Abstract
A lubricating system for an internal combustion engine is provided wherein oil flows from a compressor oil drain port to a region of the engine which is to be lubricated. The source of lubricating fluid, such as the compressor, is transmitted through a first conduit between the compressor and a lubricant supply region of the engine block. The lubricant supply region is located between a first seal region, or labyrinth seal, and a region to be lubricated which can be a center main bearing. The region to be lubricated is located between the lubricant supply region and a first lower pressure region of the engine, such as the crankcase region associated with one of the cylinders of the engine. A check valve is used to resist flow of the lubricating fluid in a direction from the lubricant supply region to the lubricating fluid source.
