Abstract (en)
[origin: EP0864743A2] The fuel injection valve has in a valve body (1) an axially sliding valve member (5) which has a sealing face (7) at one end. With this face it works together with a valve seating face (9) on the valve body to control an injection cross-section. From the seating face, at least one injection opening leads into the combustion chamber. There is an electrical control member (23) operating the valve member axially through a hydraulic working chamber (19). A second electrical control member (27) is provided to operate the valve member, controlled independently of the first one. The hydraulic working chamber is bounded by a valve piston (17) connected to the valve member and by adjusting pistons (25,29) connected to the control members.
