US 4,006,084 A · Oil reclaiming device

Abstract

A device for use with an internal combustion engine for reconditioning oil by removal of solid and liquid contaminants including a housing having an oil inlet at one end and an oil outlet at an opposite end and containing a filter for removal of solid matter, a preheating chamber, a vaporization chamber for removal of liquid contaminants, and a convex conical vaporization plate separating and defining the roof of the preheating chamber and the floor of the vaporization chamber. The vaporization plate has a plurality of concentric tiers. The upper innermost tier of the vaporization plate has a plurality of capillaries each of which opens to the top planar surface of the tier through an expansion cup defined within an upwardly protruding lip. An electrical resistance heater is supported above the vaporization chamber for heating the vaporization chamber, the vaporization plate, and the preheating chamber. A vent for vaporized contaminants extends through the upper end of the housing. The device is connected in the oil circulation system of the engine with oil being pumped through the inlet into the filter for removal of solid contaminants. The oil and liquid contaminants flow from the filter into the preheating chamber, through the capillaries in the vaporization plate, and into the vaporization chamber flowing outwardly and downwardly along the top surfaces of the plate for vaporization of the liquid contaminants. The reconditioned oil flows out the oil outlet while the vaporized liquid contaminants flow from the device through the vent.

Dependent claims

An oil reconditioning device for removing solid and liquid contaminants from lubricating oil comprising:

a housing having an inlet at a lower end;
an oil filter chamber in the lower portion of said housing;
a filter in said filter chamber for removing said contaminants from said oil;
a preheating chamber in said housing above said filter chamber;
a hollow convex frustoconical vaporization plate comprising a plurality of concentric tiers within said housing on said filter above said filter chamber, the uppermost tier of said vaporization plate being provided with a plurality of circumferentially spaced capillaries for flow of oil and contaminants through said plate;
the bottom face of said vaporization plate defining the roof of a frustoconical preheating chamber between said filter and said vaporization plate for initially heating oil and liquid contaminants to vaporize the more volatile of said contaminants;
the top face of said vaporization plate defining the floor of a vaporization chamber within said housing;
