Armature for electromechanical valve, valve having armature and method for producing armature

The invention relates to a novel armature assembly (100) for electromagnetically drivable 2/2 or 3/2 through valves, having a tubular armature outer part (110) made of a ferromagnetic material with a longitudinal axis (LA) and an armature inner part (120) made of a material having a lower density than the ferromagnetic material, which armature inner part is inserted axially at a mounting end (111) of the armature outer part (110), between the armature outer part (110) and the inserted armature inner part (120), at least one axial through-flow duct (130) is formed through the armature assembly (100), and an axial hollow cylindrical recess (140) is formed for accommodating the cylindrical spring (150); furthermore, a bottom portion (141) of the recessed portion (140) is formed by the armature inner portion (120) and/or the armature outer portion (110) as a support (160) for an end portion (151) of the spring (150). In addition, a manufacturing method for the novel armature assembly (100) is disclosed. Furthermo
