Title: FUEL INJECTION VALVE FOR INJECTING A GASEOUS AND/OR LIQUID FUEL
Abstract:
The invention relates to a fuel injection valve for injecting a gaseous and/or liquid fuel into a combustion chamber of an internal combustion engine, comprising a first valve element (3) accommodated in a central bore (1) of a nozzle body (2) such that the first valve element can move to and fro, and a second valve element (5) accommodated in a central bore (4) of the first valve element (3) such that the second valve can move to and fro, wherein each valve element (3, 5) is assigned a control chamber (6, 7), which can be loaded with liquid fuel via an inlet throttle (8, 9) and unloaded via a valve (10). According to the invention, the valves (10, 11) are connected one after another and only one actuator (12) is provided to actuate the valves (10, 11).
