ABSTRACT:
The invention concerns a vacuum-type booster comprising a case divided internally into a vacuum chamber and a working chamber by a piston comprising a valve mechanism possessing a double valve (20) enabling, in the rest postion, a communication between the two chambers which are then isolated from the environment and, in the working position, an isolation of the vacuum chamber and a communication between the working chamber and the environment at atmospheric pressure, this valve mechanism being normally controlled by an actuating rod (12) extending out of the case. According to the invention, it comprises, in addition, an electromechanical device (50, 52, 54) for controlling the valve mechanism independent of the actuating rod (12).
