ンジャ２を往復動させることによって燃料を圧送可能と
する一方、該プランジャ挿入穴９の中段部に燃料室２０
を形成して該燃料室２０内に燃料通路２７を介して燃料
を供給し得る如くするとともに、該燃料室２０内におい
て前記プランジャ２の外側に摺動且つ回動自在に環状弁
３を嵌装し、さらに機関の回転状態に応じて前記プラン
ジャ２と前記環状弁３とを適宜に相対回動させることに
より前記環状弁３が前記プランジャ２の頂部２ａと側周
面２ｂ間にまたがって形成された通油孔２２を開閉する
時期を変化させるようにしもって燃料の噴射量を制御し
得る如くするとともに、前記環状弁３を前記プランジャ
２の軸方向に変位せしめることによって燃料の噴射時廟
を制御し得る如くした燃料噴射ポンプであって、前記燃
料通路２７を前記燃料室２０の上部から上向傾斜させて
形成したことを特徴とする燃料噴射ポンプ。Fuel can be pumped by reciprocating the plunger 2 within the plunger insertion hole 9 formed in the pump body 1, while a fuel chamber 20 is provided in the middle part of the plunger insertion hole 9.
is formed so that fuel can be supplied into the fuel chamber 20 through a fuel passage 27, and an annular valve 3 is slidably and rotatably fitted outside the plunger 2 within the fuel chamber 20. Further, by appropriately rotating the plunger 2 and the annular valve 3 relative to each other according to the rotational state of the engine, the annular valve 3 is formed to straddle between the top portion 2a and the side circumferential surface 2b of the plunger 2. The fuel injection amount can be controlled by changing the timing of opening and closing of the oil passage hole 22, and the fuel injection timing can be controlled by displacing the annular valve 3 in the axial direction of the plunger 2. A fuel injection pump characterized in that the fuel passage 27 is formed to be inclined upward from the upper part of the fuel chamber 20.
