Abstract

Abstract A device for the continuous reconditioning of lubricating oil for use with an internal combustion engine, including a closed casing having an oil inlet line and an oil return line at a first lower end, an annular oil filter within the casing for mechanical filtration of oil, a vaporization plate having a tiered concave frustoconical top surface and peripheral capillary flow passages for conducting filtered oil to the top face of the plate, a central return conduit opening into the center of the plate and connected with the return line from the casing for flowing processed oil back to the oil pan of the engine, an annular heater within the casing above the vaporization plate for heating oil cascading down the plate surface to drive off entrained water and the like, and a vapor discharge line connected with a check valve through the top of the casing to exhaust separated vapor contaminants and prevent liquid over-flow. Oil is forced from the engine oil pump upwardly through the filter to the top of the vaporization plate where the oil cascades downwardly in a heated atmosphere returning through the central conduit to the oil return line from the bottom of the casing while vaporized contaminants are discharged from the housing through the exhaust line at the top of the housing. The returning oil is directed back to the engine oil pan and the exhausted vapors are introduced into the engine intake.
