Abstract
The invention relates to a central valve for a pivot motor actuator. A housing tube of the central valve includes radial recesses for operating connections. A piston of the central valve has a center position. In the center position both radial recesses are covered by annular bars of the piston towards the tank drain connection by overlaps. Thus, pressure spikes from the operating connections to the check valves are strongly throttled.
