A fuel injector (10) for internal combustion engines, comprising an external casing (11) provided with at least an inlet (13) and at least an outlet (14) for the fuel to be injected, an obturator element (16), means (18) for moving the obturator element (16) between a closed position, in which it closes the communication between the inlet (13) and the outlet (14), and an open position, in which it opens the communication between the inlet (13) and the outlet (14), a fixed endrun element (21) designed to come into contact with the obturator element (16) in order to halt said obturator (16) in the open position and an elastomer ring (30) interposed between the obturator element (16) and the endrun element (21), the elastomer ring (30) exhibiting a transversal generating section (300) comprising at least a portion (301) having an inclined development with respect to a central axis (X) of the elastomer ring (30). |
