본 고안은 연료 유출방지장치에 관한 것으로서, 보다 상세하게는 연료가 주입되는 퓨얼필러 튜브(Fuel Pillar Tube)에 신축성(伸縮性)이 강한 판막을 설치함으로써 외부물체와 강하게 충돌되더라도 연료가 외부로 유출되지 않도록 한 것이다.The present invention relates to a fuel outflow prevention device, and more specifically, by installing a highly flexible valve on a fuel filler tube into which fuel is injected, fuel leaks to the outside even if it strongly collides with an external object. It is not to be.
종래에는 제1도의 연료 유출방지장치의 작동상태를 보인 단면도에서 보는 바와 같이, 자동차에 연료를 주입하기 위한 장치는 퓨얼필러 튜브(10)의 끝단에 퓨얼 캡(Fuel Cap.12)이 체결되어 있고 이 퓨얼필러 튜브(10) 내측에는 벤트 호올(Vent Hole.14) 및 연료주입공(16)이 관통된 차단막(18)이 설치되어 있으며 이 차단막(18)의 일면에는 핀(20)에 의해 리플렉터(Reflector,22)가 밀착되어 있다.Conventionally, as shown in the cross-sectional view showing the operating state of the fuel leakage prevention apparatus of FIG. 1, the fuel cap (12) is a fuel cap (Fuel Cap. 12) is fastened to the end of the fuel filler tube (10) Inside the fuel filler tube 10, a barrier film 18 through which a vent hole 14 and a fuel injection hole 16 are penetrated is installed, and one surface of the barrier film 18 is reflected by a fin 20. (Reflector, 22) is in close contact.
자동차에 연료를 주입하고자 할 경우에는, 퓨얼 캡(12)을 열고 연료 주입건(도시 안됐음)을 차단막(18)의 연료 주입공(16)에 삽입하여 연료를 주입하면 차단막(18)의 일면에 설치된 리플렉터(22)가 밀림과 동시에 연료가 주입된다. 완전히 연료가 주입되어 연료 주입건을 연료주입공(16)에서 빼면 스프링의 특성을 지닌 리플렉터(22)가 다시 차단막(18)의 일면에 밀착됨으로써 연료가 외부로 유출되지 않게 된다.When the fuel is to be injected into the vehicle, the fuel cap 12 is opened, and a fuel injection gun (not shown) is inserted into the fuel injection hole 16 of the blocking film 18 to inject fuel, and one surface of the blocking film 18 is injected. Fuel is injected at the same time as the reflector 22 installed at the side is pushed. When the fuel is completely injected and the fuel injection gun is removed from the fuel injection hole 16, the reflector 22 having the characteristic of a spring comes into close contact with one surface of the blocking film 18 so that fuel does not flow out.
그러나 상기의 장치는 구조가 복잡하므로 제작상에 있어 제작비용이 과다함은 물론 리플렉터(22)의 반복작용으로 파손되는 경우가 많다. 즉, 연료주입건으로 주입할 때마다 리플렉터(22)가 핀(20)을 중심으로 차단막(18)의 연료주입공(16)을 개방 및 차단을 자주하게 되면 점차적으로 리플렉터(22)의 스프링상수(Spring Rate)가 저하됨에 따라 밀착하는 힘이 상실되어 차단막(18)의 연료주입공(16)을 통하여 연료가 외부로 유출되는 사례가 있었고, 또한 다른 물체와의 접촉은 물론 특히, 충돌시에는 리플렉터(22)가 파손되어 연료가 쉽게 외부로 유출되는 문제점이 발생되었다.However, since the apparatus is complicated in structure, the manufacturing cost is excessive in manufacturing, and it is often broken by the repeated action of the reflector 22. That is, whenever the reflector 22 frequently opens and shuts off the fuel injection hole 16 of the blocking film 18 around the fin 20 every time it is injected into the fuel injection gun, the spring constant of the reflector 22 gradually increases ( As the spring rate decreases, the adhesion force is lost and fuel is leaked to the outside through the fuel injection hole 16 of the blocking film 18. In addition, the reflector is not only in contact with other objects, but also in a collision. There was a problem in that the 22 was broken and the fuel easily flowed out.
본 고안은 상기와 같은 문제점을 고려하여 창안한 것으로서, 본 고안의 목적은 퓨얼필러 튜브에 신축성(伸縮性)이 강한 판막을 클램프(Clamp)로 연결 설치함으로써 제작상의 간편함은 물론 외부물체와 강한 충돌을 하더라도 연료가 외부로 유출되지 않도록 하는데 있다.The present invention was conceived in consideration of the above problems, and the object of the present invention is to install a highly elastic valve on the fuel filler tube with a clamp, thereby simplifying manufacturing and a strong collision with an external object. Even if the fuel does not leak to the outside.
상기와 같은 목적을 달성하기 위한 본 고안의 특징은, 연료가 주입되는 퓨얼필러 튜브에 있어서, 연료가 유출되지 않도록 상기 퓨얼필러 튜브에 복수개의 벤트호올이 관통된 신축성이 강한 판막 및 러버 튜브(Rubber Tube)가 클램크에 의해 체결되어 있는 것에 있다.A feature of the present invention for achieving the above object is, in the fuel filler tube is injected fuel, a highly flexible valve and rubber tube through which a plurality of vent holes penetrate the fuel filler tube so that fuel is not leaked (Rubber Tube) is fastened by a clamp.
이하, 본 고안을 첨부된 도면에 의거하여 설명하면 다음과 같다. 도면중, 제2도는 본 고안인 연료 유출방지 장치를 분리하여 나타낸 사시도이고, 제3도는 본 고안인 연료 유출방지장치를 조립하여 나타낸 단면도이다.Hereinafter, the present invention will be described with reference to the accompanying drawings. 2 is a perspective view showing the fuel leakage preventing device of the present invention separately, and FIG. 3 is a sectional view showing the fuel leakage preventing device of the present invention assembled.
일단에 퓨얼 캡(50)이 체결된 퓨얼필러 튜브(52)의 타단에 복수개의 벤트호올(54)이 관통되고 신축성이 강한 재질인 폴리프로필렌 판막(56)을 설치하고 이 폴리프로필렌 판막(56)의 외부에 러버 튜브(58)를 클램프(60)로 감싼 후, 볼트(62)와 너트(64)를 조여 설치한다.On the other end of the fuel filler tube 52 to which the fuel cap 50 is fastened at one end, a plurality of vent hoses 54 pass through and a polypropylene valve 56 made of a highly elastic material is installed, and the polypropylene valve 56 is provided. The rubber tube 58 is wrapped around the outside with the clamp 60, and then the bolt 62 and the nut 64 are tightened and installed.
이와 같이 구성된 상태에서, 자동차에 연료를 주입할 경우에는 퓨얼 캡(50)을 열고 연료 주입건(도시 안됐음)을 퓨얼필러 튜브(52)에 주입하면 폴리프로필렌 판막(56)의 끝부분이 오므라들게 되어 연료가 유출되지않게 된다. 또 연료주입을 자주 반복하더라도 상기 폴리프로필렌 판막(56)의 신축성이 상실되지 않게 되어 연료의 유출을 방지하게 된다.In such a configuration, when fuel is injected into the vehicle, the fuel cap 50 is opened and a fuel injection gun (not shown) is injected into the fuel filler tube 52 so that the end portion of the polypropylene valve 56 is lifted. To prevent fuel from spilling. In addition, even if the fuel injection is repeated frequently, the elasticity of the polypropylene plate 56 is not lost, and the outflow of fuel is prevented.
만약, 외부물체와 강한 충돌을 하게 되더라도 폴리프로필렌 판막(56)이 부드럽고 신축성이 강하기 때문에 파손되지 않아 연료가 외부로 유출됨을 방지하게 된다.If a strong collision with an external object is made, the polypropylene valve 56 is soft and elastic, so that it is not damaged and thus prevents fuel from flowing out.
이상에서와 같이 본 고안인 연료 유출방지장치에 따르면, 퓨얼필러 튜브(52)에 신축성이 강한 판막(56)을 클램프(60)로 연결 설치함으로써 제작상의 간편함은 물론 외부물체와 강한 충돌을 하더라도 연료가 외부로 유출되지 않게 되는 효과가 있다.According to the fuel outflow prevention device of the present invention as described above, by installing the highly flexible valve 56 to the fuel filler tube 52 by the clamp 60, the fuel is easy to manufacture as well as a strong collision with external objects. There is an effect that does not leak to the outside.
