Claims (1)

[Claims for Utility Model Registration] (1) A fixed scroll and an oscillating scroll each having a volute and forming a compression chamber between the volutes by meshing the volutes with each other, and a crank that drives the oscillating scroll. In a scroll compressor with a shaft, the compression chamber has a discharge port near the center of the fixed scroll's swirl, and when the pressure in the innermost compression chamber reaches a set pressure near the center of the swirl of the oscillating scroll, it opens to discharge the fluid in the compression chamber. A scroll compressor characterized by being equipped with a relief valve mechanism. (2) The scroll compressor according to claim 1, wherein the fluid discharge port of the relief valve mechanism of the oscillating scroll is provided outside the crankshaft bearing of the oscillating scroll.
