ABSTRACT:
A fuel injection valve for an internal combustion engine includes a fuel storage compartment and a pressure chamber from which a reciprocating pump piston delivers fuel to the engine's fuel lines. The fuel conduit between the storage compartment and the pressure chamber can be closed off by an electromagnetic valve. To permit engine operation even when the electrical system is non-functional, the magnetic valve is of the normally open type, held open by a spring. In the energized state, the valve closes off the fuel conduit and its closure is aided by the fuel pressure gradient across the valve.
