Abstract

A magnetic valve that furnishes a large flow cross section and switches at high differential pressures. 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 first restoring spring. Guided on the armature is a valve closing member, movable longitudinally relative to the armature, of a seat valve. Also supported in the armature is a second restoring spring, which exerts a force acting in the direction of the pole core upon the valve closing member. The magnetic valve is especially suitable for slip-controlled hydraulic brake systems of motor vehicles.
