Abstract
A compressor may include a compression mechanism, a driveshaft, and an oil allocation member. The driveshaft drives the compression mechanism and includes a lubricant passage having an inlet and first and second outlets. The first outlet is disposed vertically higher than the inlet and the second outlet is disposed vertically higher than the first outlet. The oil allocation member is disposed within the lubricant passage. The oil allocation member may define first, second and third channels. The first channel extends through a lower axial end of the oil allocation member. The second channel receives a first portion of the lubricant from the first channel. The third channel receives a second portion of the lubricant from the first channel. The first and second portions of the lubricant may be separated from each other at a location that is vertically higher than the first outlet.
