Abstract
A scroll compressor includes a casing, a compression mechanism accommodated within the casing, a motor arranged to rotatably drive the crankshaft, an oil feed pump arranged to feed lubricating oil upward, a lower oil reservoir disposed in a space below the oil feed pump to hold lubricating oil, an oil feed path and an oil retention space. The compression mechanism has a stationary scroll and a moveable scroll forming a compression chamber. The crankshaft is linked to the moveable scroll. The oil feed passage is formed so as to extend in an axial direction within an interior of the crankshaft and communicates at a lower end with a discharge side of the oil feed pump. The oil retention space is formed so as to extend in an axial direction within the interior of the crankshaft separately from the oil feed passage and communicates with the oil feed passage.
