Abstract: A pinion valve body and a vehicle pinion valve assembly with the valve body are disclosed. The pinion valve body has a lower sleeve integrally formed by a sintering process along with upper splines to block an oil leakage and thus there are no needs any more for the conventional separate lower sleeve as well as the associated machining of sleeve fitting areas on the valve body and the process of press-fitting such sleeve all together, thereby effectively reducing the general manufacturing steps and their cost.
Abstract translation: 公开了一种具有阀体的小齿轮阀体和车辆小齿轮阀组件。 小齿轮阀体具有通过烧结过程与上花键一体形成的下套筒，以阻止漏油，因此常规分离的下套筒不再需要以及阀门上的套筒配合区域的相关加工 身体和将这种套筒压配合的过程，从而有效地减少了一般制造步骤及其成本。

Abstract: A filter includes top and bottom support frames, and one or more middle support frames, which are arranged in such a manner that a second stepped area recessed by a predetermined depth from the outer circumferential surfaces of the top and bottom support frames is formed by the top and bottom support frames and the middle support frames. A pressure control valve of an electronically controllable power steering apparatus includes: a hollow valve body having a first stepped area with a predetermined depth, the first stepped area being formed on the outer circumferential surface of the valve body, where a supply port is formed; and the above-mentioned filter, the filter being fitted in the first stepped area of the valve body. The filter can minimize change of pressure at the filter area while assuring smooth supply of the hydraulic fluid, and can reduce the number of parts, the number of fabricating steps, and the material costs of such a pressure control valve.
