Solenoid valve, armature for a solenoid valve, and method for producing an armature for a solenoid valve

A solenoid valve, in particular for a brake system of a motor vehicle, comprising:

• an axially displaceably supported armature, on one end of which a valve sealing body is disposed and with the other end of which a pole core is associated;
• and
• a compression spring acting in prestressed fashion between the pole core and the armature, wherein the compression spring is held in prestressed fashion in an axial passage of the armature, between a bolt, having the valve sealing body and being held in a selectable position in the axial passage in force- and/or form-locking fashion, and a thrust piece, disposed such that the thrust piece can be pushed out of the axial passage up to a stop, the thrust piece subjecting the pole core to a prestressing force of the compression spring. wherein the bolt is press-fitted into the axial passage and wherein the bolt and/or the thrust piece each have at least one longitudinal slot on an outer jacket face thereof.
