A horizontal scroll-type compressor utilizes the pressure differential between the discharge pressure and the suction pressure to route lubricant from the discharge chamber to the components within the intake chamber. The compressor may utilize a lubricant separator within the discharge chamber to separate the working fluid from the lubricant prior to the working fluid exiting the compressor. The compressor may use an internal passageway that extends from the discharge chamber to a position adjacent the crankshaft to provide lubricant to the internal lubricant passage within the crankshaft.

What is claimed is: 1. A compressor comprising: a shell; a discharge chamber defined within said shell and operating at a first pressure; an intake chamber defined within said shell and operating at a second pressure; a compression mechanism disposed within said intake chamber configured to move a fluid from said intake chamber to said discharge chamber; a crankshaft disposed within said intake chamber and drivingly engaged with said compression mechanism; a partition within said shell separating said discharge chamber from said intake chamber; two bearing housings disposed within said intake chamber and each rotatably supporting different portions of said crankshaft, a first one of said bearing housings supporting a proximal end portion of said crankshaft adjacent said compression mechanism, and a second one of said bearing housings supporting a distal end portion of said crankshaft; and a closed lubricant passageway contained in said shell and having first and second ends such that lubricant in said lubricant passageway only enters and exits said lubricant passageway through said first and second ends, said lubricant passageway extending from said discharge chamber into said second bearing housing with said first end disposed in said discharge chamber and said second end disposed in said second bearing housing, said lubricant passageway thereby providing direct fluid communication between said discharge chamber and said second bearing housing with lubricant therein flowing from said discharge chamber directly to said second bearing housing, and said lubricant passageway being exterior to said compression mechanism and passing through said partition. 2. The compressor of claim 1, wherein said compression mechanism includes first and second scroll members and said lubricant passageway is exterior to said scroll members. 3. The compressor of claim 1, wherein said compressor is a horizontal compressor. 4. The compressor of claim 1, wherein said partition is a component separate and discrete from said compression mechanism. 5. The compressor of claim 1, further comprising a motor disposed within said intake chamber, said motor drivingly engaged with said crankshaft. 6. The compressor of claim 1, further comprising a lubricant separator located within said discharge chamber and in communication with an outlet of said compression mechanism. 7. The compressor of claim 1, further comprising a filter member in communication with said lubricant passageway, said filter located upstream of said lubricant passageway. 8. The compressor of claim 1, wherein said lubricant passageway is at least partially formed by a tube member and a fitting. 9. The compressor of claim 1, wherein said shell is a hermetic shell. 10. A compressor comprising: a shell; a discharge chamber defined within said shell and operating at a discharge pressure; an intake chamber defined within said shell and operating at a suction pressure less than said discharge pressure; a compression mechanism disposed within said intake chamber configured to move a fluid from said intake chamber at said suction pressure to said discharge chamber at said discharge pressure; a partition within said shell separating said discharge chamber from said intake chamber; a crankshaft having opposite first and second crankshaft ends and disposed within said intake chamber, said second end drivingly engaged with said compression mechanism, and said crankshaft extending substantially horizontally within said shell; a bearing housing disposed within said intake chamber and rotatably supporting a portion of said crankshaft; and a first lubricant passageway extending from said discharge chamber into said bearing housing, said first lubricant passageway having first and second lubricant passageway ends such that lubricant in said first lubricant passageway enter and exits said first lubricant passageway through said first and second lubricant passageway ends, said first lubricant passageway end is disposed in said discharge chamber and said second lubricant passageway end is disposed in said bearing housing, said first lubricant passageway providing direct fluid communication between said discharge chamber and said bearing housing, and said first lubricant passageway passes through said partition, wherein said crankshaft includes a second lubricant passageway extending therein from said first crankshaft end to said second crankshaft end, said crankshaft includes at least one opening extending radially inwardly through an exterior portion thereof adjacent said first crankshaft end and in communication with said second lubricant passageway in said crankshaft, said lubricant at said discharge pressure flows from said discharge chamber and through said intake chamber prior to flowing into said second lubricant passageway in said crankshaft, said first lubricant passageway directs said lubricant at said discharge pressure into said second lubricant passageway in said crankshaft through said at least one opening, and said lubricant flows through said second lubricant passageway and out said second crankshaft end as a result of a pressure differential between said discharge pressure and said suction pressure. 11. The compressor of claim 10, wherein said at least one radially extending opening is located in a non-load bearing section of said crankshaft. 12. The compressor of claim 10, wherein said compression mechanism includes first and second scroll members and said lubricant passageway is exterior to said scroll members. 13. The compressor of claim 10, wherein said compressor is a horizontal compressor. 14. The compressor of claim 10, wherein said partition is a component separate and discrete from said compression mechanism. 15. The compressor of claim 10, further comprising a motor disposed within said intake chamber, said motor drivingly engaged with said crankshaft. 16. The compressor of claim 10, further comprising a lubricant separator located within said discharge chamber and in communication with an outlet of said compression mechanism. 17. The compressor of claim 10, further comprising a filter member in communication with said lubricant passageway, said filter located upstream of said lubricant passageway. 18. The compressor of claim 10, wherein said lubricant passageway is at least partially formed by a tube member and a fitting. 19. The compressor of claim 10, wherein said shell is a hermetic shell. 20. The compressor of claim 10, wherein lubricant in said first lubricant passageway only enters and exits said first lubricant passageway through said first and second lubricant passageway ends.
