연료탱크의 연료 유동 방지장치{Preventing device to fuel rolling for fuel tank}Preventing device to fuel rolling for fuel tank

본 발명은 연료탱크의 연료 유동 방지장치에 관한 것으로서, 특히 차량의 급정거 또는 급출발시 연료가 출렁이려고 할때 연료의 출렁임이 방지되고, 이에의해 연료의 출렁임에 의해 발생하는 소음을 감소시킬 수 있도록 한 연료탱크의 연료 유동 방지장치에 관한 것이다.The present invention relates to an apparatus for preventing fuel flow of a fuel tank, and particularly, when fuel is about to run out during a sudden stop or sudden start of a vehicle, fuel run out is prevented, thereby reducing noise generated by run out of the fuel. A fuel tank prevention device for a fuel tank.

연료탱크라 함은 자동차의 엔진에 공급하기 위한 일정양의 연료를 저장하는 것으로서, 차량의 크기나 모양에 따라 여러가지 형태의 연료탱크가 제공되고 있다.The fuel tank stores a certain amount of fuel for supplying an engine of a vehicle, and various types of fuel tanks are provided according to the size and shape of the vehicle.

이러한 연료탱크에는 항시 일정양의 연료가 저장되어 있기 때문에 차량이 급출발을 하거나 급정거할때 연료탱크 내의 연료가 출렁이면서 심한 소음이 발생하게되어 차량의 전체적인 품질이 떨어지는 원인이 되고 있다.Since a certain amount of fuel is always stored in the fuel tank, when the vehicle starts or stops suddenly, fuel in the fuel tank slumps and generates a lot of noise, which causes the overall quality of the vehicle to decrease.

도 1 은 상기와같은 문제점의 해결을 위해 제공되는 종래의 연료 유동 방지장치를 도시한 것으로서,1 illustrates a conventional fuel flow preventing apparatus provided for solving the above problems,

연료탱크(1)의 내부에 복수의 배플(2)을 수직으로 세워 설치하고, 각각의 배플(2)에 복수개의 유동홀(3)을 형성시켜 이 유동홀(3)을 통해 연료의 움직임이 가능해지도록 한 것이다.A plurality of baffles 2 are installed vertically inside the fuel tank 1, and a plurality of flow holes 3 are formed in each baffle 2 to move the fuel through the flow holes 3. It was made possible.

상기와같은 종래의 연료 유동 방지장치는 차량이 급정거 또는 급출발할때 연료탱크 내에서 연료의 출렁임 발생시 상기 유동홀(3)을 통해서만 연료가 움직이게 되므로 연료의 심한 출렁임을 방지할 수 있게된다.The conventional fuel flow prevention device as described above can prevent the heavy rung of the fuel because the fuel moves only through the flow hole 3 when the runout of the fuel occurs in the fuel tank when the vehicle is suddenly stopped or started.

그러나, 종래의 연료 유동 방지장치는 연료탱크 내의 수위가 유동홀(3) 부근(예를들면 A 위치)에 존재할 경우에는 출렁이는 연료들이 상기 유동홀(3)을 통해 자유롭게 유동되면서 출렁임현상이 발생하게되어 연료 출렁임에 의한 소음이 발생하게되는 문제점이 있었다.However, in the conventional fuel flow preventing device, when the water level in the fuel tank is located near the flow hole 3 (for example, the A position), the floating fuel flows freely through the flow hole 3, causing the phenomenon of rumble. There was a problem that the noise caused by the fuel rumble occurs.

따라서, 상기 문제점을 해결하기 위한 본 발명은 배플에 형성되어있는 복수의 유동홀 내측으로 연료의 움직임방향에 대해 저항으로 작용하는 저항수단을 형성하므로서, 차량의 급정거 또는 급출발시 연료가 출렁이려고 할때 상기 저항수단에 의해 연료의 출렁임이 방지되고, 이에의해 연료의 출렁임에 의해 발생하는 소음을 감소시킬 수 있도록 한 연료탱크의 연료 유동 방지장치를 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is to form a resistance means that acts as a resistance to the direction of movement of the fuel inside the plurality of flow holes formed in the baffle, so that the fuel is going to run during sudden stop or start of the vehicle It is an object of the present invention to provide a fuel flow preventing device of a fuel tank in which fuel resistance is prevented by the resistance means, thereby reducing noise generated by fuel consumption.

상기 목적달성을 위한 본 발명은,The present invention for achieving the above object,

이하, 첨부된 도면 도 2 내지 도 4 를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 2 to 4.

상기 도면에 의하면, 도면부호 10 은 연료탱크를 나타내며, 이 연료탱크(10)의 내부에는 복수의 배플(11)이 수직으로 세워져 설치되어 있다.According to the drawing, reference numeral 10 denotes a fuel tank, and a plurality of baffles 11 are vertically installed inside the fuel tank 10.

각각의 배플(11)에는 복수의 유동홀(12)이 형성되는데, 중앙의 유동홀(12)이 직경이 가장크고, 그 외각으로 형성되는 유동홀(12)의 직경은 중앙의 것보다 작게 형성된다.Each baffle 11 is formed with a plurality of flow holes 12, the central flow hole 12 has the largest diameter, the diameter of the flow hole 12 formed in the outer shell is formed smaller than the central one do.

본 발명에서는 상기 유동홀(12)의 내측으로 연료의 움직임방향에 대해 저항으로 작용하여 연료의 출렁임을 최대한 억제하는 저항수단(20)을 형성하였다.In the present invention, the resistance means 20 that acts as a resistance to the direction of movement of the fuel to the inside of the flow hole 12 to suppress the runoff of the fuel as much as possible.

상기 저항수단(20)은 도 3 과 도 4 에 도시된 바와같이 유동홀(12)의 내주면으로부터 중심을 향하도록 다수의 날개(21,22)를 돌출시켜 이 날개(21,22)들이 연료의 움직임에 대해 저항으로 작용하도록 하였다.As shown in FIGS. 3 and 4, the resistance means 20 protrudes the plurality of wings 21 and 22 toward the center from the inner circumferential surface of the flow hole 12 such that the wings 21 and 22 are formed of fuel. It acts as a resistance to movement.

이때, 상기 날개(21,22)들은 배플(11)을 중심으로 하여 양측으로 일정각도 확개되도록 하되, 이웃하는 날개(21,22)의 경사방향이 서로 반대가 되도록 하는 것이 바람직하다.At this time, the wings (21, 22) are to be extended to a predetermined angle to both sides around the baffle (11), it is preferable that the inclined direction of the adjacent wings (21, 22) are opposite to each other.

즉, 도 4 에 도시된 바와같이 임의의 날개(21)를 배플(11)의 좌측으로 일정각도 확개되도록 형성하였다면, 그와 이웃하는 날개(22)를 배플(11)의 우측으로 일정각도 확개되도록 하므로서, 연료탱크(10) 내에서의 연료 유동시 상기 날개(21,22)들이 저항으로 작용하므로서 연료가 날개(21,22)의 사이 사이를 통해 유동하게 되어 그만큼 연료의 움직임량이 감소하게되는 것이다.That is, as shown in FIG. 4, if a predetermined blade 21 is formed to extend a predetermined angle to the left side of the baffle 11, the neighboring wing 22 is extended to a certain angle to the right side of the baffle 11. Thus, when the fuel flow in the fuel tank 10, the blades (21, 22) act as a resistance so that the fuel flows between the blades (21, 22) to reduce the amount of movement of the fuel by that amount .

이와같이 구성되는 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

본 발명의 동작설명은 연료탱크(10) 내부에 연료의 수면이 A위치인 경우를 예로하여 설명하기로 한다.The description of the operation of the present invention will be described by taking an example where the surface of the fuel in the fuel tank 10 is the A position.

연료탱크(10) 내부에 연료가 저장된 상태에서 차량이 급정거하거나 급출발하게되면, 연료탱크(10) 내부의 연료들은 관성에 의해 도면상의 좌측 또는 우측으로 급격히 이동하려고 한다.When the vehicle suddenly stops or starts quickly in a state where fuel is stored in the fuel tank 10, the fuel in the fuel tank 10 tries to move rapidly to the left or right side of the drawing due to inertia.

상기 설명과같이 연료가 연료탱크(10) 내에서 좌우측으로 움직이려할때 본발명에서는 유동홀(12)의 내측으로 형성되어 있는 다수의 날개(21,22)들이 저항으로 작용하면서 연료의 움직임을 최대한 억제하게 된다.As described above, when the fuel tries to move left and right in the fuel tank 10, in the present invention, the plurality of wings 21 and 22 formed inwardly of the flow hole 12 act as a resistance to maximize the movement of the fuel. Will be suppressed.

따라서, 차량이 급정거 또는 급출발하더라도 연료의 출렁임현상이 크게 발생하지 않게되어 소음을 현저히 감소시킬 수 있게되는 것이다.Therefore, even if the vehicle stops or starts suddenly, the runoff of the fuel does not occur significantly, thereby significantly reducing the noise.

이상에서 설명한 바와같이 본 발명은 배플에 형성되어있는 복수의 유동홀 내측으로 연료의 움직임방향에 대해 저항으로 작용하는 저항수단을 형성하므로서, 차량의 급정거 또는 급출발시 연료가 출렁이려고 할때 상기 저항수단에 의해 연료의 출렁임이 방지되고, 이에의해 연료의 출렁임에 의해 발생하는 소음을 감소시킬 수 있도록 한 연료탱크의 연료 유동 방지장치를 제공하는 효과를 기대할 수 있다.As described above, the present invention forms a resistance means that acts as a resistance to the movement direction of the fuel inside a plurality of flow holes formed in the baffle, so that the resistance when the fuel is about to run during sudden stop or start of the vehicle. By the means, it is possible to anticipate the effect of providing a fuel flow preventing device of the fuel tank, in which fuel fluctuations are prevented, thereby reducing noise generated by the fuel fluctuations.
