Abstract
Apparatus for lubricating components in an air compressor having a crankcase for holding oil. The apparatus includes an oil pump located in the crankcase and oil, and a hollow plunger mechanically and hydraulically connected between the oil pump and an eccentric provided on a crankshaft of the air compressor. A filter for filtering the oil held in the crankcase is mounted on a block secured to an external surface of the crankcase. The block mounts the filter on the crankcase and in fluid communication with the pump such that filtered oil is directed to the hollow plunger from the pump after oil is directed into the pump from the filter and after oil is pumped from the crankcase and sent to the filter by the pump.
