PISTON LUBRICATION SYSTEM FOR A RECIPROCATING COMPRESSOR WITH A LINEAR MOTOR

摘要

The present invention provides a piston lubrication system for a reciprocating compressor with a linear motor. The piston lubrication system includes an oil sump defined within a hermetic shell, and a cylinder affixed within the hermetic shell. A radial gap is defined by a piston located within the cylinder. A pump supplies oil from the oil sump to the radial gap via the oil supply duct and oil return duct.
