Abstract: A solenoid valve includes a valve sleeve comprising a valve seat, a valve closure element which acts on the valve seat, and a housing. Arranged in the housing is a coil, an armature, a core, and a multiple-part return-path arrangement, which form an electromagnetic circuit. The core is arranged on a side of the housing opposite to the valve sleeve and is wound onto a coil former. The coil former comprises a first portion with an internal diameter and a receiving bushing for the valve sleeve arranged on a side opposite to the core. A movable armature acts on the valve closure element. The armature is mounted in the coil former via a bearing and comprises parts including a first part directed toward the core having a diameter. The diameter of the first part is larger than the internal diameter of the first portion of the coil former.
