Abstract

A solenoid valve for controlling a fluid includes an armature having a base region, a lateral region and a head region. The solenoid valve includes a valve member connected to the armature. The solenoid valve further includes an armature casing component in which the armature is positioned. A flow path is formed between the armature and the armature casing component, the flow path extending from a lower armature space to an upper armature space and back to the lower armature space. A junction region is arranged between the head region and the lateral region. The junction region has at least one groove formed therein to facilitate an overflow between the lateral region and the head region.
