Description

[0001] The present invention relates to an oil filter and an oil filter including the oil filter,

The present invention relates to an oil filter and an oil filtering apparatus including the oil filter.

Generally, an oil filtration apparatus filters out impurities such as sludge, carbon, dust, and metal powder contained in oil, thereby maintaining the oiliness of a high-purity oil. In addition, moisture contained in the oil is removed to ensure the stability of the device. Currently, various filtration devices for filtering impurities in oil have been developed.

As is known, the oil filter element used in automobiles filters dust, carbon, metal powders, oxidation products, etc. mixed with oil, and usually has to be changed every 5,000 to 10,000 kilometers when traveling at a relatively short distance.

This is because, when the oil filter element is filtered while impregnating the oil with the impurities, the impurities are present in the element while the vehicle travels at the above travel distance, resulting in an increase in the pressure with the oil.

Therefore, when the oil pressure is increased, the oil pressure is excessively caught in the lubrication circuit, and in a severe case, the oil filter may be ruptured.

An object of the present invention is to provide a highly reliable oil filter and oil filtration device for filtering contaminated oil.

Another object of the present invention is to provide an oil filter and an oil filtration device capable of reducing the number of filter replacement times and reducing the maintenance cost of the device.

According to an aspect of the present invention, there is provided an oil filter having an internal cavity and an inlet, which is a passage through which oil flows, and an outlet through which the filtered oil flows, A first filter for filtering the metal material contained in the oil introduced into the oil inlet through the inlet; A second filter disposed on the first filter for filtering fine impurities contained in oil that has passed through the first filter; A housing for inserting the first filter and the second filter therein, and a cover coupled to one side of the housing to seal the housing.

In particular, the present invention is characterized in that a branch pipe is formed at the center of the first filter and the second filter so as to allow the oil filtered through the first filter and the second filter to flow therethrough.

In particular, the first filter comprises a first filter body for filtering contaminants of contaminated oil;

A first upper fixing member formed to be fixed to the second filter on the first filter body; And a first lower fixing member fixed to the cover under the first filter body.

Particularly, at one side of the first lower fixing member, an inlet for introducing contaminated oil from the outside and an outlet for discharging the oil filtered out from the first filter and the second filter are formed .

In particular, the first filter body is characterized in that the circumference is formed in a zigzag, corrugated hollow cylindrical shape.

In particular, the second filter comprises a second filter body for filtering contaminants of contaminated oil;

A second upper fixing member formed on the second filter body to be fixed to the inner surface of the housing; And a second lower fixing member formed to be fixed to the upper portion of the first filter below the second filter body.

In particular, the second filter member is characterized in that the filter member is formed in the form of a roll tissue around the cylinder.

In particular, the cover and the inner surface of the housing are formed with projections in the form of a screw and are fastened to each other.

According to another aspect of the present invention, there is provided an oil filter for a vehicle, comprising: the oil filter according to any one of claims 1 to 8 and connected to the oil filter to operate a pressure pump in the vehicle, And the refined oil flows out to the oil reservoir.

In particular, the oil filter includes a first filter and a second filter.

The effects of the present invention are as follows.

First, the filtration efficiency of the impurity-added oil can be increased.

Second, it is possible to reduce the cost by replacing the filter by extending the filter replacement cycle.

Third, metal materials and fine impurities can be double filtered to maintain the purity of the filtered oil.

In particular, the nonwoven fabric may be composed of a nonwoven fabric, and the nonwoven fabric may be laminated and wound and formed into a cylindrical shape. Nonwoven fabric type filter bodies are mainly suitable for filtering impurity particles of a specific size or larger. Further, the second filter body 122 may be formed of a thread. An actual type of filter body is suitable when the impurity particles have a wide size distribution. The second filter body 122 may be a composite type filter body of a yarn type and a nonwoven fabric type, and the adsorbent may be inserted between the yarn and the nonwoven fabric when wound in a cylindrical shape.

The second upper fixing member 125 and the second lower fixing member 121 serve to fix the second filtering member 122 so as not to be loosened and the oil filtered by the first filter 110, So as to flow along the branch tube formed at the center of the filter body. A branch pipe is formed in the center of the first filter 110 and the second filter 120 so that the oil filtered through the first filter 110 and the second filter 120 flows . That is, the branch tubes 170a and 170b are cylindrical tubes passing through the center of the filter body, and the purified oil passing through the filter body is collected. In addition, a sealing portion 171 may be provided at a lower portion of the branch pipe of the first filter to seal the gap between the branch pipe and the passage at the center portion.

7 is a view schematically showing the structure of the cover of the present invention. 7, protrusions are formed in the inner surface of the cover 140 and the lower end 131 of the housing 130 and are fastened to each other.

The housing 130 has durability to withstand the hydraulic pressure, and the inside of the body into which the oil flows is formed into a hollow cylindrical shape. Also, the housing 130 may be made of a plastic material or a metal material that is not easily corroded by moisture or the like. The inside of the housing 130 is a portion into which the oil filter is inserted, and is a space where actual filtration of oil proceeds. In general, the interior of the housing 130 is sealed by the assembly with the cover 140, and the inlet 151 and the outlet 161 formed in the first lower fixing member 111 of the first filter 110, There is only a hole in the position, and there is only the inflow and outflow of oil.

The cover 140 is formed with a resilient member 145 at its center so that the first and second filters 110 and 120 are fixed within the housing 130. At this time, the elastic member 145 may be formed in a spring shape of a metal material, but is not limited thereto.

An oil pump 200 as an in-vehicle pressure pump is connected to the oil filter 100 to introduce unrefined oil in the oil reservoir 300 into the oil filter 100, And flows out to the oil reservoir 300.

At this time, the oil filter 100 includes a first filter 110 and a second filter 120, and at least one of them may be a roll-tissue filter.

First, the oil introduced into the inlet of the oil filter 100 through the oil hose 400 filters the metal impurities contained in the oil through the first filter 110, (120) to filter out fine impurities. The oil that has passed through the second filter 120 moves to the oil reservoir 300 through the oil hose 500 connected to the outlet 161.

Therefore, the oil filtration apparatus of the present invention is characterized in that the oil filter 100 according to the first embodiment of the present invention, which functions as a full-flow filter, contains impurities or metal impurities having relatively large particles contained in the inflowed crude oil It is possible to perform filtration with a higher purity oil and to minimize clogging and damage of the oil filter 100, thereby prolonging the life of the filter.
