Abstract

The present invention relates to an automobile engine oil filter using a five twill and, more particularly, to an automobile engine oil filter using a five-twill metal mesh which is capable of increasing a passing flow rate to correspond to an oil pressure. The present invention weaves a filtering mesh of an engine oil filter as a five-twill metal mesh to form a rectangular-shaped net opening with dimensions of 25㎛ to 70㎛ in width and length. As such, in a normal pressure state, when even any one dimension of width and length dimensions exceeds a target dimension, the present invention, regardless of the shape, performs filtering by means of a rectangular-shaped net opening with dimensions of 25㎛ to 70㎛ in width and length and supplies lubricating oils, thereby preventing the inner wall of an engine from being damaged, and when the engine oil pressure rapidly increases due to high-speed driving, the intersection gap between a perpendicular line and a horizontal line of a ridge part is widened so that the net opening is substantially enlarged, thereby promoting the circulation of engine oil and maintaining a lubrication function and a cooling function for each element of the engine. Therefore, the present invention has useful effects of improving performance of an engine and lengthening the lifetime of the engine.

Description

Automotive engine oil filter using 5 twill weave

The present invention relates to a vehicle engine oil filter using a five twill weave, and more particularly to a vehicle engine oil filter using a five twill weave metal mesh to increase the flow rate corresponding to the oil pressure.

As is well known, a typical vehicle engine oil filter is provided with a filter element inside thereof to filter and supply circulating lubricating oil to prevent damage to the engine inner wall due to foreign matter.

The vehicle engine oil filter using the filter paper may damage the element made of the filter paper as the pressure increases when the vehicle is traveling at high speed, thereby deforming the folded portion in the accordion shape, and when the filter paper partially ruptures due to excessive pressure, In addition, there is a problem such as causing a shortening of the life of the engine, as well as a vehicle engine oil filter using such filter paper is a problem that has become a factor of environmental deterioration because it is impossible to recycle after normal use.

In order to solve this problem, in the past, the engine oil filter of the vehicle was used as a filter material by weaving a mesh made of metal yarn instead of a paper material, and a typical example thereof was Korea Utility Model Registration No. 20-196661 (designated name: lubricant filter; Citation invention '.

Looking at the structure of the cited invention as shown in Figure 1, it is installed and has a cap housing 110 having a capstiffener 111 formed in the inlet 114 and outlet 115, and built in the cap housing 110 A filter installed to filter the lubricant flowing into the inlet 114 and discharge the lubricant to the outlet 115, and installed between the cap stiffener 111 and the element so that the lubricant does not flow back into the inlet 114. In the lubricant filter including a valve 140, the spring 130 is installed in the cap housing so that the element is in close contact with the cap stiffener 111,

The element 120 is installed between the upper and

lower caps

121 and 122 made of metal and the upper cap 121 and the lower cap 122, and the thick lines 123a and the metal which are interweave with each other. It is characterized in that it comprises a filter net 123 made of a thin line 123b, as shown in Figure 2 the thick line 123a of the filter net is 0.2mm ~ 0.4mm, the thin line 123b Lubricating oil filters have been disclosed to be 0.1 mm to 0.3 mm.

In addition, the present invention is the inner cap 125a formed in the element inner direction on the lower cap 122, the valve plate 125b installed in the center of the lower cap 122, the inner cap 125a and the valve plate ( It further comprises a safety valve 125 composed of a safety valve spring (125c) installed between the (125c).

According to this cited invention, as shown in FIG. 2, the filter net 123 made of metal yarn for filtration of lubricating oil is a flat weave, and an enlarged picture of the structure of the flat weave is shown in FIG.

As can be seen, plain dutch weave is a clan of plain weaves with a thick diameter of vertical lines, a diameter of thin horizontal lines, enlarges vertical meshes, and horizontal meshes in close contact. Weaving allows liquids or gases to pass through at intervals between the longitudinal and horizontal intersections.

Accordingly, the mesh of the flat weave becomes narrower as the distance between the vertical line and the horizontal line becomes farther away from the vertical line, as shown in the enlarged portion B of FIG. 4, so that the shape of the mesh is formed into a triangle.

Therefore, in order to make the mesh of the filter network by the flat weave mesh to be suitable for engine oil filtration, the diameter of the circle as shown by the dotted circular line of FIG. The length is more than two times, and thus, if the thickness is thin, there is a problem that the filtration function is lost by being able to pass up to the foreign matter much longer than 140㎛ length.

That is, if the diameter of the circular dotted line portion shown in Fig. 4 is 20 μm, if the thickness is thin, foreign matter having a length of 40 μm can pass, and if the diameter of the circular dotted line portion is 70 μm, the thickness is thin and long. There is a problem that the foreign matter having a length of more than 150㎛ can also pass through the loss of the filtration function.

In addition, a pressure of about 3.5 kg / cm 2 is normally applied to the engine oil filter, but during the high-speed rotation of the engine, it is required to increase the flow rate while the pressure increases significantly. Since the diameter of the wire is large and the horizontal lines are arranged at narrow intervals, the increase in flow rate is not sufficient. Therefore, the valve plate 125b is pushed by the hydraulic pressure of the safety valve 125 which is increased so that the lubricant flows directly into the element 120. By doing so, it is possible to be discharged without the filtration process to correspond to the increase in the flow rate, thereby exposing the problem of losing the filtration function and satisfying only the flow rate.

An object of the present invention is to fabricate a filter net woven by metal yarn of the engine oil filter in order to solve this problem, the horizontal and vertical of the mesh by the vertical and horizontal lines of the filter net in a square to accommodate the diameter of 25㎛ to 70㎛ By keeping it close, it prevents foreign substances from passing over the specified size, and a large increase in pressure during high-speed rotation of the engine allows a large amount of engine oil to pass through the gap between the horizontal and vertical lines, thereby providing sufficient flow rate. In order to provide a vehicle engine oil filter using a five-twill metal mesh that can be made.

In order to achieve the above object, the present invention provides a vehicle engine oil using a five-twill weave metal mesh fabricated by weaving to form a square-shaped net having a width and a length of 25 to 70 μm. Suggest a filter.

In this way, the present invention is filtered under any pressure, regardless of the form of any one of the horizontal and vertical specifications by the square net of the horizontal, vertical 25㎛ to 70㎛ in the normal pressure state regardless of the form By supplying lubricating oil, it prevents damage to the engine inner wall, and when the engine oil pressure increases due to high speed driving, the gap between the vertical line and the horizontal line of the ridge increases, resulting in a substantial expansion of the manhole. By promoting circulation, the lubrication and cooling functions for each element of the engine can be maintained, improving the performance and extending the life of the engine.

With reference to the accompanying drawings, the present invention will be described in detail with reference to the embodiments of the present invention to be easily carried out by those skilled in the art as follows.

The engine oil filter for a vehicle using the five-twill metal mesh 301 to which the present invention is applied, as shown in FIG. 5, includes a capstiffener 200 having an inlet 201 and an outlet 202, and the capstiffener 200. ) Check valve 203 to prevent backflow, a metal mesh 301 woven by vertical lines 308 and a horizontal line 307 to filter engine oil, and upper and lower metal meshes 301 Filtration means 300 consisting of an upper cap 302 and a lower cap 303 having a through hole 304 fixed to the upper and lower portions of the valve plate 403 are installed below the filtering means 300. A bypass valve 400 having an inner spring 401 and an outer spring 402 installed therein, and a housing 500 for accommodating the cap spring 200, the filtering means 300, and the bypass valve 400. In the vehicle engine oil filter, such a configuration will be known.

As shown in FIG. 7, which is a partially enlarged view of FIGS. 6 and 6, the metal mesh 301 of the filtering means 300 of the vehicle engine oil filter has four horizontal lines 307 crossing four vertical lines 308. After the jump, the transverse ridge 305 is formed by crossing the vertical line 308, and the vertical 308 also crosses the horizontal line 307 after four crossings of the horizontal line 307. The mesh formed by the lateral line 307 and the vertical line 308 is made into a quadrangular shape by the weaving with the five-twill metal mesh 301 constituting the square) and the size of the mesh is 25 μm in the horizontal (a) and the vertical (b), respectively. The diameter of the horizontal line 307 and the vertical line 308 is made into the range of 100 micrometers-200 micrometers.

The engine oil filter for a vehicle according to the present invention is woven in five twills, and is woven by vertically intersecting a horizontal line 307 and a vertical line 308 of the same diameter, as shown in FIG. The mesh also has a horizontal shape (a) and a vertical shape (b) of substantially the same size rectangular shape.

Therefore, the present invention is that the mesh is the most preferred size range (a) and length (b) is in the range of 25㎛ to 70㎛ so that any foreign matter of 25㎛ to 70㎛ or more on any one side of the metal mesh 301 ), The circulation is blocked, so that the engine inner wall or the piston circumferential surface is prevented from being damaged by foreign matters, thereby protecting the engine.

In addition, in the present invention, the thickness is sufficient in a normal pressure state of about 3.5 kg / cm 2, and as shown in FIG. 9, the solid lateral ridges 305 and the longitudinal ridges 306 are vertical lines 308, respectively. By setting the intersection of the lateral line 307 and the set net size is to be able to perform the filtration function.

In addition, when the engine oil pressure suddenly increases during the high speed rotation of the engine, as shown in Fig. 10, the lateral ridge 305 and the longitudinal ridge 306 are formed between the vertical line 308 and the horizontal line 307, respectively. As the gap between the gap and the gap is widened, the net is substantially enlarged.

Accordingly, when the engine oil pressure increases rapidly, the mesh is enlarged to decrease the fluid resistance, thereby promoting the circulation of the engine oil to promote the lubrication and cooling functions for each element of the engine, thereby improving performance and prolonging the engine life. You will be able to.

In this way, when the engine oil filter is replaced for a long period of time, the foreign matters falling from each element inside the engine flow into the inlet 201 of the filter and cannot be passed through the metal mesh 301, and is pure engine oil. Only the bar passes through the metal mesh 301 and is discharged to the outlet, and when foreign matters that do not pass through the metal mesh 301 accumulate, the mesh hole of the metal mesh 301 loses its function and the flow rate decreases. When the engine rotates at a high speed, a high pressure engine oil that does not pass through the metal mesh 301 overcomes the elasticity of the inner and

outer springs

401 and 402 of the bypass valve 400 and pushes the valve plate 403 to inlet ( After entering the housing 500 in 201, there is a possibility of being discharged to the outlet 202 through the through hole 304 without being filtered. Therefore, it is a matter of course to replace the engine oil filter periodically before this situation occurs.

In addition, the present invention discloses a vehicle engine oil filter using a five-twill weave metal mesh 301, and the reason for the present invention is limited to the five-twill weave metal mesh 301 as described above. 301 is used as a vehicle engine oil filter, the transverse ridge 305 and the longitudinal ridge 306 are not sufficiently separated from the vertical line 308 and the horizontal line 307 when the engine oil pressure rises. There is a problem that does not correspond to the increase in the flow rate during high-speed rotation, and as a result of using as the engine oil filter for a vehicle using a metal mesh 301 or more twill weave lateral ridge 305 and longitudinal ridge when the engine oil pressure rises The 306 is excessively spaced apart from the vertical line 308 and the horizontal line 307, and the restoration to the exact original position may occur. Ridges 306 When the engine oil is in the normal pressure range while the engine oil is in the normal pressure range while being spaced at an optimum distance from the line 308 and the horizontal line 307, the lateral ridge 305 and the longitudinal ridge 306 are correctly returned to their original positions. The size of the mesh is returned to its original state by returning, and thus it is possible to perform a repeating faithful filtration function.

In addition, in the present invention, the five-twill metal mesh 301 may use a stainless steel wire having corrosion resistance and various materials having elasticity and corrosion resistance. In addition, in the present invention, the wire diameter of the horizontal line 307 and the vertical line 308 constituting the transverse ridge line 305 and the longitudinal ridge line 306 while maintaining the size of the mesh in the range of 25 μm to 70 μm When the diameter is less than this range, it is highly likely to be deformed or damaged by the engine oil pressure, and when the diameter exceeds this range, the lateral ridge 305 and the longitudinal ridge are Despite the increase in the engine oil pressure, the 306 maintains its position due to the rigidity so that the size of the mesh is not expanded so that the flow rate can be increased when the engine oil pressure is increased while maintaining the rigidity of the metal mesh 301. In order to make it possible, the wire diameters constituting the lateral ridge 305 and the longitudinal ridge 306 are limited to 100 µm to 200 µm.

In addition, the present invention shows an example in which the lateral ridges 305 and the longitudinal ridges 306 are formed in the horizontal direction and the vertical direction, but as shown in FIG. 10, the five lateral ridges in the lateral direction only. A portion 305 is formed so that the vertical weave portion 305 is perpendicular to both sides of the vertical line 308 and the horizontal line 307 intersecting the vertical line 308 and the horizontal line 307 is provided with a solid weave of the plain weave 310 portion By doing so, the flat weave mixed five-twill metal mesh can be secured in the longitudinal direction and secured in the longitudinal direction, and a modified embodiment capable of securing the flow rate corresponding to the increase in the pressure of the engine oil can be implemented. The form may be more suited to high speed engines where very high engine oil pressure rises occur.

In the present invention, the transverse ridge 305 or the longitudinal ridge 306 may be mixed with various weaving forms to be modified in various forms suitable for passenger cars, vans, vans and other special vehicles.

As mentioned above, this invention is not limited to the above-mentioned embodiment, It is possible to vary and implement within the summary and concept which this invention intends.
