Abstract
An integral power steering gear with a spool-like valve within the piston is provided with washer springs to center the valve and self locking adjusting nuts for the springs. Nylon locking balls are positioned in radial holes to perform the locking function and are equally spaced around the nut so that the nut is maintained in the centered position for accurate spring loading at all times. Each of the balls is frictionally held within the mounting hole so as to be retained prior to installation. The balls are positioned substantially flush with the top of the threads of the nut. As the nuts are installed, the mating threads in the piston deform each ball providing full frictional engagement with at least one thread, and by bulges with the sides of adjacent threads. Bulges of the deformed ball also serve to stabilize the ball in the holes.
