Abstract (en)
[origin: EP1559907A1] The fluid injector has a housing, an actuator unit and a valve body. The valve body has a cartridge (21) with a recess (211), that forms an injection nozzle (213), if it rests with its seat area on a needle seat of the cartridge. A further recess (217) or raised area in the cartridge (21), a holding element and a recess (226) or raised area in the needle (22) are formed and arranged in a way, that they cooperate to fix the needle (22) in its rotational position relative to the cartridge (21). <IMAGE>
