Abstract

An electromagnetically actuated valve, includes an axially movable valve needle that includes at least one armature and one spherical valve-closure member. The armature forms a closing-member support, which receives the valve-closure member in a downstream end area. In this context, the end area encompasses the valve-closure member such that at least one channel, in direct connection with a longitudinal bore of the armature, is formed on the surface of the valve-closure member. The valve is well suited for use in fuel injection systems of mixture-compressing internal combustion engines having externally supplied ignition.
