Abstract:
A brake power booster including a bipartite actuating rod which is in force-transmitting connection with an actuating pedal and has a first and a second part telescopically slidable in each other, and a device for determining an input force, applied to the actuating pedal, which is interposed between the two parts, the first part being connected to the actuating pedal and including a bore,wherein the device for determining the input force is provided by a pressure generator which interacts with a pressure chamber that is filled with an elastic substance and is limited radially by the bore, and wherein the second part is a peak actuating a valve piston of a control valve of the brake power booster, the peak limiting the pressure chamber axially and being cemented to the stem by the elastic substance wherein the first part is a stem including a stop which permits entrainment of the peak when the actuating rod is subjected to tensile load.
