Abstract (en)
[origin: WO2016096217A1] The invention relates to an injection nozzle (1) for fuels, comprising a nozzle body (2), in which a pressure chamber (4) that can be filled with fuel under high pressure is formed, in which pressure chamber a piston-shaped nozzle needle (3) is arranged in such a way that the nozzle needle can be moved longitudinally. A sealing surface (6) is formed at one end of the nozzle needle (3) and an end face (9) is formed at the opposite end, wherein the sealing surface (6) interacts with a nozzle seat (5) in order to open and close at least one injection opening (8). A control chamber (10) that can be filled with fuel under changing pressure is bounded by the end face (9) of the nozzle needle (3) such that a force can be applied to the end face (9) in the direction of the nozzle seat (5) by means of the hydraulic pressure. The nozzle needle (3) has an elastic longitudinal segment (25), which has a longitudinal stiffness of less than 40,000 N/mm.
