A spiral body 22 is attached to the casing 1 and the end plates 21 and 31.
, 32, respectively, are installed internally in a combination of opposing fixed and movable scrolls 2 and 3, respectively, and two systems of compression chambers A and B are formed between the spiral bodies 22 and 32. A pair that compresses suction fluid in B and discharges the compressed fluid from the discharge hole 12 via the discharge valve 13, and opens the compression chambers A and B in the middle of the compression stroke to the compression chambers A and B, respectively. In a scroll compressor configured to communicate with the suction side through bypass holes 6A, 6B to perform capacity control, a pair of bypass passages 8A, 8B that communicate the bypass holes 6A, 6B with the suction side, respectively; An unloader valve block 60 including a pair of unloader pistons 9A and 9B for opening and closing the bypass passages 8A and 8B is formed in the center of the valve block 60, covering the discharge valve 13 and discharging the air from the discharge hole 12. A scroll compressor characterized by integrally forming a muffler 61 for silencing fluid discharged.
