Armature for an electro-mechanical valve, valve having the armature and manufacturing method for the armature

An armature assembly for an electromagnetically actuatable 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, said armature inner part being axially inserted in a mounting end of the armature outer part, wherein between the armature outer part and the armature inner part there is formed at least one through flow duct through the armature assembly, and a hollow cylinder-shaped recess is formed coaxially, wherein the recess is open at the end of the armature inner part opposite the mounting end for retaining a cylindrical spring and from the armature inner part and/or the armature outer part a bottom of the recess is formed as a support for an inner spring end of the spring.
