Abstract: A armature assembly for an electromagnetically actuatable 2/2 or 3/2 way valve with a tube-shaped armature outer part of a ferromagnetic material with a longitudinal axis and an armature inner part from a material with a lower density than the ferromagnetic material. The armature inner part being axially inserted in a mounting end of the armature outer part. Between the armature outer part) and the inserted armature inner part there is formed at least one axial through flow duct through the armature assembly, an axial hollow cylinder-shaped recess is formed for receiving a cylindrical spring; and a bottom) of the recess is formed by the armature inner part and/or the armature outer part as a support for an end of the spring.
