ABSTRACT:
A brake-pressure-transmitter arrangement (1) for a hydraulic motor-vehicle brake system, after an actuating force (F) has been introduced via an input member (brake pedal 2), by reduction in the volume of a hydraulic chamber (4) to be filled with brake fluid, provides a brake pressure at the output of the hydraulic chamber (4) for at least one wheel brake (3). In addition to the hydraulic chamber (4), there is a hydraulic chamber (6) for brake fluid, and the volume of this hydraulic chamber (6) is likewise reduced after introduction of the actuating force (F). To amplify the brake force, an output of this additional hydraulic chamber (6) is in fluid connection with the input side (10e) of a booster pump (10), which delivers brake fluid in the direction from the additional hydraulic chamber (6) to the at least one wheel brake (3). The output side (10a) of the booster pump (10) is in fluid connection with the output of the hydraulic chamber (4), so that an increased brake pressure is provided for the at least one wheel brake (3).
