본 고안은 내연기관의 펌프에 의해 펌핑되는 연료를 여과시키는 내연기관용 연료여과기에 관한 것으로, 특히, 펌핑되는 연료를 여과기 본체내에서 충돌 분산시키도록 하고, 분산된 연료중 수분 및 물은 여과기 본체 하방내에 집수되도록 하여 차량이 기울거나할 경우 집수된 물이 연료공급관측으로 유입되지 않도록하며, 겨울에 물이 결빙되어 유입관을 막는 것을 방지하고자 하는 것이다.The present invention relates to a fuel filter for an internal combustion engine that filters fuel pumped by a pump of an internal combustion engine, and in particular, to impinge and disperse the pumped fuel in the filter body, and the water and water in the dispersed fuel are below the filter body. If the vehicle is inclined so that the water is collected, the collected water does not flow into the fuel supply pipe, and the water is frozen in winter to prevent the inflow pipe from being blocked.

종래 내연기관용 연료여과기에 있어서는 여과체를 종이필터로 되어 있기 때문에 연료와 함께 유입되는 물이 상기 종이필터에 포집되어 연료의 공급을 막는 결함이 지적되고 있고, 수분 및 물이 여과기본체 내하방의 집수탱크에 집수되더라도 차량이 기울 경우에는 집수된 물이 종이필터를 통해 내연기관측으로 유입되는 사례가 있어 연소가 제대로 이루이지지 않으며, 상기 집수탱크는 여과기본체의 유입관과 곧바로 연통되어 있으므로, 집수탱크내의 수분 및 물등이 유출관측으로 유출되지 않더라도 유입관측으로 되돌아나갈 염려가 있다.In the conventional fuel filter for internal combustion engines, since the filter body is made of a paper filter, a defect is pointed out that water flowing in with the fuel is trapped in the paper filter to prevent the supply of fuel. Even if the tank is collected, if the vehicle is inclined, the collected water flows into the internal combustion engine through the paper filter, and combustion is not performed properly. Even if the moisture and water in the container do not flow out to the outflow side, there is a risk of returning to the inflow side.

따라서, 유입관 내측벽에는 수분등이 잔존되어 있게 마련되므로, 겨울에 있어서는 이 수분등이 결빙되어 연료의 공급을 원할하게 하지 못하는 결함이 지적되고 있다.Therefore, since moisture and the like remain on the inner wall of the inflow pipe, it is pointed out that a defect in which the moisture and the like freezes in the winter, thereby making it difficult to supply fuel.

본 고안은 상기와 같은 결함을 해소하기 위하여 유입관을 여과기본체 내하방에 길게 연설하고, 그 직상방에 반구형상의 밀폐 요홈부를 가지는 필터 조립내통을 필터조립 외통에 끼우되, 필터조립내통 하방의 환턱과 여과기본체 내하방의 격판상방 사이에 수분억제 섬유포를 개재시키고, 집수탱크내의 영구자석 상방에 수분흡수 섬유포를 재치시키도록 하는 것으로, 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above defects, the present invention extends the inlet pipe to the inside and bottom of the filtration main body, and inserts a filter assembly inner cylinder having a hemispherical closed groove in the filter assembly outer cylinder immediately above the filter assembly inner cylinder. Interposed between the upper and lower portions of the inner and lower diaphragm of the filtration main body, and to place the water-absorbing fiber cloth above the permanent magnet in the collecting tank, as described in detail by the accompanying drawings as follows.

즉, 여과기 본체(1) 하방과 상방 각각에 연료 유입관(1') 및 연료유출관(1")을 형성하고, 여과기 본체(1)내하방에 격판(6)을 일체로 돌설하여 격판과 격판사이에 집수탱크부(3)를 형성시킨것에 있어서, 상기 연료유입관(1')을 여과기 본체(1) 내하방 상부로 길게 연설하여 연설관(4)을 형성하고, 필터조립내통(5) 하방에 반구형상의 밀폐요홈부(5')를 형성하여 상기 연설관(4) 직상방에 위치토록하며, 필터조립내통(5) 하방 외주면의 환턱(5")과 여과기 본체(1) 내하방에 일체로 돌출시킨 격판(6) 상방의 사이에 수분억제섬유포(7)를 개재시키고, 집수탱크부(3)에 설치된 공지한 영구자석(8)(8') 상방에 수분흡수섬유포(9)(9')를 재치시켜서된 것으로, 도면중 5'"는 환턱(5")에 뚫은 구멍, 10은 필터조립외통, 11은 다공섬유로된 필터, 5'" 및 10'는 필터조립 내통 및 외통 각각의 구멍, 12는 결합체이며, 연료유입관(1')은 여과기 본체(1)에 일체로 형성되어 있고, 연료유출관(1")은 필터조립외통(10)과 일체로 형성되어 있다. 또한, 필터조립외통(10)의 하방은 필터조립내통의 환턱(5")에 끼워지도록 되어 있으며, 여과기 본체(1)는 투명 합성수지제로 되어 있다.That is, the fuel inlet tube 1 'and the fuel outlet tube 1 "are formed below and above the filter main body 1, and the diaphragm 6 is integrally protruded below and inside the filter main body 1, In the collecting tank portion 3 formed between the diaphragms, the fuel inlet pipe 1 'is extended long and upward in the upper and lower portions of the filter main body 1 to form a speech tube 4, and the filter assembly inner cylinder 5 ) Hemispherical concave groove portion 5 'is formed below to be positioned directly above the speaker tube 4, and the inner jaw 5 " and the filter body 1 inside and outside the filter assembly inner cylinder 5 The water-absorbing fiber cloth 7 is interposed between the diaphragm 6 protruding integrally from the diaphragm 6 above the well-known permanent magnets 8 and 8 'installed in the collecting tank 3. (9 '), 5' "in the figure is a hole drilled in the round jaw (5"), 10 is a filter assembly outer cylinder, 11 is a filter made of porous fibers, 5 '"and 10' is a filter assembly inner cylinder and Outer cylinder Yoke 12 is conjugate, and the fuel inlet pipe (1 ') is formed integrally with the filter body (1), a fuel outflow pipe (1 ") is formed integrally with the filter assembly outer tube (10). In addition, the lower part of the filter assembly outer cylinder 10 is fitted to the annulus 5 "of the filter assembly inner cylinder, and the filter main body 1 is made of transparent synthetic resin.

상기에 있어서, 수분억제섬유포(7)는 화학섬유계열(예 : 나이론등)로 여러겹을 지그재그로 하여 직조시킨 것으로, 수분을 흡수하지 못하며 일시적으로 수분 또는 물의 상승을 억제시키는 역할을 하게 되는 것으로 상승억제 능력치는 섬유의 두께에서 결정된다.In the above, the water-inhibiting fiber cloth (7) is woven in a zigzag of several layers of chemical fiber series (e.g., nylon, etc.), which does not absorb water, and temporarily rises to play a role of suppressing the increase of water or water. Inhibition capacity is determined in the thickness of the fiber.

그리고, 수분흡수섬유포(9)(9')는 천연섬유 계열에서 유지방분을 100% 제거시킨후 다공 조직을 형성하고 여기에 친수성 화학물질을 도포 건조시킨 것으로 흔히 여성생리대, 아기들의 기저귀등에 많이 쓰이고 있는 공지의 것이다.The water-absorbing fiber cloth (9) (9 ') is 100% removed from the natural fiber-based milk fat to form a porous tissue and apply a hydrophilic chemical to it is often used in women's sanitary napkins, diapers of babies That is known.

이상과 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

공지한 바와같이 내연기관의 연료 펌핑작용에 의해 연료 탱크로부터 연료가 여과기 본체(1) 하방의 연료유입관(1')으로 유입되게 되는데, 연료유입관(1')으로 유입되는 연료는 연료유입관(1')의 연설관(4)를 통해 유입듸면서 필터조립내통(5) 하방의 반구형상의 밀폐요홈부(5') 내벽에 충돌되면서 화살표와 같이 집수탱크부(3)측으로 비산 낙하되게 된다.As is known, fuel is introduced from the fuel tank into the fuel inlet pipe 1 'below the filter main body 1 by the fuel pumping action of the internal combustion engine, and the fuel introduced into the fuel inlet pipe 1' is the fuel inlet. As it enters through the speaker tube 4 of the pipe 1 'and collides with the inner wall of the semi-spherical recessed recess 5' below the filter assembly inner cylinder 5, it falls to the collection tank 3 side like an arrow. do.

따라서, 반구형상의 밀폐요홈부(5') 내벽에 충돌되는 연료는 비산 낙하되면서 비중이 무거운 수분 및 물과 분리되게 되는데, 비중이 무거워 낙하되는 수분 및 물은 영구자석(8)(8') 상방의 수분흡수섬유포(9)(9')에 의해 흡수되고, 연료는 낙하되더라도 수분 및 물보다는 비중이 가벼우므로 수분흡수 섬유포(9)(9')에 흡수되지 않고 펌핑작용에 의해 상부로 유출되게 된다.Therefore, the fuel impinging on the inner wall of the hemispherical closed recess 5 'is separated from the heavy water and water with heavy specific gravity while being scattered, but the water and water falling due to the high specific gravity are above the permanent magnet 8, 8'. Is absorbed by the water-absorbing fiber cloth (9) (9 '), and even if the fuel falls, the specific gravity is lighter than the water and water, so that it is not absorbed by the water-absorbing fiber cloth (9) (9') and is pumped out by the pumping action. do.

이때, 수분흡수 섬유포(9)(9')에 포집되어지는 물 또는 수분은 그 포집의 정도가 포화상태에 이르거나 차량의 진동등에 의해 집수탱크부(3)에 낙하되게 되므로 연료에 혼합된 물 또는 수분을 집수탱크부(3)에 집수시킬 수 있게 된다.At this time, the water or water collected in the water-absorbing fiber cloth (9) (9 ') is dropped into the collection tank (3) by the degree of collection reaches the saturation state or the vibration of the vehicle, so that the water mixed with the fuel Alternatively, water can be collected in the collecting tank unit 3.

그리고, 상부로 유출되는 연료는 수분억제섬유포(7)를 통하여 필터조립내통(5)의 환턱(5")에 뚫은구멍(5'")으로 유출되면서 1차 여과 되고, 1차 여과된 연료는 필터조립내통 및 외통 각각의 구멍(5'")과 구멍(10')사이의 다공섬유로된 필터(11)에 의해 2차 여과되면서 유출관(1")을 통해 내연기관측으로 공급되게 된다.And, the fuel flowing out to the upper is first filtered through the water restrained fiber cloth (7) to the hole (5 '") perforated in the annulus (5") of the filter assembly inner cylinder (5), the primary filtered fuel is Secondary filtering is performed by the filter 11 made of a porous fiber between the hole 5 '"and the hole 10' of each of the inner and outer cylinders of the filter assembly, and is supplied to the internal combustion engine through the outlet pipe 1". .

상기에 있어서, 내연기관의 펌핑작용에 의해 집수탱크부(3)내의 수분 및 물이 상부로 유출될 경우에는 수분억제섬유포(7)에 의해 수분 및 물의 유출을 억제하게 되므로, 다공서유로된 필터(11)가 수분 및 물의 포집에 의해 막히는 경우를 배제시켜 여과된 연료를 원할하게 공급할수 있는 것이다.In the above, when the water and water in the collection tank unit 3 is discharged to the upper portion by the pumping action of the internal combustion engine, it is suppressed the outflow of the water and water by the moisture-inhibiting fiber cloth (7), so that the filter Filtered fuel can be supplied smoothly, except that (11) is blocked by the collection of water and water.

즉, 물은 그 표면이 연료(기름)보다 거칠고, 입자가 크며, 무겁기 때문에 펌핑작용에 의해 물이 상승되더라도 수분억제섬유포(7)에 의해 똑바로 올라가지 못하고 지그재그 상승되어 그 상승속도가 연료(기름)보다는 더욱 느리게 되므로 물과 물이 합쳐져 방울이 되고 따라서 그 무게가 무거워지므로 차량의 진동등에 의해 수분흡수섬유포(9)(9')측으로 낙하되게 된다.That is, since the surface of the water is rougher than the fuel (oil), the particles are larger, and heavier, even if the water is raised by the pumping action, the water does not go straight up by the water-inhibiting fiber cloth (7) but zigzags up and the rising speed is increased by the fuel (oil). Since it is slower than the water and the water is combined to form a drop, and thus the weight is heavy, so that the water-absorbing fiber cloth (9) (9 ') by the vibration of the vehicle falls to the side.

따라서, 상술한 바와같이 수분흡수섬유포(9)(9')에 포집되는 수분 또는 물은 그 포집의 정도가 포화상태에 이르러 물등의 자체 중량에 의해 집수탱크부(3)측으로 자연 낙하되거나 차량의 진동에 의해 집수탱크부(3)측으로 낙하되어 집수되게 되는 것이다.Therefore, as described above, the water or water collected in the water-absorbing fiber cloth 9 (9 ') is naturally dropped to the collection tank unit 3 by its own weight such as water or the like when the degree of collection reaches saturation. It will fall to the collection tank part 3 side by vibration and will be collected.

그러나, 연료(기름)는 물보다는 훨씬 가벼우므로 수분억제포(7)를 따라 용이하게 상승되게 된다.However, since the fuel (oil) is much lighter than water, the fuel (oil) is easily lifted along the moisture suppression cloth (7).

그리고, 본 고안은 상술한 바와같이 연료유입관(1)을 여과기 본체(1) 내하방의 상방으로 길게 연설시켜 연설관(4)를 형성시켰으므로, 차량이 기울거나할 경우 집수탱크부(3)내의 수분 및 물이 이 연설관(4)에 의해 유입관(1)측으로 되돌아 나갈 염려가 없다.In addition, since the present invention forms the speech pipe 4 by extending the fuel inlet pipe 1 upward and downward inside the filter main body 1 as described above, when the vehicle is inclined, the collection tank part 3 There is no fear that the moisture and water in the inside may return to the inflow pipe 1 side by the speech pipe 4.

따라서, 차량 정지시 유입관(1)내에 수분 및 물이 잔존되어 있지 않게 되므로 겨울에 이들의 결빙에 의해 연료의 공급이 막히는 사례를 방지할수 있게 되는 것이다.Therefore, since water and water do not remain in the inlet pipe 1 when the vehicle is stopped, it is possible to prevent the case where fuel supply is blocked by their freezing in winter.

이상과 같이 본 고안은 공급되는 연료를 연설관을 통해 밀폐 요홈부에 충돌케하여 와류 비산케하고, 연료내의 수분 및 물을 분리시켜 수분 및 물을 집수탱크부에 집수토록함과 동시에, 연료만을 1차, 2차로 여과시켜 순수한 연료를 내연기관에 공급토록하며, 차량이 운행시 기울거나할 경우에도 집수탱크부내의 물이 유입관측으로 되돌아 나가지 않도록 하므로써 겨울에 차량정지시 온도 하강에 의해 물이 빙결되지 않도록 하여 연료의 공급을 원할하게 할수 있는 실용적인 고안이다.As described above, the present invention makes the supplied fuel impinge on the concave groove through the speaker tube, causing the vortex to scatter, separating the water and the water in the fuel to collect the water and the water into the collecting tank, and at the same time, only the fuel The first and second filtration are used to supply pure fuel to the internal combustion engine, and the water in the collection tank does not return to the inflow view even when the vehicle is tilted during operation. It is a practical design that can smoothly supply fuel by preventing freezing.
