Abstract:
The invention relates to an injection nozzle for an internal combustion engine having a nozzle needle or needle unit for controlling an injection of fuel through at least one injection orifice and an actuator for driving a coupling piston. The nozzle needle or needle unit has a control surface that at least partially delimits a control chamber which communicates with a coupling chamber that is at least partially delimited by the coupling piston. The control surface is situated at the end of the nozzle needle or nozzle unit oriented away from the at least one injection orifice and the actuator drives the coupling piston to open the nozzle needle in such a way that a volume of the coupling chamber increases.
