摘要

The hydraulic directional control valve has an electromagnet (2) as actuating element for a control slide (5) with a control edge (12). A hollow valve sleeve (4) is arranged axially movable within a cylindrical shape. The valve sleeve has a radial valve casing borehole (13), which is arranged with the area of the control edge. A restring spring presses the control slide on the front side. The control slide is designed in such a manner. The control edge of the chamber located before the front side of the control slide limits the restring spring for valve sleeve.
