Abstract

An oil lubrication circuit is provided for an internal combustion engine in which first and second paths are located within a central bore of a camshaft. Liquid lubricant is directed from a gerotor pump to an oil filter and back toward numerous lubrication points of a crankshaft by utilizing the first and second paths which flow in opposite directions and which are both concentric with a central axis of rotation of the camshaft.
