Abstract

A pressure control valve arrangement is described for controlling a fluid pressure in an ABS brake system of a vehicle such that, in the event of a tendency of individual wheels of the vehicle to lock, the brake pressure in at least one associated brake cylinder can be adaptively adjusted, including: a housing in which is formed at least one pressure-medium-conducting pressure medium duct and in which is provided a diversion of the flow of the pressure medium within the pressure medium duct from a portion of the pressure medium duct leading in one direction into a portion of the pressure medium duct leading in another direction, in which the pressure medium duct is produced together with the housing by primary forming, and in which the cross section of the pressure medium duct is oval and the major dimension of the oval cross section and the central axis of the pressure medium duct are arranged in a common plane, and the minor dimension of the oval cross section is perpendicular to the plane.
