INTERFACE DESIGN OF TWO CLAMPED-TOGETHER PARTS Abstract of the Disclosure Two control valve housings each have a longitudinal bore receiving a valve spool. The housings are clamped together by two pairs of bolts located one on each side of the bores. Formed on one of the parts at the interface of the two parts and at opposite sides of each bolt is a pair of roughened surface areas which are prepared by milling or stamping. By means of such a surface preparing method projections are created which are deformed and serve as spacers between the two parts when they are clamped together. The two parts then touch themselves only in the roughened surface areas. Thus, when the two parts are clamped together any distortion in the area of the longitudinal bore is avoided and the valve spool can move in the longitudinal bore, noneffected by the force acting on the two parts.
