Abstract:
1. Valve assembly for slip-controlled automotive vehicle brake systems, comprising: a first valve closure member that is configured as a hydraulically actuatable spherical non-return valve, as well as a second valve closure member controllable electromagnetically by means of a magnet armature and a magnet coil, said second valve closure member being arranged in a valve accommodating bore including the first valve closure member and disposed in the valve housing in which the valve assembly is received, wherein both valve closure members in the valve housing are controllable irrespective of one another in terms of effect, including a first and a second valve accommodating member grouped in a construction unit having a first centric pressure fluid passage in the second valve accommodating member that is closable by means of the second valve closure member, and including a second pressure fluid passage that is adjacent to the first pressure fluid passage in the second valve accommodating member and closable by the first valve closure member, wherein an outside diameter of the first valve accommodating member is conformed to an inside diameter of the second valve accommodating member in such a way that the first valve accommodating member is inserted without clearance so far into the second valve accommodating member that the first valve closure member is supported either on a bore step in the second pressure fluid passage or on the first valve accommodating member, and wherein the second valve accommodating member is a turned metal part whose centric first pressure fluid passage is configured as a stepped bore whose expanded first stepped portion cuts across an expanded second stepped portion of the second pressure fluid passage arranged in parallel to the first pressure fluid passage.
