ABSTRACT:
The brake booster comprises a housing (10) in which is displaced a driving piston (12) having a hub (14) and separates a front chamber (16) from a rear chamber (18), the front chamber (16) is connected to a source of fluid under a first pressure, the rear chamber (18) is capable of being connected to a source of fluid under a second pressure, and the driving piston (14) is capable of being displaced from a rest position in response to the establishment of a difference between the first and second pressures between the two chambers (16, 18) and the pressure difference is controlled by a valve mechanism (20) associated with input control members (34, 62, 60). The connection (62) between the rear chamber (18) and the source of fluid under the second pressure is made by the input control members (34, 62, 60).
