ABSTRACT:
An accumulator fuel injection apparatus in which a nozzle element is divided into a first nozzle having one end side of said nozzle element and a second nozzle having the other end side of the nozzle element. The accumulator fuel injection apparatus comprises a stopper for setting a maximum movement position of the first nozzle toward the second nozzle, a second pressure control chamber communicating with a first pressure control chamber and forming a predetermined space or interval through which the first nozzle and the second nozzle are spaced away from each other under a condition that the first nozzle is arranged at the maximum movement position, and delay apparatus for delaying reduction of pressure within the first pressure control chamber due to the fact that fluid flows into a low-pressure chamber from the first pressure control chamber upon communication of the first pressure control chamber and the low-pressure chamber with each other. It is possible to easily perform operation of setting an amount of pre-lift of the nozzle needle which decides an injection rate, and operation of assembling constitutional elements thereof.
