Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2015/093504
Kind Code:
A1
Abstract:
A compressor provided with a centrifugal oil separator, wherein the oil separator of the compressor is reduced in size by improving the oil separation performance of the oil separator. Even when the oil separator is reduced in size, a refrigerant inlet channel can be formed without interference between a machining drill and a separating pipe when the refrigerant inlet channel is drilled, and the refrigerant inlet channel is smoothly joined to the inner peripheral surface of a separation chamber, thereby further improving oil separation performance. Furthermore, large clearance is ensured in the region faced by the opening of the refrigerant inlet channel. [Solution] A compressor provided with an oil separator (14) having a separation chamber (22), a separation pipe (23) accommodated in the separation chamber (22), and a refrigerant inlet channel (21) communicating a discharge chamber (11) and the separation chamber (22), wherein the axial center (O) of the separation chamber (22) and the axial center (O') of the separation pipe (23) are misaligned.
