    Abstract: A scroll compressor is provided, in which at least one bypass hole that bypass a portion of a refrigerant before the refrigerant is discharged through a discharge hole is formed at a position where a bypass section that bypasses the refrigerant through the at least one bypass hole overlaps a discharge section that discharges the refrigerant through the discharge hole. The at least one bypass hole is formed at a position where a wrap volume ratio (Vs/Vd), which is a ratio of a suction volume (Vs) with respect to a discharge volume (Vd) in a compression chamber, is within the range of about 1.8˜2.2. With this configuration, over-compression of refrigerant may be prevented in a low speed driving mode, and efficiency of the compressor may be enhanced in the low speed driving mode and under a low load condition.

    Abstract: In a scroll compressor, a pass hole is formed at a position overlapping with a discharge sector of a discharge hole, where a sector for passing a refrigerant through the pass hole is overlapped with a sector for discharging the refrigerant through a discharge hole. This may prevent over-compression of a refrigerant when the scroll compressor is driven at a low speed. This may enhance efficiency of the scroll compressor in a low speed driving mode and under a low load condition.

    Abstract: A compressor having a lower frame and a method of manufacturing the same are disclosed. The compressor may include a cylindrical shell, a rotational shaft rotatably mounted in the cylindrical shell, a rotor and a stator that rotates the rotational shaft, a compression device driven by the rotational shaft, a lower bearing configured to rotatably support one side of the rotational shaft, a lower frame configured to support the lower bearing, the lower frame being configured to be press-fitted into a lower end portion of the cylindrical shell, and a base configured to seal the lower end portion of the cylindrical shell. The lower frame may include a main body configured to be press-fitted onto an inner circumferential surface of the cylindrical shell and a flange that extends from the main body, the flange being configured to limit a press-fit depth by contacting the lower end portion of the cylindrical shell.
