engaging elements. The lubrication system includes a lubrication channel and hole on the drive shaft; the hole is fluidly connected to the channel and emerges in an outer wall of the guided portion. The system further includes an oil lubrication passage on the support frame, which includes an oil inlet aperture emerging in a receiving chamber, and an oil outlet aperture configured to supply with oil at least one of the first engaging elements.
