A compressor and oil separation device therefore are provided. The oil separation device is integrated with a compressor and includes a first case having a refrigerant inlet into which a refrigerant mixed with oil is sucked and an oil recollecting member through which oil separated from the refrigerant flows, and a second case positioned outside of the first case and having a refrigerant outlet through which refrigerant separated from an oil is discharged. With this constructions, a pipe connecting the compressor and a separate oil separation device is not required, thereby reducing fabrication costs and facilitating installation.

What is claimed is: 1. A compressor, comprising: a first case; a compression device having a compression chamber within the first case configured to receive, compress, and discharge a refrigerant, wherein the compression chamber is in direct connection with a suction pipe of the compressor; and an oil separation device that surrounds the first case configured to receive the refrigerant discharged from the compression device and separate oil therefrom, wherein the oil separation device comprises a second case configured to surround at least a portion of the first case to form an oil separation space therebetween, wherein the refrigerant is received into the oil separation space and circulates along the oil separation space to separate oil from the refrigerant, and wherein an input hole is formed in the first case through which the refrigerant discharged from the compression device is received into the oil separation space, and a discharge hole is formed in the second case that is connected with a discharge pipe of the compressor through which the refrigerant is discharged from the compressor. 2. The compressor of claim 1, wherein the second case comprises an arc shaped portion that surrounds an outer surface of a portion of the first case. 3. The compressor of claim 2, further comprising a member that forces the refrigerant to circulate along the oil separation space. 4. The compressor of claim 1, wherein the oil separation device further comprises an oil outlet hole formed in the first case. 5. A scroll compressor comprising the compressor of claim 1. 6. The compressor of claim 3, wherein the member is configured in a longitudinal direction of the first case and the second case, and entirely divides the oil separating space between the input hole and the discharge hole.
