ABSTRACT:
A magnetic valve that switches at high differential pressures and furnishes a large flow cross section. The magnetic valve has an armature, which when current is supplied to a coil is movable toward a pole core counter to the force of a restoring spring. The armature is capable of opening an auxiliary valve of small sealing diameter directly and a main valve of large sealing diameter indirectly. The auxiliary valve and the main valve have a common closing body, which is movable relative to the armature with a limited stroke. The auxiliary valve communicates through a conduit of the closing body with the outflow side of the magnetic valve. In the open position of the magnetic valve, the closing body is held by a stop ring of the armature. The magnetic valve is suitable in particular for slip-controlled hydraulic brake systems of motor vehicles.
