燃料噴射弁。[Claims for Utility Model Registration] 1. A nozzle body having a hole for injecting fuel, a valve body that is loosely inserted into the nozzle body and works together, and a driving means for driving the valve body, which are arranged in a casing. The fuel injection means is integrally housed in the nozzle body, and the atomization means has an atomization element disposed facing the injection port with a slight distance therebetween and supported in a holding cylinder through an elastic body. 1. A fuel injection valve, which is fixed to the outer periphery, and the atomizing element is an annular piezoelectric element which is driven by ultrasonic waves and whose outer surface is coated with insulation. 2. Utility model registration claim 1, characterized in that the ultrasonic frequency in ultrasonic driving is the resonant frequency of a resonant system consisting of the support spring constant of the elastic body and the mass of the piezoelectric element to be ultrasonically driven. Fuel injection valve as described.
