Description
본 발명은 자동차용 연료탱크에 연료를 주입시 탄화수소(HC) 가스의 외부 누출을 방지하는 연료주입건 장치에 관한 것이다.The present invention relates to a fuel injection gun device that prevents external leakage of hydrocarbon (HC) gas when fuel is injected into an automotive fuel tank.
자동차의 연료탱크(21)에 연료유(가솔린)를 주입하기 위해서는 주입구파이프(22)를 막고 있는 캡(23)을 제거한 후 주유기의 연료주입건(Gun)을 주입구파이프(22)에 삽입시켜 연료를 주입시키게 된다.In order to inject fuel oil (gasoline) into the fuel tank 21 of the vehicle, the cap 23 blocking the inlet pipe 22 is removed, and the fuel injection gun Gun of the lubricator is inserted into the inlet pipe 22 to supply fuel. Will be injected.
그런데 연료탱크(21)는 지열과 배기열을 받으며 주행중 심한 요동에 의한 마찰열 발생 등으로 탱크내부의 온도가 상승하여 연료증발가스(HC가 주성분)가 발생하게 되며 이 HC 가스는 캐니스터에 흡착 저장하였다가 엔진의 구동시 퍼지콘트롤 밸브를 통해 흡기계에 공급하여 연소시킨 후 배출하므로써 그대로 대기로 방출하게 될 때 발생되는 대기오염을 예방하고 있다.However, the fuel tank 21 receives geothermal heat and exhaust heat, and the temperature inside the tank rises due to frictional heat generation due to severe fluctuations while driving, and thus fuel evaporation gas (HC is the main component) is generated and the HC gas is adsorbed and stored in the canister. When the engine is driven, it is supplied to the intake system through the purge control valve, burned, and then discharged to prevent air pollution generated when released to the atmosphere.
그러나 종래의 경우 연료주입캡(23)을 열고 연료주입건을 통해 연료를 주입하게 되면 연료증발가스는 탱크(21)내의 압력 증가에 의해 개방된 주입구파이프(22)와 연료주입건과의 틈새를 통해 대기로 그대로 방출되어지게 되므로써 환경오염을 유발하고 연료의 손실을 초래하게 되는 문제점이 있었다.However, in the conventional case, when the fuel injection cap 23 is opened and fuel is injected through the fuel injection gun, the fuel evaporation gas passes through a gap between the injection hole 22 and the fuel injection gun opened by the pressure increase in the tank 21. As it is emitted into the atmosphere as it is, there is a problem that causes environmental pollution and fuel loss.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 연료탱크 내에 연료를 주입시 주입구파이프를 통한 탄화수소가스(연료증발가스)의 외부 누출을 방지하여 환경오염을 방지하고 연료 낭비를 막는 연료주입건 장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and its object is to prevent environmental pollution and prevent fuel waste by preventing external leakage of hydrocarbon gas (fuel evaporation gas) through the inlet pipe when fuel is injected into the fuel tank. To provide a fuel injection gun device that prevents.

도 1은 본 발명에 의한 연료주입시 HC 가스의 외부 누출 방지 구조를 갖는 연료주입건을 나타내는 도면이며, 도 2는 연료주입건의 작동상태를 나타내는 도면이며, 도 3은 스페이서의 형상을 나타내는 도면이다.1 is a view showing a fuel injection gun having an external leakage prevention structure of HC gas when fuel injection according to the present invention, Figure 2 is a view showing the operating state of the fuel injection gun, Figure 3 is a view showing the shape of the spacer. .
도면중 부호 1은 권총과 같은 형상으로 연료주입구 파이프(2) 내에 삽입시켜 주유소 저장탱크 내의 연료를 차량에 주입하는 연료주입건이며 손잡이(3)를 손가락으로 당기게 되면 연료가 펌핑되어 그의 선단을 통해 토출하게 된다.In the drawing, reference numeral 1 denotes a pistol-like shape, which is inserted into the fuel inlet pipe 2 to inject fuel from a gas station storage tank into a vehicle, and when the handle 3 is pulled with a finger, the fuel is pumped through its tip. Discharge.
연료의 토출시 이를 안내하도록 주입구파이프(2) 내에 삽입되는 연료안내 파이프(4)의 선단에는 링부재(5)와 +자형리브(6)로 구성된 제1 스페이서(7)가 고정되고 제1 스페이서(7)로부터 일정 간격 이격되도록 제2 스페이서(8)가 고무튜브(9)를 개재하여 고무튜브(9) 선단에 고정되어 있다.A first spacer 7 composed of a ring member 5 and a + -shaped rib 6 is fixed to the tip of the fuel guide pipe 4 inserted into the inlet pipe 2 so as to guide it when the fuel is discharged. The second spacer 8 is fixed to the tip of the rubber tube 9 via the rubber tube 9 so as to be spaced apart from the predetermined distance 7 by the rubber tube 9.
상기 제2 스페이서(8)의 형상 역시 제1 스페이서(7)의 형상과 동일하게 링부재(10)와 +자형 리브(11)로 구성되며 제2 스페이서(8)의 +자형 리브(10)의 중앙부와 상기 손잡이(3)는 케이블(12)로 연결되어 있다.The shape of the second spacer 8 is also composed of the ring member 10 and the + -shaped rib 11 in the same manner as the shape of the first spacer 7 and the + -shaped rib 10 of the second spacer 8. The central part and the handle 3 are connected by a cable 12.
그리고 +자형 리브에 의해 형성되는 연료 토출구멍은 연료펌프로부터 압송되는 연료량보다 작게 토출되도록 하여 고무튜브(9)에 연료압이 가해지도록 하는 것이 바람직하다.The fuel discharge hole formed by the + -shaped rib is preferably discharged smaller than the amount of fuel pumped from the fuel pump so that the fuel pressure is applied to the rubber tube 9.
여기서 미설명 부호 13은 제2 스페이서(8)를 원상 복귀토록 탄발하는 리턴스프링으로 제1 스페이서(7)에 지지된다.In this case, reference numeral 13 is supported by the first spacer 7 as a return spring that causes the second spacer 8 to return to its original position.
이상과 같은 본 발명은 연료주입건(1)을 주입구파이프(2)에 삽입 후 손잡이(3)를 잡아당기면 연료가 안내파이프(4)를 따라 연료탱크로 유입됨과 동시에 케이블(12)이 손잡이(3)에 의해 견인되어 제2 스페이서(8)가 상승하게 된다.In the present invention as described above, when the fuel injection gun 1 is inserted into the inlet pipe 2 and pulls the handle 3, fuel is introduced into the fuel tank along the guide pipe 4 and the cable 12 is handled ( It is towed by 3) and the second spacer 8 is raised.
제2 스페이서(8)가 상승하게 되면 고무튜브(9)는 연료압에 의하여 고무풍선처럼 팽출되어 주입구파이프(2) 내벽에 밀착되므로 연료탱크 내의 연료증발가스가 주입구파이프(2)와 안내파이프(4)와의 틈새를 통하여 외부로 유출되는 것이 차단되고 연료증발가스는 리턴라인(14)(15)을 통하여 캐니스터 및 연료탱크로 귀환되어지게 된다.When the second spacer 8 rises, the rubber tube 9 expands like a rubber balloon by the fuel pressure and comes into close contact with the inner wall of the inlet pipe 2, so that the fuel evaporation gas in the fuel tank is injected into the inlet pipe 2 and the guide pipe ( Outflow to the outside through the gap with 4) is blocked and the fuel evaporation gas is returned to the canister and fuel tank through the return line (14, 15).
이상과 같은 본 발명은 연료주입건의 선단에 고무튜브에 의한 스페이서를 장착하고 스페이서를 손잡이에 케이블로 연결하는 것에 의해서 손잡이를 잡아당기게 되면 스페이서가 상승하여 고무튜브가 팽창할 수 있는 여유를 가지게 되므로써 연료압에 의하여 고무튜브가 팽출하여 주입구파이프 내벽면에 밀착하여 틈새를 밀봉하게 되어 연료증발가스의 외부 누출을 방지하게 되는 효과가 있다.The present invention as described above is equipped with a spacer by a rubber tube at the tip of the fuel injection gun and pulling the handle by connecting the spacer to the handle by the cable, the spacer is raised to have room to expand the rubber tube fuel The rubber tube swells by pressure to close the inlet pipe inner wall to seal the gap, thereby preventing the leakage of fuel evaporation gas.
