Abstract
In a rotary compressor, a lower end plate cover is formed in a flat plate shape, a lower discharge chamber concave portion is formed in a lower end plate to overlap a lower discharge hole side of a lower discharge valve accommodation concave portion, and the lower discharge chamber concave portion is formed in a fan-like range between a diametrical line passing through a center of a sub-bearing unit and a midpoint of a line segment connecting a center of the lower discharge hole and a center of a lower rivet to each other and a diametrical line opened by a pitch angle 90° in a direction of the lower discharge hole about the center of the sub-bearing unit. At least a portion of a refrigerant path hole overlaps the lower discharge chamber concave portion and is disposed at a position communicating with the lower discharge chamber concave portion.
