    • A steering valve (1) for power-steering gears contains two valve elements (4, 8), which are rotatable relative to each other. A corresponding centering unit (16) contains two centering elements (17, 18), which are rotation-fixed relative to the valve elements (4, 8) and which—together with the valve elements (4, 8)—are rotatable and axially displaceable relative to each other. Both centering elements (17, 18) feature radially aligned grooves, between which anti-friction elements (26) are inserted. Assembly is broken down into the following stages: The two valve elements (4, 8)—without centering unit (16)—are centrally aligned and linked via torsion bar spring (12). Separate from the steering valve (1), the two centering elements (17, 18) are pre-assembled in an assembly fixture and aligned in their mechanical center together with the anti-friction elements (26). The two aligned valve elements (4, 8) are linked to the two aligned centering elements (17, 18) by first linking the first centering element (17) to the first valve element (4), whereby the first centering element is aligned relative to the first valve element by means of a rotation-fixed axial guide element (20) and the link is non-rotatable but axially displaceable, and then linking the second centering element (18) to the second valve element (8) via longitudinal press fit, whereby the link is established by means of axial displacement of the entire centering unit (16) along the non-rotatable axial guide element (20).

    • A rotary steering control valve is provided of generally conventional construction having incorporated therein small diameter flow passages to effect throttling of return flow from a power cylinder. The throttling of exhaust from a power steering cylinder is known to be advantageous, e.g., for stifling noise, and the present invention has throttle passages incorporated directly in one of the relatively rotative valve members in such arrangement that when the valve is in neutral position for straight ahead steering, there is circulation of little pressure through the valve without throttling. However, during steering, the throttle passages are aligned in the exhaust circuit from either end of a double acting hydraulic motor so as to achieve exhaust flow throttling. The function is achieved by a novel arrangement of the coacting flow control edges and various grooves of the rotary valve plug and the encompassing sleeve which provide a multiplicity of return flow paths. Such grooves can be machined into the plug and sleeve, several at a time, by broaches and milling cutters in an economical manner.
    • 旋转转向控制阀设置有大体上常规的结构,其中结合有小直径流动通道以实现来自动力缸的回流的节流。 已知来自动力转向缸的排气节流是有利的,例如用于抑制噪声,并且本发明具有直接结合在一个相对旋转的阀构件中的节流通道,这样一来,当阀处于中间位置时 直前转向,通过阀门没有节流的循环压力很小。 然而,在转向期间,节流通道在排气回路中从双作用液压马达的任一端对准,以实现排气流量节流。 该功能通过提供多个返回流动路径的共同作用流动控制边缘和旋转阀塞和包围套筒的各种凹槽的新颖布置来实现。 这样的槽可以经济地加工成插头和套管,一次几次,由拉刀和铣刀加工。

    • Tools and techniques for performing a mass change to data are described. Attribute values in a data set can be replaced or overwritten based on a user request. The user request can be based on user selections and inputs made via a user interface. The user can limit the attribute values that are replaced based on attribute, attribute value, and/or other designation. The user interface can facilitate user execution of the mass change by presenting lists of attribute values and/or attributes to the user for selection. The list of attribute values can be limited based on a user designation of data elements for mass change. A mass change component can be configured to control directly or indirectly the user interface or portions thereof. The mass change component can initiate the mass change of the data, based on the user selections and inputs.
