Abstract (en)
[origin: EP1088985A2] The injector has an injector body (20) with injector body section (30) and a nozzle body section (40) with an axial bore (50). A fuel delivery bore (60) in the injector body opens into the axial bore. A control piston (70) moves within the axial bore below a control chamber (100) with a relief valve (90). A nozzle needle (80) connected to the piston extends through the axial bore to open and close an injection opening (290). A nozzle spring (160) biases the needle in a seat (170) near the injection opening. The fuel delivery bore opens into a region beneath the control piston in the axial bore and the delivery of fuel to the control chamber from the region of the bore beneath the control piston takes place via a bore (110) in the control piston.
