ABSTRACT:
An electromagnetically actuatable valve that serves in particular in inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing core with a surrounding magnetic coil and a guide diaphgram secured across the valve housing, the guide diaphragm urges an armature/valve closing element, embodied in one piece in the form of a spherical section, toward a valve seat. The guide diaphragm loosely engages a flat bearing face of the armature, so that the valve closing element can automatically center itself with respect to the valve seat. Upon a reciprocating movement of the armature/valve closing element, the frictional force between the guide diaphragm and the bearing face prevents a radial movement of the armature/valve closing element.
