ABSTRACT:
An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection. The fuel injection valve includes a valve housing, a shell core with a magnetic winding, and a flat armature which is firmly connected to a valve element having a tubular section and a spherical section. A guide diaphragm attached to the housing engages a guide edge of the flat armature in an elastic manner and guides the flat armature parallel to the end face of the shell core. The coaxial guidance of the spherical section relative to the valve seat is effected by means of guide faces of a guide ring. As a result, the movable valve element can have an elongated embodiment, and the fuel injection can be effected at any desired location of the intake tube, while the valve simultaneously requires little installation space.
