Solenoid valve having adjustable spring force

An armature assembly for a solenoid valve for controlling a brake pressure of a wheel brake of a motor vehicle, comprising:

• an armature with an axial passage;
• a valve sealing element arranged at an end of the armature;
• a closure element configured as a three-dimensionally convex body and retained in one of a plurality of selectable positions position in the axial passage by at least one of a force fit and/or a form fit;
• a plunger is axially moveably mounted in the axial passage and configured to provide a connection to a pole core in an installation position;
• and
• a compression spring positioned in the axial passage and held under preload between the plunger and the closure element.

A method for producing an armature for a solenoid valve, the method comprising:

• introducing a sleeve into an axial passage of the armature;
• introducing a plunger into the axial passage after introducing the sleeve;
• introducing a compression spring into the axial passage after introducing the plunger;
• inserting a closure element into the axial passage;
• fixing the closure element at a selected one of a plurality of selectable positions in the axial passage when the compression spring is preloaded between the closure element and the plunger and reaches a desired preload force;
• and
• applying a specific counter-force to the plunger in order to determine the preload force of the compression spring.
