Abstract
The fuel injection valve is provided with a pair of ceramic rings in order to define a plurality of nozzles for injecting fuel into a combustion chamber. The two rings are mounted about an annular groove on an end of the valve body and communicate with a fuel delivery duct. The rings are mounted in place by threaded rings and intermediate rings with conical surfaces facing a conical surface of the valve body.
