Description

Drain core combined oil filter for automobile

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil filter incorporating a drain core for an automobile, and more particularly, after inserting an element into an oil filter housing, a drain core having an oil ring coupled to the bottom of the element, in addition to the drain core for supporting the element, is integrated. When the element is inserted into the oil filter housing, the drain core of the element is formed to be precisely coupled to the coupling portion of the oil filter housing to increase the airtightness, thereby maintaining the airtightness under the element. Since it does not need to attach a separate fibrous material, such as to reduce the production cost of the product and relates to an automotive drain core integrated oil filter to simplify the production process.

In general, engine oil is contaminated by impurities such as metal wear particles, air dust, sand, carbon particles, and oxidation products of oil in proportion to the operating time during each friction, smooth lubrication and cooling of engine parts. Will be.

Continued operation of the engine in such a state causes wear and damage to each friction and rotating parts, and worsens damage to the crankshaft and the rotating parts.

The oil filter is an important part that keeps engine oil clean by filtering impurities that cause contamination and deterioration of the oil itself during engine operation.

In other words, the engine oil needs to be replaced after the car has traveled a certain distance. At this time, the oil contaminated by the oil discharge passage formed in the drain part of the oil filter housing to discharge residual oil in the oil filter housing to the oil pan. Will be discharged.

However, after the oil is exchanged, the bottom end of the drain core is provided with a sealing installation portion in which a plurality of O-ring grooves are formed so that the oil does not leak into the oil discharge passage of the drain portion until the next oil change. will be.

1 is a cross-sectional view showing an element and a drain core of a drain structure of a conventional automotive oil filter, and FIG. 2 is a cross-sectional view showing a drain structure of a conventional automotive oil filter.

After inserting the element 10 into the oil filter housing 80 as described above, the drain core 35 is inserted through the oil passage 15 formed in the element 10 to the oil filter housing 80. The element 10 is to be fixed.

At this time, in order to maintain the airtightness in the upper and lower parts of the element 10 is to be provided with a fiber material (70).

However, such a drain structure of the automotive oil filter has the following problems.

That is, since the element is inserted into the oil filter housing and the drain core, which is a separate part, is inserted through the oil passage of the element to fix the element, it is impossible to visually check whether the drain core is correctly fixed to the oil filter housing. When the core is inclined or eccentrically assembled, after the element and the drain core are coupled to the oil filter housing, oil leakage occurs.

In addition, even after the drain core is inserted into the oil passage of the element and combined with the oil filter housing, since the element and the drain core are separate parts, there is a play and oil is leaked. To separate the fiber material such as aramid to, but because the fiber material reinforcing the airtightness such as aramid was expensive, there was also a problem that the production cost of the product increases.

In particular, there is a problem that the oil contamination in the workplace because the element and the drain core must be removed and remounted when the element is replaced.

Accordingly, an object of the present invention is to integrally form an element and a drain core coupled inside the oil filter housing, and to couple the drain core to the lower part of the element, when the element and the drain core are coupled to the oil filter housing. Since it is coupled to the element can be easily and accurately coupled to the oil filter housing, to provide an automotive drain core integrated oil filter that can effectively solve the problem of oil leakage.

In addition, since the gap between the element and the drain core does not occur because the element and the drain core are integrally formed, it is possible to effectively solve the problem of separately providing an expensive fiber material for enhancing airtightness on the upper and lower parts of the element. Since the element and the drain core are integrally formed, it is necessary to provide an automotive drain core integrated oil filter that effectively solves the problem of oil contamination due to the fact that only the element needs to be replaced when the element is replaced.

In addition, since it is often cumbersome to replace the sealing that is mounted on the drain core, there is a possibility of oil leakage related quality problem by using it as it is, but in the case of the present invention, a new sealing is provided as assembled on the element to solve the oil leakage quality problem. There is a characteristic.

The present invention is an automotive oil filter comprising an oil filter element and a drain core for filtering foreign substances generated during engine combustion of an automobile. The oil filter element is formed in a horizontally long cylindrical shape to filter contaminated oil sent from an engine. An element having a cylindrical oil passage formed therein; and an upper cap provided on the upper portion of the element, having an upper oil hole formed in the center thereof, and a cap coupling portion formed adjacent to the upper oil hole.

In addition, a lower oil hole is formed in the center of the element, and a drain core having a diameter smaller than the oil passage is formed in a long cylindrical shape, and one or more grooves are formed on the outer circumferential surface of the drain core, A lower cap installed to prevent oil leakage by installing an O-ring; coupled to the cap coupling portion of the upper cap, and a cylindrical bypass portion formed at the lower portion is fitted into the oil passage and fixed, and bypassed into the bypass portion. And a bypass cap having a pass valve.

In particular, in the oil passage formed inside the element, a cylindrical filter pillar formed in the form of a lattice is provided between the upper cap and the lower cap to prevent the element of the oil filter from being deformed by hydraulic pressure, and the lower portion coupled with the element. The purpose of the present invention can be achieved by forming a reinforcing part formed thicker than the thickness of the lower cap in the coupling part connected to the drain core in the cap, thereby preventing the coupling part of the lower cap and the drain core from being broken by hydraulic pressure. will be.

In the present invention, the element and the drain core are integrally formed in the oil filter housing so that when the element is coupled to the oil filter housing, the element and the drain core are integrally coupled to the oil filter housing so that the element can be easily and accurately. It can be coupled to the oil filter housing, it is effective to reduce the maintenance cost of the vehicle by preventing the engine failure due to the oil leakage occurs when the element and the drain core is incorrectly assembled in the oil filter housing.

In addition, since the element and the drain core are integrally formed, an expensive fiber material for enhancing airtightness is not required on the upper and lower parts of the element, thereby reducing the production cost of the product and simplifying the assembly process. .

In addition, the replacement process is cumbersome, so the frequently reused seals are always replaced with new ones, which prevents leakage-related quality problems and prevents the filtration function when ordinary elements are inserted into the protrusions on the bottom of the housing. There is also the effect of increasing the filtration efficiency is also prevented the problem of space.
