Abstract

A brake power booster is equipped with a device for determining an input force introduced at a brake pedal. According to the present invention, the device which uses a pressure generator for measuring the input force is interposed between the end of an actuating rod, connected to the brake pedal, and a valve piston that actuates a control valve of the brake power booster. The pressure generator is exposed to the effect of a pressure which develops in a pressure chamber and is built up in an elastic substance or an elastomer.
