ABSTRACT:
A perfected fuel injector comprising a plunger for controlling fuel passage between an injection chamber and at least an injection orifice formed in an injection nozzel; 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 to a given value the pressure of the fuel inside the control chamber and so displace the plunger. 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 with a duct supplying fuel to the injection chamber and comprising an annular chamber and a radial hole formed in a sleeve housed in a hole on the body.
