Abstract
The invention relates to an injector for injecting fuel into the combustion chambers of an internal combustion engine, where the fuel compressed in a compression unit can be supplied via a pressure line to a nozzle chamber, which encompasses a nozzle needle of the injector. This nozzle chamber communicates with the injection nozzle protruding into the combustion chamber of the internal combustion engine, where the injector contains a fluid control unit. The fluid control unit is embodied as a hydraulic module, which is replaceably disposed in the housing of the injector and can either be actuated by an actuator or can be electromagnetically actuated.
Claims10
An injector for injecting fuel into a combustion chamber of an internal combustion engine, the injector comprising
- a compression unit (7) for compressing fuel to be supplied via a pressure line (5) to the nozzle chamber (4), which encompasses a nozzle needle (3) of the injector and communicates with the injection nozzle (6) protruding into the combustion chambers of the internal combustion engine, and
- the injector (1) containing a fluid control unit, embodied as a hydraulic module (14, 31, 36, 42), which is replaceably disposed in the housing (2) of the injector (1), the hydraulic module being actuated either by an actuator or electromagnetically actuated.
