Abstract
A scroll compressor lubrication system and a scroll compressor are disclosed. The scroll compressor includes a capacity modulator, a lubricant opening, and a gas diverting passage. The capacity modulator is in fluid communication with compression pockets for selectively unloading gas from the pockets. The lubricant opening is in fluid communication with at least one bearing portion of the scroll compressor. Lubricant from the at least one bearing portion in the scroll compressor flows through the lubricant opening. The gas diverting passage includes an inlet and an outlet. The inlet of the gas diverting passage is in fluid communication with the capacity modulator, and the gas diverting passage extends below the lubricant opening such that gas from the outlet of the gas diverting passage can flow through a travel path of the lubricant that flows through the lubricant opening and entrains at least part of the lubricant to at least one bearing portion for lubrication.
