Abstract
Description
본 발명은 디젤엔진 연료계의 연료 필터의 기밀성 향상을 위한 연료 필터 가스켓의 구조 개선에 관한 것이다.The present invention relates to the improvement of the structure of the fuel filter gasket for improving the airtightness of the fuel filter of the diesel engine fuel system.
연료계는 모든 운전 조건하에서 엔진에 필요한 혼합기를 가장 연소하기 쉬운상태로 공급하는 장치로서 엔진의 성능, 특히 엔진 출력이나 경제성을 크게 좌우하는 중요한 장치이다.The fuel gauge is a device that supplies the mixer necessary for the engine under the most operating conditions in the most easily burnable state, and is an important device that greatly influences the performance of the engine, in particular, the engine power and economy.
이 연료계의 주요부는 연료를 공기와 적절히 혼합시켜 엔진에 공급하는 기화기나 또는 연료분사장치, 연료를 저장하는 연료탱크, 연료속에 있는 수분과 먼지등을 제거하는 연료 필터, 연료를 압송하는 연료펌프등으로 구성되며, 이들 구성들은 연료파이프로 연결되어 있다.The main part of the fuel system is a carburetor or fuel injection device that properly mixes fuel with air and supplies it to an engine, a fuel tank for storing fuel, a fuel filter for removing moisture and dust in the fuel, and a fuel pump for pumping fuel. Etc., and these components are connected by fuel pipes.
연료속에 포함된 수분이나 먼지등의 이물질이 연소실에 유입되면 연소 효율을 저하시키고 피스톤 운동부의 마모를 촉진하게 되므로 상기에서 열거한 것과 같이 연료 필터가 연료계에 필히 장착되고 있는데, 도 3에 도시하는 것과 같이 연료 필터(4)는 하우징(5)내에 엘리먼트(6)가 수용되고, 엘리먼트(6)의 단부를 통해 연료가 누설되지 않도록 가스켓(7)을 개재하여 헤드덮개(8)를 하우징(5)에 계합하고 있다.When foreign substances such as moisture or dust contained in the fuel flow into the combustion chamber, the combustion efficiency is reduced and the wear of the piston moving part is promoted. Therefore, the fuel filter is necessarily installed in the fuel system as described above. As described above, the fuel filter 4 includes the head cover 8 through the gasket 7 so that the element 6 is accommodated in the housing 5 and fuel is not leaked through the end of the element 6. We are engaged in).
그런데 종래의 경우 연료 필터 가스켓(7)은 도 4의 상세도에 도시하는 것과 같이 단면한 모습이 직사각형인 몸체(9) 안쪽에 날개부(10)가 돌출된 원형구조물로 형성되어, 하우징(5)에 엘리먼트(6)를 삽입하고 연료 필터 가스켓(7)을 엘리먼트(6) 상단면에 위치시킨 후 헤드덮개(8)를 일정조임 토오크를 부여하여 하우징(5)에 체결할때 직사각형 몸체(9)가 적절히 눌러지게 되면서 밀봉력을 가지도록 구성되어 있으나 이는 구조적으로 다음과 같은 문제점을 가지는 것으로 밝혀지고 있다.By the way, in the conventional case, the fuel filter gasket 7 is formed of a circular structure in which the wing portion 10 protrudes inside the body 9 having a rectangular cross section as shown in the detailed view of FIG. Insert the element (6) into the fuel filter gasket (7) on the top surface of the element (6) and then apply a tightening torque to the head cover (8) to tighten the housing (5). ) Is configured to have a sealing force is properly pressed, but it has been found to have the following problems in structure.
이러한 종래 구조의 연료 필터 가스켓(7)은 상온내지 영하 20℃ 범위내에서사용하는데 있어서는 기밀성 유지에 크게 지장을 초래하지는 않으나 혹한기, 예를 들면 영하 30℃ 이하에서의 저온 시동시나 운전시 가스켓의 밑면이 평면이어서 변형이 일어날때 누유 될 수 있는 공간의 형성으로 인해 연료의 누설을 일으켜 엔진의 출력 저하나 엔진 부조 및 난조 현상이 발생하는 것으로 보고 되고 있는바, 이는 극저온에서 물성치가 변형된 후 복원이 안되기 때문으로서 복원력의 부족은 연료 필터 가스켓(7)의 직사각형 몸체(9)의 구조적 취약성에 기인한 것으로 본 발명인에 의해 확인되었다.The fuel filter gasket 7 having such a conventional structure does not significantly interfere with maintaining airtightness when used within a range of room temperature to minus 20 ° C., but the underside of the gasket during cold start or operation at a low temperature such as minus 30 ° C. or less This plane has been reported to cause fuel leakage due to the formation of a space that can leak when deformation occurs, resulting in a decrease in engine output or engine relief and hunting. As a result, the lack of restoring force has been confirmed by the inventors as being due to the structural weakness of the rectangular body 9 of the fuel filter gasket 7.
이에 본 발명은 상기한 점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 복원력 유지에 의한 시일성이 우수하여 혹한기의 연료유 누설을 방지할 수 있는 구조의 연료 필터의 기밀성 향상을 위한 연료 필터 가스켓을 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above, and its object is to provide a fuel filter gasket for improving the airtightness of a fuel filter having a structure capable of preventing leakage of fuel oil in cold weather due to excellent sealing property by maintaining restoring force. It is.
상기한 목적을 달성하기 위하여 본 발명은 연료 필터의 하우징에 수용되어 연료의 외부 누설을 방지하는 연료 필터 가스켓에 있어서, 단면한 모습이 타원형이며 링형상인 몸체와;In order to achieve the above object, the present invention is a fuel filter gasket accommodated in the housing of the fuel filter to prevent the external leakage of fuel, the cross-sectional shape is oval and ring-shaped body;
그 몸체의 안쪽으로 연장 돌출된 날개부;를 포함하여 구성되는 것을 특징으로 한다.Characterized in that it comprises a; wing portion protruding inwardly of the body.

이하 본 발명의 구성을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 의한 연료 필터 가스켓의 정단면도이고, 도 2는 본 발명에 의한 연료 필터 가스켓의 평면도이다.1 is a front sectional view of a fuel filter gasket according to the present invention, and FIG. 2 is a plan view of a fuel filter gasket according to the present invention.
연료 필터 가스켓(1)은 평면에서 본 전체 형상이 원형, 즉 링 형상이고, 몸체(2)와 날개부(3)로 구성되어 있다.The fuel filter gasket 1 has a circular planar shape, that is, a ring shape, and is composed of a body 2 and a wing 3.
몸체(2)는 단면하여서 보았을 때 속이 빈 중공형의 타원형상이며, 날개부(3)는 타원형 몸체(2)의 내측으로 일체로 연장 돌출되어 있다.The body 2 is a hollow hollow oval shape when viewed in cross section, and the wing portion 3 protrudes integrally into the inner side of the elliptical body 2.
이와같은 본 발명은 하우징(5)내에 엘리먼트(6)를 삽입하고 엘리먼트(6) 상단에 연료 필터 가스켓(1)을 올려 놓고 헤드덮개(8)로 적절한 압력이 연료 필터가스켓(1)에 작용하도록 체결하면, 타원형 몸체(2)가 약간 찌그러지면서 팽창력 작용에 의해 시일하여 연료유의 누설을 방지하게 된다.The present invention inserts the element 6 into the housing 5 and places the fuel filter gasket 1 on top of the element 6 so that the appropriate pressure with the head cover 8 acts on the fuel filter gasket 1. When fastened, the elliptical body 2 is slightly distorted and sealed by the expansion force to prevent leakage of fuel oil.
본 발명의 경우 가스켓(1)의 접촉면이 직사각형에 의한 평면이 아니라 타원형에 의한 측면이기 때문에 접촉력이 분산되지 아니하고 원주상으로 집중되어, 즉, 선접촉에 의해 밀봉력이 향상되므로써 극저온에서의 물성치가 변하여 뒤틀림이 일어나더라도 원상 복귀가 가능하고 접촉점이 안정적으로 유지되어지게 되는 것이다.In the case of the present invention, since the contact surface of the gasket 1 is an oval side rather than a plane by a rectangle, the contact force is not dispersed but concentrated circumferentially, that is, the physical properties at cryogenic temperatures are improved by improving the sealing force by line contact. Even if the change and distortion occurs, it is possible to return to the original position and the contact point is maintained stably.
이상과 같은 본 발명은 연료 필터의 누설 방지를 위해 사용되는 연료 필터 가스켓이 종래와 달리 직사각형이 아닌 타원형 몸체를 가지도록 형성하는 것에 의해 극저온에서 물성치가 변해서 뒤틀려지더라도 접촉점이 안정적으로 유지되고 복원력이 우수하여 극저온하에서의 엔진 시동시 및 주행시 연료유의 누설 현상을 방지할 수 있는 효과가 있다.The present invention as described above is formed so that the fuel filter gasket used to prevent the leakage of the fuel filter has an elliptical body rather than a rectangular shape unlike the conventional one, even if the physical properties change and warp at cryogenic temperatures, the contact point remains stable and the restoring force is improved. It is excellent in that it is possible to prevent the leakage of fuel oil when starting the engine and driving at cryogenic temperatures.
