본 발명은 차량의 연료탱크에 관한 것으로, 특히 연료탱크에 주유건으로 연료를 주입할 때에 연료의 흔들리는 유면이나 거품 등으로 인해 연료의 주입이 조기에 차단되는 것을 방지할 수 있도록 된 연료주입시 조기 공급중단방지장치에 관한 것이다.The present invention relates to a fuel tank of a vehicle. In particular, when the fuel is injected into the fuel tank as fuel, the fuel supply is prevented from being blocked early due to the fluctuating oil level or bubbles of the fuel. An interruption prevention device.

일반적으로 차량의 연료장치는 일정량의 연료를 저장할 수 있는 연료탱크와, 이 연료탱크내의 연료를 펌핑하여 공급하는 연료펌프, 이 연료펌프에서 펌핑된 연료를 엔진에 공급하는 연료분사장치 및, 연료증기가 대기중으로 방출하는 것을 방지하기 위해 연료증발가스를 포집하는 캐니스터 등을 갖추고 있다.In general, a fuel device of a vehicle includes a fuel tank capable of storing a certain amount of fuel, a fuel pump for supplying a fuel in the fuel tank, a fuel injection device for supplying the fuel pumped from the fuel pump to an engine, and fuel vapor In order to prevent the gas from being released into the atmosphere, a canister for collecting fuel evaporation gas is provided.

여기서 상기 연료탱크는 도1에 도시된 바와 같이 박스형상을 하고서 차체의 후방에 장착되어 지지되고, 상기 연료탱크(10)에는 외부에서 연료를 주입할 수 있도록 필라 넥(11)이 비스듬히 설치되며, 상기 필라 넥(11)을 개폐하기 위한 캡(도시되지 않음)이 구비되는 한편, 연료주입시에 연료탱크내의 증발가스를 환기시킴과 더불어 연료의 과주입을 방지하는 레벨링 파이프(12)가 연료탱크와 필라 넥(11)에 각각 연결된 상태로 설치되어 있다.Here, the fuel tank is mounted and supported at the rear of the vehicle body in a box shape as shown in FIG. 1, and the pillar tank 11 is installed at an angle so that the fuel tank 10 can be injected with fuel from the outside. A cap (not shown) for opening and closing the pillar neck 11 is provided, while a leveling pipe 12 which ventilates the boil-off gas in the fuel tank during fuel injection and prevents over-injection of fuel is provided in the fuel tank. And pillar necks (11) are respectively installed in a connected state.

상기와 같은 구조의 연료탱크에 도1에 도시된 바와 같이, 주유건(13)을 상기 필라 넥(11)에 삽입하여 연료를 주입하게 되는 데, 이러한 연료의 주입과정에 연료를 공칭용량의 유면(L) 만큼 주입할려면 여러 번 주유건을 사용해야하는 불편함이 있었다.As shown in FIG. 1, the fuel tank having the above structure is inserted into the pillar neck 11 to inject fuel. In order to inject as much as (L) it was inconvenient to use a gas gun several times.

즉, 도2에 도시된 바와 같이, 연료를 주입하는 과정에 연료가 연료탱크내에 수평한 유면을 유지하면서 차 오르는 것이 아니라 주유건을 통해 분사되는 주입에너지 때문에 연료유면이 불규칙하게 되고, 이러한 불규칙한 연료유면은 상기 레벨링 파이프의 입구를 막게 되어, 연료탱크내의 압력이 상기 필라 넥(11)을 통해 주유건(13)에 작용하고, 이 압력 때문에 주유건의 볼밸브가 자동 스톱홀을 막아주게 되므로, 주유건을 통한 연료의 주입이 자동적으로 중단되게 되는 현상이 발생하고 있었다.That is, as shown in FIG. 2, the fuel surface becomes irregular due to the injected energy injected through the main fuel, rather than the fuel rising while maintaining the horizontal oil level in the fuel tank during the fuel injection process. The oil level blocks the inlet of the leveling pipe so that the pressure in the fuel tank acts on the gas gun 13 through the pillar neck 11, and this pressure causes the ball valve of the oil gun to block the automatic stop hole. Injection of fuel through the gun was automatically stopped.

상기와 같이 연료를 공칭용량 만큼 주유하는 과정에 연료가 공칭용량 만큼 주입되기 이전에 연료주입이 자동적으로 중단되면, 주유자는 연료유면이 잠잠해질 때까지 기다렸다가 다시 주유건으로 연료를 주입해야하고, 이러한 동작을 여러 번 반복해야하는 불편함이 발생되고 있었다.If the fuel injection is automatically stopped before the fuel is injected at the nominal capacity in the process of refueling the fuel at the nominal capacity as described above, the lubricator must wait until the fuel level is silent and inject the fuel again into the gas gun. Discomfort was having to be repeated several times.

특히 디젤연료의 경우에는 연료주입시에 연료탱크내에 거품까지 형성되고, 이러한 거품으로 인해 연료의 조기 주입중단현상이 자주 발생하는 문제점이 있었다.Particularly, in the case of diesel fuel, bubbles are formed in the fuel tank at the time of fuel injection, and there is a problem in that premature injection stoppage occurs frequently due to such bubbles.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 연료의 주입시에 불규칙한 유면이나 거품으로 인해 연료가 공칭용량 만큼 주입되기 이전에 레벨링 파이프가 연료나 연료거품으로 인해 막혀서 연료주입이 중단되는 현상을 방지하여 연료주입시의 편의성을 부여할 수 있도록 된 연료주입시의 조기 공급중단방지장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and the fuel injection is stopped due to the leveling pipe being blocked by the fuel or the fuel foam before the fuel is injected as much as the nominal capacity due to irregular oil or bubble during fuel injection. The purpose of the present invention is to provide an early supply stop prevention device during fuel injection, which can provide convenience for fuel injection.

상기와 같은 목적을 달성하기 위한 본 발명은, 연료탱크내의 증발가스를 환기시키기 위해 연료탱크와 필라 넥에 각각 연결되도록 설치된 레벨링 파이프로 연료주입시 흔들리는 유면이나 거품이 진입하지 못하도록 방지하는 진입방지수단을 갖추고 있다.In order to achieve the above object, the present invention provides a leveling pipe installed to be connected to the fuel tank and the pillar neck to ventilate the boil-off gas in the fuel tank. Equipped with.

바람직하기로는, 상기 진입방지수단이 상기 레벨링 파이프의 입구를 감싸도록 끼워져서 다수개의 고정대를 매개로 레벨링 파이프에 장착됨과 더불어 상기 고정대를 중심으로 상하로 다수개의 통기홀이 형성된 조기 공급중단방지파이프를 갖춘 것을 특징으로 한다.Preferably, the entry preventing means is inserted so as to surround the inlet of the leveling pipe is mounted on the leveling pipe via a plurality of fixing rods, and the pre-supply stoppage prevention pipe having a plurality of ventilation holes formed up and down about the fixing rods.

이하, 본 발명의 실시예를 첨부된 도면을 참조하면서 상세히 설명한다.Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

도3은 본 발명에 따른 연료주입시 조기 공급중단방지파이프가 연료탱크에 설치된 상태도이고, 도4는 본 발명에 따른 조기 공급중단방지파이프의 상세도인 바, 즉 연료탱크(10)에 외부에서 연료를 주입할 수 있도록 필라 넥(11)이 설치되고, 연료주입시에 상기 연료탱크(10)내의 증발가스를 환기시킴과 더불어 연료의 과주입을 방지하는 레벨링파이프(12)가 연료탱크와 필라 넥(11)에 각각 연결된 상태로 설치되며, 상기 레벨링 파이프(12)의 주입구에는 조기 공급중단방지파이프(14)가 연료탱크의 내측방향으로 연장되게 설치되어 있다.FIG. 3 is a state diagram in which an early supply stoppage prevention pipe is installed in a fuel tank according to the present invention, and FIG. 4 is a detailed view of an early supply stoppage prevention pipe according to the present invention, that is, from the outside of the fuel tank 10. A pillar neck 11 is installed to inject fuel, and a leveling pipe 12 for venting boil-off gas in the fuel tank 10 and preventing over-injection of fuel during fuel injection is provided with a fuel tank and a pillar. It is installed in the state connected to the neck 11, respectively, the inlet of the leveling pipe 12, the premature supply stop prevention pipe 14 is installed to extend in the inner direction of the fuel tank.

여기서, 상기 조기 공급중단방지파이프(14)는 도4에 자세히 도시된 바와 같이, 상기 레벨링 파이프(12)의 입구를 감싸도록 레벨링 파이프(12)에 끼워져서 적절한 고정수단으로서 예컨대 고정대(15)를 매개로 고정되어 있는 데, 이 고정대(15)는 레벨링 파이프(12)와 조기 공급중단방지파이프(14)사이에 90°의 각도를 두고 배열되어 조기 공급중단방지파이프(14)를 레베링 파이프(12)에 장착하도록 되어 있지만, 여기에 한정되지 않고 조기 공급중단방지파이프(14)를 레벨링 파이프(12)에 적절히 고정시킬 수 있다면 2개 혹은 그 이상의 개수를 사용할 수 있음은 물론이다.Here, the pre-supply interruption prevention pipe 14 is fitted to the leveling pipe 12 so as to surround the inlet of the leveling pipe 12, as shown in detail in FIG. The fastener 15 is arranged at an angle of 90 ° between the leveling pipe 12 and the early stoppage prevention pipe 14 so that the early stoppage prevention pipe 14 is provided with a levering pipe ( 12, but the present invention is not limited thereto, and two or more can be used as long as the pre-supply stop prevention pipe 14 can be properly fixed to the leveling pipe 12.

또한, 상기 조기 공급중단방지파이프(14)는 상기 고정대(15)를 중심으로 상하로 통기홀(16)이 형성되어, 연료탱크내의 증발가스가 상기 통기홀을 통해 레벨링 파이프를 거쳐서 외부로 통기되게 되어 있다.In addition, the premature supply stop prevention pipe 14 is formed with a vent hole 16 up and down about the holder 15, so that the boil-off gas in the fuel tank is vented to the outside through the leveling pipe through the vent hole. It is.

상기와 같이 조기 공급중단방지파이프(14)를 설치한 상태로 연료주입건(13)을 통해 연료탱크에 연료를 주입하는 과정에 도5에 도시된 바와 같이, 연료의 유면이 흔들려서 불규칙하게 되거나 연료거품이 형성되어도, 이러한 불규칙한 유면이나 연료거품 등은 상기 조기 공급중단방지파이프(14)에 의해 레벨링 파이프로의 진입이 차단되게 되므로, 연료가 공칭용량의 유면(L)까지 공급되기 이전에 불규칙한 유면이나 연료거품 등으로 인해 레벨링 파이프가 막혀서 연료의 조기 유입이 차단될 염려가 없게 되는 것이다.As shown in FIG. 5, in the process of injecting fuel into the fuel tank through the fuel injection gun 13 while the pre-supply stoppage prevention pipe 14 is installed as described above, the oil level of the fuel is irregular or the fuel is shaken. Even if bubbles are formed, such irregular oil level or fuel bubbles are blocked from entering the leveling pipe by the early supply stop prevention pipe 14, so that the irregular oil level before the fuel is supplied to the oil level L of the nominal capacity. The leveling pipe is blocked by fuel bubbles or the like, and there is no fear that the early inflow of fuel is blocked.

즉, 연료탱크내에 연료가 주입되면서 연료탱크내의 유면이 심하게 흔들릴 경우에도 상기 조기 공급중단방지파이프(14)내로 유입된 연료의 유면은 대체로 수평을 유지하게 되므로, 연료의 조기 공급중단현상이 발생되지 않게 되는 것이다.That is, even when fuel is injected into the fuel tank and the oil level in the fuel tank is severely shaken, the oil level of the fuel introduced into the premature supply stop prevention pipe 14 is generally leveled, thus preventing the early supply stoppage of the fuel. It will not be.

그리고, 연료탱크내의 증발가스로 인한 압력은 상기 통기홀을 통해 레벨링 파이프를 거쳐서 외부로 환기되므로, 원활한 주유가 이루어질 수 있게 된다.In addition, since the pressure caused by the boil-off gas in the fuel tank is vented to the outside through the leveling pipe through the vent hole, smooth oiling can be achieved.

이상 설명한 바와 같이, 본 발명에 따른 연료주입시 조기 공급중단방지장치에 의하면, 연료를 공칭용량까지 주입하는 과정에 발생하는 흔들리는 유면이나 연료거품 등이 조기 공급중단방지파이프에 의해 레벨링 파이프로 진입하지 못하게 되므로, 연료를 공칭용량까지 주입하기 이전에 흔들리는 유면이나 연료거품 등으로 인해 레벨링 파이프가 막혀서 연료의 공급이 중단될 염려가 없게 되어, 신속하고 원활한 주유가 가능한 효과가 있다.As described above, according to the premature supply stop prevention device in the fuel injection according to the present invention, the shaking oil surface or fuel bubbles generated in the process of injecting the fuel up to the nominal capacity does not enter the leveling pipe by the early supply stop prevention pipe. Since the leveling pipe is clogged by the oil level or the fuel bubble which is shaken before the fuel is injected to the nominal capacity, the supply of the fuel is not interrupted, and thus the fuel can be quickly and smoothly supplied.
