자동차용 윤활유 여과기{Engine oil filter for automobil}Automotive oil filter {Engine oil filter for automobil}

본 발명은 자동차 엔진에 사용되는 윤활유에 섞인 이물질을 제거하는 자동차용 윤활유 여과기에 관한 것이다.The present invention relates to an automotive lubricant filter for removing foreign substances mixed with lubricants used in automobile engines.

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, a lubricator is installed in an automobile engine to supply lubricating oil to a moving friction part in order to smoothly operate the engine and extend its life. The lubrication device is provided with a lubricating oil filter which filters foreign substances such as powder generated from the sliding part of the engine, carbon generated by combustion, and keeps the lubricating oil clean at all times.

자동차의 엔진에는 주로 엘리먼트와 케이스가 일체로 된 일체식이면서 오일펌프에서 압송된 윤활유 전부를 오일 여과기에서 여과한 다음 각 부분으로 공급하는 전류식 윤활유 여과기가 사용된다.In the engine of a vehicle, a current type lubricant filter is used, in which an element and a case are integrated, and all of the lubricant pumped from the oil pump is filtered through an oil filter and then supplied to each part.

도 1은 종래의 일체식이면서 전류식 윤활유 여과기를 도시한 반단면도이다. 도시된 바와 같이, 윤활유 여과기는 금속으로 만들어진 케이스(10)와, 이 케이스(10) 내부에 설치되는 엘리먼트(20)와, 케이스(10)와 엘리먼트(20) 사이에 설치되어 엘리먼트(20)를 케이스(10)에 밀착시키는 스프링(30)을 포함하여 구성된다.1 is a half sectional view showing a conventional integrated and current lubricating oil filter. As shown, the lubricant filter is provided between a case 10 made of metal, an element 20 installed inside the case 10, and a case 20 between the case 10 and the element 20 so as to move the element 20. It is configured to include a spring 30 in close contact with the case 10.

상기 케이스(10)는 덮개(11), 보강판(12), 시밍판(13)을 포함하여 구성되며, 보강판(12)에는 윤활유가 유입되는 유입구멍914)과 윤활유가 배출되는 배출구멍(15)이 형성되어 있으며, 보강판(12)과 엘리먼트(20) 사이에는 상기 유입구멍(14)으로 유입되는 윤활유의 역류를 방지하는 체크밸브(16)가 설치되어 있다.The case 10 includes a cover 11, a reinforcement plate 12, and a seaming plate 13, and the reinforcement plate 12 includes an inlet hole 914 through which lubricant is introduced and a discharge hole through which the lubricant is discharged ( 15 is formed, and a check valve 16 is provided between the reinforcing plate 12 and the element 20 to prevent the backflow of the lubricating oil flowing into the inlet 14.

상기 엘리먼트(20)는 상부캡(21), 하부캡(24), 여과망(22), 보강망(23)을 포함하여 구성된다. 상부캡(21)은 상기 보강판(12)에 접촉되어 설치되며, 하부캡(24)은 스프링(30)에 지지된다. 그리고, 상부캡(21)과 하부캡(24) 사이에는 부직포로 만들어진 여과망(22)과, 이 여과망(22)을 지지하는 보강망(23)이 설치된다.The element 20 comprises an upper cap 21, a lower cap 24, a filtering net 22, and a reinforcing net 23. The upper cap 21 is installed in contact with the reinforcing plate 12, the lower cap 24 is supported by the spring (30). And, between the upper cap 21 and the lower cap 24, a filtering net 22 made of a nonwoven fabric, and a reinforcing net 23 for supporting the filtering net 22 is provided.

부직포로 만들어진 여과망(22)은 이물질이 쌓이면 윤활유가 원활하게 여과되지 못하는 문제점을 가지고 있다. 즉, 상기 부직포에 형성된 윤활유 통로는 이물질에 의하여 쉽게 좁아져 윤활유의 흐름을 저하시킨다. 그리고, 부직포로 만들어진 여과망(22)이 쉽게 손상되며 부직포에서 떨어진 이물질이 윤활유에 섞여 엔진의 접동부로 공급되는 문제점이 발생된다. 또한, 이물질에 의하여 윤활유의 흐름이 저하되면 윤활유 유입구(14)와 배출구(15) 사이에 심한 압력차가 발생되어 바이패스밸브(1)가 열어 여과되지 않은 오일이 직접 접동부에 공급되는 문제점이 발생된다.The filter net 22 made of a nonwoven fabric has a problem in that lubricating oil is not filtered smoothly when foreign matter is accumulated. That is, the lubricating oil passage formed in the nonwoven fabric is easily narrowed by foreign matter, thereby reducing the flow of lubricating oil. In addition, the filter network 22 made of a nonwoven fabric is easily damaged, and foreign matter dropped from the nonwoven fabric is mixed with the lubricating oil and is supplied to the sliding part of the engine. In addition, when the flow of lubricating oil is deteriorated by foreign matters, a severe pressure difference is generated between the lubricating oil inlet 14 and the outlet 15 so that the bypass valve 1 is opened to supply unfiltered oil directly to the sliding part. do.

따라서, 본 발명의 첫 번째 목적은, 윤활유의 흐름이 적절히 유지되는 상태에서 윤활유에 섞여 유동되는 이물질을 효과적으로 제거하며 이물질을 발생시키지 않는 윤활유 여과기를 제공하는데 있으며, 본 발명의 두 번째 목적은 윤활유 여과기의 부품수를 줄여 생산성을 향상시킬 수 있는 윤활유 여과기를 제공하는데 있다.Accordingly, a first object of the present invention is to provide a lubricant filter that effectively removes foreign substances mixed with lubricant in a state in which the flow of lubricant is properly maintained and does not generate foreign substances, and a second object of the present invention is a lubricant filter. It is to provide a lubricant filter that can improve the productivity by reducing the number of parts.
