Abstract
A hydraulic valve control unit includes a valve body having an inner end, an outer end, and a fluid passageway. A housing has a bore which receives the inner end of the valve body. A sleeve has an open end which is placed over the outer end of the valve body. An armature is slideably mounted in the sleeve. A coil surrounds the sleeve for selectively moving the armature. A flux ring is disposed between the coil, housing and sleeve. The flux ring secures the sleeve to the valve body. The flux ring has a circumferential groove. A protrusion formed from the housing engages the groove to secure the flux ring, sleeve and valve body to the housing. A method of assembling the hydraulic control unit includes forming a bore in a housing, and inserting an inner end of a valve body into the bore. A sleeve is placed over an outer end of the valve body. A flux ring is pressed between the sleeve and the bore. The flux ring has a circumferential groove with an outer edge having a diameter which is larger than a diameter of the bore. The outer edge of the flux ring shears material from the housing around the bore to form a protrusion which engages the groove and secures the flux ring, sleeve and valve body to the housing. In another embodiment of the invention, a fastener secures at least the flux ring, sleeve and valve body to the housing.
