Abstract
本発明の燃料噴射装置は、プランジャ(110)を摺動自在に収容して燃料の圧送室(C)を画定する筒体(140)、圧送室に連通し得る供給口(161a)をもつ燃料の供給通路(221a)、供給通路内の燃料が圧送室へ流入するのを許容する第1弁体(160)、燃料の一部を元に戻し得る戻し通路(136)、供給通路と戻し通路を連通する連通路(147)、圧送室内の燃料を戻し通路に排出する排出口(141b)をもつ排出通路(146)、圧送室内の加圧された燃料を噴射する噴射ノズル(300)を備え、排出通路(146)は、供給口(161a)及び排出口(141b)よりも上方の所定位置まで延在する隔壁(148)により連通路(147)から隔離されて、戻し通路(136)に連通するように形成されている。これによれば、圧送室内の燃料に混入したベーパが効率良く排出され、特に高温時において安定した高精度の燃料噴射を行うことができる。
