Abstract
A first lubricating oil passage and a second lubricating oil passage, extended from a contacting surface between a partition wall and a fixed scroll are formed in the partition wall (middle housing). A recess for communicating the first lubricating oil passage with the second lubricating oil passage is formed on the fixed scroll. Accordingly, the lubricating oil amount between the first lubricating oil passage and the second lubricating oil passage is easily controlled by adjusting the size of the recess.
