Abstract

A solenoid valve, in particular for controlling a brake pressure of a wheel brake of a motor vehicle, includes a pole core, an axially moveably mounted armature, a valve element, a closure element, a plunger, and a pressure spring. One end of the armature is associated with the pole core. The valve sealing element is arranged at another end of the armature. The armature has an axial through-opening. The closure element is force-lockingly and/or interlockingly retained in the axial through-opening in a selectable position. The plunger is axially moveably mounted in the axial through-opening, which provides a connection to the pole core in an installation position. The pressure spring is positioned in the axial through-opening and is retained in a pretensioned manner between the plunger and the closure element. The closure element is designed as a three-dimensionally convex element.
