Abstract

A compressor includes a compression mechanism and a driveshaft that drives the compression mechanism. The driveshaft may include a first axially extending passage, a second axially extending passage, and a lubricant distribution passage. The first and second axially extending passages may be radially offset from each other and may intersect each other at an overlap region. The first and second axially extending passages are in fluid communication with each other at the overlap region. The lubricant distribution passage may extend from the first axially extending passage through an outer diametrical surface of the driveshaft. The lubricant distribution passage may be disposed at a first axial distance from a first axial end of the driveshaft. A first axial end of the overlap region may be disposed at a second axial distance from the first axial end of the driveshaft. The first axial distance may be greater than the second axial distance.
