Abstract

목적 : 급유 파이프를 가공할 필요없이 취부자유도를 크게 하고 연료의 압력에 의하여 변체가 출렁거리지 않는 연료 역류방지구를 얻는다.Purpose: Increases the mounting freedom without the need to process the oil supply pipe and obtains a fuel backflow prevention device that does not drift due to the pressure of the fuel.

구성 : 통체(18)는 연료탱크에 끼워넣어진 급유파이프에 트인구멍에 끼워넣어 고정된다. 이 때문에 급유파이트로 가공할 필요가 없게 된다. 통체(18)인 트인 구멍에는 개·폐 가능한 변체(30)가 축 지지되어 있으며, 통체(18)의 트인구멍을 밀폐할 수 있도록 되어 있다. 따라서 종래의 추식 역류방지기구에 비교하면 중량과의 관계를 고려할 필요가 없으므로 급유파이프의 취부자유도가 커진다.Composition: The cylinder 18 is fixed by being inserted into a hole drilled into an oil supply pipe fitted into a fuel tank. This eliminates the need for machining with lubrication pipes. The open / closeable deformable body 30 is axially supported by the open hole of the cylinder 18, and the open hole of the cylinder 18 can be sealed. Therefore, compared with the conventional fallback prevention mechanism, it is not necessary to consider the relationship with the weight, so the freedom of mounting of the lubrication pipe is increased.
