Abstract
Description
Claims (4)
- 연료탱크(1)의 내부에 설치되고 하단부에 리저브컵(6)이 구비되어 리저브컵(6)의 내부의 연료를 엔진으로 이송하며, 압력조절을 위해 일부의 이송연료를 회수관(7)을 통해 리저브컵(6) 내부로 리턴시키는 연료공급모듈에 있어서,상기 회수관(7)의 끝단에 결합되어 리턴연료를 리저브컵(6)의 내부로 분사하며, 길이구간 중 일부가 분리됨에 의해 다단노즐(33)로 형성되어 노즐(31, 32) 사이에서 흡입력을 발생시키는 진공노즐(30)과;상기 리저브컵(6)의 하단부에 흡입구(41)가 형성되고, 흡입구(41)와 진공노즐(30)의 흡입력이 발생되는 길이구간에 연통되도록 결합되어, 상기 연료탱크(1) 바닥면에 잔류하는 연료의 흡입진행로가 되며 상기 리저브컵(6) 내부의 연료가 역류되지 못하도록 하기 위해 리저브컵(6)의 바닥면에서 돌출형성되되, 상기 진공노즐(30)의 흡입력이 발생되는 길이구간에 연통되도록 결합될 때, 연료누출 및 부압형성을 위해 진공노즐(30)과의 결합지점에 O-링(36)이 개재되어 구성되는 흡입라인(40)을 포함하는 것을 특징으로 하는 연료공급모듈의 제트펌프 구조.
- 제 1 항에 있어서, 상기 흡입라인(40)은연료의 안정적인 흡입을 위해 진공노즐(30)의 끝단이 내측으로 헐거움 끼워맞춤 결합에 의해 삽입되어 구성된 것을 특징으로 하는 연료공급모듈의 제트펌프 구조.
