Abstract (en)
[origin: US6213568B1] The present invention relates to a hydraulic brake system for automotive vehicles operable by independent force which includes a master brake cylinder preceded by a hydraulic brake force booster that has a booster piston and a working chamber to which an auxiliary pressure source is connectable, wherein a valve device operable by way of an electromagnetic drive is provided which establishes a hydraulic connection between the working chamber and an unpressurized pressure fluid supply reservoir in a first switching position and a connection between the working chamber and the auxiliary pressure source in a second switching position. To ensure low-noise operation of the brake system and a sensitively controlled volume delivery of the pressure fluid, the valve device is provided with a slide valve (20) of analog operation.
