摘要： A brake power booster for automotive vehicles includes a control valve that is operable by an electromagnet irrespective of an actuating rod displacing a valve piston, the electromagnet actuating a third sealing seat which permits ventilation of the working chamber. The valve member of the control valve has passages which allow a pneumatic pressure compensation. To eliminate a pneumatic force component which counteracts the force generated by the electromagnet, the passages are provided radially outside the area delimited by the electromagnetically operable sealing seat on the sealing surface of the valve member.

摘要： 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.

摘要： The present invention relates to an operating unit for an electrohydraulic braking system of the ‘brake-by-wire’ type, which is designed as a tandem master cylinder having a first and a second piston biased by each one resetting spring in opposition to the actuating direction. The first pressure chamber of the tandem master cylinder is connected to a hydraulic chamber defined by a simulator element. The simulator element also defines a simulator chamber accommodating a simulator spring and connected to a pressure fluid supply reservoir. A valve device is provided which closes or opens the hydraulic connection between the simulator chamber and the pressure fluid supply reservoir. To disclose an operating unit that permits being manufactured at low costs and allows easy bleeding, according to the present invention, the simulator element is formed of a hydraulic simulator piston and the valve device is provided by a seal arranged at the second piston and by the mouth area of a channel designed in the range of movement of the seal, the said channel forming the hydraulic connection.

摘要： 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.
