ABSTRACT:
This invention relates to an oil separator for use in an engine ventilation system for allowing air flow alternately into and out of the engine crankcase without permitting the escape of significant quantities of oil with the air flow. A tube within a tube design forms a compact and effective configuration subjecting the flow to several directional changes and a decrease in velocity effective to cause oil to separate from the flow.
