Abstract (en)

[origin: WO2006034890A1] The injector comprises an injector body (28) whereon a fuel line (18) is connected and through which highly pressurised fuel is guided. A filter bore (60) is provided in the injector body (28) wherein a fuel filter (64) is arranged and through which the guided fuel flows. A sealing seat (66) is formed in the filter bore (60) which is pressed counter to the end (70) of the fuel line (18) during fixing thereof onto the injector body (28). The filter bore (60) leads to the external side of the injector body (28).The sealing seat (66) is arranged with the longitudinal axis thereof (67) in an inclined manner on the longitudinal axis (61) of the filter bore (60) and a bore (68) extending at least approximately coaxial to the sealing seat (66) is arranged in the injector body (28) wherein the end region of the fuel line (18) emerges.An end region of the fuel line (18) introduced into the bore (68) separates an end region (63) of the filter bore (60) which leads to the outer side of the injector body (28) of an end area (62) of the filter bore (60) which is impinged upon by high pressure. The fuel filter (64) is arranged in the inner end region (62) of the filter bore (60).
