Abstract:
1. A solenoid valve with an electromagnetic circuit, the solenoid valve comprising: a return plate; a yoke; a coil wound onto a coil carrier, the coil carrier comprising an internal thread; a two part core comprising an inner core member with an external thread and an outer core member with both an internal thread and an outer thread, the internal thread of the outer core member being configured to cooperate with the outer thread of the inner core member, the two part core being disposed in the coil carrier so that a direct interlocking connection exists between the outer thread of the two part core and the internal thread of the coil carrier, the outer thread of the two part core being disposed within the internal thread of the coil carrier and configured to provide an adjustment for the two part core; and an armature configured to be movable and to act at least indirectly on a valve-closing element, the armature being directly supported by the coil carrier, wherein, an adjustment of the two part core changes a magnetic characteristic of electromagnetic field lines through the armature, the two part core, the return plate, and the yoke, so as to thereby adjust a force acting on the armature.
