Abstract
An electromagnetically actuatable valve is proposed that serves in particular as a fuel injection valve for fuel injection systems of internal combustion engines. An armature cooperates with magnet poles, and a bearing cone the length of the generatrix of which is approximately equivalent to the diameter is machined into a valve seat body. The armature and valve seat body may also have bearing faces of calotte shape facing one another.
