본 발명은 자동차 연료탱크의 흡,배기장치에 관한 것으로, 보다 구체적으로는 자동차의 주행중 탱크에 담겨진 연료의 유동에 의해 생성되는 가스를 탱크밖으로 배출시켜줌과 아울러 연료가 엔진쪽으로 원활하게 공급될 수 있도록 탱크밖의 공기를 유입시켜 주는 자동차 연료탱크의 흡,배기장치이다.The present invention relates to an intake / exhaust device of an automobile fuel tank, and more specifically, to discharge the gas generated by the flow of fuel contained in the tank while driving the vehicle to the outside of the tank and to smoothly supply the fuel to the engine. It is the intake / exhaust system of automobile fuel tank that injects the air outside the tank.

일반적으로 자동차의 연료탱크에 담겨진 연료는 자동차의 주행중 유동되고, 이로 인하여 연료탱크 내부는 가스로 충만되어 있기 마련인데 이때 연료탱크 내부의 압력이 대기압 이하로 떨어지기 때문에 엔진의 연료분사 기구쪽으로 연료공급 상태가 불량하게 되므로 연료탱크 내부의 압력을 대기압 수준으로 유지시켜 주는 것이 바람직하다.In general, the fuel contained in the fuel tank of the vehicle is flowed while the vehicle is running, and thus the fuel tank is filled with gas. Since the condition is bad, it is desirable to maintain the pressure inside the fuel tank at atmospheric pressure.

그러나 종래에는 가스 배출기구와 대기 유입기구가 하나의 파이프로 되어 있어 가스 배출시 연료와 함께 배출되고 대기 흡입시 이물질 및 습기가 동시에 흡입될 뿐 아니라 장착작업이 매우 번거로운 등의 문제점이 있었다.However, in the related art, the gas discharge device and the air inlet device are formed in one pipe, and thus, the gas discharge device and the air inlet device are discharged together with the fuel when the gas is discharged, and foreign substances and moisture are sucked at the same time when the air is sucked.

그리고 이미 알려진 국내실용공개 89-10534호는 스프링기구로서 유체를 제어하는 것이나 대기와 같이 연약한 압력에서는 사용할 수 없다.In addition, Korean Utility Model Publication No. 89-10534, which is known as a spring mechanism, is used for controlling fluids and at low pressures such as air.

본 발명은 가스배출시 연료배출 방지기능과 대기유입시 이물질유입 방지기능을 하고, 장착 작업이 매우 용이한 자동차 연료탱크의 흡,배기장치로서 본 발명의 실시예를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is described in detail with reference to the accompanying drawings an embodiment of the present invention as an intake and exhaust device of a vehicle fuel tank that prevents fuel emissions during gas discharge and foreign matters inflow during air inflow, and is very easy to install. Same as

본 발명은 제1도에 예시한 바와같이 자동차 연료탱크(FT)의 상부에 장착되는 것으로서, 제2도에 예시된 바와같이 하우징(1) 내부에 흡,배기 밸브어셈블리(2)를 내장하여서 된 것이다.The present invention is mounted on the upper portion of the vehicle fuel tank (FT), as illustrated in FIG. 1, by incorporating the intake and exhaust valve assembly (2) in the housing (1) as illustrated in FIG. will be.

하우징(1) 한쪽 끝에는 연료탱크(FT) 밖으로 길게 연장된 호오스(H)와 연결되는 도관(3)이 배관되어 있고, 하우징(1)의 다른 끝에는 연료탱크(FT)와 연통된 호오스(4)와 연결되는 도관(5)이 밸브시트(6)가 형성된 나팔관체(7) 모양으로 일체로 성형되어, 억지끼워 맞춤되어 있따. 도관(3)에는 원통형 밸브시트(8)가 형성되어 있다. 이곳에 흡,배기 밸브어셈블리(2)가 안내되게 설치되어 있다. 이 밸브어셈블리(2)는 벽체(14)에 구멍(15)이 뚫려있고 이 구멍들을 개폐시키는 박막형 밸브체(12)가 중앙에 꽂혀 설치되어 있다.At one end of the housing 1 a conduit 3 is connected to the hose H which extends out of the fuel tank FT, and at the other end of the housing 1 a hose 4 communicating with the fuel tank FT. The conduit 5, which is connected to the conduit, is integrally molded into the shape of the fallopian tube body 7 in which the valve seat 6 is formed, and fits tightly. The conduit 3 is formed with a cylindrical valve seat 8. Here, the intake and exhaust valve assembly 2 is guided. The valve assembly 2 is provided with a hole 15 formed in the wall 14 and a thin film valve body 12 for opening and closing the holes is inserted into the center.

그리고 밸브어셈블리(2) 아래에 중공부(11')를 갖는 밸브체(11)가 꽂혀 그 얇은 플랜지(13)가 나팔관체(7)의 밸브시트(6)을 개폐시키게 얹혀 설치되어 있다.And the valve body 11 which has the hollow part 11 'is inserted under the valve assembly 2, and the thin flange 13 is installed so that the valve seat 6 of the fallopian tube 7 may be opened and closed.

도면중 미설명부호(9)는 구멍, (10)은 하우징의 부착편, (16)은 틈새이다.In the figure, reference numeral 9 denotes a hole, 10 denotes an attachment piece of the housing, and 16 denotes a gap.

이와같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

본 발명을 제1도와 제2도에 예시된 바와같이 연료탱크(FT) 내부에서 생성된 가스를 화살표(a)로 표시한 방향으로 배출시켜 주고 대기는 화살표(b)로 표시한 방향으로 연료탱크(FT) 내부로 유입시켜 준다.As illustrated in FIG. 1 and FIG. 2, the gas is discharged in the direction indicated by arrow a and the atmosphere is discharged in the direction indicated by arrow b. (FT) flows into the inside.

즉, 연료탱크(FT) 내부에서 생성된 가스를 화살표(a)로 표시한 바와같이 연료탱크(FT)에 담겨진 연료를 소모할때, 즉 연료의 액면강하현상이 일어나면서 연료탱크(FT) 내부의 압력이 떨어질때 연료탱크(FT)밖의 대기는 도관(3), 원통형 밸브시트(8)와, 흡,배기 어셈블리(2)의 벽체(14)쪽 구멍(15)를 지나면서 박막형밸브(12)를 쇄선으로 표시한 바와같이 밀면서 중공형밸브(11)의 중공부(11')를 통과하고, 나팔관체(7)를 지나 도관(5)과 호오스(4)를 통해 연료탱크(FT) 내부로 유입된다. 그리고 연료탱크(FT) 내부에서 생성된 가스는 화살표(a)로 표시한 바와같이 연료탱크(FT)에 담겨진 연료를 소모할때, 즉 연료의 액면강하현상이 일어나면서 연료탱크(FT) 내부의 압력이 떨어질때 호오스(4)가 도관(5)을 지나 나팔관체(7)의 밸브시트(6)와 접하고 있던 중공형밸브(11)의 얇은 플랜지(13)을 밀면서 흡,배기 밸브어셈블리(2)의 벽체(14)와 원통형 밸브시트(8) 사이의 틈새(16)를 지나 원통형 밸브시트(8)와 도관(3) 그리고 호오스(H)를 통해 대기중으로 방출된다.That is, when the gas generated inside the fuel tank FT is consumed by the fuel contained in the fuel tank FT, as indicated by the arrow a, that is, the liquid level drop of the fuel occurs, and the inside of the fuel tank FT. The pressure outside the fuel tank FT passes through the conduit 3, the cylindrical valve seat 8, and the hole 15 toward the wall 14 of the intake and exhaust assembly 2 when the pressure of the fuel tank FT drops. ), As shown by the dashed line, passes through the hollow portion 11 'of the hollow valve 11, passes through the fallopian tube 7, and inside the fuel tank FT through the conduit 5 and the hose 4 Flows into. The gas generated inside the fuel tank FT consumes the fuel contained in the fuel tank FT, as indicated by the arrow (a), that is, the liquid level drop of the fuel occurs. When the pressure drops, the hose 4 passes through the conduit 5 and pushes the thin flange 13 of the hollow valve 11 that is in contact with the valve seat 6 of the fallopian tube 7 while the intake / exhaust valve assembly 2 It passes through the gap 16 between the wall 14 and the cylindrical valve seat 8 of the valve and discharges into the atmosphere through the cylindrical valve seat 8, the conduit 3 and the hose (H).

이와같은 본 발명은 연료탱크(FT) 내부에서 생성된 가스의 배출기능과 연료의 원활한 공급에 필요한 대기의 유입기능을 겸하는 것으로서 종래의 스프링식 또는 다이아프램식 밸브장치에 비하여 구조가 매우 간단하고 고장의 우려가 없어 작동의 신뢰도가 매우 높으며, 저렴한 비용으로 만들 수 있을 뿐 아니라 장착이 매우 용이한 장점이 있다.The present invention combines the function of discharging the gas generated inside the fuel tank (FT) and the inflow of the air required for the smooth supply of fuel, and the structure is very simple and troublesome as compared to the conventional spring or diaphragm valve device. There is no concern about the high reliability of the operation, it can be made at a low cost as well as very easy to install.
