Beschreibung
Zusammenfassung:	A scroll compressor, comprising: an orbiting scroll (7), a fixed scroll (8), an anti-rotation mechanism (10), a support (9), a crankshaft (12) provided with an eccentric pin portion (12c) which is eccentric with respect to an axis, the crankshaft (12) being provided with a flange portion (12d) at a lower portion of the eccentric pin portion (12c), the flange portion (12d) being larger than the diameter of the eccentric pin portion (12c), a counterweight (21) mounted on the flange portion (12d), a sealing component (25) performing sealing between the orbiting scroll (7) and the flange portion (12d), and a thrust bearing (26) arranged between the support (9) and the flange portion (12d). The scroll compressor reduces the amount of oil flowing into a back pressure chamber, thereby improving the performance of the scroll compressor.
