Description

원웨이밸브가 설치된 연료탱크{FUEL TANK WITH ONE-WAY VALVE}FUEL TANK WITH ONE-WAY VALVE}

본 발명은 원웨이밸브가 설치된 연료탱크에 관한 것으로, 보다 상세 하게는 연료탱크 하측면 전후에 일방향으로 흐름을 단속할 수 있는 원웨이밸브를 부설하여 연료공급의 안정성이 향상될 수 있도록 한 원웨이밸브가 설치된 연료탱크에 관한 것이다.The present invention relates to a fuel tank in which a one-way valve is installed, and more particularly, a one-way valve for intermittent flow in one direction before and after the lower side of the fuel tank to improve the stability of fuel supply. A fuel tank with a valve installed.

일반적으로 연료탱크는 연료를 저장하는 용기이며, 그 용량은 자동차의 용도나 구조에 따라 다르나 대략 1일 사용분( 30 ~ 70ℓ)을 기준으로 결정된다.In general, a fuel tank is a container for storing fuel, and its capacity is determined based on a daily use (30 to 70 liters), depending on the use or structure of the vehicle.

상기 연료탱크는 얇은 강판으로 만든 탱크 본체에 연료를 넣는 주입구(INLET PIPE), 드레인 플러그(DRAIN PLUG), 연료의 양을 알리는 연료계의 송신부(SENDER UNIT) 등이 부착되어 있고, 탱크 내부에는 주행시에 연료가 출렁거리는 것을 방지하고, 탱크의 강도를 높이기 위해 몇개의 간막이(SEPARATOR)가 용접되어 있다.The fuel tank has an inlet pipe for injecting fuel into a tank body made of a thin steel sheet, a drain plug, a drain unit for indicating the amount of fuel, and the like. Several separators are welded to prevent the fuel from slacking and to increase the strength of the tank.

내부면은 녹이 슬지 않도록 도금이 되어 있고, 탱크 윗면에는 브리이더 파이프(BREATHER PIPE)가 부착되어 연료의 액면이 변동하여 탱크안이 부압으로 되었을 때, 연료가 기화기로 공급되지 않거나, 바깥 온도의 상승으로 탱크안의 압력이 높아졌을 때, 연료가 새는 것을 방지된다.The inner surface is plated to prevent rust, and a breather pipe is attached to the upper surface of the tank so that when the liquid level of the fuel fluctuates and the tank is under negative pressure, the fuel is not supplied to the carburetor or the temperature rises. When the pressure in the tank rises, fuel leaks are prevented.

첨부된 도면의 도 1은 종래의 자동차용 연료탱크의 주입관을 도시한 사시도이다.1 of the accompanying drawings is a perspective view showing an injection tube of a conventional fuel tank for a vehicle.

도시된 바와 같이, 자동차의 연료탱크(1)의 하측 외주면에는 주입관(2)이 연통되어 외부로부터 연료가 공급된다.As shown, the injection pipe 2 is connected to the lower outer peripheral surface of the fuel tank 1 of the vehicle to supply fuel from the outside.

그러나, 상기와 같은 종래의 주입관(2) 부설된 연료탱크(1)는 다음과 같은 단점이 있었다.However, the fuel tank 1 installed in the conventional injection tube 2 as described above has the following disadvantages.

즉, 자동차가 전후 또는 좌우로 경사되어 운행할 시 주입관(2)이 하측 외주면에 설치되어 있기 때문에 상기 주입관(2)으로 연료가 빠져나가는 것은 방지 되지만, 내부에 계류중인 연료는 연료탱크(1) 내부로 유입될 수 없어 잔류연료만으로 운행을 해야 하기 때문에 자동차의 시동이 꺼질 수 있으며, 이러한 이유로 인하여 상기 주입관(2)을 최대한으로 하측으로 부설해야 한다는 제약이 따랐다.That is, since the injection pipe 2 is installed on the lower outer circumferential surface when the vehicle is inclined forward and backward or left and right, the fuel is prevented from escaping to the injection pipe 2, but the fuel pending therein is stored in the fuel tank ( 1) Since the vehicle cannot be introduced into the vehicle and the vehicle needs to be operated only with residual fuel, the starting of the vehicle may be turned off, and for this reason, the injection tube 2 should be placed to the lower side as much as possible.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 연료탱크 하측면 전후측에 일측방향으로 만 유동이 가능한 원웨이밸브를 각각 부설하여 어떠한 방향으로 경사진 도로를 주행하여도 연료가 연료탱크로부터 유출되지 않음은 물론, 상기 외부로부터 연료를 상기 연료탱크 내부로 유입시킬 수 있어 연료공급의 안정성을 향상시킬 수 있도록 한 원웨이밸브가 설치된 연료탱크를 제공함에 그 목적이 있다.The present invention was created in view of the above-described problems of the prior art as described above, the one-way valve that is possible to flow only in one direction on the front and rear sides of the fuel tank, respectively, the road inclined in any direction In addition, the fuel tank does not flow out of the fuel tank even when the vehicle is driven, and the fuel tank provided with a one-way valve is installed to improve fuel supply stability by allowing fuel to flow into the fuel tank from the outside. There is a purpose.

본 발명의 상술한 목적은 연료가 저장되는 본체와, 상기 연료탱크와 차체 외부를 연통시키는 연료 주입관이 이 연료탱크 하측에 부설된 자동차용 연료탱크에 있어서, 상기 연료탱크는 하부면 전후측에 각각 원웨이밸브가 부설되고 상기 주입관과 연결되어 유입된 연료가 유출되지 않게 구성함에 의해 달성된다.In the above-described object of the present invention, a fuel tank for an automobile in which a main body in which fuel is stored and a fuel injection pipe communicating with the fuel tank and the outside of the vehicle body are provided below the fuel tank, wherein the fuel tank is located at the front and rear sides of the lower surface. Each one-way valve is provided and is connected to the injection pipe is achieved by configuring the incoming fuel does not flow out.

이하에서는, 본 발명에 따른 바람직한 일 실시예를 첨부도면에 의거하여 보다 상세하게 설명한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail on the basis of the accompanying drawings.

본 실시예를 설명함에 있어, 서두에서 설명된 종래구성과 동일한 기능의 구성에 대해서는 동일부호를 사용하고, 가능한 중복되는 설명은 피하고 개선된 부분만을 주로 설명한다.In describing the present embodiment, the same reference numerals are used for the components having the same functions as those of the prior art described at the beginning, and only the improved parts will be mainly described without avoiding possible overlapping descriptions.

첨부된 도 2는 본 발명에 따른 자동차용 연료탱크의 사시도이다.2 is a perspective view of a fuel tank for a vehicle according to the present invention.

도시된 바와 같이, 본 실시예의 자동차용 연료탱크(3)는 장방체의 빈 용기이며 하측면 전후방향으로 각각 원웨이밸브(4)가 형성되어 주입관(5)과 연결된다.As shown, the vehicle fuel tank 3 of the present embodiment is an empty container of a rectangular shape, and one-way valves 4 are formed in the lower and front directions, respectively, and are connected to the injection pipe 5.

상기 각각의 원웨이밸브(4)가 삽입되는 상기 연료탱크(3)의 양측 접합부는 상기 원웨이밸브(4)의 마개(6)가 상하 이동이 용이하도록 계단식으로 절곡되어 있다.Both junctions of the fuel tank 3 into which the one-way valve 4 is inserted are bent stepwise so that the stopper 6 of the one-way valve 4 can be easily moved up and down.

상기와 같이, 주입관(5)을 통하여 연료가 연료탱크(3) 내부로 유입된 후 자동차가 주행중에 경사되어도, 상기 연료탱크(3)에 충만된 연료는 원웨이밸브(4)에 의하여 주입관(5)으로는 역류되지 않으며, 이러한 것에 의하여 연료냉크(3) 내부의 연료가 완전소모될 때 까지 연료를 엔진부(미도시)에 공급할 수 있다. As described above, even when the vehicle is inclined while driving after the fuel flows into the fuel tank 3 through the injection pipe 5, the fuel filled in the fuel tank 3 is injected by the one-way valve 4. It does not flow back into the pipe 5, and by this, fuel can be supplied to an engine part (not shown) until the fuel inside the fuel cool 3 is completely consumed.

이상에서 상세히 설명한 바와 같이, 본 발명은 연료탱크 하부면 전후측에 일측방향으로만 소통되는 원웨이밸브를 각각 삽입설치하여 탱크내부에 존재하는 연료를 모두 엔진부에 공급할 수 있음은 물론, 주입관에 잔존해 있는 연료가 연료탱크 내부로 유입된 것을 유출되지 않게 하여 연료공급의 안정성을 향상시킬 수 있는 효과를 제공한다.As described in detail above, in the present invention, the one-way valve communicating only in one direction is inserted into the fuel tank lower surface front and rear, respectively, to supply all the fuel present in the tank to the engine, as well as the injection pipe. It is possible to improve the stability of fuel supply by preventing the remaining fuel from flowing into the fuel tank.
