Abstract
A scroll compressor orbiting scroll bearing lubrication system includes a scroll compressor crankshaft having a lubricating fluid gallery extending therethrough between a first stage orbiting scroll and a second stage orbiting scroll. The first stage employs an orbiting scroll radial bearing and an orbiting scroll hydrodynamic thrust bearing, while the second stage employs an orbiting scroll radial bearing and an orbiting scroll hydrostatic thrust bearing. Lubricating fluid is supplied to the second stage orbiting scroll radial bearing via the lubricating fluid gallery.
