ABSTRACT:
An oil separator device for use in a crankcase ventilation system of an internal combustion engine. The device comprises a cannister having an internal baffle member and partition means defining therewith an oil laden fume inlet chamber, an oil separating chamber and a fume outlet chamber. Oil laden fumes enter the fume inlet chamber where they are directed by the baffle member to a first 180.degree. volute section of the oil separating chamber and then to a second 180.degree. volute section having a smaller radius of curvature than the first section to thereby produce a vortex region adjacent to the center of the second volute section. Gaseous fluid with oil removed flows upwardly out of the oil separating chamber into the fume outlet chamber through a flue aperture in the partition at a location above the vortex region while separated oil is returned to the engine lubrication system through a drain aperture in the bottom of the cannister.
