Scroll compressor

A scroll compressor comprising:

• a compression mechanism including a fixed scroll and an orbiting scroll, the fixed scroll having a fixed scroll thrust sliding surface, and the orbiting scroll having an end plate with an orbiting scroll thrust sliding surface pressed against and in sliding contact with the fixed scroll thrust sliding surface;
• a drive shaft engaging with the orbiting scroll;
• and
• a casing housing the compression mechanism and the drive shaft,
• the scroll compressor being configured to cause the compression mechanism to compress a fluid and discharge the fluid into the casing,
• one of the orbiting scroll thrust sliding surface or the fixed scroll thrust sliding surface being provided with an oil groove into which lubricating oil flows,
• a bearing oil supply passage provided inside the drive shaft does not communicate with the oil groove and is used to supply the lubricating oil in an oil reservoir in the casing to a bearing of the drive shaft,
• a sliding surface oil supply passage being used to supply the lubricating oil in the oil reservoir to the oil groove, and
• the sliding surface oil supply passage having a sliding surface main passage provided inside the drive shaft,
• wherein the compression mechanism has a housing with the drive shaft inserted therein, and
• the sliding surface oil supply passage further includes
• a first connecting passage provided inside the fixed scroll and communicating with the oil groove,
• a second connecting passage provided inside the housing and communicating with the first connecting passage, and
• a third connecting passage provided inside the drive shaft and communicating with the second connecting passage and the sliding surface main passage.
