Abstract
An electromagnetically actuatable valve is proposed, which serves in particular as a fuel injection valve for fuel injection systems of internal combustion engines. The valve includes pole pieces supported in a valve housing, which are joined by a yoke on which a magnetic coil is disposed. Remote from the yoke, the first pole piece has a first pole and the second pole piece has a second pole, the pole pieces are arranged to extend toward one another and define therebetween a gap in which a nonmagnetic stop may be disposed. The pole pieces have a continuously extending, concave surface which confront a ball which serves as both the armature and the movable valve element. The ball is urged toward a valve seat by a guide diaphragm supportedly attached to the housing at its circumference.
