Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
본 고안은 자동차의 연료탱크에 주유할 때 입출관을 통해 공기가 유출되는 것을 차단하기 위한 것으로, 입출관의 일측에 솔레노이드밸브를 설치하여 주유중에 입출관을 차단시켜 연료의 과충전을 방지하기 위한 자동차 연료탱크의 입출관 차단장치에 관한 것이다.The present invention is to prevent the air flow through the inlet and outlet pipe when refueling the fuel tank of the car, by installing a solenoid valve on one side of the inlet and outlet pipe to prevent the overcharge of fuel The present invention relates to a fuel tank shutoff device.
연료탱크(1)는 연료를 저장하는 것으로 첨부도면 제1도와 같이 탱크본체(9), 주입구(4), 연료파이프(6), 연료리턴파이프(7) 등으로 구성되어 있으며, 탱크본체(9) 내면은 녹슬지 않도록 방청처리 되어 있다.The fuel tank 1 stores fuel and is composed of a tank main body 9, an injection port 4, a fuel pipe 6, a fuel return pipe 7, and the like as shown in FIG. ) The inner surface is rustproofed to prevent rust.
입출관(8)은 공기가 탱크본체(9) 내부로 유입되거나 탱크본체(9) 내부에 있는 연료의 증발가스가 흐를 수 있도록 형성된 관이고, 중간에 체크밸브(20와 캐니스터(3)가 설치되어 있다.The inlet and outlet pipe 8 is a tube formed so that air can flow into the tank body 9 or the evaporated gas of fuel in the tank body 9 can flow, and a check valve 20 and a canister 3 are installed in the middle. It is.
즉, 탱크본체(9) 내의 증기압이 상승하면 체크밸브(2)가 열리고, 증발가스는 캐니스터(3)내로 흘러들어 간다.That is, when the vapor pressure in the tank main body 9 rises, the check valve 2 opens and the boil-off gas flows into the canister 3.
엔진 정지중에는 퍼지 컨트롤 밸브가 닫혀 있기 때문에 증발가스는 엔진 쪽으로 흐르지 않고 캐니스터(3)내에 멈추게 되고 가솔린은 활성탄에 흡착되어 공기만이 대기중으로 방출된다.Since the purge control valve is closed while the engine is stopped, the boil-off gas does not flow to the engine but is stopped in the canister 3, and gasoline is adsorbed on the activated carbon and only air is released into the atmosphere.
엔진이 작동하면 엔진의 흡입 부압에 의해 퍼지 컨트롤 밸브가 열리고, 대기가 캐니스터(3)를 통과할 때 흡착된 가솔린을 따라 기화기에 흡입된다. 연료 리턴파이프(7)는 연료파이프(6)를 통해 엔진으로 흘러간 연료가 다 소모되지 않고 약간의 잔유량이 남았을 대 탱크본체(9)로 다시 흘러들어 올 수 있도록 설치한 것이다.When the engine is operated, the purge control valve is opened by the intake negative pressure of the engine, and when the atmosphere passes through the canister 3, it is sucked into the vaporizer along with the adsorbed gasoline. The fuel return pipe 7 is installed so that the fuel flowing into the engine through the fuel pipe 6 is not exhausted and may flow back into the tank body 9 when a small amount of residual oil remains.
주입구(4)에 주유건을 삽입했을 대 주유건은 공기유통관(a)의 입출구(b)를 통과한 상태에서 주유건에서 기름이 유출되어 주유관(5)를 타고 탱크본체(9) 내로 기름이 채워지게 된다.When oil is inserted into the inlet (4), the oil is leaked from the oil in the state passing through the inlet and outlet (b) of the air flow pipe (a), and the oil flows into the tank body (9) through the oil supply pipe (5). Will be filled.
공기유통관(a)은 주유건을 주입구(4)에 삽입한 다음 주유관(5)으로 기름을 유입할 때 탱크본체(9)의 공기가 공기유통관(a)을 타고 외부로 빠져 나갈 수 있도록 한 것으로 진공 상태를 방지하기 위한 것이다.The air distribution pipe (a) inserts the gas gun into the inlet (4), and when the oil flows into the oil supply pipe (5) so that the air of the tank body (9) can escape through the air distribution pipe (a) to the outside This is to prevent the vacuum state.
주행중 엔진의 구동으로 연료가 소비되는 만큼 공기가 입출관(8)을 따라 탱크본체(9)로 유입되어 탱크본체(9) 내외의 대기압을 맞추게 되는 것이다.As fuel is consumed by driving the engine while driving, air flows into the tank main body 9 along the inlet / outlet tube 8 to adjust the atmospheric pressure inside and outside the tank main body 9.
탱크본체(9)에 연료를 주유할 때 어느정도의 여유공간을 주고 연료를 채워야 한다. 왜냐하면, 탱크본체(9)에 연료를 채운 다음 주행시 연료의 마챨열로 인한 팽창으로 탱크본체(9)에 압력이 가해지고, 이때 이 압력으로 탱크본체(9)에 균열이 발생될 수 있기 때문이다.When fuel is supplied to the tank body (9), a certain amount of space should be provided and the fuel filled. This is because, when the tank body 9 is filled with fuel, pressure is applied to the tank body 9 due to expansion caused by the heat of the fuel during driving, and at this time, cracks may occur in the tank body 9 at this pressure. .
그러나, 종래 연료탱크(1)의 탱크본체(9)에 주유할 때 입출관(8)을 통해 소량의 공기가 유출됨에 따라 연료가 탱크본체(9)에 가득 채워진 상태에서 탱크본체(9)에 연료를 주입하는 사람이 소량급유를 과다하게 실시할 경우에 연료가 과충전 되어 입출관(8)의 체크밸브(2)까지 차는 경우 증발가스가 캐니스터(3)로 잘 유출되지 않는 문제가 있었다.However, when a small amount of air flows out through the inlet and outlet pipe 8 when filling the tank main body 9 of the conventional fuel tank 1, the tank main body 9 is filled with the fuel in the tank main body 9. When a person injecting fuel excessively refuels, when the fuel is overcharged and filled up to the check valve 2 of the inlet and outlet pipe 8, there is a problem that the evaporated gas does not flow out to the canister 3 well.
또한, 탱크본체(9)에 연료가 가득 채워진 상태에서 주행시 연료의 팽창으로 탱크본체(9)에 압력이 가해져 탱크본체(9)에 손상을 줄 수 있는 문제가 있었다.In addition, there is a problem that the tank main body 9 may be damaged due to the expansion of the fuel when the tank main body 9 is filled with fuel, causing damage to the tank main body 9.
본 고안은 상기한 종래 자동차의 연료탱크가 지닌 문제를 해결하기 위하여 안출된 것으로, 주유중에 입출관을 차단함으로써 연료가 가득 채워진 상태에서 소량 급유에 의해 발생할 수 있는 연료의 과충전을 미연에 방지할 수 있는 자동차 연료탱크의 입출관 차단장치를 제공하고자 함에 고안의 목적이 있다.The present invention has been devised to solve the problems of the fuel tank of the conventional vehicle, it is possible to prevent the overcharging of fuel that may be caused by a small amount of fuel in a state filled with fuel by blocking the entry and exit pipe during the refueling. An object of the present invention is to provide an inlet / outlet blocker of an automotive fuel tank.
상기와 같은 목적을 실현하기 위한 본 고안은 탱크본체와 체크밸브 사이의 입출관에 솔레노이드밸브를 설치하고, 주입구의 내측 부위에 센서를 설치하며, 센서와 솔레노이드밸브 사이에는 전자제어장치가 설치되어 센서와 솔레노이드밸브간에 전자제어장치에 의해 명령을 주고 받을 수 있도록 설치한 것이다.The present invention for realizing the above object is to install a solenoid valve in the inlet and outlet pipe between the tank body and the check valve, the sensor is installed in the inner portion of the inlet, the electronic control device is installed between the sensor and the solenoid valve It is installed so that command can be exchanged between and solenoid valve by electronic control device.
따라서, 본 고안은 연료탱크의 주입구에 주유할 때 입출관을 차단함으로써 연료가 가득 채워진 상태에서 소량 급유에 의해 발생할 수 있는 연료의 과충전을 미연에 방지할 수 있는 것이다.Therefore, the present invention is capable of preventing overcharging of fuel which may be caused by a small amount of fuel supply in a state where the fuel is full by blocking the entry and exit pipe when filling the inlet of the fuel tank.
