Description

SUBSIDIARY DEVICE FOR OIL FILTER
Technical Field
The present invention relates to a subsidiary device for an oil filter, and more particularly to a subsidiary device for an oil filter which is capable of more effectively filtering foreign matters contained in engine-circulating oil, thereby maximizing the engine lubricating function of the oil while considerably extending the life of the oil filter.
Background Art
Fig. 1 is a sectional view illustrating an example of a conventional oil filter.
As shown in Fig. 1, the conventional oil filter, which is connected to the engine oil circulating system of a vehicle to filter foreign matters from engine oil, and denoted by the reference numeral 1, includes a housing 10 opened at a lower end thereof, a closing cover 20 fixed to the lower end of the housing 10 in accordance with a seaming process, and formed with a central hole 22 while being provided with a packing ring 21 mounted to the lower end of the closing cover 20 around the central hole 22, and a lower clamping member 30 coupled to an upper end of the closing cover 20 around the central hole 22, and centrally provided with a boss 31 having a vertical threaded outlet hole 33 while being provided at a lower end thereof with a flange 32 having a pluiality of inlet holes 34. The oil filter 1 also includes a diaphragm valve 40 arranged over the inlet holes 34 formed at the flange 32 of the lower clamping member 30, and a filter 50 including an upper plate 51, and a lower plate 52 coupled to an upper end of the boss 31 of the lower clamping member 30. The filter 50 also includes a filtering net 53, a filtering paper 54 and a porous plate 55, all of which are inteiposed between the upper and lower plates 51 and 52. The oil filter 1 further includes an overflow valve 60 centrally coupled to a lower surface of the upper plate 51 of the filter 50 such that it is downwardly directed, and adapted to control the discharge amount of oil, and a spring 70 elastically installed between the upper plate 51 of the filter 50 and the housing 10, and adapted to downwardly urge the filter 50 against the diaphragm valve 40.
When an engine, to which the above mentioned convention oil filter 1 is applied, operates, oil from an oil pan (not shown) is supplied into the oil filter 1 by an oil pump 2. The supplied oil passes through the inlet holes 34 under pressure while pushing the diaphragm valve 40 of the oil filter 1 in accordance with its pressure. As a result, the oil passes through the filtering net 53, filtering paper 54, and porous plate 55, in this order, so that foreign matters contained in the oil are completely filtered. Accordingly, only clean oil is supplied to each part of the engine, to be lubricated, through the central space of the filter 50, and the threaded outlet hole 33 at the lower end of the central space. The oil supplied to each engine part is then collected into the oil pan so that it is subsequently circulated.
When the oil introduced into the space around the oil filter 1 through the inlet holes 34 increases in pressure above a certain pressure as the amount of the introduced oil increases, it is downwardly discharged at the lower end of tlie central space of the filter 50 through an upper space defined above the filter 50, and the overflow valve 60.
However, the conventional oil filter 1 having the above mentioned configuration has a problem in that foreign matters having a relatively large grain size or metallic foreign matters contained in the oil supplied from the oil pump 2 are directly supplied to the filtering paper 54, so that the life of the filtering paper 54 is reduced, thereby causing the replacement interval of the oil filter 1 to be reduced.
Furthermore, the conventional oil filter 1 has a problem in that the supply of the oil to each part of the engine is delayed during an initial start-up operation of the engine, so that the engine suffers from an abrasion generated during the initial start-up operation.
In wintertime, the conventional oil filter 1 has a lengthened warm-up time because the oil exhibits an increased viscosity in a cooled state.

By these steps 165 and 166, the coupling of the oil discharging coupling bolt 160 can be accurately achieved.
Now, the operation of the subsidiaiy device according to the present invention will be described.
Contaminated oil emerging from the engine after circulating in the engine is fed from the oil pan under pressure to the space 114 defined by the cover 110, by a pumping operation of the oil pump. The oil is then supplied into the impeller hosing 120 via the oil passages 117. The contaminated oil transmits its pressure to the blades 151 of the impeller 150 while being supplied under pressure into the impeller housing 120, thereby causing the impeller 150 to rotate. In accordance with the rotation of the impeller 150, the rotating plate 153 is rotated. As a result, foreign matters contained the contaminated oil introduced into the oil passages 154 of the rotating plate 153 are cohered in accordance with friction generated between the mixer disc 140 and the rotating plate 153.
Here, those foreign matters may include stainless steel fragments generated at sliding parts of the engine, carbonic substances produced due to an incomplete combustion of the oil or fuel, oxide substances produced due to a degradation or aging of the oil, and dust introduced into the oil through the engine during an air sucking operation. These foreign matters are mixed and cohered in accordance with a pressure and friction generated by the rotating force of the rotating plate 153.
The contaminated oil with cohered foreign matters is upwardly moved via the oil passages 141 of the mixer disc 140, and then moved to the oil filter 1 via the oil passages 123 of the impeller housing 120. The foreign matters contained in the contaminated oil are collected on the upper plate 122 by the magnetic force of each permanent magnet 129 arranged between adjacent ones of the oil passages 123 of the impeller housing 120. The contaminated oil, from which a considerable amount of foreign matters have been removed, is then fed to the filter 50, so that it passes through the filtering net 53, filtering paper 54, and porous plate 55, in this order. As a result, the contaminant remaining in the oil is completely filtered. The resultant oil is then fed under pressure to tlie inner space of the filter 50. In particular, even non-metallic foreign matters are cohered as they are mixed with metallic foreign matters while passing through the impeller 150. Accordingly, most foreign matters are collected on the permanent magnets 146. Thus, it is possible to extend the life of the filter 50 to a maximum, and to supply again the oil in a contamήiant-free optimum state to the engine.
That is, the oil, which is clean in accordance with the filtering operation carried out during the feeding procedure thereof under pressure, is supplied to the engine via the oil-discharging coupling bolt 160. This operation will be described in more detail. As the engine operates, an oil sucking force is generated. In accordance with this oil sucking force along with the pressure of the oil fed under pressure, the actuating member 163 positioned within the oil-discharging coupling bolt 160 is downwardly urged against the spring 163 a, thereby opening the oil passage 165.
As a result, the filtered clean oil is supplied again to the engine via the main oil discharge hole 161.
Meanwhile, when the engine is stopped at a parked state of the vehicle, the oil sucking force of the engine and the pressure of the oil disappear, thereby causing the actuating member 163 to close the main oil discharge hole 161 by virtue of the resilience of the spring 163 a. At this time, a certain amount of filtered clean oil is left in the filter 50.
Accordingly, when the engine is started up again, the filtered clean oil can be immediately supplied to the engine, thereby preventing a reduction in lubricating effect occurring during the start-up operation. Thus, it is possible to prevent a reduction in the life of the engine while achieving an improvement in the power of the engine, and a reduction in waπn-up time.
When the internal temperature of the impeller housing 120 is sensed to be excessively low, that is, the oil exhibits an excessively low viscosity, the heating coil 130 is operated to rapidly heat the oil to a desired temperature. Thus, oil of an appropriate viscosity can always be supplied to the engine.
Thus, even when the engine is started up in a cooled state in wintertime, it is possible to reduce the warm-up time of the engine because the oil is supplied to the engine after being rapidly heated. It is also possible to avoid a reduction in the power of the engine and a reduction in the life of the engine caused by a cooled state of oil.
Meanwhile, the packing 116 mounted to the cover 110 is pressed between the cover 110 and the mounting section of the engine when the subsidiary device 100 is mounted to- the mounting section of the engine, thereby providing a reliable sealing effect.
When the filter 50 is contaminated beyond an allowable level, the oil filter 1 is separated from the subsidiary device 100 coupled to the mounting section of the engine to replace tlie contaminated filter.
The subsidiary device of the present invention can be mounted to any vehicles by appropriately varying the sizes of the oil-discharging coupling bolt 160 and clamping member 126. Thus, the subsidiary device of the present invention is usable for any vehicles.
Industrial Applicability
As apparent from the above description, the subsidiary device of an oil filter in accordance with the present invention includes: the cover 110 coupled to an oil pump; tlie impeller housing 120 coupled to the oil filter 1 while having a cylindrical structure opened at the lower end thereof, the impeller housing 120 being provided with the upper plate 122 having a plurality of oil passages 123; the heating coil 130 installed in the interior of the impeller housing 120, and adapted to heat oil introduced into the impeller housing 120; the mixer disc 140 arranged beneath the heating coil 130, and coupled to the heating coil 130; the impeller 150 rotatably mounted to the lower surface of the mixer disc 140 while being in close contact with that lower suiface; and the oil-discharging coupling bolt 160 adapted to couple the cover 110, heating coil 130, mixer disc 140, and impeller 150 to the impeller housing 120 while supplying filtered oil to the engine. In accordance with this configuration, it is possible to achieve an enhancement in the ability of the oil filter to collect foreign matters contained in oil during a lubricating operation of an engine, thereby achieving an efficient engine lubricating effect while achieving an enhancement in the power of the engine. The subsidiary device can rapidly supply oil to the engine parts, to be lubricated, simultaneously with a start-up operation of the engine, so that the engine is prevented from being abraded during its start-up operation due to a delayed oil supply, thereby lengtliening the life of the engine. It is also possible to prevent a warm-up time from being lengthened in wintertime due to an increase in the viscosity of the oil in a cooled state. The lift of the engine can also be lengthened. This reduces the expense taken for disposal of waste filters, thereby providing economic advantages. Since the amount of waste filters is reduced, a reduction in environmental contamination is achieved. It is also possible to rapidly supply oil simultaneously with an initial start-up operation of the engine.
