Abstract
An electromagnetically actuatable valve that reduces the locking force of the valve has a seat valve, which can be transferred to a closing position counter to the force of a prestressed restoring spring. A valve seat communicates with an inflow side, and a closing member disposed on a tappet communicates on the outflow side of the valve. A magnet armature cooperates with the tappet in a valve dome which communicates with the outflow side. The magnet armature and the tappet are two separate components which positively support one another. On the inflow side, a longitudinal bore of the tappet originates at the closing member, and a first longitudinally movable pin is receive therein largely in a pressure-tight fashion. The cross section of the first pin is at least approximately equivalent to the sealing cross section of the valve seat. The longitudinal bore of the tappet is continued in the magnet armature. A second pin is received in that longitudinal bore. While the tappet and the magnet armature are pressure-equalized, in the closing position of the valve the inflow-side differential pressure is diverted, via the first and second pins nonpositively supported on one another, to an end wall of the valve dome. The valve can be used in hydraulic brake systems for motor vehicles.
