본 발명은 각종 내연기관에 사용되는 오일필터의 구조를 개량하여 엔진오일에 포함되어 있는 각종 불순물의 필터링 효과를 더욱더 향상시켜줌과 동시에, 점도율을 장기간 유지시켜 엔진오일의 교환시기를 대폭 연장시켜주고, 특히 필터내에 압력이 발생되어 오일이 순환되지 않을때는 소정의 가동체가 구동되도록 하여 엔진에 오일을 계속 공급시켜 줄 수 있도록 한 내연기관용 오일필터에 관한 것이다.The present invention improves the filtering effect of various impurities contained in the engine oil by improving the structure of the oil filter used for various internal combustion engines, and at the same time maintains the viscosity rate for a long time, greatly extending the engine oil replacement time. In particular, the present invention relates to an oil filter for an internal combustion engine that allows a predetermined movable body to be driven when pressure is generated in the filter so that the oil is not circulated so that the oil can be continuously supplied to the engine.

종래의 내연기관에 설치되는 오일필터(도시생략됨)는 상부가 개구된 원통몸체의 중앙부에 다수개의 오일유입공이 저부에 천공된 배출관이 설치되고, 상기 원통몸체의 내벽과 배출관의 외주면 사이에는 여과필터가 설치되며, 상기 원통몸체의 개구부에는 다수개의 오일유입공과 오일배출공이 천공된 뚜껑체를 씌워 고정시킨 구성으로 되어 있었다.The oil filter (not shown) installed in a conventional internal combustion engine is provided with a discharge pipe having a plurality of oil inlet holes perforated at the center of a cylindrical body having an open top, and filtered between an inner wall of the cylindrical body and an outer peripheral surface of the discharge pipe. A filter is installed, and the opening of the cylindrical body has a configuration in which a plurality of oil inlet holes and oil discharge holes are covered with a capped body.

따라서, 각종 불순물이 포함되어 있는 오일은 뚜껑체의 오일유입공을 통해 원통몸체를 갖는 필터내부로 유입되어 여과필터를 거쳐 필터링된 다음, 배출관의 저부 오일유입공을 통해 배출관내로 유입되어, 상기 오일배출공을 거쳐 내연기관에 유입된다.Therefore, the oil containing various impurities are introduced into the filter having a cylindrical body through the oil inlet hole of the lid body and filtered through the filtration filter, and then flows into the discharge tube through the bottom oil inlet hole of the discharge pipe. It enters the internal combustion engine via the oil discharge hole.

그러나, 이와같은 구성은 비교적 조밀하지 못한 하나의 여과필터를 사용하여 오일내의 불순물을 여과시켜줌에 따라 여과 효율이 낮을 뿐만 아니라, 장기간 사용하였을 경우, 여과필터내에 걸려있던 이물질이 다시 빠져나와 내연기관에 유입되어 피스톤과 실린더를 마모시키게 될 우려가 있으며, 장기간 사용하여 여과필터가 막혔거나, 필터내에 소정의 압력이 발생되어 오일의 흐름이 차단 되었는데도 불구하고, 사용자가 이를 인식하지 못하고 내연기관을 계속 구동시킬 경우, 피스톤이 실린더의 내벽에 달라붙게 됨은 물론이거니와 뚜껑체의 오일유입공 내벽에 별도의 역류방지 장치가 구비되어 있지않아 필터의 내부압력이 오일의 유입압력보다 클 경우, 오일이 유입공을 통해 역류하게 되는등의 문제점이 있었다.However, such a structure is not only low in filtration efficiency by filtering impurities in the oil by using a relatively inexpensive filtration filter, but also when used for a long time, foreign substances trapped in the filtration filter come out again to the internal combustion engine. There is a risk of inflow and abrasion of the piston and cylinder, and even though the filtration filter is clogged for a long time or a certain pressure is generated in the filter, the flow of oil is blocked. In this case, the piston will not stick to the inner wall of the cylinder, and there is no separate backflow prevention device on the inner wall of the oil inlet hole. There was a problem such as backflow through.

본 발명은 이와같은 종래의 문제점을 해소시켜주기 위해 안출한 것으로, 다수개의 오일유입공이 천공된 뚜껑체의 저부에 역류방지용 고무판을 설치하고, 원통몸체의 중앙부에 설치되는 제1배출관의 상, 하부에는 다수개의 오일유입공을 형성시키되, 상기 제1배출관의 상부에는 내부의 압력에 의해 선택적으로 구동되는 제2배출관을 설치하며, 상기 제1배출관의 외주면에 끼워지는 여과필터는 투과율이 서로다른 다수개의 여과필터를 설치하여 주므로서, 필터링효과가 향상되어 엔진오일의 교환시기를 대폭 연장시켜줄 수 있음은 물론, 여과필터가 막히거나 필터내에 공기등이 유입되어 필터내의 내압이 오일의 유입력보다 크게되어 오일의 흐름이 차단되면, 제2배출관의 가동체가 구동되어 오일이 내연기관에 직접 공급됨에 따라 피스톤이 실린더의 내벽에 달라붙은 것을 방지할 수 있을 뿐만 아니라, 내압에 의한 오일의 역류를 미연에 방지할 수 있게되어, 제품의 신뢰도를 더욱더 향상시킬 수 있는 내연기관용 오일필터를 제공하는 것을 목적으로하며, 이하 첨부된 도면을 참조하면 본 발명을 상세히 설명하면 다음과 같다.The present invention has been made in order to solve such a conventional problem, the upper and lower portions of the first discharge pipe is installed in the central portion of the cylindrical body by installing a backflow prevention rubber plate on the bottom of the lid body is a plurality of oil inlet holes perforated There are formed a plurality of oil inlet hole, the upper portion of the first discharge pipe is installed a second discharge pipe selectively driven by the internal pressure, the filtration filter fitted to the outer peripheral surface of the first discharge pipe has a plurality of different permeability By installing two filtration filters, the filtering effect is improved, which greatly extends the engine oil replacement period, as well as the filtration filter is clogged or air is introduced into the filter. When the flow of oil is blocked, the movable body of the second discharge pipe is driven so that the oil is supplied directly to the internal combustion engine, so that the piston It is an object of the present invention to provide an oil filter for an internal combustion engine that not only prevents sticking to the wall but also prevents reverse flow of oil due to internal pressure, thereby further improving the reliability of the product. Referring to the drawings, the present invention will be described in detail as follows.

제1도 및 제2도에 나타낸 바와같이, 본 발명의 구성은 통상의 원통몸체(1) 중앙부에 설치된 제1배출관(2)의 상하부에는 다수개의 오일유입공(3), (4)이 천공되고, 그의 외주면에는 투과율이 서로 다른 다수개의 여과필터(5), (6), (7)가 설치된다.As shown in FIG. 1 and FIG. 2, the structure of the present invention comprises a plurality of oil inlets (3), (4) perforated in the upper and lower portions of the first discharge pipe (2) provided in the center of the ordinary cylindrical body (1). On the outer circumferential surface thereof, a plurality of filtration filters 5, 6, and 7 having different transmittances are provided.

또한, 상기 제1배출관(2)의 상부에는 다수개의 오일유입공(8)이 상부에 천공된 깔대기형 제2배출관(9)이 재치되며, 상기 제2배출관(9)의 외주면에 끼워져, 통상시 상기 오일유입공(8)에 위치되는 가동체(10)는 그의 저부에 탄설된 코일스프링(11)에 탄지되고, 다수개의 오일유입공(12)이 천공되어, 상기 원통몸체(1)의 상면에 고정된 뚜껑체(13)의 저면에는 역류방지용 고무판(14)이 설치된다.In addition, a funnel-shaped second discharge pipe 9 having a plurality of oil inlet holes 8 drilled thereon is mounted on an upper portion of the first discharge pipe 2, and is fitted to an outer circumferential surface of the second discharge pipe 9, and The movable body 10 positioned at the oil inlet hole 8 is supported by the coil spring 11 installed at the bottom thereof, and a plurality of oil inlet holes 12 are punched out of the cylindrical body 1. On the bottom of the lid body 13 fixed to the upper surface, a backflow preventing rubber plate 14 is installed.

여기서, 미설명부호 15는 오일배출구이고, 16은 일단이 개구되어 코일스프링 (11)의 저면을 받쳐주는 ○링이며, 17은 ○링(16)이 끼워지는 걸림홈이고, 18은 여과필터(7)를 받쳐주는 걸림턱이며, 19는 제1배출관(2)의 유동을 방지하는 유동방지턱이다.Here, reference numeral 15 denotes an oil discharge port, 16 is an o-ring which is open at one end to support the bottom of the coil spring 11, 17 is a locking groove into which the o-ring 16 is fitted, and 18 is a filtration filter ( 7) is a stopping jaw supporting the 19, 19 is a flow preventing jaw to prevent the flow of the first discharge pipe (2).

이와같이 구성된 본 발명 오일필터의 작용효과를 제2도를 참조하여 설명하면 다음과 같다.Referring to Figure 2 the effect of the oil filter of the present invention configured as described above is as follows.

먼저, 내연기관을 순환하고, 도시생략된 송유관을 통해 오일필터로 되돌아온 오일은 뚜껑체(13)에 천공된 다수개의 오일유입공(12)을 통해 필터내를 유입되는데, 이 때 역류방지용 고무판(14)은 필터의 내부압력이 오일의 유입압력보다 클 경우, 상기 오일유입공(12)을 막게되므로, 필터내부의 오일이 역류되는 것을 방지할 수 있고, 작을 경우, 제2도의 일점쇄선과 같이 아래방향으로 밀리게 되어 오일이 필터내로 유입될 수 있게 된다.First, the internal combustion engine is circulated, and the oil returned to the oil filter through the oil pipe illustrated in the drawing is introduced into the filter through a plurality of oil inflow holes 12 perforated in the lid body 13. 14) blocks the oil inlet hole 12 when the internal pressure of the filter is greater than the inlet pressure of the oil, so that oil in the filter can be prevented from flowing back, and when small, as shown in the dashed-dotted line of FIG. It is pushed downward so that oil can flow into the filter.

각종 불순물을 포함하고, 이와같이 필터내를 유입된 오일은 비교적 투과율이 높은 여과필터(5)를 통해 1차 필터링된 후, 펄프등으로 구성되어 상기 여과필터(5)보다 비교적 투과율이 낮은 여과필터(6)를 통해 2차 필터링된 다음, 상기 여과필터(5)와 그 구조가 같은 여과필터(7)를 거쳐 3차 필터링된 연후 하부유입공(3)을 통해 제1배출관 (2)내로 유입되므로, 종래에 비해 필터링효과가 매우 향상된다. 이 때, 도시생략된 내연기관에서는 흡입력을 계속 발생시키고 있으므로, 제1배출관(2)내로 유입된 오일은 뚜껑체(13)의 배출구(15)를 통해 배출되어 내연기관내로 유입된다.The oil, which contains various impurities and is introduced into the filter in this way, is first filtered through a filtration filter 5 having a relatively high permeability, and then is composed of pulp or the like and has a filtration filter having a lower permeability than the filtration filter 5 ( After the second filtering through 6), the filter filter 5 and the structure is introduced through the lower inlet hole (3) after the third filtered through the same filter filter (7), so that it is introduced into the first discharge pipe (2). Compared with the conventional method, the filtering effect is greatly improved. At this time, since the suction power is continuously generated in the internal combustion engine, not shown, oil introduced into the first discharge pipe 2 is discharged through the discharge port 15 of the lid 13 and flows into the internal combustion engine.

이 후, 상기와 같은 동작을 장기간 계속해서 반복수행하여 여과필터(5~7)가 불순물에 의해 막히거나, 필터내에 공기가 유입되어 필터내의 내부압력이 코일스프링 (11)의 탄성력보다 크게 발생되었다고 가정하면, 뚜껑체(13)의 오일유입공(12)을 통해 유입된 오일이 제1배출관(2)의 상부 오일유입공(4)을 통해 제2배출관(9)의 상부에 끼워진 가동체(10)의 상면을 압압하게 되므로, 코일스프링(11)의 탄발력을 받는 가동체(10)가 제2도의 일점쇄선과 같이 제2배출관(9)의 외주면을 따라 하측으로 이동된다.Thereafter, the above operation was repeatedly performed for a long time, and the filtration filters 5 to 7 were blocked by impurities, or air was introduced into the filter, so that the internal pressure in the filter was greater than the elastic force of the coil spring 11. Assuming that the oil introduced through the oil inlet hole 12 of the lid body 13 is inserted into the upper portion of the second discharge pipe 9 through the upper oil inlet hole 4 of the first discharge pipe 2 ( Since the upper surface of 10) is pressed, the movable body 10 subjected to the elastic force of the coil spring 11 is moved downward along the outer circumferential surface of the second discharge pipe 9 as shown by the dashed line in FIG.

따라서, 통상시 가동체(10)에 의해 막혀있던 제2배출관(9)의 오일유입공(8)이 개구되므로, 필터내로 유입된 오일은 제1배출관(2)의 오일유입공(4)→제2배출관(9)의 오일유입공(8)을 거쳐 뚜껑체(13)의 배출구(15)를 통해 내연기관에 직접 공급되므로, 오일의 공급이 차단되어 피스톤이 실린더의 내벽에 달라붙게 되는 불상사를 사전에 방지시킬 수가 있는 것이다.Therefore, since the oil inlet hole 8 of the second discharge pipe 9 which is normally blocked by the movable body 10 is opened, the oil introduced into the filter is transferred to the oil inlet hole 4 of the first discharge pipe 2 →. Since the oil supply hole 8 of the second discharge pipe (9) is directly supplied to the internal combustion engine through the outlet (15) of the lid body 13, the oil supply is interrupted and the piston is stuck to the inner wall of the cylinder Can be prevented in advance.

이 후, 사용자가 필터의 내압이 상승하게 된 원인을 제거(즉, 여과필터에 불순물이 가득찬 경우에는 필터 전체를 교환해주고, 내부에 공기등이 유입된 경우에는 공기를 빼줌)해주게 되면, 오일유입공(12)을 통해 유입되는 오일의 유입력이 코일스프링(11)의 탄발력보다 적어지게 되므로, 제2로의 일점쇄선과 같은 상태에 있던 가동체(10)가 원상태로 복원되어 제2배출관(9)의 오일유입공(8)이 가동체(10)에 의해 다시 막히게 되므로, 필터내로 유입된 오일은 전술에서와 같이 각각의 여과필터(5~7)를 통해 필터링된 후, 정상적으로 내연기관내에 공급되므로, 오일의 점도율이 장기간 유지되어, 오일의 교환시기를 대폭 연장시킬 수가 있는 것이다.After that, if the user removes the cause of the increase in the internal pressure of the filter (that is, replaces the whole filter when the filtration filter is full of impurities, and removes the air when the air is introduced into the inside), the oil Since the inflow force of the oil flowing through the inflow hole 12 is less than the resilience force of the coil spring 11, the movable body 10 in the same state as the one-dot chain line to the second is restored to its original state and the second discharge pipe Since the oil inflow hole 8 of 9 is blocked again by the movable body 10, the oil flowing into the filter is filtered through the respective filter filters 5-7 as described above, and then the internal combustion engine is normally operated. Since it is supplied in the inside, the viscosity ratio of oil is maintained for a long time, and the oil replacement time can be extended significantly.

이상에서 설명한 바와같이, 본 발명에 의하면 투과율이 서로다른 3중 여과필터를 설치하여 오일에 포함되어 있는 각종 불순물을 필터링시켜줌에 따라 필터링 효과가 종래보다 더욱더 향상되어 오일의 점도율을 장기간 유지시켜줄 수 있으므로, 엔진오일의 교환시기를 대폭 연장시켜줄 수 있게 되어, 사용자가 경제적인 부담을 덜어줄 수 있을뿐만 아니라, 필터내에 공기가 유입되어 내압이 상승되거나, 여과필터의 막힘현상에 의한 오일의 공급차단으로 발생될 수 있는 피스톤과 실린더의 융착현상을 사전에 방지시킬 수 있고, 또한 필터내의 압력상승에 의한 오일의 역류현상을 미연에 방지시킬 수가 있게되어, 제품의 신뢰도를 더욱더 향상시킬 수가 있는 것이다.As described above, according to the present invention, by installing a triple filtration filter having different permeabilities to filter various impurities contained in the oil, the filtering effect is further improved than before, thereby maintaining the viscosity ratio of the oil for a long time. Therefore, it is possible to greatly extend the replacement period of the engine oil, and not only to reduce the economic burden on the user, but also to cut off the supply of oil due to air flow into the filter to increase the internal pressure or blockage of the filtration filter. It is possible to prevent the fusion phenomenon of the piston and the cylinder which can be generated in advance, and also to prevent the backflow of the oil due to the pressure rise in the filter in advance, further improving the reliability of the product.
