[Detailed description of the invention] Separable evaporation and filtration elements Oil purification equipment with Background of the invention This application is a continuation in part of U.S. Patent Application No. 281,338, filed July 8, 1981. This is an application.

field of invention The present invention relates to a bypass oil purification device for an internal combustion engine. pie/? oil refining The device provides alternative flow of lubricating oil in automobiles and other machines using internal combustion engines. It is connected to the crankcase of the internal combustion engine through a channel.

Oil purification equipment penetrates the oil through a porous filter material and heats the oil. to evaporate and remove volatile contaminants such as water and fuel.

Description of prior art Contaminated lubricating oil used in internal combustion engines can be used in engine parts and related equipment. Excessive force is the main cause of wear and deterioration. Currently, in most internal combustion engines, Remove materials such as dust, carbon, soot, metal particles and other similar foreign objects from lubricating oil. Only one conventional mechanical filter is used to remove the particles. condensate, Liquid contaminants such as water and fuel are often emulsified in lubricating oils and are cannot be separated by a filter. Therefore, such conventional mechanical filters The lubricating oil used in the internal combustion engine does not cause damage to the engine due to contaminants entrained in it. It is necessary to alternate at uniform intervals to minimize damage.

In recent years, the global price of petroleum products has increased, and the use of lubricating oil has become limitless. There is a pressing need to develop purification systems that can be reconditioned and reused. It has become. In this way, a small amount of additional lubricating oil is added to the engine. required depending on the method.

The problem of liquid contaminants arises and heat is used as a mechanism to separate oil and contaminants. Considerable efforts are being made to develop devices. This type of equipment is Patent No. 2.635.759 and No. 2.839.196, Seewalji (Sc Barro: U.S. Patent No. 3,550.781, Barro w): U.S. Patent Nos. 3,616,885 and 4.006,084, Pr1est: U.S. Patent No. 4,146,475, Forcera Forsland: and Applicant's U.S. Patent Application No. 281,33 No. 8 (published on July 8, 1981 @).

Several problems have prevented the widespread use of oil refining equipment in automobiles. was there. One problem unique to conventional oil refinery equipment is that such units It is fleeting and expensive. Removal of both solid and liquid entrained contaminants To achieve this, it was necessary to create an elaborate evaporation chamber. conventional evaporation chamber are formed from intricately cast and machined steel or iron parts. like this These complex structures are expensive to manufacture and are also very heavy. However, flows into the oil refiner and forms a pattern to release volatile contaminants from the oil. Until now, it was thought that it was necessary to use the above structure to do this.

Another problem that has existed with conventional oil refinery equipment is the lack of adequate oil handling capacity. Provide adequate space under the vehicle hood in the engine compartment to accommodate the oil purification system. It is something that cannot be used. Traditional oil refinery equipment is a single structure It uses an evaporation section and a filtration section housed within or connected to each other. big en Vehicles with engines have to handle more oil than smaller engines. Therefore, an oil purification device with a correspondingly large capacity is required. but However, larger engines are bulkier and require less space near the engine. The space under the vehicle hood is always at a premium. Lubrication contained within the engine The larger conventional oil purification equipment required to properly purify the oil Always too large to fit within the available space under the vehicle hood was often the case.

Yet another problem with conventional oil refining equipment is that it Requiring a large number of different types of oil purification equipment of different sizes to be adaptable It is. Automotive oil refining equipment dealer provides oil refining for numerous vehicles. We stock many different types of oil purification equipment so that we can provide equipment It was necessary to keep it. Each vehicle has lubricating oil used in its engine. Must have oil purification equipment with a filtration section of sufficient volume to filter be. However, the volume of oil purification equipment is available within the vehicle's engine compartment. It cannot be made so large that it exceeds the available space. As a result, certain vehicle oil purification equipment It was necessary to design many orders. Any specific type of oil purification equipment Due to the limited market for The need for large inventories of different types of oil refining equipment reduces Selling costs increase.

Summary of the invention The present invention provides an improved oil purification device formed with separable evaporation elements and filter elements. It is. The evaporative element is attached to the vehicle's engine compartment inside the vehicle's engine compartment by means of a bracket. attached to the di structure. Evaporative elements are reusable components of oil purification equipment. Reeds, replaced, ie not replaced. Filter element can be removed from evaporation element It is a removable disposable cartridge that is connected to the device. filter cartridge The captured solid contaminants are transferred to the porous filter media located within this cartridge. Once deposited underneath, it is replaced periodically.

In operation of the bypass oil purifier 1o, the heated contaminated oil is passed through the inlet pipe 149. The contaminated oil inlet fitting of the filter cartridge 48 rises from the body through the fitting. It's in the 20s. The oil permeates through the cotton filter 54 and rises to this filter. The largest solid contaminants are removed and captured. The oil then flows upwards. , the flow passes through one layer of micropaper and a felt filter 80 between these layers. , where fine solid contaminants are removed from the flowing oil. Next, Oi The filter cartridge 48's filtered oil outlet fitting passes through the body 95 under pressure. and directly as in the embodiment of FIG. 3 or directly as in the embodiment of FIG. The filtered oil inlet of the evaporative element 12 is fitted through the hose 47 as in into the body 28.

The oil enters the pressure chamber 38 of the body 28 when the filtered oil inlet of the canister 14 is installed. When you are under pressure.

Restriction orifice 140 restricts the flow of oil through pressure chamber 38 and reduces the pressure therein. Increase power. The hot, partially contaminated oil in the pressure chamber 38 causes the evaporative bulkhead 34 to It acts to assist in heating from below. Oil is squeezed through orifice 140 When the debris comes out, it is ejected upward as a jet and collides with the convex protrusion 66. The protrusions disperse the oil radially outwardly through the atomizing screen 124. Turn the oil into droplets.

Once the oil leaves the restriction orifice 140, the oil no longer flows through the restriction. Since there is no one there, the pressure suddenly drops. Therefore, the pressure inside the evaporation chamber 16 is equal to the pressure inside the pressure chamber 38. much lower than the pressure of In addition, the electrical resistance heating element 26 and the parts may not be publicly contaminated. The heat given to the body 28 by the evaporator nozzle installation is lowered by the oil and the pressure is lowered by the oil. It acts to evaporate any liquid contaminants left in the oil. These evaporated pollutants It is discharged through vent 18.

As long as the pressure inside the evaporation chamber 16 remains above the normal flame pressure, the released steam will flow through the vent. from the vent inlet opening 138 through the vent passageway 136 to the vent outlet opening 144. flows to However, if the pressure in the evaporation chamber 16 drops to atmospheric pressure, the nylon Ball 142 falls and blocks vent opening 138 and allows ambient air to enter evaporation chamber 16. Avoid being sucked. When the evaporation chamber 16 is full of oil, the nylon bulb 142 floats up and blocks the drain opening 144 to prevent oil loss through the vent 18. Stop.

The atomized oil droplets collect on the floor 5θ of the evaporation chamber and reform as a liquid. When the liquid level rises, The oil flows from the evaporation element 12 through the lateral outlet mounting formed in the canister wall. It passes through and is discharged.
