AbstractAn 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. | InventorsAssigneeApplicationNo. 06/307241 filed on 09/30/1981US Classes:239/585.3, Plate-type armature valve (e.g., plate and integral projection or ball)239/900ELECTROMAGNETICALLY ACTUATED FUEL INJECTOR HAVING BALL AND SEAT TYPE VALVEField of Search239/285Flow controller and ground support interconnectionExaminersPrimary: Kashnikow, AndresAssistant: Sobel, Paul A.
