Patent ID: 7878427

Claim:
An injector for fuel injection in an internal combustion engine, the injector having an injector body, a fuel line connected to the injector body, the fuel line having an end, and through which fuel line fuel at high pressure is delivered, a filter bore in the injector body, the filter bore having a longitudinal axis and a fuel filter disposed in the filter bore through which the delivered fuel flows, and a sealing seat formed in the filter bore against which the end of the fuel line is pressed upon fastening of the fuel line to the injector body, the improvement wherein the filter bore extends to the outside edge of the injector body; wherein the sealing seat has a longitudinal axis and is disposed with its longitudinal axis inclined to the longitudinal axis of the filter bore; wherein a further bore is formed in the injector body, which further bore extends at least approximately coaxially with the longitudinal axis of the sealing seat and into which the end of the fuel line plunges; wherein, the end of the fuel line plunges into the further bore and engages against the sealing seat, thus dividing the filter bore into an outer end region which extends to the outside edge of the injector body, and an inner end region of the filter bore; and wherein the fuel filter is disposed in the inner end region of the filter bore.
