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.
