A solenoid valve (1) which is used in particular for systems on internal combustion engines comprises an external pole (2), an internal pole (3), a magnetic coil (20) and an armature (25). In this case, the internal pole (3) is connected to the external pole (2) via a body (33) and a non-magnetically conductive separating body (32). With the magnetic coil (20) being fed with current, a magnetic closure is produced which guides the body (33), the armature (25) and the external pole (2) via the internal pole (3). A formation of the magnetic closure is enabled by the magnetically conductive body (33), via which a strengthening of the magnetic attraction force (F) acting on the armature (25) is achieved with a given working air gap (s) between the internal pole (3) and the armature (25). |
