摘要： This invention relates to a method for manufacturing a plurality of longitudinally extending slots in the bore of a component (1). One example of such a component is the sleeve element of an automotive power steering rotary valve. More particularly the invention is directed towards a method of minimising burring of the slot edges of the sleeve component. The method comprises the steps of gripping the component in a gripping means (2) of a workholding device, performing a cutting operation (5) in which the slot is cut in the bore by a cutting tool (5), and further machining the edges of the slot by inserting a deburring means (30) into the bore and imparting relative angular reciprocation between the deburring means and the component.

摘要： A die for forming a Y-form rack portion (1) of a steering rack bar (25) from a blank by forging in which the die has at least three forming elements (44, 47, 48) relatively movable on application of forging pressure to the die to converge on a blank therein, a first of the forming elements (44) having in it cavities the shape of which corresponds to the shapes of the teeth (8) to be formed, second and third forming elements (47, 48) having forming faces to form longitudinal guide faces (45) on the Y-form rack portion (1) on the side thereof opposite the teeth (8). The three forming elements (44, 47, 48) are shaped and arranged to move together to converge on the blank to transform it into the final form in such a manner as to inhibit escape of the material of the blank between the first (44) and second (47) or first (44) and third (48) forming elements up to substantially the last instant of closure of the die. It is preferred to provide a fourth forming element (30) between the second (47) and third (48) forming elements which serves to guide their movement and to control the shape of a surface of the stem part (14) of the rack portion (1) lying between the longitudinal guide faces (4, 5) and it is further preferred to impart to the second (47) and third (48) forming elements a rolling motion as they converge on the blank. The die is preferably constructed to be used in a single direction impact press. A method of making a steering rack bar (25) having a Y-form rack portion (1) and a cylindrical portion (2) form a blank by forging is provided in which an accurately shaped and substantially cylindrical blank is first produced and the cylindrical portion (2) of the blank is held while the Y-form rack portion (1) is formed in a die of the configuration decribed above.

摘要： The present invention is a one piece sleeve for a rotary valve, the sleeve comprising an array of communication slots formed in the bore of the sleeve, characterised in that at least a portion of the floor of one of said slots is convex. Figure depicts sleeve (1b) with arcuate slot (21b) which has a convex floor and is open ended at both axial extremities of surface (17b) of bore (16b) of sleeve (1b). This slot may preferably be used as a return slot on the sleeve.
