Abstract
A scroll compressor has a channel formed in a compressor member such as main shaft, frame, orbital scroll member, through which lubricating oil can pass easily from the higher pressure side to the lower pressure side under flow control between sliding surfaces of the compressor members without reduction in the sealing between the higher pressure side and the lower pressure side, whereby injecting sufficient lubricating oil between the scroll members improves both the sealing and the lubricating between the scroll members.
