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 than that of the first circle. Each hole axis of the second nozzle holes forms an acute angle with a reference plane perpendicular to the central axis of the valve body smaller than that formed by each hole axis of the first nozzle holes with the reference plane. Hence, fuel sprays injected through the first nozzle holes can be directed away from fuel sprays injected through the second nozzle holes. As a result, the fuel sprays injected through the first nozzle holes do not interfere with the fuel sprays injected through the second nozzle holes, which makes it possible to suitably atomize injected fuel.
