Abstract (en)
[origin: EP1541859A1] The injection valve has a nozzle module (3) with a first nozzle needle (4) interacting with a first injection orifice (7), and a second nozzle needle (5) interacting with a second injection orifice (8) and axially movable inside the first nozzle needle. A control module with a control chamber (9) controls the fluid pressure. The first nozzle needle has at least one driver (18) which effects an opening and closing of the second nozzle needle and is formed by a control piston of the first nozzle needle and which preferably encompasses a section of the second nozzle needle with reduced diameter.
