Abstract: The present invention relates to a brake force booster for automotive vehicles which includes a booster housing whose interior space is subdivided by a movable wall into a working chamber and a vacuum chamber, and a control housing which carries the movable wall and in which a control valve is arranged for controlling a pressure differential that acts upon the movable wall, the said control valve being operable by an operating rod by way of a valve piston and by an electromagnet. According to the present invention, the brake force booster is characterized in that the electromagnet is actuatable in dependence on the relative displacement between the valve piston and the control housing detected by a sensor. This arrangement makes possible a very simple control of a brake assist function because the signal of the sensor can be used both for the activation and the deactivation of the electromagnet. This means that the brake assist function can be triggered and/or terminated only on the basis of the signals of one single sensor.

Abstract: The present invention relates to an actuation device for an electrohydraulic brake system of the ‘brake-by-wire’ type which is configured as a tandem master cylinder with a first and a second piston that are respectively biased by a resetting spring in opposition to the actuating direction. The resetting spring associated with the first piston is additionally used as a travel simulator spring which determines the pedal characteristics, and a valve device is provided which closes or opens a hydraulic connection between a pressure chamber accommodating the travel simulator spring and a pressure fluid supply reservoir. To ensure that only a small lost travel must be covered in the event of failure of the independent brake force, the present invention discloses that the valve device is adapted to be closed by the movement of the second piston in relation to the housing of the tandem master cylinder, and is formed by a sealing sleeve arranged at the second piston and a channel that is designed in the area of movement of the sealing sleeve and connected to the pressure fluid supply reservoir.

Abstract: A pneumatic brake servo for motor vehicles having a servo housing, the interior of which is divided into at least one working chamber and at least one vacuum chamber by at least one axially movable wall which can be loaded with a pneumatic differential pressure, having a control valve which controls the differential pressure and is arranged in a control housing for connecting the working chamber to the vacuum chamber or to atmosphere. The movable wall includes a diaphragm plate and a rolling diaphragm, and the working chamber is sealed by a sealing ring which bears against the control housing and which is clamped in the radial direction in relation to a longitudinal axis of the brake servo. An actively loaded area of the movable wall is reduced by division of the working chamber into a prechamber and a main chamber to avoid stick/slip effects and reduce disruptive noises.
