Abstract
A brake pressure transducer is to be provided for a hydraulic vehicle brake system that can be actuated by initiating an actuating force (FB) via an actuating element (2) in order to generate a brake pressure for at least one wheel brake (3) by reducing the volume of a hydraulic chamber (4) and that is equipped with a brake force booster (13) in order to superimpose a primary servo force (FS1) on the initiated actuating force (FB). An additional hydraulic chamber (6) is provided whose volume likewise decreases on initiating the actuating force (FB). A pump (10, 10′) is disposed between the output of the additional hydraulic chamber (6) and the at least one wheel brake (3) that pumps in the direction from the additional hydraulic chamber (6) to the at least one wheel brake (3), and the output (10a) of the pump (10, 10′) is connected to the output of the hydraulic chamber (4) in order to superimpose a secondary servo force (FS2) on the initiated actuating force (FB) and/or the primary servo force (FS1).
