Description

자동차용 윤활유 여과기{Engine oil filter for automobil}[0001] The present invention relates to an engine oil filter for automobile,

본 발명의 목적은 윤활유의 흐름이 적절히 유지되는 상태에서 윤활유에 섞여 유동되는 이물질을 효과적으로 제거하며, 이물질을 발생시키지 않는 자동차용 윤활유 여과기를 제공하는데 있다.It is an object of the present invention to provide a lubricating oil filter for automobiles which effectively removes foreign matter mixed with lubricating oil while the flow of lubricating oil is properly maintained and does not generate foreign matter.

본 발명은 자동차 엔진에 사용되는 윤활유에 썩인 이물질을 제거하는 자동차용 윤활유 여과기에 관한 것이다.TECHNICAL FIELD The present invention relates to a lubricating oil filter for automobiles which removes impurities from a lubricating oil used in an automobile engine.

일반적으로, 자동차 엔진에는 엔진의 작동을 원활하게 하고 수명을 연장시키기 위해 운동 마찰부분에 윤활유를 공급하는 윤활장치가 설치된다. 윤활장치에는 엔진의 접동부에서 발생되는 쇳가루, 연소에 의해 발생된 카본 등의 이물질을 여과하여 윤활유를 항상 깨끗한 상태로 유지시키는 윤활유 여과기가 설치된다.Generally, an automobile engine is provided with a lubrication device for supplying lubricating oil to a dynamic friction portion in order to smooth the operation of the engine and prolong its service life. The lubrication apparatus is provided with a lubricant filter for filtering out foreign matter such as carbon dust generated in the sliding portion of the engine and carbon generated by the combustion and always keeping the lubricant oil in a clean state.

도 1을 참조하면, 윤활유 여과기가 사용되는 윤활장치에는 바이패스밸브(10)가 설치된다. 이 바이패스밸브(10)는 여과기(20)가 윤활유의 흐름을 방해하여 여과기 입구(21)와 출구(22) 사이에 심한 압력차가 발생되면 자동적으로 열려 여과되지 않은 윤활유가 화살표 A방향으로 엔진의 접동부로 유입되도록 하는 장치이다.Referring to Fig. 1, a bypass valve 10 is installed in a lubrication apparatus in which a lubricant filter is used. This bypass valve 10 is automatically opened when the filter 20 interferes with the flow of the lubricant and a significant pressure difference between the filter inlet 21 and the outlet 22 causes the unfiltered lubricant to flow in the direction of the arrow A To the sliding portion.

자동차의 엔진에는 주로 엘리먼트와 케이스가 일체로 된 일체식이면서, 오일펌프에서 압송된 윤활유 전부를 오일 여과기에서 여과한 다음 각부분으로 공급하는 전류식 윤활유 여과기 사용된다.In the automobile engine, a current type lubricating oil filter is used in which the entire element and the case are integrally formed, and all the lubricating oil fed from the oil pump is filtered through an oil filter and supplied to each part.

도 1은 종래의 일체식이면서 전류식 윤활유 여과기를 도시한 반단면도이다. 도시된 바와 같이, 윤활유 여과기(20)는 금속으로 만들어진 케이스(23)와, 이 케이스(23) 내부에 설치되는 엘리먼트(24)와, 케이스(23)와 엘리먼트(24) 사이에 설치되어 엘리먼트(24)를 케이스(23)에 밀착시키는 스프링(27)을 포함하여 구성된다.1 is a half sectional view of a conventional integrated and current lubricating oil filter. As shown in the figure, the lubricant filter 20 includes a case 23 made of metal, an element 24 provided inside the case 23, a case 23 provided between the case 23 and the element 24, 24 to the case 23 in a state in which they are in close contact with each other.

상기 종래의 엘리먼트(24)는 부직포로 만들어진 여과망(25)과, 이 여과망(25)을 지지하는 보강망(26)을 포함하여 구성된다. 부직포로 만들어진 여과망(25)은 이물질이 쌓이면 윤활유를 원활하게 여과하지 못하는 문제점이 있다. 즉, 상기 부직포에 형성된 윤활유 통로는 이물질에 의하여 쉽게 좁아져 윤활유의 흐름을 저하시킨다.The conventional element 24 includes a filter net 25 made of a nonwoven fabric and a reinforcing net 26 for supporting the filter net 25. The filter net 25 made of a nonwoven fabric has a problem in that the lubricant can not be smoothly filtered when foreign matter is accumulated. That is, the lubricant passage formed in the nonwoven fabric is easily narrowed by the foreign substance, thereby reducing the flow of the lubricant.

윤활유의 흐름이 저하되면 첫째, 여과기 입구(21)와 출구(22) 사이에 심한 압력차가 발생되며, 이 압력차에 의하여 상술한 바이패스밸브(10)가 열여 여과되지 않은 오일이 직접 접동부에 공급되거나, 심한 압력차로 인하여 부직포로 만들어진 여과망(25)이 손상되어 여과되지 않은 윤활유가 엔진의 접동부에 직접 공급되는 문제점이 있다. 둘째, 부직포로 만들어진 여과망(25)이 손상되면서 부직포에서 떨어진 이물질이 윤활유에 섞여 엔진의 접동부로 공급되는 문제점이 있다.When the flow of the lubricating oil is lowered, a significant pressure difference is generated between the filter inlet 21 and the outlet 22, and the bypass valve 10 described above is opened by the pressure difference so that unfiltered oil flows directly to the sliding portion Or the filter net 25 made of non-woven fabric is damaged due to a severe pressure difference, and the unfiltered lubricant is supplied directly to the sliding portion of the engine. Second, as the filter net 25 made of nonwoven fabric is damaged, foreign matter separated from the nonwoven fabric is mixed with lubricating oil and supplied to the sliding portion of the engine.

윤활유의 흐름이 적절히 유지되는 상태에서 윤활유에 섞여 유동되는 이물질을 효과적으로 제거하며, 이물질을 발생시키지 않는 윤활유 여과기를 구현하는데 있다.The present invention is to provide a lubricant filter which effectively removes impurities flowing in a lubricating oil while the flow of the lubricating oil is properly maintained and does not generate foreign matter.

이하 첨부된 도면을 참조하면서 본 발명에 따른 자동차용 윤활유 여과기의 바람직한 실시예를 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a lubricating oil filter for a motor vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 일체식이면서 전류식 윤활유 여과기를 도시한 반단면도이다. 도시된 바와 같이, 윤활유 여과기(30)는 금속으로 만들어진 케이스(35)와, 이 케이스(35) 내부에 설치되는 엘리먼트(36)와, 케이스(35)와 엘리먼트(36) 사이에 설치되어 엘리먼트(36)를 케이스(35)에 밀착시키는 스프링(38)과, 케이스(35)와 엘리먼트(36) 사이에 설치되는 자석(37)을 포함하여 구성된다.Figure 2 is a half sectional view of an integrated, current lubricating oil filter according to the present invention. As shown in the figure, the lubricant filter 30 includes a case 35 made of metal, an element 36 installed inside the case 35, a case 35 provided between the case 35 and the element 36, And a magnet 37 provided between the case 35 and the element 36. The spring 36 is attached to the casing 35 by a spring 38. The spring 36 is attached to the case 35,

상기 엘리먼트(36)는 1차 여과망(31), 1차 보강망(32), 2차 여과망(33), 2차 보강망(34)을 포함하여 구성되는 것이 바람직하다. 1차 여과망(31) 및 2차 여과망(33)은 윤활유와 섞여 이동되는 이물질을 여과하는 역할을 하며, 1,2차 보강망(32,34)은 1,2차 여과망(31,33)을 지지하는 역할을 한다.The element 36 preferably comprises a primary filter network 31, a primary reinforcement network 32, a secondary filter network 33, and a secondary reinforcement network 34. The first and second filter nets 31 and 33 serve to filter the foreign matter mixed with the lubricating oil and the first and second reinforcement nets 32 and 34 are connected to the first and second filter nets 31 and 33, .

상기 1차 여과망(31) 및 2차 여과망(33)은 100매쉬∼300매쉬의 강철망으로 만들어질 수 있으나, 바람직하게는 120매쉬의 강철망으로 만들어지는 것이 바람직하다. 이는, 100매쉬 이하의 강철 여과망은 통유성은 좋으나 미세한 철분을 여과할 수 없는 문제점이 있으며, 300매쉬 이상의 강철 여과망은 미세한 철분을 여과할 수 있으나 통유성이 나쁜 문제점이 있기 때문이다.The primary filtering network 31 and the secondary filtering network 33 may be made of steel mesh of 100 mesh to 300 mesh, preferably 120 mesh steel mesh. This is because the steel filter net of 100 mesh or less has a problem in that it can not filter fine iron particles although the flowability is good, and the steel filter net of 300 mesh or more can filter fine iron particles, but has poor flowability.

이와 같은 미세한 강철망이 사용된 윤활유 여과기는 통유성이 좋아 오일펌프에서 공급된 윤활유를 여과하여 충분한 량의 여과된 윤활유를 엔진의 접동부에 제공할 수 있다. 또한 강철망에는 미세한 철분이 효과적으로 부착되어 종래의 부직포보다 여과 성능이 좋으며, 여과기 입출구에 심한 압력차가 발생되어도 강철 여과망은 손상되지 않으며, 자체적 이물질을 발생하지 않는다.The lubricating oil filter using such a fine steel mesh is excellent in flowability and can filter the lubricating oil supplied from the oil pump to provide a sufficient amount of filtered lubricating oil to the sliding portion of the engine. In addition, fine iron powder adheres effectively to the steel net, so that the filtration performance is better than that of the conventional nonwoven fabric. Even if there is a serious pressure difference at the inlet and outlet of the filter, the steel filter net is not damaged and does not generate its own foreign matter.

상기 자석(37)은 1000가우스 이상의 영구자석으로 되는 것이 바람직하며, 도 2에 도시된 바와 같이 스프링(38)과 엘리먼트(36) 사이에 설치될 수 있으며, 도 3에 도시된 바와 같이 케이스(35) 내면에 설치될 수 있다.The magnet 37 is preferably a permanent magnet of 1000 gauss or more and may be installed between the spring 38 and the element 36 as shown in FIG. ). ≪ / RTI >

이와 같은 강력한 자석(37)은 다음과 같은 2가지 역할을 한다. 첫째, 윤활유를 따라 유동되는 미세한 철분을 윤활유로부터 분리시키고, 상기 강철 여과망(31,33)을 자화시켜 상기 미세한 철분이 부착될 수 있도록 돕는 역할을 한다. 둘째, 상기 자석의 강력한 자력은 윤활유에 첨가된 촉매제를 안전하게 결합될 수 있도록 조력하여 윤활유의 수명을 연장시키는 역할을 한다.Such a strong magnet 37 plays two roles as follows. First, the fine iron powder flowing along the lubricating oil is separated from the lubricating oil, and the iron filter net 31 and 33 is magnetized to help the fine iron powder adhere. Second, the strong magnetic force of the magnet serves to secure the catalyst added to the lubricating oil so as to securely bond the lubricating oil, thereby extending the service life of the lubricating oil.

첨부된 참조 도면에 의해 설명된 본 발명의 바람직한 실시예는 단지 일 실시예에 불과하다. 당해 기술 분야에 통상의 지식을 가진 자라면 본 발명의 바람직한 실시예를 충분히 이해하여 유사한 형태의 윤활유 여과기를 구현할 수 있을 것이다. 따라서 본 발명의 진정한 기술적 보호 범위는 본 발명의 기술적 사상에 의한 특허청구범위에 의해 정해져야 할 것이다.The preferred embodiments of the invention described by the attached reference figures are only one embodiment. Those skilled in the art will be able to implement a similar type of lubricant filter with a thorough understanding of the preferred embodiments of the present invention. Accordingly, the true scope of the present invention should be determined by the scope of claims of the present invention.

본 발명에 따른 자동차용 윤활유 여과기는 윤활유의 흐름이 적절히 유지되는 상태에서 윤활유에 섞여 유동되는 이물질을 효과적으로 제거하며, 이물질을 발생시키지 않는다.The lubricating oil filter for an automobile according to the present invention effectively removes foreign matter flowing in the lubricating oil while the flow of the lubricating oil is properly maintained and does not generate foreign matter.
