본 고안은 차량의 연료탱크에 관한 것으로, 특히 자동차용 연료탱크의 연료주입장치에 관한 것이다.The present invention relates to a fuel tank of a vehicle, and more particularly to a fuel injection device of a fuel tank for automobiles.
일반적으로 자동차에는 일정량의 연료를 외부에서 주입시켜 저장할 수 있는 연료탱크가 장착되어 있는 바, 이 연료탱크에는 연료를 용이하게 주입할 수 있도록 연료주입구가 형성된 필라가 연료탱크의 상부에 설치됨과 더불어 이 필라의 연료주입구에는 개폐밸브가 힌지를 매개로 회동가능하게 장착되어 있다.In general, a vehicle is equipped with a fuel tank that can be injected and stored a certain amount of fuel from the outside, and the fuel tank is provided with a pillar formed with a fuel inlet to easily inject the fuel in the upper portion of the fuel tank At the fuel inlet of the pillar, an on-off valve is rotatably mounted via a hinge.
그런데 종래의 연료주입장치는 연료주입건을 연료주입구에 밀어넣어 연료를 주입할 때 개폐밸브가 열리면서 가스가 연료탱크로 유입되는 결점이 있었다.However, the conventional fuel injection device has a drawback that gas is introduced into the fuel tank while the on-off valve opens when the fuel injection gun is pushed into the fuel injection port to inject fuel.
이에 본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 연료주입건을 연료주입구로 넣으면 연료주입구멍을 개폐시키는 플리퍼가 열림과 더불어 이 플리퍼와 연동되도록 설치된 비틀림스프링에 의해 개폐밸브가 열려 가스가 캐니스터쪽으로 유입되어 엔진에 공급되도록 구성됨과 더불어, 주유가 끝나고 연료주입건을 빼면 연료탱크쪽만 열리며 캐니스터쪽은 연료탱크내의 정부압시 스프링에 의해 열리고 닫히면 2방향밸브의 기능을 하도록 구성되어, 연료주입건을 연료주입구에 밀어넣으면 개폐밸브가 열리면서 가스가 캐니스터로 유입되어 엔진으로 흐르도록 된 자동차용 연료탱크의 연료주입장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above drawbacks, and when the fuel injection gun is inserted into the fuel inlet, a flipper for opening and closing the fuel injection hole is opened, and an on / off valve is opened by a torsion spring installed to interlock with the flipper. Is configured to flow into the canister and supply to the engine, and when the fuel is finished and the fuel injection gun is removed, only the fuel tank is opened. It is an object of the present invention to provide a fuel injection device for a fuel tank for an automobile in which a fuel injection gun is pushed into the fuel injection port so that an open / close valve opens and gas flows into the canister and flows to the engine.

상기한 바의 목적을 달성하기 위한 본 고안은, 연료캡을 열고 연료주입건을 필라에 형성된 연료주입구로 넣으면 연료주입구를 개폐시키는 플리퍼가 비틀림스프링을 매개로 설치되고, 이 비틀림스프링의 회동에 의해 연료주입챔버에 설치된 캐니스터측출구와 연료탱크측출구가 선택적으로 열리도록 개폐밸브가 설치된 구조로 되어 있다.The present invention for achieving the above object is, when the fuel cap is opened and the fuel injection gun is inserted into the fuel injection hole formed in the pillar, a flipper for opening and closing the fuel injection hole is installed through the torsion spring, and by the rotation of the torsion spring The canister side outlet and the fuel tank side outlet which are installed in the fuel injection chamber can be selectively opened.
이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 연료주입장치를 나타내는 설명도로서, 본 고안의 연료공급장치는, 연료캡(A)을 열고 연료주입건(10)을 필라(20)에 형성된 연료주입구(21)로 넣으면 연료주입구(21)를 개폐시키는 플리퍼(30)가 비틀림스프링(40)을 매개로 설치되고, 이 비틀림스프링(40)의 회동에 의해 연료주입챔버(50)에 설치된 캐니스터측출구(51)와 연료탱크측출구(52)가 선택적으로 열리도록 개폐밸브(60)가 설치된 구조로 되어 있다.1 is an explanatory view showing a fuel injection device according to the present invention, the fuel supply device of the present invention, the fuel injection gun 10 to the fuel injection port 21 formed in the pillar 20 with the fuel cap A opened. The flipper 30, which opens and closes the fuel inlet 21 when installed, is installed through the torsion spring 40, and the canister side outlet 51 provided in the fuel injection chamber 50 by the rotation of the torsion spring 40 and The opening and closing valve 60 is provided so that the fuel tank side outlet 52 can be selectively opened.
여기서 상기 개폐밸브(60)는, 상기 연료주입챔버(50)의 내에서 이동하면서 캐니스터측출구(51)와 연료탱크측출구(52)를 선택적으로 개폐할 수 있도록 된 로드(61)와, 이 로드(61)를 탱크내에 정·부압시 탄발력으로 밀어부치도록 된 스프링(62)과, 상기 로드(61)이 소정위치에 설치되어 기밀을 유지하도록 된 패킹(63)으로 이루어져 있다.Here, the on-off valve 60 is a rod 61 which can selectively open and close the canister side outlet 51 and the fuel tank side outlet 52 while moving in the fuel injection chamber 50, and It consists of a spring 62 which pushes the rod 61 in the tank at the time of positive and negative pressure, and the packing 63 which is installed in a predetermined position and keeps airtightness.
