Actuators for hydraulic valve

An actuator for a hydraulic stroke or pressure control valve for a motor vehicle, the actuator comprising:

• a magnetisable actuator housing that envelops a magnet coil;
• a pole group arranged in a receiving opening of the actuator housing,
• wherein the pole group includes a pole core and a pole tube,
• wherein an axially movable armature is arranged in an inner cavity of the pole group,
• wherein the armature is configured to axially move a piston of the hydraulic valve by a pin that is supported axially movable in the pole group,
• wherein the actuator is configured to perform an anti-stick function and a contact damping function,
• wherein the pin directly contacts a first armature face of the armature that is oriented towards the pin,
• wherein the pin is configured axially movable relative to the armature, wherein the pin includes at least one recess configured to provide contact damping at an end oriented towards the armature,
• wherein the at least one recess is flow connected with a pass through opening that extends axially through an entirety of the armature when the end of the pin that is oriented towards the armature is in contact with the armature,
• wherein the at least one recess is open in a radial direction and in an axial direction of the pin.
