Abstract

A multiplier for improved brake booster which comprises a body that is divided into two chambers by means of a partition and in each of its chambers, by a multiplier piston located on the side of the brake pedal and by a multiplier piston located on the cylinder side pattern, a constant pressure vacuum chamber and a variable pressure working chamber are formed, respectively, the two vacuum chambers being in permanent mutual connection, characterized in that the multiplier piston (12) on the side of the master cylinder is connected with a seal to the partition (9) by a roller diaphragm (29), and in that the body (8) has spacer pieces (21, 22) arranged in the longitudinal direction between which channels (23, 24, 25) are formed. By which the two vacuum chambers communicate with each other (14, 15). (Machine-translation by Google Translate, not legally binding)
