Abstract: A compressor includes: a compression space with an annular shape comprising an inner circumferential surface and an outer circumferential surface; and a discharge opening formed in a direction parallel to a shaft direction of the compressor, to discharge a refrigerant compressed in the compression space, wherein a first portion of a cross-sectional area of the discharge opening overlaps a portion of a cross-sectional area of the compression space, a second portion of the cross-sectional area of the discharge opening 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.

Abstract: A rotary compressor and a method for manufacturing a rotary compressor are provided. The rotary compressor may include a first case in which a stator may be provided, and a second case provided at one side of the first case and to which a compression mechanism may be coupled. The second case may include a first extension to which the compression mechanism may be welded, a step that extends to be stepped from the first extension, and a second extension that extends from the step. The second extension may be welded to the first case.
