Abstract
The invention relates to a solenoid valve, in particular for a brake system of a motor vehicle, having 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 having a compression spring acting in prestressed fashion between the pole core and the armature. It is provided that the compression spring is held in prestressed fashion in an axial passage of the armature, between a bolt, having the valve sealing body and held in a selectable position in the axial passage in force- and/or form-locking fashion, and a thrust piece, disposed such that it can be pushed out of the axial passage up to a stop and subjects the pole core to the prestressing force. The invention further relates to an armature for a solenoid valve. Finally, the invention relates to a method for producing an armature for a solenoid valve.
