    摘要: 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.

    摘要: An electromagnetically operated valve, in particular a fuel injection valve for fuel injection systems, has a core surrounded by a magnet coil and an armature adjacent to the core for operating a valve closing body that interacts with a valve seat body. A reflux body surrounding the armature is magnetically isolated from the core by an isolation point. The core and/or the reflux body is made of a ferritic or ferromagnetic material whose permeability depends on the mechanical stress in the material. The core and/or the reflux body is mechanically deformed in a boundary area between the core and the reflux body to form the magnetic isolation point.
