Abstract

The invention relates to a fuel injection valve (1), particularly suitable as injector for fuel injection units on a force-fed, spontaneous ignition internal combustion engine, comprising an actuator (17) arranged in a valve housing (2) and a valve sealing body (5) operated by the actuator (17) by means of a valve needle (6), which cooperates with a valve seat surface (4) to give a sealing seat. The actuator (17) comprises several electrodes (42, 43) and at least one internal recess (40, 41) in which an electrical line (26, 27) is at least partly inserted. A contact means (44, 47) is provided in the recess (40, 41), connected to a part of the electrodes (42, 43), whereby the electrical line (26, 27) is at least indirectly connected to the contacting means (44, 47).
