Fuel injector valve for combustion engines

The fuel injection valve has housing (1) in which a pressure space (5) is formed which is filled with fuel under high pressure. A nozzle needle (7) is arranged in the pressure chamber. The flow of fuel from the pressure chamber is controlled at an injection opening (10). A shift sleeve configured to interact with a sealing seat in the pressure chamber, so that lifting of shift sleeve by sealing seat between switching sleeve and sealing seat, a circuit is open to flow the fuel within the pressure chamber in flow direction of the injection opening.
