ABSTRACT:
A fluid injection valve includes a valve seat having a conical concave surface and a valve seat surface, a needle having an edge surface and an annular contact surface whose diameter is Ds, an orifice plate having a perforated surface disposed in a downstream portion at a distance h from the edge surface of the needle and at a distance H from valve seat surface. Thus, a fluid chamber is defined by the perforated surface of the orifice plate, the edge surface of the needle and the conical concave surface of the valve seat. The perforated surface has a plurality of first orifices having a diameter d on a first circle whose diameter is DH. The fluid chamber is formed to have the following relationships among the diameters Ds, DH, d and the distances h, H: 1.5<Ds/DH<6, h<1.5 d, and H<4 d.
