Abstract (en)
[origin: EP2146085A1] The fuel injection valve device has a nozzle needle (3), which controls the opening of an injection opening (9) by its longitudinal movement. The fuel injection valve device has a control chamber (30), whose control chamber pressure works indirectly on the nozzle needle and a back and forth movable valve piston (20). The valve piston has two control pressure surfaces (26,43) in the direction of movement of the valve piston, which are charged with the control chamber pressure.
