Abstract
A device for injecting fuel into the combustion chamber of an internal combustion engine with at least one injector includes an injector body equipped with a high-pressure accumulator, a nozzle needle axially displaceably guided in the injector and surrounded by a nozzle chamber, a high-pressure line connecting the high-pressure accumulator to the nozzle chamber, and a resonator line arranged in parallel with the high-pressure line and communicating with the nozzle chamber and opening into the high-pressure accumulator via a resonator throttle. The resonator line and the high-pressure line, at least in their sections adjacent the high-pressure accumulator, are formed in a retaining body which, on its end face, is screwed into the accumulator pipe forming the high-pressure accumulator.
