Abstract
A hydraulically supported power steering system is disclosed for motor vehicles including a double-acting hydraulic displacement unit or piston/cylinder unit for generating an auxiliary hydraulic force. For this purpose, the displacement body working spaces or piston working spaces can be acted upon by controllable hydraulic pressure or relieved of hydraulic pressure by means of associated conduits controlled by a servo-valve. The displacement unit or piston/cylinder unit also undertakes the function of a steering damper by means of damper valves arranged on the conduit connections. The damper valves include a perforated disc type of support part which can be clamped in the manner of a spacer ring between a bearing surface of a connecting mouthpiece arranged on a housing of one of the servo-valve and the displacement unit and an opposite bearing surface of a connecting part of a conduit, said connecting part being detachably connected to the connecting mouthpiece.
