ABSTRACT:
An oil separator for reducing oil carryover from the vent port of the crankcase of an internal combustion engine, such as a diesel engine is provided. The separator includes a cylindrical housing filled with a filtration material and having both an inlet and an outlet in its upper portion and a downwardly disposed, frustro-conical wall that defines an annular chamber between its outer surface and the inner walls of the housing. The annular chamber defines a helical flow path through the filtration material in the housing for a stream of oil-laden air admitted through the inlet of the housing. Oil droplets are removed from the stream of air as it moves through the helical path both by impingement against the filtration material, and the by centrifugal impingement against the inner walls of the housing. At the end of the helical path, the stream of air is directed along a hairpin turn through an opening in the frustro-conical wall and from thence into a double-back path before exiting the housing, thereby removing still more entrained oil droplets. The resulting filtered stream of air may be directed into the engine draft tube or the air filter by means of a pipe. The separator also includes an oil drain conduit for conducting liquid oil collected by the filtration material into the oil pan of the engine at a level lower than the operating level of the oil within the pan for uninhibited drainage.
