Abstract
An arrangement for use with a valve system permits facilitated adaptation to conditions where modified lever ratios are desired while an actuation force requirement remains unaffected, or where a modified actuating force requirement is desired while lever ratios remain unchanged. In order to avoid or reduce costs associated with modification of the actuation force requirement of the valve system, a spring is provided which acts upon an operating element thereof, in addition to a pressure force, and codirectional therewith, against the actuating force in such manner that a predetermined actuating force requirement results. The invention finds particular significance in applications directed to vehicle braking systems.
