Abstract (en)
A fuel injector (10) comprises an injector body (12), a nozzle body (16) and a retainer (42) for connecting the nozzle body (16) to the injector body (12). The nozzle body (16) comprises a fuel channel (22) extending from an upper contact surface (40) of the nozzle body (16) to at least one nozzle orifice (26). The injector body (12) comprises a low-pressure drain (36) and a fuel channel (20) extending from an upper part of the injector body (12) to a lower contact surface (38) of the injector body (12). The retainer (42) holds the lower contact surface (38) of the injector body (12) and the upper contact surface (40) of the nozzle body (16) in compressive butting relationship in such a way that the fuel channel (22) of the nozzle body (16) and the fuel channel (20) of the injector body (12) form a fuel delivery passage. An important feature of the fuel injector (10) is that at least one drain channel (44) extends from the retainer (42) to the low-pressure drain (36) arranged in the injector body (12). <IMAGE>
