Summary:A power steering assembly (20) for a hydraulic power steering system of motor vehicles having at least one hydraulic servo valve with a control element (26) for controlling the steering support dependent upon the relative rotation of the input shaft (22) relative to the output shaft (28), at least two planetary gear trains (30, 40) for transmitting the rotary movement of the input shaft (22) or the output shaft (28) onto the control element (26), and at least one actuator (50) for the relative adjustment of the control element (26) relative to the input shaft (22) or the output shaft (28) in order to influence the steering support characteristic.
