Abstract

A hydraulic rotary actuator within a stabilizer system divided into two parts is taught. A first stabilizer part is non-rotationally connected to a rotary actuator vane assembly, and a second stabilizer part is non-rotationally connected to a rotary actuator housing. The rotary actuator housing has hydraulic connections for hydraulic lines which form a flow connection to a hydraulic system. The two stabilizer parts can be rotated with respect to one another by the rotary actuator. The segments of the hydraulic lines which are connected to the rotary actuator, and are subject to possible deformation, are located in a plane which lies essentially perpendicular to the axis of rotation of the rotary actuator.
