AbstractA power steering system (3) includes a controller (1) and a control mechanism (3), which can be operated by way of a Bowden cable (5) having a core (7) and a sheath (6). The core (7) is connected directly mechanically to the control mechanism (3), and the sheath (6) is connected hydraulically to the control mechanism (3) by way of a control valve (8) and an operating cylinder (9). To prevent oscillations in the closed control circuit of the power steering system, the sheath (6), or the control piston (15) of the control valve (8) connected thereto, is provided with a damping device (18) to dampen the axial movement of the control piston (15). The damping device provides hydraulic damping of the control piston (15).
