Abstract

A solenoid valve includes a housing within which is arranged a coil wound onto a coil former, an armature, a core, and a multiple-part return path arrangement, which together form an electromagnetic circuit. The armature is configured to be movable and to act at least indirectly on a valve closure element mounted in the coil former via a bearing. The multiple-part return-path arrangement comprises at least one return-path cover section, a return-path side section and a return-path inner section. The return-path inner section is arranged in the coil former.
