Abstract
A control valve for controlling fluid flow in a hydraulic control unit of a vehicular brake system includes a flux tube having an end cap, a thick tube section, and a thin tube section defining an interior volume. An armature is slidably received in the interior volume of the flux tube. A coil is provided about the flux tube. A collar covers a portion of the thin tube section and is spaced from the thick tube section so that an air gap is provided between the coil and the portion of the thin tube section not covered by the collar.
