일반적으로 오일필터(Oil fiter)는 윤활 화로 내에 설치되어 오일에 혼합된 먼지, 카본, 금속분말, 산화 생성물 등을 제거하는 역할을 한다.In general, the oil filter (Oil fiter) is installed in the lubrication furnace serves to remove dust, carbon, metal powder, oxidation products, etc. mixed in the oil.

그리고, 오일 필터는 프러스 케이스에 부착되고, 일부 엔진애서는 실린더 블록에 설치되기도 한다.And, the oil filter is attached to the pruss case, and some engines are installed in the cylinder block.

도 1에 도시된 바와 같이 종래에는 그 하부에 오일펌프(미도시) 쪽과 연결되는 인입공(11)과, 그 중앙에 엔진쪽과 연결되어 윤활 작용을 할 수 있도록 하는 인출공(12)을 가지는 하우징(10)이 프런트 케이스(미도시)의 일측에 설치된다.As shown in FIG. 1, conventionally, an inlet hole 11 connected to an oil pump (not shown) is connected to a lower part thereof, and an outlet hole 12 connected to an engine side in the center thereof to perform lubrication. The housing 10 is installed on one side of the front case (not shown).

상기 인입공(11)으로 들어오는 엔진오일을 여과 할 수 있도록 상기 하우징(10) 내측에 여과지(13)가 설치된다. 상기 여과지(13)를 거쳐 여과된 오일을 상기 인출공으로 보내질 수 있도록 다수개의 누출공(15)을 가지며 그 하부에 배출공(16)을 갖는 여과지 고정부재(14)가 상기 여과지(13) 내측에 설치된다.The filter paper 13 is installed inside the housing 10 to filter the engine oil entering the inlet 11. A filter paper fixing member 14 having a plurality of leak holes 15 and a discharge hole 16 at a lower portion thereof so that the oil filtered through the filter paper 13 can be sent to the outlet hole is provided inside the filter paper 13. Is installed.

상기 여과지(13)가 막혔을 때 여과되지 않은 오일을 공급할 수 있도록 상기 여과지 고정부재(14) 상부와 상기 하우징(10)의 내측에 바이패스밸브(17)가 설치된다. 상기 바이패스밸브(17)를 지지하는 탄성부재(18)가 상기 하우징(10) 내측 상부와 상기 바이패스밸브(17) 사이에 설치된다.When the filter paper 13 is blocked, a bypass valve 17 is installed on the upper part of the filter paper fixing member 14 and the inside of the housing 10 to supply unfiltered oil. An elastic member 18 for supporting the bypass valve 17 is installed between the upper portion of the housing 10 and the bypass valve 17.

상기와 같이 구성된 종래의 엔진오일 여과용 오일필터의 작용을 살펴보면 다음과 같다.Looking at the action of the conventional oil filter for engine oil filtration configured as described above are as follows.

오일 펌프에 의해 인입공(11)을 통해 엔진오일이 유입되면, 상기 하우징(10)의 내측에 설치되어 있는 여과지(13)에 의해 여과된다. 상기 여과지 고정부재(14)에 형성되어 있는 누출공(15)을 통해 여과된 오일이 공급되고, 상기 여과지 고정부재(14)의 내측으로 모여진 오일이 그 하부에 형성된 배출공(16)과 상기 하우징(10)의 하부에 형성되어 있는 인출공(12)을 통해 엔진의 윤할통로(미도시)로 오일이 공급된다.When the engine oil flows through the inlet hole 11 by the oil pump, it is filtered by the filter paper 13 installed inside the housing 10. The filtered oil is supplied through the leak hole 15 formed in the filter paper fixing member 14, and the oil collected inside the filter paper fixing member 14 is formed at the lower portion of the discharge hole 16 and the housing. The oil is supplied to the lubrication passage (not shown) of the engine through the drawing hole 12 formed in the lower portion of the engine 10.

그러나 상기 하우징(10) 내측에 여과지(13)를 설치할 시에 그 간격이 좁혀지거나 반대로 넓혀지게 되고, 상기 하우징(10) 내측으로 공급되는 오일압이 높으면 여과지가 쏠리게되어 정화효율이 저감되는 문제점이 있었다.However, when the filter paper 13 is installed inside the housing 10, the gap is narrowed or widened to the contrary, and when the oil pressure supplied to the housing 10 is high, the filter paper is concentrated to reduce the purification efficiency. there was.

따라서 상기한 문제점을 해결하기 위한 본 발명은 오일 필터링용 여과지의 쏠림방지 및 오일의 냉각 효과를 극대화하기 위한 엔진오일 여과용 오일필터를 제공하는데 그 목적이 있다.Therefore, an object of the present invention for solving the above problems is to provide an oil filter for filtering engine oil for maximizing the anti-tip of the filter paper for oil filtering and the cooling effect of the oil.

도 2 및 도 3에 도시한 바와 같이 본 발명에는 프런트 케이스에 설치되며 하우징(10)이 구비된다. 상기 하우징(10)에는 그 하부에 엔진오일이 인입될 수 있도록 인입공(11)이 형성되고, 그 하부 중앙에는 여과된 오일이 인출될 수 있도록 인출공(12)이 형성된다.As shown in FIG. 2 and FIG. 3, the present invention is installed in the front case and has a housing 10. In the housing 10, an inlet hole 11 is formed in the lower portion thereof so that the engine oil can be introduced therein, and an outlet hole 12 is formed in the lower center thereof so that the filtered oil can be drawn out.

이물질이 포함된 오일을 여과할 수 있도록 여과지(13)가 상기 하우징(10) 내측에 설치된다. 상기 여과된 오일이 엔진으로 공급될 수 있도록 상기 여과지(13) 내측에 여과지 고정부재(14)가 설치된다. 상기 여과된 오일이 엔진으로 공급될 수 있도록 상기 여과지 고정부재(14)의 외주연에 다수개의 누출공(15)이 형성된다.The filter paper 13 is installed inside the housing 10 to filter the oil containing the foreign matter. The filter paper fixing member 14 is installed inside the filter paper 13 to supply the filtered oil to the engine. A plurality of leak holes 15 are formed on the outer circumference of the filter paper fixing member 14 so that the filtered oil can be supplied to the engine.

상기 여과지(13)가 막혔을 시에 여과되지 않은 오일을 엔진으로 공급할 수 있도록 상기 하우징(10) 내측 상부와 상기 여과지 고정부재(14) 상부 사이에 바이패스밸브(17)가 설치된다. 상기 바이패스밸브(17)를 지지하기 위하여 그 상부에 탄성부재(18)가 설치된다.The bypass valve 17 is installed between the upper part of the housing 10 and the upper part of the filter paper fixing member 14 to supply the unfiltered oil to the engine when the filter paper 13 is blocked. An elastic member 18 is installed on an upper portion of the bypass valve 17 to support the bypass valve 17.

상기 여과지(13)의 쏠림을 방지함과 동시에 오일의 온도를 저하시키기 위한 발열수단이 상기 하우징(10)의 내벽과 상기 여과지(13) 사이에 설치된다.A heating means for preventing the filter paper 13 from being pulled and lowering the temperature of the oil is provided between the inner wall of the housing 10 and the filter paper 13.

상기 발열수단은 오일의 온도를 저하시킬 수 있도록 그 소정 부위에 돌출부(21)를 갖는 발열부재(20)가 상기 하우징(10) 내측에 설치된다. 상기 발열부재(20)와 동일한 작용을 하며 오일의 온도를 확실하게 저하시기 위하여 열전도가 우수한 발열액(22)이 상기 돌출부(21) 내측과 상기 하우징(10) 내벽 사이에 주입된다.The heat generating means has a heat generating member 20 having a protrusion 21 at a predetermined portion thereof so as to lower the temperature of the oil is installed inside the housing 10. An exothermic liquid 22 having excellent thermal conductivity is injected between the inside of the protrusion 21 and the inner wall of the housing 10 in order to reliably lower the temperature of the oil while acting the same as the heat generating member 20.

이하 상기와 같은 구성을 가지는 본 발명에 의한 엔진오일 여과용 오일필터의 작용을 설명하면 다음과 같다.Hereinafter will be described the operation of the oil filter for engine oil filtration according to the present invention having the configuration as described above.

하우징(10)의 하부에 형성되어 있는 인입공을 통해 오잎펌프에 의해 공급되면, 상기 오일은 상기 여과지(13)에 의해 이물질이 걸러지고, 이물질이 걸러진 오일이 여과지 고정부재(14)에 형성되어 있는 누출공(15)을 통해 그 내부로 모이게 된다.When the oil is supplied by the oil pump through the inlet hole formed in the lower portion of the housing 10, the foreign matter is filtered by the filter paper 13, the oil filtered foreign matter is formed in the filter paper fixing member 14 Through the leaking hole 15 therein.

상기 여과지 고정부재(14)의 내부로 모여지는 상기 하우징(10)의 하부에 형성되어 있는 인출공(12)을 통해 엔진의 블록으로 공급되는 데, 상기 오일은 그 온도가 저하된 상태로 공급된다.It is supplied to the block of the engine through the outlet hole 12 formed in the lower portion of the housing 10 collected inside the filter paper fixing member 14, the oil is supplied in a state where the temperature is lowered .

상기 오일이 온도가 저하되는 것을 살펴보면, 하우징(10) 내측과 여과지(13) 사이에 설치되어 있는 발열부재(20)에 의해 1차적으로 오일의 온도를 저하시키고, 발열부재(20)에 형성되어 있는 돌출부(21)에 주입되어 있는 발열액(22)에 의해 2차적으로 온도를 저하시켜 엔진으로 공급되는 오일의 온도는 상다히 저하된 상태로 공급된다.When the oil is lowered in temperature, the temperature of the oil is primarily lowered by the heat generating member 20 installed between the housing 10 and the filter paper 13, and is formed on the heat generating member 20. The temperature of the oil supplied to the engine by lowering the temperature secondarily by the exothermic liquid 22 injected into the protruding portion 21 is supplied in a state in which the temperature is lowered.

상기 오일의 온도가 저하된 상태에서 엔진으로 공급되므로 엔진의 윤할이 원할하게 되고, 또한 냉각 작용도 되는 것이다.Since the oil is supplied to the engine in a state where the temperature of the oil is lowered, the lubrication of the engine becomes smooth and the cooling action is also performed.

이제까지 설명한 바와 같이 본 발명은 하우징 내측에 설치되어 있는 여과지는 발열부재의 돌기와 여과지 고정부재에 의해 쏠림이 없게 되어 정화효율이 높게되고, 오일의 온도를 저하시키므로 엔진의 냉각작용이 커지는 효과를 가져온다.As described above, the present invention provides a filter paper installed inside the housing, which is free from being drawn by protrusions of the heat generating member and the filter paper fixing member, thereby increasing the purification efficiency and lowering the oil temperature, thereby increasing the cooling effect of the engine.
