Abstract
A spring and lever arrangement for imparting a spring force to a plunger of a control valve in a brake booster. The spring force is combined with an input force applied to the plunger during a brake application. A reaction force created by the resistance to movement of a pressurizing member by a output force developed in response to the input force overcomes the spring force and input force to control the development of an operational pressure differential such that the resultant output force for effecting a brake application varies as a nonlinear function.
