도면 중에 표시되는 도면부호 30은 본 발명에 의해 형성되는 연료차단밸브를 지시하는 것이고, 도면 부호 20은 본 발명에 의한 연료탱크를 지시하는 것인데, 도면부호 21은 설명의 편의상 연료탱크와 연결되는 각종의 파이프 및 호스를 통칭하여 연료파이프로 표시하기로 한다.Reference numeral 30 denoted in the drawing indicates a fuel shutoff valve formed by the present invention, and reference numeral 20 denotes a fuel tank according to the present invention, and reference numeral 21 denotes various types of fuel tanks for convenience of description. The pipes and hoses are referred to collectively as fuel pipes.

상기한 연료차단밸브(30)는 연료가 통과되는 연료파이프(21)의 도중에 연결되어, 차량의 충돌사고가 발생되었을 경우에 상기 연료차단밸브(30)가 기계적으로 작동되어 연료가 누출될 수 있는 연료라인의 도중이 차단되도록 구성되는 것이다. 이를 위해, 상기 연료차단밸브(30)는 연결구(31), 고무부시(33), 회전레버(36), 관성 볼(38) 등의 부품을 구성된다.The fuel cutoff valve 30 is connected in the middle of the fuel pipe 21 through which fuel passes, and when the collision accident of the vehicle occurs, the fuel cutoff valve 30 may be mechanically operated so that fuel may leak. It is configured to block the middle of the fuel line. To this end, the fuel shutoff valve 30 is composed of components such as a connector 31, rubber bush 33, rotary lever 36, inertial ball (38).

즉, 상기한 연결구(31)는 연료가 통과되는 연료라인을 이루는 각종 연료파이프(21)의 도중에 연결될 수 있도록 그 양측 끝단에 나사면 혹은 니플과 같은 연결부(31a)가 마련되고, 그 중간부 도중에 회전레버(36)의 도중에 끼워지기 위한 회전레버 끼움공(32)이 형성된다.That is, the connector 31 is provided with a connecting portion 31a, such as a screw surface or nipple, at both ends thereof so as to be connected in the middle of various fuel pipes 21 constituting the fuel line through which the fuel passes. The rotary lever fitting hole 32 for fitting in the middle of the rotary lever 36 is formed.

고무부시(33)는 상기한 연결구(31)의 내부에 길이방향으로 끼워지는 고무재의 원통관으로서, 충돌하중을 받지 않을 때는 회전레버(36)가 회전되지 못하도록 형상결합되어 있다가, 차량의 충돌에 의한 충돌하중이 전달되면 탄성변형되어 상기 회전레버(36)의 회전이 허용되도록 하기 위한 것이다. 그리고 상기한 고무부시(33)의 중간부에는 상기 연결구(31)의 도중에 마련된 회전레버 끼움공(32)과 일치된 상태로 상기 회전레버(36)의 도중이 끼워질 수 있도록 회전레버 끼움공(35)이 관통형성된다.The rubber bush 33 is a cylindrical tube of rubber material inserted into the connector 31 in the longitudinal direction. When the rubber bush 33 is not subjected to a collision load, the rubber lever 33 is shaped to prevent the rotation lever 36 from rotating, and the vehicle collides with the vehicle. When the impact load is transmitted by the elastic deformation is to allow the rotation of the rotary lever 36. And in the middle portion of the rubber bush 33, the rotary lever fitting hole so that the middle of the rotary lever 36 can be fitted in a state consistent with the rotary lever fitting hole 32 provided in the middle of the connector ( 35) is penetrated.

상기한 고무부시(33)의 회전레버 끼움공(35)에 그 도중이 끼워지는 회전레버(36)에는 초기상태에서 상기 연료파이프(21)로 연료가 흐를 수 있도록 하기 위한 연료통과공(37)이 형성되고, 상기 연료통과공(37)의 일측 끝단이 위치되는 외주면은 평평한 면이 되도록 하는 플랫면(36a)이 축방향으로 길게 형성된다.A fuel passage hole 37 for allowing fuel to flow into the fuel pipe 21 in an initial state in the rotary lever 36 in which the middle thereof is inserted into the rotary lever fitting hole 35 of the rubber bush 33. Is formed, the outer circumferential surface at which one end of the fuel passage hole 37 is located is formed with a flat surface (36a) long to be a flat surface in the axial direction.

그리고 상기한 회전레버(36)의 일측 끝단 상부에는 관성 볼(38)이 부착되는데, 상기 관성 볼(38)은 회전레버(36)에 원심력이 가해질 수 있도록 회전레버(36)와 소정 간격 떨어진 위치에 로드(39)로써 연결된다.In addition, an inertial ball 38 is attached to an upper portion of one end of the rotary lever 36, and the inertial ball 38 is spaced apart from the rotary lever 36 by a predetermined distance so that centrifugal force can be applied to the rotary lever 36. To the rod 39.

상기와 같이 각각 구성된 부품은 연결구(31)의 내부에 고무부시(33)를 끼우고, 상기 연결구(31)와 고무부시(33)에 형성된 회전레버 끼움공(32,35)을 통해 회전레버(36)를 가로질러 끼우게 된다. 이 때, 상기한 회전레버(36)의연료통과공(37)은 고무부시(34)의 관통공(34)에 일치되도록 하고, 플랫면(37)과 관성 볼(38)은 수직상으로 위치되도록 한다.Each of the components configured as described above is fitted with a rubber bush 33 in the interior of the connector 31, the rotary lever through the rotary lever fitting holes (32, 35) formed in the connector 31 and the rubber bush (33) 36) to fit across. At this time, the fuel passage hole 37 of the rotary lever 36 is to match the through hole 34 of the rubber bush 34, the flat surface 37 and the inertia ball 38 is positioned vertically Be sure to

그리고 상기한 고무부시(34)에 장착된 회전레버(36)가 이탈되지 않도록 하기 위해서 상기 회전레버(36)의 양측에는 고정 링(40)이 끼워진다. 이를 위해, 상기 회전레버(36)의 연료통과공(37) 양측에는 링홈(36b)이 형성되는 것이 바람직하다.In order to prevent the rotary lever 36 mounted on the rubber bush 34 from being separated, the fixing ring 40 is fitted to both sides of the rotary lever 36. To this end, it is preferable that ring grooves 36b are formed at both sides of the fuel passage hole 37 of the rotary lever 36.
