Abstract: A fuel injection device for internal combustion engines, in which the control of the high-pressure delivery of the pump piston is achieved via a magnet valve disposed in a line between the pump work chamber and a fuel tank. To that end, the magnet valve has a valve member, actuated counter to the force of a valve spring by an electrical actuator and the valve member cooperates, by its sealing face with a valve seat and is pressure balanced via a cross-sectional constriction, which is disposed in a pressure chamber that communicates with the pump work chamber. In the event of a fracture of the valve member, in order to avoid blocking of the magnet valve when closed and an attendant uncontrolled, excessive fuel injection quantity, an axial bore is disposed inside the valve member, which bore feeds into a connecting line and on into the low-pressure chamber, and via which the high fuel pressure can drop after the valve member breaks.
