Abstract (en)
[origin: US4416423A] An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell-type core having a magnetic coil, and a flat armature. The flat armature is firmly connected with a spherical valve element which passes through a central guide opening in a guide diaphragm and cooperates with a fixed valve seat. The guide diaphragm guides the valve element in the radial direction toward the valve seat. The flat armature contacts the guide diaphragm via a concentric shoulder providing tension thereto so that the armature is guided in a plane parallel to the end face of the shell core. The fuel supply to the valve is effected via radial inlet openings in the valve wall. The non-metered fuel, after flowing through the magnetic element, can flow into a fuel return flow line by way of radial outlet openings which are axially offset and sealed from the inlet openings.
