Abstract
A scroll compressor includes a casing having a cylindrical barrel and lid, a compression mechanism having fixed and movable scrolls, and a suction passage that sends a fluid into a compression chamber. The fixed scroll includes a fixed-side end plate, a fixed-side wrap standing upright on the fixed-side end plate, and a suction hole. The suction hole is capable of communicating with the compression chamber. The suction passage includes an insertion pipe portion inserted into a through hole of the lid, and an in-plate passage formed in the fixed-side end plate and having an outflow opening opened toward the suction hole. A center of the through hole is closer to an axis of the barrel than a center of the outflow opening of the in-plate passage. An entirety of the suction passage is positioned radially outward of a portion, of the through hole, closest to the axis of the barrel.
