Abstract (en)

[origin: EP0961024A1] The fuel injector (1) for a diesel motor, has a jet body (2) and a bonded jet head (3) and at least one jet opening (31) for the fuel to be delivered to a combustion zone. An initial pressure zone (6) is within the jet body (2) with a fuel feed line (12) opening into it. At least one connecting line (13) links teh pressure zone (6) and jet opening (31) to carry fuel from the pressure zone (6) to the jet opening (31). A jet needle (7) within the jet body (2) works with a valve seat (8) to open and close the link between the pressure zone (6) and the connecting line (13). A second pressure zone (9) is between the first pressure zone (6) and the jet opening (31). A second needle (10) works with a second valve seat (11) to open and close the connection between the second pressure zone (9) and the jet opening (31).
