Abstract
A compressor oiling system for a horizontal rotary compressor including a pressure plate defining a motor chamber and compressor unit chamber within the compressor each having an oil sump. An opening in the pressure plate allows oil pressurized by discharge pressure from the compressor to pass through an oil pickup passageway leading from the sump portion of the compressor unit chamber to the outboard bearing of the actual compressor unit. During compressor operation, discharge gases create a pressure differential across the pressure plate allowing the oil level to raise within the compressor unit chamber to the level of the crankshaft thereby lubricating the crankshaft bearings.
