Abstract:
A fuel injection valve includes a nozzle body and a plate. The nozzle body includes an injection orifice, through which fuel is injected, a needle that controls the injection through the injection orifice, and a needle-receiving bore that receives the needle. The plate is adjacently provided to the nozzle body for defining a fuel passage therein, through which fuel is supplied to the needle-receiving bore. The plate has an annular groove, which connects the fuel passage with the needle-receiving bore, at an end surface of the plate toward the nozzle body.
