ABSTRACT:
A valve seat portion has fuel flow passages arranged between guide portions at predetermined intervals along an outer circumference of a valve body. In addition, a fuel jet adjusting plate has nozzle holes arranged along a circle coaxial with the outer circumference of the valve body, the nozzle holes corresponding to the guide portions. Therefore, even if the valve body rotates circumferentially relative to the valve seat portion, no alteration in the pressure applied to fuel flowing through the nozzle holes occurs. By suitably setting relative locations between the respective nozzle holes and the guide portions and the numbers thereof, the pressure applied to fuel injected from the respective nozzle holes is adjusted, whereby the fuel injected from the respective nozzle holes is optimally atomized.
