Patent number: 7249936Abstract: A dual capacity compressor, which can maintain a fixed eccentricity and stable operation, even when the compressor is rotated in both the regular and reverse directions in order to provide multiple compression capacities, is provided. This dual capacity compressor implements an improved key member and associated key member fitting parts to inhibit relative motion of the crank pin and the eccentric sleeve during operation, so as to reduce or eliminate a destabilizing effect due to centrifugal forces on the eccentric sleeve and external forces applied through the connecting rod.Type: GrantFiled: May 18, 2004Date of Patent: July 31, 2007Assignee: LG Electronics Inc.Inventors: Young Ju Bae, Jong Bong Kim, Chul Gi Roh, Jae Sung Sim, Dal Soo Kang, Min Young Seo, Hyun Kim, Kyoung Jun Park, Kee Joo Kim, Hee Hyun Kim

Patent number: 7100743Abstract: A crankshaft in a dual capacity compressor is disclosed, which causes oil contained in a lower portion of the compressor to flow up to an upper portion thereof with respect to all the rotational directions of a motor. A crank shaft (100) includes a driving shaft (110) inserted into a reversible motor (21, 22) for rotating along with the motor (21, 22), a balance weight (120) formed in a top portion of the driving shaft (110) for preventing vibration during rotation from occurring, a crank pin (130) formed on an upper surface of the balance weight (120) to be eccentric from the center of the driving shaft (110), and a regular/reverse oil path (140) formed along the balance weight (120) and the crank pin (130) for moving oil for forward rotation and reverse rotation of the motor respectively. The crankshaft serves to stably lubricate each driving part of the dual capacity compressor regardless of rotation direction.Type: GrantFiled: December 17, 2001Date of Patent: September 5, 2006Assignee: LG Electronics Inc.Inventors: Kyoung Jun Park, Kee Joo Kim, Hee Hyun Kim, Jong Bong Kim, Young Joo Bae, Cheol Ki No, Jai Seong Sim, Min Young Seo, Hyeon Kim, Dal Soo Kang
