Description

Drain device of remaining oil in oil filter for automobile}

The present invention relates to an apparatus for discharging residual oil of an automotive oil filter, and more particularly, by directly forming a drain passage for discharging the residual oil of an oil filter to an oil pan through a housing, so that the drain passage separately installed can be deleted. The workability is improved because there is no need to secure a space for installing the drain passage in the narrow housing. In addition, since the drain passage is not manufactured separately, the work cost for installing the drain passage is saved as well as the parts cost. It relates to a residual oil discharge device of the automotive oil filter that the productivity is improved by that.

In general, the engine of an automobile has a combustion gas temperature of more than 2000 ° C when fuel is burned in a cylinder, but a considerable amount of heat is absorbed by a cylinder, a cylinder head, a piston, and the like. Oil is injected and used for this purpose.

These oils prevent friction because the friction part such as the sliding part between the cylinder and the piston, the crank shaft and the cam shaft, etc. are in direct contact with the metals, and the frictional heat is generated, which eventually causes the contact surface to be worn or pressed. Oil is supplied / circulated to each friction part or sliding part of the engine.

At this time, the oil pumped from the oil pump passes through the oil filter to remove foreign substances, and then is supplied to each lubrication part of the engine. In this process, the oil filter removes dust generated from each sliding part of the engine or carbon generated from the combustion process. It will be filtered.

Therefore, the oil must be supplied with clean oil without impurities, so the oil filter is installed to remove foreign substances so that only pure oil is supplied. The oil filter is a full flow type, bypass type flow type, or combination according to the filtration method of the lubricating oil. It is roughly divided by the formula.

The full follower type is a method of filtration of all the oil discharged from the oil pump, which is commonly used in automobile engines.

The bypass flow type filters the part of oil discharged from the oil pump and returns it to the oil pan, and supplies the remaining oil to each part of the engine. The combination type combines the two types of flow type and bypass flow type described above. Most of the oil is filtered in a full-flow filter and fed to each part of the engine.

The oil filter is largely divided into a housing and a filtering element. That is, a filtering element for filtering foreign substances contained in oil is installed inside the metal can-shaped housing, and a cap for removing and mounting the filtering element is formed on the upper portion of the housing. In the lower part of the cap, a core fitted with an upper end of the filtration element is installed to move the cap and the filtration element together. When the cap is separated from the housing, the filtration element is also separated from the housing.

 And the lower part of the housing is formed with a main gallery connecting passage for guiding the oil filtered in the filter element to the main gallery of the engine, a drain passage for installing the oil to the oil pan during maintenance of the oil filter is installed.

In the middle of the oil pan connecting passage, a drain valve is installed to open the oil pan connecting passage so that the residual oil contained in the housing can be led to the oil pan when the filter element is removed. It is introduced into the oil pan through.

When the oil filter is in a normal state, the drain valve is pressed down at the bottom of the filtration element so that the oil purified from the filtration element is formed to be guided only to the main gallery connecting passage.

However, there are many problems with the drain passage for discharging the residual oil into the oil pan as follows.

In recent years, as the material of the filter element embedded in the oil filter is improved, the function of filtering the oil is excellent even if the size is small, so that the filter element can be made small accordingly, so that the housing in which the filter element is installed can be made as small as that.

As the housing becomes smaller in this way, when the oil filter is separated from the housing, it is difficult to secure a space for installing a separate drain passage for discharging the oil remaining in the housing to the oil pan. As well as the additional cost for the work is required to install the drain passage, so there was a problem that the productivity is reduced.

Accordingly, the present invention is to solve such a conventional problem, an object of the present invention is to install the drain passage in the housing according to the remaining oil can be discharged to the oil pan without separately installing the drain passage in the housing The workability is improved because there is no need to secure space, and the cost of parts for manufacturing drain passages can be reduced, and the working time for installing drain passages can be saved. It is to provide a residual oil discharge device.

In order to achieve the object of the present invention, the present invention is an automotive oil in which a filtering element having a drain core at the center is mounted in the oil filter mounting portion of the housing by a cap, and residual oil at the bottom of the oil filter mounting portion is discharged through the drain passage. In constituting the residual oil discharge device of the filter, the first to fourth drain passages are formed to be directly connected to each other by drilling the inside of the body of the housing at different angles so as to lie under the oil filter mounting portion, the first drain passage It is connected to the drain inlet formed at the bottom of the oil filter mounting part, and the hole inlet formed when the fourth drain passage is processed becomes a drain outlet connected to the cylinder block, and the outer wall of the housing when the first to third drain passages are processed. The hole inlet formed in the seal is characterized in that it is sealed by the sealing means.

As such, the present invention eliminates the need to secure a space for installing the drain passage in a narrow housing, since the drain passage can be deleted by directly forming a drain passage in the housing itself, thereby improving workability. In addition, since the drain passage does not have to be manufactured, the cost of parts can be reduced and the cost can be achieved, as well as the time required for installing the drain passage, thereby saving productivity.

Hereinafter, with reference to the accompanying drawings, the technical configuration and operation effects as a preferred embodiment that can effectively achieve the features of the present invention will be described.

According to the present invention, the filter element 120 having the drain core 110 at the center thereof is mounted in the oil filter mounting portion 210 of the housing 200 by the cap 100, and the remaining portion of the bottom of the oil filter mounting portion 210 is provided. In constructing a residual oil discharge device of an automotive oil filter in which oil is discharged through a drain passage, the inside of the body of the housing 200 is directly drilled at different angles at different angles so as to lie under the oil filter mounting portion 210. First to fourth drain passages 220, 230, 240, and 250 are formed to be connected, but the first drain passage 220 is connected to the drain inlet 211 formed at the bottom of the oil filter mounting portion 210. .

When the fourth drain passage 250 processes the hole inlet, the drain outlet 251 is connected to the cylinder block, and the first to third drain passages 220, 230, and 240 are processed. The hole inlets 221, 231, 241 formed on the outer wall of the housing 200 are sealed by a sealing means.

The present invention as described above when the cap 100 is installed in the housing 200, the drain core 110 and the filter element 120 is installed in order to replace the oil filter on the bottom of the oil filter mounting portion 210 of the housing 200 It is a general technical configuration to allow the remaining residual oil to be discharged to the oil pan (not shown) through the drain passage through the cylinder block (not shown).

However, in the present invention, a narrow housing 200 is formed by drilling a hole directly in the housing 200 without installing a drain passage for discharging the residual oil remaining in the housing 200 to the oil pan as a separate component. It is not necessary to secure a space for installing the drain passage separately in the inside, so that the workability is improved. In addition, since the drain passage does not have to be manufactured, the cost can be reduced and the cost can be saved. Work time is also saved by the productivity can be improved.

That is, the present invention forms the first, second, third, fourth drain passages 220, 230, 240, 250 by directly drilling holes in the drain passages as shown in FIGS. 1 to 2. However, the first drain passage 220 is connected to the drain inlet 211 formed at the bottom of the oil filter mounting portion 210, and the hole inlet formed when the fourth drain passage 250 is processed is a drain outlet connected to the cylinder block ( 251) was formed.

Therefore, when the cap 100 is removed from the housing 200 to replace the oil filter, the drain core 110 and the filtering element 120 are lifted together with the cap 100, and the oil filter mounting portion 210 of the housing 200 is removed. The remaining oil remaining on the bottom flows into the first drain passage 220 through the drain inlet 211, and then continues through the second drain passage 230 and the third drain passage 240 in order to discharge the fourth drain. After entering the passage 250, it flows into the oil pan through the cylinder block through the drain outlet 251.

The first drain passage 220, the second drain passage 230, the third drain passage 240, and the fourth drain passage 250 may be formed at different angles from each other in the housing 200. This is to form a drain passage without interference.

In addition, in the present invention, when the first drain passage 220, the second drain passage 230, and the third drain passage 240 are processed, hole inlets 221, 231, and 241 naturally occurring on the outer wall of the housing 200. ) Should be blocked by a sealing means when the residual oil moves along the first drain passage 220, the second drain passage 230, and the third drain passage 240 to enter the oil pan. It does not leak out of the housing 200 through the 231 and 241.

Here, as the sealing means for blocking the hole inlets 221, 231, 241 of the first drain passage 220, the second drain passage 230, and the third drain passage 240, a hole may be used. It is preferable to install the steel ball 300 by forcibly pressing the inlets 221, 231, and 241.
