- 燃料噴射を制御する燃料噴射システム内の装置(4)であって、
作動中に噴射される燃料が流れる空間(6)を内部に有する本体部(5)と、前記空間内に開口する燃料入口開口部(7)及び出口開口部(8)と、前記空間内に移動可能に配置され、前記燃料入口開口部(7)と前記出口開口部(8)との間に流れ連結を生じるように配置された経路等(12、14、15)を有するピストン手段(9)とを備え、前記ピストン手段(9)は、前記空間(6)を、前記入口開口部(7)に連結される第1の部分(6.1)と、前記出口開口部(8)に連結される第2の部分(6.2)とに分割することができ、また、前記ピストン手段(9)に対して燃料流の主な方向と反対方向へ作用する力を生じるばねなど(10)を備えている装置において、前記ピストン手段(9)及び前記本体部(5)は、前記ピストン手段が前記入口開口部(7)に隣接するかそれに近い端部にあるときに、前記空間の少なくとも1つの第3の部分(6.3)を形成し、
前記第3の部分の容積は前記ピストン手段(9)及び本体部(5)の相互位置に依存していて、前記ピストン手段(9)が前記入口開口部(7)に隣接する端部にあるときに前記第3の部分(6.3)の容積が最小であり、前記ピストン手段が前記入口開口部(7)に隣接する端部から離れてある距離(L1)だけ後退すると前記第3の部分(6.3)の容積が増加し、前記ピストン手段(9)が前記ある距離(L1)を越えて後退すると前記空間の前記第3の部分(6.3)及び前記第1の部分(6.1)が併合されるようになっており、また、
前記第3の部分(6.3)は、前記燃料入口開口部(7)及び/又は前記第1の部分(6.1)と絞り経路(13)を介して連続的に流れ連結されていることを特徴とする装置。 - 前記ピストン手段(9)及び前記空間(6)は円筒形に形成され、それらが前記ピストン手段及び前記空間の中心軸線から異なる距離に形成された少なくとも2つの別個の摺動表面(17、17’、18)を形成することを特徴とする、請求項1に記載の配置。
- 前記空間(6)は、円筒形であって、異なる直径(CD1、CD2)を有する少なくとも2つの部分(5.1、5.2)を備えていて、小さい方の直径(CD1)を有する部分(5.1)は前記入口開口部(7)に隣接する端部にあり、前記ピストン手段(9)はそれに応じて異なる直径(PD1、PD2)を有する2つの部分(9.1、9.2)を備えていて、小さい方の直径(PD1)を有する部分(9.1)は前記入口開口部(7)に隣接する端部にあり、また、小さい方の直径を有する前記ピストン手段の前記部分(9.1)の長さ(L2)及び小さい方の直径を有する前記空間(6)の前記部分(5.1)の長さ(L1)は両方とも、前記ピストン手段(9)のストロークの長さ(L3)よりも短いことを特徴とする、請求項1に記載の配置。
- 前記ピストンが前記出口開口部(8)に隣接する端部にあるときに、前記ピストン手段は前記本体部(5)と結合し、それによってそれらが前記入口開口部(7)への燃料の流れ連結を閉鎖することを特徴とする、前述の請求項の何れか1項に記載の配置。
