Description
前記蓋体には、その内部に保持されている前記レギュレータから流下した余剰燃料を前記ハウジング本体の内壁側まで送る余剰燃料排路が形成されているとともに、前記ハウジング本体には、前記余剰燃料排路末端側の下方位置で排出された余剰燃料を受ける上向きの燃料受け面が形成されており、前記余剰燃料排路を通って排出された余剰燃料を、前記燃料受け面でいったん受けてから前記ハウジング本体の内壁面を伝って前記燃料貯留槽に戻すことを特徴とする。
Claims (3)
- 燃料タンクからエンジンに至る燃料供給路の途中に配設され、リザーバタンクを兼ねる燃料貯留槽を形成したハウジング本体と該ハウジング本体の開口部を覆い気密する蓋体からなるハウジングの内部に、貯留した燃料を圧送する燃料ポンプと、圧送する燃料を所定圧力に調整しながら余剰燃料を前記燃料貯留槽に戻すレギュレータと、前記燃料貯留槽に貯留した燃料の油面を一定レベルに維持する燃料貯留量調整手段とを備えており、前記蓋体に設けた燃料吐出パイプから所定圧力の燃料を送出してエンジンに供給する燃料供給装置において、
前記蓋体には、その内部に保持されている前記レギュレータから流下した余剰燃料を前記ハウジング本体の内壁側まで送る余剰燃料排路が形成されているとともに、前記ハウジング本体には、前記余剰燃料排路末端側の下方位置で排出された余剰燃料を受ける上向きの燃料受け面が形成されており、前記余剰燃料排路を通って排出された余剰燃料を、前記燃料受け面でいったん受けてから前記ハウジング本体の内壁面を伝って前記燃料貯留槽に戻すことを特徴とする燃料供給装置。 - 前記余剰燃料排路が、前記蓋体の内部に保持された前記レギュレータのリターンポート下端側から前記ハウジング本体の内壁側に形成した前記燃料受け面の上方位置まで、余剰燃料が重力の作用で移動するように形成されていることを特徴とする請求項1に記載した燃料供給装置。
- 前記余剰燃料排路が、余剰燃料の吐出口がある前記リターンポート下端側から下向きに延びた縦通路を有しており、該縦通路は、下端部が上向きの当たり面で閉止されているとともに下端側の内周面の一部を側方に開口してなる排出口が形成されており、前記当たり面で流下した余剰燃料を受け止めてから前記排出口を介して前記燃料受け面の上方に排出することを特徴とする請求項2に記載した燃料供給装置。
