본 고안은 연료탱크 내의 연료량을 나타내는 연료유량계에 관한 것으로, 특히 쏠림되는 연료탱크내의 유면을 부유하는 부구의 움직임을 제한하여서 오동작없이 동작할 수 있도록 한 연료유량계에 관한 것이다.The present invention relates to a fuel flowmeter indicating the amount of fuel in a fuel tank, and more particularly, to a fuel flowmeter capable of operating without malfunction by limiting the movement of floating floats on the oil level in the fuel tank being pulled out.
종래의 연료유량계는 크게 지침식과 경고등식으로 분류되고, 지침식은 코일 서미스터식과 바이메탈식으로 나뉘어지는데, 코일 서미스터식은 제1도에 도시한 바와 같이 연료탱크안의 연료가 많고 적음에 따라 대응되어 뜨임되는 부구(5)의 동작에 의해 코일(L1 또는 L2)에 형성된 자장의 상대적 크기에 대응하여 회동하는 지침을 이용한 것이고, 바이메탈식은 제2도에 도시한 바와 같이 연료의 유면 높이에 따라 동작하는 부구(5)에 의해 열선에 흐르는 전류의 통전시간에 비례하여 바이메탈의 힘에 의해 회동하는 지침을 이용한 서보스탯 바이메탈식과, 제3도에 도시한 바와 같이 부구(5)의 높이 위치 및 가변저항기에 흐르는 전류의 양에 따라 지침이 동작하도록 한 바이메탈 저항식이 있으며, 경고등식은 연료탱크 내의 연료 유면 높이를 따라 움직이는 부구가 스위치의 접점이 닫혀 경고등이 점등되도록 한 것이다.Conventional fuel flowmeters are largely classified into guide and warning lights, and the guide equations are divided into coil thermistor and bimetal. By using the guidance of rotating in response to the relative magnitude of the magnetic field formed in the coil (L1 or L2) by the operation of (5), the bimetal formula is a buckle (5) that operates in accordance with the oil level of the fuel as shown in FIG. Servostat bimetal formula using a guide that rotates by bimetal force in proportion to the energization time of the current flowing in the heating wire, and the height of the ball 5 and the current flowing through the variable resistor as shown in FIG. There is a bimetallic resistance that allows the guide to operate according to the quantity, and a warning light is used to move the fuel along the level The contacts of the switch will be closed so that a warning lamp lights up.
이상에서 언급한 종래의 연료유량계는 모두 연료탱크 내에 연료의 유면 높이에 따라 뜨임되는 부구(5)를 공통적으로 갖고 있다. 따라서 차량에 부설된 연료탱크가 차량의 진동 또는 제동동작에 따른 탱크내의 연료쏠림에 의해 부구가 심하게 흔들리는 현상으로 연료유량계의 지침동작이 불확실한 경우가 발생되어 특히, 급제동시나 급출발시에 연료경고등에 점등이 되는 오동작 현상이 나타난다.The above-mentioned conventional fuel flowmeters all have a buckle 5 which is tempered in accordance with the oil level of the fuel in the fuel tank in common. Therefore, the fuel tank attached to the vehicle is a phenomenon that the guideline of the fuel flow meter is unstable due to the shaking of the mouth due to the fuel in the tank due to the vibration of the vehicle or the braking action. The malfunction phenomenon that appears.
따라서 본 고안은 상기와 같은 점을 감안하여 안출된 것으로, 그 목적은 차량의 흔들림이나 급제도 및 급출발시 연료유량계가 오동작 하는 것을 방지하는 연료유량계를 제공함에 있다.Accordingly, the present invention has been made in view of the above, and its object is to provide a fuel flowmeter which prevents the fuel flowmeter from malfunctioning during shaking or feeding and sudden start of the vehicle.
상기의 목적을 달성하기 위한 본 고안의 구체적인 수단은, 상단이 확대 개방되고 하단이 폐쇄된 원통봉에 부구를 수납하게 하고, 이 원통봉의 하부에 오리피스를 갖는 파이프를 접속하여서 달성된다.A specific means of the present invention for achieving the above object is achieved by allowing the upper part to be housed in a cylindrical rod with an open end and a lower end closed, and connecting a pipe having an orifice to the lower part of the cylindrical rod.
이하, 본 고안의 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제4도에 도시한 바와 같이 연료탱크(10)에 연료유량계의 부구(11)가 넣어지는 하단이 폐쇄되고 상부가 개구된 원통봉(12)이 부설되고, 이 원통봉(12)의 하부 일측에 오리피스(13)를 갖는 소직경의 파이프(14)가 접속되어 있다.As shown in FIG. 4, a cylindrical rod 12 having a lower end and an upper opening thereof is placed in the fuel tank 10, and a lower side of the cylindrical rod 12 is disposed. The small-diameter pipe 14 having the orifice 13 is connected to it.
이와 같이 연료유량계의 부구(11)를 원통봉(12)에 넣어서 원통봉(12)의 유면에 부상하도록 한 상태에서, 차량의 흔들림이나 급제동 및 급출발시 연료탱크(10)가 한쪽으로 쏠리게 되면 유면은 일측으로 기울어지게 된다. 이때 부구(11)는 원통봉(12)의 내벽에 접촉됨으로 흔들림이 방지된다. 더욱이 기울어진 유면에 의해 부구가 받는 급격한 압력변화를 파이프(14)에 구비된 오리피스(13)가 댐핑기능으로 억제하게 함으로써 부구(11)가 급동작하는 일은 없다.Thus, the fuel tank 10 is pushed to one side during the shaking, sudden braking, and sudden start of the vehicle while the float 11 of the fuel flow meter is placed in the cylindrical rod 12 to float on the oil surface of the cylindrical rod 12. Is tilted to one side. At this time, the buoy 11 is in contact with the inner wall of the cylindrical rod 12 is prevented from shaking. Furthermore, the orifice 11 does not suddenly operate by causing the orifice 13 provided in the pipe 14 to suppress the sudden pressure change received by the inclined oil surface by the damping function.
따라서, 부구(11)는 유면의 기울기 변화에 큰 변화없이 정위치를 차지하게 됨으로 연료유량계가 오동작하는 것을 방지할 수 있다.Therefore, the buoy 11 can be prevented from malfunctioning because the fuel flowmeter occupies the correct position without a great change in the inclination change of the oil level.
한편, 상기 파이프(14)에 대체하여 원통봉(12)의 하부 일측에 직접 오리피스를 구성하여도 좋다.Alternatively, the orifice may be configured directly on the lower side of the cylindrical rod 12 in place of the pipe 14.
이상에서와 같이 연료탱크내에 부상하는 부구를 오리피스를 갖는 파이프에 수납시켜 구성함으로써 차량의 진동이나 흔들림은 물론 급제동 및 급가속시 연료유량계가 오동작하는 것을 방지할 수 있다.As described above, by storing the buoys floating in the fuel tank in a pipe having an orifice, it is possible to prevent the fuel flow meter from malfunctioning during sudden braking and rapid acceleration as well as vibration and shaking of the vehicle.
