ELECTROMAGNETICALLY CONTROLLED FUEL INJECTION VALVE

An electromagnetically actuatable valve is proposed which serves in particular to inject fuel into the intake tube of internal combustion engine operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell core having a magnetic coil and a flat armature, which is positively connected to a valve element comprising a ball which protrudes through a central opening in a guide diaphragm to cooperate with a fixed valve seat. The guide diaphragm guides the ball in the radial direction relative to the valve seat. Under spring tension, the flat armature, having a guide crown, contacts the guide diaphragm and is thus guided in a plane parallel to the end face of the shell core. A first fuel fitting comprises a portion of a valve housing preshaped by a non-cutting manufacturing method; a second fuel fitting is fixed inside the first fuel fitting in such a manner that a flow conduit is defined between the first and the second fuel fittings. The fuel flowing in via the second fuel fitting proceeds to the valve seat; when the valve is open, a portion of the fuel is delivered there to a nozzle bore in order to be metered. The non-metered fuel flows around the magnetic element and proceeds via the flow conduit into a fuel return flow line.
