Abstract (en)
[origin: WO2012058703A1] The invention relates to a device for injecting fuel into the combustion chamber of an internal combustion engine with at least one injector (1) comprising an injector body that is equipped with a high-pressure accumulator (6), a nozzle needle (15) which is guided in the injector (1) in an axially movable manner and which is surrounded by a nozzle chamber (19), a high-pressure line (8) that connects the high-pressure accumulator (6) to the nozzle chamber (19), and a resonator line (20) which is connected parallel to the high-pressure line (8) and which is connected to the nozzle chamber (19) and opens into the high-pressure accumulator (6) via a resonator throttle (21). The resonator line (20) and the high-pressure line (8) are formed in a retaining body (5) at least in the line section adjoining the high-pressure accumulator (6), said retaining body being screwed into the accumulator pipe (22) that forms the high-pressure accumulator (6) at the retaining body end face.
