Patent abstract
Lubrication of bearing surfaces in a scroll compressor is enhanced by a vent arrangement which makes use of increased centrifugal force, achieved by locating the outlet of the vent arrangement radially outside of the nominal circumference of the compressor's drive shaft, to both remove refrigerant gas from compressor locations where such gas can inhibit the flow and delivery of lubricant to such surfaces and to increase the lift of lubricant out of the compressor's lubricant sump. Oil retained in the upper surface of the compressor drive shaft is made immediately available for bearing lubrication upon compressor start-up to further enhance compressor lubrication.
