Abstract:
A brake booster having a valve body for retaining a plunger of a control valve, said plunger being connected by an input rod to a brake pedal, said brake pedal responding to an input force by an operator by moving the plunger to control communication of a source of pressure between a first chamber and a second chamber and create a pressure differential across a wall for developing an output force to effect a brake application, the input rod being characterized by a cylindrical tube having a first end and a second end with an annular rib located between the first end and the second end, a first annular groove located between said annular rib and said first end and a second annular groove located between the first annular groove and said first end such that an interior area of the cylindrical tube between said first and second annular grooves defines a socket, said cylindrical tube having a substantially rectangular shape with a hole therein perpendicular to the cylindrical tube adjacent said second end, said cylindrical tube being connected to said brake pedal by a pin located in said hole and resiliently connected to said plunger by snapping a semi-spherical ball thereon into said socket formed such an input force applied from the brake pedal through the pin is linearly transmitted directly through the cylindrical tube to move the plunger.
