Abstract (en)
[origin: EP1865189A2] Fuel injector (10) comprises an actuator (70) arranged in the low pressure region (80) of the injector to directly operate a valve piston (94). Preferred Features: The valve piston has a first valve seat (104) and a second valve seat (106). The diameter of the second valve seat corresponds to the diameter of the piston guide (108). The actuator is connected either to the valve piston and a housing part (84) or by an actuator spring between them.
