ABSTRACT:
A vehicle anti-lock brake system control unit having a control valve for a housing with a control valve bore therein. The control valve includes a sleeve with a moveable armature, and a coil surrounding the sleeve for moving the armature from a normally open valve position to a normally closed valve position. The control valve also includes a valve body having an outer end attached to the sleeve and an inner end seated within the control valve bore of the housing. A pole piece concentrically located within the valve body defines the flow passage through the valve and is fixed to the valve body by a swaged joint, thereby eliminating a threaded joint. The control valve is likewise held to or within the control unit by a non-threaded connection thereby eliminating altogether threaded connections in the control unit.
