ABSTRACT:
A filter assembly for a control valve for controlling fluid flow in a hydraulic control unit of a vehicular brake system includes a substantially annular filter body. The body has an inner surface, an outer surface, a first end, and a second end. The inner surface defines an axial bore from the first end to the second end of the body. A portion of the axial bore adjacent the first end receives a portion of a valve body. The filter body is disposed within a bore of a housing. The outer surface defines a first axial groove. The housing contains a valve. The first end of the filter body defines a first radially extending groove which extends between the axial bore and the first axial groove. A filter portion is disposed within the axial bore for filtering fluid flowing through the axial bore.
