Description
図1はこの発明の実施の形態1における燃料ポンプを示す断面図、図2はケーシングカバーを示す平面図であり、図1における線A−Aに沿う断面図に相当する。また、図3は空気排出口および空気排出弁機構を、図4はベーパ排出口およびベーパ排出弁機構を示しており、それぞれ図2において、線B−B、線C−Cに沿う断面図である。なお、図5〜7は特性図であり、図5は、この実施の形態1の効果をより明確にするために、比較例とともに燃料吸入能力を測定した結果を、図6および7は、ノズル形ベンチュリ計での流量計算式を使用した試算結果を、それぞれ示しており、詳述すると、図6は空気排出口の穴径と空気通過時の圧力損失を、図7は空気排出口の穴径と燃料の排出流量を、それぞれ示している。
図8はこの発明の実施の形態2における図3相当図である。この実施の形態2は吸気防止弁機構130を付加した以外は、実施の形態1(図3)と実質的に同一であるため、この吸気防止弁機構130を中心に説明する。
54 終端、100 燃料、110 空気排出口、111 空気排出弁機構、
120 ベーパ排出口、121 ベーパ排出弁機構、130 吸気防止弁機構。
Claims (5)
- 回転体の回転により燃料吸入口から吸い上げた燃料を上記回転体の周囲に形成されているポンプ流路で加圧するとともに、上記ポンプ流路の終端近傍に空気排出口と、この空気排出口からの燃料の排出を防止する空気排出弁機構を備えた燃料ポンプにおいて、
上記空気排出口よりも上記回転体の反回転側にベーパ排出口と、このベーパ排出口からの空気の吸入を防止するベーパ排出弁機構を備え、上記ポンプ流路の燃料が加圧されると直ちに、上記空気排出弁機構は閉弁させ、上記ベーパ排出弁機構は開弁させるようにしたことを特徴とする燃料ポンプ。 - 空気排出弁機構の閉弁とベーパ排出弁機構の開弁がほぼ同時に行われるように構成したことを特徴とする請求項1に記載の燃料ポンプ。
- 空気排出弁機構の閉弁より若干遅れてベーパ排出弁機構の開弁が行われるように構成したことを特徴とする請求項1に記載の燃料ポンプ。
- 空気排出口の径dがd≧0.3mmであることを特徴とする請求項1〜3のいずれか1項に記載の燃料ポンプ。
- 空気排出弁機構が開弁しているときに、空気排出口への空気の進入を防止する吸気防止弁機構を、上記空気排出弁機構に具備したことを特徴とする請求項1〜4のいずれか1項に記載の燃料ポンプ。
