Zusammenfassung:PURPOSE:To enable to secure the stable flow of lubricating oil to a sliding part, by a method wherein a partition vane for separating an intake space and a compression space from each other is provided, the pressure difference between an inflow hole and an outflow hole for the lubricating oil is reduced, and the cross-sectional area of a passage for the oil is enlarged. CONSTITUTION:The average pressure at the inflow hole 26 for the lubricating oil 16 is higher at a position closer to the partition vane 7 separating an intake space 27 and a compression space 28 from each other. As a result, the pressure difference between the inflow hole 18 and the outflow hole 26 is reduced, and the flow rate of the oil 16 is reduced. Accordingly, the flow rate of the oil 16 can be optimized by appropriately selecting the position of the outflow hole 26 and the flow resistance of the passage 17. In addition, since the difference between the pressure of the oil 16 on the upstream of the passage 17 and that on the downstream of the passage 17 is small, it is unnecessary to excessively increase the flow resistance of the passage 17, the cross-sectional area of the passage 17 can be appropriately enlarged, and a stable flow of the lubricating oil can be secured without generating any clogging even when abraded powder of the sliding part or the like is passed through the passage 17.
