Abstract
A fuel jet adjusting plate has first nozzle holes arranged along a first circle coaxial with a central axis of a valve body and second nozzle holes arranged along a second circle coaxial with the central axis and having a diameter larger that the first circle. The second nozzle holes have an opening area smaller than that of the first nozzle holes. Thus, despite the fact that fuel flows at a lower rate upstream of inlet portions of the second nozzle holes than upstream of inlet portions of the first nozzle holes, it is possible to suitably atomize both the fuel spray injected through the first nozzle holes and the fuel spray injected through the second nozzle holes
