<p>A method of controlling the initial stroke length 353 of an armature assembly 221 which includes a valve seat 215, and an end surface 229 in spaced axial relation from the valve seat, and which is moveable relative to a housing member 23 having an axis 27 and including an axial bore 45, and a counterbore 91 defined, in part, by an annular shoulder 93, said method comprising the steps of fabricating the armature assembly with the end surface, machining the valve seat 215 on the armature assembly at a given length from the end surface of the armature assembly, fabricating the housing member with the axis, the axial bore, and the counterbore defined, in part, by the annular shoulder, fabricating a bushing 125, fixing the bushing in the axial bore of the housing member, and machining a stop surface 135 on the bushing at a second given length from the annular shoulder of the counterbore in the housing member, whereby the initial stroke length of the armature assembly is determined in part by the difference between the first and second lengths. <IMAGE></p> |
