<p>A pressure medium control unit for a servo steering, particularly for motor vehicles, has a valve body (1) with two control valves (8, 9) which rotate when the steering wheel rotates about the axis of the valve body (1). Both pistons (6, 7) of the control valves (8, 9) may be displaced by driving pins (4, 5) arranged at the fork end of a steering shaft and engaged with the pistons (6, 7). Due to the force of the springs (22, 23), the pistons (6, 7) are held on one side against the driving pins (4, 5). The contact lines (25, 26) between the driving pins (4, 5) and the valve pistons (6, 7), as well as the rotation axis of the fork end of the steering shaft are in one plane (E).</p> |
