Abstract
Abstract A receptacle containing an electric heater has an inlet for receiving lubricating oil from an internal combustion engine, a vapor discharge vent for returning vapors to the engine, and an oil outlet for returning oil to the engine. Encircling the heater and heated by it is a hollow non-metallic vaporizing unit. A tube in the receptacle is connected to the oil inlet and forms a perforated loop around the upper end of the vaporizing unit for delivering oil to it to maintain a downwardly flowing film of oil on the outside of the vaporizing unit so that water and hydrocarbons will be vaporized from the oil and be drawn out through the vent.

Claim 1
Independent Claim
177 words
In an internal combustion engine oil refining device in which a receptacle containing an elongated electric heater has an oil inlet and a vapOr discharge vent in its upper part and an oil oulet in its bottom, the vent being adapted to be connected with the inside of an internal combustion engine; a hollow non-metallic vaporizing unit encircling said heater for heating thereby, said vaporizing unit being an upwardly tapered flask provided with a hole in its bottom, said heater extending downwardly from the top of the receptacle and through said flask and hole, means mounted on the projecting lower end of said heater supporting the flask, and a tube in the receptacle connected to said oil inlet and forming a loop around the upper end portion of said flask provided with perforations for delivering oil thereto to maintain a downwardly flowing film of oil on the outer surface of said flask, said outer surface being characterized by draining free of oil whenever delivery of oil to it stops, whereby oil does not carbonize on said surface.
