Abstract

A solenoid valve includes a magnet assembly, a valve cartridge having a pole core, a valve sleeve connected to the pole core, an armature, a valve body, and at least one spring tongue. The armature is guided in an axially movable manner within the valve sleeve and is coupled to a closing element. The magnet assembly generates a magnetic field via energization of a coil winding. The magnetic field is configured to move the armature counter to a force of a restoring spring. The valve body is positioned within the valve sleeve. A main valve seat of the valve body forms a main valve with the closing element that sets a fluid flow between at least one first fluid opening and at least one second fluid opening. The spring tongue is arranged on the valve sleeve and forms a positively locking connection between the valve sleeve and the valve body.
