An injector comprising a plunger for controlling fuel passage between an injection chamber and at least an injection orifice formed in an injection nozzle; and an electromagnetic fuel metering valve for controlling fuel passage through a drain orifice between a control chamber, supplied with fuel under pressure, and a low-pressure chamber, so as to reduce the fuel pressure in the control chamber to a given value and so displace the plunger; characterised by the fact that pressurized fuel is supplied to the injection chamber and control chamber by means of a single fitting connected to a supply pipe and coming out inside a supply orifice formed in the injector body and communicating with the control chamber and a duct for supplying fuel to the injection chamber.
