摘要 <p>A hydraulic solenoid valve includes a valve housing with bores for receiving a hydraulic medium and having at least one consuming device connection and a return connection connected to the bores. A piston is connected within the valve housing and has at least one piston bore. A first valve with a corresponding valve seat is connected to the piston for opening and closing the piston bore. The first valve in its open position provides communication between the consuming device connection and the reservoir connection. A magnet housing has connected therein an armature. When the armature is displaced during normal operation in both directions, it rests at the first valve and forces the first valve into its valve seat. A return spring is positioned between the piston and the valve housing. The armature is displaceable by the force of the return spring. The piston is displaceable by the armature against the force of the return spring. The armature has at least one throttle passage on an end face facing away from the piston through which during displacement of the armature by the force of the return spring the hydraulic medium flows and generates a pressure counteracting the force of the return spring.</p>
