Disclosed is an injector for fuel injection, with a magnet valve for controlling an injection valve, in which the magnet valve has a movable armature that can be moved onto a valve seat in the lower armature chamber. The lower armature chamber communicates fluidically with the control pressure chamber of the injection valve via bores. Via a return bore, incidental leak fuel quantities can be returned to a tank via the lower armature chamber. To prevent armature recoil upon closure of the valve seat by the armature, it is proposed that means be provided in the injector for reducing pressure fluctuations occurring in the lower armature chamber. Eliminating pressure fluctuations in the lower armature chamber leads to maximal elimination of armature recoil.
In an injector for fuel injection, with a magnet valve (1) for controlling an injection valve (2), in which the magnet valve (1) has a movable armature (3) that can be moved onto a valve seat (4) in the lower armature chamber (5), which chamber in turn is in fluid communication, via one or more bores (6, 7), with the control pressure chamber (8) of the injection valve (2), and in which a return bore (9), leading to the lower armature chamber (5), is provided in the injector for returning leak fuel quantities to the lower armature chamber (5), the improvement comprising
