Patent number: 9181947Abstract: A compressor is provided in which a rotary member suspended on a stationary member is rotated to compress a refrigerant. As the rotary member is suspended on a first stationary member and rotatably supported on a second stationary member spaced apart from the first stationary member, components can be easily centered and assembled with structural stability. In addition, oil stored in a hermetic container is supplied to a lubrication passage provided between the rotary member and the stationary member. This reduces friction loss between the components and achieves operational reliability. Moreover, the oil is easily introduced into a vane mounting hole in which a vane is linearly reciprocated. This reduces friction and abrasion of the vane and improves the operational reliability.Type: GrantFiled: December 2, 2009Date of Patent: November 10, 2015Assignee: LG ELECTRONICS INC.Inventors: Kang-Wook Lee, Jin-Ung Shin, Geun-Hyung Lee, Seoung-Min Kang
