Description
본 고안은 연료 주입구를 통해 증발 가스가 방출되는 것을 차단하기 위한 증발 가스 차단 장치에 관한 것으로서, 특히 연료 주입구의 하단부에 설치되어 연료의 자중에 의해 열리도록 구성됨으로써 연료 필러 캡을 개방하더라도 증발 가스의 누출이 방지할 수 있는 연료 주입구 셧 오프 밸브에 관한 것이다.The present invention relates to an evaporation gas blocking device for blocking the discharge of the evaporated gas through the fuel inlet, in particular installed in the lower end of the fuel inlet is configured to be opened by the weight of the fuel to open the fuel filler cap even if the A fuel inlet shut off valve is provided to prevent leakage.
종래의 증발 가스 차단 장치는 도 1에 도시된 바와 같이 상단부가 단차지게 형성된 연료 주입구(11)와, 지지봉(13)에 힌지 고정되어 회동되고 상기 연료 주입구(11)의 단차 위치에 설치되는 플래퍼(12)와, 상기 플래퍼(12)의 하측에 설치되어 플래퍼(12)를 탄발시킴으로써 단차 상부를 차단하는 리턴 스프링(14)과, 중앙에 오일 홀(15')이 형성되고 단차 하부에 설치되어 상기 리턴 스프링(14)을 지지하는 스프링 리테이너(15)로 구성되어 있다.As shown in FIG. 1, a conventional evaporation gas blocking device includes a fuel inlet 11 having an upper end stepped with a flapper that is hingedly fixed to a support rod 13 and installed at a stepped position of the fuel inlet 11. 12), a return spring 14 installed at the lower side of the flapper 12 to block the upper step by firing the flapper 12, and an oil hole 15 'is formed at the center and installed at the lower part of the step. The spring retainer 15 which supports the return spring 14 is comprised.
상기와 같이 구성된 종래의 증발 가스 차단 장치는 연료 주입시 오일 건의 가압력에 의해 상기 지지봉(13)이 하강하면서 플래퍼(13)를 열게 됨으로써 연료가 연료 주입구(11)를 통해 연료 탱크(미 도시)로 공급되도록 되어 있다.The conventional boil-off gas blocking device configured as described above opens the flapper 13 while the support rod 13 is lowered by the pressing force of the oil gun during fuel injection, so that fuel passes through the fuel inlet 11 to the fuel tank (not shown). It is intended to be supplied.
연료 주입을 위해 오일 건을 연료 주입구(11)로 밀어 넣으면 오일 건의 선단이 상기 지지봉(13)을 밀게 되고, 지지봉(13)이 밀려 하강되면 상기 플래퍼(12)도 리턴 스프링(14)을 압축시키면서 하강되어 단차부를 열게 된다. 단차부가 열리면 오일 건의 선단을 통해 연료가 빠져 나와 연료 주입구(11)를 통해 연료 탱크(미 도시)로 공급된다.When the oil gun is pushed into the fuel inlet 11 for fuel injection, the tip of the oil gun pushes the support rod 13, and when the support rod 13 is pushed down, the flapper 12 also compresses the return spring 14. It is lowered to open the stepped portion. When the stepped portion is opened, the fuel exits through the tip of the oil gun and is supplied to the fuel tank (not shown) through the fuel inlet 11.
연료 주입이 완료되고 오일 건을 빼내면 상기 리턴 스프링(14)에 의해 플래퍼(12)가 탄발되어 상승하게 되고, 상기 지지봉(13) 역시 상승됨으로써 플래퍼(12)에 의해 단차부가 차단된다. 따라서, 연료 탱크(미 도시)의 증발 가스가 외부로 누출되지 않게 된다.When the fuel injection is completed and the oil gun is pulled out, the flapper 12 is elastically raised by the return spring 14, and the support rod 13 is also raised to block the stepped portion by the flapper 12. Thus, the evaporated gas of the fuel tank (not shown) does not leak to the outside.
그러나, 상기와 같이 구성된 종래의 증발 가스 차단 장치는 연료 주입시 오일 건에 의해 지지봉(13)과 플래퍼(12)가 하강되므로 연료 주입 이전에 단차부가 열려 연료 탱크의 고압 증발 가스가 외부로 배출되는 문제점이 있다.However, since the support rod 13 and the flapper 12 are lowered by the oil gun during fuel injection, the conventional evaporation gas blocking device configured as described above has a stepped portion before the fuel injection to discharge the high pressure evaporated gas of the fuel tank to the outside. There is a problem.
본 고안은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 연료 주입구의 하단에 설치되어 연료의 자중에 의해서만 열리도록 구성됨으로써 증발 가스의 누설이 방지되고 충돌시에도 연료가 누출되지 않도록 하는 연료 주입구 셧 오프 밸브를 제공하는데 그 목적이 있다.The present invention is devised to solve the above problems of the prior art, it is installed at the lower end of the fuel inlet is configured to open only by the weight of the fuel to prevent the leakage of the evaporated gas and to prevent the fuel from leaking in the event of a collision The purpose is to provide an inlet shut off valve.

본 고안은 연료 주입구의 내측 하단으로부터 일정 정도 돌출되도록 설치되고 측면에 연료 주입 홀이 형성된 밸브 바디와, 상기 밸브 바디의 끝단을 막아주는 차단막과, 상기 밸브 바디에 힌지 고정되고 상기 연료 주입 홀을 개폐시키는 차단 밸브와, 일단은 상기 차단막에 결착되고 다른 일단은 밸브 바디에 결착되어 차단 밸브를 탄발시키는 리턴 스프링으로 구성된 것을 특징으로 한다.The present invention is installed so as to protrude from the inner lower end of the fuel inlet to some extent, the valve body is formed with a fuel injection hole on the side, a blocking film to block the end of the valve body, the hinge fixed to the valve body and opening and closing the fuel injection hole It is characterized in that it is composed of a return valve for coupling the shut-off valve, and one end is bound to the blocking film and the other end is bound to the valve body to release the shutoff valve.
이하, 본 고안의 실시 예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 의한 연료 주입구 셧 오프 밸브는 도 2 내지 도 4에 도시된 바와 같이 연료 주입구(60)의 내측 하단으로부터 일정 정도 돌출되도록 설치되고 측면에 연료 주입 홀이 형성된 밸브 바디(51)와, 상기 밸브 바디(51)의 끝단을 막아주는 차단막(52)과, 상기 밸브 바디(51)의 외측에 힌지(53') 고정되고 상기 연료 주입 홀을 개폐시키는 차단 밸브(53)와, 일단은 상기 차단막(52)에 결착되고 다른 일단은 밸브 바디(51)에 결착되어 차단 밸브(53)를 탄발시키는 리턴 스프링(54)으로 구성된다.The fuel inlet shut-off valve according to the present invention is installed so as to protrude to a certain degree from the inner lower end of the fuel inlet 60, as shown in Figure 2 to 4 and the fuel injection hole formed on the side, and the A blocking membrane 52 for blocking the end of the valve body 51, a hinge 53 'fixed to the outside of the valve body 51, a blocking valve 53 for opening and closing the fuel injection hole, and one end of the blocking membrane The other end is composed of a return spring 54 which is fastened to the valve 52 and the other end is fastened to the valve body 51 to force the shutoff valve 53.
상기와 같이 구성된 본 고안의 연료 주입구 셧 오프 밸브는 연료 주입구(60)의 하단부에 설치되어 연료 주입시에만 차단 밸브(53)를 열어 줌으로써 연료가 주입되도록 하게 된다.The fuel inlet shutoff valve of the present invention configured as described above is installed at the lower end of the fuel inlet 60 so that fuel is injected by opening the shutoff valve 53 only at the time of fuel injection.
연료 필러 캡을 열고 연료를 주입하면 연료가 연료 주입구(60)를 통해 하강되고, 연료 주입구(60)의 끝단 부분에서 상기 셧 오프 밸브(50)에 채워지게 된다. 셧 오프 밸브(50)에 채워진 연료는 상기 차단막(52)으로 인해 배출되지 않게 되고, 그 자중이 상기 리턴 스프링(54)의 탄성력을 이길 정도가 되면 상기 차단 밸브(53)가 개방된다.Opening the fuel filler cap and injecting fuel causes the fuel to descend through the fuel inlet 60 and fills the shut off valve 50 at the end of the fuel inlet 60. The fuel filled in the shut-off valve 50 is not discharged by the blocking film 52, and the shutoff valve 53 is opened when its own weight is such that the elastic force of the return spring 54 is overcome.
차단 밸브(53)가 개방되면 연료가 연료 탱크(70)로 주입되고, 연료 주입이 완료되면 상기 리턴 스프링(54)의 탄성에 의해 상기 차단 밸브(53)가 닫힘으로써 연료 탱크(70)의 증발 가스가 외부로 배출되는 것을 차단하게 된다. 이때, 상기 차단 밸브(53)는 상기 밸브 바디(51)의 외측에 위치되므로 연료 탱크(70) 측으로부터의 개방은 되지 않는다.When the shutoff valve 53 is opened, fuel is injected into the fuel tank 70. When the fuel injection is completed, the shutoff valve 53 is closed by the elasticity of the return spring 54, thereby evaporating the fuel tank 70. The gas is blocked from being discharged to the outside. At this time, since the shutoff valve 53 is located outside the valve body 51, the shutoff valve 53 is not opened from the fuel tank 70 side.
이와 같이, 본 고안의 연료 주입구 셧 오프 밸브는 차단 밸브가 밸브 바디의 외측에 위치되고 연료의 자중에 의해서만 개방되므로 증발 가스의 누설이 방지되고 차량의 충돌시에도 연료의 누출이 방지되어 화재 발생을 예방할 수 있는 이점이 있다.As such, the fuel inlet shut-off valve of the present invention has a shutoff valve located outside the valve body and is opened only by the self-weight of the fuel, thereby preventing the leakage of the evaporated gas and preventing the leakage of the fuel even in the event of a vehicle collision. There is an advantage that can be prevented.
