Abstract:
1. A compressor comprising: a shell; a compression mechanism supported within said shell; a drive shaft engaged with said compression mechanism and defining first and second passages extending axially within said drive shaft and a third passage extending radially through an outer circumferential surface of said drive shaft and in communication with said first and second passages, said drive shaft defining an axially extending wall separating said first and second passages, said drive shaft including a supply passage extending axially through a first axial end of said drive shaft, said first and second passages fluidly communicating with said supply passage and extending axially from said supply passage; and a motor including a rotor fixed to said drive shaft and a stator supported within said shell, said stator including an upper stator winding and a lower stator winding, said third passage adapted to fling oil onto said upper stator winding during compressor operation to cool said stator, wherein said third passage is aligned in an axial direction with a portion of said upper stator winding, and wherein said oil is travelling radially outwardly when said oil contacts said upper stator winding.
