A compressor includes: a compression space (S) with an annular shape comprising an inner circumferential surface and an outer circumferential surface; and a discharge opening (111) communicated with the compression space (S), to discharge a refrigerant compressed in the compression space, wherein a first portion (A B ) of a cross-sectional area of the discharge opening (111) overlaps a portion of a cross-sectional area of the compression space, a second portion (A C ) of the cross-sectional area of the discharge opening (111) does not overlap the cross-sectional area of the discharge opening, and the ratio of the non-overlapping second portion of the cross-sectional area of the discharge opening to the entire cross-sectional area of the discharge opening is 0.1 or less. With such a configuration, a dead volume generated in the compression space can be reduced, and thus compressor efficiency can be enhanced. |
