PROBLEM TO BE SOLVED: To supply lubricant agent in a high efficient manner to a bearing for rotatably supporting a drive bush against a revolving scroll.SOLUTION: This invention comprises: a revolving scroll; a drive bushing rotatably supported at a revolving scroll through a bearing; and a balance weight 23 arranged between a refrigerant supply chamber to which lubricant agent mixing refrigerant is supplied and the bearing. The revolving scroll is revolved in respect to a fixed scroll while the drive bushing 21 is rotated. A surface 26 of the balance weight 23 facing against the refrigerant supply chamber is formed with a lubricant supply port 28 formed near the bearing and a lubricant catching flow passage 29 connecting the refrigerant supply chamber to the lubricant supply port 28. Such a scroll compressor enables the lubricant separated by a centrifugal force from the lubricant agent mixed refrigerant at the lubricant agent catching flow passage 29 to be supplied to the bearing through the lubricant agent supply port 28 and so the lubricant agent can be supplied to the bearing in a high efficient manner.SELECTED DRAWING: Figure 2 |
