Output (English): The present invention is characterized in that a control valve (12) consists of three sealing seats (15, 16, 24) being concentrically arranged to each other, as well as a valve body (10) interacting with the sealing seats (15, 16, 24). The first sealing seat (15) is performed within a fundamental body (5) of the control valve (12) and the second sealing seat (16) is disposed in a valve piston (9), while the third sealing seat (24) is arranged on a sleeve (32) interacting with an electromagnet (20). The control valve (12) is provided with at least one part (36) serving for equalizing air pressure between a working and vacuum chambers (3, 4) in a pressure reducing phase within a brake booster (1) during backward movement of the third sealing seat (24) from the valve body (10).
