Description
본 고안은 엔진윤활용 오일을 여과하여 금속등 마모된 찌꺼기나 카본 등 이물질을 제거하는 오일필터에 관한 것으로, 특히 여과지의 오손시에 오일을 바이패스 시키는 바이패스 구조에 관한 것이다.The present invention relates to an oil filter for filtering engine lubrication oil to remove worn residues such as metals and foreign substances such as carbon, and more particularly, to a bypass structure for bypassing oil when a filter paper is damaged.
오일펌프에서 토출된 엔진오일은 엔진내부를 윤활하고 다시 오일팬으로 되돌려 보낸다.The engine oil discharged from the oil pump lubricates the engine and sends it back to the oil pan.
엔진속을 순환하는 엔진오일은 크랭크 축이나 캠축의 윤활, 냉각과 동시에 엔진내부의 금속가루나 연소잔류물 등의 청정작용도 가지고 있다.The engine oil circulating in the engine has the lubrication and cooling of the crankshaft and the camshaft as well as the cleaning of metal powder and combustion residues in the engine.
이와 같이 엔진내부를 순환하면서 오일속에 섞이게 된 불순물을 제거하는 것이 바로 오일여과기다.In this way, it is an oil filter that removes impurities mixed in the oil while circulating inside the engine.
이 오일여과기는 일반적으로 오일펌프의 직후에 설치되어 있으며 오일펄프에서 토출되는 엔진오일은 전부 여과기를 통과하여 여과기를 통과한 오일이 엔진내를 여과하는 것이며, 오일여과기는 대부분 내부에 여과지를 집어 넣는 일체식의 카트리지 타입이며, 이 여과지에 의해 불순물이 제거된다.This oil filter is generally installed immediately after the oil pump, and all the engine oil discharged from the oil pulp passes through the filter and the oil passing through the filter filters the inside of the engine, and most of the oil filters put the filter paper inside. It is an integrated cartridge type, and impurities are removed by this filter paper.
이와 같은 여과기에는 도 2의 도시와 같이 여과지(4)의 하부 공간에 여과지를 통과하는 공간에 밸브(8)를 스프링(7)으로 탄설한 릴리프밸브(6)를 설치하여 여과지(4)가 오손되어 투과저항이 증대되어 여과기의 내압이 높아지게 되면 밸브가 열려 엔진오일을 바이패스시켜 엔진 내부를 윤활하는 것이다.In such a filter, as shown in FIG. 2, a relief valve 6 is installed in the lower space of the filter paper 4 through the filter paper in the space passing through the filter paper, and the filter paper 4 is damaged. When the permeation resistance is increased to increase the internal pressure of the filter, the valve is opened to bypass the engine oil to lubricate the engine.
그러나 전기한 오일여과기는 자동차의 시동시에 일시적으로 오일의 유입압력이 배출압력보다 높게되어 여과지의 기능이 정상임에도 불구하고 그 차압에 의해 릴리이프 밸브(6)가 순간적으로 작동하여 오픈됨으로서 그 여과기능이 상실되는 문제가 있다.The oil filter, however, is temporarily filtered when the relief valve 6 is opened and operated by the differential pressure even though the function of the filter paper is normal because the oil inlet pressure is temporarily higher than the discharge pressure at the start of the vehicle. There is a problem that the function is lost.
본 고안은 오일여과기 있어서, 전기한 바와 같은 문제점을 제거코저 릴리프 밸브에 솔레노이드를 장착하여 자동차의 시동시에는 솔레노이드이 전자력에 의해 오일의 차압에도 릴리프밸브가 작동되지 않고 있다가 평상시에는 솔레노이드 밸브가 OFF되어 스프링의 탄발력으로만 릴리프밸브가 작동되어 기존의 경우와 같이 바이패스 역할을 하게 한 오일여과기의 바이패스 구조를 제공함에 그 목적이 있다.The present invention eliminates the problems described above, and the solenoid is mounted on the nose relief valve so that the solenoid valve is not operated by the electromagnetic force even when the vehicle is started. The purpose of the present invention is to provide a bypass structure of the oil filter, in which the relief valve is operated only by the spring force of the spring, thereby acting as a bypass.

전기한 목적을 이루기 위한 기술수단으로서 여과지가 내입된 여과통의 하측 중앙에 릴리프 밸브를 장착하되 이에 솔레노이드를 부착하고 이를 시동 전원과 연결시켜 자동차의 시동시에 솔레노이드가 작동되게 하여 릴리프 밸브의 작동을 차단되게 한 오일여과기의 바이패스 구조를 제공한다.As a technical means for achieving the above-mentioned purpose, a relief valve should be installed in the lower center of the filter container into which the filter paper is inserted. To provide a bypass structure for the oil filter.
이하, 본 고안의 실시예를 첨부 도면에 의하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail by the accompanying drawings.
도 1은 본 고안의 여과기를 단면표시한 것이다.1 is a cross-sectional view of the filter of the present invention.
여과기는 여과외통(1)과, 여과내통(2)으로 구분 형성하고, 그 내측 공간부(3)에 여과지(4)를 내입 장착한다.The filter is divided into a filtration outer cylinder 1 and a filtration inner cylinder 2, and the filter paper 4 is inserted in the inner space 3 of the filter.
전기한 여과내통(2)의 주면에는 통공(5)(5')을 형성하고, 그 하측부에 릴리프 밸브(6)을 장착하여 스프링(7)으로 탄설된 밸브(8)에 솔레노이드(9)를 장착한다.A through hole 5, 5 'is formed in the main surface of the aforementioned inner filtration cylinder 2, and a relief valve 6 is attached to the lower side thereof, so that the solenoid 9 is connected to the valve 8, which is loaded with a spring 7. To be fitted.
솔레노이드(9)는 자동차 시동전원과 연결한다.The solenoid 9 is connected to the vehicle starting power source.
도면 중 미설명부호 10은 오일유입공간, 11은 하부공간, 12는 결합구이다.In the drawings, reference numeral 10 denotes an oil inflow space, 11 a lower space, and 12 a coupling hole.
본 고안의 오일여과기를 오일펌프의 직후에 설치하게 되면 오일펌프에서 토출되는 오일의 여과기를 통과하면서 엔진 내부를 포함하여 크랭크축이나 캠축을 윤활하면서 발생하는 오일내의 금속가루나 연소잔류물이 여과기를 통과하면서 여과외통(1)과 여과내통(2) 사이에 내입 장착된 여과지(4)에 의해 여과되어 통공(5)(5')을 통과한 청전오일을 각 부품에 공급할 수 있다.When the oil filter of the present invention is installed immediately after the oil pump, metal powder or combustion residues in the oil generated while lubricating the crankshaft or camshaft including the inside of the engine while passing through the filter of oil discharged from the oil pump pass through the filter. While being filtered by the filter paper 4 interposed between the filtration outer cylinder 1 and the filtration inner cylinder 2 and passing through the through holes 5 and 5 ', it is possible to supply the cleansing oil to each part.
여기에서 자동차 시동을 걸 시에 일시적으로 오일의 유입압력이 배출압력보다 높아 지더라도 시동시에 솔레노이드(9)가 잠시동안 작동되어 릴리프밸브(6)내의 밸브체(8)를 지지하여 줌으로써 릴리프밸브(6)가 열리지 않아 순간적이라도 여과기의 기능을 상실하지 않고 계속적으로 여과기의 역할을 수행한다.Here, even when the oil inlet pressure is higher than the discharge pressure temporarily when starting the car, the solenoid 9 is operated for a while at the start to support the valve body 8 in the relief valve 6 to release the relief valve. (6) does not open and does not lose the function of the filter even at the moment.
또 시동후의 평상 작동시에는 다시 솔레노이드(9)가 OFF되어 릴리프밸브(6)의 밸브체(8)가 스프링(7)의 탄발력으로만 지지되므로서 평상시에는 하부공간(11)을 차단하여 여과지(4)로만 통과 여과되게 하다가 여과지에 불순물이 많이 흡착되어 있어 투과저항이 발생하는 경우에 그 여과기의 내압이 스프링(7)의 탄발력을 넘어서게 되어 그 밸브체(8)를 열게 되어 바이패스 시키는 것이다.In addition, the solenoid 9 is turned off during normal operation after starting, and the valve body 8 of the relief valve 6 is supported only by the spring force of the spring 7, so that the lower space 11 is normally cut off to filter the filter paper. (4) is passed through, but when the impurities are adsorbed on the filter paper and the permeation resistance occurs, the internal pressure of the filter exceeds the elasticity of the spring (7) to open the valve body (8) to bypass will be.
이상과 같이 본 고안은 엔진윤활유 오일을 여과하는 여과기에 있어서, 그 바이패스용 릴리프밸브에 솔레노이드를 장착하므로서 평상시에 통상적인 여과기능을 수행하면서도 자동차의 시동시에 차압이 발생하더라도 여과기능이 상실되지 않고 여과기능을 계속적으로 수행되게 한 효과가 있다.As described above, the present invention is a filter for filtering engine lubricating oil, and the solenoid is attached to the bypass relief valve so that the filtration function is not lost even when the differential pressure occurs at the start of the vehicle while performing the usual filtration function. There is an effect that the filtration function is continuously performed without.
