Abstract
A spring and lever arrangement for imparting a spring force to a plunger of a control valve in a brake booster by operating a solenoid member during a brake application. Movement of the plunger by an operator input force allows a pressure differential to develop across a moveable wall and produce an original output force which is supplied to a pressurizing member. Resistance to movement of the pressurizing member creates a reaction force. The reaction force balances the spring force and operator input force to terminate the development of the pressure differential while correspondingly modifying the output force supplied to the pressurizing member. A switch allows an operator terminate the operation of the solenoid to effectively obviate the spring force and allow the original output force to be produced by the operator input force.
