Abstract
A lubrication oil filter device has an attached electromagnet or permanent magnet (20) wound around the housing (10) which encloses a filter of rolled paper (30) between the inlets (13) and outlet (11). When the oil with fine iron particles from the cylinder flows through the device, the fine iron particles will not penetrate the rolled paper (30) but will be attracted by the magnetic force onto the inner wall of the housing so as to lengthen the life of the filter paper (30). <IMAGE>
Description
SPECIFICATION
A Lubricating Oil Filter Device
This invention relates to a lubricating oil filter device. As far as the lubricating system of an automobile is concerned, the general knowledge is that the friction in the cylinder would bring about the penetration of the fine iron particles into the lubricating oil. The failure to defecate the unexpected fine iron particles would be followed by the incomplete combustion of the fuel in the cylinder and further the leakage of combustioned air. A conventional method to solve this problem is to provide an oil filter device for the purpose of filtering the circulated lubricating oil in the lubricating system. However, the conventional lubricating oil filter device only teaches the application of a rolled paper filter coaxial in relation to the main body of the lubricating oil filter device.The rolled paper filter is provided between the main body thereof and a magnet which is provided within the main body. When the filtering of lubricating oil is in progress, the lubricating oil flows into the oil passage provided between the rolled paper filter and the main body thereof. The lubricating oil then flows outside from the outlet of the oil filter device. Due to the fact that the lubricating oil passes at first through the rolled paper filter during filtering, the fine iron particles would have an adverse effect on the paper filter. Further due to the fact that the magnet is attached on the inner wall of the paper filter and the passage for the lubricating oil to flow is not spacious, the more the fine iron particles are attracted on to the magnet, the less would be the capacity of the lubricating oil filter device.Besides, the accumulated fine iron particles would be peeled off in masses by the oil current and delivered to the engine. Hence, more damage may occur if this device has been in use for a long time. Therefore, the conventional lubricating oil filter device still has some defects and can be accordingly improved.
It is an object of this invention to improve the above defect, and to provide a lubricating oil filter for practical use.
According to the present invention there is provided a lubricating oil filter device comprising a metal cylinder which is pressed to form an open end which is covered by a plate with one hole in the center and a plurality of small holes around said center hole, said center hole being used as an oil outlet while the small holes are used for the oil inlet; a rolled filter paper for blocking most of the fine iron particles from the cylinder within the space between said cylinder and the outer surface of said filter paper which is coaxially provided within said cylinder, a set of electric windings secured on the outer surface of said cylinder, which when energized cause said metal cylinder to be magnetized and attract the fine iron particles in the lubricating oil into it, a hollowed metal column provided on the inner side wall of said rolled filter paper, said hollowed metal column being also magnetized during filtering so that some fine iron particles can be attracted thereupon.
The invention will now be described by way of example only with particular reference to the accompanying drawings wherein:
Figure 1 is a perspective view of this invention, partly broken away to better show the construction thereof;
Figure 2 is a fragmentary vertical sectional view illustrating the inner structure and outer attached windings or magnet of this invention and
Figure 3 is a fragmentary vertical sectional view of a conventional lubricating device.
Referring to Figure 1, this invention is provided with a cylindrical body 10 and one center outlet hole 1 1 with a female thread 12 for the oil pipe to screw thereupon. A set of rolled filter paper 30 is formed as a hollowed column and installed inside said body 10 to keep the fine iron particles from flowing therein. Said oil filter paper 30 made of the paper 31 of wrinkled type is also supported by a hollowed metal column 32 with many holes on its side wall, wherein one end of said hollowed metal column 32 is the outlet hole 11. Onto the outer side of said can body there is a set of windings or a hollowed permanent magnet 20.
Said set of windings 20 is usually made by winding on a circular frame and then put on to said can. When the wire is energized, said body 10 will be provided with magnetic force to attract the fine iron particles in the lubricating oil on to the inner wall of said body 10. Some fine iron particles will be attracted between the body 10 and the rolled paper filter 30. The hollowed metal 32 is also magnetized by the winding 20 so that it also can attract some fine particles. It is comparatively easy for the winding 20 to be examined and repaired. Since the winding 20 is wound onto the outer side of said body 10 and has no contact with the lubricating oil, the life of the filter device is therefore extended.
Usually, the engine and lubricating oil pump are stopped before the power supply is switched off. Therefore, the fine iron particles will not flow into the engine when the winding loses its energy.
When starting a car, the process is reversed so that there is also no problem in this respect.
Figure 2 shows a vertical sectional view of the invention illustrating the oil flow path when the lubricating oil is filtered. According to Figure 3, it can be seen that compared with the magnet of the oil filter device of the invention, the device of the prior art will easily be fully loaded and the rolled filter paper will be in a worn state very quickly.
In the present invention, the magnetic force is very strong and the area for the fine iron particles to be adhered upon is very large. Therefore, the lubricating oil can be kept from deteriorating so as to lengthen the life of the engine.
Since the lubricating oil filter device of this invention makes the smooth operation of the engine attainable, the fuel can be in complete combustion so that the combustioned air does not cause pollution. Especially, these characteristics can be easily seen by driving in a new car. It is obvious that this invention is really an improvement in the conventional lubricating oil filter device. The foregoing embodiment is described with particular reference to a car but the invention can be further used in a lathe, a machinery set the effect of which is the same as used in a car.
