ABSTRACT:
A fuel injector equipped with an injection valve comprising a mobile plunger ending with a sealing head; a support body having a tubular shape and comprising a feed channel; and a sealing body, in which is defined a valve seat of the injection valve; the sealing head is of a frustoconical shape, is arranged externally relative to the guide element, is thrust by a spring against said guide element in a direction contrary to the direction of feed of the fuel; the valve seat has a frustoconical shape which is a negative reproduction of the frustoconical shape of the sealing head in order to impart an internally hollow conical shape to the injected fuel.
