Patent number: 8215933Abstract: A scroll compressor and a refrigerating machine including the same are provided. In the scroll compressor, an oil supply hole formed in an orbiting scroll guides oil from a space between a frame and the orbiting scroll to a space between a fixed scroll and the orbiting scroll, and an oil supply groove formed at the fixed scroll maintains communication with the oil supply hole, thereby rapidly supplying oil to a bearing surface between the fixed scroll and the orbiting scroll before the oil is introduced into a back pressure chamber. This enhances compressor efficiency by effectively preventing frictional losses and refrigerant leakage in such a compressor, and enhances energy efficiency for a refrigerating machine using such a compressor.Type: GrantFiled: June 8, 2009Date of Patent: July 10, 2012Assignee: LG Electronics Inc.Inventors: Cheol-Hwan Kim, Sung-Yong Ahn, Byung-Kil Yoo, Yong-Kyu Choi, Byeong-Chul Lee, Yang-Hee Cho, Se-Heon Choi

Patent number: 8043079Abstract: A hermetic compressor and a refrigeration cycle device having the same are provided. An oil separator is installed either outside or inside of a casing to separate oil from a discharged refrigerant and an oil pump driven by a driving force of a motor is used to recollect the oil separated in the oil separator, whereby the separation between oil and refrigerant can effectively be performed and also a fabricating cost can be reduced. Also, an introduction of the separated refrigerant back into the compressor can be prevented so as to improve a cooling capability of the refrigeration cycle device. In addition, the oil pump is driven by the driving force of the motor, resulting in a simple configuration of the compressor and a reduction of a fabricating cost of the compressor.Type: GrantFiled: July 29, 2008Date of Patent: October 25, 2011Assignee: LG Electronics Inc.Inventors: Byung-Kil Yoo, Nam-Kyu Cho, Dong-Koo Shin, Yang-Hee Cho, Hyo-Keun Park, Cheol Hwan Kim
