Abstract
A valve cartridge for a magnet valve has a capsule, an armature movable within the capsule, a valve insert, and a valve body. One end of the valve insert inserted into the capsule, and a valve seat of the valve body inserted into a second end of the valve insert. The armature moves a plunger within the valve insert. The plunger has a base body and a closing body. A closing element of the closing body sealingly plunges into the valve seat. The base body includes an equalization groove, which enables volume equalization between a sealing region and an armature chamber. The plunger has a closed cylindrical outer contour on the end thereof facing the armature, which forms a radial guide of the plunger in the valve insert, and an axial recess, which overlaps with the equalization groove and is connected to the armature chamber via a radial recess.
