ABSTRACT The present invention is an improved lubrication system for a connecting rod, wrist pin, and piston of a compressor. An oil pump pumps lubricating oil upwardly within an axial bore of the crankshaft, which includes a radial passageway in alignment with the connecting rod. The connecting rod includes ports which direct pulses of oil onto the inner surfaces of the piston. The ports are separated by barrier segments to allow local oil pressure to build between the alignments of the passageway and a port. Thus, pulses of oil are accurately sprayed onto the piston crown without substantially diminishing the lubrication of the journal bearings.
