ABSTRACT:
A brake pressure control apparatus for ABS in vehicles having a simple construction with a compact size is disclosed. The apparatus has a housing connected to a hydraulic pump to guide the pressure fluid to the apparatus, a step motor mounted on the upper surface of the housing to generate a rotational force, a bushing for guiding the pressure fluid flowed through the housing into the apparatus and a rotary valve rotatably accommodated in the bushing to transfer the pressure fluid which has flowed through the bushing to a wheel cylinder or a fluid tank. The apparatus can be manufactured with reduced cost, and can be easily applied to the ABS.
