摘要： A die (22) for forming the toothed end of a steering rack bar from a cylindrical blank by forging comprising first and second die blocks (21, 22) adapted to converge on the blank. The die blocks incorporate opposed semi circular recesses to accommodate the blank, one recess incorporating the obverse form of the teeth, the recesses defining a main cavity (23) as the die blocks converge to their final position. Subsidiary recesses in the die blocks at the joint line there between define chambers (24), each side of the main cavity communicating with one of the chambers along the longitudinal extent of the main cavity. The chambers in cross section incorporate stop means (29) located remote from the main cavity (23) restricting further flow of blank material away therefrom. The chamber volume at the final position is equal to the difference of volume between the rack bar blank and the steering rack bar as finish forged over the toothed end thereof.
摘要翻译：一种模具（22），用于通过锻造形成转向齿杆条的带齿端与圆柱形坯料，所述锻造包括适于会聚在所述坯料上的第一和第二模块（21,22）。模块包括相对的半圆形凹槽以容纳坯料，一个凹陷结合了正面形式的齿，当模块会聚到其最终位置时，该凹槽限定主空腔（23）。在其间的连接线处的模块中的辅助凹部限定室（24），主腔的每一侧沿着主腔的纵向范围与一个腔室连通。横截面的腔室包括远离主腔（23）定位的止挡装置（29），从而限制坯料进一步流动。最终位置处的腔室容积等于齿条坯件和转向齿条杆之间的体积差异，其在齿形端部上锻造。

摘要： A hydraulic power steering rotary valve of generally conventional construction characterized in that the on-centre characteristics of the valve are governed by an arrangement of rolling elements (22) and notched elements (10, 20) arranged to produce a detent action between the input shaft (1) and the sleeve or driven member (2), the rolling elements (22) rolling between opposite surface contours of a pair of opposed notched elements (10, 20), the contours each including a convex surface the shape of which is such that a centering torque between the input shaft (1) and the sleeve or driven member (2) is produced which decreases for increasing amounts of rotation away from a neutral condition of the rotary valve.
