Abstract

전동연료펌프에 있어서, 펌프케이싱과 임펠러와의 마찰저항을 작게해서 모터의 회전수저하, 소비전력의 증대를 방지하고 토출효율이 좋은 전동연료펌프를 제공한다.
임펠러(1)를 미끄러져 움직이는면(3a), (16a)에서 지지하는 펌프케이싱(17)의 펌프실출구(6)와 대향하는 쪽의 미끄러저 움직이는 면(16a)의 펌프실출구(6) 근방에서 펌프실(4)의 내주측에 임펠러(1)와 미끄러저 움직이는 면(16)사이의 간격보다 큰 닿지않게둔 간격(16b)을 형성한다.

Description

전동연료펌프
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 이 발명의 실시예 1에 있어서의 전동연료펌프를 일부 파단해서 표시하는 구성도, 제2도는 제1도에 있어서의 선 Ⅱ-Ⅱ에 따른 단면도, 제3도는 제2도에 있어서의 선 Ⅲ-Ⅲ에 따른 단면도.

Claims (1)

  1. 원판상의 외주부에 날개홈부를 갖는 임펠러와, 이 임펠러의 양측면과의 미소간격으로 대향해서 상기 임펠러를 지지하고있는 미끄러져움직이는 면을 형성하는 동시에 상기 미끄러져움직이는 면의 외주측에서 상기 임펠러의 외주연부에 따라 뻗어있는 원호대(圓弧帶)상의 펌프실을 형성하고, 또 상기 원호대상의 일단부에 연료흡입구를 타단부에 펌프실출구에 설치한 펌프케이싱과, 상기 임펠러를 회전구동하는 모터부로 구성된 전동연료펌프에 있어서, 상기 펌프실출구와 대향하는 쪽의 상기 미끄러져움직이는 면의 상기 펌프 출구근방에서 상기 펌프실의 내주측에 상기 미소간격보다 큰 간격을 형성한 것을 특징으로 하는 전동연료펌프.
    ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.
