In an apparatus for injecting fuel into the combustion chamber of an internal combustion engine, including an injection nozzle (5) having an axially displaceable nozzle needle (17) to which the pressure present in a control chamber (13) filled with fuel can be applied in the axial direction to control the opening and closing movements of said needle, wherein the pressure in the control chamber (13) is controlled via a solenoid valve (7) opening or closing at least one inlet or outlet duct (14) for fuel and in which a magnetic coil (28) cooperates with an armature (27) and a valve-closing member that can be pressed against a valve seat (15) is coupled to the armature (27), said armature (27) being disposed in an armature chamber (19) into which the inlet or outlet duct (14) opens, the magnetic coil (28) is covered by a metal protective plate (30) on the side of the armature chamber. |
