Abstract
An integrated and compact separator for removing both solid and gaseous contaminants from engine oil. Oil to be cleaned is introduced tangentially into a vortex flow chamber. Oil stripped of gaseous contaminant passes through pores in the outer wall of the vortex flow chamber into a filter system, while gas-rich oil collected near the center of the chamber passes into a gas removal pipe extending in the chamber at its axial center. After solid contaminant is removed by the filter system, the oil is returned to the engine parts to be lubricated.
