    摘要: A fluid injection nozzle (5) is mounted on a fluid injector valve (1) in order to control the flow of (and atomize) fluid passing through an injection hole (3b) of the fluid injector (1). The fluid injection nozzle (5) may include at least one nozzle hole (5a) that comprises an inlet hole (51a), an intermediate hole (52a) and an outlet hole (53a). These holes preferably serve to impart a step-wise control of the fluid flow exhausted from the injection hole (3b). The intermediate hole (52a) may have a longitudinal axis (L2) that extends substantially perpendicular toward a nozzle axis (L1). The intermediate hole (52a) may include a first terminal end that communicates with the inlet hole (51a) and a second terminal end that communicates with the outlet hole (53a). The intermediate hole (52a) preferably has a substantially uniform width (W) along substantially the entire length in the longitudinal axis (L2). The outlet hole (53a) may have the central axis (L3) that is displaced from the longitudinal axis (L2) of the intermediate hole (52a) by a distance (Y).
