Abstract
The invention concerns an injector for the injection of fuel into the combustion chambers of combustion engines. Inside an injector housing (9) is located a nozzle needle (14), which is surrounded by a nozzle chamber (18). The nozzle needle (14) is moveable back and forth within the injector housing, and is aligned by the guiding sections (16, 22) inside the injector housing (9). A thick spring (11) pressed the nozzle needle against the injector (14) a ring canal (23) is formed between injector housing (9) and nozzle needle (14) and a conical section (33) of said nozzle needle (14) follows in the direction towards the seat (30).
