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.

[ What is claimed and desired to be secured by Letters Patent of the United States is:] [1.] A magnetic control valve (10), for disposition in an intake brake line (14), said control valve extends between a master cylinder (11) and an intake side of a pump (13), of a slip-controlled hydraulic brake system for motor vehicles, comprising:an armature (23) that is longitudinally movable by an electromagnet (17) counter to a force of a first restoring spring (22) having one end that engages one end of a pole core (20), and another end that engages the armature (23);a valve closing member (36) that is longitudinally movable relative to the armature (23) and cooperates with a stationary valve seat (37) of a seat valve (35) is guided on the armature (23), remote from the pole core;the valve closing member (36) is located in a chamber (26) that communicates with an inflow side (29) of the magnetic valve (10);a second restoring spring (38) is secured to the armature on a face end of the armature (23) remote from the pole core and exerts a force acting in a direction of the pole core (20) upon the valve closing member (36);the valve closing member (36) is lifted from the valve seat (37) by the armature (23) with reinforcement from the second restoring spring (38) when the electromagnet (17) is excited; andthe second restoring spring (38) is a washerlike spring.
