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.
