Abstract
An oil distribution system for lubricating bearings in a scroll compressor. The system includes an oil collector cup attached to the lower surface of a swing link. Oil pumped through an internal passage in a rotating drive shaft is retained in the collector cup when the compressor stops, so that it is immediately available to lubricate adjacent bearings upon restart of the machine. Also disclosed in two embodiments are means for distributing and properly allocating the flow of oil between a thrust bearing and a swing link bearing.
