Abstract
A fuel injector is provided wherein an accumulating chamber is formed around a needle valve in a nozzle assembly housing to open and close an inlet port. An injection end control valve is disposed between the accumulating chamber and a fuel passage having communication with an atmospheric pressure side of the needle valve. The injection end control valve functions to introduce high-pressure fuel from the accumulating chamber into the atmospheric pressure side of the needle valve. Thus, rapid closing of the needle valve is enabled.
