Abstract:
A valve device for a hydraulic circuit includes an actuator unit, a valve unit and an opening. The actuator unit comprises an electromagnetic circuit comprising a movable armature, a core, a coil configured to be supplied with a current and a flux guiding means, and a space arranged in a valve interior between the armature and the core. The valve unit comprises an outlet, an inlet arranged between the outlet and the space in the valve interior, a valve seat arranged between the inlet and the outlet, and a valve closing body connected with the armature. The valve closing body is spring-loaded towards the valve seat. The opening is arranged at an end of the valve unit opposite to the space. The opening comprises a valve tappet arranged therein. The valve tappet is pressure-loaded and displaceable counter to the valve closing body in an opening direction.
