Abstract

Device for injecting of fuel into internal combustion engines with an injection jet is provided with a stretched tension wire as a locking spring element for an outwardly opening valve locking member. The pretension of the tension wire is influenced by the current flow in an electrical current circuit which is fed to an electric resistor element being installed into the injection jet. The resistor element may be formed by the tension wire itself or by coil of an electromagnet, whose anchor is coupled with the tension wire. Thus, the opening pressure (P.sub.o) of the injection jet or the injection process can be controlled in a simple manner or may be formed accurately in accordance with a predetermined principle.
