Abstract

Disclosed is a brake booster for motor vehicles, the control valve (12) of which is operable, irrespective of an actuating rod (7) that displaces a valve piston (9), via an electromagnet (20), which actuates a third sealing seat (24) allowing ventilation of the working chamber (3). The third sealing seat (24) is provided on a sleeve (32) that cooperates with the electromagnet (20), and a ring (36) is arranged, which is displaceable in relation to the third sealing seat (24) and is supported on the sleeve (32) by the intermediary of an elastic or compressible element (37). In order to improve the dynamics and the sound behavior of the brake booster, the ring (36) is arranged radially within the sleeve (32) in such a manner that its areas (33), by which it is in contact with the valve body (10), at least partly release the passages (19) provided in the valve body (10).
