Abstract
For a hydraulic rack-and-pinion steering assembly for which a working piston is guided in a hydraulic cylinder which features an end limit stop by which, in an end position of the working piston, a path for the pressure agent supplied to the working piston by drill holes for the pressure agent is formed from the working space under pressure to a space of less pressure, in order to improve the hydraulic rack-and-pinion steering assembly such that it is simple to manufacture at limited cost, a rack-and-pinion steering assembly is improved by having, in the region of each pressure supply drill hole, at least one drill hole which can be executed and sealed from the housing exterior and which can be connected by means of a connecting line to the respective pressure supply.
