Abstract

흡입 분류 펌프(20)는 자동차의 연료 저장 탱크 내에 설치되어 있고, 이 흡입 분류 펌프는 연료를 용기(12)내로 반송하는 역할을 하고 이 용기(12)로부터 반송 장치가 연료를 흡입한다. 흡입 분류 펌프(20)는 연료 도관(18)에 접속된 노즐(22)과 이 노즐로부터 간격을 두고 그것의 하류에 설치된 혼합관(26)을 구비하고 있다. 그 경우 혼합관(20)과 노즐(22)과의 사이에 연료 저장 탱크(10)로의 개구(27)가 형성되어 있다. 이 혼합관(26)은 용기(12)의 벽(13)을 관통하고 있고 또한 용기(12)내에 위치하는 그것의 단부 영역(28)의 곳에서 그것의 주위 범위에 슬릿 형상의 개구(30)를 구비하고 있다. 노즐(22)로부터 유출한 연료는 이것이 현저히 가열되어 있는 경우에는 증발하고 그 결과 기포가 형성되고 이 기포가 혼합관(26)내에도 나타난다. 이 기포는 슬릿(30)에 의해 유출할 수 있고 그 결과 흡입 분류 펌프(20)의 운전시 기포에 의해 악영향을 받지 아니하거나 또는 약간 밖에 악영향을 받지 아니한다.The suction fractionation pump 20 is installed in a fuel storage tank of an automobile, and this suction fractionation pump serves to convey fuel into the container 12, from which the conveying device inhales fuel. The suction fractionation pump 20 has a nozzle 22 connected to the fuel conduit 18 and a mixing tube 26 provided downstream of the nozzle at a distance from the nozzle. In that case, the opening 27 to the fuel storage tank 10 is formed between the mixing pipe 20 and the nozzle 22. This mixing tube 26 penetrates the wall 13 of the container 12 and also has a slit-shaped opening 30 in its circumferential range at its end region 28 located within the container 12. Equipped with. The fuel flowing out of the nozzle 22 evaporates when it is significantly heated, and as a result, bubbles are formed, which also appear in the mixing pipe 26. This bubble can flow out by the slit 30 and as a result is not adversely affected by the bubbles in operation of the suction fractionation pump 20 or only slightly adversely.
